11 2009-09-16 Akim Demaille <demaille@gostai.com>
12
13 lalr1.cc: factor the yytranslate_ invocation in make_SYMBOLS.
14 * data/c++.m4, data/lalr1.cc (parser::symbol_type): Change the
15 constructor to take a token_type instead of the (internal) symbol
16 number.
17 Call yytranslate_.
18 * data/variant.hh (b4_symbol_constructor_define_): Therefore,
19 don't call yytranslate_ here.
20
21 2009-09-16 Akim Demaille <demaille@gostai.com>
22
23 TODO: statistics.
24 * TODO (Figures): New.
25
26 2009-09-13 Joel E. Denny <jdenny@clemson.edu>
27
28 tests: clean up push.at test group titles.
29 * tests/push.at: Remove "Push Parsing: " from test group titles
30 because these are already under the banner "Push Parsing Tests".
31
32 2009-09-12 Alex Rozenman <rozenman@gmail.com>
33
34 Provide an additional sub-message for clarity.
35 Add "symbol not found in production" error message when
36 an "invalid reference" is detected in named references
37 resolution.
38 * src/scan-code.l: Update "invalid reference" case.
39 * tests/named-ref.at: Adjust test-cases.
40
41 2009-09-10 Joel E. Denny <jdenny@clemson.edu>
42
43 Clean up yacc.c a little.
44 * data/yacc.c: Clean up M4 for readability, and make output
45 whitespace more consistent. For the main parse function
46 comment, instead of saying "yyparse or yypush_parse", say either
47 "yyparse" or "yypush_parse" depending on which it actually is.
48
49 2009-09-10 Joel E. Denny <jdenny@clemson.edu>
50
51 Fix --enable-gcc-warnings.
52 * src/parse-gram.y (%printer <param>): Handle param_none.
53
54 2009-09-09 Akim Demaille <demaille@gostai.com>
55
56 lalr1.cc: syntax_error as exceptions.
57 It is common to use sort of factories in the user actions. These
58 factories may check some "syntactic" constraints that are not
59 enforced by the grammar itself. This is possible using YYERROR
60 within the action itself. Provide the user with a means to throw
61 a syntax_error exception.
62
63 * data/c++.m4 (b4_public_types_declare, b4_public_types_define):
64 Declare and define yy::parser::syntax_error.
65 * data/lalr1.cc: Include stdexcept.
66 (yy::parser::parse): Wrap the user action within a try/catch.
67 * data/glr.cc: Include stdexcept.
68
69 2009-09-09 Akim Demaille <demaille@gostai.com>

72 * data/c++.m4 (b4_public_types_define): Add missing inline to
73 implementations provided in headers.
74
75 2009-09-09 Akim Demaille <demaille@gostai.com>
76
77 %param: documentation.
78 * NEWS (2.6): Document %param, %lex-param, and %parse-param
79 changes.
80 * doc/bison.texinfo: Document that %lex-param and %parse-param
81 are n-ary.
82 Changes some examples to demonstrate it.
83 (Calc++ Parser): Use %param.
84
85 2009-09-09 Akim Demaille <demaille@gostai.com>
86
87 Regen.
88

97 * src/parse-gram.y (current_param): New.
98 (param_type): Add param_none.
99 (params): New nonterminal.
100 Use it.
101
102 2009-09-09 Akim Demaille <demaille@gostai.com>
103
104 Regen.
105
106 2009-09-09 Akim Demaille <demaille@gostai.com>
107
108 %param.
109 Provide a means to factor lex-param and parse-param common
110 declarations.
111
112 * src/parse-gram.y (param_type): New.
113 Define a %printer for it.
114 (add_param): Use it.
115 (%parse-param, %lex-param): Merge into...
116 (%parse): this new token.
117 Adjust the grammar to use it.
118 * src/scan-gram.l (RETURN_VALUE): New.
119 (RETURN_PERCENT_FLAG): Use it.
120 (RETURN_PERCENT_PARAM): New.
121 Use it to support %parse-param, %lex-param and %param.
122
123 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
124
125 Use aver not assert.
126 * src/output.c: Don't include assert.h.
127 (output_skeleton): Use aver not assert.
128 * src/system.h (aver): In documentation of why, add links to
129 Paul Eggert's explanations in the mailing lists.
130
131 2009-09-05 Alex Rozenman <rozenman@gmail.com>
132
133 Use "Unresolved reference" error message when no symbols were found
134 in a symbolic reference resolution. Remove .expr and -expr from
135 the shown reference when the reference is unresolved.
136 * src/scan-code.l: Change the error message, adjust location columns,
137 rename variable "exact_mode" to "explicit_bracketing".
138 * tests/named-ref.at: Adjust existing tests and add a new one.
139
140 2009-09-04 Akim Demaille <demaille@gostai.com>
141
142 Adjust synclines in src/parse-gram.[ch].
143 * tests/bison.in: Do some magic (including working around issues
144 with ylwrap) when this wrapper is used to compile
145 src/parse-gram.y.
146
147 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
148
149 Complain about unused %define variables and %code qualifiers.
150 * NEWS (2.5): Document.
151 * data/bison.m4 (b4_check_user_names): Complain instead of warn.
152 * doc/bison.texinfo (Decl Summary): Document complaint, and
153 improve %define documentation a little otherwise.
154 * tests/input.at (Reject unused %code qualifiers): Update.
155 (%define errors): Update.
156 (%define, --define, --force-define): Update.
157 (%define backward compatibility): Update.
158 (Unused %define api.pure): Update.
159 * tests/push.at (Push Parsing: Unsupported Skeletons): Update.
160
161 2009-09-03 Joel E. Denny <jdenny@clemson.edu>
162
163 Don't suppress warnings about unused parse.error.
164 * data/bison.m4 (b4_error_verbose_flag): Don't examine value of
165 %define variable parse.error unless b4_error_verbose_flag is
166 actually expanded in a skeleton.
167
168 2009-09-03 Akim Demaille <demaille@gostai.com>
169
170 * NEWS (2.4.2): Add "Internationalization" item.
171
172 2009-09-03 Akim Demaille <demaille@gostai.com>
173
174 bootstrap: fix/improve find_tool.
175 * bootstrap (find_tool): Improve error messages.
176 Fix typo about find_tool_names.
177
178 2009-08-29 Joel E. Denny <jdenny@clemson.edu>
179
180 Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
181 See
182 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>.
183 * src/scan-code.h (code_props_rule_action_init): Rename
184 named_ref arg to name so it doesn't shadow named_ref type. This
185 makes it consistent with the function definition in scan-code.l
186 anyway.
187
188 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
189
190 %define: accept unquoted values.
191 * NEWS (2.5): Group all %define changes together, and document
192 this one. Remove quotes in IELR and canonical LR entry.
193 * doc/bison.texinfo: Remove quotes in most examples throughout.
194 (Decl Summary): Update %define documentation.
195 (Table of Symbols): Likewise.
196 * src/ielr.c (LrType): Update documentation.
197 * src/parse-gram.y (content.opt): Add production for ID.

206
207 2009-08-28 Joel E. Denny <jdenny@clemson.edu>
208
209 %define lr.type: make values lowercase IDs.
210 That is, "LALR" => "lalr", "IELR" => "ielr", and
211 "canonical LR" => "canonical-lr".
212 * NEWS (2.5): Update documentation.
213 * doc/bison.texinfo (Decl Summary): Likewise.
214 * src/ielr.c (ielr): Use new values.
215 * src/ielr.h (ielr): Update documentation.

219 grammars.
220 * tests/reduce.at (AT_TEST_LR_TYPE): Likewise.
221
222 2009-08-27 Eric Blake <ebb9@byu.net>
223
224 scan-gram: avoid portability trap with ctype usage.
225 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
226 Avoid compiler warning.
227
228 2009-08-27 Joel E. Denny <jdenny@clemson.edu>
229
230 tests: use perl for printing special sequences to files.
231 And skip tests if perl is not available. This is better than
232 playing tricks with shell portability. Suggested by Akim
233 Demaille.
234 * tests/input.at (Bad character literals): Use it here for
235 omitting final newlines.
236 (Bad escapes in literals): Use it here for special characters.
237
238 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
239
240 tests: show a use of %define lr.default-reductions "consistent"
241 * tests/conflicts.at (%nonassoc and eof): Extend to test that it
242 prevents the omission of expected tokens for %error-verbose.
243
244 2009-08-26 Akim Demaille <demaille@gostai.com>
245
246 tests: portability fix.
247 * tests/input.at (Bad escapes in literals): Don't expect "echo
248 '\0'" to output \ then 0.
249
250 2009-08-26 Joel E. Denny <jdenny@clemson.edu>
251
252 Actually handle the yytable zero value correctly this time.
253 * data/bison.m4 (b4_integral_parser_tables_map): Don't mention
254 zero values in the YYTABLE comments.
255 * data/glr.c (yytable_value_is_error): Don't check for zero
256 value.
257 * data/lalr1.cc (yy_table_value_is_error_): Likewise.
258 * data/yacc.c (yytable_value_is_error): Likewise.
259 * data/lalr1.java (yy_table_value_is_error_): Likewise.
260 (yysyntax_error): Fix typo in code: use yytable_ not yycheck_.
261 * src/tables.h: In header comments, explain why it's useless to
262 check for a zero value in yytable.
263
264 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
265
266 More fixes related to last two patches.
267 * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
268 comments: zero indicates syntax error not default action.
269 * data/c.m4 (b4_table_value_equals): Comment that YYID must be
270 defined.
271 * data/glr.c (yyis_pact_ninf): Rename to...
272 (yypact_value_is_default): ... this.
273 (yyisDefaultedState): Update for rename.
274 (yyis_table_ninf): Rename to...
275 (yytable_value_is_error): ... this, and check for value zero
276 besides just YYTABLE_NINF.
277 (yygetLRActions): Check for default value from yypact. It
278 appears that this check is always performed before this function
279 is invoked, and so adding the check here is probably redundant.
280 However, the code may evolve after this subtlety is forgotten.
281 Also, update for rename to yytable_value_is_error. Because that
282 macro now checks for zero, a different but equivalent branch of
283 the if-then-else here is evaluated.
284 (yyreportSyntaxError): Update for rename to
285 yytable_value_is_error. The zero condition was mishandled
286 before.
287 (yyrecoverSyntaxError): Update for renames. No behavioral
288 changes.
289 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
290 New function.
291 (yy_table_value_is_error_): New function.
292 (parse): Use new functions where possible. No behavioral
293 changes.
294 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
295 The zero condition was mishandled before.
296 * data/yacc.c (yyis_pact_ninf): Rename to...
297 (yypact_value_is_default): ... this.
298 (yyis_table_ninf): Rename to...
299 (yytable_value_is_error): ... this, and check for value zero
300 besides just YYTABLE_NINF.
301 (yysyntax_error): Update for rename to yytable_value_is_error.
302 The zero condition was mishandled before.
303 (yyparse): Update for renames. No behavioral changes.
304 * src/tables.h: Improve comments about yypact, yytable, etc.
305 more. Most importantly, say yytable value of zero means syntax
306 error not default action.
307
308 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
309
310 Fix %error-verbose for conflicts resolved by %nonassoc.
311 * NEWS (2.5): Document.
312 * data/glr.c (yyreportSyntaxError): Fix this by checking
313 yyis_table_ninf.
314 * data/yacc.c (yysyntax_error): Likewise.
315 * data/lalr1.cc (yysyntax_error_): Fix this by checking
316 yytable_ninf_.
317 * data/lalr1.java (yysyntax_error): Likewise.
318 * tests/conflicts.at (%nonassoc and eof): Update expected output
319 and remove FIXME.
320
321 2009-08-25 Joel E. Denny <jdenny@clemson.edu>
322
323 Some code and documentation improvements.
324 * data/c.m4 (b4_table_value_equals): New macro to capture
325 some repeated code.
326 * data/glr.c (yyis_pact_ninf): Use it here.
327 (yyis_table_ninf): Likewise.
328 (yyreportSyntaxError): Improve internal comments.
329 * data/yacc.c (yyis_pact_ninf): New macro copied from glr.c.
330 Use it everywhere possible.
331 (yyis_table_ninf): Likewise.
332 (yysyntax_error): Improve internal comments.
333 * data/lalr1.cc (yysyntax_error_): Likewise.
334 * data/lalr1.java (yysyntax_error): Likewise.
335 * src/tables.h: Improve comments about yypact, yytable, etc.
336
337 2009-08-21 Joel E. Denny <jdenny@clemson.edu>
338
339 Use locale when quoting.
340 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use
341 quote rather than implementing quoting here.
342
343 2009-08-20 Eric Blake <ebb9@byu.net>
344
345 Make previous patch more robust.
346 * src/output.c (ARRAY_CARDINALITY): New macro, copied from
347 argmatch.h.
348 (output_skeleton): Use it.
349 Suggested by Akim Demaille.
350
351 Import latest m4/m4.m4.
352 * submodules/autoconf: Update to autoconf 2.64.
353 * configure.ac (M4_GNU_OPTION): New define.
354 * src/output.c (output_skeleton): Use it to resolve FIXME.
355 * NEWS: Mention this.
356
357 2009-08-19 Joel E. Denny <jdenny@clemson.edu>
358
359 Fix complaints about escape sequences.
360 Discussed starting at
361 <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
362 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
363 For a \0 and similar escape sequences meaning the null
364 character, report an invalid escape sequence instead of an
365 invalid null character because the latter does not actually
366 appear in the user's input.
367 In all escape sequence complaints, don't escape the initial
368 backslash, and don't quote when the sequence appears at the end
369 of the complaint line unless there's whitespace that quotearg
370 won't escape.
371 Consistently say "invalid" not "unrecognized".
372 Consistently prefer "empty character literal" over "extra
373 characters in character literal" warning for invalid escape
374 sequences; that is, consistently discard those sequences.
375 * tests/input.at (Bad escapes in literals): New.
376
377 2009-08-19 Akim Demaille <demaille@gostai.com>
378
379 doc: fixes.
380 * doc/bison.texinfo: Fix minor Texinfo errors.
381
382 2009-08-19 Akim Demaille <demaille@gostai.com>
383
384 tests: distcc compliance.
385 * tests/synclines.at (AT_SYNCLINES_COMPILE): Discard distcc's
386 error messages from the output.
387
388 2009-08-19 Akim Demaille <demaille@gostai.com>
389
390 variables: simplify the upgrade of namespace into api.namespace.
391
392 This patch simplifies "variables: rename namespace as
393 api.namespace", commit 67501061076ba46355cfd9f9361c7eed861b389c.
394 Suggested by Joel E. Denny in
395 http://lists.gnu.org/archive/html/bison-patches/2009-07/msg00006.html
396
397 * src/muscle-tab.c (muscle_percent_variable_update): New.
398 (muscle_percent_define_insert): Use it in replacement of the
399 previous tr invocation.
400 Remove variable_tr, no longer needed.
401 * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
402 Remove.
403 * data/c++.m4: No longer handle namespace -> api.namespace.
404 * tests/input.at (%define backward compatibility): Check that
405 namespace is treated as api.namespace.
406
407 2009-08-19 Akim Demaille <demaille@gostai.com>
408
409 doc: %initial-action to initialize yylloc.
410 Reported by Bill Allombert.
411 * doc/bison.texinfo: Set fill-column to 76.
412 (Location Type): Document the use of %initial-action to initialize
413 yylloc.
414
415 2009-08-19 Akim Demaille <demaille@gostai.com>
416
417 lalr1.cc: use state_type.
418 * data/lalr1.cc (yysyntax_error_): Use state_type.
419 Move argument names into yy*.
420
421 2009-08-19 Akim Demaille <demaille@gostai.com>
422
423 lalr1.cc: get rid of yyparse's yystate.
424 yystate and yystack_[0].state are equal, keep only the latter.
425 The former was also used as a temporary variable to compute the
426 post-reduction state. Move this computation into an auxiliary
427 function.
428
429 * data/glr.c (yyLRgotoState): Fuse variable definition and first
430 assignment.
431 * data/lalr1.cc (yy_lr_goto_state_): New.
432 (yyparse): Use it.
433 Replace remaining uses of yystate by yystate_[0].state.
434 Remove the former.
435
436 2009-08-19 Akim Demaille <demaille@gostai.com>
437
438 lalr1.cc: destroy $$ when YYERROR is called.
439 * data/lalr1.cc (yyreduce): Compute the resulting state before
440 running the user action so that yylhs is a valid symbol.
441 (yyerrorlab): Since yylhs is complete (it knows its type), we can
442 simply call yy_destroy_ to destroy $$ on YYERROR invocations.
443 * tests/c++.at (AT_CHECK_VARIANTS): Test YYERROR with variants.
444
445 2009-08-18 Joel E. Denny <jdenny@clemson.edu>
446
447 maint: update for gnulib's recent update-copyright changes
448 * gnulib: Update.
449 * .x-update-copyright (COPYING): Add as it's no longer implied
450 when .x-update-copyright is present.
451 * cfg.mk (update-copyright-local): Remove, now ignored.
452 (update-copyright): Declare update-b4-copyright as a dependency.
453
454 2009-08-17 Akim Demaille <demaille@gostai.com>
455
456 build: require gettext 0.17.
457
458 Suggested by Bruno Haible.
459 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html
460 * configure.ac: require gettext 0.17 to ensure compatibility with
461 gnulib.
462
463 2009-08-17 Akim Demaille <demaille@gostai.com>
464
465 build: lower gettext requirements.
466
467 Bison was uselessly requiring the formatstring macros from
468 gettext, which resulted in mo files not being installed on systems
469 that perfectly supported Bison mo files. Lower the requirement.
470 http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
471
472 * configure.ac: Require need-ngettext instead of
473 need-formatstring-macros.
474 Reported by Martin Jabocs.
475 Suggested by Bruno Haible.
476 * INSTALL: Restructure.
477 (Internationalization): New.
478
479 2009-08-14 Joel E. Denny <jdenny@clemson.edu>
480
481 maint: fix use of copyright year intervals.
482 * gnulib: Update.
483 * bootstrap.conf (gnulib_modules): Update getopt to getopt-gnu
484 as now recommended in gnulib/NEWS.

489
490 Make it easier to write deterministic tests.
491 Continues Akim's work from his 2009-06-10 commits.
492 * src/reader.c (check_and_convert_grammar): Don't add any
493 symbols after the first symbols_do invocation.
494 * src/symtab.c (symbols_sorted): New static global.
495 (user_token_number_redeclaration): Update comments.
496 (symbol_from_uniqstr): If a new symbol is being created, assert
497 that symbols_sorted hasn't been allocated yet.
498 (symbols_free): Free symbols_sorted.
499 (symbols_cmp, symbols_cmp_qsort): New functions.
500 (symbols_do): Sort symbol_table into symbols_sorted on first
501 invocation.
502 * tests/input.at (Numbered tokens): Recombine tests now that the
503 output should be deterministic across multiple numbers.
504
505 2009-08-12 Akim Demaille <demaille@gostai.com>
506
507 tests: GCC 4.5 compliance.
508 * tests/synclines.at (AT_SYNCLINES_COMPILE): Adjust to GCC 4.5's
509 messages about #error.
510
511 2009-08-12 Akim Demaille <demaille@gostai.com>
512
513 build: fix the generation of the documentation.
514 Some of our targets use "bison --help", but they can't depend on
515 "bison" itself (to avoid additional requirements on the user), so
516 they used to call "make src/bison" in the commands. Then
517 concurrent builds may fail: one make might be aiming one of its
518 jobs at compiling src/bison, and another job at generating the man
519 page. If the latter is faster than the former, then we have two
520 makes that concurrently try to compile src/bison.
521
522 This might also be a more convincing explanation for the failure
523 described in the patch "build: fix paths".
524
525 * Makefile.am (SUFFIXES): Initialize.
526 * build-aux/move-if-change: New, symlink to gnulib's.
527 * build-aux/local.mk: Ship it.
528 * doc/common.x: Remove, merged into...
529 * doc/bison.x: here.
530 * doc/local.mk (doc/bison.help): New.
531 ($(CROSS_OPTIONS_TEXI)): Depend on it.
532 Use src/bison.
533 (.x.1): Replace with...
534 (doc/bison.1): this explicit, simpler, target.
535 (common_dep): Remove, inlined where appropriate.
536 (SUFFIXES, PREPATH): Remove, unused.
537
538 2009-08-12 Akim Demaille <demaille@gostai.com>
539
540 gnulib: improve prefixing.
541 * configure.ac (gl_PREFIXED_LIBOBJS): Don't rename it, rather,
542 change the value of...
543 (gl_LIBOBJS): this.
544 Adjust more variables.
545 * etc/prefix-gnulib-mk (prefix_assignment): Don't rename
546 gl_LIBOBJS.
547 (prefix): Also transform rules whose targets have slashes.
548 Use $prefix liberally.
549 Map @MKDIR_P@ to $(MKDIR_P).
550 Prefix directories that are mkdir'd.
551
552 2009-08-12 Akim Demaille <demaille@gostai.com>
553
554 build: fix paths.
555 When using $(top_builddir) inconsistently, Make (including GNU
556 Make) is sometimes confused. As a result it may want to build
557 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
558 file, different names) concurrently, which, amusingly enough,
559 might end with:
560
561 ranlib lib/libbison.a
562 ranlib lib/libbison.a
563 make[2]: *** [lib/libbison.a] Segmentation fault
564
565 on OS X.
566
567 * doc/local.mk, src/local.mk: Do not use $(top_builddir) when not
568 needed.
569
570 2009-08-12 Akim Demaille <demaille@gostai.com>
571
572 distcheck: fix.
573
574 * examples/calc++/Makefile.am: (EXTRA_DIST): Ship calc.stamp.
575
576 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
577
578 * tests/local.mk (TESTSUITE_AT): Add named-refs.at.
579
580 2009-08-10 Joel E. Denny <jdenny@clemson.edu>
581
582 Miscellaneous code readability improvements.
583
584 * src/reader.c (reader): Move %define front-end variable
585 defaults and checking into...
586 (prepare_percent_define_front_end_variables): ... this new
587 function.
588
589 * src/scan-gram.l (INITIAL): For consistency with string
590 literals, don't store open quote on character literal. It's
591 discarded before returning anyway.
592 (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
593 Make length test more readable, and make the character stored
594 for an empty literal more obvious while consistent with the
595 previous behavior.
596
597 * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
598 USER_NUMBER_HAS_STRING_ALIAS throughout.
599 * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
600 that is repeated in symtab.h. Improve argument names to make it
601 clear which side of the symbol-string alias pair is which.
602 (symbol_check_alias_consistency): Improve local variable names
603 for the same purpose.
604 * src/symtab.h (struct symbol): Make comments about aliases
605 clearer.
606 (symbol_make_alias): Improve comments and argument name.
607 * src/output.c (token_definitions_output): Update for rename to
608 USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
609
610 2009-08-08 Alex Rozenman <rozenman@gmail.com>
611
612 Convert "misleading reference" messages to warnings.
613 * src/scan-code.l: New function 'show_sub_messages', more
614 factoring.
615 * tests/named-ref.at: Adjust tests.
616
617 2009-08-06 Joel E. Denny <jdenny@clemson.edu>

619 maint: run "make update-copyright"
620
621 2009-08-06 Joel E. Denny <jdenny@clemson.edu>
622
623 maint: make update-b4-copyright easier to use
624 * build-aux/update-b4-copyright: In warnings, report line
625 numbers rather than character positions.
626 * cfg.mk (update-copyright-local): Set to update-b4-copyright so
627 that update-copyright runs it.
628 * gnulib: Update.
629
630 2009-08-05 Joel E. Denny <jdenny@clemson.edu>
631
632 maint: clean up update-b4-copyright code
633 * build-aux/update-b4-copyright: Do not accept 2-digit
634 UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
635 Don't accept a `[' in a b4_copyright argument.
636 Format code more consistently.
637 Don't assume b4*copyright never occurs.
638
639 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
640
641 maint: automate b4_copyright updates.
642 * Makefile.am (update-b4-copyright): New target rule.
643 * build-aux/local.mk (EXTRA_DIST): Add update-b4-copyright.
644 * build-aux/update-b4-copyright: New.
645 * data/yacc.c: Remove stray characters around b4_copyright
646 invocations.
647
648 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
649
650 maint: automate annual package-wide copyright-year update.
651 * .x-update-copyright: New.
652 * Makefile.am (EXTRA_DIST): Remove maint.mk.
653 * bootstrap.conf (gnulib_modules): Add maintainer-makefile and
654 update-copyright. Remove gnumakefile, which is implied by
655 maintainer-makefile.
656 * cfg.mk (bootstrap-tools): Copy from old maint.mk.
657 * gnulib: Update.
658 * maint.mk: Remove, now copied from gnulib.
659 * examples/extexi: Add missing "(C)" in copyright statement so
660 update-copyright can recognize it.
661 * src/LR0.h: Likewise.
662 * src/print.h: Likewise.
663 * src/print_graph.h: Likewise.
664 * src/gram.c: Add missing comma in copyright statement.
665 * src/gram.h: Likewise.
666
667 2009-08-04 Joel E. Denny <jdenny@clemson.edu>
668
669 Fix "make distcheck".
670 * examples/calc++/Makefile.am: Say $(srcdir)/calc.stamp instead
671 of just calc.stamp.
672
673 2009-08-01 Joel E. Denny <jdenny@clemson.edu>
674
675 Pacify "gcc -Wunused" for the input function from Flex.
676 Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
677 and later.
678 * src/scan-code.l: Add "%option noinput", which I cannot find in
679 the Flex manual, but which Flex has supported since at least as
680 far back as 2.5.4. However, if any of our developers still use
681 Flex 2.5.4, they'll need to stop configuring with
682 --enable-gcc-warnings because "%option noinput" didn't work
683 correctly until Flex 2.5.6.
684 * src/scan-gram.l: Likewise.
685 * src/scan-skel.l: Likewise.
686
687 2009-07-31 Alex Rozenman <rozenman@gmail.com>
688
689 Fix --enable-gcc-warnings problems.
690 * src/reader.c: Adjust variable names.
691 * src/scan-code.l: Fix prototypes and adjust names.
692 * src/named-ref.c: Remove redundant "if".
693
694 2009-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
695
696 Fix a --enable-gcc-warnings problem.
697 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
698 variable.
699
700 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
701
702 Warn about character literals not of length one.
703 * NEWS (2.5): Document.
704 * src/scan-gram.l (INITIAL): Remove comment that we don't check
705 the length.
706 (SC_ESCAPED_CHARACTER): Warn if length is wrong.
707 * tests/input.at (Bad character literals): New test group.
708
709 2009-07-24 Alex Rozenman <rozenman@gmail.com>
710
711 Fix some memory leaks.
712 * src/named-ref.c: Add a pointer check (named_ref_free).
713 * src/scan-code.l: New function (variant_table_free). Called in
714 code_scanner_free.
715 * src/symlist.c: Call to named_ref_free (symbol_list_free).
716
717 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
718
719 * src/lalr.c (state_lookahead_tokens_count): Correct comment.
720
721 2009-07-22 Joel E. Denny <jdenny@ces.clemson.edu>
722
723 Some M4 cleanup in the testsuite.
724 Suggested by Eric Blake at
725 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
726 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
727 complicate the code by distinguishing between a missing value
728 and an empty string value for an optional argument. This fix is
729 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
730 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
731 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
732 arguments are not needed because of the following changes.
733 Fix stale comments.
734 Bison developers should use GNU M4 and should not use
735 POSIXLY_CORRECT when building the test suite, so do not
736 complicate the code by avoiding $10 and above.
737 Do not quote an empty string value for an optional argument, and
738 do not distinguish between a missing value and an empty string
739 value.
740
741 2009-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
742
743 Revert unnecessary column realignment in --help output.
744 Reported by Akim Demaille at
745 <http://lists.gnu.org/archive/html/bison-patches/2009-06/msg00010.html>.
746 * src/getargs.c (usage): Here.
747
748 2009-07-04 Alex Rozenman <rozenman@gmail.com>
749
750 Alphabetical order in src/local.mk.
751 * src/local.mk: Adjust.
752
753 2009-07-04 Alex Rozenman <rozenman@gmail.com>
754
755 Style changes and factoring.
756 * src/named-ref.h: Add comments.
757 * src/parse-gram.y: Readability and style changes.
758 * src/reader.c: Factoring: assign_named_ref function.
759 * src/scan-code.l: Factoring and style changes. Rename
760 parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
761 Use "unsigned" type for variant index. Improve readablity.
762 * src/scan-gram.l: Change error messages and add comments.
763 * src/symlist.h: symbol_list_null: New function decl.
764 * src/symlist.c: symbol_list_null: Implement here.
765 * tests/named-refs.at: Adjust for new error messages.
766
767 2009-06-29 Eric Blake <ebb9@byu.net>
768
769 scan-code: avoid compiler warnings
770 * src/scan-code.l (parse_named_ref): Use correct specifiers.
771
772 2009-06-29 Akim Demaille <demaille@gostai.com>
773
774 build: avoid concurrent extraction of calc++.
775 * examples/calc++/Makefile.am (calc.stamp): New.
776 Depend on it to create the sources of calc++ so that concurrent
777 builds don't launch several "extexi" in parallel.
778 Not only this is inefficient, this also builds incorrect sources
779 with several extractions mixed together.
780
781 2009-06-29 Akim Demaille <demaille@gostai.com>
782
783 parse.error: fix.
784 * data/bison.m4: Move code related to specific variables after the
785 definition of the variable-maintaining macros so that we don't
786 "invoke" b4_percent_define_check_values before it is defined.
787
788 2009-06-29 Akim Demaille <demaille@gostai.com>
789
790 variables: parse.error
791
792 Implement, document, and test the replacement of %error-verbose
793 by %define parse.error "verbose".
794 * data/bison.m4 (b4_error_verbose_if): Reimplement to track the
795 values of the parse.error variable.
796 Make "simple" its default value.
797 Check the valid values.
798 * src/parse-gram.y: Use %define parse.error.
799 (PERCENT_ERROR_VERBOSE): New token.
800 Support it.
801 * src/scan-gram.l: Support %error-verbose.
802
803 * doc/bison.texinfo (Decl Summary): Replace the documentation of
804 %define error-verbose by that of %define parse.error.
805 * NEWS: Document it.
806
807 * tests/actions.at, tests/calc.at: Use parse.error instead of
808 %error-verbose.
809
810 2009-06-27 Alex Rozenman <rozenman@gmail.com>
811
812 Implement support for named symbol references.
813 * src/parse-gram.y: Add new syntax (named_ref.opt).
814 * src/reader.c: Store named refs in symbol lists.
815 * src/reader.h: New argument for symbol_append and
816 action_append functions.
817 * src/scan-code.h: Add new field (named_ref) into
818 code_props data structure. Keeps named ref of midrule
819 actions.
820 * src/scan-code.l: Support for named refs in semantic
821 action code. New function 'parse_named_ref'.
822 * src/scan-gram.l: Support bracketed id.
823 * src/symlist.c: Store named refs in symbol lists.
824 * src/symlist.h: New field in symbol list: named_ref.
825 * src/named-ref.h: New file, a struct for named_ref.
826 * src/named-ref.cp: New file, named_ref_new function.
827 * src/local.mk: Add two new files.
828 * tests/testsuite.at: Include new test group:
829 * tests/named-refs.at: this new file.
830
831 2009-06-25 Akim Demaille <demaille@gostai.com>
832
833 hash: check insertion for memory exhaustion.
834 * src/uniqstr.c (uniqstr_new): New.
835
836 2009-06-24 Akim Demaille <demaille@gostai.com>
837
838 variables: rename namespace as api.namespace.
839 Discussed in
840 http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00033.html
841
842 * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
843 New.
844 (b4_percent_define_use): New.
845 Use it where applicable.
846 * data/c++.m4: Replace uses of the variable "namespace" by
847 "api.namespace".
848 Default the latter to the former.
849 * doc/bison.texinfo (Decl Summary): Document "namespace" as
850 obsolete.
851 Document api.namespace.
852 Use @samp to document %define uses, keep @code for identifiers.
853 * NEWS: Likewise.
854 * tests/c++.at, tests/input.at: Test api.namespace instead of
855 namespace. (The tests passed with namespace.)
856
857 2009-06-11 Akim Demaille <demaille@gostai.com>
858
859 style changes.

866 xml: beware of user strings used to give a %prec to rules.
867 * tests/conflicts.at (%prec with user strings): New.
868 * src/gram.c (grammar_rules_print_xml): Escape the precedence for
869 XML output.

881 * tests/local.mk (RUN_TESTSUITE): New.
882 (check-local, installcheck-local, maintainer-check-g++)
883 (maintainer-check-posix, maintainer-check-valgrind): Use it.
884
885 2009-06-10 Akim Demaille <demaille@gostai.com>
886
887 deterministic test suite.
888 Some consistency checks on symbols are performed after all the
889 symbols were read, by an iteration over the symbol table. This
890 traversal is nondeterministic, which can be a problem for test
891 cases.
892 Avoid this.
893 Addresses another form of nondeterminism reported by Joel E. Denny.
894 http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00023.html
895
896 * tests/input.at (Numbered tokens): Split the hexadecimal/decimal
897 test in two.
898 Use different file names for the three tests to make the
899 maintenance easier.
900
901 2009-06-10 Akim Demaille <demaille@gostai.com>
902
903 gnulib: update.

907 * src/symtab.c (symbol_from_uniqstr, semantic_type_from_uniqstr):
908 Call xalloc_die on hash_insert failures.
909 Requested by the new __warn_unused_result__ attribute of
910 hash_insert.

927 * doc/local.mk ($(CROSS_OPTIONS_TEXI)): Don't generate ignored
928 errors, they pollute the output.
929
930 2009-05-22 Joel E. Denny <jdenny@ces.clemson.edu>
931
932 Convert multiple variable definition warnings to complaints.

968

970 * data/bison.m4 (b4_check_user_names): In header comments, say
971 "user occurrence" instead of "grammar occurrence".

978
979 2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>

981 Handle a trailing `:' in a user-supplied C++ namespace better.
982 * data/c++.m4 (b4_namespace_close): Don't let it be printed
983 among the closing braces here. This fix might make the
984 generated code easier to debug, but otherwise it should be
985 insignificant because a trailing `:' is a C++ error already.

988

1165 (Language and Grammar): Bison is no longer limited to LALR(1)
1166 restrictions.
1167 (GLR parsing): Say deterministic or LR(1) rather than LALR(1)
1168 when trying to distinguish from GLR. Talk about LR(1) grammars
1169 rather than LALR(1) grammars.

1214 (compute_lookahead_tokens): Don't free goto_follows yet. Now
1215 handled in ielr.
1216 (initialize_LA): Export it. Move lookback allocation to...
1217 (lalr): ... here because, for canonical LR, initialize_LA must
1218 be invoked but lookback and much of the rest of LALR isn't
1219 needed.
1220 * main.c (main): Instead of lalr, invoke ielr, which invokes
1221 lalr.
1222 * src/reader.c (reader): Default lr.type to "LALR".
1223 Default lr.default_rules to "accepting" if lr.type is "canonical

1266 is "accepting", then only mark the accepting state as

1269 lr.default_rules is "accepting".
1270 * src/tables.c (action_row): If lr.default_rules is not "all",
1271 then disable default rules in inconsistent states.
1272 * src/print.c (print_reductions): Use this opportunity to
1273 perform some assertions about whether lr.default_rules was

1410 parser: handle %locations as %define locations.
1411 * src/getargs.h, src/getargs.c (locations_flag): Remove.
1412 * src/getargs.c, src/scan-code.l: Use muscle_percent_define_ensure
1413 to set "locations" to true.
1414 * src/output.c (prepare): Don't output "locations".
1415 * src/scan-gram.l (%locations): Handle it as a %<flag>.
1416 * src/parse-gram.y: It's no longer a token.
1417 Don't handle it.
1418 * data/bison.m4 (b4_locations_if): Define it with

1450 Replace BISON_PROG_GNU_M4 with Autoconf's AC_PROG_GNU_M4.
1451 If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
1452 requirements for a correct m4 are stricter.
1453 * m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
1454 * configure.ac: Update to use AC_PROG_GNU_M4.
1455 Reported by Eric Blake.

1470 Factor %FLAG at scan level.
1471 * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
1472 definitions and associated rules, replaced by....
1473 (PERCENT_FLAG): this new token type, and rule.
1474 * src/scan-gram.l (RETURN_PERCENT_FLAG): New.
1475 Use it for %debug and %error-verbose.

1492 2009-04-03 Akim Demaille <demaille@gostai.com>
1493
1494 Treat %error-verbose as %define error_verbose.
1495 This allows to pass -Derror_verbose on the command line. Better
1496 yet, it allows to pass -Derror_verbose=$(ERROR_VERBOSE), with
1497 ERROR_VERBOSE being defined as false or true.
1498 * data/bison.m4 (b4_percent_define_if_define): Instead of relying
1499 on b4_percent_define_ifdef, for does not check the defined value,
1500 but only whether the symbol is defined, rely on
1501 b4_percent_define_flag_if, so that a value of "false" is processed
1502 as a false.
1503 If not defined, define the flag to "false".
1504 (b4_error_verbose_if): New.
1505 * data/glr.c, data/lalr1.cc, data/yacc.c: Use it instead of
1506 b4_error_verbose_flag.
1507 * src/getargs.h, src/getargs.c (error_verbose_flag): Remove.

1514 Reported by Akim Demaille at
1515 <http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
1516 and discussed again starting at
1517 <http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
1518 * data/bison.m4 (b4_percent_define_default): Leave syncline blank
1519 because location information is bogus.
1520 Use angle brackets to delimit fake file name because square brackets
1521 look like underexpanded m4. Choose a better fake file name.
1522 Use negative line numbers.
1523 * src/muscle_tab.c (muscle_percent_define_default): Likewise.
1524 * src/location.c (location_print): If line for a boundary is negative,
1525 only print that boundary's file name.
1526 * src/location.h: Document that.
1527 * tests/skeletons.at (%define Boolean variables: invalid skeleton
1528 defaults): Update output.

1566 GCC 4.3 now warns about "a || b && c" and asks for explicit
1567 parentheses.
1568 Reported by Alexandre Duret-Lutz.
1569 * data/location.cc: Update copyright years.
1570 (Position::operator==): Use parens to make precedence explicit.
1571 Compare lines and columns first, as they are more likely to be
1572 different, and they are faster to compare.

1595 Use locations in the variant example.
1596 Yes, this obfuscates the point of this example, variants only.
1597 But glr.cc cannot work (yet?) without locations. This change
1598 makes it easier to use this example with glr.cc.
1599
1600 * examples/variant.yy (assert): %define it.
1601 (locations): Request them.
1602 (yylex): Bind the location to the stage.

1714 * data/lalr1.cc: here.
1715 There is no good reason to keep it private (and it is convenient

1857
1858 Fix regeneration of atconfig.
1859 * tests/local.mk (tests/atconfig): The rule was incorrect, but
1860 remove it: now that there is no tests/Makefile.am, the top-level
1861 Makefile properly updates atconfig when needed.
1862
1863 2008-12-07 Di-an Jan <dianj@freeshell.org>
1864
1865 Implement the FIXME that ends an user action with a semicolon
1866 if it seems necessary.
1867 * src/scan-code.l (flex rules section): Flag cpp directive from
1868 any `#' to the first unescaped end-of-line. Semicolon is not
1869 needed after `;', `{', '}', or cpp directives and is needed after
1870 any other token (whitespaces and comments have no effect).
1871 * tests/actions.at (Fix user actions without a trailing semicolon):
1872 New test.
1873 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
1874 to make user actions complete statements.
1875 Adjust column numbers in error messages.
1876 * tests/regression.at (Fix user actions without a trailing semicolon):
1877 Remove. Covered by new test.

1888 function.
1889
1890 2008-12-02 Eric Blake <ebb9@byu.net>
1891
1892 Build testsuite with newer autoconf.
1893 * tests/output.at (m4_expand): Don't override in newer autoconf,
1894 where the underlying implementation changed.
1895 * tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
1896 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
1897 (_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
1898 (_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
1899 since some of them contain unbalanced ')'.

1901 2008-12-01 Akim Demaille <demaille@gostai.com>
1902
1903 Use b4_symbol for printers and destructors everywhere.
1904 * data/bison.m4 (b4_symbol_action_location): New.
1905 * data/c.m4 (b4_symbol_actions): Remove.
1906 Adjust all callers to use by b4_symbol_foreach and the corresponding
1907 b4_symbol_printer/destructor macro.
1908 * data/glr.cc: Adjust.
1909 * data/lalr1.java: Adjust the %destructor sanity check.
1910 * src/output.c (symbol_code_props_output): Remove, we no longer
1911 need the b4_symbol_printers/destructors tables.
1912
1913 2008-12-01 Akim Demaille <demaille@gostai.com>
1914
1915 Use b4_symbol_case_.
1916 * data/lalr1.cc, data/bison.m4 (b4_symbol_action): Use
1917 b4_symbol_case_.
1918
1919 2008-12-01 Akim Demaille <demaille@gostai.com>
1920
1921 Move b4_symbol based macro to bison.m4.
1922 * data/lalr1.cc (b4_symbol_, b4_symbol, b4_symbol_if)
1923 (b4_symbol_action, b4_symbol_destructor, b4_symbol_printer)
1924 (b4_symbol_case_, b4_symbol_foreach, b4_type_action_)
1925 (b4_type_foreach): Move to...
1926 * data/bison.m4: Here.
1927 * data/lalr1.cc (b4_symbol_action): Specialize for C++: use
1928 b4_symbol_value_template instead of b4_symbol_value.
1929
1930 2008-12-01 Akim Demaille <demaille@gostai.com>
1931
1932 b4_symbol/type_foreach.
1933 * data/lalr1.cc (b4_symbol_foreach, b4_type_foreach): New.
1934 Use them.
1935
1936 2008-12-01 Akim Demaille <demaille@gostai.com>
1937
1938 Use the symbol properties to output the printer/destructor for lalr1.cc.
1939 Instead of defining complex list of tuples to define various
1940 properties of the symbols, we now prefer to define symbols as
1941 "structs" in m4: using the symbol key (its number), and the
1942 property name, b4_symbol gives it value. Use this to handle
1943 destructors and printers.
1944
1945 * src/output.c (CODE_PROP): New.
1946 (prepare_symbol_definitions): Use it to define the printer and
1947 destructor related attributes of the symbols.
1948 * data/lalr1.cc (b4_symbol_actions): Rename as...
1949 (b4_symbol_action): this.
1950 Use b4_symbol instead of 6 arguments.
1951 (b4_symbol_printer, b4_symbol_destructor): New.
1952 Use them instead of b4_symbol_actions.
1953
1954 2008-12-01 Akim Demaille <demaille@gostai.com>
1955
1956 Avoid capturing variables too easily.
1957 * src/muscle_tab.h (MUSCLE_INSERT_BOOL, MUSCLE_OBSTACK_SGROW): Use
1958 v__ and p__ instead of v and p.
1959
1960 2008-12-01 Akim Demaille <demaille@gostai.com>
1961
1962 Remove spurious empty line before syncline.
1963 * data/bison.m4 (b4_syncline): Don't output an empty line before
1964 the output.
1965
1966 2008-11-26 Akim Demaille <demaille@gostai.com>
1967
1968 Convert lib/Makefile.am into lib/local.mk.
1969 The real problem is rather gnulib.mk, which itself is extracted
1970 from a Makefile.am that gnulib expects to the "recursive". The
1971 tool prefix-gnulib-mk converts such a gnulib.mk to be
1972 non-recursive. Also, some AC_SUBST variables need to be adjusted.
1973
1974 * etc/prefix-gnulib-mk: New.
1975 * bootstrap (slurp): Use it to convert further gnulib.mk.
1976 No longer try to avoid re-creation of lib/gnulib.mk as the changes
1977 are deeper.
1978 * lib/Makefile.am: Rename as...
1979 * lib/local.mk: this.
1980 Adjust to be prefixed.
1981 * Makefile.am, configure.ac: Adjust.
1982 * src/local.mk (AM_CPPFLAGS): Extend it, don't define it.
1983
1984 2008-11-26 Akim Demaille <demaille@gostai.com>
1985
1986 s/_FLAGS/FLAGS/.
1987 * tests/local.mk (TESTSUITE_FLAGS, AUTOTEST_FLAGS): Rename as...
1988 (TESTSUITEFLAGS, AUTOTESTFLAGS): these to compy with the GCS.
1989 Reported by Eric Blake.
1990
1991 2008-11-26 Akim Demaille <demaille@gostai.com>
1992
1993 Use b4_parser_tables_define in glr.cc.
1994 * data/glr.c: Use b4_parser_tables_define instead of defining the
1995 (deterministic integral) tables by hand.
1996
1997 2008-11-26 Akim Demaille <demaille@gostai.com>
1998
1999 Use b4_parser_tables_define in Java.
2000 * data/java.m4 (b4_typed_parser_table): Rename as...
2001 (b4_typed_parser_table_define): this, for consistency.
2002 Accept a comment as $4.
2003 Move $2 into yy*_.
2004 (b4_integral_parser_table): Rename as...
2005 (b4_integral_parser_table_define): this.
2006 * data/lalr1.java: Adjust all uses.
2007 Use b4_parser_tables_define instead of generation by hand.
2008
2009 2008-11-26 Akim Demaille <demaille@gostai.com>
2010
2011 Prepare the convergence bw C style and Java table generation.
2012 * data/bison.m4 (b4_tables_map, b4_tables_declare)
2013 (b4_tables_define): Rename as...
2014 (b4_integral_parser_tables_map, b4_parser_tables_declare)
2015 (b4_parser_tables_define): these.
2016 * data/c.m4 (b4_table_define): Rename as...
2017 (b4_integral_parser_table_define): this.
2018 * data/lalr1.cc: Adjust.
2019 (b4_table_define, b4_table_declare): Rename as...
2020 (b4_integral_parser_table_define)
2021 (b4_integral_parser_table_declare): these.
2022 (yyrline_): Move the comment where it is actually used.
2023 * data/yacc.c: Adjust.
2024 (yyrline): Use b4_integral_parser_table_define.
2025
2026 2008-11-26 Akim Demaille <demaille@gostai.com>
2027
2028 Regen.
2029 * src/parse-gram.h, src/parse-gram.c: Regen.
2030
2031 2008-11-26 Akim Demaille <demaille@gostai.com>
2032
2033 Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.
2034 * data/lalr1.cc (b4_tables_map): Move to...
2035 * data/bison.m4: here.
2036 Update the comment for yytable during the flight.
2037 (b4_tables_declare, b4_tables_define): New.
2038 * data/lalr1.cc: Use them.
2039 * data/c.m4 (b4_table_define): New.
2040 * data/yacc.c: Use b4_tables_define instead of output the tables
2041 by hand.
2042 * tests/regression.at (Web2c Actions): Adjust the expected output,
2043 the order of the tables changed.
2044
2045 2008-11-26 Akim Demaille <demaille@gostai.com>
2046
2047 Get rid of (yy)rhs and (yy)prhs.
2048 These tables are no longer needed in the parsers, and they don't seem to
2049 be useful. They are not documented either.
2050
2051 * src/output.c (prepare_rules): Get rid of rhs and prhs.
2052 Adjust the computation of (yy)r2.
2053
2054 2008-11-26 Akim Demaille <demaille@gostai.com>
2055
2056 Rule length is unsigned.
2057 * src/gram.h, src/gram.c (rule_rhs_length): Return a size_t.
2058
2059 2008-11-26 Akim Demaille <demaille@gostai.com>
2060
2061 Get rid of lalr1-split.cc.
2062 It was no longer maintainer.
2063
2064 * data/lalr1-split.cc: Remove.
2065 * etc/bench.pl.in (bench_fusion_parser): Remove.
2066 Adjust.
2067
2068 2008-11-26 Akim Demaille <demaille@gostai.com>
2069
2070 Use yy* consistently.
2071 * data/glr.c: Now that yyrhs no longer exists as a global
2072 variable, rename local "rhs" variables into "yyrhs" for
2073 consistency.
2074
2075 2008-11-25 Akim Demaille <demaille@gostai.com>
2076
2077 Get rid of yyrhs and yyprhs in glr.c.
2078 * data/glr.c (yyrhs, yyprhs): Remove.
2079 Instead, use the state stack and yystos.
2080
2081 2008-11-25 Akim Demaille <demaille@gostai.com>
2082
2083 Flag glr tests.
2084 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): If glr, declare it
2085 as an Autotest keyword.
2086
2087 2008-11-25 Akim Demaille <demaille@gostai.com>
2088
2089 Prefer TESTSUITE_FLAGS.
2090 TESTSUITEFLAGS is barely readable.
2091
2092 * tests/local.mk (TESTSUITE_FLAGS): Default to $(TESTSUITEFLAGS)
2093 for backward compatibility.
2094 Use the former instead of the latter.
2095
2096 2008-11-25 Akim Demaille <demaille@gostai.com>
2097
2098 Get rid of yyrhs and yyprhs in larl1.java.
2099 * data/lalr1.java (yyrhs_, yyprhs_): Remove.
2100 (yy_reduce_print): Rather, use yystos_ and the state stack.
2101
2102 2008-11-25 Akim Demaille <demaille@gostai.com>
2103
2104 Formatting changes.
2105
2106 2008-11-25 Akim Demaille <demaille@gostai.com>
2107
2108 Get rid of yyrhs and yyprhs in yacc.c.
2109 They were used to get the symbol types, given a rule number, when
2110 displaying the top of the stack before a reduction. But the
2111 symbol type is available from the state stack. This has two be
2112 benefits: two tables less in the parser (making it smaller), and a
2113 more consistent use of the three stacks which will help to fuse
2114 them.
2115
2116 * data/yacc.c (yyprhs, yyrhs): Remove.
2117 (YY_REDUCE_PRINT): Pass yyssp to yy_reduce_print.
2118 (yy_reduce_print): Take yyssp as argument.
2119 Use it, together with yystos, to get the symbol type.
2120 * tests/regression.at (Web2c Report): Remove these tables from the
2121 expected output.
2122
2123 2008-11-25 Akim Demaille <demaille@gostai.com>
2124
2125 b4_tables_map.
2126 The point is to factor the generation of the tables across skeletons.
2127 This is language dependant.
2128
2129 * data/c.m4 (b4_comment_): New.
2130 Should be usable to define how to generate tables independently of
2131 the language.
2132 (b4_c_comment): New.
2133 (b4_comment): Bounce to b4_c_comment.
2134 Now support $2 = [PREFIX] for indentation.
2135 * data/lalr1.cc (b4_table_declare): Don't output a comment if
2136 there is no comment.
2137 Indent it properly when there is one.
2138 Output the ending semicolon.
2139 (b4_table_define): Space changes.
2140 Output the ending semicolon.
2141 (b4_tables_map): New.
2142 Use it twice instead of declaring and defining the (integral)
2143 tables by hand.
2144
2145 2008-11-25 Akim Demaille <demaille@gostai.com>
2146
2147 b4_table_declare.
2148 * data/lalr1.cc (b4_table_declare): New.
2149 Use it to declare the tables defined with b4_table_define.
2150 (b4_table_define): Declare a third arg to match b4_table_declare
2151 signature.
2152 Move all the comments around invocations of b4_table_define into
2153 the invocations itselves.
2154 Move things around to have the order for declarations and
2155 definitions.

2166 * data/bison.m4: here.
2167
2168 2008-11-21 Di-an Jan <dianj@freeshell.org>
2169
2170 Implement no-XXX arguments for --warnings, --report, --trace.

2184 * doc/bison.texinfo (-g, -x): Add space before argument.
2185 (Option Cross Key): Implement FIXME: listing directives also.
2186 * build-aux/cross-options.pl: Read from <STDIN> rather than <>.
2187 (Short Option): Special case -d. Put arguments inside @option.
2188 (Bison Directive): Add column, automatically extracted from
2189 src/scan-gram.l (actual name passed as the first argument)
2190 with special case for %define.
2191 * doc/local.mk (doc/cross-options.texi): Pass src/scan-gram.l
2192 to build-aux/cross-options.pl.
2193 * src/getargs.c (usage): Document limitations of cross-options.pl.
2194 * src/scan-gram.l: Likewise.

2300 Remove duplicate header inclusion.

2308
2309 Support parametric types.
2310
2311 There are two issues to handle: first scanning nested angle
2312 bracket pairs to support types such as std::pair< std::string,
2313 std::list<std::string> > >.
2314
2315 Another issue is to address idiosyncracies of C++: do not glue two
2316 closing angle brackets together (otherwise it's operator>>), and
2317 avoid sticking blindly a TYPE to the opening <, as it can result
2318 in '<:' which is a digraph for '['.
2319
2320 * src/scan-gram.l (brace_level): Rename as...
2321 (nesting): this.
2322 (SC_TAG): New.
2323 Implement support for complex tags.
2324 (tag): Accept
2325 , but not <.
2326 * data/lalr1.cc (b4_symbol_value, b4_symbol_value_template)
2327 (b4_symbol_variant): Leave space around types as parameters.
2328 * examples/variant.yy: Use nested template types and leading ::.
2329 * src/parse-gram.y (TYPE, TYPE_TAG_ANY, TYPE_TAG_NONE, type.opt):
2330 Rename as...
2331 (TAG, TAG_ANY, TAG_NONE, tag.opt): these.
2332 * tests/c++.at: Test parametric types.
2333
2334 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
2335
2336 Test token.prefix.
2337 This is not sufficient, but we test at least that the make_SYMBOL
2338 interface is not affected by token.prefix. A more general test
2339 will be implemented when the support of token.prefix is generalized
2340 to more skeletons.
2341
2342 * tests/c++.at: One more variant test, using token.prefix.
2343
2344 2008-11-15 Akim Demaille <akim@betelgeuse.gostai.ensta.fr>
2345
2346 Test the make_TOKEN interface.
2347 * tests/c++.at (AT_CHECK_VARIANTS): Require and use locations.
2348 Factor the common code in yylex.
2349 Use it to test "%define lex_symbol".

2359 location_type.
2360 Factor the common code in yylex.
2361
2362 2008-11-15 Akim Demaille <demaille@gostai.com>
2363
2364 Better error message.
2365 * bootstrap (find_tool): Fix the error message.
2366
2367 2008-11-15 Akim Demaille <demaille@gostai.com>

2382 comments for the license.

2415
2416 Move sc_tight_scope into maint.mk.
2417 It does not work, and I don't know how it was supposed to work: it
2418 seems to be looking for sources in the build tree. I just moved
2419 it at a better place, fixing it is still required.
2420
2421 * src/local.mk (echo): Remove.
2422 (sc_tight_scope): Move to...

2435 Prefix all the paths with src/.
2436 (AUTOMAKE_OPTIONS): Build object files in the sub dirs.
2437 (AM_CPPFLAGS): Find find in builddir/src.
2438 (YACC): Move the flags into...
2439 (AM_YFLAGS): here.
2440 * maint.mk (sc_tight_scope): Disable.
2441 It used to bounce to the version in src/Makefile.am which is now
2442 part of this very Makefile.
2443 * Makefile.am, configure.ac: Adjust.
2444 * src/scan-code-c.c, src/scan-code.l: We can no longer rely on
2445 include "..." to find files "here": we are no longer in src/, so
2446 qualify the includes with src/.
2447 * doc/Makefile.am (PREPATH): No longer include the top_builddir
2448 prefix.
2449 (.x.1): Adjust to be able to create src/foo from the top level
2450 Makefile, instead of going bounce to src/Makefile the creation of
2451 foo.
2452
2453 2008-11-15 Akim Demaille <demaille@gostai.com>
2454

2475
2476 Remove examples/local.mk.
2477 examples/calc++/Makefile.am might be interesting to keep as is, since
2478 it is an example in itself.
2479
2480 * examples/Makefile.am: Rename as...

2498 Provide convenience constructors for locations and positions.
2499 * data/location.cc (position::position): Accept file, line and
2500 column as arguments with default values.
2501 Always qualify initial line and column literals as unsigned.
2502 (location::location): Provide convenience constructors.
2503
2504 2008-11-15 Akim Demaille <demaille@gostai.com>
2505
2506 Instead of using make_symbol<TOK_FOO>, generate make_FOO for each
2507 token type.
2508 Using template buys us nothing, and makes it uselessly complex to
2509 construct a symbol. Besides, it could not be generalized to other
2510 languages, while make_FOO would work in C/Java etc.
2511
2512 * data/lalr1.cc (b4_symbol_): New.
2513 (b4_symbol): Use it.
2514 (b4_symbol_constructor_declaration_)
2515 (b4_symbol_constructor_definition_): Instead of generating
2516 specializations of an overloaded template function, just generate
2517 several functions whose names are forged from the token names
2518 without the token.prefix.
2519 (b4_symbol_constructor_declarations): Generate them for all the
2520 symbols, not just by class of symbol type, now that instead of
2521 specializing a function template by the token, we generate a
2522 function named after the token.
2523 (b4_symbol_constructor_specialization_)
2524 (b4_symbol_constructor_specializations): Remove.
2525 * etc/bench.pl.in: Adjust to this new API.
2526
2527 2008-11-13 Akim Demaille <demaille@gostai.com>
2528
2529 %define token.prefix.
2530 Provide a means to add a prefix to the name of the tokens as
2531 output in the generated files. Because of name clashes, it is
2532 good to have such a prefix such as TOK_ that protects from names
2533 such as EOF, FILE etc. But it clutters the grammar itself.
2534
2535 * data/bison.m4 (token.prefix): Empty by default.
2536 * data/c.m4 (b4_token_enum, b4_token_define): Use it.
2537 * data/lalr1.cc (b4_symbol): Ditto.
2538

2547 symbol::token.
2548 This allows the user to get the type of a token returned by yylex.
2549
2550 * data/lalr1.cc (symbol::token): New.
2551 (yytoknum_): Define when %define lex_symbol, independently of
2552 %debug.
2553 (yytoken_number_): Move into...
2554 (symbol::token): here, since that's the only use.
2555 The other one is YYPRINT which was not officially supported
2556 by lalr1.cc, and anyway it did not work since YYPRINT uses this
2557 array under a different name (yytoknum).

2573 yytranslate and yytoknum tables.
2574
2575 2008-11-13 Akim Demaille <demaille@gostai.com>
2576
2577 Define make_symbol in the header.
2578 To reach good performances these functions should be inlined (yet
2579 this is to measure precisely). To this end they must be available
2580 to the caller.
2581
2582 * data/lalr1.cc (b4_symbol_constructor_definition_): Qualify
2583 location_type with the class name.
2584 Since will now be output in the header, declare "inline".
2585 No longer use b4_symbol_constructor_specializations, but
2586 b4_symbol_constructor_definitions in the header.
2587 Don't call it in the *.cc file.
2588
2589 2008-11-13 Akim Demaille <demaille@gostai.com>
2590
2591 Define yytranslate in the header for lex_symbol.
2592 * data/lalr1.cc: Move the invocation of b4_yytranslate_definition
2593 into the header file when using %define lex_symbol.
2594 (yytranslate_): Declare inline.
2595
2596 2008-11-13 Akim Demaille <demaille@gostai.com>
2597
2598 Define the constructors of symbol_type in
2599 b4_symbol_constructor_definitions.
2600 The constructors are called by the make_symbol functions, which a
2601 forthcoming patch will move elsewhere. Hence the interest of
2602 putting them together.
2603
2604 The stack_symbol_type does not need to be moved, it is used only
2605 by the parser.
2606
2607 * data/lalr1.cc: Move symbol_type and symbol_base_type
2608 constructors into...
2609 (b4_symbol_constructor_definitions): here.
2610 Adjust.
2611
2612 2008-11-13 Akim Demaille <demaille@gostai.com>
2613
2614 Make it easier to move the definition of yytranslate_.
2615 Forthcoming changes will make it possible to use yytranslate_
2616 from outside the parser implementation file.
2617
2618 * data/lalr1.cc (b4_yytranslate_definition): New.
2619 Use it.
2620
2621 2008-11-13 Akim Demaille <demaille@gostai.com>
2622
2623 Remove useless class specification.
2624 * data/lalr1.cc (b4_symbol_constructor_specialization_): No need
2625 to refer to the class name to use a type defined by the class for
2626 arguments of member functions.
2627
2628 2008-11-13 Akim Demaille <demaille@gostai.com>
2629
2630 Finer input type for yytranslate.
2631 This patch is debatable: the tradition expects yylex to return an int
2632 which happens to correspond to token_number (which is an enum). This
2633 allows for instance to return characters (such as '*' etc.). But this
2634 goes against the stronger typing I am trying to have with the new
2635 lex interface which return a symbol_type. So in this case, feed
2636 yytranslate_ with a token_type.
2637
2638 * data/lalr1.cc (yytranslate_): When in %define lex-symbol,
2639 expect a token_type.
2640
2641 2008-11-13 Akim Demaille <demaille@gostai.com>
2642
2643 Honor lex-params in %define lex_symbol mode.
2644 * data/lalr1.cc: Use b4_lex_param.
2645
2646 2008-11-13 Akim Demaille <demaille@gostai.com>
2647
2648 Simplify names.
2649 * src/output.c (symbol_definitions_output): Rename symbol
2650 attributes type_name and has_type_name as type and has_type.
2651 * data/lalr1.cc: Adjust uses.
2652
2653 2008-11-13 Akim Demaille <demaille@gostai.com>
2654
2655 Use b4_type_names for the union type.
2656 The union used to compute the size of the variant used to iterate
2657 over the type of all the symbols, with a lot of redundancy. Now
2658 iterate over the lists of symbols having the same type-name.
2659
2660 * data/lalr1.cc (b4_char_sizeof_): New.
2661 (b4_char_sizeof): Use it.
2662 Adjust to be called with a list of numbers instead of a single
2663 number.
2664 Adjust its caller for new-line issues.
2665
2666 2008-11-13 Akim Demaille <demaille@gostai.com>
2667
2668 Define the "identifier" of a symbol.
2669 Symbols may have several string representations, for instance if
2670 they have an alias. What I call its "id" is a string that can be
2671 used as an identifier. May not exist.
2672
2673 Currently the symbols which have the "tag_is_id" flag set are
2674 those that don't have an alias. Look harder for the id.
2675
2676 * src/output.c (is_identifier): Move to...
2677 * src/symtab.c (is_identifier): here.
2678 * src/symtab.h, src/symtab.c (symbol_id_get): New.
2679 * src/output.c (symbol_definitions_output): Use it to define "id"
2680 and "has_id".
2681 Remove the definition of "tag_is_id".
2682 * data/lalr1.cc: Use the "id" and "has_id" whereever "tag" and
2683 "tag_is_id" were used to produce code.
2684 We still use "tag" for documentation.

2691 * tests/c++.at (AT_CHECK_VARIANTS): No longer use the locations.
2692 (AT_CHECK_NAMESPACE): Check the use of locations.
2693 * tests/calc.at (_AT_DATA_CALC_Y): Adjust to be usable with or
2694 without locations with lalr1.cc.
2695 Test these cases.
2696 * tests/output.at: Check lalr1.cc with and without location
2697 support.

2774 * data/lalr1.cc (parse::yychar): Replace by...
2775 (parse::yyempty): this.
2776
2777 2008-11-11 Akim Demaille <demaille@gostai.com>
2778
2779 Factor the tables.
2780 * TODO: New item.
2781
2782 2008-11-11 Akim Demaille <demaille@gostai.com>
2783
2784 Let yytranslate handle the eof case.
2785 * data/lalr1.cc (yytranslate_): Handle the EOF case.
2786 Adjust callers.
2787 No longer expect yychar to be equal to yyeof_, rather, test the
2788 lookahead's (translated) kind.
2789
2790 2008-11-11 Akim Demaille <demaille@gostai.com>
2791
2792 yychar cannot be empty in yyerrlab.
2793 * TODO (yychar == yyempty_): New.
2794 * data/lalr1.cc: Remove the handling of this case.
2795 This eases forthcoming changes related to yychar and yytranslate.
2796
2797 2008-11-11 Akim Demaille <demaille@gostai.com>
2798
2799 Bench: syntactic sugar for %define/#define.
2800 * etc/bench.pl.in (parse_dirs): Support %d and #d with arguments.
2801 (&bench_push_parser, bench_variant_parser): Use this feature.
2802 (&eat): New.
2803 Use it.
2804
2805 2008-11-11 Akim Demaille <demaille@gostai.com>
2806
2807 Less memory pressure on the "list" bench.
2808 * etc/bench.pl.in (generate_grammar_list): Do not accumulate all
2809 the values, to limit memory pressure.
2810
2811 2008-11-11 Akim Demaille <demaille@gostai.com>
2812
2813 Introduce make_symbol.
2814 make_symbol provides a means to construct a full symbol (kind,
2815 value, location) in a single shot. It is meant to be a Symbol
2816 constructor, parameterized by the symbol kind so that overloading
2817 would prevent incorrect kind/value pairs. Unfortunately
2818 parameterized constructors do not work well in C++ (unless the
2819 parameter also appears as an argument, which is not acceptable),
2820 hence the use of a function instead of a constructor.
2821
2822 * data/lalr1.cc (b4_symbol_constructor_declaration_)
2823 (b4_symbol_constructor_declarations)
2824 (b4_symbol_constructor_specialization_)
2825 (b4_symbol_constructor_specializations)
2826 (b4_symbol_constructor_definition_)
2827 (b4_symbol_constructor_definitions): New.
2828 Use them where appropriate to generate declaration, declaration of
2829 the specializations, and implementations of the templated
2830 overloaded function "make_symbol".
2831 (variant::variant): Always define a default ctor.
2832 Also provide a copy ctor.
2833 (symbol_base_type, symbol_type): New ctor overloads for value-less
2834 symbols.
2835 (symbol_type): Now public, so that functions such as yylex can use
2836 it.
2837
2838 2008-11-11 Akim Demaille <demaille@gostai.com>
2839
2840 Inform m4 whether a tag is a valid id.
2841 * src/output.c (is_identifier): New.
2842 (symbol_definitions_output): Use it to define tag_is_id.
2843 But maybe this should be done at m4 level?
2844
2845 2008-11-11 Akim Demaille <demaille@gostai.com>
2846
2847 Test 214 was failing: it greps with a pattern containing [ ]*
2848 which obviously meant to catch spaces and tabs, but contained only
2849 spaces. Tabulations in sources are a nuisance, so to simplify the
2850 matter, get rid of all the tabulations in the Java sources. The
2851 other skeletons will be treated equally later.
2852
2853 * data/java.m4, data/lalr1.java: Untabify.
2854 * tests/java.at: Simplify AT_CHECK_JAVA_GREP invocations:
2855 tabulations are no longer generated.
2856
2857 2008-11-11 Paolo Bonzini <bonzini@gnu.org>
2858
2859 * bootstrap.conf: Replace m4/warning.m4 with warnings module.
2860 * configure.ac: Adjust usage.
2861 * lib/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
2862 * src/Makefile.am: Replace $(WARNING_CFLAGS) with $(WARN_CFLAGS).
2863 * tests/atlocal.in: Replace $(WARNING_*FLAGS) with $(WARN_*FLAGS).
2864
2865 2008-11-10 Di-an Jan <dianj@freeshell.org>
2866
2867 Workaround Java's ``code too large'' problem for parser tables
2868 in most cases, by using one function per initialization.
2869 * data/java.m4 (b4_typed_parser_table, b4_integral_parser_table): New.
2870 * data/lalr1.java (yypact_, yydefact_, yypgoto_, yydefgoto_,
2871 yytable_, yycheck_, yystos_, yytoken_number_, yyr1_, yyr2_, yyrhs_
2872 yyprhs_, yyrline_, yytranslate_table_): Use b4_integral_parser_table.

2878
2879 * NEWS: Document them.
2880
2881 General Java skeleton improvements.
2882 * configure.ac (gt_JAVACOMP): Request target of 1.4, which allows

2890 * data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
2891 which marks the end of user code with appropriate syncline, like all
2892 the other skeletons.
2893 (b4_user_post_prologue): Add. Don't silently drop.
2894 (yylex): Remove.

2916
2917 Move constants for token names to Lexer interface.
2918 * data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
2919 * data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
2920 (parse): Qualify EOF to Lexer.EOF.
2921 * doc/bison.texinfo (Java Parser Interface): Move documentation of
2922 EOF and token names to Java Lexer Interface.
2923 * tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
2924
2925 Make yyerror public.
2926 * data/lalr1.java (Lexer.yyerror): Use longer parameter name.
2927 (yyerror): Change to public. Add Javadoc comments. Use longer
2928 parameter names. Make the body rather than the declarator
2929 conditional on %locations.

2942
2943 2008-11-10 Akim Demaille <demaille@gostai.com>
2944
2945 Update TODO.
2946 * TODO (-D): is implemented.
2947 (associativity): Same precedence must have the same associativity.
2948 For instance, how can a * b / c be parsed if * is %left and / is
2949 %right?
2950 (YYERRORCODE, YYFAIL, YYBACKUP): New.

2959 * src/output.c (type_names_output): Document all the symbols,
2960 including those that don't have a type-name.
2961 (symbol_definitions_output): Define "is_token" and
2962 "has_type_name".
2963 * data/lalr1.cc (b4_type_action_): Skip symbols that have an empty
2964 type-name, now that they are defined too in b4_type_names.
2965
2966 2008-11-10 Akim Demaille <demaille@gostai.com>
2967
2968 Regen.
2969
2970 2008-11-10 Akim Demaille <demaille@gostai.com>
2971
2972 Make parser::yytranslate static.
2973 Small speedup (1%) on the list grammar. And makes yytranslate_
2974 available in non member functions.
2975
2976 * data/lalr1.cc (yytranslate_): Does not need to be a instance
2977 function.
2978
2979 2008-11-10 Akim Demaille <demaille@gostai.com>
2980
2981 Avoid trailing spaces.
2982 * data/c.m4: b4_comment(TEXT): Don't indent empty lines.
2983 * data/lalr1.cc: Don't indent before rule and symbol actions, as
2984 they can be empty, and anyway this incorrectly indents the first
2985 action.
2986

2993 Use "enum" for integral constants.
2994 This is just nicer to read, I observed no speedup.

2997 (yterror_, yyerrcode_, yyntokens_): Define as members of an enum.

3032
3033 2008-11-10 Akim Demaille <demaille@gostai.com>
3034
3035 Change the handling of the symbols in the skeletons.
3036 Before we were using tables which lines were the symbols and which
3037 columns were things like number, tag, type-name etc. It is was
3038 difficult to extend: each time a column was added, all the numbers had
3039 to be updated (you asked for colon $2, not for "tag"). Also, it was
3040 hard to filter these tables when only a subset of the symbols (say the
3041 tokens, or the nterms, or the tokens that have and external number
3042 *and* a type-name) was of interest.
3043
3044 Now instead of monolithic tables, we define one macro per cell. For
3045 instance "b4_symbol(0, tag)" is a macro name which contents is
3046 self-decriptive. The macro "b4_symbol" provides easier access to
3047 these cells.
3048
3049 * src/output.c (type_names_output): Remove.
3050 (symbol_numbers_output, symbol_definitions_output): New.
3051 (muscles_output): Call them.
3052 (prepare_symbols): Define b4_symbols_number.
3053

3055

3057 * src/getargs.h, src/getargs.c (trace_muscle): New.

3084 an argument.

3093 2008-11-10 Akim Demaille <demaille@gostai.com>
3094
3095 Add %precedence support.
3096 Unfortunately it is not possible to reuse the %prec directive. This
3097 is because to please POSIX, we do not require to end the rules with a
3098 semicolon. As a result,
3099
3100 foo: bar %prec baz
3101
3102 is ambiguous: either a rule which precedence is that of baz, or a rule,
3103 and then a declaration of the precedence of the token baz.
3104
3105 * doc/bison.texinfo: Document %precedence.
3106 (Precedence Only): New.
3107 * src/assoc.h, src/assoc.c (precedence_assoc): New.

3253 fresh error_token.

3349
3350 Handle more general types of option arguments.
3351 * build-aux/cross-options.pl: The argument ends at the first
3352 space, not the first non-symbol character.
3353 Use @var for each word appearing the argument description.
3354
3355 2008-11-07 Akim Demaille <demaille@gostai.com>

3362
3363 2008-11-07 Akim Demaille <demaille@gostai.com>
3364
3365 Add "%define assert" to variants.
3366 This is used to help the user catch cases where some value gets
3367 ovewritten by a new one. This should not happen, as this will
3368 probably leak.
3369
3370 Unfortunately this uncovered a bug in the C++ parser itself: the
3371 lookahead value was not destroyed between two calls to yylex. For
3372 instance if the previous lookahead was a std::string, and then an int,
3373 then the value of the std::string was correctly taken (i.e., the
3374 lookahead was now an empty string), but std::string structure itself
3375 was not reclaimed.
3376
3377 This is now done in variant::build(other&) (which is used to take the
3378 value of the lookahead): other is not only stolen from its value, it
3379 is also destroyed. This incurs a new performance penalty of a few
3380 percent, and union becomes faster again.
3381
3382 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
3383 (b4_variant_if): New.
3384 (variant::built): New.
3385 Use it whereever the status of the variant changes.
3386 * etc/bench.pl.in: Check the penalty of %define assert.
3387
3388 2008-11-07 Akim Demaille <demaille@gostai.com>
3389
3390 Use "%define variant" in bench.pl.
3391 * etc/bench.pl.in: No longer use the pseudo directive %variants,
3392 just use %define variants.
3393
3394 2008-11-07 Akim Demaille <demaille@gostai.com>

3660
3661 Fuse the three stacks into a single one.
3662
3663 In order to make it easy to perform benchmarks to ensure that
3664 there are no performance loss, lalr1.cc is forked into
3665 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
3666 lalr1.cc.
3667
3668 Meanwhile, to make sure that lalr1-fusion.cc is correctly
3669 exercized by the test suite, the user must install a symbolic link
3670 from lalr1.cc to it.
3671
3672 Instead of having three stacks (state, value, location), use a
3673 stack of triples. This considerably simplifies the code (and it
3674 will be easier not to require locations as currently does the C++
3675 parser), and also gives a 10% speedup according to
3676 etc/bench (probably mainly since memory allocation is done once
3677 instead of three times).
3678
3679 Another motivation is to make it easier to destruct properly
3680 semantic values: now that they are bound to their state (hence
3681 symbol type) it will be easier to call the appropriate destructor.
3682
3683 These changes should probably benefit the C parser too.
3684
3685 * data/lalr1.cc: Copy as...
3686 * data/lalr1-fusion.cc: this new file.
3687 (b4_rhs_value, b4_rhs_location): New definitions overriding those
3688 from c++.m4.
3689 (state_stack_type, semantic_stack_type, location_stack_type)
3690 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
3691 (data_type, stack_type, yystack_): New.
3692 (YYLLOC_DEFAULT, yypush_): Adjust.
3693 (yyerror_range): Now based on data_type, not location_type.
3694
3695 2008-11-03 Akim Demaille <demaille@gostai.com>
3696
3697 Push the state, value, and location at the same time.
3698 This is needed to prepare a forthcoming patch that fuses the three
3699 stacks into one.
3700
3701 * data/lalr1.cc (parser::yypush_): New.
3702 (parser::yynewstate): Change the semantics: instead of arriving to
3703 this label when value and location have been pushed, but yystate
3704 is to be pushed on the state stack, now the three of them must
3705 have been pushed before. yystate still must be the new state.
3706 This allows to use yypush_ everywhere instead of individual
3707 handling of the stacks.
3708
3709 2008-11-03 Akim Demaille <demaille@gostai.com>
3710
3711 Prefer references to pointers.
3712 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
3713 definition to use references instead of pointers.
3714 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
3715 Take the value and location as references.
3716 Adjust callers.
3717
3718 2008-11-03 Akim Demaille <demaille@gostai.com>
3719

3727
3728 Use variants to support objects as semantic values.
3729 This patch was inspired by work by Michiel De Wilde. But he used
3730 Boost variants which (i) requires Boost on the user side, (ii) is
3731 slow, and (iii) has useless overhead (the parser knows the type of
3732 the semantic value there is no reason to duplicate this
3733 information as Boost.Variants do).
3734
3735 This implementation reserves a buffer large enough to store the
3736 largest objects. yy::variant implements this buffer. It was
3737 implemented with Quentin Hocquet.
3738
3739 * src/output.c (type_names_output): New.
3740 (output_skeleton): Invoke it.
3741 * data/c++.m4 (b4_variant_if): New.

3744 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
3745 (b4_char_sizeof, yy::variant): New.
3746 (parser::parse): If variants are requested, define
3747 parser::union_type, parser::variant, change the definition of
3748 semantic_type, construct $$ before running the user action instead
3749 of performing a default $$ = $1.
3750 * examples/variant.yy: New.
3751 Based on an example by Michiel De Wilde.
3752
3753 2008-11-03 Akim Demaille <demaille@gostai.com>
3754
3755 Parameterize the extraction of semantic values.
3756 To make future changes easier, no longer rely on ".TYPE" being the
3757 way to get a semantic value.
3758
3759 * data/c.m4 (b4_symbol_value): New.
3760 Use it.
3761 * data/c++.m4, data/yacc.c: Use it.
3762 * data/glr.c: Use b4_symbol_value.
3763 (b4_rhs_data): New.
3764 Use it.
3765
3766 2008-11-03 Akim Demaille <demaille@gostai.com>
3767
3768 Prepare easier M4 changes.

3790
3791 Say %language is experimental.

3870 Always put auxiliary code files in the same dir as other output files.
3871 * src/files.c (compute_file_name_parts): When the user specifies
3872 --output but not --file-prefix, extract the directory prefix from the
3873 file prefix not from the grammar file name. This affects the location
3874 of files like location.hh generated by the C++ skeleton. The includes

4026 declares it.
4027
4028 2008-08-07 Joel E. Denny <jdenny@ces.clemson.edu>
4029
4030 Keep .version and PACKAGE_VERSION in sync.
4031 * Makefile.am ($(top_srcdir)/.version): Declare configure as a
4032 dependency, and add comments justifying this in more detail. Discussed

4108
4109 2008-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
4110
4111 Fix dependence on computed configure variables.
4112 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not
4113 $(top_srcdir)/configure.ac so that changes to computed variables, such

4138 .prev-version, and .version.
4139 * NEWS (2.3b+): Rename to...
4140 (?.?): ... this because we're dropping the "+" version naming scheme,
4141 but, in general, we still can't be sure of our next release name.
4142 * bootstrap: Add a quick hack to remove from .gitignore the
4143 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
4144 entry. This should really be fixed in gnulib instead.

4180 .gitignore entries before passing them to insert_sorted_if_absent.
4181 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
4182 .cvsignore files are maintained even though Bison developers run
4183 bootstrap while using Git.
4184 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
4185 unneeded by Bison.
4186 (gnulib): Add.
4187 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
4188 unneeded. Reported by Eric Blake.
4189 * lib/.gitignore (/*~): Add.

4269
4270 Revert prior patch, by working around autoconf regression.
4271 * tests/output.at (m4_expand): Add workaround for autoconf 2.62.
4272 ("Output file name: ("): Uncomment test.
4273 ("Output file name: )"): Likewise.
4274 Based on an idea from Noah Misch.
4275
4276 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
4277
4278 Work-around an Autoconf 2.62 AT_SETUP bug that was not present in
4279 2.61. Reported by Juan Manuel Guerrero at
4280 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
4281 * tests/output.at ("Output file name: ("): Comment out test case for
4282 now.
4283 ("Output file name: )"): Likewise.
4284
4285 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

4288 succeeds.
4289
4290 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
4291
4292 Update to the current gnulib CVS repository, and fix trigraph handling
4293 in Bison.
4294 * bootstrap: Update gnulib CVS repository URL.
4295 (symlink_to_dir): Encapsulate the code that guarantees the destination
4296 directory exists into...
4297 (check_dst_dir): ... this new function, and...
4298 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
4299 fail when copying files into lib/uniwidth/.
4300 * src/output.c (prepare_symbols): When writing yytname muscles, where
4301 symbol names will be encoded in C-string literals, tell quotearg to
4302 escape trigraphs. This used to be the default in gnulib.
4303 * tests/regression.at (Token definitions): Because of the change in
4304 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
4305 escapes trigraphs in symbol names. Thus, yytname no longer has
4306 trigraphs unnecessarily doubly escaped. Update test case output.
4307 Extend test case to be sure Bison's own error messages will no longer
4308 have trigraphs in symbol names unnecessarily escaped once.
4309

4323 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
4324 consistency. Update the -g and -x entries now that they take
4325 arguments. Use brackets to indicate optional arguments.
4326 * src/getargs.c (usage): Explain the relationship between arguments of
4327 long and short options more completely. Document --defines and -d
4328 separately since the former takes an argument but, for POSIX Yacc, the
4329 latter does not.

4343
4344 * src/getargs.c (short_options): Split and sort for readability.
4345 -g and -x take optional arguments, just like their long options.
4346 * build-aux/cross-options.pl: Use /x to make the regexp easier to
4347 understand.
4348 Fix the handling of $opt which resulted in all the argument to be
4349 considered as optional.
4350
4351 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

4982 * data/location.cc (b4_namespace): Likewise.
4983 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
4984 inside a new table in the general %define entry. Document `%define
4985 namespace' there as well. Point the %name-prefix entry to it since it
4986 explains it more completely in the case of C++.
4987 (C++ Bison Interface): Mention `%define namespace' instead of
4988 %name-prefix.
4989 (Table of Symbols): Remove the `%define push_pull' entry. The %define
4990 entry suffices.
4991 * tests/c++.at (Relative namespace references): New test case.
4992 (Absolute namespace references): New test case.
4993 (Syntactically invalid namespace references): New test case.
4994 * tests/input.at (C++ namespace reference errors): New test case.
4995
4996 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>

5003 (b4_percent_define_default): Record defining location as line 1 rather
5004 than 0 for the sake of synchronizing #line's, and define
5005 b4_percent_define_syncline(VARIABLE).
5006 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
5007 * src/muscle_tab.c (muscle_syncline_grow): New.
5008 (muscle_code_grow): Use muscle_syncline_grow.
5009 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and

5011 (muscle_percent_define_get_loc): New.
5012 (muscle_percent_define_get_syncline): New.
5013 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
5014 remove some unused variables.
5015 (muscle_percent_define_default): Record defining location as line 1
5016 rather than 0 for the sake of synchronizing #line's, and define
5017 b4_percent_define_syncline(VARIABLE).
5018 (muscle_percent_define_check_values): Use
5019 muscle_percent_define_get_loc.
5020 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
5021 (muscle_percent_define_get_syncline): Prototype.

5025 b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
5026
5027 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
5028
5029 Fix some error-reporting macro bugs.
5030 * data/bison.m4 (b4_cat): New.
5031 (b4_error, b4_error_at): Use b4_cat to send error directives directly
5032 to stdout so they don't become arguments to other macros. Update
5033 comments and add examples.
5034 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
5035 add examples.
5036 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
5037 after printing the error directive so that M4 doesn't report subsequent
5038 problems that are induced by this problem.
5039 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
5040 instead of just in them. Recognize @\n in both places. Both expand to
5041 the empty string. Needed by b4_cat.
5042 * tests/skeletons.at (Complaining during macro argument expansion):
5043 New test case.
5044 (Fatal errors make M4 exit immediately): New test case.
5045

5054 computation from here...
5055 (prepare): ... and from here...
5056 (compute_pkgdatadir): ... into this new function.
5057 * src/output.h (compute_pkgdatadir): Prototype.
5058
5059 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
5060
5061 * src/print-xml.c (escape_bufs): New static global variable

5073 Pull Parser Function, Parser Create Function, Parser Delete Function):
5074 Update declarations.
5075 (Decl Summary, Table of Symbols): Replace %push-parser and

5079 definitions...
5080 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
5081 definitions...
5082 * data/push.c: ... to here and compute them from the value of the
5083 %define variable push_pull.
5084 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
5085 parsing requests here...
5086 * data/yacc.c: ... hack this to switch to push.c any time
5087 b4_use_push_pull_flag or the %define variable push_pull is set. This
5088 will go away when we mv push.c yacc.c.
5089 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
5090 push parsing is not supported since unused %define variables are
5091 reported anyway.
5092 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
5093 * src/muscle_tab.h (muscle_percent_define_check_values): Update

5130 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
5131
5132 Pacify ./configure --enable-gcc-warnings.
5133 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
5134 `char const *' instead of `char *'.
5135 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
5136 local variable `sep'.
5137
5138 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
5139
5140 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
5141 elsewhere.
5142 * src/print-xml.c: Prefer "const" after types; that's more consistent.
5143 (xml_printf): Indent just 1 space for level.
5144 (e_char, xlate_char): Remove.
5145 (xml_escape_string): Rewrite to avoid undefined behavior (used
5146 storage that was freed from the stack).
5147 (xml_escape_n): Don't bother checking for subscript error.

5215
5216 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
5217
5218 In impure push mode, don't allow more than one yypstate to be allocated
5219 since multiple impure parsers would corrupt yynerrs.
5220 * data/push.c (yypstate_allocated): New static global variable
5221 initialized to 0.
5222 (yypull_parse): If yypstate_new returns 0, don't report it as memory
5223 exhaustion if yypstate_allocated is 1, but still return 2.
5224 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
5225 already 1. Otherwise, set it to 1.

5299 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
5300
5301 Get rid of broken %no-parser, -n, and --no-parser implementation and
5302 documentation.
5303 * TODO: Don't mention them.
5304 * doc/bison.1: Likewise.
5305 * doc/bison.texinfo (Decl Summary): Likewise.
5306 (Bison Options): Likewise.
5307 (Option Cross Key): Likewise.
5308 * src/getargs.c (no_parser_flag): Remove global variable.
5309 (usage): Don't print description of -n and --no-parser.
5310 (long_options): Remove --no-parser entry here.
5311 (getargs): Remove -n case in the switch here.
5312 * src/getargs.h (no_parser_flag): Remove extern.
5313 * tests/regression.at (Web2c Actions): Remove comment that mentions
5314 --no-parser.
5315
5316 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
5317
5318 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
5319 name user variables starting with `yy'. Just pass NULL instead of a
5320 dummy local &yylval to yypush_parse.
5321 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
5322 starting with `yy'.
5323
5324 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
5325
5326 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
5327 true since it's then always used regardless of whether yyoverflow is
5328 defined. Reported by Christian Burger at
5329 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
5330 * THANKS: Add Christian Burger.
5331
5332 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
5333 node names: say "Decl Summary" not "Bison Declaration Summary".
5334
5335 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
5336
5337 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
5338 determine whether this function has already complained about an invalid
5339 value for a %define boolean variable, don't check whether Bison has
5340 ever examined the value. As written, the check was a tautology.
5341 Instead, record and check for this complaint using a separate muscle.
5342
5343 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
5344
5345 Fix push parsing memory leak reported by Brandon Lucia at
5346 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
5347 * THANKS: Add Brandon Lucia.
5348 * data/push.c (yypstate_delete): Free the stack if it was reallocated
5349 but the parse never completed and thus freed it.
5350 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
5351 * tests/testsuite.at: Include push.at.
5352 * test/push.at: New.
5353 (Push Parsing: Memory Leak for Early Deletion): New test case.
5354
5355 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
5356
5357 Improve handling of multiple S/R conflicts in the same state and of S/R
5358 conflicts involving multiple reductions.
5359 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
5360 set for a state here or Bison will abort if it is reassigned on a
5361 later conflicted reduction in the same state.
5362 Similarly, don't finalize and assign the solved conflicts report here
5363 or it will be lost if it is reassigned on a later conflicted reduction
5364 in the same state.
5365 (set_conflicts): Instead, assign them both here after all S/R conflicts
5366 in the state have been fully examined.
5367 * src/print.c (shift_set): Rename to...
5368 (no_reduce_set): ... this.
5369 (print_reductions): Update for rename, and add %nonassoc error action
5370 tokens to no_reduce_set so that, when printing the first remaining
5371 reduction on an error action token, the reduction is enclosed in
5372 brackets.
5373 (print_results): Update for rename.
5374 * tests/conflicts.at (Solved conflicts report for multiple reductions
5375 in a state): New test case.
5376 (%nonassoc error actions for multiple reductions in a state): New test
5377 case.
5378
5379 * src/main.c (main): Don't depend on C99 features.
5380
5381 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
5382
5383 * build-aux/.cvsignore: Add compile.
5384 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
5385 uniwidth.
5386
5387 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
5388
5389 * bootstrap (slurp): Create target directories that don't exist.
5390 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
5391
5392 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5393
5394 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
5395 than item number.
5396 * closure.c (closure): Likewise.
5397 * state.h (reductions): Comment sorting of rules.
5398 (state): Comment sorting of items.
5399
5400 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
5401
5402 Fix C++ test cases after recent Gnulib changes. Discussed starting at
5403 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
5404 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
5405 definition in order to avoid Gnulib headers since we don't use config.h
5406 here.
5407 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
5408 rather than AT_DATA so that config.h is included.
5409
5410 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
5411
5412 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
5413 instead of fprintf. Guard these functions with #if YYDEBUG instead of
5414 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
5415 and so that YYFPRINTF is guaranteed to be defined here.
5416
5417 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5418
5419 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
5420 with...
5421 (muscle_percent_define_check_values): ... this more helpful function.
5422 Again, it's not used yet, but it will be.
5423 * src/muscle_tab.h: Likewise.
5424
5425 Improve some comments in parser table construction.
5426 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
5427 (generate_states): Don't mention ruleset, which is internal to closure.
5428 * src/closure.c (closure): Explain sorting of core and itemset, which
5429 is required for this function to behave correctly.
5430 * src/closure.h (closure): Mention sorting.
5431
5432 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
5433
5434 * src/lalr.c (state_lookahead_tokens_count): For code readability,
5435 move the check for disabled transitions to an aver since conflict
5436 resolution hasn't happened yet.
5437
5438 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
5439 labels a state as inconsistent just because it has error transitions.
5440 The original form of this check appeared in revision 1.1 of lalr.c,
5441 which was committed on 1991-12-21. Now (at least), changing the
5442 consistency label on such a state appears to have no useful effect in
5443 any of the places it is examined, which I enumerate below. The key
5444 point to understanding each item in this enumeration is that a state
5445 with an error transition is labelled consistent in the first place only
5446 if it has no rules, so the check cannot matter for states that have
5447 rules. (1) Labelling a state as inconsistent will cause set_conflicts
5448 to try to identify its conflicts, and a state must have *rules* to have
5449 conflicts. (2) Labelling a state as inconsistent will affect how
5450 action_row sets the default *rule* for the state. (3) Labelling a
5451 state as inconsistent will cause build_relations to add lookback edges
5452 to *rules* in that state.
5453 * src/state.h (struct state): Word the comment for member consistent
5454 more carefully.
5455
5456 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
5457
5458 Don't depend on C99 features.
5459 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
5460 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
5461 * src/reader.c (check_and_convert_grammar): Fix for-loop.
5462 * src/state.c (state_mark_reachable_states): Fix for-loop.
5463 (state_remove_unreachable_states): Fix for-loop.
5464
5465 Don't widen struct state with member reachable just to temporarily
5466 record reachability. Instead, use a local bitset.
5467 * src/state.h (struct state): Remove member.
5468 * src/state.c (state_new): Don't initialize it.
5469 (state_mark_reachable_states): Rename to...
5470 (state_record_reachable_states): ... this, and use bitset.
5471 (state_remove_unreachable_states): Use bitset.
5472
5473 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
5474
5475 * src/Makefile.am (yacc): Quote target action commands properly so
5476 that the yacc script isn't corrupt. Reported by Hans Aberg at
5477 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
5478
5479 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
5480 the case of pure parsers. Reported by Frans Englich at
5481 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
5482 * THANKS: Add Frans Englich.
5483
5484 * NEWS (2.3a+): In the %code entry, reference section `Bison
5485 Declaration Summary' from the manual now since the %code summary has
5486 moved there.
5487 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
5488 in the rules section must be terminated by semicolons.
5489
5490 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
5491
5492 Extend the front-end API for %define variables to more completely
5493 mirror the back-end. This will be useful in the future.
5494 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
5495 Update comments to mention the new front-end counterparts of these
5496 macros.

5504 muscle_percent_define_get to mimic the b4_percent_define_flag_if
5505 implementation more closely.
5506 (muscle_percent_define_invalid_value): New function.
5507 * src/muscle_tab.h (muscle_percent_define_get,
5508 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
5509 Prototype.
5510
5511 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
5512
5513 * NEWS (2.3a+): Mention yesterday's state-removal change.
5514 (2.3a): Remove the %language entry, which was added after 2.3a.
5515 * src/LR0.c, src/closure.c, src/closure.h, src/conflicts.c,
5516 src/conflicts.h, src/lalr.c, src/lalr.h, src/print.c,
5517 src/print_graph.c, src/state.c, src/state.h, tests/conflicts.at,
5518 tests/existing.at: Update copyright date.
5519
5520 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
5521
5522 If conflict resolution makes states unreachable, remove those states,
5523 report rules that are then unused, and don't report conflicts in those
5524 states.
5525 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
5526 New global function.
5527 * src/lalr.c, src/lalr.h (lalr_update_state_numbers): New global
5528 function.

5534 (state_remove_unreachable_states): New global function.
5535 * src/state.h (struct state): Add member bool reachable.
5536 (state_remove_unreachable_states): Prototype.
5537 * tests/conflicts.at (Unreachable States After Conflict Resolution):
5538 New test case.
5539 * tests/existing.at (GNU pic Grammar): Update test case output now that
5540 an unused rule is discovered.
5541
5542 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
5543
5544 Minor code cleanup in parser table construction.
5545 * src/LR0.c (new_itemsets): Use item_number_is_symbol_number.
5546 (new_itemsets, save_reductions): Update for rename to nitemset.
5547 * src/closure.c (nritemset): Rename to...
5548 (nitemset): ... this since the "r" appears to meaningless and isn't
5549 used in the comments.
5550 (closure): Update for rename.
5551 * src/closure.h (nritemset): Update extern to...
5552 (nitemset): ... this.
5553 * src/lalr.c (LA): Fix a typo in comments.
5554 * src/print.c (print_core): Update for rename to nitemset.
5555 * src/print_graph.c (print_graph): Likewise.
5556 * src/state.h: Fix some typos in header comments.
5557
5558 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
5559
5560 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
5561 still sticks to ASCII. Sorry!
5562
5563 * README-hacking: New file, taken mostly from coreutils, with changes
5564 for Bison. Contains much of the contents of:
5565 * README-cvs: Remove.
5566 * bootstrap: Sync from gnulib.
5567 * build-aux/.cvsignore: Remove *.t, mkinstalldirs.

5611
5612 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5613
5614 DJGPP spefic issue. Inhibit the use of disallowed characters for
5615 file name genertion on Win98, WinXP, etc. These are |<>":?*\
5616 and concern testsuite case 46.
5617 * Makefile.am: djgpp/testsuite.sed added to EXTRA_DIST
5618 * djgpp/testsuite.sed: Inhibit the use of disallowed characters.
5619 * djgpp/config.bat: Inhibit the use of disallowed characters.
5620
5621 2007-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5622
5623 Miscellaneous %define and %code cleanup.
5624 * data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
5625 values are interpreted.
5626 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
5627 documentation a little more.
5628 * src/muscle_tab.c (MUSCLE_USER_NAME_CONVERT,
5629 muscle_percent_define_insert, muscle_percent_code_grow): New
5630 functions/macros.
5631 * src/muscle_tab.h (muscle_percent_define_insert,
5632 muscle_percent_code_grow): Prototype.
5633 * src/parse-gram.y (prologue_declaration): Use
5634 muscle_percent_define_insert and muscle_percent_code_grow when parsing
5635 %define and %code directives.
5636
5637 Make it easy to share %define boolean variables between the front-end
5638 and back-end. Though not used yet, this will be useful in the future.
5639 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
5640 Bison uses of names rather than just skeleton uses of names.
5641 (b4_percent_define_get, b4_percent_define_ifdef): Rename
5642 b4_percent_define_skeleton_variables(VARIABLE) to
5643 b4_percent_define_bison_variables(VARIABLE).

5649 muscle_percent_define_default): New functions mimicking
5650 b4_percent_define_flag_if and b4_percent_define_default.
5651
5652 For %define variables, report locations for invalid values and
5653 redefinitions.
5654 * data/bison.m4 (b4_percent_define_flag_if): Read
5655 b4_percent_define_loc(VARIABLE) to report the location of an invalid
5656 value for VARIABLE.
5657 (b4_percent_define_default): Save a special location in
5658 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
5659 must later be reported as invalid.
5660 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
5661 functions.
5662 (muscle_percent_define_insert): Record the location of VARIABLE in
5663 muscle percent_define_loc(VARIABLE), and use it to report the previous
5664 location for a redefinition.
5665 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
5666 (muscle_percent_define_default): Update like b4_percent_define_default.
5667 (muscle_grow_user_name_list): Rename to...
5668 (muscle_user_name_list_grow): ... this for consistency and use

5674
5675 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
5676
5677 * src/print.c (lookahead_set, state_default_rule): Remove.
5678 (print_reductions): Replace state_default_rule invocation with
5679 equivalent use of yydefact, which was computed in token_actions in
5680 tables.c.
5681 (print_results): Don't allocate lookahead_set.
5682
5683 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
5684
5685 * data/lalr1.java: Prefix all private members with yy.
5686
5687 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
5688
5689 Use YYFPRINTF instead of fprintf where appropriate. Reported by
5690 Sebastien Fricker at
5691 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
5692 * THANKS: Add Sebastien Fricker.
5693 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
5694 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
5695 accept a variable number of arguments.
5696
5697 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
5698
5699 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
5700
5701 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>

5704 * djgpp/config.sed: Adjustments concerning the use of autoconf 2.61.
5705 * djgpp/config.site: Adjustments concerning the use of autoconf 2.61.
5706
5707 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
5708
5709 Undo my 2007-02-07 change, switching back to the c-strcase module
5710 introduced in the 2007-02-03 change. Bruno Haible reported that
5711 the 2007-02-07 change would be dangerous in Turkish if we add a
5712 language whose name contains "i", since "i" is not lowercase "I"
5713 in Turkish.
5714 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
5715 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
5716 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
5717 * m4/.cvsignore: Remove strcase.m4.
5718 * src/getargs.c: Revert 2007-02-07 change, as follows.
5719 Include c-strcase.h.
5720 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
5721
5722 2007-02-11 Bruno Haible <bruno@clisp.org>
5723
5724 Enable the Java related testsuite tests when the only Java compiler
5725 found is a gcj < 4.3. Discussed at
5726 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
5727 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
5728
5729 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
5730
5731 * data/Makefile.am: Update copyright date.
5732 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
5733 yypstate_new returns NULL.
5734 (yypstate_new): Return NULL if malloc does.
5735 * src/reader.c (packgram): Move translation of rule actions from the
5736 beginning of packgram to...
5737 (check_and_convert_grammar): ... here right before packgram is invoked
5738 so it's easier to write more complete comments, and remove redundant
5739 code.
5740
5741 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
5742
5743 As in semantic actions, make @$ in %initial-action, %destructor, and
5744 %printer imply %locations.
5745 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
5746 scanning @$.
5747 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
5748 (@$ in %initial-action implies %locations,
5749 @$ in %destructor implies %locations,
5750 @$ in %printer implies %locations): ... these new test cases.
5751
5752 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
5753
5754 Undo most of the 2007-02-03 change, switching to the strcase module
5755 now that gnulib strcase has been fixed.
5756 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
5757 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
5758 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
5759 * m4/.cvsignore: Add strcase.m4.
5760 * src/getargs.c: Revert 2007-02-03 change, as follows.
5761 Don't include c-strcase.h.
5762 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
5763 strcasecmp has "unspecified behavior" outside the POSIX locale,
5764 but it works fine in practice if at least one argument is ASCII,
5765 as is the case in Bison.
5766
5767 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
5768
5769 * tests/java.at: Skip tests if only one of javac/java is present.
5770 Reported by Joel E. Denny.
5771 * tests/atlocal.in: Adjust copyright years.
5772
5773 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
5774
5775 * data/lalr1.java (Stack): Work around old verifiers that disallow
5776 access to the private fields of an inner class, from the outer class.
5777 We can make Stack's fields public because user code doesn't have access

5780 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
5781
5782 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
5783 the right spot for these files?

5785 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
5786 c-strncasecmp.c.
5787 * src/getargs.c: Include c-strcase.h.
5788 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
5789 to avoid unspecified behavior.

5828
5829 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
5830
5831 Clean up.
5832 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
5833 at_directive_argv arguments so these no longer have to be global
5834 variables. Also, update the implementation for the following changes.
5835 (fail_for_at_directive_too_many_args,
5836 fail_for_at_directive_too_few_args): Add at_directive_name argument.
5837 (at_directive_name): Remove as at_directive_argv[0] will be used for
5838 this now.
5839 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
5840 for the directive name.
5841 (at_directive_argc, at_directive_argv): Make these local within
5842 skel_lex instead of global.

5850 (installed skeleton file names): ... this.
5851
5852 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
5853
5854 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
5855 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
5856 Summary" not "Directives".
5857 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
5858 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
5859 since the former is now the more complete one.
5860 (Prologue Alternatives): Likewise and do the same for %defines.
5861 (Table of Symbols): Add summary of %code, add summary of %define, and
5862 move full %code documentation to...
5863 (Decl Summary): ... here for consistency with other entries in these
5864 sections.
5865 Move %define entry in order to keep this list alphabetized.
5866 Reword %define entry a little to put less emphasis on the skeleton
5867 concept, which most users shouldn't have to think about.
5868
5869 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
5870
5871 Adjust to recent gnulib changes.
5872 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
5873 Add string.h, string_.h, unistd_.h, wchar_.h.
5874 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
5875 * src/system.h: Don't include <stpcpy.h>; this is now done by
5876 <string.h>.
5877
5878 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
5879
5880 Simplify implementation of unqualified %code, implement macros for
5881 uniform treatment of boolean %define flags. Document %define.
5882 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
5883 b4_percent_code_ifdef): New.
5884 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
5885 * data/c++.m4: Define default value for global_tokens_and_yystype.
5886 * data/glr.cc: Likewise.
5887 * data/location.cc: Use b4_percent_define_flag_if.
5888
5889 * doc/bison.texinfo (Decl Summary): Document %define.
5890
5891 * src/parse-gram.y (Unqualified %code): Change muscle name to
5892 b4_percent_code().
5893 (content.opt): Default to empty.
5894
5895 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
5896
5897 Implement support for relative and absolute skeleton file names.
5898 Discussed starting at
5899 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
5900 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
5901 (Bison Options): Document in --skeleton entry.
5902 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
5903 full_skeleton can't necessarily hold all of pkgdatadir.
5904 If the specified skeleton file name contains a `/', don't prepend
5905 pkgdatadir.
5906 * src/parse-gram.y (prologue_declaration): If the specified skeleton
5907 file name contains a `/', prepend the grammar file directory.
5908 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
5909 * skeletons.at: New file.
5910 (relative skeleton file names): New test case.
5911 (installed skeleton file names): New test case.
5912 * tests/testsuite.at: Include skeletons.at.
5913
5914 * bootstrap: Update copyright to 2007.
5915
5916 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
5917
5918 * bootstrap: Remove occurrences of .#bootmp from the files.
5919
5920 2007-01-17 Akim Demaille <akim@epita.fr>
5921
5922 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
5923 nonterminals.
5924 Use per-type %printer.
5925
5926 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
5927
5928 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,

5935
5936 2007-01-16 Akim Demaille <akim@epita.fr>
5937
5938 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
5939 error code.
5940 (Calc++ Scanner): Exit with failure if we can't open the input
5941 file.
5942 Accept "-" standing for stdin.
5943 (Calc++ Top Level): Print the result only if the parsing was
5944 successful.
5945
5946 2007-01-16 Akim Demaille <akim@epita.fr>
5947
5948 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
5949
5950 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
5951 and Joel E. Denny <jdenny@ces.clemson.edu>
5952
5953 Clean up %define and %code implementation in M4 some. Most
5954 importantly, rename all related macros to be in the b4_percent_define
5955 and b4_percent_code namespaces. Also, complete support for `.' in
5956 %define variable names and %code qualifiers.
5957 * data/bison.m4 (b4_check_user_names): Check for special
5958 "SKELETON-NAMESPACE(name)" macros instead of using two nested
5959 m4_foreach loops.
5960 (b4_get_percent_define, b4_get_percent_code): Rename to...
5961 (b4_percent_define_get, b4_percent_code_get): ... these.
5962 Extend documentation with examples.
5963 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
5964 b4_percent_define_skeleton_variables and
5965 b4_percent_code_skeleton_qualifiers.
5966 Expect any value for the %define variable `foo' to be stored in the
5967 macro named `b4_percent_define(foo)'; expect any %code blocks for the
5968 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
5969 expect any unqualified %code blocks to be stored in a macro named
5970 `b4_percent_code_unqualified'.
5971 Use m4_indir so that %define variable names and %code qualifiers can
5972 contain `.', which is allowed by the grammar parser.
5973 (b4_percent_define_default): New macro to set a default value for a
5974 %define variable.
5975 (m4_wrap): Update wrapped code, and fix some underquoting.
5976 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
5977 Expect grammar uses of %define variables and %code qualifiers to be
5978 defined in b4_percent_define_user_variables and
5979 b4_percent_code_user_qualifiers.
5980 * data/c++.m4: Use b4_percent_define_default rather than
5981 m4_define_default. Fix some underquoting. Skeleton usage of %define
5982 variable define_location_comparison now implies skeleton usage of
5983 %define variable filename_type.
5984 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
5985 data/push.c, data/yacc.c: Update macro names.
5986 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
5987 muscle names.
5988
5989 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
5990
5991 DJGPP specific issues.
5992
5993 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
5994 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
5995
5996 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
5997
5998 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
5999 run parsers in all tests so that Valgrind is invoked during
6000 maintainer-check-valgrind.
6001 (Duplicate representation of merged trees): Free all semantic values.
6002 (Duplicated user destructor for lookahead): Likewise.
6003
6004 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
6005
6006 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
6007 command-line prefix.
6008 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
6009 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
6010 miss Valgrind messages.
6011 (Exploding the Stack Size with Malloc): Likewise.
6012
6013 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
6014
6015 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
6016 locals. Reported by Juan Manuel Guerrero at
6017 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
6018 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
6019 Fix some indentation also.
6020 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
6021 explaining this issue.
6022
6023 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
6024 and Joel E. Denny <jdenny@ces.clemson.edu>
6025
6026 Simplify union and prologue handling, and escape union and lex/parse
6027 params with digraphs.
6028 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
6029 values to the empty string since these are no longer guaranteed
6030 initialized by the front-end.
6031 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
6032 braces around b4_user_stype since this is no longer done by the
6033 front-end.
6034 * src/files.c, src/files.h (pre_prologue_obstack,
6035 post_prologue_obstack): Remove.
6036 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
6037 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
6038 with digraphs. This fixes lex params and parse params.
6039 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
6040 * src/output.c (prepare): Remove muscle insertion of the prologues.
6041 (output): Remove freeing of pre_prologue_obstack and
6042 post_prologue_obstack.
6043 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
6044 than prologue_augment for prologue parsing so you don't need prologue
6045 obstacks.
6046 (grammar_declaration): For %union RHS, use `braceless' instead of
6047 "{...}" so that braces are already stripped and code is escaped with
6048 digraphs.
6049 * src/reader.c (prologue_augment): Remove.
6050 (reader): Remove initialization of pre_prologue_obstack and
6051 post_prologue_obstack.
6052 * src/reader.h (prologue_augment): Remove.
6053
6054 * data/c.m4: Remove stray parenthesis.
6055
6056 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6057
6058 Remove quotes from variables names in %define directives and from
6059 qualifiers in %code directives, and restrict the characters that are
6060 allowed in them to M4-friendly ones. For %define, continue to support
6061 the quoted form as a deprecated feature. Discussed starting at
6062 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
6063 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
6064 %code.
6065 * doc/bison.texinfo (Prologue Alternatives): Update.
6066 (Decl Summary): In %defines entry, update mention of `%code requires'
6067 and `%code provides'.
6068 (C++ Location Values): Update %define uses.
6069 (Calc++ Parser Interface): Likewise.
6070 (Calc++ Parser): Likewise, and update `%code requires' uses.
6071 (Table of Symbols): Update %code documentation.
6072 * src/parse-gram.y (prologue_declaration): For %define variables, use
6073 `variable' instead of `STRING'.
6074 (grammar_declaration): For %code qualifiers, use `ID' instead of
6075 `STRING'.
6076 (variable): New nonterminal that takes an `ID' or a `STRING'.
6077 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
6078 and %define uses.
6079 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
6080 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
6081 (%define errors): Update %define uses.
6082
6083 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6084
6085 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
6086 instead of muscle_insert for %define values so that M4-special
6087 characters are replaced with digraphs.
6088 * tests/input.at (%define errors): Extend to check weird values.
6089
6090 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6091
6092 Instead of having skeletons declare all valid %define variables and
6093 %code qualifiers, provide macros that retrieve the associated values
6094 and build these lists automatically. Thus Bison will now warn when a
6095 variable or qualifier is not used by the skeleton in the current
6096 invocation regardless of whether it might sometimes be used by that
6097 skeleton in other invocations. Also, move all %define value macros to
6098 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
6099 form, which is replaced by %code.
6100 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
6101 (b4_check_user_names): ... this, and change the series of valid name
6102 arguments to a single list argument for names used in the skeleton
6103 similar to the existing list argument for names used in the grammar.
6104 Warn instead of complaining.
6105 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
6106 values and %code code, to format %code code properly, and to build
6107 lists of all %define variables and %code qualifiers used in the
6108 skeleton: b4_skeleton_percent_define_variables and
6109 b4_skeleton_percent_code_qualifiers.
6110 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
6111 Remove, and...
6112 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
6113 the skeleton names lists can finish building first. In place of
6114 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
6115 expect the lists b4_user_percent_define_variables and
6116 b4_user_percent_code_qualifiers.
6117 * data/c++.m4: Where setting default values for b4_parser_class_name,
6118 b4_location_type, b4_filename_type, b4_namespace, and
6119 b4_define_location_comparison, update their names to the
6120 b4_percent_define_ namespace.
6121 * data/glr.c: Don't use b4_check_percent_define_variables and
6122 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
6123 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
6124 (b4_parser_class_name, b4_namespace): Define these using
6125 b4_get_percent_define for parser_class_name and namespace.
6126 * data/location.cc: Use b4_get_percent_define.
6127 * data/push.c: Don't use b4_check_percent_define_variables and
6128 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
6129 * data/yacc.c: Likewise, and don't call m4_exit in
6130 b4_use_push_for_pull_if or m4_wrap code will never execute.
6131 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
6132 Rename to...
6133 (muscle_grow_user_name_list): ... this for consistency with the
6134 terminology used in bison.m4.
6135 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
6136 %define variable names, and rename muscle used_percent_define_variables
6137 to user_percent_define_variables.
6138 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
6139 user_percent_code_qualifiers.
6140 (content): Remove.
6141 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
6142 {CODE} form is no longer accepted.
6143 * tests/input.at (Reject bad %code qualifiers): Rename to...
6144 (Reject unused %code qualifiers): ... this, and update test output.
6145 (%define error): Update test output.
6146
6147 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
6148
6149 Check for unrecognized %define variables similar to checking for
6150 unrecognized %code qualifiers. Check for redefined %define variables.
6151 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
6152 generalizes...
6153 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
6154 (b4_check_percent_define_variables): New, also wraps it.
6155 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
6156 variables using b4_check_percent_define_variables.
6157 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
6158 all those exercised in the test suite and all those listed in the
6159 `Default values' section of c++.m4. Are there others?
6160 * data/push.c, data/yacc.c: Declare no valid %define variables.
6161 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
6162 similar to muscle_find, but it works even when the muscle stores a
6163 const value.
6164 (muscle_grow_used_name_list): New function for constructing the used
6165 name list muscles that b4_check_for_unrecognized_names requires.
6166 * src/parse-gram.y (prologue_declaration): Warn if a variable is
6167 %define'd more than once. Define the b4_used_percent_define_variables
6168 muscle with muscle_grow_used_name_list.
6169 (grammar_declaration): Abbreviate %code code with
6170 muscle_grow_used_name_list.
6171 * tests/input.at (%define errors): New.
6172
6173 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6174
6175 Provide warn_at, complain_at, and fatal_at function callbacks to the
6176 skeletons, and use this for %code qualifier complaints.
6177 * data/bison.m4 (b4_error_at): New, invoked by...
6178 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
6179 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
6180 @fatal_at(...@) directives.
6181 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
6182 qualifiers in b4_used_percent_code_qualifiers and to use
6183 b4_complain_at.
6184 * src/location.c, src/location.h (boundary_set_from_string): New global
6185 function.
6186 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
6187 function.
6188 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
6189 to b4_used_percent_code_qualifiers.
6190 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
6191 function.
6192 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
6193 (lineno): Rename to...
6194 (out_lineno): ... this so I don't misunderstand it again.
6195 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
6196 here; these newlines are in the input but not the output file.
6197 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
6198 (at_directive_perform): ... this new static function, and add handling
6199 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
6200 directives.
6201 * tests/input.at (Reject bad %code qualifiers): Update test output with
6202 locations and extend.
6203
6204 * tests/output.at (Output file name: [, Output file name: ]): Remove
6205 bogus comment about these tests failing.
6206
6207 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6208
6209 Clean up b4_check_percent_code_qualifiers a little.
6210 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
6211 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
6212 documentation and add examples.
6213 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
6214 qualifiers here.
6215
6216 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6217
6218 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
6219 unreliable -- especially when they're hidden inside another macro.
6220 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
6221 data/c.m4: Remove m4_divert(-1).
6222 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
6223 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
6224 m4_divert_push(0) and m4_divert_pop(0).
6225 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
6226 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
6227 pushed and popped by m4sugar, should be first on the stack.
6228
6229 Provide warn, complain, and fatal function callbacks to the skeletons.
6230 This provides more flexibility than m4_fatal, improves the error
6231 message format, and captures messages for translation. Discussed
6232 starting at
6233 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
6234 * data/bison.m4 (b4_error): New, invoked by...
6235 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
6236 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
6237 directives. Because these M4 macros might be called when the current
6238 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
6239 the previous removal of uses of m4_divert, which caused trouble.
6240 (b4_check_percent_code_qualifiers): Use b4_complain instead of
6241 m4_fatal to report unrecognized %code qualifiers.
6242 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
6243 push parser requests.
6244 * data/glr.c: Use b4_complain instead of m4_fatal to report
6245 non-deterministic push parser requests.
6246 Update @output usage to @output(...@) form.
6247 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
6248 report missing %defines. Update @output usage to @output(...@) form.
6249 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
6250 @output(...@) form.
6251 * src/main.c (main): Invoke skel_scanner_free.
6252 * src/scan-skel.h (skel_scanner_free): Prototype new function.
6253 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
6254 obstack_for_string from flex-scanner.h.
6255 (YY_DECL): Use to declare skel_lex static.
6256 (decode_at_digraphs): Remove; now handled in the new
6257 SC_AT_DIRECTIVE_ARG start condition.
6258 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
6259 functions.
6260 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
6261 at_directive_argv): New static globals.
6262 (INITIAL): Use fail_for_invalid_at.
6263 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
6264 recognize the start of a generalized `@directive(...@)' form and
6265 start...
6266 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
6267 directive args (using the new obstack_for_string), to decode the
6268 contained @ diagraphs, and to perform the directive. It recognizes
6269 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
6270 @output(...@).
6271 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
6272 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
6273 `@,'.
6274 (scan_skel): Initialize obstack_for_string on the first call.
6275 (skel_scanner_free): New function to free obstack_for_string.
6276 * tests/input.at (Reject bad %code qualifiers): Update test output.
6277
6278 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
6279
6280 Consolidate the 4 prologue alternative directives (%code, %requires,
6281 %provides, and %code-top) into a single %code directive with an
6282 optional qualifier field. Discussed at
6283 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
6284 * NEWS (2.3a+): Rewrite the existing entry for the prologue
6285 alternatives.
6286 * doc/bison.texinfo (Prologue Alternatives): Update.
6287 (Decl Summary): Update to %code "requires" and %code "provides".
6288 (Calc++ Parser): Update to %code "requires".
6289 (Table of Symbols): Remove entries for %requires, %provides, and
6290 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
6291 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
6292 are replaced by b4_percent_code_provides and b4_percent_code_requires,
6293 which are skeleton-specific.
6294 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
6295 declare what %code qualifiers it supports and to complain if any other
6296 qualifiers were used in the grammar.
6297 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
6298 and b4_user_code([b4_percent_code_provides]) in place of
6299 b4_user_requires and b4_user_provides.
6300 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
6301 Add b4_user_code([b4_percent_code_top]) and
6302 b4_user_code([b4_percent_code]).
6303 Invoke b4_check_percent_code_qualifiers.
6304 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
6305 PERCENT_REQUIRES): Remove.
6306 (grammar_declaration): Remove RHS's for %code-top, %provides, and
6307 %requires. Rewrite the %code RHS as the unqualified form defining the
6308 muscle b4_percent_code. Add another RHS for the qualified %code form,
6309 which defines muscles of the form b4_percent_code_QUALIFIER and the
6310 b4_used_percent_code_qualifiers muscle.
6311 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
6312 PERCENT_REQUIRES): Remove.
6313 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
6314 %code "requires" and %code "provides".
6315 * tests/input.at (Reject bad %code qualifiers): New.
6316
6317 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
6318
6319 Use the new code_props interface for destructors and printers.
6320 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
6321 printer_location members, and change the type of the destructor and
6322 printer members to code_props.
6323 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
6324 symbol_printer_get, semantic_type_destructor_set,
6325 semantic_type_printer_set, default_tagged_destructor_set,
6326 default_tagless_destructor_set, default_tagged_printer_set,
6327 default_tagless_printer_set): Use code_props in arguments and return
6328 types in place of char const * and location.
6329 (symbol_destructor_location_get, symbol_printer_location_get): Remove
6330 since the locations are now contained in the return of
6331 symbol_destructor_get and symbol_printer_get.
6332 * src/output.c (symbol_destructors_output, symbol_printers_output):
6333 Replace with...
6334 (symbol_code_props_output): ... this to eliminate duplicate code.
6335 (output_skeleton): Update to use symbol_code_props_output.
6336 * src/reader.c (symbol_should_be_used): Update use of
6337 symbol_destructor_get.
6338 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
6339 Update uses of the various _destructor_set and _printer_set functions.
6340 * src/symtab.c: (default_tagged_destructor_location,
6341 default_tagless_destructor_location, default_tagged_printer_location,
6342 default_tagless_printer_location): Remove since we...
6343 (default_tagged_destructor, default_tagless_destructor,
6344 default_tagged_printer, default_tagless_printer): ... change the type
6345 of these to code_props.
6346 (symbol_new, semantic_type_new, symbol_destructor_set,
6347 semantic_type_destructor_set, symbol_destructor_get,
6348 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
6349 symbol_check_alias_consistency, default_tagged_destructor_set,
6350 default_tagless_destructor_set, default_tagged_printer_set,
6351 default_tagless_printer_set): Update.
6352 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
6353 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
6354 code_props members.
6355 (symbol_print): Use SYMBOL_CODE_PRINT.
6356
6357 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
6358
6359 Use the new code_props interface for rule actions.
6360 * src/symlist.h (symbol_list): Replace action, action_location, and
6361 used members with a code_props action_props member.
6362 * src/reader.c (symbol_should_be_used, grammar_rule_check,
6363 grammar_midrule_action, grammar_current_rule_merge_set,
6364 grammar_current_rule_symbol_append, packgram): Update.
6365 * src/scan-code.h (translate_rule_action): Remove, no longer used.
6366 * src/scan-code.l (handle_action_dollar): Update.
6367 (translate_rule_action): Remove, no longer used.
6368 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
6369
6370 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
6371
6372 Use the new code_props interface in parse-gram.y.
6373 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
6374 Update all uses of translate_* functions to use the new code_props
6375 interface and to use gram_scanner_last_string_free and
6376 code_scanner_last_string_free where possible.
6377 (grammar_declaration): symbol_list_destructor_set and
6378 symbol_list_printer_set now perform the translation, so don't do it
6379 here. Use gram_scanner_last_string_free where possible.
6380 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
6381 translate_code): Remove, no longer used.
6382 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
6383 symbol_list_printer_set): Perform code translation here rather than
6384 depending on the caller to do so.
6385
6386 * src/symlist.h (struct symbol_list): Correct some documentation typos.
6387 * src/scan-gram.h (gram_last_string): Remove declaration.
6388 * src/scan-gram.l (last_string): Declare it static.
6389
6390 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
6391
6392 Encapsulate code properties and related functionality for the various
6393 destructors, printers, and actions into a code_props structure and
6394 interface. This patch merely implements code_props in scan-code.h and
6395 scan-code.l. Future patches will rewrite other modules to use it.
6396 Discussed starting at
6397 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
6398 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
6399 consistently initialize const structs that have an empty location
6400 field.
6401 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
6402 to ensure consistency.
6403 * src/scan-code.h (code_props): New structure.
6404 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
6405 function, macro, and const global variable for initializing a
6406 code_props with no code.
6407 (code_props_plain_init, code_props_symbol_action_init,
6408 code_props_rule_action_init, code_props_translate_code): The rest of
6409 the new code_props functional interface. Among other things, the init
6410 functions set the code_props kind field so that
6411 code_props_translate_code will know whether to behave like
6412 translate_symbol_action, translate_rule_action, or translate_code.
6413 These old translate functions must remain until all other modules are
6414 updated to use the new code_props interface.
6415 (code_scanner_last_string_free): New function similar to
6416 gram_scanner_last_string_free.
6417 (code_scanner_free): Add documentation.
6418 * src/scan-code.l: Implement the new interface.
6419 (code_lex): Make it static, add a code_props* argument, and remove the
6420 rule argument.
6421 (last_string): New static global similar to the one in scan-gram.l.
6422 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
6423 instead of rule.
6424 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
6425 code_props since Bison may one day use this information for destructors
6426 and printers.
6427 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
6428 (handle_action_dollar): Use symbol_list_n_get and set used flag
6429 directly since symbol_list_n_used_set is removed.
6430 (translate_action): Add a code_props* argument and remove the rule,
6431 action, and location arguments. Pass the code_props* on to code_lex.
6432 (translate_rule_action, translate_symbol_action, translate_code):
6433 Rewrite as wrappers around the new code_props interface.
6434 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
6435 it would eventually need to break the encapsulation of code_props.
6436
6437 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
6438
6439 * etc/.cvsignore: New.
6440
6441 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
6442
6443 Add maintainer-push-check to run maintainer-check using push parsing in
6444 place of pull parsing where available.
6445 * Makefile.am (maintainer-push-check): New.
6446 * data/bison.m4 (b4_use_push_for_pull_if): New.
6447 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
6448 appropriately based on their existing values.
6449 (yypush_parse): Don't print push-parser-specific diagnostics if push
6450 parsing is being used in place of pull parsing.
6451 * data/yacc.c: If push parsing should replace pull parsing, redirect to
6452 push.c.
6453 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
6454 variable, and insert b4_use_push_for_pull_flag into muscles.
6455 * tests/Makefile.am (maintainer-push-check): New.
6456
6457 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
6458
6459 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
6460 (whether successful or failed) so that yypush_parse can be invoked
6461 again to start a new parse using the same yypstate.
6462 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
6463 check multiple yypull_parse invocations on the same yypstate. For pull
6464 mode, extend to check multiple yyparse invocations.
6465 (Exploding the Stack Size with Alloca): Extend to try with
6466 %push-pull-parser.
6467 (Exploding the Stack Size with Malloc): Likewise.
6468
6469 * tests/calc.at (Simple LALR Calculator): Don't specify
6470 %skeleton "push.c" since %push-pull-parser implies that now.
6471 * tests/headers.at (export YYLTYPE): Don't check for the push
6472 declarations. Otherwise, this test case can't be used to see if push
6473 mode can truly emulate pull mode.
6474 * tests/input.at (Torturing the Scanner): Likewise.
6475 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
6476 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
6477 AT_YACC_IF, which now includes the case of push mode since %skeleton
6478 need not be used for push mode. This will be more intuitive once
6479 push.c is renamed to yacc.c.
6480
6481 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
6482
6483 For push mode, convert yyparse from a macro to a function, invoke yylex
6484 instead of passing a yylexp argument to yypull_parse, and don't
6485 generate yypull_parse or yyparse unless %push-pull-parser is declared.
6486 Discussed starting at
6487 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
6488 * data/bison.m4 (b4_pull_if): New.
6489 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
6490 * data/push.c: Improve M4 quoting a little.
6491 (b4_generate_macro_args, b4_parenthesize): Remove.
6492 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
6493 any time a pull parser is requested.
6494 Don't #define this as a wrapper around yypull_parse. Instead, when
6495 both push and pull are requested, make it a function that does that
6496 same thing.
6497 (yypull_parse): If there's a b4_prefix, #define this to
6498 b4_prefix[pull_parse] when both push and pull are requested.
6499 Don't define this as a function unless both push and pull are
6500 requested.
6501 Remove the yylexp argument and hard-code yylex invocation instead.
6502 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
6503 %push-parser.
6504 * src/getargs.c (pull_parser): New global initialized to true.
6505 * getargs.h (pull_parser): extern it.
6506 * src/output.c (prepare): Insert pull_flag muscle.
6507 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
6508 (prologue_declaration): Set both push_parser and pull_parser = true for
6509 %push-pull-parser. Set push_parser = true and pull_parser = false for
6510 %push-parser.
6511 * src/scan-gram.l: Don't accept %push_parser as an alternative to
6512 %push-parser since there's no backward-compatibility concern here.
6513 Scan %push-pull-parser.
6514 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
6515 instead of %push-parser.
6516 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
6517 prototype it in the module that calls yyparse.
6518 * tests/input.at (Torturing the Scanner): Likewise.
6519 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
6520
6521 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
6522
6523 Update etc/bench.pl. Optimize push mode a little (the yyn change
6524 deserves most of the credit).
6525 * Makefile.am (SUBDIRS): Add etc subdirectory.
6526 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
6527 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
6528 yytoken, yyval, and yyloc declarations to...
6529 (yyparse or yypush_parse): ... here to improve performance. For
6530 yypush_parse invocations after the first, be sure to assign yyn its old
6531 value again.
6532 (yypstate_new): Don't bother initializing the yyresult field since the
6533 initial value isn't used.
6534 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
6535 remove the #define that, in push mode, set it to yyps->NAME.
6536 * etc/Makefile.am: New.
6537 * etc/bench.pl: Remove and build it instead from...
6538 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
6539 "tests/bison" from the build directory by default rather than just
6540 invoking "bison" from $PATH.
6541 (calc_grammar): Update push parser code: don't declare yylval globally,
6542 don't define yyparse_wrapper, and don't #define yyparse.
6543 (bench_grammar): Update to check all working combinations of yacc.c,
6544 push.c, impure, pure, pull, and push.
6545
6546 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
6547
6548 For push mode, add pull wrappers around yypush_parse.
6549 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
6550 (yypull_parse): New function wrapping yypush_parse.
6551 (yyparse): New #define wrapping yypull_parse.
6552 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
6553 is declared.
6554 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
6555 prototype yylex in the module that calls yyparse, and don't prototype
6556 yyparse there. Otherwise, the yyparse expansion won't compile.
6557 * tests/input.at (Torturing the Scanner): Likewise.
6558
6559 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
6560
6561 Enable push parsers to operate in impure mode. Thus, %push-parser no
6562 longer implies %pure-parser. The point of this change is to move
6563 towards being able to test the push parser code by running the entire
6564 test suite as if %push-parser had been declared.
6565 * data/push.c (yypush_parse): For impure mode, remove the
6566 yypushed_char, yypushed_val, and yypushed_loc arguments.
6567 Instead, declare these as local variables initialized to the global
6568 yychar, yylval, and yylloc.
6569 For the first yypush_parse invocation only, restore the initial values
6570 of these global variables when it's time to read a token since they
6571 have been overwritten.
6572 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
6573 %push-parser.
6574 * tests/calc.at (Simple LALR(1) Calculator): Always declare
6575 %pure-parser along with %push-parser since this test case was designed
6576 for pure push parsers.
6577 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
6578 (AT_YACC_OR_PUSH_IF): New.
6579 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
6580 add a note that it's still wrong for some cases (as it has been for a
6581 while).
6582 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
6583 %push-parser no longer implies %pure-parser.
6584
6585 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
6586
6587 Remove some unnecessary differences between the pull parser code and
6588 the push parser code. This patch enables yynerrs in push mode.
6589 * data/push.c: Reformat M4 a little.
6590 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
6591 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
6592 because push mode is on. Instead, if pure mode is on, move yynerrs
6593 to...
6594 (b4_declare_parser_state_variables): ... here.
6595 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
6596 to yyps->NAME so it can be used in yypush_parse.
6597 (yypush_parse): Don't omit uses of yynerrs in push mode.
6598
6599 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
6600
6601 Fix bug such that the first pushed token's value and location are
6602 sometimes overwritten (sometimes by %initial-action) before being used.
6603 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
6604 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
6605 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
6606 more closely mimic the pull parser logic.
6607 Don't copy the pushed token to yychar, yylval, and yylloc until it's
6608 time to read a token, which is after any initialization of yylval and
6609 yylloc.
6610 (gottoken): Rename label to...
6611 (yyread_pushed_token): ... for clarity and to avoid infringing on the
6612 user namespace.
6613
6614 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
6615
6616 Rearrange initialization of the parser state variables so that the
6617 skeleton doesn't have to have a copy for pull mode and another for push
6618 mode. This patch also fixes at least a bug such that yylloc was not
6619 initialized (with b4_location_initial_line and
6620 b4_location_initial_column) upon calling yypush_parse. However, that
6621 initialization now overwrites the first token's location;
6622 %initial-action assigning @$ already did the same thing, and both bugs
6623 will be fixed in a later patch.
6624 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
6625 (b4_declare_parser_state_variables): Remove initialization of yytoken,
6626 yyss, yyvs, yyls, and yystacksize.
6627 (yypstate_new): Remove initialization of some yypstate fields: yystate,
6628 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
6629 yylsp.
6630 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
6631 yyps->NAME so it can be used in yypush_parse.
6632 (yyparse or yypush_parse): For yypush_parse, don't print the
6633 "Starting parse" diagnostic for invocations after the first.
6634 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
6635 yypush_parse, only do it for the first invocation.
6636 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
6637 initialization to occur in yypush_parse but only on the first
6638 invocation.
6639
6640 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
6641
6642 * data/push.c: Add CPP guards around push parser declarations in both
6643 the header and the code file.
6644 In the code file, move the push parser declarations to the same place
6645 they appear in the header file.
6646 Clean up the M4 some, especially the inconsistent underquoting in
6647 some b4_c_function_def and b4_c_function_decl uses.
6648
6649 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
6650
6651 Encapsulate the push parser state variables into an M4 macro so the
6652 push skeleton doesn't have to list them again for pull mode's yyparse.
6653 For push mode, remove yypush_parse's local equivalents of these
6654 variables to eliminate unnecessary copying between the two sets at
6655 run-time. This patch also fixes at least a bug related to multiple
6656 %initial-action invocations in push mode.
6657 * data/push.c (b4_declare_parser_variables): Rename to...
6658 (b4_declare_scanner_communication_variables): ... this for clarity and
6659 update both uses.
6660 (b4_declare_yyparse_variables): Remove and move its contents to the one
6661 spot where it was invoked.
6662 (b4_declare_parser_state_variables): New macro containing the parser
6663 state variables required by push mode.
6664 (struct yypstate): Replace all fields but yynew with
6665 b4_declare_parser_state_variables.
6666 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
6667 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
6668 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
6669 (yyparse or yypush_parse): For yyparse in pull mode, replace local
6670 parser state variable declarations with
6671 b4_declare_parser_state_variables.
6672 Don't initialize parser state variables when calling yypush_parse since
6673 yypstate_new already does that.
6674 Invoke the user's initial action only upon the first yypush_parse
6675 invocation.
6676 Remove all code that copies between the local parser state variables
6677 and the yypstate.
6678
6679 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
6680
6681 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
6682 prevent a name collision in a future patch where these names will
6683 sometimes be #define'd.
6684 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
6685 since it no longer has the same name as the existing argument.
6686 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
6687
6688 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
6689 and Joel E. Denny <jdenny@ces.clemson.edu>
6690
6691 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
6692 that the argument is case-insensitive, and there's no `=' here.
6693 For the %skeleton entry, mention that %language is better.
6694 (Bison Options): Likewise for --language and --skeleton. Move the
6695 --skeleton entry so that the `Tuning the parser' section is sorted
6696 alphabetically on long options.
6697 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
6698 %language directive in detail here; cross-reference the %language
6699 documentation instead.
6700 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
6701 `%require "2.3b"' so that the example is always up-to-date.
6702 (Table of Symbols): Add entries for %language and %skeleton.
6703 * examples/extexi (normalize): Instead of replacing every %require
6704 argument with the current Bison version, just substitute for
6705 `@value{VERSION}'. This guarantees that we're testing what actually
6706 appears in the documentation.
6707 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
6708 rather than `@VERSION@'.
6709
6710 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6711
6712 * NEWS: Reword the %language news a bit, and put it earlier.
6713
6714 * src/getargs.c (skeleton_arg): Last arg is now location const *.
6715 Rewrite to simplify the logic.
6716 (language_argmatch): Likewise.
6717 (program_name): We now own this var.
6718 * src/getargs.h (struct bison_language): Use char[] rather than
6719 const char *.
6720
6721 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
6722 Java is supported.
6723 * src/complain.c (program_name): Remove decl; no longer needed.
6724 * src/main.c (program_name): Remove; now belongs to getargs.
6725
6726 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
6727
6728 * NEWS: Document %language.
6729
6730 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
6731
6732 * data/c-skel.m4, data/c++-skel.m4: New files.
6733 * data/glr.c: Complain on push parsers.
6734
6735 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
6736 over %skeleton.
6737 (Decl Summary): Document %language and %skeleton.
6738 (Command line): Document -L.
6739
6740 * examples/extexi: Rewrite %require directive.
6741 * examples/calc++/Makefile.am: Pass VERSION to extexi.
6742
6743 * src/files.c (compute_exts_from_gc): Look in language structure
6744 for .y extension.
6745 (compute_file_name_parts): Check whether .tab should be added.
6746 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
6747 (language, skeleton_arg, language_argmatch): New.
6748 (long_options): Add --language.
6749 (getargs): Use skeleton_arg, add -L/--language.
6750 * src/getargs.h: Include location.h.
6751 (struct bison_language, language, skeleton_arg, language_argmatch): New.
6752 * src/output.c (prepare): Pick default skeleton from struct language.
6753 Don't dispatch C skeletons here.
6754 * src/parse-gram.y (PERCENT_LANGUAGE): New.
6755 (prologue_declaration): Add "%language" rule, use skeleton_arg.
6756 * src/scan-gram.l ("%language"): New rule.
6757
6758 * tests/calc.at: Test %skeleton and %language.
6759 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
6760 (AT_GLR_IF): Look for %skeleton "glr.cc".
6761 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
6762 (AT_YACC_IF): Reject %language.
6763
6764 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
6765
6766 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
6767 since it wasn't used; only the typedef name 'semantic_type' is needed.
6768 Also, omit trailing white space.
6769
6770 * bootstrap: Sync from coreutils.
6771 (gnulib_extra_files): Add build-aux/announce.gen.
6772 (slurp): Adjust .gitignore files like .cvsignore files.
6773 * build-aux/announce-gen: Remove from CVS, since bootstrap
6774 now creates this.
6775
6776 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
6777
6778 Make %push-parser imply %pure-parser. This fixes several bugs; see
6779 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
6780 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
6781 pure_parser = true.
6782 * data/push.c: Don't bother testing b4_push_if when deciding whether
6783 to expand b4_declare_parser_variables globally.
6784 (yypush_parse): Likewise in here.
6785
6786 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
6787 (yy_reduce_print): Reformat M4 for readability.
6788
6789 2006-12-15 Bob Rossi <bob@brasko.net>
6790 and Joel Denny <jdenny@ces.clemson.edu>
6791
6792 * data/push.c (yypstate): Add typedef, and update all uses of
6793 struct yypstate to just yypstate.
6794 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
6795
6796 2006-12-14 Bob Rossi <bob@brasko.net>
6797
6798 * data/push.c (yypush_parse): Declare prototype regardless of
6799 %locations option.
6800
6801 2006-12-14 Bob Rossi <bob@brasko.net>
6802
6803 * data/push.c (yyparse): Remove the prototype and the #define when in
6804 push-parser mode.
6805
6806 2006-12-13 Bob Rossi <bob@brasko.net>
6807
6808 * data/push.c (yypstate_init): Rename to...
6809 (yypstate_new): ... this and use b4_c_function_def.
6810 (yypstate_delete): New.
6811 (yypush_parse): Change parameters yynval and yynlloc to be const.
6812 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
6813 yypstate_delete functions.
6814
6815 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
6816
6817 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
6818 strange test case titles. Reported by Bob Rossi.
6819
6820 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
6821
6822 * TODO: Add pointer to Sylvain Schmitz's work on static detection
6823 of potential ambiguities in GLR grammers.
6824
6825 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
6826
6827 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
6828 `bison ', use m4_index instead of m4_substr since chopping up a string
6829 containing M4-special characters causes problems here.
6830
6831 Fix a couple of bugs related to special characters in user-specified
6832 file names, and make it easier for skeletons to compute output file
6833 names with the same file name prefix as Bison-computed output file
6834 names.
6835 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
6836 b4_parser_file_name and b4_spec_defines_file instead of
6837 @output_parser_name@ and @output_header_name@, which are now redundant.
6838 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
6839 b4_parser_file_name, b4_spec_defines_file, and the new
6840 @basename(FILENAME@) instead of @output_parser_name@ and
6841 @output_header_name@, which inappropriately escaped the file names as
6842 C string literals.
6843 * src/files.c (all_but_ext): Remove static qualifier.
6844 (compute_output_file_names): Move `free (all_but_ext)' to...
6845 (output_file_names_free): ... here since all_but_ext is needed later.
6846 * src/files.h (all_but_ext): Extern.
6847 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
6848 exactly what MUSCLE_INSERT_STRING used to do.
6849 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
6850 characters are escaped properly.
6851 * src/output.c (prepare): Define muscle file_name_all_but_ext as
6852 all_but_ext.
6853 For pkgdatadir muscle, maintain previous functionality by using
6854 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
6855 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
6856 digraphs would never be expanded. Hopefully no one has M4-special
6857 characters in his Bison installation path.
6858 * src/scan-skel.l: Don't parse @output_header_name@ and
6859 @output_parser_name@ anymore since they're now redundant.
6860 In @output, use decode_at_digraphs.
6861 Parse a new @basename command that invokes last_component.
6862 (decode_at_digraphs): New.
6863 (BASE_QPUTS): Remove unused.
6864 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
6865 (Output file name): New tests.
6866
6867 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
6868
6869 Warn about output files that are generated by the skeletons and that
6870 conflict with other output files.
6871 * data/glr.c: Don't generate the header file here when glr.cc does.
6872 * src/files.c (file_names, file_names_count): New static globals.
6873 (compute_output_file_names): Invoke output_file_name_check for files
6874 not generated by the skeletons and remove existing checks.
6875 (output_file_name_check): New function that warns about conflicting
6876 output file names.
6877 (output_file_names_free): Free file_names.
6878 * src/files.h (output_file_name_check): Declare.
6879 * src/scan-skel.l: Invoke output_file_name_check for files generated by
6880 the skeletons.
6881 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
6882 (Conflicting output files): New tests.
6883
6884 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
6885
6886 * doc/bison.texinfo: Fix a couple of typos.
6887
6888 2006-12-08 Bob Rossi <bob@brasko.net>
6889
6890 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
6891 Rename to...
6892 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
6893 update all uses.
6894 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
6895 (yypush_parse): Rename yypvars argument to yyps and remove redundant
6896 local pv.
6897 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
6898 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
6899
6900 2006-12-07 Bob Rossi <bob@brasko.net>
6901 and Joel Denny <jdenny@ces.clemson.edu>
6902
6903 * data/push.c (yypvarsinit): Change return type from void* to struct
6904 yypvars*. No longer cast to void* on return.
6905 (struct yypvars): Remove yylen since it need not be remembered between
6906 yypushparse invocations.
6907 (yypushparse): Don't copy between yylen and pv->yylen.
6908
6909 2006-12-05 Bob Rossi <bob@brasko.net>
6910
6911 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
6912 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
6913 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
6914 (struct yypvars): Remove b4_declare_parser_variables.
6915 (yypvarsinit): Remove init code for removed variables.
6916 (global scope): Do not declare b4_declare_parser_variables if
6917 push or pure mode.
6918 (yypushparse): Add b4_declare_parser_variables.
6919 Init new local variables, and remove init code for removed
6920 yypvars variables.
6921 (yyparse): Delete.
6922 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
6923 and yyparse for other modes.
6924 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
6925 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
6926 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
6927 (AT_PURE_LEX_IF): True if pure or push parser.
6928
6929 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
6930
6931 Document Yacc prologue alternatives and default %destructor's and

6933 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
6934 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
6935 (2.3a): Annotate this entry to say the old forms of these features were
6936 also experimental.
6937 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
6938 Table of Symbols): Say they're experimental. Comment out any mention

6942
6943 Support a file name argument to %defines. Deprecate `=' in
6944 %file-prefix, %name-prefix, and %output. Discussed at
6945 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
6946 * NEWS (2.3a+): Mention.
6947 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
6948 form of %defines, and remove `=' from entries for %file-prefix,
6949 %name-prefix, and %output.
6950 * src/parse-gram.y (prologue_declaration): Implement.
6951 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
6952 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
6953 all but one occurrence of %name-prefix.
6954 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
6955 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
6956 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
6957 occurrence of each of %file-prefix and %output. Add check for %defines
6958 with argument.
6959 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
6960 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
6961 Remove the `=' from %output.
6962
6963 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
6964
6965 Don't escape $ in test case titles since Autoconf 2.61 now does that
6966 correctly.
6967 * tests/actions.at (Default %printer and %destructor are not for error
6968 or $undefined): Here.
6969 (Default %printer and %destructor are not for $accept): Here.
6970 * tests/input.at (Invalid $n and @n): Here.
6971
6972 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
6973
6974 Rename <!> to <>. Discussed starting at
6975 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
6976 * NEWS (2.3a+): Update.
6977 * doc/bison.texinfo (Freeing Discarded Symbols, Table of Symbols):
6978 Update.
6979 * src/parse-gram.y (TYPE_TAG_NONE, generic_symlist_item): Implement.
6980 * src/scan-gram.l (INITIAL): Implement.
6981 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
6982 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
6983 comment.
6984 * tests/actions.at (Default tagless %printer and %destructor,
6985 Default tagged and per-type %printer and %destructor,
6986 Default %printer and %destructor are not for error or $undefined,
6987 Default %printer and %destructor are not for $accept,
6988 Default %printer and %destructor for mid-rule values): Update.
6989 * tests/input.at (Default %printer and %destructor redeclared,
6990 Unused values with default %destructor): Update.
6991
6992 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
6993
6994 Don't let %prec take a nonterminal.
6995 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
6996 token.
6997 * tests/input.at (%prec takes a token): New test checking that %prec
6998 won't take a nonterminal.
6999
7000 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
7001
7002 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
7003 it was double-quoted.
7004 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
7005 grammar is maintained with Bison's highest standards.
7006 * src/getargs.c: Fix some typos in Doxygen comments.
7007
7008 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
7009
7010 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
7011 later. Reported by Paul Eggert in
7012 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
7013 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
7014 * src/scan-code.l (translate_action): Don't bother invoking
7015 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
7016 (code_scanner_free): Instead of invoking
7017 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
7018 which frees more.
7019 * src/scan-gram.l (gram_scanner_free): Likewise.
7020 * src/scan-skel.l (scan_skel): Likewise.
7021
7022 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
7023
7024 * src/files.c (tr): Change return type to void.
7025 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
7026 has been called previously for the same key.
7027 (muscle_find): Return storage instead of value so that
7028 --enable-gcc-warnings doesn't produce warnings that the return discards
7029 const. aver that the value and storage are the same since storage
7030 could potentially be NULL when value is not.
7031 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
7032 same as 0.
7033
7034 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7035
7036 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
7037 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
7038 us a slightly cleaner distribution, and also works.
7039 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
7040 gnulib changes.
7041
7042 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
7043 and Paul Eggert <eggert@cs.ucla.edu>
7044
7045 Don't let Bison leak memory except when it complains.
7046 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
7047 (spec_defines_file, dir_prefix): Now char *, not const char *,
7048 since they are freed.
7049 * src/files.c: Likewise.
7050 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
7051 Likewise.
7052 (tr): Now operates in-place. All uses changed.
7053 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
7054 values.
7055 (compute_file_name_parts, compute_output_file_names): Don't store
7056 read-only data in variables that will be freed.
7057 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
7058 src_extension, and header_extension.
7059 (output_file_names_free): New public function to free
7060 spec_verbose_file, spec_graph_file, spec_defines_file,
7061 parser_file_name, and dir_prefix.
7062 * src/getargs.c (getargs): Don't store read-only data in variables that
7063 will be freed.
7064 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
7065 (which previously existed but was unused), and quotearg_free.
7066 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
7067 * src/muscle_tab.c: Likewise.
7068 (muscle_entry): Make the value char const *,
7069 and add a new storage member that is char * and can be freed.
7070 (muscle_entry_free): New private function.
7071 (muscle_init): Use it instead of free.
7072 (muscle_insert, muscle_grow): Update and use new storage member.
7073 (muscle_code_grow): Free the string passed to muscle_grow
7074 since it's not needed anymore.
7075 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
7076 add a new `char *code' member.
7077 ("{...}"): Declare semantic type as code.
7078 * src/scan-code.h (translate_rule_action):
7079 (translate_symbol_action, translate_code, translate_action): Return
7080 `char const *' rather than `char *' since external code should not free
7081 these strings.
7082 * src/scan-code.l: Likewise.
7083 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
7084 which is "{...}" in the parser.
7085 * tests/Makefile.am (maintainer-check-valgrind): Set
7086 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
7087 Valgrind.
7088 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
7089 complain.
7090 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
7091 expecting a non-zero exit status sets --leak-check=summary and
7092 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
7093 this case, and we don't want to hear about it.
7094
7095 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
7096
7097 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
7098 instead of from the template, to simplify configuration a bit.
7099 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
7100 and m4/wint_t.m4, as they are needed with the latest gnulib.
7101
7102 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
7103
7104 Disable unset/unused mid-rule value warnings by default, and recognize
7105 --warnings=midrule-values to enable them. Discussed starting at
7106 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
7107 * NEWS (2.3a+): Mention.
7108 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
7109 warnings): Add entry for midrule-values subargument.
7110 * src/reader.c (symbol_should_be_used): Don't return true just because
7111 the value is a set/used mid-rule value unless
7112 --warnings=midrule-values was specified.
7113 * tests/input.at (Unused values, Unused values before symbol
7114 declarations): Run tests with and without --warnings=midrule-values.
7115
7116 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
7117 than LIST_FREE directly.
7118
7119 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
7120
7121 Finish implementing --warnings=error, which should not be implied by
7122 --warnings=all (or by its synonyms -W and --warnings without
7123 subarguments).
7124 * src/complain.c (set_warning_issued): New function to report that
7125 warnings are being treated as errors and to record an error if so.
7126 Invoke...
7127 (warn_at, warn): ... here.
7128 * src/getargs.c (warnings_args, warnings_types): Reorder so that
7129 "error - warnings are errors" does not appear above "all - all of the
7130 above".
7131 (getargs): For -W and --warnings without subarguments, don't let
7132 FLAGS_ARGMATCH set warnings_error in warnings_flag.
7133 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
7134
7135 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
7136
7137 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
7138 empty subargument list. For example: `bison --warnings= parser.y'.
7139
7140 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
7141
7142 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
7143 the parser header file so that gcc doesn't warn.
7144
7145 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
7146
7147 Split the default %destructor/%printer into two kinds: <*> and <!>.
7148 Discussed starting at
7149 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
7150 * NEWS (2.3a+): Mention.
7151 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
7152 previous change today related to mid-rules.
7153 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
7154 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
7155 (TYPE_TAG_ANY): Add as <*>.
7156 (TYPE_TAG_NONE): Add as <!>.
7157 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
7158 for <*> and <!>.
7159 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
7160 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
7161 * src/symlist.c (symbol_list_default_new): Split into tagged and
7162 tagless versions.
7163 (symbol_list_destructor_set, symbol_list_printer_set): Split
7164 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
7165 SYMLIST_DEFAULT_TAGLESS.
7166 * src/symlist.h: Update symbol_list_default*_new prototypes.
7167 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
7168 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
7169 * src/symtab.c (default_destructor, default_destructor_location,
7170 default_printer, default_printer_location): Split each into tagged and
7171 tagless versions.
7172 (symbol_destructor_get, symbol_destructor_location_get,
7173 symbol_printer_get, symbol_printer_location_get): Implement tagged
7174 default and tagless default cases.
7175 (default_destructor_set, default_printer_set): Split each into tagged
7176 and tagless versions.
7177 * src/symtab.h: Update prototypes.
7178 * tests/actions.at (Default %printer and %destructor): Rename to...
7179 (Default tagless %printer and %destructor): ... this, and extend.
7180 (Per-type %printer and %destructor): Rename to...
7181 (Default tagged and per-type %printer and %destructor): ... this, and
7182 extend.
7183 (Default %printer and %destructor for user-defined end token): Extend.
7184 (Default %printer and %destructor are not for error or $undefined):
7185 Update.
7186 (Default %printer and %destructor are not for $accept): Update.
7187 (Default %printer and %destructor for mid-rule values): Extend.
7188 * tests/input.at (Default %printer and %destructor redeclared): Extend.
7189 (Unused values with default %destructor): Extend.
7190
7191 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
7192
7193 Don't apply the default %destructor/%printer to an unreferenced midrule
7194 value. Mentioned at
7195 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
7196 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
7197 like $@n instead of just @n so that the default %destructor/%printer
7198 logic doesn't see them as user-defined symbols.
7199 (symbol_is_dummy): Check for both forms of the name.
7200 * src/reader.c (packgram): Remove the `$' from each midrule symbol
7201 name for which the midrule value is referenced in any action.
7202 * tests/actions.at (Default %printer and %destructor for mid-rule
7203 values): New test.
7204 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
7205 for change to dummy symbol names.
7206
7207 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
7208
7209 Warn about unset midrule $$ if the corresponding $n is used.
7210 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
7211 $n usage.
7212 (packgram): Before invoking grammar_rule_check on any rule, make sure
7213 all actions have already been scanned in order to set `used' flags.
7214 Otherwise, checking that a midrule's $$ is set will not always work
7215 properly because the midrule check must forward-reference the midrule's
7216 parent rule.
7217 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
7218 warning.
7219
7220 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
7221
7222 More improvements to the documentation of the prologue alternatives:
7223 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
7224 Bison manual.
7225 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
7226 some text to clarify the relative importance of the new directives and
7227 to show how these directives may be viewed as code labels.
7228
7229 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
7230
7231 Similar to the recently removed %before-header, add %code-top as the
7232 alternative to the pre-prologue. Mentioned at
7233 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
7234 Also, let the prologue alternatives appear in the grammar section.
7235 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
7236 (prologue_declaration): Move the existing prologue alternatives to...
7237 (grammar_declaration): ... here and add %code-top.
7238 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
7239
7240 Clean up and extend documentation for the prologue alternatives.
7241 * NEWS (2.3a+): Describe prologue alternatives.
7242 * doc/bison.texinfo (Prologue): Move discussion of prologue
7243 alternatives to...
7244 (Prologue Alternatives): ... this new section, and extend it to discuss
7245 all 4 directives in detail.
7246 (Table of Symbols): Clean up discussion of prologue alternatives and
7247 add %code-top.
7248
7249 2006-10-16 Juan Manuel Guerrero <juan.guerrero@gmx.de>
7250
7251 DJGPP specific issues.

7254 config.bat accordingly.
7255 * djgpp/config.sed: Adjust config.sed for the use of autoconf 2.60.
7256 * djgpp/config.site: Likewise.
7257
7258 2006-10-16 Paolo Bonzini <bonzini@gnu.org>
7259

7261 http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00002.html
7262
7263 * data/bison.m4 (b4_user_requires, b4_user_provides): New.
7264 (b4_user_start_header): Remove.
7265 * data/glr.c: Use new macros instead of b4_*start_header
7266 and b4_*end_header.
7267 * data/glr.cc: Likewise.
7268 * data/lalr1.cc: Likewise.
7269 * data/push.c: Likewise.

7282 Problem reported by Joel E. Denny.
7283
7284 2006-10-14 Jim Meyering <jim@meyering.net>
7285
7286 (Sync from coreutils.)
7287 Work also when the working directory (with e.g. coreutils sources)
7288 is version controlled with git, rather than CVS.
7289 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
7290 rather than CVS.
7291 In messages and comments, say e.g., "checked-out sources",
7292 rather than "CVS sources".
7293 (version_controlled_file): New function. Work for git as well as
7294 for CVS. Don't use grep's -q option.
7295 (slurp): Call it here, in place of CVS-specific code.
7296
7297 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
7298
7299 Fix testsuite for ./configure --enable-gcc-warnings:
7300 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
7301 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
7302 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
7303 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
7304 * test/regression.at (Diagnostic that expects two alternatives):
7305 Likewise.
7306
7307 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
7308
7309 * bootstrap.conf (gnulib_modules): Add config-h.
7310 * djgpp/subpipe.c: Include <config.h> unconditionally; don't
7311 worry about HAVE_CONFIG_H.
7312 * lib/abitset.c: Likewise.
7313 * lib/bitset.c: Likewise.
7314 * lib/bitset_stats.c: Likewise.
7315 * lib/bitsetv-print.c: Likewise.
7316 * lib/bitsetv.c: Likewise.

7320 * lib/subpipe.c: Likewise.
7321 * lib/timevar.c: Likewise.
7322 * lib/vbitset.c: Likewise.
7323 * lib/bitset.c: Include "bitset.h" first, to test interface.
7324 * lib/bitset_stats.c: Include "bitset_stats.h" first.
7325 * lib/bitsetv-print.c: Include "bitsetv-print.h" first.
7326 * lib/bitsetv.c: Include "bitsetv.h" first.
7327 * lib/get-errno.c: Include "get-errno.h" first.
7328 * m4/.cvsignore: Add config-h.m4.
7329 * tests/actions.at (Default %printer and %destructor for ...):
7330 Adjust expected line numbers in output to reflect removal of #if
7331 HAVE_CONFIG_H lines.
7332 * tests/glr-regression.at (Missed %merge type warnings when ...):
7333 Likewise.
7334 * tests/regression.at (Braced code in declaration in rules section):
7335 Likewise.
7336 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
7337 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
7338 Include <config.h> unconditionally.
7339
7340 * bootstrap: Sync from coreutils, as follows:
7341
7342 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
7343
7344 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
7345 variable was sometimes used without being initialized. This
7346 messed up the installation of the INSTALL file in some cases.
7347
7348 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
7349
7350 * bootstrap (usage, main program, symlink_to_gnulib): Add option
7351 --copy. Inspired by a suggestion from Bruno Haible.
7352
7353 2006-10-03 Jim Meyering <jim@meyering.net>
7354
7355 * bootstrap: Undo last change to this file, since now gnulib-tool
7356 sticks with the automake default in generating dependencies.
7357
7358 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
7359
7360 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
7361 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
7362
7363 * doc/bison.1: Add copyright notice.
7364
7365 * data/glr.c: Don't include <stdarg.h>; not used.
7366
7367 * NEWS: The -g and --graph options now output graphs in Graphviz
7368 DOT format, not VCG format.
7369 * doc/bison.1: Likewise.
7370 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
7371 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
7372 of this change in
7373 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
7374 * TODO: Remove Graphviz entry.
7375 * src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
7376 remove vcg.c, vcg.h, vcg_defaults.h.
7377 * src/vcg.c, src/vcg.h, src/vcg_defaults.h: Remove.
7378 * src/graphviz.c, src/graphviz.h: New files.

7388 Output graphviz format rather than VCG format.
7389 * tests/.cvsignore: Remove *.vcg; add *.dot.
7390 * tests/output.at: Expect *.dot files, not *.vcg files.
7391

7394
7395 2006-10-11 Bob Rossi <bob@brasko.net>
7396

7402
7403 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
7404
7405 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
7406 in a push parser. Reindent slightly to match yacc.c better.
7407
7408 2006-10-11 Bob Rossi <bob@brasko.net>
7409
7410 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
7411 yymsg_alloc fields.
7412 (yypvarsinit, yypushparse): Remove init of removed fields.
7413 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
7414
7415 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
7416
7417 * THANKS: Add Paolo Bonzini and Bob Rossi.
7418
7419 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
7420
7421 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
7422 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
7423 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
7424 b4_define_user_cde and uses): Remove.
7425 (b4_comment, b4_prefix, b4_sync_start): New.
7426 * data/bison.m4: New file, with most of the content removed from c.m4.
7427 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
7428 * src/output.c (output_skeleton): Pass bison.m4.
7429 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
7430 only if specified.
7431
7432 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
7433
7434 Fix test failure reported by Tom Lane in
7435 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
7436 and try to make such failures easier to catch in the future.
7437 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
7438 that's now the caller's responsibility.
7439 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
7440 Set yychar = YYEOF if it's negative.
7441 * tests/actions.at (yylex): Abort if asked to read past EOF.
7442 * tests/conflicts.at (yylex): Likewise.
7443 * tests/cxx-type.at (yylex): Likewise.
7444 * tests/glr-regression.at (yylex): Likewise.
7445 * tests/input.at (yylex): Likewise.
7446 * tests/regression.at (yylex): Likewise.
7447 * tests/torture.at (yylex): Likewise.
7448
7449 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
7450
7451 Fix problems with translating English-language diagnostics.
7452 * bootstrap: Fix bug introduced in recent bootstrap changes, with
7453 respect to bison-runtime pot generation. The YY_ stuff
7454 wasn't being captured.
7455 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
7456 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
7457 * runtime-po/POTFILES.in: Add data/push.c.
7458
7459 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
7460
7461 Merge bootstrap changes from coreutils.
7462
7463 2006-09-28 Jim Meyering <jim@meyering.net>
7464
7465 Automatically generated dependencies are important even
7466 when all of the sources in a directory come from gnulib.
7467 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
7468 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
7469
7470 2006-09-23 Jim Meyering <jim@meyering.net>
7471
7472 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
7473
7474 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
7475
7476 * bootstrap: Add support for --force.
7477 (usage): New function. Describe usage less tersely.
7478 (CVS_only_file): New var.
7479
7480 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
7481
7482 * data/push.c (YYPUSH_MORE): Make it an enum instead.
7483 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
7484 Adjust white space and comments to match GNU style better.
7485
7486 2006-09-20 Bob Rossi <bob@brasko.net>
7487
7488 * data/push.c (yyresult_get): Remove function.
7489 (YYPUSH_MORE): Add #define.
7490 (yypushparse): Modify return value.
7491
7492 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
7493
7494 * stamp-h.in: Remove; no longer needed.
7495 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
7496 Remove config.h, config.hin, intl (no longer created).
7497 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
7498 stamp-h1.
7499
7500 Sync bootstrap from coreutils, as follows:
7501
7502 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
7503
7504 * bootstrap (symlink_to_gnulib): New function.
7505 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
7506 to copies-of-gnulib.
7507 (cp_mark_as_generated, slurp, gnulib_files):
7508 Avoid making a copy if it's the same as the old version.
7509 (gnulib_files): Add support for this variable (used by Bison).
7510
7511 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
7512
7513 * src/getargs.c (usage): Rework to use conventions similar to
7514 coreutils, to make translation a bit easier and the code a bit
7515 smaller. Problem reported by Tim Van Holder.
7516
7517 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
7518
7519 Use some of gnulib's new modules, taken from coreutils.
7520
7521 * bootstrap: Sync from coreutils, except add support for gnulib_files.
7522 * bootstrap.conf: New file.
7523 (gnulib_modules): Add configmake, inttypes, unistd.
7524 (XGETTEXT_OPTIONS): Add complain, complain_at,
7525 fatal, fatal_at, warn, warn_at, unexpected_end.
7526 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
7527 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
7528 (gl_EARLY): Add.
7529 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
7530 (gl_INIT): Add
7531 (GNULIB_AUTOCONF_SNIPPET): Remove.
7532 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
7533 the pickiest.
7534 * lib/.cvsignore: Add inttypes_.h.
7535 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
7536 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
7537 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
7538 no-longer-necessary initializations.
7539 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
7540 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
7541 use the unistd module.
7542 * src/system.h: Likewise.
7543 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
7544 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
7545 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
7546 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
7547 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
7548 * src/system.h: Include inttypes.h unconditionally, now that we
7549 use the inttypes module. Don't bother to include stdint.h, since
7550 inttypes.h now does that for us.
7551 (LOCALEDIR): Remove, now that we use the configmake module.
7552 * src/getargs.c: Include configmake.h.
7553 * src/main.c: Likewise.
7554 * src/output.c: Likewise.
7555 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
7556 not from $abs_top_builddir, since config.h moved.
7557
7558
7559 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
7560 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
7561
7562 * src/parse-gram.y (symbol_declaration): Don't put statements
7563 before declarations; it's not portable to C89.
7564 * src/scan-code.l (handle_action_at): Likewise.
7565
7566 * src/scan-code.l: Always initialize braces_level; the old code
7567 left it uninitialized and therefore had undefined behavior.
7568
7569 Don't attempt to redefine 'assert', since it runs afoul of
7570 systems where standard headers (mistakenly) include <assert.h>.
7571 Instead, define and use our own alternative, called 'aver'.
7572 * src/reader.c: Don't include assert.h, since we no longer
7573 use assert.
7574 * src/scan-code.l: Likewise.
7575 * src/system.h (assert): Remove, replacing with....
7576 (aver): New function, taking a bool arg. All uses changed.
7577 * src/tables.c (pack_vector): Ensure that aver arg is bool,
7578 not merely an integer.
7579
7580 2006-09-15 Bob Rossi <bob@brasko.net>
7581
7582 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
7583 * data/c.m4 (YYPUSH): New.
7584 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
7585 * src/getargs.c (push_parser): New var.
7586 * src/getargs.h (push_parser): New declaration.
7587 * src/output.c (prepare): Add macro insertion of `push_flag'.
7588 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
7589 (prologue_declaration): Parse %push-parser.
7590 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
7591 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
7592 list of removed lines from the traces observed.
7593 (AT_CHECK_CALC_LALR): Added push parser tests.
7594
7595 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
7596
7597 * NEWS: Version 2.3a.
7598 * configure.ac (AC_INIT): Likewise.
7599
7600 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
7601 "#define YYSTYPE int" that caused "make maintainer-check" to fail
7602 due to header ordering dependencies. I don't know why the #define
7603 was there.
7604
7605 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
7606 runtime cost when YYDEBUG is not defined, and so that some tests
7607 that used to fail now work. Problem and initial suggestion by
7608 Paolo Bonzini.
7609 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
7610 * data/glr.cc (b4_parser_class_name):
7611 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
7612 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
7613 (yydebug_) [YYDEBUG]: New member.
7614 (yycdebug_): Now defined only if YYDEBUG.
7615 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
7616 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
7617 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
7618 if YYYDEBUG.
7619 (debug_stream, set_debug_stream, debug_level, set_debug_level):
7620 Define only if YYDEBUG.
7621 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
7622 set_debug_level.
7623 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
7624 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
7625 AT_CHECK_CALC_GLR_CC that are working now.
7626
7627 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
7628
7629 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
7630 We don't need them in glr.cc, and glr.c defines them.
7631 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
7632 assumes that defining it to anything is the same as defining
7633 it to 1. Problem reported by Paolo Bonzini.
7634
7635 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
7636
7637 * data/c.m4 (b4_null, b4_case): Define.
7638 * src/output.c (prepare_symbols): Use b4_null.
7639 (user_actions_output): Use b4_case.
7640
7641 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
7642
7643 * data/glr.c (b4_shared_declarations): Put start-header first,
7644 before any #includes that we generate, so that feature-test
7645 macros work. Problem reported by Michael Deutschmann in
7646 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
7647 * data/lalr1.cc: Likewise.
7648 * doc/bison.texinfo (Prologue): Document that feature-test macros
7649 should be defined before any Bison declarations.
7650 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
7651 that depend on location.hh after, not before, Bison decls, since
7652 we now include location.hh after the first user prologue.
7653
7654 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
7655 Sander Brandenburg in
7656 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
7657 Also, fix minor white space and comment issues.
7658 (Prologue): Mention that it's better to define feature-test macros
7659 before Bison declarations. Problem reported by Michael Deutschmann.
7660
7661 * README-cvs: Fix typo: "&" should be "&&". Problem reported
7662 by Jim Meyering.
7663 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
7664 This adjusts to recent gnulib changes.
7665
7666 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
7667
7668 Finish implementation of per-type %destructor/%printer. Discussed
7669 starting at
7670 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
7671 and
7672 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
7673 * NEWS (2.3+): Add a description of this feature to the default
7674 %destructor/%printer description.
7675 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
7676 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
7677 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
7678 list node contains a semantic type.
7679 * src/symtab.c, src/symtab.h: Extend with a table that associates
7680 semantic types with their %destructor's and %printer's.
7681 (semantic_type_from_uniqstr, semantic_type_get,
7682 semantic_type_destructor_set, semantic_type_printer_set): New functions
7683 composing the public interface of that table.
7684 (symbol_destructor_get, symbol_destructor_location_get,
7685 symbol_printer_get, symbol_printer_location_get): If there's no
7686 per-symbol %destructor/%printer, look up the per-type before trying
7687 the default.
7688 * tests/actions.at (Per-type %printer and %destructor): New test case.
7689 * tests/input.at (Default %printer and %destructor redeclared):
7690 Extend to check that multiple occurrences of %symbol-default in a
7691 single %destructor/%printer declaration is an error.
7692 (Per-type %printer and %destructor redeclared, Unused values with
7693 per-type %destructor): New test cases.
7694
7695 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
7696
7697 Require default %destructor/%printer to be declared using
7698 %symbol-default instead of an empty symbol list, and start working on
7699 new per-type %destructor/%printer. Discussed at
7700 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
7701 * NEWS (2.3+): Add %symbol-default to example.
7702 * bison.texinfo (Freeing Discarded Symbols): Likewise.
7703 (Table of Symbols): Add entry for %symbol-default.
7704 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
7705 (generic_symlist, generic_symlist_item): New nonterminals for creating
7706 a list in which each item is a symbol, semantic type, or
7707 %symbol-default.
7708 (grammar_declaration): Use generic_symlist in %destructor and %printer
7709 declarations instead of symbols.1 or an empty list.
7710 (symbol_declaration, precedence_declaration, symbols.1): Update actions
7711 for changes to symbol_list.
7712 * src/reader.c: Update for changes to symbol_list.
7713 * src/scan-code.l: Likewise.
7714 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
7715 * src/symlist.c, src/symlist.h: Extend such that a list node may
7716 represent a semantic type or a %symbol-default in addition to just an
7717 ordinary symbol. Add switched functions for setting %destructor's and
7718 %printer's.
7719 * tests/actions.at, tests/input.at: Add %symbol-default to all default
7720 %destructor/%printer declarations.
7721
7722 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
7723
7724 Whether the default %destructor/%printer applies to a particular symbol
7725 isn't a question of whether the user *declares* that symbol (in %token,
7726 for example). It's a question of whether the user by any means
7727 *defines* the symbol at all (by simply using a char token, for
7728 example). $end is defined by Bison whereas any other token with token
7729 number 0 is defined by the user. The error token is always defined by
7730 Bison regardless of whether the user declares it with %token, but we
7731 may one day let the user define error as a nonterminal instead.
7732 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
7733 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
7734 the meaning of "user-defined".
7735 * tests/actions.at (Default %printer and %destructor for user-declared
7736 end token): Rename to...
7737 (Default %printer and %destructor for user-defined end token): ...
7738 this.
7739
7740 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
7741 computation of whether to apply the default, don't maintain a list of
7742 every Bison-defined symbol. Instead, just check for a first character
7743 of '$', which a user symbol cannot have, and check for the error token.
7744
7745 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
7746
7747 Don't apply the default %destructor or %printer to the error token,
7748 $undefined, or $accept. This change fits the general rule that the
7749 default %destructor and %printer are only for user-declared symbols,
7750 and it solves several difficulties that are described in the new test
7751 cases listed below.
7752 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
7753 * tests/actions.at (Default %printer and %destructor are not for error
7754 or $undefined, Default %printer and %destructor are not for $accept):
7755 New test cases.
7756
7757 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
7758
7759 Allow %start after the first rule.
7760 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
7761 when parsing the first rule.
7762 (check_and_convert_grammar): Search for it here after all grammar
7763 declarations have been parsed. Skip midrules, which have dummy LHS
7764 nonterminals.
7765 * src/symtab.c (symbol_is_dummy): New function.
7766 * src/symtab.h (symbol_is_dummy): Declare it.
7767 * tests/input.at (%start after first rule): New test.
7768
7769 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
7770
7771 Redo some of the previous commit: add back the ability to use
7772 non-aliased/undeclared string literals since it might be useful to
7773 those declaring %token-table.
7774 * src/reader.c (check_and_convert_grammar): Undo changes in previous
7775 commit: don't worry about complaints from symbols_pack.
7776 * src/symtab.c (symbol_new, symbol_class_set,
7777 symbol_check_alias_consistency): Undo changes in previous commit: count
7778 each string literal as a new symbol and token, assign it a symbol
7779 number, and don't complain about non-aliased string literals.
7780 (symbols_pack): Since symbol_make_alias still does not decrement symbol
7781 and token counts but does still set aliased tokens to the same number,
7782 symbol_pack_processor now leaves empty slots in the symbols array.
7783 Remove those slots.
7784 * tests/regression.at (Undeclared string literal): Remove test case
7785 added in previous commit since non-aliased string literals are allowed
7786 again.
7787 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
7788 remove unnecessary string literal declarations.
7789 * tests/sets.at (Firsts): Likewise.
7790
7791 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
7792
7793 Don't allow an undeclared string literal, but allow a string literal to
7794 be used before its declaration.
7795 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
7796 symbols_pack complained.
7797 * src/symtab.c (symbol_new): Don't count a string literal as a new
7798 symbol.
7799 (symbol_class_set): Don't count a string literal as a new token, and
7800 don't assign it a symbol number since symbol_make_alias does that.
7801 (symbol_make_alias): It's not necessary to decrement the symbol and
7802 token counts anymore. Don't assume that an alias declaration occurs
7803 before any uses of the identifier or string, and thus don't assert that
7804 one of them has the highest symbol number so far.
7805 (symbol_check_alias_consistency): Complain if there's a string literal
7806 that wasn't declared as an alias.
7807 (symbols_pack): Bail if symbol_check_alias_consistency failed since
7808 symbol_pack asserts that every token has been assigned a symbol number
7809 although undeclared string literals have not.
7810 * tests/regression.at (String alias declared after use, Undeclared
7811 string literal): New test cases.
7812 (Characters Escapes, Web2c Actions): Declare string literals as
7813 aliases.
7814 * tests/sets.at (Firsts): Likewise.
7815
7816 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
7817
7818 In the grammar scanner, STRING_FINISH unclosed constructs and return
7819 them to the parser in order to improve error messages.
7820 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
7821 SC_BRACED_CODE, SC_PROLOGUE): Implement.
7822 * tests/input.at (Unclosed constructs): New test case.
7823 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
7824 seen.
7825
7826 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
7827 unused global.
7828
7829 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
7830
7831 Handle string aliases for character tokens correctly.
7832 * src/symtab.c (symbol_user_token_number_set): If the token has an
7833 alias, check and set its alias's user token number instead of its own,
7834 which is set to indicate the alias. Previously, every occurrence of
7835 the character token in the grammar overwrote that alias indicator with
7836 the character code.
7837 * tests/input.at (String aliases for character tokens): New test.
7838
7839 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
7840
7841 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
7842
7843 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
7844
7845 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
7846 to prevent failures when building on older platforms.
7847 Check for autopoint failure.
7848 Set XGETTEXT_OPTIONS to values that check for C format strings,
7849 so that translators are warned about them (this also helps
7850 prevent core dumps).
7851
7852 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
7853 function, since it simplifies our code a bit.
7854
7855 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
7856 rather than -W, so we don't get bogus warnings about sign comparisons.
7857 Add -Wpointer-arith, since that warning is useful (it reports code
7858 that does not conform to C89 and that some compilers reject).
7859 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
7860 since it's no longer needed.
7861
7862 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
7863
7864 Clean up scanners a bit.
7865 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
7866 definitions so gcc won't warn when obstack_for_string is unused.
7867 * src/scan-code.l: config.h and system.h are already #include'd by
7868 scan-code-c.c, so get rid of them here.
7869 * src/scan-gram.l: Likewise.
7870 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
7871 definitions rather than duplicating the rest of it.
7872 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
7873
7874 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
7875
7876 Suppress signed/unsigned comparison warnings for yycheck.
7877 * data/c.m4 (b4_safest_int_type): New macro.
7878 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
7879 a signed int type, cast it to b4_safest_int_type first.
7880 * data/yacc.c: Likewise.
7881 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
7882 also overwritten.
7883
7884 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
7885
7886 * doc/bison.texinfo: Fix some typos.
7887
7888 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
7889
7890 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
7891 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
7892
7893 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
7894 the latest gnulib does this a different way.
7895 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
7896 translation was patched, so stop omitting it.
7897
7898 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7899
7900 Enable declaration of default %printer/%destructor. Make the parser
7901 use these for all user-declared grammar symbols for which the user does
7902 not declare a specific %printer/%destructor. Thus, the parser uses it
7903 for token 0 if the user declares it but not if Bison generates it as
7904 $end. Discussed starting at
7905 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
7906 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
7907 and
7908 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
7909 * NEWS (2.3+): Mention.
7910 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
7911 declare a %destructor for a mid-rule's semantic value. It's just
7912 impossible to declare one specific to it.
7913 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
7914 code. Describe default %destructor form.
7915 * src/parse-gram.y (grammar_declaration): Parse default
7916 %printer/%destructor declarations.
7917 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
7918 and symbol_destructor_location_get rather than accessing the destructor
7919 and destructor_location members of struct symbol.
7920 (symbol_printers_output): Likewise but for %printer's.
7921 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
7922 again.
7923 * src/symtab.c (default_destructor, default_destructor_location,
7924 default_printer, default_printer_location): New static global
7925 variables to record the default %destructor and %printer.
7926 (symbol_destructor_get, symbol_destructor_location_get,
7927 symbol_printer_get, symbol_printer_location_get): New functions to
7928 compute the appropriate %destructor and %printer for a symbol.
7929 (default_destructor_set, default_printer_set): New functions to set the
7930 default %destructor and %printer.
7931 * src/symtab.h: Prototype all those new functions.
7932 * tests/actions.at (Default %printer and %destructor): New test to
7933 check that the right %printer and %destructor are called, that they're
7934 not called for $end, and that $$ and @$ work correctly.
7935 (Default %printer and %destructor for user-declared end token): New
7936 test to check that the default %printer and %destructor are called for
7937 a user-declared end token.
7938 * tests/input.at (Default %printer and %destructor redeclared, Unused
7939 values with default %destructor): New tests to check related grammar
7940 warnings and errors.
7941
7942 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
7943
7944 Clean up handling of %destructor for the end token (token 0).
7945 Discussed starting at
7946 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
7947 and
7948 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
7949
7950 Make the skeletons consistent in how they pop the end token and invoke
7951 its %destructor.
7952 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
7953 state, which has token number 0, since this would invoke the
7954 %destructor for the end token.
7955 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
7956 until after shifting the end token, or else it won't be popped.
7957 * data/yacc.c (yyparse): Likewise.
7958
7959 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
7960 it's the end token. Upon termination, destroy an unshifted lookahead
7961 even when it's the end token.
7962 * data/lalr1.cc (yy::parser::parse): Likewise.
7963 * data/yacc.c (yyparse): Likewise.
7964
7965 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
7966 value warnings for the end token when the user gives the end token a
7967 %destructor.
7968
7969 * tests/actions.at (Printers and Destructors): Test all the above.
7970
7971 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
7972
7973 Update to latest gnulib and gettext versions.
7974 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
7975 Add fopen-safer.
7976 (gnulib_files): Add m4/warning.m4. Don't worry about files
7977 overwritten by autopoint.
7978 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
7979 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
7980 rejects them.
7981 Don't use autoreconf; instead, invoke autopoint etc. by hand,
7982 so that we can remove the intl files at a better time.
7983 (intl_files_to_remove): Remove aclocal.m4, since it gets
7984 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
7985 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
7986 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
7987 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
7988 Remove datarootdir hack; no longer needed.
7989 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
7990 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
7991 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
7992 strdup.h.
7993 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
7994 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
7995
7996 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
7997
7998 * bootstrap: Adjust to today's change to gnulib-tool by invoking
7999 it with --assume-autoconf='latest-stable'.
8000
8001 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
8002
8003 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
8004 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
8005 YYSTYPE' and `{'.
8006 * src/muscle_tab.h (muscle_grow): Replace the header comments with
8007 those from muscle_tab.c since the old ones are misleading.
8008
8009 2006-07-13 Akim Demaille <akim@epita.fr>
8010
8011 Support %define "KEY" {VALUE}.
8012 * src/scan-code.h, src/scan-code.l (translate_action)
8013 (translate_rule_action, translate_symbol_action, translate_code):
8014 Return char *, not const char *.
8015 * src/parse-gram.y (declaration): Rename as...
8016 (prologue_declaration): this.
8017 (string_content): Remove this nonterminal, use STRING.
8018 (braceless, content, content.opt): New nonterminal.
8019 Use them.
8020 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
8021 as value.
8022 * src/scan-gram.l (getargs.h): Don't include it.
8023
8024 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
8025
8026 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
8027 rather than a for-loop that declares a local bool variable. This
8028 should work around a compatibility problem with a Cray x1e C++
8029 compiler reported by Hung Nguyen in
8030 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
8031 The for-loop was introduced in the 2004-11-17 change but I don't
8032 know why it was needed.
8033
8034 2006-07-12 Akim Demaille <akim@epita.fr>
8035
8036 * data/c.m4: Comment changes.
8037
8038 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
8039
8040 * src/complain.c (error_message, ERROR_MESSAGE): New.
8041 To factor...
8042 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
8043 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
8044
8045 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
8046
8047 * NEWS: Instead of %union, you can define and use your own union type
8048 YYSTYPE if your grammar contains at least one <type> tag.
8049 Your YYSTYPE need not be a macro; it can be a typedef.
8050 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
8051 (Union Decl, Decl Summary): Document this.
8052 * data/glr.c (YYSTYPE): Implement this.
8053 * data/glr.cc (YYSTYPE): Likewise.
8054 * data/lalr1.cc (YYSTYPE): Likewise.
8055 * data/yacc.c (YYSTYPE): Likewise.
8056 * src/output.c (prepare): Output tag_seen_flag.
8057 * src/parse-gram.y (declaration, grammar_declaration):
8058 Use 'union_seen' rather than 'typed' to determine whether
8059 %union has been seen, since grammars can now be typed without
8060 %union.
8061 (symbol_declaration, type.opt, symbol_def):
8062 Keep track of whether a tag has been seen.
8063 * src/reader.c (union_seen, tag_seen): New vars.
8064 (typed): remove.
8065 * src/reader.h (union_seen, tag_seen, typed): Likewise.
8066 * src/scan-code.l (untyped_var_seen): New variable.
8067 (handle_action_dollar): Adjust to above changes.
8068 (handle_action_dollar, handle_action_at):
8069 Improve overflow checking for outlandish numbers.
8070 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
8071 avoid new diagnostics generated by above changes.
8072 * tests/regression.at (YYSTYPE typedef): Add test to check
8073 for type tags without %union.
8074
8075 * src/symlist.c (symbol_list_length): Return int, not unsigned
8076 int, since callers expect int. This may need to get revisited
8077 once we have proper integer overflow checking.
8078
8079 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
8080 object is now static.
8081
8082 * src/getargs.c (flags_argmatch): Return void, not int,
8083 to pacify ./configure --enable-gcc-warnings.
8084
8085 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
8086 since last_string is already defined to FLEX_PREFIX (last_string).
8087
8088 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
8089
8090 Implement --warnings/-W.
8091 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
8092 replaced by...
8093 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
8094 Adjust callers.
8095 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
8096 (warnings_args, warnings_types): New.
8097 (getargs, short_options, long_options): Accept -W/--warnings.
8098 Sort the options by alphabetical order, upper case letter right
8099 before its lower case.
8100
8101 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
8102
8103 Change %merge result type clash warnings to errors. Discussed at
8104 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
8105 * src/reader.c (record_merge_function_type): Use complain_at.
8106 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
8107 declared later): Update test case results.
8108
8109 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
8110
8111 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
8112 to be in alphabetical order.
8113 (trace_args): Spelling fixes.
8114
8115 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
8116
8117 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
8118 so they don't collide with user-defined macros.
8119 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
8120 this was never guaranteed, and now that we're using gnulib stdint,
8121 which defines int_fast16_t to long int, the problem is exposed.
8122
8123 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
8124
8125 * data/c.m4 (b4_basename): Simplify a bit, since we don't
8126 need the full POSIX semantics (and weren't implementing them
8127 anyway).
8128
8129 Adjust to Autoconf 2.60 and today's gnulib.
8130 * bootstrap (gnulib_modules): Add stdint.
8131 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
8132 no longer copies it.
8133 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
8134 since stdint needs the former and wcwidth (which is now required
8135 by mbswidth) needs the latter.
8136 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
8137 work around a compatibility glitch between gettext 0.14.6 and
8138 Autoconf 2.60.
8139 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
8140 Do not check for uintptr_t, since new stdint module does the right
8141 thing.
8142 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
8143 Add stdint.h, stdint_.h, wcwidth.h.
8144 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
8145 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
8146 stdint.m4, wchar_t.m4, wcwidth.m4.
8147 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
8148 usual order for ../lib/*.h files.
8149 (file_name_split): Use last_component, not base_name, to adjust
8150 to gnulib changes.
8151 * src/parse-gram.h: Include <strverscmp.h> in the usual order
8152 for ../lib/*.h files.
8153 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
8154 Define unconditionally, since we now assume the stdint module.
8155 * src/scan-skel.l: Include <dirname.h>.
8156 (BASE_QPUTS): Use last_component, not base_name.
8157 * src/system.h: Include <unlocked-io.h> in the usual order
8158 for ../lib/*.h files. Include <stdint.h> unconditionally,
8159 since we now use the stdint module.
8160 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
8161 HAVE_UINTPTR_T, since we now use the stdint module.
8162 (base_name): Remove decl, since files now include <dirname.h>
8163 to get the decl.
8164
8165 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
8166
8167 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
8168 New, default to 1.
8169 * data/yacc.c, data/glr.c, data/location.cc: Use them.
8170 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
8171 default.
8172 * tests/calc.at: Adjust.
8173
8174 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
8175
8176 * data/c.m4 (b4_basename): New.
8177 (b4_syncline): Also output the location of its invocation (from
8178 the skeleton).
8179 (b4_user_action, b4_define_user_action, b4_user_actions)
8180 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
8181 (b4_user_stype): New.
8182 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
8183
8184 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
8185
8186 In the grammar file, the first column is 1 not 0 on the first line as
8187 on every other line.
8188 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
8189 * tests/input.at (Torturing the Scanner): Update output.
8190
8191 * src/scan-gram.l (scanner_cursor): Declare it static.
8192
8193 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
8194
8195 In warnings, say "previous declaration" rather than "first
8196 declaration".
8197 * src/symtab.c (redeclaration): Do that here.
8198 * src/reader.c (record_merge_function_type): In the case of a result
8199 type clash, report the previous declaration rather than the very first
8200 one in the grammar file.
8201 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
8202 declared later): Add a third declaration to check this behavior.
8203 * tests/input.at (Incompatible Aliases): Update output.
8204
8205 2006-06-27 Akim Demaille <akim@epita.fr>
8206
8207 * doc/Doxyfile.in: New.
8208 * doc/Makefile.am: Use it.
8209 * src/lalr.h, src/symtab.h: Initial doxygenation.
8210
8211 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
8212
8213 Don't miss %merge result type warnings just because the LHS types are
8214 declared after the %merge. This continues the effort of the previous
8215 patch.
8216 * src/reader.c (get_merge_function): Don't set the merger type yet.
8217 (record_merge_function_type): New function for setting the merger type
8218 and checking for clashes.
8219 (grammar_current_rule_merge_set): Set the location of the %merge for
8220 the current rule.
8221 (packgram): Invoke record_merge_function_type for each rule now that
8222 all symbol type declarations have been parsed.
8223 * src/reader.h (merger_list.type_declaration_location): New member
8224 storing the location of the first %merge from which the type for this
8225 merging function was derived.
8226 * src/symlist.h (symbol_list.merger_declaration_location): New member
8227 storing the location of a rule's %merge, if any.
8228 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
8229 declared later): New test to catch the error fixed by the above patch.
8230
8231 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
8232
8233 Get action warnings (grammar_rule_check) right even when symbol
8234 declarations appear after the rules. Discussed at
8235 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
8236 and
8237 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
8238 Don't mistake the type of $$ in a midrule to be that of its parent
8239 rule's $$.
8240 * src/reader.c (grammar_current_rule_end): Don't invoke
8241 grammar_rule_check yet since not all symbol declarations may have been
8242 parsed yet.
8243 (grammar_midrule_action): Likewise.
8244 Don't record whether the midrule's $$ has been used yet since actions
8245 haven't been translated yet.
8246 Record the midrule's parent rule and its RHS index within the parent
8247 rule.
8248 (grammar_current_rule_action_append): Don't translate the action yet
8249 since not all symbol declarations may have been parsed yet and, thus,
8250 warnings about types for $$, $n, @$, and @n can't be reported yet.
8251 (packgram): Translate the action and invoke grammar_rule_check now that
8252 all symbol declarations have been parsed.
8253 * src/scan-code.l (handle_action_dollar): Now that this is invoked
8254 after parsing the entire grammar file, the symbol list here in the case
8255 of a midrule is actually the midrule's empty RHS, so reference its
8256 parent rule's RHS where necessary.
8257 On the other hand, now that you can already know it's a midrule, you
8258 aren't forced to think $$ has the same type as its parent rule's $$.
8259 (handle_action_at): In the case of a midrule, reference the parent rule
8260 where necessary.
8261 * src/symlist.c (symbol_list_new): Initialize new midrule-related
8262 members.
8263 (symbol_list_length): Now that this is invoked after all rules have
8264 been parsed, a NULL symbol (rather than a NULL symbol list node)
8265 terminates a rule. symbol_list_print already does this correctly.
8266 * src/symlist.h (symbol_list.midrule_parent_rule,
8267 symbol_list.midrule_parent_rhs_index): New members so that midrules can
8268 remember their relationships with their parents.
8269 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
8270 fixed by the above patch.
8271 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
8272 implementing...
8273 (Unused values): ... this old test case and...
8274 (Unused values before symbol declarations): ... this new test case.
8275 This one is the same as `Unused values' except that all symbol
8276 declarations appear after the rules in order to catch the rest of the
8277 errors fixed by the above patch.
8278
8279 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
8280
8281 More cleanup.
8282 * src/reader.c (current_rule): Declare it static since it's no longer
8283 used outside this file.
8284 (grammar_current_rule_action_append): Remove redundant arguments from
8285 translate_rule_action invocation.
8286 * src/reader.h (current_rule): Remove this unused extern.
8287 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
8288 * src/scan-code.l (translate_rule_action): Likewise.
8289
8290 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
8291
8292 Clean up yesterday's patch.
8293 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
8294 to...
8295 * src/reader.c (grammar_current_rule_action_append): ... here for
8296 consistency with grammar_current_rule_symbol_append.
8297 * tests/regression.at (Braced code in declaration in rules section):
8298 Make yyerror and yylex static as usual.
8299
8300 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
8301
8302 Fix bug that mistakes braced code in a declaration in the rules section
8303 to be a rule action. Mentioned at
8304 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
8305 * src/scan-gram.l: Move midrule action detection from the start of the
8306 scanning of any braced code to...
8307 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
8308 action. For readability, use $2 and @2 rather than the equivalent
8309 global variables.
8310 * tests/regression.at (Braced code in declaration in rules section):
8311 New test to catch the error fixed by the above patch.
8312
8313 Work on code readability some.
8314 * src/scan-code.l (current_rule): Get rid of this misleading and
8315 redundant declaration: it's actually extern'ed in reader.h.
8316 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
8317 translate_action): Add a rule argument and use it instead of the global
8318 current_rule.
8319 (translate_rule_action): This already receives current_rule through an
8320 argument, so pass it on to translate_action instead of assigning
8321 current_rule to current_rule.
8322 (translate_symbol_action, translate_code): Pass rule = NULL to
8323 translate_action.
8324
8325 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
8326
8327 Rename %before-definitions to %start-header and %after-definitions to
8328 %end-header. Don't use these declarations to separate pre-prologue
8329 blocks from post-prologue blocks. Add new order-independent
8330 declarations %before-header and %after-header as alternatives to the
8331 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
8332 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
8333 * NEWS (2.3+): Update for these changes.
8334 * data/glr.c (b4_before_definitions): Update to...
8335 (b4_start_header): ... this.
8336 (b4_after_definitions): Update to...
8337 (b4_end_header): ... this.
8338 * data/glr.cc: Likewise.
8339 * data/lalr1.cc: Likewise.
8340 * data/yacc.c: Likewise.
8341 * doc/bison.texinfo (The prologue): Update names, and replace remaining
8342 prologue blocks with %*-header declarations.
8343 (Calc++ Parser): Likewise.
8344 (Decl Summary): Update names.
8345 (Table of Symbols): Update description.
8346 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
8347 (PERCENT_END_HEADER): ... this.
8348 (PERCENT_BEFORE_DEFINITIONS): Update to...
8349 (PERCENT_START_HEADER): ... this.
8350 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
8351 (declaration): Update token names and m4 macro names.
8352 When parsing %end-header and %start-header, invoke translate_code
8353 before muscle_code_grow, and no longer set global booleans to remember
8354 whether these declarations have been seen.
8355 Parse new %after-header and %before-header.
8356 * src/reader.c (before_definitions, after_definitions): Remove.
8357 (prologue_augment): Accept a new bool argument to specify whether to
8358 augment the pre-prologue or post-prologue.
8359 * src/reader.h (before_definitions, after_definitions): Remove these
8360 extern's.
8361 (prologue_augment): Add new bool argument.
8362 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
8363 (PERCENT_END_HEADER): ... this.
8364 (PERCENT_BEFORE_DEFINITIONS): Update to...
8365 (PERCENT_START_HEADER): ... this.
8366 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
8367 * tests/actions.at (Printers and Destructors): Update names.
8368
8369 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
8370
8371 Add comparison operators for C++ location classes. Discussed at
8372 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
8373 * data/c++.m4 (b4_define_location_comparison): New boolean %define
8374 declaration indicating whether filename_type has an operator==. If
8375 filename_type is `std::string', it defaults to `1', `0' otherwise.
8376 * data/location.cc: Iff b4_define_location_comparison is `1', add
8377 operator== and operator!= for class position and for class location.
8378
8379 Some minor fixes.
8380 * src/scan-action.l: Remove unused file.
8381 * src/symtab.c (symbol_printer_set): Use printer_location not
8382 destructor_location.
8383 * src/symtab.h (struct symbol): Replace incorrect source comment for
8384 printer members.
8385 * tests/input.at (Incompatible Aliases): Update output with correct
8386 printer location.
8387
8388 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
8389
8390 Don't put the pre-prologue in the header file. For the yacc.c code
8391 file and the glr.c header and code files, move the pre-prologue before
8392 the token definitions. Add new %before-definitions and
8393 %after-definitions to declare code that will go in both the header file
8394 and code file. Discussed at
8395 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
8396 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
8397 and
8398 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
8399 * NEWS (2.3+): Describe these changes.
8400 * data/glr.c (b4_pre_prologue): Move from within to before...
8401 (b4_shared_declarations): ... this.
8402 Add new b4_before_definitions before b4_token_enums.
8403 Add new b4_after_definitions at the end.
8404 * data/glr.cc (b4_pre_prologue): Replace with...
8405 (b4_before_definitions): ... this in the header file.
8406 (b4_after_definitions): New near the end of the header file.
8407 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
8408 code file right before including the header file.
8409 (b4_before_definitions): New in the previous position of
8410 b4_pre_prologue in the header file.
8411 (b4_after_definitions): New near the end of the header file.
8412 * data/yacc.c: Clean up some m4 quoting especially in the header file.
8413 (b4_token_enums_defines): In the code file, move to right before
8414 YYSTYPE for consistency with the header file.
8415 (b4_before_definitions): New right before b4_token_enums_defines in
8416 both the header and code file.
8417 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
8418 header and code file.
8419 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
8420 of prologues for %union dependencies.
8421 (Decl Summary): In %defines description, mention the effect of
8422 %before-definitions and %after-definitions on the header file.
8423 (Calc++ Parser): Forward declare driver in a %before-definitions rather
8424 than in the pre-prologue so that make check succeeds.
8425 (Table of Symbols): Add entries for %before-definitions and
8426 %after-definitions.
8427 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
8428 %before-definitions.
8429 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
8430 (declaration): Parse those declarations and append to
8431 b4_before_definitions and b4_after_definitions, respectively.
8432 * src/reader.c (before_definitions, after_definitions): New bools to
8433 track whether those declarations have been seen.
8434 (prologue_augment): Add to the post-prologue if %union,
8435 %before-definitions, or %after-definitions has been seen.
8436 * src/reader.h (before_definitions, after_definitions): New extern's.
8437 * src/scan-gram.l: Scan the new declarations.
8438 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
8439 prologue block in a %before-definitions or a %after-definitions based
8440 on whether the %union is declared.
8441 * tests/regression.at (Early token definitions with --yacc, Early token
8442 definitions without --yacc): Move tests for token definitions into the
8443 post-prologue since token names are no longer defined in the
8444 pre-prologue.
8445
8446 2006-06-20 Akim Demaille <akim@epita.fr>
8447
8448 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
8449 (symbol_get): Use it.
8450 * src/parse-gram.y: Use it.
8451
8452 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
8453
8454 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
8455 build succeeds when configured with --enable-gcc-warnings.
8456
8457 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
8458
8459 * src/parse-gram.y (char_name): New function.
8460 (CHAR, STRING, string_content): For %printer, properly escape.
8461 (ID): Prefer fputs to fprintf.
8462 (id): Reindent to be consistent with other rules.
8463 Properly quote char.
8464
8465 The Translation Project changed its way of publishing translations
8466 to maintainers. I haven't received any responses to my request
8467 for supporting the old way, or for documenting the new way. I
8468 have modified 'bootstrap' to use screen scraping
8469 (in this case, HTML scraping). This is unreliable and inelegant,
8470 but I don't see any better way. Yuck.
8471 * bootstrap (TP_URL, WGET_COMMAND): New vars.
8472 (get_translations): New function, which uses HTML scraping to
8473 deduce locations of latest translations.
8474 Use this function to grab both bison and bison-runtime .po files.
8475 Don't bother priming the pump for the runtime-po domain any more,
8476 as it's now translated better than bison is.
8477
8478 2006-06-19 Akim Demaille <akim@epita.fr>
8479
8480 * src/scan-gram.l: No longer "parse" things after `%union' until
8481 `{'. Rather, return a single "%union" token.
8482 No longer make symbols: return strings, and leave the conversion
8483 to symbols to the parser.
8484 (SC_PRE_CODE, token_type): Remove.
8485 * src/parse-gram.y (%union): New field `character'.
8486 Sort tokens.
8487 (CHAR): New token.
8488 (ID, ID_COLON): Now that the scanner no longer makes them
8489 identifiers, adjust all uses to invoke symbol_get.
8490 (id_colon): New, wraps the conversion from string to symbol.
8491 (%union): Accept a possible union_name.
8492 (symbol): Now can be a char.
8493 * data/c.m4 (b4_union_name): Leave a default value.
8494 * data/glr.c, data/yacc.c: Use it.
8495
8496 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
8497
8498 For associating token numbers with token names for "yacc.c", don't use
8499 #define statements unless `--yacc' is specified; always use enum
8500 yytokentype. Most important discussions start at:
8501 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
8502 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
8503 and
8504 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
8505 * NEWS (2.3+): Mention.
8506 * data/c.m4 (b4_yacc_if): New.
8507 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
8508 token #define's.
8509 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
8510 on token name definitions.
8511 * src/getargs.c (usage): Capitalize `Yacc' in English.
8512 * src/output.c (prepare): Define b4_yacc_flag.
8513 * tests/regression.at (Early token definitions): Test that tokens names
8514 are defined before the pre-prologue not just before the post-prologue.
8515 Remove this test case and copy to...
8516 (Early token definitions with --yacc): ... this to test #define's.
8517 (Early token definitions without --yacc): ... and this to test enums.
8518
8519 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
8520
8521 * NEWS: Reword the post-2.3 change to not be so optimistic about
8522 removing the old "look-ahead" spelling.
8523 Update previous look-ahead/lookahead change reports.
8524 * REFERENCES: look-ahead -> lookahead (since that's
8525 what he actually wrote).
8526 * doc/refcard.tex: look ahead -> lookahead,
8527 look-ahead -> lookahead
8528
8529 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
8530
8531 For consistency, use `lookahead' instead of `look-ahead' or
8532 `look_ahead'. Discussed starting at
8533 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
8534 and then at
8535 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
8536 * NEWS: For the next release, note the change to `--report'.
8537 * TODO, doc/bison.1: Update English.
8538 * doc/bison.texinfo: Update English.
8539 (Understanding Your Parser, Bison Options): Document as
8540 `--report=lookahead' rather than `--report=look-ahead'.

8548 * src/getargs.c (report_args): Move "lookahead" before alternate
8549 spellings.
8550 (report_types): Update uses.

8554 report_look_ahead_tokens.
8555 * src/lalr.c: Update English in comments.

8559 Rename local n_look_ahead_tokens to n_lookahead_tokens.
8560 (lookahead_tokens_print): Rename from look_ahead_tokens_print.
8561 Rename local n_look_ahead_tokens to n_lookahead_tokens.
8562 Update other uses.
8563 Update English in output.
8564 (add_lookback_edge, initialize_LA, lalr, lalr_free): Update uses.
8565 * src/print.c: Update English in comments.
8566 (lookahead_set): Rename from look_ahead_set.
8567 (print_reduction): Rename argument lookahead_token from
8568 look_ahead_token.

8605
8606 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
8607
8608 * TODO: Add request from Nelson H. F. Beebe to be able to install
8609 Bison without installing the yacc script.
8610
8611 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
8612
8613 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
8614 and yytext if they're already #define'd.
8615 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
8616 * src/scan-code-c.c: ... here.
8617 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
8618 <config.h>.
8619
8620 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
8621
8622 Get Bison to build again when configured with --enable-gcc-warnings.
8623 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
8624 missing #include's.
8625 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
8626 loc argument as it shadows a global.
8627 * src/scan-gram.l: Remove stray comma that prevents boundary_set
8628 invocation.
8629
8630 * src/.cvsignore: Add scan-code.c.
8631
8632 2006-06-07 Akim Demaille <akim@epita.fr>
8633

8635 to...
8636 * src/scan-code.l: here.
8637 * tests/input.at (Torturing the Scanner): Fix another location
8638 error.
8639
8640 2006-06-07 Akim Demaille <akim@epita.fr>
8641
8642 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
8643
8644 2006-06-06 Akim Demaille <akim@epita.fr>
8645
8646 Extract the parsing of user actions from the grammar scanner.
8647 As a consequence, the relation between the grammar scanner and
8648 parser is much simpler. We can also split "composite tokens" back
8649 into simple tokens.
8650 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
8651 * src/scan-gram.l (add_column_width, adjust_location): Move to and
8652 rename as...
8653 * src/location.h, src/location.c (add_column_width)
8654 (location_compute): these.
8655 Fix the column count: the initial column is 0.
8656 (location_print): Be robust to ending column being 0.
8657 * src/location.h (boundary_set): New.
8658 * src/main.c: Adjust to scanner_free being renamed as
8659 gram_scanner_free.
8660 * src/output.c: Include scan-code.h.
8661 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
8662 Use boundary_set.
8663 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
8664 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
8665 which is now, again, a separate token.
8666 Adjust all dependencies.
8667 Whereever actions with $ and @ are used, use translate_code.
8668 (action): Remove this nonterminal which is now useless.
8669 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
8670 (grammar_current_rule_action_append): Use translate_code.
8671 (packgram): Bound check ruleno, itemno, and rule_length.
8672 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
8673 (last_string, last_braced_code_loc, max_left_semantic_context)
8674 (scanner_initialize, scanner_free, scanner_last_string_free)
8675 (gram_out, gram_lineno, YY_DECL_): Move to...
8676 * src/scan-gram.h: this new file.
8677 (YY_DECL): Rename as...
8678 (GRAM_DECL): this.
8679 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
8680 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8681 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8682 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8683 Move these declarations, and...
8684 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
8685 these to...
8686 * src/flex-scanner.h: this new file.
8687 * src/scan-gram.l (rule_length, rule_length_overflow)
8688 (increment_rule_length): Remove.
8689 (last_braced_code_loc): Rename as...
8690 (gram_last_braced_code_loc): this.
8691 Adjust to the changes of the parser.
8692 Move all the handling of $ and @ into...
8693 * src/scan-code.l: here.
8694 * src/scan-gram.l (handle_dollar, handle_at): Remove.
8695 (handle_action_dollar, handle_action_at): Move to...
8696 * src/scan-code.l: here.
8697 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
8698 scan-code.h, scan-code-c.c, scan-gram.h.
8699 (EXTRA_bison_SOURCES): Add scan-code.l.
8700 (BUILT_SOURCES): Add scan-code.c.
8701 (yacc): Be robust to white spaces.

8704 * tests/regression.at: Adjust the column numbers.
8705 * tests/regression.at: Adjust the error message.
8706
8707 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
8708
8709 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
8710 Use Akim's wording from
8711 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
8712
8713 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
8714
8715 Between Bison releases, manually append `+' to the previous Bison
8716 release number, and use that as a signal to automatically print the
8717 ChangeLog's CVS Id keyword from --version. Discussed starting at
8718 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
8719 * ChangeLog: Add Id header.
8720 * configure.ac (AC_INIT): Append `+' to `2.3'.
8721 * src/.cvsignore: Add revision.c.
8722 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
8723 (BUILT_SOURCES): Add revision.c.
8724 (revision.c): New target rule. This file defines a new global variable
8725 named revision. It initializes it with either the Id from ChangeLog
8726 or, if VERSION doesn't contain `+', with the empty string.
8727 * src/getargs.c (version): Print the value of revision.
8728 * src/revision.h: Extern revision.
8729
8730 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
8731
8732 * NEWS: Version 2.3.
8733 * configure.ac (AC_INIT): Likewise.
8734
8735 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
8736
8737 * data/glr.c (YYRECOVERING): Define to be a function-like macro
8738 with no arguments, not as an object-like macro. This is for
8739 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
8740 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
8741 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
8742 Document this.
8743
8744 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
8745
8746 * src/getargs.c (usage): Back out yesterday's modification of the
8747 --help output so that we don't have to wait for translation before
8748 releasing 2.3.
8749
8750 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
8751
8752 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
8753 Problem reported by Akim Demaille.
8754
8755 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
8756
8757 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
8758
8759 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
8760
8761 * data/yacc.c (yy_reduce_print): Omit trailing white space in
8762 generated source code. Problem reported by Frans Englich in
8763 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
8764
8765 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
8766
8767 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
8768 shell, not within 'make', so that 'make' by an ordinary builder
8769 (using GNU make) does not worry about configuring gzip. This also
8770 works around a bug reported independently by Keith Thompson and by
8771 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
8772 stderr rather than stdout, messing up the build logs.
8773
8774 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
8775
8776 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
8777 to make sure that YYID will never be unused. This fixes a 'make
8778 maintainer-check' failure caused by the recent changes to the 'Trivial
8779 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
8780 not used.
8781 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
8782
8783 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
8784
8785 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
8786 state before an empty RHS is always resolved here. Only the location
8787 of that state is guaranteed to be resolved, and that's enough. This
8788 fixes the remaining bug reported by Derek M. Jones in
8789 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
8790 * tests/glr-regression.at (Uninitialized location when reporting
8791 ambiguity): Test the above case.
8792 Also, the embedded comments in this test case claim it checks the case
8793 of an empty RHS that has inherited the initial location. However, the
8794 corresponding LHS was already resolved, so yyresolveLocations didn't
8795 actually have reason to modify it. Fix this by forcing
8796 nondeterministic operation at the beginning of the parse.
8797
8798 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
8799
8800 * data/c.m4 (b4_yy_symbol_print_generate):
8801 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
8802 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
8803 of the bugs reported today by Derek M Jones in
8804 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
8805 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
8806 defined to be a type name without parens or brackets.
8807 (Location Type): Similarly for YYLTYPE.
8808 * tests/regression.at (Trivial grammars): Put in a test for this
8809 bug that will be caught by 'make maintainer-check' (though not,
8810 alas, by 'make check' unless your compiler is picky).
8811
8812 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
8813
8814 * NEWS: Version 2.2.
8815 * configure.ac (AC_INIT): Likewise.
8816
8817 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
8818
8819 * data/glr.c (yyreportTree): Make room in yystates for the state
8820 preceding the RHS. This fixes the segmentation fault reported by Derek
8821 M. Jones in
8822 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
8823 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
8824 to the user. Reported for yyreportTree by Derek M. Jones later in the
8825 same thread.
8826 * THANKS: Add Derek M. Jones.
8827 Update my email address.
8828 Fix typo in Steve Murphy's name.
8829
8830 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
8831
8832 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
8833 checking against YYLAST that caused the parser to miss a potential
8834 alternative in its diagnostic.
8835 Problem reported by Maria Jose Moron Fernandez in
8836 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
8837 * data/lalr1.cc (yysyntax_error_): Likewise.
8838 * data/yacc.c (yysyntax_error): Likewise.
8839 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
8840 tokens, in case we run into an older C compiler.
8841 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
8842 Use them to check for the off-by-one error fixed above.
8843
8844 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
8845 YYSIZE_T, not size_t.
8846 * tests/regression.at (Trivial grammars): New test, to catch
8847 the error fixed by the above patch.
8848
8849 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8850
8851 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
8852 scheme.
8853 Reported by Steve Murphy.
8854
8855 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8856
8857 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
8858 * data/glr.cc: b4_location_flag is now b4_locations_flag.
8859
8860 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8861
8862 Implement --trace=m4.
8863 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
8864 * src/output.c (output_skeleton): When set, pass -dV to m4.
8865
8866 Factor the handling of flags in m4.
8867 * src/output.c (prepare): Rename the muscle names debug, defines,
8868 error_verbose to debug_flag, defines_flag, error_verbose_flag.
8869 * data/c.m4: Adjust.
8870 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
8871 Use b4_define_flag_if to define other b4_FLAG_if macros.
8872 (b4_location_if): As a consequence, rename as...
8873 (b4_locations_if): this, for consistency.
8874 Adjust all the skeletons.
8875
8876 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
8877
8878 * etc/bench.pm: Shorten bench names.

8884 Sort the flags.
8885 Adjust dependencies.
8886
8887 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
8888
8889 * data/c.m4 (b4_copyright): Put the special exception for Bison
8890 skeletons here, so we don't have to put it in each skeleton. All
8891 uses changed. Suggested by Akim Demaille. Also, wrap the
8892 copyright notice, in case it is longer than 80 columns. Replace
8893 comma by newline after title.
8894
8895 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
8896
8897 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
8898 incompatibility, not a bug. Mention that it wasn't fixed as of
8899 flex 2.5.33.
8900
8901 2006-05-11 Akim Demaille <akim@lrde.epita.fr>

8910 with the member "token".
8911 Reported by Martin Nylin.
8912
8913 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
8914

8928 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
8929
8930 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
8931 that variable and the line breaks the bootstrap. Problem reported
8932 by Juan M. Guerrero.

8957 and didn't really work.
8958 For the index, use @ifnotinfo, not @iftex.
8959 Minor cleanups of spacing and terminology.

8965
8966 2006-03-12 Akim Demaille <akim@lrde.epita.fr>

8969 The test suite already exercize these cases.
8970 * data/c++.m4 (b4_namespace): New.
8971 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

8994 * data/c.m4 (b4_token_enum): Always define the enum of tokens,
8995 even if empty.
8996 * data/lalrl1.cc, data/glr.cc (parser::token_type): New.
8997 * doc/bison.texinfo (Calc++ Scanner): Use it.
8998
8999 2006-03-09 Paul Eggert <eggert@cs.ucla.edu>
9000
9001 Fix two nits reported by twlevo, plus one more that I discovered.
9002
9003 * src/assoc.h (assoc_to_string): Give a name to the arg, as
9004 this is the usual Bison style.
9005 * src/location.h (location_print): Likewise.
9006
9007 * src/reader.h (token_name): Likewise.
9008
9009 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
9010
9011 Fix some nits reported by twlevo.
9012 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
9013 and "POSIX". Use more-modern syntax for URLs. Mention C++
9014 and ask for Java. Don't hardwire OS version numbers. Add
9015 copyright notice.
9016 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
9017 * src/conflicts.c (solved_conflicts_obstack): Now static.
9018
9019 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
9020
9021 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
9022 page. Say "you can use it" not "you may use it" as on the web page;
9023 we're describing capabilities not granting permission.
9024
9025 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
9026
9027 * data/glr.c (yyresolveLocations): Rename local variables to avoid
9028 shadowing warnings. Use usual patter for iterating through RHS.
9029 * tests/glr-regression.at
9030 (Uninitialized location when reporting ambiguity):
9031 Modify yylex so that it uses its argument, rather than trying
9032 to rely on ARGSUSED (which doesn't work for gcc with warnings).
9033 const char -> char const.
9034
9035 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
9036 Don't use tabs inside commands; it messes up 'ps'.
9037 Problem reported by twlevo.
9038
9039 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
9040
9041 * tests/glr-regression.at (Uninitialized location when reporting
9042 ambiguity): New test case.
9043 * data/glr.c (yyresolveLocations): New function, which uses
9044 YYLLOC_DEFAULT.
9045 (yyresolveValue): Invoke yyresolveLocations before reporting an
9046 ambiguity.
9047 * doc/bison.texinfo (Default Action for Locations): Note
9048 YYLLOC_DEFAULT's usage for ambiguity locations.
9049 (GLR Semantic Actions): Cross-reference those notes.
9050
9051 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
9052
9053 * tests/glr-regression.at (Leaked semantic values when reporting
9054 ambiguity): Remove unnecessary union and type declarations.
9055 (Leaked lookahead after nondeterministic parse syntax error): New test
9056 case.
9057 * data/glr.c (yyparse): Check for zero stacks remaining before
9058 attempting to shift the lookahead so that you don't lose it.
9059
9060 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
9061
9062 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
9063 * tests/glr-regression.at (Leaked semantic values when reporting
9064 ambiguity): New test case.
9065 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
9066 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
9067 now unnecessary yystackp parameter.
9068 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
9069 destructors can be called.
9070
9071 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
9072 in existing testcases.
9073
9074 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
9075
9076 Don't leak semantic values for parent RHS when a user action cuts the
9077 parser, and clean up related code a bit.
9078 * tests/glr-regression.at (Leaked merged semantic value if user action
9079 cuts parse): Rename to...
9080 (Leaked semantic values if user action cuts parse): ... this. Add check
9081 for leaked parent RHS values.
9082 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
9083 between an unresolved state (non-empty chain of semantic options) and
9084 an incomplete one (signaled by an empty chain).
9085 (yyresolveStates): Document the interface. Move all manipulation of a
9086 successfully or unsuccessfully resolved yyGLRState to...
9087 (yyresolveValue): ... here so that yyresolveValue always leaves a
9088 yyGLRState with consistent data and thus is easier to understand.
9089 Remove the yyvalp and yylocp parameters since they are always just
9090 taken from the yys parameter. When reporting a discarded merged value
9091 in debugging output, note that it is incompletely merged. Document the
9092 interface.
9093 (yyresolveAction): If resolving any of the RHS states fails, destroy
9094 them all rather than leaking them. Thus, as long as user actions are
9095 written to clean up the RHS correctly, yyresolveAction always cleans up
9096 the RHS of a semantic option. Document the interface.
9097
9098 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
9099
9100 * data/glr.c (yyexpandGLRStack): Catch an off-by-one error that
9101 led to a segmentation fault in GNU Pascal. Problem reported
9102 by Waldek Hebisch.
9103
9104 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>
9105
9106 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
9107 mid-rule action inside a nonterminal symbol in order to declare a
9108 destructor for its semantic value.
9109
9110 2006-02-16 Paul Eggert <eggert@cs.ucla.edu>
9111
9112 * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
9113 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
9114 __cplusplus && ! defined _STDLIB_H && !
9115 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
9116 defined free))]: Include <stdlib.h> rather than rolling our own
9117 declarations of malloc and free, to avoid problems with
9118 incompatible declarations (using 'throw') C++'s stdlib.h. This
9119 should fix Debian bug 340012
9120 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
9121 reported by Guillaume Melquiond.

9125 * NEWS: Clarify symbols versus types in unused-value warnings.

9127 * configure.ac (AC_INIT): Bump version number.
9128
9129 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
9130
9131 * NEWS: Version 2.1a.
9132 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
9133 since C99 requires this.
9134
9135 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
9136
9137 * m4/c-working.m4: New file.
9138 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
9139
9140 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>
9141
9142 * Makefile.maint: Merge from coreutils.

9146 More portability fixes for problems summarized by Nelson H. F. Beebe.
9147
9148 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
9149 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
9150 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
9151 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
9152 messes up because C++ code is compiled in 32-bit mode but linked
9153 in 64-bit mode.

9157 More portability fixes for problems summarized by Nelson H. F. Beebe.
9158
9159 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
9160 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
9161
9162 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
9163 nodist_PROGRAMS, since we don't need to actually compile the
9164 example if we're just doing a plain 'make'. This avoids bothering
9165 the installer unnecessarily about problems due to weird C++
9166 compilers.
9167

9169
9170 More portability fixes for problems summarized by Nelson H. F. Beebe.
9171
9172 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
9173 than #include "...", and compile with -I'.'. The old method was
9174 not portable, according to Posix and the C standard, and it does
9175 not work with Sun C 5.7, where previous #line directives affect
9176 the working directory used in later #include "..." directives.

9184 More portability fixes for problems summarized by Nelson H. F. Beebe.
9185
9186 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
9187 '#include <map>' works and that you can apply ++ to iterators.
9188
9189 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>

9191 Work around portability problems summarized by Nelson H. F. Beebe in
9192 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
9193
9194 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
9195 that '#include <string>' works.
9196
9197 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
9198 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
9199 "warning: sorry: semantics of inline function static data `const
9200 unsigned char translate_table[262]' are wrong (you'll wind up with
9201 multiple copies)".
9202
9203 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
9204 or, xor to not_, and_, or_, and xor_, respectively. This works
9205 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
9206 random system header somewhere that includes the equivalent of
9207 <iso646.h>.
9208
9209 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
9210 -E" works; it apparently doesn't work with PathScale EKO Compiler
9211 Suite Version 2.0.
9212
9213 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
9214
9215 During deterministic GLR operation, user actions should be able to
9216 influence the parse by changing yychar. To make this easier to fix and
9217 to make glr.c easier to evolve in general, don't maintain yytoken in
9218 parallel with yychar; just compute yytoken when needed.
9219 * tests/glr-regression.at (Incorrect lookahead during deterministic
9220 GLR): Check that setting yychar in a user action has the intended
9221 effect.
9222 * data/glr.c (yyGLRStack): Remove yytokenp member.
9223 (yyclearin): Don't set *yytokenp.
9224 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
9225 yychar rather than *yytokenp to determine the current lookahead.
9226 Compute yytoken locally when needed.
9227 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
9228 point to.
9229
9230 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
9231 after `--report' documentation.
9232
9233 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
9234
9235 * src/parse-gram.y (grammar_declaration): Location of printer
9236 symbol is @1, not list->location. Bug reported by twlevo.
9237 * tests/input.at (Incompatible Aliases): Adjust to above change.
9238
9239 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
9240
9241 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
9242 all the test at once. This makes the output easier to read in the
9243 normal case.
9244
9245 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
9246 got from <http://bro-ids.org/download.html>. The bug is that
9247 when two actions appeared in succession, the second one was
9248 scanned before the first one was added to the grammar rule
9249 as a midrule action. Bison then output the incorrect warning
9250 "parse.y:905.17-906.36: warning: unused value: $3".
9251 * src/parse-gram.y (BRACED_CODE, action): These are no longer
9252 associated with a value.
9253 (rhs): Don't invoke grammar_current_rule_action_append.
9254 (action): Invoke it here instead.
9255 * src/reader.c (grammar_midrule_action): Now extern.
9256 (grammar_current_rule_action_append): Don't invoke
9257 grammar_midrule_action; that is now the scanner's job.
9258 * src/reader.h (last_string, last_braced_code_loc):
9259 (grammar_midrule_action): New decls.
9260 * src/scan-gram.l (last_string): Now extern, sigh.
9261 (last_braced_code_loc): New extern variable.
9262 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
9263 rule already has an action.
9264 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
9265 * tests/input.at (AT_CHECK_UNUSED_VALUES):
9266 Add some tests to check that the above changes fixed the bug.
9267
9268 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
9269
9270 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
9271 All used changed. Check whether the symbol has a destructor,
9272 not whether it is typed.
9273 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
9274 that the values are still reported as unused. All line numbers
9275 adjusted.
9276
9277 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
9278
9279 Work around a bug in bro 0.8, which underparenthesizes its
9280 definition of YYLLOC_DEFAULT.
9281 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
9282 their arguments.
9283 * data/lalr1.cc: Likewise.
9284 * data/yacc.cc: Likewise.
9285
9286 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
9287
9288 Work around a bug in Pike 7.0, and give the Pike folks a
9289 better way to override the usual int widths.
9290 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
9291 user can override the types.
9292 (short): #undef, to work around a bug in Pike 7.0.
9293 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
9294 (union yyalloc.yyss): Use yytype_int16 rather than short.
9295 All uses changed.
9296 (yysigned_char): Remove.
9297 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
9298 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
9299 * tests/regression.at (Web2c Actions): Adjust to above changes.
9300
9301 * src/reader.c (check_and_convert_grammar): New function.
9302 (reader): Close the input file even if something went wrong during
9303 parsing. Minor file descriptor leak reported by twlevo.
9304
9305 * src/assoc.c (assoc_to_string): Use a default: abort (); case
9306 to pacify gcc -Wswitch-default.
9307 * src/scan-gram.l (adjust_location): Use a default: break; case
9308 to pacify gcc -Wswitch-default.
9309 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
9310 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
9311 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
9312 Move these decls to scan-skel.l, since they don't need to be
9313 visible elsewhere.
9314 * src/scan-skel.l: Accept the above decls.
9315 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
9316 is used.
9317
9318 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
9319
9320 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
9321 since we don't want to insist on a version number at the start
9322 of the changelog every time.
9323 * Makefile.maint: Sync from coreutils a bit better.
9324 (sc_trailing_blank): Renamed from sc_trailing_space.
9325 All uses changed.
9326 (sc_no_if_have_config_h, sc_require_config_h):
9327 (sc_prohibit_assert_without_use): New rules.
9328 (sc_obsolete_symbols): Don't catch Makefile.maint itself.
9329 (sc_dd_max_sym_length): Fix leading spaces in rule.
9330 (sc_system_h_headers): Prefix with @.
9331 (sc_useless_cpp_parens, m4-check): Output line numbers.
9332 (changelog-check): Allow version only in head.
9333 * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
9334 satisfy new Makefile.maint rule.

9376 2006-01-20 Paul Eggert <eggert@cs.ucla.edu>
9377
9378 Be a bit more systematic about using 'abort'.
9379 * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
9380 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
9381 Put 'default: abort ();' before some other case, to satisfy older
9382 pedantic compilers.
9383 * lib/bitset_stats.c (bitset_stats_init): Likewise.
9384 * lib/ebitset.c (ebitset_elt_find, ebitset_op3_cmp): Likewise.

9390 (get_linestyle_str, get_arrowstyle_str): Likewise.
9391 * src/conflicts.c (resolve_sr_conflict):
9392 Use a default case rather than one for the one remaining enum
9393 value, to catch invalid enum values as well.
9394 * src/lalr.c (set_goto_map, map_goto):
9395 Prefer "assert (FOO);" to "if (!FOO) abort ();".
9396 * src/nullable.c (nullable_compute, token_definitions_output):
9397 Likewise.

9407 (assert): New macro.
9408
9409 * doc/bison.texinfo (Prologue, Rules, Actions, Union Decl, Action Decl):
9410 (Destructor Decl, Parser Function, Pure Calling):

9413 2006-01-19 Paul Eggert <eggert@cs.ucla.edu>
9414
9415 Fix some porting glitches found by Nelson H. F. Beebe.
9416 * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
9417 compilers that don't understand that abort () does not return.
9418 * src/state.c (transitions_to): Likewise.
9419 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
9420 that '#include <cstdlib>' works.
9421 * src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
9422 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
9423 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
9424 for the benefit of some pre-C99 compilers.
9425
9426 * bootstrap: Undo changes to gnulib files that autoreconf made.
9427
9428 Minor fixups to get 'make maintainer-check' to work.
9429 * configure.ac: Don't use -Wnested-externs, as it's incompatible
9430 with the new verify.h implementation.
9431 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
9432 * data/glr.c (YYUSE): Depend on __GNUC__ as well.
9433 * data/yacc.c (YYUSE): Likewise.
9434 * data/lalr1.cc (yysyntax_error_): YYUSE (yystate).
9435 * lib/subpipe.c (end_of_output_subpipe): The args are unused.
9436 * src/parse-gram.y (declaration): Don't pass a string constant
9437 to a function that expects char *, since GCC might complain
9438 about the constant value.
9439 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
9440 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
9441 before #defining them.
9442 * tests/glr-regression.at
9443 (Incorrectly initialized location for empty right-hand side in GLR):
9444 In yyerror, use the msg arg.
9445 (Corrupted semantic options if user action cuts parse):
9446 (Incorrect lookahead during deterministic GLR):
9447 (Incorrect lookahead during nondeterministic GLR):
9448 Don't name a local var 'index'; it shadows string.h's 'index'.
9449
9450 2006-01-19 Akim Demaille <akim@epita.fr>
9451
9452 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
9453 location, not just parts of it.
9454
9455 2006-01-18 Paul Eggert <eggert@cs.ucla.edu>
9456
9457 * NEWS: Document the fact that multiple %unions are now allowed.
9458 * doc/bison.texinfo (Union Decl): Likewise.
9459 * TODO: This feature is now implemented, so remove it from
9460 the wishlist.
9461
9462 * Makefile.maint: Merge with coreutils Makefile.maint.
9463 (CVS_LIST): Use build-aux version if available.
9464 (VERSION_REGEXP): New macro.
9465 (syntax-check-rules): Add sc_no_if_have_config_h,
9466 sc_prohibit_assert_without_use, sc_require_config_h,
9467 sc_useless_cpp_parens.
9468 (sc_obsolete_symbols): Check for O_NDELAY.
9469 (sc_dd_max_sym_length): Track coreutils.
9470 (sc_unmarked_diagnostics): Look in all files, not just *.c.
9471 (sc_useless_cpp_parens): New rule.
9472 (news-date-check): Look for version or today's date.
9473 (changelog-check): Don't require version number near head.
9474 (copyright-check): Use current year instead of hardwiring 2005.
9475 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
9476 (announcement): Add --gpg-key-ID.
9477
9478 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
9479 with "file system".
9480
9481 Avoid undefined behavior that addressed just before the start of an
9482 array. Problem reported by twlevo.
9483 * src/reader.c (packgram): Prepend a new sentinel before ritem.
9484 * src/lalr.c (build_relations): Rely on new sentinel.
9485 * src/gram.c (gram_free): Adjust to new sentinel.
9486
9487 2006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
9488
9489 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
9490 yylookaheadNeeds. All uses updated.
9491 (yysplitStack): Rename local yynewLookaheadStatuses to
9492 yynewLookaheadNeeds.
9493 * data/glr-regression.at (Incorrect lookahead during nondeterministic
9494 GLR): In comments, change `lookahead status' to `lookahead need'.
9495
9496 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9497
9498 * data/glr.c (yysplitStack): A little stylistic rewrite.
9499
9500 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
9501
9502 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
9503
9504 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
9505
9506 * doc/bison.texinfo: Fix some typos.
9507 (GLR Semantic Actions): New subsection discussing special
9508 considerations because GLR semantic actions might be deferred.
9509 (Actions): Mention look-ahead usage of yylval.
9510 (Actions and Locations): Mention look-ahead usage of yylloc.
9511 (Special Features for Use in Actions): Add YYEOF entry and mention it
9512 in the yychar entry.
9513 In the yychar entry, remove mention of the local yychar case (pure
9514 parser) since this is irrelevant information when writing semantic
9515 actions and since it's already discussed in `Table of Symbols' where
9516 yychar is otherwise described as an external variable.
9517 In the yychar entry, don't call it the `current' look-ahead since it
9518 isn't when semantic actions are deferred.
9519 In the yychar and yyclearin entries, add note about deferred semantic
9520 actions.
9521 Add yylloc and yylval entries discussing look-ahead usage.
9522 (Look-Ahead Tokens): When discussing yychar, don't call it the
9523 `current' look-ahead, and do mention yylval and yylloc.
9524 (Error Recovery): Cross-reference `Action Features' when mentioning
9525 yyclearin.
9526 (Table of Symbols): In the yychar entry, don't call it the `current'
9527 look-ahead.
9528 In the yylloc and yylval entries, mention look-ahead usage.
9529
9530 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
9531
9532 * tests/glr-regression.at: Update copyright year to 2006.
9533
9534 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
9535
9536 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
9537 use during nondeterministic operation to track which stacks have
9538 actually needed the current lookahead.
9539 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
9540 Allocate, deallocate, resize, and otherwise shuffle space for
9541 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
9542 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
9543 appropriately during nondeterministic operation.
9544 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
9545 members to store the current lookahead to be used by the deferred
9546 user action.
9547 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
9548 from which the RHS is taken. Set the lookahead members of the new
9549 yySemanticOption according to the lookahead status for stack yyk.
9550 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
9551 yyaddDeferredAction.
9552 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
9553 members of yySemanticOption before invoking yyuserAction, and then set
9554 them back to their current values afterward.
9555 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
9556 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
9557 * tests/glr-regression.at: Remove `.' from the ends of recent test case
9558 titles for consistency.
9559 (Leaked merged semantic value if user action cuts parse): In order to
9560 suppress lint warnings, use arguments in merge function, and assign
9561 char value < 128 in main.
9562 (Incorrect lookahead during deterministic GLR): New test case.
9563 (Incorrect lookahead during nondeterministic GLR): New test case.
9564
9565 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
9566
9567 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
9568 !yyvaluep as signal that no semantic value is available to print.
9569 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
9570 to print a semantic value.
9571
9572 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
9573
9574 * tests/glr-regression.at: For consistency with my newer test cases,
9575 don't thank myself.
9576
9577 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
9578
9579 * data/glr.c (yyresolveValue): When merging semantic options, if at
9580 least one user action succeeds but a later one cuts the parse, then
9581 destroy the semantic value before returning rather than leaking it.
9582 (yyresolveStates): If a user action cuts the parse and thus
9583 yyresolveValue fails, ignore the (unset) semantic value rather than
9584 corrupting the yyGLRState, and empty the semantic options list since
9585 the user actions should have called all necessary destructors.
9586 Simplify code with YYCHK.
9587 * tests/glr-regression.at (Corrupted semantic options if user action
9588 cuts parse): New test case.
9589 (Undesirable destructors if user action cuts parse): New test case.
9590 Before applying any of this patch, this test case never actually failed
9591 for me... but only because the corrupted semantic options usually
9592 masked this bug.
9593 (Leaked merged semantic value if user action cuts parse): New test
9594 case.
9595
9596 2006-01-05 Akim Demaille <akim@epita.fr>
9597
9598 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

9600 2006-01-04 Paul Eggert <eggert@cs.ucla.edu>
9601
9602 * data/c.m4 (b4_c_modern): New macro, with a new provision for
9603 _MSC_VER. Problem reported by Cenzato Marco.
9604 (b4_c_function_def): Use it.
9605 * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
9606 b4_c_modern.
9607 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
9608 than rolling our own.
9609
9610 2006-01-04 Akim Demaille <akim@epita.fr>
9611
9612 Also warn about non-used mid-rule values.
9613 * src/symlist.h, src/symlist.c (symbol_list): Add a mid_rule
9614 member.
9615 (symbol_list_new): Adjust.
9616 * src/reader.c (symbol_typed_p): New.
9617 (grammar_rule_check): Use it.
9618 (grammar_midrule_action): Bind a mid-rule LHS to its rule.
9619 Check its rule.
9620 * tests/input.at (AT_CHECK_UNUSED_VALUES): New.
9621 Use it.
9622 * tests/actions.at (Exotic Dollars): Adjust.
9623
9624 2006-01-04 Akim Demaille <akim@epita.fr>
9625
9626 * src/reader.c (grammar_midrule_action): If $$ is set in a
9627 mid-rule, move the `used' bit to its lhs.
9628 * tests/input.at (Unused values): New.
9629 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
9630
9631 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
9632
9633 * doc/bison.texinfo (Bison Options): Say more accurately what
9634 --yacc does.
9635 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
9636 about declarations in the grammar when in Yacc mode, as POSIX does
9637 not require a diagnostic when the grammar uses extensions.
9638
9639 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
9640
9641 Warn about dubious constructions like "%token T T".
9642 Reported by twlevo.
9643 * src/symtab.h (struct symbol.declared): New member.
9644 * src/symtab.c (symbol_new): Initialize it to false.
9645 (symbol_class_set): New arg DECLARING, specifying whether
9646 this is a declaration that we want to warn about, if there
9647 is more than one of them. All uses changed.
9648
9649 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
9650 Allow multiple %union directives, whose contents concatenate.
9651 * src/parse-gram.y (grammar_declaration): Likewise.
9652 Use muscle_code_grow, so that we don't need stype_line any more.
9653 All uses changed.
9654
9655 * src/muscle_tab.c (muscle_grow): Fix comment.
9656
9657 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
9658 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
9659 Update copyright year to 2006.
9660
9661 2006-01-03 Akim Demaille <akim@epita.fr>
9662
9663 Have glr.cc pass (some of) the calc.at tests.
9664 * data/glr.cc (b4_parse_param_orig): New.
9665 (b4_parse_param): Improve its definition, and bound it more
9666 clearly in the skeleton.
9667 (b4_epilogue): Append, instead of prepending, in order to keep
9668 #line consistency.
9669 Simplify the generation of auxiliary functions: locations and
9670 purity are mandated.
9671 (b4_global_tokens_and_yystype): Honor it.
9672 * data/location.cc (c++.m4): Don't include it.
9673 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
9674 and AT_SKEL_CC_IF.
9675 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
9676 AT_LALR1_CC_IF.
9677 Be sure to initialize the first position's filename.
9678 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
9679 mandated anyway.
9680 (AT_CHECK_CALC_GLR_CC): New.
9681 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
9682
9683 2006-01-02 Akim Demaille <akim@epita.fr>
9684
9685 * src/output.c (output_skeleton): Don't hard wire the inclusion of
9686 c.m4.
9687 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.
9688 * data/glr.cc: Do not include stack.hh.
9689
9690 2006-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
9691
9692 * data/glr.c: Reformat whitespace with tabs.
9693 (b4_lpure_formals): Remove this unused m4 macro.
9694 * tests/cxx-type.at: Reformat whitespace with tabs.
9695 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
9696 since it's a member. Rename type to isNterm for clarity.
9697
9698 2005-12-29 Akim <akim@sulaco.local>
9699
9700 Let glr.cc catch up with symbol_value_print.
9701 * data/glr.cc (b4_yysymprint_generate): Replace by...
9702 (b4_yy_symbol_print_generate): this.
9703 (yy_symbol_print, yy_symbol_value_print): Declare them.
9704
9705 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
9706
9707 * src/location.h (boundary): Note that a line or column equal
9708 to INT_MAX indicates an overflow.
9709 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
9710 (rule_length_overflow, increment_rule_length, add_column_width):
9711 New functions.
9712 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
9713 (<SC_BRACED_CODE>"}"):
9714 Use increment_rule_length rather than incrementing it by hand.
9715 (adjust_location, handle_syncline): Diagnose overflow.
9716 (handle_action_dollar, handle_action_at):
9717 Fix bug with monstrosities like $-2147483648.
9718 Remove now-unnecessary checks.
9719 (scan_integer): Verify assumptions and remove now-unnecessary checks.
9720 (convert_ucn_to_byte): Verify assumptions.
9721 (handle_syncline): New arg LOC. All callers changed.
9722 Don't store through a value derived from char const * pointer.
9723

9725 GCC warnings.
9726
9727 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
9728
9729 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
9730 Remove unnecessary forward static decls.
9731
9732 2005-12-27 Akim Demaille <akim@epita.fr>
9733
9734 * src/reader.c (grammar_current_rule_check): Also check that $$
9735 is used.
9736 Take the rule to check as argument, hence rename as...
9737 (grammar_rule_check): this.
9738 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
9739 Rename as...
9740 (grammar_rule_begin, grammar_rule_end): these, for consistency.
9741 (grammar_midrule_action, grammar_symbol_append): Now static.
9742 * tests/torture.at (input): Don't rely on the default action
9743 being always performed.
9744 * tests/calc.at: "Set" $$ even when the action is "cut" with
9745 YYERROR or other.
9746 * tests/actions.at (Exotic Dollars): Instead of using unused
9747 values, check that the warning is issued.
9748
9749 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
9750
9751 * NEWS: Improve wording for unused-value warnings.

9755 * data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4
9756 (b4_yysymprint_generate): Rename as...
9757 (b4_yy_symbol_print_generate): this.
9758 Generate yy_symbol_print instead of yysymprint.

9772 * tests/existing.at: Remove the type information.
9773 Empty the actions.
9774 Remove useless actions (beware of mid-rule actions: perl -000
9775 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
9776 * tests/actions.at (Exotic Dollars): Use unused values.
9777 * tests/calc.at: Likewise.
9778 * tests/glr-regression.at (No users destructors if stack 0 deleted):
9779 Likewise.
9780
9781 * src/gram.c (rule_useful_p, rule_never_reduced_p): Use
9782 rule_useful_p.
9783
9784 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
9785
9786 Undo 2005-12-01 tentative license wording change. The wording is
9787 still being reviewed by the lawyers, and we don't want to wait for
9788 them before publishing a test release. For now, revert to the
9789 previous wording.
9790 * NEWS: Undo 2005-12-01 change.
9791 * data/glr.c: Revert to previous license wording.
9792 * data/glr.cc: Likewise.
9793 * data/lalr1.cc: Likewise.
9794 * data/location.cc: Likewise.
9795 * data/yacc.c: Likewise.
9796
9797 * NEWS: Reword %destructor vs YYABORT etc.
9798 * data/glr.c: Use American spacing, for consistency.
9799 * data/glr.cc: Likewise.
9800 * data/lalr1.cc: Likewise.
9801 * data/yacc.c: Likewise.
9802 * data/yacc.c: Reformat comments slightly.
9803 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
9804 for consistency. Fix some spelling errors and reword recently-included
9805 text slightly.
9806 * tests/cxx-type.at: Cast results of malloc, for C++.
9807
9808 2005-12-21 Joel E. Denny <address@hidden>
9809
9810 * tests/cxx-type.at: Construct a tree, count the parents of shared
9811 nodes, and free each node once and only once. Previously, the memory
9812 for semantic values was leaked instead.
9813
9814 2005-12-21 Joel E. Denny <address@hidden>
9815
9816 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
9817 (yylval, yylloc): If pure, #define to yystackp->yyval and
9818 yystackp->yyloc similar to yychar and yynerrs.
9819 (yyparse): If pure, remove local yylval and yylloc. Add local
9820 yystackp to accommodate pure definitions of yylval and yylloc.
9821 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
9822 yylvalp and yyllocp to &yylval and &yylloc.
9823 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
9824 namespace. Previously, nerrs and char were missing, but lval and lloc
9825 weren't necessary.
9826 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
9827 yylvalp and yyllocp parameters since, if pure, these are now always

9834
9835 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
9836 destroy the RHS symbols of a rule.
9837 * data/yacc.c (yylen): Initialize to 0.
9838 Keep its value to the number of items to possibly shift.
9839 In particular, a regular successful parse that ends on YYFINAL by
9840 a (internal) YYACCEPT must not have yylen != 0.
9841 (yyerrorlab, yyreturn): Pop the RHS.
9842 Reorder a bit to emphasize the `shifting' bits of code.
9843 (YYPOPSTACK): Now accept a number of items to pop.

9856 * djgpp/config.sed: Replace every occurence of the file name
9857 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with

9872
9873 * data/glr.c: Reorder typedef declarations for structs to match order

9885
9886 * tests/sets.at (Accept): Fix typos in regular expression used to
9887 sed out the final state number.
9888
9889 Work around portability problem on Solaris 10: flex-generated
9890 files include <stdio.h> before <config.h>, which messes up
9891 because the latter defines __EXTENSIONS__. Address the problem
9892 by creating two new little files that include <config.h> first,
9893 then include the flex-generated files. Rewrite everyone else
9894 to include <config.h> first, as well.
9895 * lib/timevar.c: Always include "config.h".
9896 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

9932
9933 Cleanups so that Bison-generated parsers have less lint.
9934 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
9935 Prepend /*ARGSUSED*/, for lint's sake.
9936 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
9937 definition if 'lint' is defined.
9938 (YYID): New macro (or function, if lint).
9939 All uses of /*CONSTCOND*/0 replaced by YYID(0).
9940 * data/yacc.c: Likewise.
9941 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
9942 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
9943 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
9944 is C++ only.
9945 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.

9963 New test case.
9964 (Duplicated user destructor for lookahead): This test now is expected
9965 to succeed.
9966
9967 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
9968
9969 * NEWS: Document the following change.
9970 * data/yacc.c: Say "parser skeleton" rather than "file", since
9971 it's no longer just a file.
9972 * data/glr.c: Grant a special exception for C GLR parsers, that
9973 reads like the already-existing exception for C LALR(1) parsers.
9974 * data/glr.cc: Likewise.
9975 * data/lalr1.cc: Likewise.
9976 * data/location.cc: Likewise.
9977 * data/yacc.c: Reword the "written by" statement to clarify that
9978 it was the parser skeleton, not the entire output file.

9984
9985 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
9986 Fix typos in previous change that broke 'make check'.
9987 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
9988 supported in C.
9989 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
9990 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
9991 We can revert this once things settle down.
9992
9993 * src/conflicts.c (conflicts_print): Don't print file name twice
9994 when %expect fails because there were no conflicts.
9995 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
9996 change.
9997 * tests/conflicts.at (%expect not enough, %expect too much):
9998 (%expect with reduce conflicts): Adjust to new behavior.

10025 from 1 to N, while values and location start at 0.
10026 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
10027

10130
10131 * bootstrap (cleanup_gnulib): New function. Use it to clean up
10132 gnulib when interrupted. This fixes some race conditions and

10136 2005-10-22 Akim <akim@epita.fr>
10137

10179
10180 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at

10184 already defined it.

10248 * src/gram.c (grammar_dump): Likewise.
10249 * src/lalr.c (look_ahead_tokens_print): Likewise.
10250 * src/output.c (escaped_output): Likewise.
10251 (user_actions_output): Break apart two printfs.
10252 * src/parse-gram.y (%printer): Prefer printf to putc and puts.
10253 * src/reduce.c (reduce_print): Likewise.
10254 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
10255 * src/system.h: Include unlocked-io.h rathe than stdio.h.
10256
10257 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
10258 Use assignments rather than casts-to-void to suppress
10259 unused-variable warnings. This pacifies 'lint'.

10261 unused-variable warnings.
10262
10263 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

10265 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
10266
10267 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
10268
10269 Use unlocked I/O for a minor performance improvement on hosts like
10270 GNU/Linux and Solaris that support unlocked I/O. The basic idea
10271 is to use the gnlib unlocked-io module, and to prefer putc and
10272 puts to printf when either will work (since the latter doesn't
10273 come in an unlocked flavor).
10274 * bootstrap (gnulib_modules): Add unlocked-io.
10275 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
10276 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

10278 and similarly for puts and putc and printf.
10279 * data/yacc.c: Likewise.
10280 * lib/bitset.c (bitset_print): Likewise.
10281 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
10282 * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
10283 to printf.
10284 * lib/lbitset.c (debug_lbitset): Likewise.
10285 * src/closure.c (print_firsts, print_fderives): Likewise.
10286 * src/gram.c (grammar_dump): Likewise.
10287 * src/lalr.c (look_ahead_tokens_print): Likewise.
10288 * src/output.c (escaped_output): Likewise.
10289 (user_actions_output): Coalesce two printfs.
10290 * src/parse-gram.y (%printer): Prefer putc and puts to printf.
10291 * src/reduce.c (reduce_print): Likewise.
10292 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
10293 * src/system.h: Include unlocked-io.h rather than stdio.h.
10294
10295 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
10296 this confuses xgettext.
10297

10337
10338 2005-10-02 Juan Manuel Guerrero <juan.guerrero@gmx.de>
10339
10340 * lib/subpipe.c: New function end_of_output_subpipe() added
10341 to allow support for non-posix systems. This is a no-op function
10342 for posix systems.
10343
10344 * lib/subpipe.h: New function end_of_output_subpipe() added
10345 to allow support for non-posix systems. This is a no-op function
10346 for posix systems.
10347
10348 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
10349 handle the lack of pipe/fork functionality on non-posix systems.
10350
10351 * djgpp/Makefile.maint: DJGPP specific file.

10367 2005-10-02 Akim Demaille <akim@epita.fr>
10368
10369 * data/location.cc: New, extract from...
10370 * data/lalr1.cc: here.
10371 (location.hh): Include it after the user prologue, in case the
10372 filename type is defined by the user.
10373 Forward declation location and position before the pre-prologue.
10374 (yyresult_): Rename as...
10375 (yyresult): this, it's a local variable, not an attribute.
10376 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
10377
10378 2005-10-01 Akim Demaille <akim@epita.fr>
10379

10381
10382 2005-09-30 Akim Demaille <akim@epita.fr>,
10383 Alexandre Duret-Lutz <adl@gnu.org>
10384
10385 Move the token type and YYSTYPE in the parser class.
10386 * data/lalr1.cc (stack.hh, location.hh): Include earlier.
10387 (parser::token): New, from the moved free definition of tokens.
10388 (parser::semantic_value): Now a full definition instead of an
10389 indirection to YYSTYPE.
10390 (b4_post_prologue): No longer included in the header file, but
10391 in the implementation file.
10392 * doc/bison.texi (C+ Language Interface): Update.
10393 * src/parse-gram.y: Support unary %define.

10400 2005-09-29 Paul Eggert <eggert@cs.ucla.edu>
10401
10402 Port to SunOS 4.1.4, which lacks strtoul and strerror.
10403 Ah, the good old days! Problem reported by Peter Klein.
10404 * bootstrap (gnulib_modules): Add strerror, strtoul.
10405 * lib/.cvsignore: Add strerror.c, strtol.c, strtoul.c
10406 * m4/.cvsignore: Add strerror.m4, strtol.m4, strtoul.m4.

10414 parser members, replaced by...
10415 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
10416 local variables.
10417 (yysyntax_error_): Takes the state number as argument.
10418 (yyreduce_print_): Use the argument yyrule, not the former
10419 attribute yyn_.
10420
10421 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
10422
10423 * bootstrap (gnulib_modules): Add verify.

10426 * src/system.h (verify): Remove.
10427 Include verify.h instead.
10428 * src/tables.c (tables_generate): Use new API for 'verify'.
10429
10430 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
10431
10432 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
10433 local variables whose names begin with 'yy'.

10435 Trivial changes from Joel E. Denny.
10436
10437 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
10438 it itself.
10439 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
10440 don't use alloca any more.
10441
10442 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
10443 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
10444 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
10445 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
10446 to match yacc.c, to test more hosts.
10447
10448 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
10449
10450 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
10451 doesn't affect behavior.
10452 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
10453 Solaris, AIX, MSC.
10454 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
10455 This works a bit better with glibc, if user code has already included
10456 stdlib.h.
10457 * doc/bison.texinfo (Bison Parser): Document that users can't
10458 arbitrarily use malloc and free for other purposes. Document
10459 that <alloca.h> and <malloc.h> might be included.
10460 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
10461 user must declare alloca.

10463 * HACKING (release): Forwarn the Translation Project about
10464 stable releses.
10465
10466 2005-09-20 Akim Demaille <akim@epita.fr>

10471
10472 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
10473 (YYSTACK_ALLOC_MAXIMUM): Use it.
10474 (yysyntax_error): New function.
10475 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
10476 multiple syntax errors are reported, and alloca is being used.
10477 Instead, reallocate buffers twice as big each time, so that
10478 we waste at most half the allocated memory. Start with a small
10479 (128-byte) buffer that will suffice in most cases anyway.
10480 Use yysyntax_error to do most of the work.
10481
10482 * doc/bison.texinfo (Error Reporting, Table of Symbols):
10483 yynerrs is the number of errors reported, not the number of
10484 errors encountered.
10485
10486 * tests/glr-regression.at (Duplicated user destructor for lookahead):
10487 Mark it as expected to fail.
10488 Cast result of malloc; problem reported by twlevo@xs4all.nl.
10489 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
10490 Don't start user-code symbols with "yy", to avoid name space problems.
10491
10492 2005-09-19 Akim Demaille <akim@epita.fr>
10493
10494 Remove the traits, failed experiment.
10495 It never proved useful, and anyway because of the current
10496 definition, it was not possible to have several specialization of
10497 this traits, making it useless.
10498 * data/lalr1.cc (yy:traits): Remove.
10499 Inline its definitions in the parser class.
10500
10501 2005-09-19 Akim Demaille <akim@epita.fr>

10507
10508 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
10509 and yytoken for similarity with the other skeletons.

10520 official release.
10521 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
10522 diagnostic.
10523 * src/output.c (prepare): Likewise.
10524 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
10525 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
10526 is not defined. This is an awful hack, but it's enough for now.
10527 All callers changed.
10528 * tests/glr-regression-at (make_value): Args are const pointers now,
10529 to avoid GCC warning.
10530 (Duplicated user destructor for lookahead): New test. Currently
10531 skipped. It fails on my host but I'm not sure it'll always fail.
10532
10533 2005-09-16 Akim Demaille <akim@epita.fr>
10534
10535 * src/symtab.h (struct symbol): Declare the printer and destructor
10536 as const, to avoid accidental calls to free.
10537 (symbol_destructor_set, symbol_printer_set): Adjust.
10538 * src/symtab.c: Adjust.
10539
10540 2005-09-16 Akim Demaille <akim@epita.fr>
10541
10542 * data/c.m4 (b4_token_enums): New.
10543 (b4_token_defines): Rename as...
10544 (b4_token_enums_defines): this.
10545 (b4_token_defines): New, output only the #defines.
10546 * data/yacc.c, data/glr.c: Adjust.
10547 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
10548 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
10549 as default values.
10550
10551 2005-09-16 Akim Demaille <akim@epita.fr>
10552
10553 * data/lalr1.cc (yylex_): Remove, inline its code.
10554 (yyreport_syntax_error_): Remove, replaced by...
10555 (yysyntax_error_): this which returns a string and leaves to the
10556 caller the call to the users' error function.
10557 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
10558 Move from members of the parser object...
10559 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
10560 to local variables of the parse function.
10561
10562 2005-09-16 Akim Demaille <akim@epita.fr>
10563
10564 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF

10568
10569 * data/glr.c (yyresolveValue): Add default case to pacify
10570 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.

10573 * doc/bison.texinfo (Parser Function): Document when yyparse
10574 returns 2.
10575
10576 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
10577 (b4_filename_type): Renamed back from b4_file_name_type. All uses
10578 changed.
10579 (class position): file_name -> filename (reverting). All uses changed.
10580
10581 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
10582
10583 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't

10585 patch.
10586
10587 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
10588
10589 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
10590 contains obsolete information and isn't worth distributing as a
10591 separate file anyway.
10592 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
10593 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
10594 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
10595 (yyparse): Abort if user code uses longjmp to throw an unexpected
10596 value.
10597
10598 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
10599

10601 Suggested by twlevo@xs4all.nl.
10602
10603 * data/glr.c (YYCHK1): Do not assume YYE is in range.
10604 This avoids a diagnostic from gcc -Wswitch-enum.
10605 Problem reported by twlevo@xs4all.nl.
10606
10607 * doc/bison.texinfo: Don't use "filename", as per GNU coding
10608 standards. Use "file name" or "file" or "name", depending on
10609 the context.
10610 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
10611 not to hack/foo.tab.c.

10622 * src/files.c (file_name_split): Renamed from filename_split.
10623 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
10624
10625 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
10626
10627 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
10628 to accommodate latest gnulib.
10629
10630 * tests/glr-regression.at (Duplicate representation of merged trees):
10631 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
10632
10633 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
10634 needed.
10635
10636 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
10637
10638 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.

10644 Problem reported by Joel E. Denny in:
10645 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
10646
10647 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
10648
10649 * README-cvs: Give URLs for recommended tools.
10650 Mention Gzip version problem, and bootstrapping issues.
10651 Remove troubleshooting section, as it's somewhat obsolete.
10652
10653 * bootstrap (no_cache): New var, to accommodate different wget
10654 variants. Use it instead of '-C off'. Problem reported by
10655 twlevo@xs4all.nl.
10656
10657 * data/glr.c (yydestroyStackItem): New function.
10658 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
10659 debugging information. Problem reported by Joel E. Denny.
10660
10661 2005-08-25 Akim Demaille <akim@epita.fr>
10662
10663 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
10664
10665 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
10666
10667 * data/glr.c (yyrecoverSyntaxError, yyreturn):
10668 Don't invoke destructor on unresolved entries.
10669 * tests/glr-regression.at
10670 (User destructor for unresolved GLR semantic value): New test case.
10671 Problem reported by Joel E. Denny in:
10672 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
10673
10674 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
10675
10676 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
10677 Add strnlen.c.
10678 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
10679 lib-prefix.m4, po.m4.
10680
10681 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
10682 in yydestruct diagnostic, since it might not be an error.
10683 Problem reported by Joel Denny near end of
10684 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
10685 * data/lalr1.cc (yyerturn): Likewise.
10686 * data/yacc.c (yyreturn): Likewise.
10687 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
10688
10689 * src/files.c: Remove obsolete FIXME comment.
10690
10691 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
10692 with the other templates, and to fix bogus run-on messages such
10693 as the one reported at the end of
10694 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
10695 All callers changed to avoid the newline.
10696 (yyprocessOneStack): Output two lines rather than one, to accommodate
10697 the above change. This changes the debug output format slightly.
10698
10699 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
10700 reported by Joel E. Denny in
10701 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
10702 (trivial change).
10703 * tests/glr-regression.at (Duplicate representation of merged trees):
10704 New test, from Joel E. Denny in:
10705 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
10706 * THANKS: Add Joel E. Denny.
10707
10708 * configure.ac (AC_INIT): Bump to 2.0c.
10709
10710 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
10711
10712 * NEWS: Version 2.0b.
10713
10714 * Makefile.am (SUBDIRS): Put examples before tests, so that
10715 "make check" doesn't finish with "All 1 tests passed".
10716
10717 * tests/regression.at (Token definitions): Don't rely on
10718 AT_PARSER_CHECK for data that contains backslashes. It currently
10719 uses 'echo', and 'echo' isn't portable if its argument contains
10720 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
10721 that the byte '\0xff' is not printable in the C locale; it is,
10722 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
10723 not printable, so use '\0x81' to test.
10724
10725 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
10726 version of GCC, since the macro is used with non-GCC compilers.
10727
10728 Fix core dump reported by Pablo De Napoli in
10729 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
10730 * tests/regression.at (Invalid inputs with {}): New test.
10731 * src/parse-gram.y (token_name): Translate type before using
10732 it as an index.
10733
10734 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
10735 the user's name space. All uses changed to __attribute__
10736 ((__unused__)).
10737 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
10738 Add __attribute__ ((__noreturn__)).
10739
10740 * etc/clcommit: Remove. We weren't using it, and it failed
10741 "make maintainer-distcheck".
10742 * Makefile.maint: Merge from coreutils.
10743 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
10744 (syntax-check-rules): Change list of rules as described below.
10745 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
10746 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
10747 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
10748 (sc_trailing_space): New rules.
10749 (sc_xalloc_h_in_src): Remove.
10750 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
10751 (sc_space_tab, sc_error_exit_success, sc_changelog):
10752 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
10753 (makefile-check, po-check, author_mark_check):
10754 (makefile_path_separator_check, copyright-check):
10755 Use grep -n, to make it easier to find violations.
10756 Use CVS_LIST and CVS_LIST_EXCEPT.
10757 (header_regexp, h_re): Remove.
10758 (dd_c): New macro.
10759 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
10760 (my-distcheck): Use more-modern GCC flags.
10761 (signatures, %.asc): Remove.
10762 (rel-files, announcement): Remove signatures.
10763 Restore old updating code, even though we don't use it, so
10764 that we're the same as coreutils.
10765 (alpha, beta, major): Depend on news-date-check.
10766 Make the upload commands.
10767
10768 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
10769 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
10770 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
10771 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
10772 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
10773 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
10774 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
10775 * tests/sets.at: Likewise.
10776
10777 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
10778 we comment out the Autoconf version number.
10779 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
10780 it's error-prone and "make maintainer-distcheck" rejects it.
10781
10782 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
10783 Indent calls to "error" to pacify "make maintainer-distcheck",
10784 when the calls are not intended to be translated.
10785 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
10786
10787 * src/Makefile.am (DEFS): Use +=, to pacify
10788 "make maintainer-distcheck".
10789 (bison_SOURCES): Add scan-skel.h.
10790 (sc_tight_scope): New rule, from coreutils.
10791
10792 * src/files.c (src_extension, header_extension):
10793 Now static, not extern.
10794 * src/getargs.c (short_options): Likewise.
10795 * src/muscle_tab.c (muscle_table): Likewise.
10796 * src/parse-gram.y (current_class, current_type, current_prec):
10797 Likewise.
10798 * src/reader.c (grammar_end, previous_rule_end): Likewise.
10799 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
10800 * src/main.c (main): Cast bindtextdomain and textdomain calls to
10801 void, to avoid warning when NLS is disabled.
10802 * src/output.c: Include scan-skel.h.
10803 (scan_skel): Remove decl, since scan-skel.h does this.
10804 (output_skeleton):
10805 Indent calls to "error" to pacify "make maintainer-distcheck".
10806 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
10807 * src/reader.h (gram_end, gram_lineno): New decls to pacify
10808 "make maintainer-distcheck".
10809 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
10810 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
10811 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
10812 (skel_lex_destroy, scan_skel): Move these decls to...
10813 * src/scan-skel.h: New file.
10814 * src/uniqstr.c (uniqstr_assert):
10815 Indent calls to "error" to pacify "make maintainer-distcheck".
10816
10817 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
10818 not @VAR@.
10819
10820 * tests/torture.at: Revamp to avoid misuse of atoi that
10821 "make maintainer-distcheck" complained about.
10822
10823 * examples/extexi (message): Don't print a message more than once,
10824 and omit line-number decoration that makes Emacs compile think
10825 that informative messages are worth worrying about.
10826
10827 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
10828
10829 * configure.ac: Update version number.
10830
10831 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
10832 accidentally.
10833 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
10834 autogenerated by the maintainer.
10835 * examples/calc++/.cvsignore: Add *.yy.
10836
10837 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
10838 * lib/bitset_stats.c (bitset_stats_init): Likewise.
10839 * lib/bitsetv.c (bitsetv_alloc): Likewise.
10840
10841 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
10842
10843 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
10844 from maintainer-distcheck about casting the argument of 'free'.
10845
10846 * NEWS: Mention recent yytname changes.
10847 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
10848
10849 * bootstrap: For translations that have not yet been upgraded to
10850 the new runtime-po domain, prime the pump by extracting the
10851 relevant strings from the obsolete translations. This code can be
10852 removed once the bison-runtime domain has been translated by each
10853 team.
10854
10855 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
10856 now that token names are already quoted.
10857
10858 Fix problem reported by Anthony Heading.
10859 * data/glr.c (YYTOKEN_TABLE): New macro.
10860 (yytname): Define if YYTOKEN_TABLE.
10861 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
10862 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
10863 (YYERROR_VERBOSE): Define the same way the other skeletons do.
10864 * src/output.c (prepare_symbols): Output token_table_flag.
10865
10866 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
10867
10868 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
10869 again if the first call fails.
10870
10871 * data/glr.c (yytnamerr): New function.
10872 (yyreportSyntaxError): Use it to dequote most string literals.
10873 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
10874 with other skeletons. All uses changed.
10875 (yytnameerr_): New function.
10876 (yyreport_syntax_error): Use it to dequote most string literals.
10877 * data/yacc.c (yytnamerr): New function.
10878 (yyerrlab): Use it to decode most string literals.
10879 * doc/bison.texinfo (Decl Summary, Calling Convention):
10880 Clarify quoting convention of yytname.
10881 * src/output.c (prepare_symbols): Quote all names. This undoes
10882 the 2005-04-17 change, which is now accomplished (mostly) via
10883 changes in the parsers as described above.
10884 * tests/regression.at (Token definitions, Web2c Actions):
10885 Undo most 2005-04-17 change here, too.
10886
10887 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
10888
10889 Fix more problems reported by twlevo@xs4all.nl.
10890 * tests/cxx-type.at: Don't pipe output of ./types through sed to
10891 remove trailing spaces. This loses the exit status of ./types,
10892 and isn't needed since ./types shouldn't be emitting trailing
10893 spaces.
10894 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
10895 as the stack isn't valid in that case.
10896
10897 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
10898 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
10899 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
10900 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
10901 is used.
10902 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
10903 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
10904 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
10905 Likewise.
10906
10907 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
10908 overly-picky compilers that reject 'char *foo = "bar";'.
10909
10910 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
10911 to FILE * parameter, not to stderr. This fixes a typo introduced
10912 in the 2005-07-12 change.
10913
10914 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
10915 warnings from GCC 4.
10916
10917 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
10918 (yyglrShiftDefer, yysplitStack):
10919 Remove unused parameters b4_pure_formals. All uses changed.
10920 (yyglrShift): Remove unused parameters b4_user_formals.
10921 All uses changed.
10922 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
10923
10924 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
10925
10926 Destructor cleanups and regularization among the three skeletons.
10927 * NEWS: Document the behavior changes.
10928 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
10929 stack before failing, as the cleanup code will do it for us now.
10930 * data/lalr1.cc (yyerrlab): Likewise.
10931 * data/glr.c (yyparse): Pop everything off the stack before
10932 freeing it, so that destructors get called properly.
10933 * data/lalr1.cc (yyreturn): Likewise.
10934 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
10935 This is more consistent.
10936 * doc/bison.texinfo (Destructor Decl): Mention more reasons
10937 why destructors might be called. 1.875 -> 2.1.
10938 (Destructor Decl, Decl Summary, Table of Symbols):
10939 Some English-language cleanups for %destructor.
10940 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
10941 Add output line for destructor of start symbol.
10942 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
10943 because of that same extra output line.
10944
10945 * NEWS: Document minor wording changes in diagnostics of
10946 Bison-generated parsers.
10947 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
10948 Remove unused formals. All uses changed.
10949 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
10950 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
10951 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
10952 Rename yyoverflowab to yyexhaustedlab.
10953 When memory exhaustion occurs during syntax-error reporting,
10954 report it separately rather than in a single diagnostic; this
10955 eases translation.
10956 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
10957 (Memory Exhausted): Renamed from Parser Stack Overflow.
10958 Revamp wording slightly to prefer "memory exhaustion".
10959 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
10960
10961 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
10962
10963 Add i18n support to the GLR skeleton. Partially fix the C++
10964 skeleton; a C++ expert needs to finish this. Remove debugging
10965 msgids; there's little point to having them translated, since they
10966 can be understood only by someone who can read the
10967 (English-language) source code.
10968
10969 Generate runtime-po/bison-runtime.pot automatically, so that we
10970 don't have to worry about garbage getting in that file. We'll
10971 make sure after the next official release that old msgids don't
10972 get lost. See
10973 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
10974
10975 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
10976 Now auto-generated.
10977 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
10978 Fix typos in explanations of the runtime file.
10979 * bootstrap: Change gettext keyword from YYI18N to YY_.
10980 Use standard Makefile.in.in in runtime-po, since we'll arrange
10981 for backward-compatible bison-runtime.po files in a different way.
10982 * data/glr.c (YY_): New macro, from yacc.c.
10983 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
10984 Translate messages intended for users.
10985 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
10986 the wording in the other skeletons. We don't know that the memory
10987 is virtual.
10988 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
10989 Use same method that yacc.c uses.
10990 Don't translate debugging messages.
10991 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10992 it doesn't work (yet), and requires C++ expertise to fix.
10993 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10994 Move defn to a more logical place, to be consistent with other
10995 skeletons.
10996 Don't translate debugging messages.
10997 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10998 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10999 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
11000 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
11001
11002 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
11003 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
11004 void, not int.
11005 * tests/glr-regression.at (Badly Collapsed GLR States):
11006 Likewise.
11007 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
11008 yylex should return 0 at EOF rather than aborting.
11009
11010 Improve tests for stack overflow in GLR parser.
11011 Problem reported by twlevo@xs4all.nl.
11012 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
11013 All uses removed.
11014 (yyStackOverflow): Just longjmp, but with value 2 so that caller
11015 can handle the problem.
11016 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
11017 (yyparse): New local variable yyresult to record the result.
11018 Use result of setjmp to set it, rather than storing itinto
11019 struct.
11020 (yyDone): Remove label.
11021 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
11022 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
11023 if YYABORT is used).
11024 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
11025 yyparse status; put status > 1 into diagnostic.
11026 Check that status==2 works.
11027 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
11028 Use exit status 3 for failure to open (which shouldn't happen).
11029
11030 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
11031
11032 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
11033 1 on syntax error; just let yyparse do its thing.
11034 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
11035 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
11036 (Exploding the Stack Size with Alloca):
11037 (Exploding the Stack Size with Malloc):
11038 Expect exit status 2, not 1, since the parser is supposed to blow
11039 its stack. Problem reported by twlevo@xs4all.nl.
11040
11041 * data/glr.c (yyparse): Don't assume that the initial calls
11042 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
11043 Print a stack-overflow message and fail instead.
11044 Initialize the line-number information before creating the stack,
11045 so that the stack-overflow message can report line zero safely.
11046
11047 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
11048
11049 Fix problems reported by twlevo@xs4all.nl.
11050 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
11051 (yyuserMerge): Provide a default case if b4_mergers is empty.
11052 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
11053 * tests/glr-regression.at
11054 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
11055 Add casts to pacify C++ compilers.
11056 * tests/glr-regression.at (Improper merging of GLR delayed action
11057 sets): Declare yylex before using it.
11058 * tests/Makefile.am (maintainer-check-g++): Fix a stray
11059 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
11060 test for valgrind; valgrind is independent of g++.
11061 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
11062 for compatibility with POSIX 1003.1-2001 (if running coreutils).
11063 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
11064 Use a destructor, so that we can expand the stack. Change
11065 YYSTYPE to char * so that we can free it. Cast result of malloc.
11066
11067 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11068
11069 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
11070 a valgrind failure. Problem reported by twlevo@xs4all.nl.
11071
11072 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
11073
11074 * PACKAGING: New file, suggested by Bruno Haible and taken from
11075 similar wording in gettext's PACKAGING file.
11076 * NEWS: Mention PACKAGING.
11077 * Makefile.am (EXTRA_DIST): Add PACKAGING.
11078
11079 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
11080
11081 * NEWS: Document recent i18n improvements.
11082 * bootstrap: Get runtime translations into runtime-po.
11083 Create runtime-po files automatically, if possible.
11084 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
11085 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
11086 does not infringe on the user's name space.
11087 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
11088 * doc/bison.texinfo (Internationalization): Revamp the English
11089 and Texinfo syntax a bit, to try to make it clearer.
11090 (Bison Options, Option Cross Key): Mention --print-localedir.
11091 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
11092 YYENABLE_NLS. Quote a bit more.
11093 * runtime-po/.cvsignore: New file.
11094 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
11095 * runtime-po/Rules-quot: Remove; now created by bootstrap.

11097 * runtime-po/boldquot.sed: Likewise.
11098 * runtime-po/en@quot.header: Likewise.
11099 * runtime-po/en@boldquot.header: Likewise.
11100 * runtime-po/insert-header.sin: Likewise.
11101 * runtime-po/remove-potcdate.sin: Likewise.
11102 * runtime-po/Makevars: Likewise.
11103 * runtime-po/LINGUAS: Likewise.
11104 * runtime-po/de.po: Likewise; we will rely on the translation project
11105 to maintain this, so "bootstrap" should get it.
11106 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
11107 its value.
11108 * src/main.c (main): Bind the bison-runtime domain, too.
11109
11110 2005-07-12 Bruno Haible <bruno@clisp.org>
11111
11112 * data/yacc.c: Include <libintl.h> when NLS is enabled.
11113 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
11114 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
11115 * runtime-po: New directory.
11116 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
11117 $(DOMAIN).pot-update rule, so that old messages are never dropped.
11118 * runtime-po/Rules-quot: New file, copied from po/.
11119 * runtime-po/quot.sed: Likewise.
11120 * runtime-po/boldquot.sed: Likewise.

11122 * runtime-po/en@boldquot.header: Likewise.
11123 * runtime-po/insert-header.sin: Likewise.
11124 * runtime-po/remove-potcdate.sin: Likewise.

11128 * runtime-po/bison-runtime.pot: New file.
11129 * runtime-po/de.po: New file.
11130 * m4/bison.m4: New file.
11131 * Makefile.am (SUBDIRS): Add runtime-po.
11132 (aclocaldir, aclocal_DATA): New variables.
11133 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
11134 Define aclocaldir.
11135 * src/getargs.c (usage): Document --print-localedir option.
11136 (PRINT_LOCALEDIR_OPTION): New enum item.
11137 (long_options): Add --print-localedir option.
11138 (getargs): Handle --print-localedir option.

11141
11142 2005-07-12 Akim Demaille <akim@epita.fr>
11143
11144 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
11145 for consistency with the rest of the code.
11146 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
11147 Add separators.
11148
11149 2005-07-12 Akim Demaille <akim@epita.fr>
11150
11151 * src/parse-gram.y: Use %printer instead of YYPRINT.
11152
11153 2005-07-12 Akim Demaille <akim@epita.fr>
11154
11155 * src/symtab.h, src/symtab.c (symbol_print): New.
11156 * src/symlist.h, src/symlist.c (symbol_list_print): New.
11157 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
11158
11159 2005-07-12 Akim Demaille <akim@epita.fr>
11160
11161 * data/glr.c (b4_syncline): Fix (swap) the definitions of
11162 b4_at_dollar and b4_dollar_dollar.
11163
11164 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
11165
11166 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
11167 and Pennello's paper.
11168
11169 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
11170
11171 * data/yacc.c (yyparse): Undo previous patch. Instead,
11172 set yylsp[0] and yyvsp[0] only if the initial action
11173 sets yylloc and yylval, respectively.
11174
11175 * data/yacc.c (yyparse): In the initial action, set
11176 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
11177 This avoids the use of undefined variables if the initial
11178 action does not set yylloc and/or yylval.
11179
11180 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
11181
11182 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
11183 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
11184 Remove from CVS. These files are automatically generated.
11185 * examples/extexi: Clarify that this file is now part of Bison,
11186 not GNU M4, and that it works with any POSIX-compatible Awk.
11187 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
11188 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
11189 so that we also get calc++-parser.yy. Geneate it.
11190 Use $(AWK), not gawk, since any conforming Awk will do.
11191 Put comment before action, since older 'make' can't handle comment
11192 in action.
11193 $(BUILT_SOURCES): List all built sources, not just some of them.
11194 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
11195 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
11196 $($(calc_sources_generated)): Remove unnecessary test for existence
11197 of target. (This had a shell syntax error anyway; a stray "x".)
11198 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
11199 calc++-parser.yy.
11200 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
11201
11202 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
11203 implied by the other modules.
11204
11205 2005-07-06 Akim Demaille <akim@epita.fr>
11206
11207 Bind examples/calc++ to the package.
11208 * examples/calc++/Makefile: Remove, replaced by...
11209 * examples/calc++/Makefile.am: ... this new file.
11210 * examples/calc++/test: Remove input.
11211 * examples/calc++/compile: Remove.
11212 * examples/Makefile.am: New.
11213 * configure.ac, Makefile.am: Adjust.
11214 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
11215
11216 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
11217
11218 * data/glr.c (yyFail): Drastically simplify; since the format argument
11219 never had any % directives, we can simply pass it to yyerror.
11220 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
11221 be modified later, as that is the usual style in glr.c.
11222 Problems reported by Paul Hilfinger.
11223
11224 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
11225 and size overflow errors.
11226 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
11227 in case the user prolog sets feature-test macros like _GNU_SOURCE.
11228 (YYSIZEMAX): New macro.
11229 (yystpcpy): New function, taken from yacc.c.
11230 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
11231 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
11232 so that we don't have to maintain their signatures.
11233 (yyFail): Check for buffer overflow, by using vsnprintf rather
11234 than vsprintf. Allocate a bigger buffer if possible.
11235 Report an error if buffer allocation fails.
11236 (yyStackOverflow): New function.
11237 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
11238 the initialization was successful. It might fail if storage was
11239 exhausted.
11240 (yyexpandGLRStack): Add more checks for storage allocation failure.
11241 Use yyStackOverflow to report failures.
11242 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
11243 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
11244 Don't assume stack number fits in int.
11245 (yysplitStack): Check for storage allocation failure.
11246 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
11247 can print diagnostics on storage allocation failure. All callers
11248 changed.
11249 (yyresolveValue): Use yybool for boolean.
11250 (yyreportSyntaxError): Check for size-calculation overflow.
11251 This code is taken from yacc.c.
11252 (yyparse): Check for storage allocation errors when allocating
11253 the initial stack.
11254
11255 2005-07-05 Akim Demaille <akim@epita.fr>
11256
11257 Extract calc++ from the documentation.
11258 * doc/bison.texinfo (Calc++): Add the extraction marks.
11259 * examples/extexi: New, from the aborted GNU Programming 2E.
11260 Separate the different paragraph of a file with empty lines.
11261 * examples/Makefile: Use it to extract the whole calc++ example.
11262
11263 2005-06-24 Akim Demaille <akim@epita.fr>
11264
11265 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
11266 class typedefs.
11267
11268 2005-06-22 Akim Demaille <akim@epita.fr>
11269
11270 * doc/bison.texinfo (C++ Language Interface): First stab.
11271 (C++ Parsers): Remove.
11272
11273 2005-06-22 Akim Demaille <akim@epita.fr>
11274
11275 * data/lalr1.cc (yylex_): Honor %lex-param.
11276
11277 2005-06-22 Akim Demaille <akim@epita.fr>
11278
11279 Start a set of simple examples.

11281 * examples/calc++/calc++-driver.hh,
11282 * examples/calc++/calc++-parser.yy,
11283 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
11284 * examples/calc++/compile, examples/calc++/test: New.
11285
11286 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
11287
11288 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
11289 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
11290 which stems from the 2005-05-27 patch.
11291
11292 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
11293
11294 * data/glr.c: Modify treatment of unused parameters to permit use
11295 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
11296
11297 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
11298
11299 Fix infringement on user name space reported by Janos Zoltan Szabo.
11300 * data/yacc.c (yyparse): strlen -> yystrlen.
11301
11302 2005-05-30 Akim Demaille <akim@epita.fr>
11303
11304 * data/lalr1.cc (_): New.
11305 Translate the various messages.
11306
11307 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
11308
11309 Fix infringement on user name space reported by Bruno Haible.
11310 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
11311 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
11312 the user's name space.
11313 (alloca): Include <stdlib.h> to get it, if it's not built in.
11314 (YYMALLOC, YYFREE): Define only if needed.
11315 (malloc, free): Declare, but only if needed, as this infringes on
11316 the user name space.
11317
11318 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
11319
11320 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
11321 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
11322 with %d format.
11323 * lib/ebitset.c (min, max): Undef before defining.
11324 * lib/vbitset.c (min, max): Likewise.
11325 * lib/subpipe.c (create_subpipe): Save local variables in case
11326 vfork clobbers them.
11327
11328 2005-05-24 Bruno Haible <bruno@clisp.org>
11329
11330 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
11331 error message syntax used by gcc-4.0.
11332
11333 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
11334
11335 * README: Mention m4 1.4.3. Remove obsolete advice about
11336 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
11337
11338 * bootstrap: Remove workaround for problem I encountered with
11339 gettext 0.14.1; it seems to be fixed now.
11340
11341 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
11342
11343 * NEWS: Version 2.0a.
11344
11345 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
11346 the previous change.
11347
11348 Various maintainer cleanups.
11349 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
11350 conftest*, for benefit of CVS commands run at the same time as
11351 "configure". Add build-aux, since "bootstrap" now creates it and
11352 its subfiles.
11353 * Makefile.cfg (move_if_change): Remove.
11354 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
11355 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
11356 (po_repo, do-po-update, po-update, wget_files, get-targets):
11357 (config.guess-url_prefix, config.sub-url_prefix):
11358 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
11359 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
11360 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
11361 Remove.
11362 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
11363 this is now the recommended name.
11364 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
11365 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
11366 ylwrap. These files now go into build-aux.
11367 * config/move-if-change: Remove.
11368 * config/prev-version.txt: Bump from 1.75 to 2.0.
11369
11370 * bootstrap: Add stdio-safer, unistd-safer modules.
11371 Remove m4/glibc2.m4 (introduced by latest gnulib, but
11372 we don't need it).
11373 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
11374 fopen-safer.c, stdio-safer.h, unistd-safer.h.
11375 * lib/subpipe.c: Include "unistd-safer.h".
11376 (create_subpipe): Make sure all the newly-created
11377 file descriptors are > 2, so that diagnostics don't
11378 get sent down them (which might cause Bison to hang, in theory).
11379 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
11380 * src/files.c (xfopen): Use fopen_safer, not fopen.
11381
11382 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
11383 yesterday's yacc.c fix.
11384
11385 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
11386
11387 * data/glr.c, data/lalr1.cc: Update copyright date.
11388
11389 Fix a destructor bug reported by Wolfgang Spraul in
11390 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
11391 * data/yacc.c (yyabortlab): Don't call destructor, and
11392 don't set yychar to EMPTY.
11393 (yyoverflowlab): Don't call destructor.
11394 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
11395 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
11396 since we no longer output the message "discarding lookahead token
11397 end of input ()".
11398
11399 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
11400
11401 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
11402 fix a small glitch in debugging output.
11403 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
11404 after YY_SYMBOL_PRINT where needed.
11405
11406 (struct yyGLRState): Add some comments.
11407 (struct yySemanticOption): Add some comments.
11408 (union yyGLRStackItem): Add comment.
11409
11410 (yymergeOptionSets): Correct this to properly perform the union,
11411 avoiding infinite reported by Michael Rosien.
11412 Update comment.
11413
11414 * tests/glr-regression.at: Add test for GLR merging error reported
11415 by M. Rosien.
11416
11417 2005-05-13 Paul Eggert <eggert@cs.ucla.edu>

11455 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
11456
11457 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
11458 Problem reported by Ralf Menzel.
11459
11460 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
11461
11462 * tests/actions.at: Test that stack overflow invokes destructors.
11463 From Marcus Holland-Moritz.
11464 * data/yacc.c (yyerrlab): Move the code that destroys the stack
11465 from here....
11466 (yyreturn): to here. That way, destructors are called properly
11467 even if the stack overflows, or the user calls YYACCEPT or
11468 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
11469 (yyoverflowlab): Destroy the lookahead.
11470
11471 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
11472
11473 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
11474
11475 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
11476
11477 * NEWS: Bison-generated C parsers no longer quote literal strings
11478 associated with tokens.
11479 * src/output.c (prepare_symbols): Don't escape strings,
11480 since users don't want to see C escapes.
11481 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
11482 in diagnostics.
11483 * tests/input.at (Torturing the Scanner): Likewise.
11484 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
11485
11486 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
11487
11488 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
11489 the data size is known to be too small and we can't increase it.
11490 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
11491
11492 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
11493
11494 * src/parse-gram.y: Include quotearg.h.
11495 (string_as_id): Quote $1 before using it as a key, since the
11496 lexer no longer quotes it for us.
11497 (string_content): Don't strip quotes, since lexer no longer
11498 quotes it for us.
11499 * src/scan-gram.l: Include quotearg.h.
11500 ("\""): Omit quote.
11501 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
11502 a key, since the rest of the lexer doesn't quote it.
11503 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
11504 * tests/regression.at (Token definitions): Check for backslashes
11505 in token strings.
11506
11507 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
11508 (YYSIZE_T): Define to unsigned long int when using an older compiler.
11509 (yyparse): Revamp code to generate long syntax error message, to
11510 make it easier to translate, and to avoid problems with arithmetic
11511 overflow. Change "virtual memory" to "memory" in diagnostic, since
11512 we don't know whether the memory is virtual.
11513
11514 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
11515
11516 * NEWS: Bison-generated C parsers now use the _ macro to
11517 translate strings.
11518 * data/yacc.c (_) [!defined _]: New macro.
11519 All English strings wrapped inside this macro.
11520 * doc/bison.texinfo (Bison Parser): Document _.
11521 * po/POTFILES.in: Include src/parse-gram.c, since it now
11522 includes translateable strings that parse-gram.y doesn't.
11523
11524 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
11525
11526 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
11527 reverting the 2004-10-11 change to this function.
11528 (symbol_check_alias_consistency): Don't call symbol_type_set
11529 if the type name is already correct.
11530 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
11531
11532 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
11533
11534 * tests/regression.at (Token definitions): Don't use a token named
11535 c, as that generates a "#define c ..." that runs afoul of buggy
11536 stdlib.h that uses the identifier c as a member of struct
11537 drand48_data. Problem reported by Horst Wente.
11538
11539 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
11540
11541 * bootstrap: Change translation URL from
11542 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
11543 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
11544 redirection glitches. Problem reported by twlevo@xs4all.nl.
11545
11546 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
11547
11548 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
11549 after operands; POSIX says this isn't portable for the c99 command.
11550
11551 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
11552
11553 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
11554 immediately if a data overrun has occurred; this may help us track
11555 down what may be a spurious failure on MacOS.
11556
11557 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
11558
11559 Respond to problems reported by twlevo@xs4all.nl.
11560
11561 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
11562
11563 * src/vcg.h: Comment fix.
11564 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
11565 (G_CMAX): Change to -1 instead of INT_MAX.
11566
11567 * data/yacc.c (yyparse): Omit spaces before #line.
11568
11569 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
11570
11571 * src/tables.c (state_number_to_vector_number): Put it inside an
11572 "#if 0", since it's not currently used. Problem reported by
11573 Roland McGrath.
11574
11575 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
11576
11577 * src/output.c (escaped_output): Renamed from
11578 escaped_file_name_output, since we now use it for symbol tags as
11579 well. All uses changed.
11580 (symbol_destructors_output, symbol_printers_output):
11581 Escape symbol tags too.
11582 Problem reported by Matyas Forstner in
11583 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
11584
11585 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
11586 not needed.
11587 * src/output.c (user_actions_output, token_definitions_output,
11588 symbol_destructors_output, symbol_printers_output): Likewise.
11589 * src/reader.c (prologue_augment): Likewise.
11590 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
11591
11592 * src/vcg.c (output_edge): Don't quote linestyle arg.
11593 Problem reported by twlevo@xs4all.nl.
11594
11595 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
11596
11597 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
11598 example, reported by Derek M Jones. Also, make the example even
11599 more outrageous, to better illustrate how bad the problem is.
11600
11601 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
11602
11603 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
11604 putsym. Typo reported by Sebastian Piping.
11605
11606 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
11607
11608 * doc/bison.texinfo (Language and Grammar): some -> same
11609 (Epilogue): int he -> in the
11610 Typos reported by Sebastian Piping via Justin Pence.
11611
11612 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
11613
11614 * tests/glr-regression.at (Improper handling of embedded actions
11615 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
11616 embedded actions and $-N in GLR parsers", work around an Autoconf bug
11617 with dollar signs in test names.
11618 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
11619 for a similar reason.
11620
11621 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
11622
11623 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
11624 wants to redefine G_VIEW.
11625
11626 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
11627
11628 * src/vcg.c (get_view_str): Remove case for normal_view.

11630
11631 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
11632
11633 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
11634 Problem reported by twlevo@xs4all.nl.
11635
11636 * doc/bison.texinfo: Change @dircategory from "GNU programming
11637 tools" to "Software development". Requested by Richard Stallman
11638 via Karl Berry.
11639
11640 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
11641
11642 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
11643 Problem reported by twlevo@xs4all.nl.
11644
11645 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
11646
11647 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
11648 keyword; it's not needed with modern compilers, and it doesn't
11649 affect correctness with older compilers. Suggested by
11650 twlevo@xs4all.nl.
11651
11652 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
11653
11654 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
11655 gcc -Wswitch-default.
11656 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
11657 * data/yacc.c (yyparse): Likewise.
11658
11659 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
11660
11661 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
11662 already. Let config.h define any nonstandard values.
11663
11664 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
11665
11666 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
11667 for the benefit of slower hosts. Problem reported by
11668 Nelson H. F. Beebe.
11669
11670 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
11671
11672 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
11673 being defined and not used.
11674 * data/lalr1.cc (yyparse): Likewise.
11675 Use "if (false)" rather than "if (0)".
11676
11677 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
11678
11679 * TODO: Mention that we should allow NUL bytes in tokens.
11680
11681 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
11682
11683 * src/scan-skel.l (<<EOF>>): Don't close standard output.
11684 Problem reported by Hans Aberg.
11685
11686 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
11687
11688 * src/getargs.c (version): Happy new year; update overall
11689 program copyright date from 2004 to 2005.
11690
11691 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
11692 Problem reported by Hans Aberg.
11693 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
11694 (Output file names.): Add a test for the case when standard output
11695 is closed.
11696
11697 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
11698
11699 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
11700 to fix an oversight in the Bison 2.0 manual.
11701
11702 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
11703
11704 * NEWS: Version 2.0. Reformat the existing news items since
11705 1.875, so that related items are grouped together.
11706 * configure.ac (AC_INIT): Bump version to 2.0.
11707 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
11708
11709 * tests/torture.at (Exploding the Stack Size with Alloca): Set
11710 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
11711 otherwise, we're not testing alloca. Unfortunately there's no
11712 simple way to consult HAVE_ALLOCA here.
11713
11714 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
11715 for yymsg, too.
11716
11717 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
11718 hand. This avoids a warning about comparing int to size_t when
11719 GCC warnings are enabled.
11720
11721 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
11722
11723 * NEWS: Bison-generated parsers no longer default to using the
11724 alloca function (when available) to extend the parser stack, due
11725 to widespread problems in unchecked stack-overflow detection.
11726 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
11727 responsibility to set it to a positive value. This lets the user
11728 specify a value that is not a preprocessor constant.
11729 * data/yacc.c (YYMAXDEPTH): Likewise.
11730 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
11731 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
11732 to be a compile-time constant. However, explain the constraints on it.
11733 Also, explain the constraints on YYINITDEPTH.
11734 (Table of Symbols): Explain that alloca is no longer the default.
11735 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
11736 to 1.
11737
11738 * doc/bison.texinfo (Location Default Action): Mention that n must
11739 be zero when k is zero. Suggested by Frank Heckenbach.
11740
11741 2004-12-22 Akim Demaille <akim@epita.fr>
11742
11743 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
11744 (parser::state_type, parser::semantic_type, parser::location_type):
11745 Private, not public.
11746 (parser::parse): Return ints, not bool.
11747 Returning a bool introduces a problem: 0 corresponds to false, and
11748 it seems weird to return false on success. Returning true changes
11749 the conventions for yyparse.
11750 Alternatively we could return void and send an exception.
11751 There is no clear consensus (yet?).
11752 (state_stack, semantic_stack, location_stack): Rename as...
11753 (state_stack_type, semantic_stack_type, location_stack_type): these.
11754 Private, not public.
11755 * tests/c++.at: New.
11756 * tests/testsuite.at, tests/Makefile.am: Adjust.
11757
11758 2004-12-21 Akim Demaille <akim@epita.fr>
11759
11760 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
11761
11762 2004-12-21 Akim Demaille <akim@epita.fr>
11763
11764 Don't impose std::string for filenames.
11765
11766 * data/lalr1.cc (b4_filename_type): New.
11767 (position::filename): Use it.
11768 (parser.hh): Move the inclusion of stack.hh and location.hh below
11769 the user code, so that needed headers for the filename type can be
11770 included first.
11771 Forward declare them before the user code.
11772 * tests/Makefile.am (check-local, installcheck-local): Pass
11773 TESTSUITEFLAGS to the TESTSUITE.
11774
11775 2004-12-20 Akim Demaille <akim@epita.fr>
11776
11777 Use more STL like names: my_class instead of MyClass.
11778
11779 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
11780 (SemanticStack, SemanticType, StateStack, StateType)
11781 (TokenNumberType, Stack, Slice, Traits, Parser::location)
11782 (Parser::value): Rename as...
11783 (location_stack, location_type, rhs_number_type, semantic_stack)
11784 (semantic_type, state_stack, state_type, token_number_type, stack)
11785 (slice, traits, parser::yylloc, parser::yylval): these.
11786
11787 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
11788
11789 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
11790
11791 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
11792 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
11793
11794 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
11795
11796 Remove uses of 'short int' and 'unsigned short int'. This raises
11797 some arbitrary limits. It uses more memory but nowadays that's
11798 not much of an issue.
11799
11800 This change does not affect the generated parsers; that's a different
11801 task, as some users will want to conserve memory there.
11802
11803 Ideally we should use size_t to represent all object counts, and
11804 something like ptrdiff_t to represent signed differences of object
11805 counts; but that will require more code-cleanup than I have the
11806 time to do right now.
11807
11808 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
11809 Use size_t, not int or short int, to count objects.
11810 * src/closure.c (nritemset, closure): Likewise.
11811 * src/closure.h (nritemset, closure): Likewise.
11812 * src/nullable.c (nullable_compute): Likewise.
11813 * src/print.c (print_core): Likewise.
11814 * src/print_graph.c (print_core): Likewise.

11828
11829 2004-12-17 Akim Demaille <akim@epita.fr>
11830
11831 * data/lalr1.cc: Extensive Doxygenation.
11832 (error_): Rename as...
11833 (error): this, since it is visible to the user.
11834 Adjust callers.
11835 (Parser::message): Now an automatic variable from...
11836 (Parser::yyreport_syntax_error_): here.
11837 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
11838 Parser::error.

11840
11841 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
11842
11843 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
11844 Parenthesize rhs to avoid obscure problems with mistakes like
11845 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
11846 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
11847 b4_rhs_location): Likewise.

11849 b4_rhs_location): Likewise.
11850
11851 2004-12-16 Akim Demaille <akim@epita.fr>
11852
11853 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
11854 yacc.c: be sure to stay within yycheck_.
11855 * tests/actions.at: Re-enable C++ tests.
11856
11857 2004-12-16 Akim Demaille <akim@epita.fr>

11864 Use #define to handle the %name-prefix.
11865
11866 * data/glr.c, data/yacc.c: Comment changes.
11867 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
11868 so that one can refer to yylex in the parser file, and have it
11869 renamed, as is the case with other skeletons.
11870
11871 2004-12-16 Akim Demaille <akim@epita.fr>
11872
11873 Move lalr1.cc internals into yy*.

11892
11893 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
11894
11895 Fix some problems reported by twlevo at xs4all.
11896 * src/symtab.c (symbol_new): Report an error if the input grammar
11897 contains too many symbols. This is better than calling abort() later.
11898 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
11899 (struct node, struct graph):
11900 Rename member expand to stretch. All uses changed.
11901 (struct graph): Remove member layoutalgorithm. All uses removed.
11902 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
11903 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
11904 All uses changed.
11905 (N_STRETCH): Rename from N_EXPAND. All uses changed.
11906
11907 2004-12-15 Akim Demaille <akim@epita.fr>
11908
11909 * data/lalr1.cc: Normalize /** \brief ... */ to ///.

11912 (report_syntax_error_, translate_): Rename as...
11913 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
11914 (yypop_, yyreport_syntax_error_, yytranslate_): this.
11915
11916 2004-12-15 Akim Demaille <akim@epita.fr>
11917
11918 * data/lalr1.cc (lex_): Rename as...
11919 (yylex_): this.
11920 Move the trace here.
11921 Take the %name-prefix into account.
11922 Reported by Alexandre Duret-Lutz.
11923
11924 2004-12-15 Akim Demaille <akim@epita.fr>
11925
11926 Simplify the C++ parser constructor.
11927
11928 * data/lalr1.cc (debug_): Rename as...
11929 (yydebug_): so that the parser's internals are always in the yy*
11930 pseudo namespace.
11931 Adjust uses.
11932 (b4_parse_param_decl): Remove the leading comma as it is now only
11933 called as unique argument list.
11934 (Parser::Parser): Remove the constructor accepting a location and
11935 an initial debugging level.
11936 Remove from the other ctor the argument for the debugging level.
11937 (debug_level_type, debug_level, set_debug_level): New.
11938
11939 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
11940 constructor calls.
11941
11942 2004-12-15 Akim Demaille <akim@epita.fr>
11943
11944 Remove b4_root related material: failure experiment
11945 (which goal was to allow to derive from a class).
11946
11947 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
11948 definitions and uses.
11949
11950 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
11951
11952 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
11953 not 2, since it's not portable to subtract 1 from the start of an
11954 array. The new item 0 is never set or used. All uses changed.
11955
11956 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
11957 the default definition of YYLLOC_DEFAULT. Problem reported
11958 by Frank Heckenbach.
11959
11960 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
11961
11962 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
11963 the normal case and one for the error case. Just use the
11964 first one uniformly. Problem reported by Frank Heckenbach.
11965 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
11966 use exactly the same macro in both places.
11967 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
11968 so that the normal-case YYRHSLOC works for the error case too.
11969 All uses changed.
11970 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
11971 (YYLLOC_DEFAULT): Use the same macro as glr.c.
11972 * doc/bison.texinfo (Location Default Action): Don't claim that
11973 we have an array of locations. Use the same macro for both glr
11974 and lalr parsers. Mention YYRHSLOC. Mention what happens when
11975 the index is 0.
11976
11977 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
11978

11989
11990 * src/relation.h (relation_print, relation_digraph):
11991 Relation sizes are of type relation_node, not size_t (this is
11992 merely a doc fix, since the two types are equivalent).
11993 (relation_transpose): Relation sizes are of type relation_node,
11994 not int.
11995 * src/relation.c: Likewise.
11996 (top, infinity): Now of type relation_node, not int.
11997 (traverse, relation_transpose): Use relation_node, not int.
11998
11999 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
12000 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
12001 (yyparse): Remove unused local introduced in 2004-10-25 patch.
12002
12003 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
12004 specifying whether the test should be skipped. Use it tp
12005 specify that the [%defines %skeleton "lalr1.cc"] tests currently
12006 fail on some hosts, and should be skipped.
12007
12008 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
12009
12010 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
12011 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
12012 unless otherwise specified below.
12013
12014 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
12015 to allocate kernel_base, kernel_items, kernel_size, since
12016 they needn't be initialized to 0.
12017 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
12018 * src/closure.c (new_closure): Likewise, for itemset.
12019 * src/derives.c (derives_compute): Likewise, for delts, derives, q.

12021 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
12022 (build_relations): Likewise for edge, states1, includes.
12023 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
12024 * src/reader.c (packgram): Likewise, for ritem, rules.

12036 (tables_generate): Likewise for width.
12037
12038 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
12039 for initial core. Just have a separate core, so we needn't worry
12040 about whether kernel_size and kernel_base are initialized.
12041
12042 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
12043 kernel_size, kernel_items): Remove unnecessary initialization.
12044 * src/conflicts.c (conflicts): Likewise.
12045 * src/derives.c (derives): Likewise.
12046 * src/muscle_tablc (muscle_insert): Likewise.
12047 * src/relation.c (relation_digraph): Likewise.
12048 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
12049 conflrow, conflict_table, conflict_list, table, check):
12050 Likewise.
12051
12052 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
12053 This is because all callers pass unsigned int.
12054 * src/closure.h (new_closure): Likewise.
12055
12056 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
12057 (build_relations): Initialize includes[i] in all cases.
12058 * src/reader.c (packgram): Always initialize rules[ruleno].prec
12059 and rules[ruleno].precsym. Initialize members in order.
12060 * src/relation.c (relation_transpose): Always initialize new_R[i]
12061 and end_R[i].
12062 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
12063
12064 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
12065 conflict_list[0] was always 0, but now it isn't initialized.
12066
12067 * src/table.c (table_grow): When conflict_table grew, the grown
12068 area wasn't cleared. Fix this.
12069
12070 * lib/.cvsignore: Add strdup.c, strdup.h.
12071 * m4/.cvsignore: Add strdup.m4.
12072
12073 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
12074
12075 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
12076 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
12077 GOTO_NUMBER_MAXIMUM, since we occasionally compute
12078 ngotos + 1 without checking for overflow.
12079 (build_relations): Use END_NODE, not -1, to denote end of edges.
12080 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
12081 build_relations): Use goto_number, not int, for goto numbers.
12082 * src/tables.c (save_column, default_goto): Likewise.
12083
12084 2004-11-23 Akim Demaille <akim@epita.fr>
12085
12086 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
12087 of #defining from yystype.
12088 Don't typedef yystype, C++ does not need it.
12089 This lets it possible to forward declare it as union.
12090
12091 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
12092
12093 * bootstrap (gnulib_modules): Add extensions.
12094 Problem reported by Jim Meyering.
12095
12096 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
12097
12098 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
12099 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
12100 src/system.h, src/tables.c: XFREE -> free, to accommodate
12101 recent change to gnulib xalloc.h.
12102 Problem reported by Jim Meyering.
12103
12104 2004-11-17 Akim Demaille <akim@epita.fr>
12105
12106 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
12107
12108 2004-11-17 Akim Demaille <akim@epita.fr>,
12109 Alexandre Duret-Lutz <adl@gnu.org>
12110
12111 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
12112 changes.
12113 (YYCDEBUG): Adjust.
12114 Use it instead of cdebug_.
12115 (Parser::debug_stream, Parser::set_debug_stream): New.
12116 (Parser::symprint_): Define cdebug_ for temporary backward
12117 compatibility.
12118 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
12119 debug_stream ().
12120
12121 2004-11-17 Akim Demaille <akim@epita.fr>
12122
12123 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
12124 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
12125 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
12126 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.

12131 Problem reported by Frank Heckenbach.
12132
12133 2004-10-25 Akim Demaille <akim@epita.fr>
12134
12135 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
12136 Introduce another definition to address simple location arrays.
12137 (yyGLRStack): New member: yyerror_range.
12138 (yyrecoverSyntaxError, yyparse): Update it.
12139 (yyrecoverSyntaxError): Use it when shifting the error token to
12140 have an accurate range, equivalent to the one computed by both
12141 yacc.c and lalr1.cc.
12142 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
12143 that column numbers start at column 0, as per GNU Coding
12144 Standards, the others tests, and the doc.
12145 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
12146 Adjust to the above change (first column is 0).
12147 And adjust the location of the "<error>", now covering the whole
12148 line.
12149
12150 2004-10-22 Akim Demaille <akim@epita.fr>
12151 and Paul Eggert <eggert@cs.ucla.edu>
12152
12153 Remove some arbitrary limits on goto numbers and relations.
12154 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
12155 initial values, since they're never used.
12156 (set_goto_map): ngotos is now unsigned, so test for overflow
12157 by seeing whether it wraps around to zero.
12158 * src/lalr.h (goto_number): Now size_t, not short int.
12159 (GOTO_NUMBER_MAXIMUM): Remove.
12160 * src/relation.c (relation_print, traverse, relation_transpose):
12161 Check for END_NODE rather than looking at sign.
12162 * src/relation.h (END_NODE): New macro.
12163 (relation_node): Now size_t, not short int.
12164
12165 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
12166
12167 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
12168 keyword, not an identifier. Problem reported by Baron Schwartz in
12169 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
12170
12171 2004-10-11 Akim Demaille <akim@epita.fr>
12172
12173 * src/symtab.c (symbol_check_alias_consistency): Also check
12174 type names, destructors, and printers.
12175 Reported by Alexandre Duret-Lutz.
12176 Recode the handling of associativity and precedence in terms
12177 of symbol_precedence_set.
12178 Accept no redeclaration at all, not even equal to the previous
12179 value.
12180 (redeclaration): New.
12181 Use it to factor redeclaration complaints.
12182 (symbol_make_alias): Don't set the type of the alias, let
12183 symbol_check_alias_consistency do it as for other features.
12184 * src/symtab.h (symbol): Add new member prec_location, and
12185 type_location.
12186 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
12187 * tests/input.at (Incompatible Aliases): New.
12188
12189 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
12190
12191 .cvsignore fixes to accommodate gnulib changes,
12192 and the practice of naming build directories "_build".
12193 * .cvsignore: Add "_*". Sort.
12194 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
12195 * m4/.cvsignore: Add "*_gl.m4".
12196
12197 2004-10-06 Akim Demaille <akim@epita.fr>
12198
12199 * src/parse-gram.y (add_param): Fix the truncation of trailing
12200 spaces.
12201
12202 2004-10-05 Akim Demaille <akim@epita.fr>
12203
12204 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
12205 whether the reducion was empty or not. This leaves room to
12206 improve the use of YYLLOC_DEFAULT in such a case.
12207 lalr1.cc is still experimental, so changing this is acceptable.
12208 And finally, there are probably not many users who changed the
12209 handling of locations in GLR, so changing is admissible too.
12210
12211 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
12212 empty reduction, set @$ to an empty location ending the previously
12213 stacked symbol.
12214 Adjust uses to make sure the code is triggered on empty
12215 reductions.
12216 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
12217 expected output: empty reductions have empty locations.
12218
12219 2004-09-29 Akim Demaille <akim@epita.fr>
12220
12221 * data/lalr1.cc: Move towards a more standard C++ coding style
12222 for templates: Class < T > -> Class<T>.
12223
12224 2004-09-29 Akim Demaille <akim@epita.fr>
12225
12226 * data/lalr1.cc: Reinstall the former ctor, for sake of
12227 compatibility, but warn it will be removed.
12228 Move towards a more standard C++ coding style (i.e., type *var ->
12229 type* var).
12230
12231 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
12232
12233 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
12234 since it's less likely to work if NULs are involved in the future.
12235
12236 2004-09-27 Akim Demaille <akim@epita.fr>
12237
12238 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
12239
12240 2004-09-27 Akim Demaille <akim@epita.fr>
12241
12242 * data/lalr1.cc (b4_parse_param_decl_1): New.
12243 (b4_parse_param_decl): Use it to have different names between attribute
12244 and argument names.
12245 (b4_cc_constructor_call): Likewise.
12246
12247 2004-09-24 Akim Demaille <akim@epita.fr>
12248
12249 * src/parse-gram.y (add_param): Strip the leading and trailing
12250 blanks from a formal argument declaration.
12251 (YY_LOCATION_PRINT): New.
12252
12253 2004-09-24 Akim Demaille <akim@epita.fr>
12254
12255 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
12256 after the location.
12257
12258 2004-09-24 Akim Demaille <akim@epita.fr>
12259
12260 * doc/bison.texinfo (Table of Symbols): Sort.
12261
12262 2004-09-21 Akim Demaille <akim@epita.fr>
12263
12264 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
12265 the useless parentheses.
12266 Suggested by Paul Eggert.
12267
12268 2004-09-20 Akim Demaille <akim@epita.fr>
12269
12270 Let the initial-action act on the look-ahead, and use it for the
12271 "initial push" (corresponding to an hypothetical beginning-of-file).
12272 And let lalr1.cc honor %initial-action.
12273
12274 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
12275 example.
12276 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
12277 (Parser::Parser): Remove the ctor that used to initialize it.
12278 (Parser::parse): Like in the other skeletons, issue the "starting
12279 parse" message before any action.
12280 Honor %initial-action.
12281 Initialize the stacks with the lookahead.
12282 * data/yacc.c: Let $$ and @$ in %initial-action designate the
12283 look-ahead.
12284 Push them in the stacks.
12285 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
12286
12287 2004-09-20 Akim Demaille <akim@epita.fr>
12288
12289 * doc/bison.texinfo (Initial Action Decl): New.
12290
12291 2004-09-20 Akim Demaille <akim@epita.fr>
12292
12293 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
12294 clearer criterion to define it.
12295 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
12296 When reducing on an empty RHS, use the latest stacked location as
12297 location.
12298 yylloc is not always available.
12299 * data/glr.c: Likewise.
12300 Also, honor initial-actions.
12301
12302 2004-09-20 Akim Demaille <akim@epita.fr>
12303
12304 * data/yacc.c (YY_LOCATION_PRINT): New.
12305 Define when we know YYLTYPE's structure, i.e., when the default
12306 YYLLOC_DEFAULT is used.
12307 * data/c.m4 (b4_yysymprint_generate): Use it.
12308 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
12309 value of the result.
12310 (error_start_): Replace with...
12311 (error_range_): this location array.
12312 This allows to replace code relying on the implementation of
12313 locations by portable code.
12314 * data/yacc.c (yylerrsp): Replace with...
12315 (yyerror_range): this.
12316 Every time a token is popped, update yyerror_range[0], to have an
12317 accurate location for the error token.
12318 * data/glr.c (YY_LOCATION_PRINT): New.
12319 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
12320 deference a pointer.
12321 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
12322 report the location in %printers.
12323
12324 * src/scan-skel.l: Instead of abort, report error messages to ease
12325 understanding skeleton scanning failures.
12326
12327 2004-09-16 Akim Demaille <akim@epita.fr>
12328
12329 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
12330 (iterator, const_iterator): these, to be more in the C++ spirit.
12331 Also, return reverse iterators so that when displaying the stack
12332 we display its bottom first.
12333 (Parser::stack_print_, Parser::reduce_print_): Match the messages
12334 from yacc.c.
12335 We should probably use vector here though.
12336
12337 2004-09-16 Akim Demaille <akim@epita.fr>
12338
12339 Have more complete shift traces.
12340
12341 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
12342 to report Shifts instead of ad hoc YYDPRINTF invocations,
12343 including for the error token.
12344 * data/lalr1.cc (symprint_): Output the location.
12345 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
12346 output the location within the %printer.
12347 Activate GLR tests, at least to make sure they compile properly.
12348 They still don't pass though.
12349 * tests/calc.at: Adjust expect verbose output, since now "Entering
12350 state..." is on a different line than the "Shifting" message.
12351
12352 2004-09-08 Akim Demaille <akim@epita.fr>
12353
12354 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
12355 Bison directive from the Bison file to the invocation of this
12356 macro, so that these directives are passed to
12357 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
12358 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
12359 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
12360 the extra Bison directives instead of the whole series.
12361 Change the grammar so that there are recoverable errors, and
12362 unrecoverable errors. Now we can have the parser give up before
12363 consuming the whole input. As a result we now can observe that
12364 the lookahead is freed when needed.
12365 Change the parser source to parse argv[1] instead of a hard coded
12366 string.
12367 Simplify yylex, and give a value and location to EOF.
12368 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
12369 passed directives already coded in the file.
12370 Add some tests to check the location of "error".
12371 For some tests, the C++ parser is correct, and not yacc.c.
12372 For other tests, they provide different, but unsatisfying, values,
12373 so keep the C++ value so that at least one parser is "correct"
12374 according to the test suite.
12375 (Actions after errors): Remove, this is subsumed by the
12376 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
12377
12378 2004-09-06 Akim Demaille <akim@epita.fr>
12379
12380 * data/lalr1.cc: Adjust the indentation of the labels.
12381 (Parser::pop): New.
12382 Use it.
12383
12384 2004-09-06 Akim Demaille <akim@epita.fr>
12385
12386 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
12387 argument, an informative message.
12388 Call YY_SYMBOL_PRINT.
12389 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
12390 * data/lalr1.cc (destruct_): Likewise.
12391 In addition, no longer depend on b4_yysymprint_generate and
12392 b4_yydestruct_generate to generate these functions, do it "by
12393 hand".
12394
12395 2004-09-03 Akim Demaille <akim@epita.fr>
12396
12397 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
12398 invoked, yydestruct the lookahead.
12399 * tests/calc.at (Calculator $1): Update the expected lengths of
12400 traces: there is an added line for the discarded lookahead.
12401 * doc/bison.texinfo (Destructor Decl): Some rewording.
12402 Define "discarded" symbols.
12403
12404 2004-09-02 Akim Demaille <akim@epita.fr>
12405
12406 * data/lalr1.cc (translate_, destruct_): No reason to be static.
12407
12408 2004-09-02 Akim Demaille <akim@epita.fr>
12409
12410 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
12411 (YYDSYMPRINTF): Rename as...
12412 (YY_SYMBOL_PRINT): this.
12413 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
12414 two.
12415 Use it instead of direct symprint_ calls.
12416 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
12417 one.
12418
12419 2004-09-02 Akim Demaille <akim@epita.fr>
12420
12421 * data/lalr1.cc (b4_yysymprint_generate): New.
12422 (symprint_): New member function, defined when YYDEBUG.
12423 Use it consistently instead of token/nterm debugging output by
12424 hand.
12425 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
12426 %printer calls to use cdebug_ when using lalr1.cc.
12427
12428 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
12429
12430 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
12431 with #ifdef YYDEBUG.
12432
12433 2004-08-26 Akim Demaille <akim@epita.fr>
12434
12435 * doc/bison.texinfo (Implementing Loops): Rename as...
12436 (Implementing Gotos/Loops): this.
12437
12438 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
12439
12440 Adjust to latest gnulib.
12441 * bootstrap (gnulib_modules): Add xalloc-die.
12442 Set LC_ALL=C so that file names sort consistently.
12443 Prefer the gnulib copies of gettext.m4, glibc21.m4,
12444 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
12445 uintmax_t.m4, ulonglong.m4.
12446 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
12447 po.m4 since we are now using _gl.m4 instead.
12448
12449 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
12450
12451 * src/scan-action.l: Remove. Scanning of semantic actions is
12452 handled in scan-gram.l.
12453
12454 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
12455
12456 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
12457
12458 * src/location.h (struct): The file member is a uniqstr.
12459 (equal_boundaries): Use UNIQSTR_EQ for comparison.
12460
12461 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
12462
12463 Fix bug with non-%union parsers that have printers or destructors,
12464 which led to a Bison core dump. Reported by Peter Fales in
12465 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
12466
12467 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
12468 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
12469 not to our own type.
12470 * src/output.c (symbol_destructors_output, symbol_printers_output):
12471 Don't assume %union.
12472 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
12473 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
12474 UNION-FLAG. All callers changed.
12475 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
12476 Use type char, not unsigned int, when declaring an array of char;
12477 this lets us remove a cast.
12478 (Printers and Destructors): Add non-%union test cases.
12479
12480 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
12481
12482 * doc/bison.texinfo: Minor editorial changes, mostly to the new
12483 GLR writeups. E.g., avoid frenchspacing and the future tense,
12484 change "lookahead" to "look-ahead", and change "wrt" to "with
12485 respect to".
12486
12487 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12488
12489 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
12490 New sections, split off from the GLR Parsers section. Put the new
12491 Simple GLR Parser near the start of the GLR section, for clarity.
12492 Rewrite connective text.
12493
12494 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
12495
12496 * doc/bison.texinfo (Simple GLR Parsers): New section.
12497
12498 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
12499
12500 * NEWS, TODO, doc/bison.texinfo:
12501 Use "look-ahead" instead of "lookahead", to be consistent.
12502 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
12503 while we're fixing "look-ahead".
12504 * src/conflicts.c (shift_set): Renamed from shiftset.
12505 (look_ahead_set): Renamed from lookaheadset.
12506 * src/print.c: Likewise.
12507 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
12508 name for "lookahead".

12522
12523 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
12524
12525 * README: Update location of patched M4 distribution.
12526
12527 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
12528
12529 Don't assume the C++ compiler takes the same arguments as the C compiler
12530 (trivial change).
12531 * configure.ac (O0CXXFLAGS): New var.
12532 * tests/atlocal.in (CXXFLAGS): Use it.
12533
12534 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
12535
12536 Fix some "make check" problems with C++ reported by
12537 Albert Chin-A-Young for Tru64 C++ in this thread:
12538 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
12539
12540 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
12541 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
12542 Output to a .cc file for C++, not to a .c file.
12543 * tests/calc.at (AT_CHECK_CALC): Likewise.
12544 * tests/regression.at (AT_CHECK_DANCER): Likewise.
12545 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
12546
12547 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
12548

12551
12552 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
12553
12554 Spent a few hours checking out which prerequisite versions the
12555 current sources actually require. I went all the way back to
12556 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
12557 a seemingly endless set of combinations of versions more recent
12558 than that. The bottom line is that the current sources require
12559 fairly recent versions of the build tools, and it'll be some work
12560 to change this.
12561 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
12562 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
12563 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
12564 Add comments explaining why those particular versions are
12565 currently needed.
12566
12567 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
12568 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
12569 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
12570
12571 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
12572 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
12573
12574 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
12575
12576 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
12577 0.11.5. Suggested by Bruno Haible.
12578 * bootstrap: Remove gettext version checking.
12579
12580 * doc/bison.texinfo (Decl Summary): Also mention that %union
12581 can depend on prerequisite types. Problem reported by Tim
12582 Van Holder.
12583
12584 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
12585
12586 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
12587 * README-alpha: Don't tell people not to package this.
12588
12589 * bootstrap: Don't assume $(...) works; use `...` instead.
12590 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
12591 gettext better.
12592
12593 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
12594 put into the -d output file, and mention what to do if YYSTYPE is
12595 defined as a macro.
12596
12597 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
12598
12599 Undo change made earlier today: it caused autopoint to not bring
12600 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
12601 autopoint's.
12602
12603 * bootstrap: Check that gettext version matches what's in
12604 configure.ac. Warn users to ignore robots.txt ERROR 404.
12605 * bootstrap: Undo today's earlier change (logged below).
12606 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
12607
12608 The gettext version checking is causing more trouble than it's
12609 curing; remove it. Problem reported by Paul Hilfinger.
12610
12611 * bootstrap: Issue a warning that one can expect a message
12612 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
12613 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
12614
12615 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
12616
12617 Ensure that the C++ compiler used for testing actually works on a
12618 simple test program; if not, skip the C++-related tests. Problem
12619 reported by Vin Shelton in:
12620 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
12621
12622 * m4/cxx.m4: New file.
12623 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
12624 * tests/atlocal.in (BISON_CXX_WORKS): Add.
12625 * tests/local.at (AT_COMPILE_CXX): Use it.
12626
12627 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
12628
12629 * data/glr.c (yylloc): Output this macro even if locations are not
12630 being generated, as the GLR parser needs it even in that case.
12631 Problem reported by Troy A. Johnson
12632 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
12633
12634 * configure.ac (AC_INIT): Update to 1.875e.
12635
12636 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
12637
12638 * NEWS: Version 1.875d.
12639 * configure.ac (AC_INIT): Likewise.
12640 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
12641
12642 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
12643 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
12644 lalr1.cc runs afoul of the first, and the last two are no longer
12645 supported by GCC 3.4.0.
12646 * README: Mention GNU m4 1.4 or later; mention m4 patches.
12647 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
12648
12649 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
12650
12651 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
12652 unsigned int, for compatibility with latest gnulib hash module.
12653 * src/state.c (state_hash, state_hasher): Likewise.
12654 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.

12660
12661 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
12662 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
12663 character and string literals.
12664 (unexpected_end): New function.
12665 (unexpected_eof): Use it.
12666 (unexpected_newline): New function.
12667 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
12668 actions.
12669
12670 * NEWS: Document %expect-rr.
12671

12674 Remove more 'intl'-related files.
12675 Don't DEFUN AM_INTL_SUBDIR twice.
12676

12678 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
12679 strtoul.c.
12680 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
12681 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
12682 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
12683 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
12684 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
12685 * src/.cvsignore: Add *.output.
12686
12687 * src/parse-gram.y: Put copyright notice inside %{ %} so it
12688 gets copied to the output file.
12689
12690 2004-04-28 Paul Eggert <eggert@twinsun.com>
12691
12692 Get files from the gnulib and po repositories, instead of relying
12693 on them being in our CVS. Upgrade to latest versions of gnulib
12694 and Automake.
12695
12696 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
12697 * bootstrap: Bootstrap from gnulib and po repositories.
12698 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
12699 * README-cvs: Document these changes. Remove version numbers from
12700 mentions of build tools, since they change so often. Mention Flex.
12701
12702 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
12703 (gl_USE_SYSTEM_EXTENSIONS): Add.
12704 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
12705 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
12706 does this for us.
12707 (AC_ISC_POSIX): Remove; we no longer support this
12708 ancient OS, as it gets in the way of latest Autoconf & gnulib.
12709 (AC_HEADER_STDC): Remove: we now assume C89 or better.
12710 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
12711 Do not check for C89 headers, except for locale.h which is used
12712 by the Yacc library and must port to K&R hosts.
12713 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
12714 Do not check for C89 functions, except for setlocale which is
12715 used by the Yacc library.
12716 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
12717 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

12719 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE,
12720 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
12721 AM_GNU_GETTEXT): Remove; now done by:
12722 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
12723 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
12724 for us.
12725
12726 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
12727 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
12728 Define to empty, as gnulib.mk will do the rest for us.
12729 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
12730 for us.
12731 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
12732 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
12733
12734 * src/files.c: Include gnulib's xstrndup.h.
12735
12736 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
12737 (REALLOC): Use xnrealloc, for likewise.
12738 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
12739 (strnlen, memrchr): Remove decls; functions no longer used.
12740 Include <stpcpy.h>.
12741
12742 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

12762 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
12763 Remove, as these files are now generated automatically
12764 by bootstrap or automake.
12765
12766 * po/ChangeLog: Remove: all but one entry was a duplicate
12767 of this file, and I moved that 2000-11-02 entry here.
12768
12769 * config/.cvsignore: Add Makefile, depcomp, install-sh.
12770 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

12779 unlocked-io.h, xalloc.h, xmalloc.c, xstrdup.c, xstrndup.c,
12780 xstrndup.h.
12781 * m4/.cvsignore: Remove Makefile, Makefile.in. Add alloca.m4,
12782 dirname.m4, dos.m4, error.m4, getopt.m4, hash.m4, mbrtowc.m4,

12786 * src/.cvsignore: Remove *_.c.
12787
12788
12789 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
12790 support it. (The latest stable gzip doesn't.)
12791
12792 2004-04-27 Paul Eggert <eggert@twinsun.com>
12793
12794 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
12795 case, as stos_ is now used by destructors due to the 2004-02-09
12796 change.
12797
12798 Remove more K&R C support.
12799 * lib/libiberty.y (PARAMS): Remove. All uses removed.
12800 * lib/subpipe.c (errno): Remove decl.
12801 Include <stdlib.h> unconditionally.
12802 (EXIT_FAILURE): Remove macro.
12803 * src/complain.c (vfprintf, strerror): Remove.
12804 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
12805 unconditionally.
12806 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
12807 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
12808 (strchr, strspn, memchr): Remove decls.

12811 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
12812 unconditionally.
12813
12814 * src/complain.c (_): Remove useless defn, as system.h defines this.
12815
12816 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
12817 with latest obstack.h.
12818 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
12819 to procedure types, as obstack.h now does that for us.
12820 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
12821
12822 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
12823 so that this include file can stand alone.
12824 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
12825 does this now. Include subpipe.h first after config.h, to
12826 test whether it can stand alone.
12827
12828 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
12829 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
12830 unused declaration.
12831
12832 * tests/synclines.at (%union synch line): Put a dummy member in
12833 the union, because empty unions aren't allowed in C. Caught
12834 by GCC 3.4.0.
12835
12836 2004-04-13 Jim Meyering <jim@meyering.net>
12837
12838 * src/conflicts.c (conflicts_print): Correct format string typo:
12839 use `%%' to produce literal `%'. (trivial change)
12840
12841 2004-03-30 Paul Eggert <eggert@twinsun.com>
12842
12843 * src/getargs.c (version): Update copyright year to 2004.
12844
12845 * data/c.m4 (b4_int_type): Use 'short int' rather than
12846 'short', and similarly for 'long', 'unsigned', etc.
12847 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
12848 yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,
12849 yy_yypstack, yydumpstack): Likewise.
12850 * data/lalr1.cc (user_token_number_max_, user_token_number_max_,
12851 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):
12852 Likewise.
12853 * data/yacc.c (b4_int_type, yyss, YYSTACK_BYTES, yysigned_char,
12854 yy_stack_print, yyparse): Likewise.
12855 * doc/bison.texinfo (Prologue, Multiple Types): Likewise.

12871 * src/state.h (state_number, transitions, errs, reductions,
12872 struct state): Likewise.
12873 * src/symtab.h (symbol_number, struct symbol): Likewise.
12874 * src/tables.c (vector_number, tally, action_number,
12875 default_goto, goto_actions): Likewise.
12876 * tests/existing.at (GNU Cim Grammar): Likewise.
12877 * tests/regression.at (Web2c Actions): Likewise.
12878
12879 * src/output.c (muscle_insert_short_int_table): Renamed from

12881
12882 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
12883
12884 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
12885 (declaration): Replace expected_conflicts with expected_sr_conflicts.
12886 Add %expect-rr rule.
12887
12888 * src/scan-gram.l: Recognize %expect-rr.
12889
12890 * src/conflicts.h (expected_sr_conflicts): Rename from
12891 expected_conflicts.
12892 (expected_rr_conflicts): Declare.
12893
12894 * src/conflicts.c (expected_sr_conflicts): Rename from
12895 expected_conflicts.
12896 (expected_rr_conflicts): Define.
12897 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
12898 for GLR parsers.
12899 Use expected_sr_conflicts in place of expected_conflicts.
12900 Warn if expected_rr_conflicts used in non-GLR parser.
12901
12902 * doc/bison.texinfo: Add documentation for %expect-rr.
12903
12904 2004-03-08 Paul Eggert <eggert@gnu.org>
12905
12906 Add support for hex token numbers. Suggested by Odd Arild Olsen in
12907 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
12908
12909 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
12910 in lalr1.cc.
12911 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
12912 * src/scan-gram.l (scan_integer): New function.
12913 ({int}): Use it.
12914 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
12915 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
12916 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
12917 Say "long int", not "long", for uniformity with GNU style.
12918
12919 2004-02-25 Paul Eggert <eggert@twinsun.com>
12920
12921 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
12922 compilers. This fixes a problem with Intel's C++ compiler being
12923 chatty, reported by Guido Trentalancia in
12924 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
12925
12926 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
12927
12928 Support %destructor and merge error locations in lalr1.cc.
12929
12930 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
12931 (Parser::stos_): Define unconditionally.
12932 (Parser::destruct_): New method. Generate its body with
12933 b4_yydestruct_generate.
12934 (Parser::error_start_): New attribute.
12935 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
12936 token which are discarded.
12937 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
12938 error_start_ when erroneous token are discarded.
12939 (Parser::parse) <yyerrlab1>: Compute the location of the error
12940 token so that it covers all the discarded tokens.
12941 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
12942 it can be called with `%skeleton "lalr1.cc"', and do that.
12943
12944 2004-02-02 Paul Eggert <eggert@twinsun.com>
12945
12946 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
12947 $(top_srcdir)/lib and ../lib. This fixes a bug reported
12948 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
12949 There's no need to mention top_builddir since Automake does that
12950 for us.
12951 (INCLUDES): Remove, as Automake says it's obsolescent.
12952 Contents migrated into AM_CPPFLAGS as described above.
12953 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
12954
12955 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
12956
12957 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
12958 (yyreportSyntaxError): Handle case where lookahead token is
12959 YYEMPTY.
12960
12961 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12962
12963 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
12964 resulting parsers are compilable with C++.
12965
12966 2003-12-23 Paul Eggert <eggert@twinsun.com>
12967
12968 * config/depcomp, config/install-sh: Sync with Automake 1.8.
12969 * src/output.c (output_skeleton): Rename local var.
12970 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
12971 Bison tokens, as this runs afoul of the 2003-10-07 change that
12972 disallowed NUL bytes in character constants or string literals.
12973
12974 * tests/local.at: Require Autoconf 2.59's Autotest.
12975 * tests/testsuite.at: Don't include local.at, since we now assume
12976 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
12977 including it.
12978 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
12979 multiple inclusion warnings.
12980
12981 2003-12-02 Akim Demaille <akim@epita.fr>
12982
12983 * doc/bison.texinfo (How Can I Reset the Parser): More about start
12984 conditions.

12992
12993 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
12994 if testsuite doesn't exist.
12995
12996 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
12997 literals, unfortunately.

13001 2003-10-05 Paul Eggert <eggert@twinsun.com>
13002
13003 * NEWS: Don't document %no-default-prec, as it's still
13004 too experimental.
13005 * doc/bison.texinfo: Document %no-default-prec only if
13006 the defaultprec flag is set. Normally it's not.
13007
13008 2003-10-04 Paul Eggert <eggert@twinsun.com>
13009
13010 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
13011 non-modifiable lvalue, instead of a modifiable one.
13012 * doc/bison.texinfo (Actions): Document that $$ can
13013 be assigned to. Do not claim that $$ and $N are
13014 array element references: user code should not rely on this.

13053 GCC warnings.
13054
13055 2003-08-26 Akim Demaille <akim@epita.fr>
13056
13057 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
13058 "<\#" to avoid magic from Gnus when posting parts of this script.

13061
13062 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
13063 (Parser::parse): here.
13064 Adjust: nerrs and errstatus is now replaced by...
13065 (Parser::nerrs_, Parser::errstatus_): New.
13066

13075
13076 When reducing initial empty rules, Bison parser read an initial
13077 location that is not defined. This results in garbage, and that
13078 affects Bison's own parser. Therefore we need (i) to extend Bison
13079 to support a means to initialize this location, and (ii) to use
13080 this CVS Bison to fix CVS Bison's parser.
13081
13082 * src/reader.h, reader.c (epilogue_augment): Remove, replace
13083 with...
13084 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
13085 * src/parse-gram.y: Adjust.
13086 (%initial-action): New.
13087 (%error-verbose): Since we require CVS Bison, there is no reason
13088 not to use it.
13089 * src/scan-gram.l: Adjust.
13090 * src/Makefile.am (YACC): New, to make sure we use our own parser.
13091 * data/yacc.c (yyparse): Use b4_initial_action.
13092
13093 2003-08-25 Akim Demaille <akim@epita.fr>
13094
13095 * doc/bison.texinfo: Don't promote stdout for error messages.
13096
13097 2003-08-25 Akim Demaille <akim@epita.fr>
13098
13099 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
13100 From Alexandre Duret-Lutz.
13101
13102 2003-08-25 Akim Demaille <akim@epita.fr>
13103
13104 Version 1.875c.
13105
13106 2003-08-25 Akim Demaille <akim@epita.fr>
13107
13108 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
13109 Use them.
13110
13111 2003-08-25 Akim Demaille <akim@epita.fr>
13112
13113 * data/lalr1.cc (Parser::reduce_print_): New.
13114 Use it.
13115
13116 2003-08-25 Akim Demaille <akim@epita.fr>
13117
13118 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
13119 error recovery loops. This patch is based on
13120 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
13121 Also, augment the similarity between lalr1.cc and yacc.c.
13122 Note: the locations of error recovery rules are not correct yet.
13123
13124 * data/lalr1.cc: Comment changes to augment the similarity between
13125 lalr1.cc and yacc.c.
13126 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
13127 (yyerrlab1): Remove, but where it used to be (now the bottom part of
13128 yyerrlab), when hitting EOF, pop the whole stack here instead of
13129 merely falling thru the default error handling mechanism.
13130 (yyerrorlab): New label, with the old contents of YYERROR,
13131 plus the following change: pop the stack of rhs corresponding
13132 to the production that invoked YYERROR. That is how Yacc
13133 behaves (required by POSIX).
13134 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
13135 fail.
13136
13137 2003-08-25 Akim Demaille <akim@epita.fr>
13138
13139 Tune local.at so that people can "autom4te -l autotest calc.at -o
13140 calc" for instance, to extract a sub test suite.
13141
13142 * tests/testsuite.at: Move the initialization, Autotest version
13143 requirement, and AT_TESTED invocation into...
13144 * tests/local.at: here.
13145 * tests/testsuite.at: Include it for compatibility with Autoconf
13146 2.57.
13147 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
13148 be ignore.
13149
13150 2003-08-04 Paul Eggert <eggert@twinsun.com>
13151
13152 Rework code slightly to avoid gcc -Wtraditional warnings.
13153 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
13154 The returned value is now stored in *YY0. All callers changed.
13155 * src/output.c (merge_output): Adjust to the above change.
13156
13157 2003-07-26 Paul Eggert <eggert@twinsun.com>
13158
13159 * data/glr.c (YYASSERT): New macro.
13160 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
13161 yyresolveStates, yyprocessOneStack):
13162 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
13163 Derived from a suggestion by Frank Heckenbach.
13164
13165 2003-07-25 Paul Eggert <eggert@twinsun.com>
13166
13167 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
13168 for portability to K&R C (after ansi2knr, presumably). See
13169 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
13170 by Frank Heckenbach, though I have omitted the structure-initialization
13171 part of his glr-knr.diff patch since I recall that the Portable
13172 C Compiler didn't require that change.
13173
13174 Let the user specify how to allocate and free memory.
13175 Derived from a suggestion by Frank Heckenbach in
13176 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
13177 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
13178 All uses of free, malloc, realloc changed to use these macros,
13179 and unnecessary casts removed.
13180 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
13181
13182 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
13183
13184 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
13185 use s.empty() rather than s == "" to test for empty string; see
13186 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
13187 (trivial change)
13188
13189 2003-06-25 Akim Demaille <akim@epita.fr>
13190
13191 * config/depcomp, config/install-sh: Update from masters.
13192
13193 2003-06-20 Paul Eggert <eggert@twinsun.com>
13194
13195 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
13196 and return properly parenthesized result.
13197 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
13198 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
13199 Remove unnecessary parentheses from uses.
13200 * doc/bison.texinfo (Location Default Action): Describe the
13201 conventions for parentheses.
13202
13203 2003-06-19 Paul Eggert <eggert@twinsun.com>
13204
13205 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
13206 yyreportTree): Do not assume that size_t is the same width as int,
13207 when printing sizes. Print sizes using an unsigned format.
13208 Problem reported by Frank Heckenbach in
13209 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
13210
13211 Port to Forte Developer 7 C compiler.
13212 * data/glr.c (struct YYLTYPE): If locations are not being used,
13213 declare a single dummy member, as empty structs do not conform
13214 to the C standard.
13215 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
13216 the Forte Developer 7 C compiler complains that end-of-loop
13217 code is not reached.
13218
13219 2003-06-17 Paul Eggert <eggert@twinsun.com>
13220
13221 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
13222 avoid warnings from picky compilers about redefinition of PARAMS.
13223
13224 2003-06-17 Paul Eggert <eggert@twinsun.com>
13225
13226 Version 1.875b.
13227
13228 * NEWS: Document 1.875b.
13229
13230 * lib/bbitset.h: Do not include config.h; that's the includer's job.
13231 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
13232 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
13233 Don't use 'index' in comments, as it's a builtin fn on some hosts.
13234 * lib/bitset_stats.c: Include gettext.h unconditionally, as
13235 per recent gettext manual's suggestion.
13236 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
13237 Use prototypes, not old-style definitions.
13238 * lib/lbitset.c (lbitset_unused_clear): Likewise.
13239 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
13240 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
13241 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
13242 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,

13244 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
13245 vbitset_or_and_cmp, vbitset_copy): Likewise.
13246
13247 * lib/libiberty.h: Do not include config.h; that's the includer's job.
13248 Do not include <stdlib.h>.

13250 (ATTRIBUTE_NORETURN): Remove.
13251 (ATTRIBUTE_UNUSED): Define unconditionally.
13252
13253 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
13254 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
13255 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.

13258 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
13259 from libbitset.
13260
13261 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
13262 `How Can I Reset @code{yyparse}', since texinfo does not allow
13263 arbitrary @ in node names.
13264
13265 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
13266 shouldn't be needed according to the gettext 0.12.1 documentation
13267 but which seem to be needed anyway: codeset.m4 glibc21.m4
13268 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
13269 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
13270 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
13271
13272 * lib/.cvsignore: Add stdbool.h.
13273 * m4/.cvsignore: Add nls.m4, po.m4.
13274
13275 Upgrade to CVS gnulib.
13276 * stdbool_.h: File renamed from stdbool.h.in.
13277 * configure.ac (AM_STDBOOL_H): Invoke this instead of
13278 AC_HEADER_STDBOOL.
13279 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
13280 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
13281 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
13282 (MOSTLYCLEANFILES): New var.
13283 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
13284 (stdbool.h): New rule.
13285 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
13286 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
13287 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
13288 m4/quote.m4: Upgrade to today's gnulib.
13289
13290 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
13291 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
13292 the tests right now.
13293 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
13294 yyerror are declared before use; C99 requires this.
13295
13296 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13297
13298 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
13299 first.
13300 (yyrecoverSyntaxError): Correct the logic for setting and testing
13301 yyerrState.
13302 Correct comment on handling EOF.
13303 Allow states with only a default reduction, rather than failing
13304 (I can't quite reconstruct why these were not allowed before).
13305
13306 Fixes to avoid problem that $-N rules in GLR parsers can cause
13307 buffer overruns, corrupting state.
13308
13309 * src/output.c (prepare_rules): Output max_left_semantic_context
13310 definition.
13311 * src/reader.h (max_left_semantic_context): New variable declaration.
13312 * src/scan-gram.l (max_left_semantic_context): Define.
13313 (handle_action_dollar): Update max_left_semantic_context.
13314 * data/glr.c (YYMAXLEFT): New definition.
13315 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
13316 (yyresolveAction): Ditto.
13317
13318 Fixes to problems with location handling in GLR parsers reported by
13319 Frank Heckenbach (2003/06/05).
13320
13321 * data/glr.c (YYLTYPE): Make trivial if locations not used.
13322 (YYRHSLOC): Add parentheses, and define only if locations used.
13323 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
13324 locations not used.
13325 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
13326 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
13327
13328 * tests/cxx-type.at: Exercise location information; update tests
13329 to differentiate output with and without locations.
13330 Remove forward declarations of yylex and yyerror---caused errors
13331 because default YYLTYPE not yet defined.
13332 Change semantic actions to compute strings, rather than printing
13333 them directly (to test proper passing of semantics values). Change
13334 output to prefix notation and update test data and expected results.
13335 (yylex): Track locations.
13336 (stmtMerge): Return value rather than printing, and include arguments
13337 in value.
13338
13339 2003-06-03 Paul Eggert <eggert@twinsun.com>
13340
13341 Avoid warnings generated by GCC 2.95.4 when Bison is
13342 configured with --enable-gcc-warnings.
13343 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
13344 yy::]b4_parser_class_name[::translate_,
13345 yy::Stack::operator[] (unsigned),
13346 yy::Stack::operator[] (unsigned) const,
13347 yy::Slice::operator[] (unsigned),
13348 yy::Slice::operator[] (unsigned) const):
13349 Rename local vars to avoid warnings.
13350 * tests/glr-regression.at (Improper handling of embedded actions
13351 and $-N in GLR parsers): Remove unused local variable from yylex.
13352 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
13353 (void) as arg when not pure, since we now assume C89 when building
13354 Bison. Pacify GCC by using parameter.
13355
13356 2003-06-02 Paul Eggert <eggert@twinsun.com>
13357
13358 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
13359 yy::Location::lines, yy::Location::columns): Rename arguments
13360 to avoid shadowing; this removes a warning generated by GCC 3.3.
13361
13362 2003-06-01 Paul Eggert <eggert@twinsun.com>
13363
13364 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
13365 to g++, as GCC 3.3 complains if you do it.
13366 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
13367 everything that WARNING_CFLAGS has, except omit warnings
13368 not suitable for C++.
13369 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
13370 * tests/atlocal.in (CXXFLAGS): New var.
13371 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
13372
13373 Fix a GLR parser bug I reported in February; see
13374 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
13375 The problem was that GLR parsers did not conform to the C standard,
13376 because actions like { $1 = $2 + $3; } expanded to expressions
13377 that invoked YYFILL in separate subexpressions, and YYFILL assigned
13378 to a local variable. The C standard says that expressions
13379 like (var = f ()) + (var = f ()) have undefined behavior.
13380 Another problem was that GCC sometimes issues warnings that
13381 yyfill and its parameters are unused.
13382
13383 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
13384 as possibly unused.
13385 (yyfill): New function.
13386 (YYFILL): Use it.
13387 (yyuserAction): Change type of yynormal to bool, so that it matches
13388 the new yyfill signature. Mark it as possibly unused.
13389
13390
13391 Follow up on a bug I reported in February, where a Bison-generated
13392 parser can loop. Provide a test case and a fix for yacc.c. I
13393 don't have a fix for lalr1.cc or for glr.c, unfortunately.
13394 The original bug report is in:
13395 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
13396
13397 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
13398 macro's size was becoming unwieldy.
13399 (yyerrlab): Do not discard an empty lookahead symbol, as this
13400 might destroy garbage.
13401 (yyerrorlab): New label, with the old contents of YYERROR,
13402 plus the following change: pop the stack of rhs corresponding
13403 to the production that invoked YYERROR. That is how Yacc
13404 behaves, and POSIX requires this behavior.
13405 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
13406 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
13407 Define 'alarm' to do nothing if unistd.h is not available.
13408 Add a new rule "exp: '-' error;" to test the above change to
13409 data/yacc.c. Use 'alarm' to abort any test taking longer than
13410 10 seconds, as it's probably looping.
13411 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
13412 Also, the new yacc.c generates two fewer diagnostics for an
13413 existing test.
13414
13415 2003-05-24 Paul Eggert <eggert@twinsun.com>
13416
13417 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
13418 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
13419 This fixes a problem reported by John Bowman when the Compaq/HP
13420 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
13421 -ansi -Wall -gall).
13422 * data/yacc.c (union yyalloc): Likewise.
13423 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
13424
13425 Switch from 'int' to 'bool' where that makes sense.
13426
13427 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
13428 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
13429 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,

13440 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
13441 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
13442 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
13443 bitset_stats_or_and_cmp): Likewise.
13444 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,

13446 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
13447 ebitset_xor_cmp): Likewise.
13448 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
13449 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
13450 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
13451 lbitset_xor_cmp): Likewise.
13452 * lib/bbitset.h: Include <stdbool.h>.
13453 (struct bitset_vtable): The following members now return bool, not
13454 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
13455 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
13456 or_and_cmp).
13457 * src/conflicts.c (count_rr_conflicts): Likewise.
13458 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
13459 All uses changed.
13460 * lib/ebitset.c (ebitset_obstack_init): Likewise.
13461 * lib/lbitset.c (lbitset_obstack_init): Likewise.
13462 * src/getargs.c (debug_flag, defines_flag, locations_flag,
13463 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
13464 graph_flag): Likewise.
13465 * src/getargs.h (debug_flag, defines_flag, locations_flag,
13466 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
13467 graph_flag): Likewise.

13470 * src/reader.c (start_flag, typed): Likewise.
13471 * src/reader.h (typed): Likewise.
13472 * src/getargs.c (LOCATIONS_OPTION): New constant.
13473 (long_options, getargs): Use it.
13474 * src/lalr.c (build_relations): Use bool, not int.
13475 * src/nullable.c (nullable_compute): Likewise.
13476 * src/print.c (print_reductions): Likewise.
13477 * src/tables.c (action_row, pack_vector): Likewise.
13478 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
13479 * src/output.c (prepare): Use it.
13480 * src/output.c (token_definitions_output,
13481 symbol_destructors_output, symbol_destructors_output): Use string,
13482 not boolean integer, to keep track of whether to output separator.
13483 * src/print_graph.c (print_core): Likewise.
13484 * src/state.c (state_rule_lookaheads_print): Likewise.
13485
13486 * config/install-sh: Sync from automake 1.7.5.
13487
13488 2003-05-14 Paul Eggert <eggert@twinsun.com>
13489
13490 * src/parse-gram.y (rules_or_grammar_declaration): Require a
13491 semicolon after a grammar declaration, in the interest of possible
13492 future changes to the Bison input language.
13493 Do not allow a stray semicolon at the start of the grammar.
13494 (rhses.1): Allow one or more semicolons after any rule, including
13495 just before "|" as required by POSIX.
13496 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
13497 grammar.
13498
13499 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
13500
13501 %parse-param support for lalr1.cc.
13502
13503 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
13504 b4_cc_constructor_calls, b4_cc_constructor_call,
13505 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
13506 definitions.
13507 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
13508 parse-param arguments.
13509 (yy::b4_parser_class_name): Declare instance variables to
13510 hold parse-param arguments.
13511 * tests/calc.at: s/value/semantic_value/ because value clashes
13512 with a member of yy::b4_parser_class_name. Adjust C++ code
13513 to handle %parse-param. Enable %parse-param test in C++.
13514
13515 2003-05-12 Paul Eggert <eggert@twinsun.com>
13516
13517 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
13518 English a bit. Fix fclose typo. Change "const char" to "char
13519 const", and use ANSI C rather than K&R for "main". Suggest
13520 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
13521 and suggest yy_switch_to_buffer.
13522
13523 2003-05-05 Paul Eggert <eggert@twinsun.com>
13524
13525 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
13526 C89. This avoids a diagnostic on compilers that define __STDC__
13527 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
13528 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
13529
13530 2003-05-03 Paul Eggert <eggert@twinsun.com>
13531
13532 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
13533 Do not overrun array bounds.
13534 This should fix a bug reported today by Olatunji Oluwabukunmi in
13535 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
13536
13537 2003-04-29 Akim Demaille <akim@epita.fr>
13538
13539 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
13540 * src/getargs.c, src/getargs.h: here, as bool, not int.
13541 (nondeterministic_parser): New.
13542 * src/parse-gram.y, src/scan-gram.l: Support
13543 %nondeterministic-parser.
13544 * src/output.c (prepare): Use nondeterministic_parser instead
13545 of glr_parser where appropriate.
13546 * src/tables.c (conflict_row, action_row, save_row)
13547 (token_actions, token_actions, pack_vector): Ditto.
13548
13549 2003-04-29 Akim Demaille <akim@epita.fr>
13550
13551 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
13552
13553 2003-04-29 Akim Demaille <akim@epita.fr>
13554
13555 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
13556 with %pure-parser and %locations to exercise the patch from Yakov
13557 Markovitch below.
13558
13559 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
13560
13561 * data/yacc.c: (b4_lex_param): Corrected for the case where
13562 %lex-param is provided and %pure-parser isn't.
13563
13564 2003-04-27 Paul Eggert <eggert@twinsun.com>
13565
13566 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
13567 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
13568 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
13569 if it is not defined.
13570 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
13571
13572 2003-04-26 Paul Eggert <eggert@twinsun.com>
13573
13574 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
13575 Declare to be of type suitable for the ninf value itself, not of
13576 type suitable for the corresponding table, since the latter might
13577 be unsigned but the ninf value might be negative. This fixes a
13578 bug reported by Alexandre Duret-Lutz in
13579 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
13580
13581 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
13582 invokes it. We shouldn't invoke it twice because it will attempt
13583 to put error.o in the archive twice. This fixes a glitch reported
13584 by Martin Mokrejs in
13585 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
13586
13587 2003-04-21 Paul Eggert <eggert@twinsun.com>
13588
13589 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
13590 to gnulib.
13591
13592 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
13593
13594 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
13595 Fix obvious typo that results in uncompilable GLR parsers
13596 when both %pure-parser and %locations are used. (trivial change)
13597
13598 2003-04-17 Paul Eggert <eggert@twinsun.com>
13599
13600 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
13601 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
13602 Do not insert the expected token via unput, as this runs afoul
13603 of a POSIX-compatibility bug in flex 2.5.31.
13604 All uses changed to BEGIN the parent state,
13605 since we no longer insert the expected token via unput.
13606 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
13607 that is no longer emitted after the above change.
13608
13609 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
13610 the first one. This change is from Paul Hilfinger, and it fixes
13611 regression reported by Werner Lemberg in
13612 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
13613
13614 (resolve_sr_conflict): Don't invoke state_errs_set
13615 unless one or more tokens have been explicitly made errors.
13616 Otherwise, the above change causes Bison to abort.
13617
13618 * tests/existing.at (GNU pic Grammar): New test case, taken from
13619 Lemberg's email.
13620
13621 2003-03-31 Akim Demaille <akim@epita.fr>
13622
13623 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
13624
13625 2003-03-31 Akim Demaille <akim@epita.fr>
13626
13627 * src/output.c (prepare_symbols): Avoid trailing spaces in the
13628 output.
13629
13630 2003-03-31 Akim Demaille <akim@epita.fr>
13631
13632 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
13633 From Paul Hilfinger.
13634
13635 2003-03-29 Akim Demaille <akim@epita.fr>
13636
13637 * m4/error.m4: Do not put under dynamic conditions some code which
13638 expansion is under static control.
13639
13640 2003-03-29 Akim Demaille <akim@epita.fr>
13641
13642 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
13643
13644 2003-03-29 Akim Demaille <akim@epita.fr>
13645
13646 * doc/bison.texinfo (Strings are Destroyed): New.
13647
13648 2003-03-13 Paul Eggert <eggert@twinsun.com>
13649
13650 * .cvsignore: Add configure.lineno.
13651 * src/.cvsignore: Add yacc.
13652 * tests/.cvsignore: Add testsuite.log.
13653 * doc/fdl.texi: Sync with latest FSF version.
13654
13655 2003-03-12 Paul Eggert <eggert@twinsun.com>
13656
13657 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
13658 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
13659 cursor, instead of leaving it undefined. This fixes a bug
13660 reported by Tim Van Holder in
13661 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
13662 * tests/input.at (Torturing the Scanner): Test the scanner on
13663 an empty input file, which was Tim Van Holder's test case.
13664
13665 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
13666 <sys/resource.h> can be included, include sys/time.h and
13667 sys/times.h first, if available. This works around the SunOS
13668 4.1.4 porting bug reported by Bruce Becker in
13669 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
13670
13671 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
13672 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
13673 AC_HEADER_SYS_WAIT.
13674
13675 Merge changes from gnulib. This was prompted because the CVS
13676 snapshot didn't build on Solaris 7 due to strnlen problems.
13677
13678 These changes need to be merged back into gnulib:
13679 * lib/hash.c: Include <stdbool.h> unconditionally.
13680 * m4/onceonly.m4 (m4_quote): New macro.
13681 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
13682 Quote AC_FOREACH variable-expansions properly.
13683 The 2003-01-03 obstack.h change also needs merging.
13684 {end of changes requiring merging}
13685
13686 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
13687 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
13688 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
13689 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
13690 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
13691 New files, imported from gnulib.
13692 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
13693 above.
13694
13695 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
13696 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
13697 gnulib sources.
13698
13699 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
13700 Add.
13701 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
13702 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
13703 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
13704 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
13705 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
13706 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
13707 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
13708 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
13709 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
13710 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
13711 (jm_PREREQ_ARGMATCH): Remove.
13712 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
13713 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
13714
13715 * src/system.h: Include <stdbool.h> unconditionally.
13716
13717 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
13718 assuming at least C89 in the bitset code for some time now.
13719
13720 2003-03-03 Akim Demaille <akim@epita.fr>
13721
13722 * ro.po: New.
13723
13724 2003-03-02 Akim Demaille <akim@epita.fr>
13725
13726 * doc/bison.texinfo (Table of Symbols): Reactivate the
13727 documentation for %lex-param, and %parse-param.
13728
13729 2003-03-02 Akim Demaille <akim@epita.fr>
13730
13731 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
13732 generate verbose error messages.
13733 Use the number of tokens as an upper bound in yytname, as it
13734 cannot be a non terminal.
13735
13736 2003-03-02 Akim Demaille <akim@epita.fr>
13737
13738 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
13739 message.
13740
13741 2003-03-02 Akim Demaille <akim@epita.fr>
13742
13743 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
13744 Use them to exercise yycheck overrun.
13745 Based on Andrew Suffield's grammar.
13746
13747 2003-03-02 Akim Demaille <akim@epita.fr>
13748
13749 Create tests/local.at for Bison generic testing macros.
13750
13751 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
13752 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
13753 This new file.
13754 * tests/calc.at (AT_CHECK_CALC): Adjust.
13755 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
13756 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
13757 * tests/local.at: here.
13758 (AT_COMPILE_CXX): Tags the tests using it as c++.
13759 Ignore the test if CXX is not functional.
13760
13761 2003-03-01 Paul Eggert <eggert@twinsun.com>
13762
13763 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
13764 not loc->end, since loc->end might contain garbage and this leads
13765 to undefined behavior on some platforms.
13766 (id_loc, token_start): Use (IF_LINTed) initial values that do not
13767 depend on *loc, so that the reader doesn't give the the false
13768 impression that *loc is initialized.
13769 (<INITIAL>"%%"): Do not bother setting code_start, since its value
13770 does not survive the return.
13771
13772 2003-03-01 Akim Demaille <akim@epita.fr>
13773
13774 * src/scan-gram.l (code_start): Always initialize it when entering
13775 into yylex, as SC_EPILOGUE is activated *before* the corresponding
13776 yylex invocation. An alternative would be making it static, but
13777 then it starts with the second %%'s beginning, instead of its end.
13778
13779 2003-02-28 Paul Eggert <eggert@twinsun.com>
13780
13781 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
13782 around a UnixWare 7.1.1 porting bug reported by John Hughes in
13783 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
13784
13785 2003-02-26 Paul Eggert <eggert@twinsun.com>
13786
13787 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
13788 Remove Sequent/Pyramid discussion (nobody uses them any more).
13789 Merge VMS and MS-DOS discussion; these ports may well be dead
13790 but let's keep mentioning them for now. Put <> around email
13791 addresses. Add copyright notice.
13792
13793 2003-02-24 Paul Eggert <eggert@twinsun.com>
13794
13795 * data/glr.c (yy_reduce_print): yylineno -> yylno,
13796 to avoid collision with flex use of yylineno.
13797 Problem reported by Bruce Lilly in
13798 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
13799 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.

13803
13804 2003-02-21 Akim Demaille <akim@epita.fr>
13805
13806 * data/lalr1.cc: Use temporary variables instead of casts to
13807 change integer types.
13808 Suggested by Paul Eggert.
13809
13810 2003-02-21 Akim Demaille <akim@epita.fr>
13811
13812 * doc/bison.texinfo: Use "location" consistently to refer to @n,
13813 to avoid confusions with lalr1.cc's notion of Position.
13814 Suggested by Paul Eggert.
13815
13816 2003-02-20 Akim Demaille <akim@epita.fr>
13817
13818 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
13819 before initial_columns.
13820 (location.hh): Use consistent variable names when defining the
13821 operator<<.
13822 Use "last" so that we subtract from Positions, not from unsigned.
13823
13824 2003-02-20 Akim Demaille <akim@epita.fr>
13825
13826 * data/lalr1.cc (position.hh): New subfile, including the extended
13827 and Doxygen'ed documentation of class Position.

13833
13834 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
13835 AT_YACC_IF.
13836 Redefine AT_YYERROR_SEES_LOC_IF using it.
13837 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
13838 not defined.
13839 Don't use the location in yy::Parser::error_ and
13840 yy::Parser::print_ when not %locations.
13841 Activate more lalr1.cc tests.
13842
13843 2003-02-19 Akim Demaille <akim@epita.fr>
13844
13845 * data/lalr1.cc: When displaying a line number, be sure to make it
13846 an int.
13847
13848 2003-02-19 Akim Demaille <akim@epita.fr>
13849
13850 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
13851 Remove, useless.
13852 (YYABORT, YYACCEPT, YYERROR): New.
13853 * tests/calc.at: Renable the lalr1.cc test.
13854
13855 2003-02-19 Akim Demaille <akim@epita.fr>
13856
13857 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
13858 error recovery, mixing with/without pops and discarding of the
13859 lookahead.
13860 Exercise YYERROR.
13861 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
13862
13863 2003-02-17 Paul Eggert <eggert@twinsun.com>
13864
13865 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
13866 * tests/testsuite.at (AT_COMPILE): Use them.
13867 This fixes the testsuite problem reported by Robert Lentz in
13868 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
13869
13870 2003-02-12 Paul Eggert <eggert@twinsun.com>
13871
13872 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
13873 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
13874 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
13875 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
13876 Check for malloc failure, for consistency with yacc.c.
13877 (yytname_size): Remove, for consistency with yacc.c.
13878
13879 The bug still remains in data/lalr1.cc, as I didn't have time
13880 to fix it there.
13881
13882 2003-02-06 Akim Demaille <akim@epita.fr>
13883
13884 * configure.ac (GXX): Rename as...
13885 (CXX): this, to keep the original Autoconf semantics.
13886 Require 2.57.
13887 * data/lalr1.cc: Fix b4_copyright invocations.
13888 If YYDEBUG is not defined, don't depend upon name_ being defined.
13889 (location.hh): Include string and iostream.
13890 (Position::filename): New member.
13891 (Position::Position ()): New.
13892 (operator<< (Position)): New.
13893 (operator- (Position, int)): New.
13894 (Location::first, Location::last): Rename as...
13895 (Location::begin, Location::end): these, to mock the conventional
13896 iterator names.
13897 (operator<< (Location)): New.
13898 * tests/atlocal.in (CXX): New.
13899 * tests/testsuite.at (AT_COMPILE_CXX): New.
13900 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
13901 locations in a more synthetic way.
13902 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
13903 lalr1.cc is used.
13904 Adjust the C locations to match those from Emacs: first column is
13905 column 0.
13906 Change all the expected results.
13907 Conform to the GCS: simplify the locations when applicable.
13908 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
13909 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
13910 these CPP macros with the m4 macros new defined by...
13911 (AT_CHECK_PUSHDEFS): this, i.e.:
13912 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
13913 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
13914 New macros.
13915 (AT_CHECK_POPDEFS): Undefine them.
13916 (AT_CHECK_CALC_LALR1_CC): New.
13917 Use it for the first lalr1.cc test.
13918
13919 2003-02-04 Akim Demaille <akim@epita.fr>
13920
13921 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
13922 Location as is defined.
13923
13924 2003-02-04 Akim Demaille <akim@epita.fr>
13925
13926 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
13927 name_ being defined.
13928
13929 2003-02-03 Paul Eggert <eggert@twinsun.com>
13930
13931 * src/gram.h (start_symbol): Remove unused decl.
13932
13933 Use more-consistent naming conventions for local vars.
13934
13935 * src/derives.c (derives_compute): Change type of local var from
13936 int to rule_number.
13937 * src/gram.c (grammar_rules_partial_print): Likewise.
13938 * src/print.c (print_core): Likewise.
13939 * src/reduce.c (reduce_grammar_tables): Likewise.
13940
13941 * src/gram.c (grammar_dump): Change name of item_number *
13942 local var from r to rp.
13943 * src/nullable.c (nullable_compute): Likewise.
13944
13945 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.

13948 for symbol or symbol_number var.
13949 * src/reader.c (grammar_start_symbol_set): Likewise.
13950 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
13951 Likewise.

13954 * src/tables.c (symbol_number_to_vector_number): Likewise.
13955
13956 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
13957 char * var.
13958
13959 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
13960 var.
13961
13962 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
13963 var.
13964
13965 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
13966 Use str, not s, for char * var. Use ch, not c, for character var.
13967 Use size for size var.
13968
13969 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
13970 char * var.
13971 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for

13976 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
13977 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
13978 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
13979 param to have same name as that of enum, so that we don't use
13980 "s" to stand for a non-state.
13981
13982 2003-02-02 Akim Demaille <akim@epita.fr>
13983
13984 * src/scan-skel.l: Scan more than one inert character per yylex
13985 invocation.
13986
13987 2003-02-01 Paul Eggert <eggert@twinsun.com>
13988
13989 Version 1.875a.
13990
13991 * po/LINGUAS: Add ms.
13992
13993 2003-01-30 Akim Demaille <akim@epita.fr>
13994
13995 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
13996
13997 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
13998
13999 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
14000 of $1.
14001
14002 Changes in response to error report by S. Eken: GLR mode does not
14003 handle negative $ indices or $ indices in embedded rules correctly.
14004 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
14005
14006 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
14007 (b4_rhs_location): Ditto.
14008 (yyfill): New function to copy from stack tree into array
14009 incrementally.
14010 (yyuserAction): Modify to allow incremental move of semantic values
14011 to rhs array when in GLR mode.
14012 Define YYFILL to use in user-defined actions to fill semantic array
14013 as needed.
14014 Remove dummy use of yystack, as there is now a guaranteed use.
14015 (yydoAction): Modify to allow incremental move of semantic values
14016 to rhs array when in GLR mode.
14017 (yyresolveAction): Ditto.
14018 (yyglrShiftDefer): Update comment.
14019 (yyresolveStates): Use X == NULL for pointers, not !X.
14020 (yyglrReduce): Ditto.
14021 (yydoAction): Ditto
14022
14023 * tests/glr-regr1.at: Rename to ...
14024 * tests/glr-regression.at: Add new regression test for the problems
14025 described above (adapted from S. Eken).
14026 Update copyright notice.
14027 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
14028 * tests/Makefile.am: Ditto.
14029
14030 2003-01-28 Paul Eggert <eggert@twinsun.com>
14031
14032 * data/lalr1.cc: Do not use @output_header_name@ unless
14033 b4_defines_flag is set. This fixes two bugs reported by
14034 Tim Van Holder in
14035 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
14036 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
14037
14038 2003-01-21 Paul Eggert <eggert@twinsun.com>
14039
14040 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
14041 we don't need to worry about yyerrlab1 being reported as an
14042 "unused label" by non-GCC C compilers. The downside is that if
14043 locations are used then a couple of statements are duplicated each
14044 time YYERROR is invoked, but the upside is that the warnings
14045 should vanish.
14046 (yyerrlab1): Move code to YERROR.
14047 (yyerrlab2): Remove. Change uses back to yyerrlab1.
14048 This reverts some of the 2002-12-27 change.
14049
14050 2003-01-17 Paul Eggert <eggert@twinsun.com>
14051
14052 * src/output.c (symbol_printers_output): Fix typo that led
14053 to core dump. Problem reported by Antonio Rus in
14054 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
14055
14056 2003-01-13 Akim Demaille <akim@epita.fr>,
14057 Quoc Peyrot <chojin@lrde.epita.fr>,
14058 Robert Anisko <anisko_r@lrde.epita.fr>
14059
14060 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
14061 when the stacks contain one element, as the loop would otherwise
14062 free the last state, and then use the top state (the one we just
14063 popped). This means that the initial elements will not be freed
14064 explicitly, as is the case in yacc.c; it is not a problem, as
14065 these elements have fake values.
14066
14067 2003-01-11 Paul Eggert <eggert@twinsun.com>
14068
14069 * NEWS: %expect-violations are now just warnings, reverting
14070 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
14071 bootstrapping problem reported by Matthias Klose; see
14072 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
14073 * src/conflicts.c (conflicts_print): Likewise.
14074 * tests/conflicts.at (%expect not enough, %expect too much,
14075 %expect with reduce conflicts): Likewise.
14076 * doc/bison.texinfo (Expect Decl): Document this. Also mention
14077 that the warning is enabled if the number of conflicts changes
14078 (not necessarily increases).
14079
14080 * src/getargs.c (version): Update copyright year.
14081
14082 2003-01-09 Akim Demaille <akim@epita.fr>
14083
14084 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
14085
14086 2003-01-08 Paul Eggert <eggert@twinsun.com>
14087
14088 * Makefile.maint (WGETFLAGS):
14089 New macro, containing "-C off" to disable proxy caches.
14090 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
14091 (rel-check): Use $(WGET) instead of wget.
14092
14093 2003-01-06 Paul Eggert <eggert@twinsun.com>
14094
14095 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
14096 the GLR paper of Scott, Johnstone and Hussain.
14097
14098 2003-01-04 Paul Eggert <eggert@twinsun.com>
14099
14100 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
14101 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
14102 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
14103 (EXTRA_LIBRARIES): New var, for liby.a.
14104 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
14105 (EXTRA_SCRIPTS): New var, for yacc.
14106
14107 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
14108 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
14109 Problem reported by Nelson H. F. Beebe.
14110
14111 2003-01-03 Paul Eggert <eggert@twinsun.com>
14112
14113 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
14114 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
14115 when compiling Bison 1.875's `bitset bset = obstack_alloc
14116 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
14117
14118 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
14119 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
14120 grow to a huge size with typical invocation.
14121
14122 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
14123 Use the pattern recommended by Autoconf 2.57, except also protect
14124 against double-definition.
14125 * src/system.h: Likewise.
14126 Portability issues reported by Nelson H. F. Beebe.
14127
14128 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
14129 All uses changed. Provide a definition in both C and C++.
14130 (yytrue, yyfalse): Define even if defined (__cplusplus).
14131
14132 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
14133 Reported by Nelson H. F. Beebe.
14134
14135 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
14136
14137 2003-01-02 Paul Eggert <eggert@twinsun.com>
14138
14139 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
14140 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
14141 Bug reported by Nelson H. F. Beebe.
14142
14143 2003-01-01 Paul Eggert <eggert@twinsun.com>
14144
14145 * Version 1.875.
14146
14147 2002-12-30 Paul Eggert <eggert@twinsun.com>
14148
14149 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
14150 Moved here from...
14151 (<INITIAL>","): Here. This causes stray "," to be treated
14152 more uniformly.
14153
14154 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
14155 last brace in braced code when not in Yacc mode, for compatibility
14156 with Bison 1.35. This resurrects the 2001-12-15 patch to
14157 src/reader.c.
14158
14159 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
14160 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
14161
14162 2002-12-28 Paul Eggert <eggert@twinsun.com>
14163
14164 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
14165 that of SYM's type. This fixes Debian bug 168069, reported by
14166 Thomas Olsson.
14167
14168 2002-12-28 Paul Eggert <eggert@twinsun.com>
14169
14170 Version 1.75f.
14171
14172 Switch back to the Yacc style of conflict reports, undoing some
14173 of the 2002-07-30 change.
14174 * doc/bison.texinfo (Understanding): Use Yacc style for
14175 conflict reports. Also, use new way of locating rules.
14176 * src/conflicts.c (conflict_report):
14177 Renamed from conflict_report_yacc, removing the old
14178 'conflict_report'. Translate the entire conflict report at once,
14179 so that we don't assume that "," has the same interpretation in
14180 all languages.
14181 (conflicts_output): Use Yacc-style conflict report for each state,
14182 instead of our more-complicated style.
14183 (conflicts_print): Use Yacc-style conflict report, except print
14184 the input file name when not emulating Yacc.
14185 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
14186 Conflicted Reduction, %expect not enough, %expect too much,
14187 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
14188 * tests/existing.at (GNU Cim Grammar): Likewise.
14189 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
14190
14191 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
14192 fatal): Don't invoke fflush; it's not needed and it might even be
14193 harmful for stdout, as stdout might not be open.
14194 * src/reduce.c (reduce_print): Likewise.
14195
14196 2002-12-27 Paul Eggert <eggert@twinsun.com>
14197
14198 Fix a bug where error locations were not being recorded correctly.
14199 This problem was originally reported by Paul Hilfinger in
14200 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
14201
14202 * data/yacc.c (yyparse): New local var yylerrsp, to record the
14203 top of the location stack's error locations.
14204 (yyerrlab): Set it. When discarding a token, push its location
14205 onto yylerrsp so that we don't lose track of the error's end.
14206 (yyerrlab1): Now is only the target of YYERROR, so that we can
14207 properly record the location of the action that failed. For GCC
14208 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
14209 GCC warning about yyerrlab1 being unused if YYERROR is unused.
14210 (yyerrlab2): New label, which yyerrlab now falls through to.
14211 Compute the error's location by applying YYLLOC_DEFAULT to
14212 the locations of all the symbols that went into the error.
14213 * doc/bison.texinfo (Location Default Action): Mention that
14214 YYLLOC_DEFAULT is also invoked for syntax errors.
14215 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
14216 Error locations include the locations of all the tokens that were
14217 discarded, not just the last token.
14218
14219 2002-12-26 Paul Eggert <eggert@twinsun.com>
14220
14221 * src/files.c: Include quote.h.
14222 (compute_output_file_names): Warn if we detect conflicting
14223 outputs to the same file. This should catch the misunderstanding
14224 exemplified by Debian Bug 165349, reported by Bruce Stephens..
14225
14226 * src/conflicts.c (conflicts_print): If the user specifies
14227 "%expect N", report an error if there are any reduce/reduce
14228 conflicts. This is what the manual says should happen.
14229 This fixes Debian bug 130890, reported by Anthony DeRobertis.
14230 * tests/conflicts.at (%expect with reduce conflicts): New test.
14231
14232 Don't use m4_include on relative file names, as it doesn't work as
14233 desired if there happens to be a file with that name under ".".
14234
14235 * m4sugar/version.m4: Remove; it was included but it wasn't used.
14236 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
14237 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
14238 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
14239 * src/output.c (output_skeleton): Use full path names when
14240 specifying a file to include; don't rely on include path, as
14241 it's unreliable when the working file contains a file with
14242 that name.
14243
14244 2002-12-25 Paul Eggert <eggert@twinsun.com>
14245
14246 Remove obsolete references to bison.simple and bison.hairy.
14247 Problem mentioned by Aubin Mahe in
14248 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
14249 * data/glr.c: Comment fix.
14250 * doc/bison.1: Remove references. Also, mention "yacc".
14251
14252 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
14253 with -g option.
14254
14255 * src/parse-gram.y (declaration): Use enum "report_states" rather
14256 than its numeric value 1.
14257
14258 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
14259 opening a new one. This fixes Debian bug 165349, reported by
14260 Bruce Stephens.
14261
14262 2002-12-24 Paul Eggert <eggert@twinsun.com>
14263
14264 Version 1.75e.
14265
14266 * Makefile.maint (cvs-update): Don't assume that the shell
14267 supports $(...), as Solaris sh doesn't.
14268
14269 * src/parse-gram.y (lloc_default): Remove test for empty
14270 nonterminals at the end, since it didn't change the result.
14271
14272 2002-12-24 Paul Eggert <eggert@twinsun.com>
14273
14274 If the user does not define YYSTYPE as a macro, Bison now declares it
14275 using typedef instead of defining it as a macro. POSIX requires this.
14276 For consistency, YYLTYPE is also declared instead of defined.
14277
14278 %union directives can now have a tag before the `{', e.g., the
14279 directive `%union foo {...}' now generates the C code
14280 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
14281 The default union tag is `YYSTYPE', for compatibility with Solaris 9
14282 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
14283 instead of `yyltype'.
14284
14285 `yystype' and `yyltype' are now obsolescent macros instead of being
14286 typedefs or tags; they are no longer documented and will be
14287 withdrawn in a future release.
14288
14289 * data/glr.c (b4_location_type): Remove.
14290 (YYSTYPE): Renamed from yystype.
14291 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
14292 (struct YYLTYPE): Renamed from struct yyltype.
14293 (YYLTYPE): Renamed from yyltype.
14294 (yyltype, yystype): New (and obsolescent) macros,
14295 for backward compatibility.
14296 * data/yacc.c: Likewise.
14297
14298 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
14299 does not specify a union tag. This is for compatibility with
14300 Solaris 9 yacc.
14301
14302 * src/parse-gram.y (add_param): 2nd arg is now char * not char
14303 const *, since it is now modified by stripping surrounding { }.
14304 (current_braced_code): Remove.
14305 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
14306 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
14307 trailing " {...}". Now of type <chars>.
14308 (grammar_declaration): Adjust to bundled tokens.
14309 (code_content): Remove; stripping is now done by add_param.
14310 (print_token_value): Print contents of bundled tokens.
14311 (token_name): New function.
14312
14313 * src/reader.h (braced_code, current_braced_code): Remove.
14314 (token_name): New decl.
14315
14316 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
14317 token_type, not braced_code code_kind. All uses changed.
14318 (SC_PRE_CODE): New state, for scanning after a keyword that
14319 has (or usually has) an immediately-following braced code.
14320 (token_type): New local var, to keep track of which token type
14321 to return when scanning braced code.
14322 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
14323 <INITIAL>"%parse-param", <INITIAL>"%printer",
14324 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
14325 instead of returning a token type immediately.
14326 (<INITIAL>"{"): Set token type.
14327 (<SC_BRACED_CODE>"}"): Use it.
14328 (handle_action_dollar, handle_action_at): Now returns bool
14329 indicating success. Fail if ! current_rule; this prevents a core dump.
14330 (handle_symbol_code_dollar, handle_symbol_code_at):
14331 Remove; merge body into caller.
14332 (handle_dollar, handle_at): Complain in invalid contexts.
14333
14334 * NEWS, doc/bison.texinfo: Document the above.
14335 * NEWS: Fix years and program names in copyright notice.
14336
14337 2002-12-17 Paul Eggert <eggert@twinsun.com>
14338
14339 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
14340 Reporting, Table of Symbols): Omit mentions of %lex-param and
14341 %parse-param from the documentation for now.
14342
14343 2002-12-15 Paul Eggert <eggert@twinsun.com>
14344
14345 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
14346 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
14347 lookahead symbol, and which sets yychar in parser actions) and it
14348 disagreed with the Bison documentation. Bug
14349 reported by Andrew Walrond.
14350
14351 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
14352 as the caller now does that.
14353 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
14354 (YYEMPTY): Parenthesize right hand side, since others use it.
14355 (yyparse): Don't assume that our generated code is the only code
14356 that sets yychar.
14357
14358 2002-12-13 Paul Eggert <eggert@twinsun.com>
14359
14360 Version 1.75d.
14361
14362 POSIX requires a "yacc" command.
14363 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
14364 (MOSTLYCLEANFILES): Add yacc.
14365 (yacc): New rule.
14366 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
14367 as an alias for bison y.
14368
14369 * po/LINGUAS: Add da.
14370
14371 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
14372 problem with latest <getopt.h>.
14373 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
14374
14375 * doc/fdl.texi: Upgrade to 1.2.
14376 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
14377 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
14378 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
14379 gnulib.
14380 * config/install-sh: Sync with autotools.
14381
14382 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
14383 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
14384 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
14385 locations are requested.
14386 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
14387 locations are requested.
14388
14389 2002-12-12 Paul Eggert <eggert@twinsun.com>
14390
14391 Remove unportable casts and storage allocation tricks.
14392 While we're at it, remove almost all casts, since they
14393 usually aren't needed and are a sign of trouble.
14394
14395 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
14396
14397 * src/derives.c (derives_compute): Do not subtract NTOKENS from
14398 the pointer DSET returned by malloc; this isn't portable.
14399 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
14400 Similarly for DERIVES.
14401 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
14402 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
14403 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
14404
14405 * src/derives.c (derives_compute): Do not bother invoking
14406 int_of_rule_number, since rule numbers are integers.
14407
14408 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
14409 rather than XMALLOC (char, N).
14410
14411 * src/files.c (filename_split): Rewrite to avoid cast.
14412
14413 * src/gram.h (symbol_number_as_item_number,
14414 item_number_as_symbol_number, rule_number_as_item_number,
14415 item_number_as_rule_number):
14416 Now inline functions rather than macros, to avoid casts.
14417 * src/state.h (state_number_as_int): Likewise.
14418 * src/tables.c (state_number_to_vector_number,
14419 symbol_number_to_vector_number): Likewise.
14420
14421 * src/gram.h (int_of_rule_number): Remove; no longer used.
14422
14423 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
14424 since the resulting storage is always stored into.
14425
14426 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
14427 where it's needed.
14428
14429 * src/muscle_tab.c (muscle_m4_output):
14430 Now inline. Return bool, not int.
14431 * src/state.c (state_compare): Likewise.
14432 * src/symtab.c (symbol_check_defined,
14433 symbol_check_alias_consistency, symbol_pack, symbol_translation,
14434 hash_compare_symbol, hash_symbol):
14435 Likewise.
14436 * src/uniqstr.c (uniqstr_print): Likewise.
14437 * src/muscle_tab.c (muscle_m4_output_processor):
14438 New function, to avoid casts.
14439 * src/state.c (state_comparator, stage_hasher): Likewise.
14440 * src/symtab.c (symbol_check_defined_processor,
14441 symbol_check_alias_consistency_processor, symbol_pack_processor,
14442 symbol_translation_processor, hash_symbol_comparator,
14443 hash_symbol_hasher): Likewise.
14444 * src/uniqstr.c (uniqstr_print_processor): Likewise.
14445 * src/muscle_tab.c (muscles_m4_output):
14446 Use new functions instead of casting old functions unportably.
14447 * src/state.c (state_hash_new): Likewise.
14448 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
14449 symbols_token_translations_init):
14450 Likewise.
14451 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
14452
14453 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
14454 var instead of casting to long, to avoid casts.
14455 (prepare_states): Use MALLOC rather than alloca, so that we don't
14456 have to worry about alloca.
14457 * src/state.c (state_hash_lookup): Likewise.
14458
14459 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
14460 local var instead of casting to unsigned char, to avoid casts.
14461
14462 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
14463 STATE_ALLOC): Remove.
14464 (transitions_new, errs_new, reductions_new, state_new): Use malloc
14465 rather than calloc, and use offsetof to avoid allocating slightly
14466 too much storage.
14467 (state_new): Initialize all members.
14468
14469 * src/state.c (state_hash): Use unsigned accumulator, not signed.
14470
14471 * src/symtab.c (symbol_free): Remove; unused.
14472 (symbol_get): Remove cast in lhs of assignment.
14473 (symbols_do): Now static. Accept generic arguments, not
14474 hashing-related ones.
14475
14476 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
14477 (symbol_processor): Remove.
14478 (symbols_do): Remove decl; now static.
14479
14480 * src/system.h (alloca): Remove; decl no longer needed.
14481 (<stddef.h>): Include, for offsetof.
14482 (<inttypes.>, <stdint.h>): Include if available.
14483 (uintptr_t): New type, if system lacks it.
14484 (CALLOC, MALLOC, REALLOC): New macros.
14485 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
14486 new macros.
14487
14488 * src/tables.c (table_size): Now int, to pacify GCC.
14489 (table_grow, table_ninf_remap): Use signed table size.
14490 (save_row): Don't bother initializing locals when not needed.
14491 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
14492 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
14493
14494 * src/vcg.h: Correct misspellings.
14495
14496 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
14497
14498
14499 * src/getargs.c (getargs): Don't assume EOF == -1.
14500
14501 2002-12-09 Paul Eggert <eggert@twinsun.com>
14502
14503 Change identifier spellings to avoid collisions with names
14504 that are reserved by POSIX.
14505
14506 Don't use names ending in _t, since POSIX reserves them.
14507 For consistency, remove _e and _s endings -- they're weren't
14508 needed to remove ambiguity. All uses changed.
14509 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
14510 turn was just renamed from struniq_t.
14511 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
14512 which in turn was just renamed from struniq_processor_t.
14513 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
14514 in turn was renamed from hash_compare_struniq_t.

14527 (rule): Renamed from rule_t.
14528 (rule_filter): Renamed from rule_filter_t.
14529 * src/lalr.c (struct goto_list): Renamed from struct goto_list_s.

14531 * src/lalr.h (goto_number): Renamed from goto_number_t.
14532 * src/location.h (location): Renamed from location_t.
14533 * src/muscle_tab.c (muscle_entry): Renamed from muscle_entry_t,

14537 (rule_list): Renamed from rule_list_t.
14538 * src/print_graph.c (static_graph): Renamed from graph.

14543 (relation): Renamed from relation_t.
14544 * src/state.h (state_number): Renamed from state_number_t.
14545 (struct state): Renamed from struct state_s.
14546 (state): Renamed from state_t.
14547 (transitions): Renamed from transitions_t. Unused (and
14548 misspelled) transtion_s tag removed.
14549 (errs): Renamed from errs_t. Unused errs_s tag removed.
14550 (reductions): Renamed from reductions_t. Unused tag
14551 reductions_s removed.
14552 * src/symlist.h (symbol_list): Renamed from symbol_list_t.

14583 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
14584 value_t_as_yystype -> value_as_yystype.
14585
14586 Don't include <errno.h> in the mainstream code, since it
14587 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
14588 * lib/get-errno.c, lib/get-errno.h: New files.
14589 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
14590 get-errno.c.
14591 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
14592 * src/output.c (output_skeleton): Likewise.
14593 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
14594 instead of errno.
14595 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):
14596 Likewise.
14597 (handle_action_dollar, handle_action_at): Likewise.
14598 * src/system.h: Do not include <errno.h>.
14599 (TAB_EXT): Renamed from EXT_TAB.
14600 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
14601
14602 Avoid str[a-z]*, since <string.h> reserves that name space.
14603 Change all instances of "struniq" in names to "uniqstr", and
14604 likewise for "STRUNIQ" and "UNIQSTR".
14605 * src/uniqstr.c: Renamed from src/struniq.c.
14606 * src/uniqstr.h: Renamed from src/struniq.h.
14607 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

14618 (N_EXPAND): Renamed from N_STRETCH.
14619
14620 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
14621 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
14622 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

14630 (ACTION_MAX): Remove; unused.
14631 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
14632 Unnecessary casts removed from above defines.
14633
14634
14635 Fix misspelling in names.

14637 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
14638 G_NODE_ALIGNEMENT.
14639
14640
14641 * lib/timevar.c (timevar_report): Renamed from time_report,
14642 for consistency with other names.
14643 * lib/timevar.h (timevar_report): New decl.
14644 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
14645
14646
14647 Sort include-file uses.
14648
14649 Reorder all include files under src to be in the order "system.h".
14650 then the ../lib include files in angle brackets (alphabetized),
14651 then the . include files in double-quotes (alphabetized). Fix
14652 dependency breakages encountered in this process, as follows:
14653 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
14654 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
14655 * src/state.h: Include "symtab.h".
14656
14657 2002-12-08 Paul Eggert <eggert@twinsun.com>
14658
14659 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
14660 since this causes problems when __file__ contains character
14661 sequences like "@" that are treated specially by src/scan-skel.l.
14662 Instead, just use the file's basename. This fixes the bug
14663 reported by Martin Mokrejs in
14664 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
14665
14666 2002-12-06 Paul Eggert <eggert@twinsun.com>
14667
14668 Add support for rules that do not have trailing semicolons, as
14669 POSIX requires. Improve the quality of locations in Bison
14670 diagnostics.
14671
14672 * src/location.c: Include <quotearg.h>.
14673 (empty_location): Now const.
14674 (location_print): New function. Follow the recommendation of the
14675 GNU Coding Standards for locations that span file boundaries.
14676 * src/location.h: Do not include <quotearg.h>; no longer needed.
14677 (boundary): New type.
14678 (location_t): Use it. This allows locations to span file boundaries.
14679 All member uses changed: file -> start.file or end.file (as needed),
14680 first_line -> start.line, first_column -> start.column,
14681 last_line -> end.line, last_column -> end.column.
14682 (equal_boundaries): New function.
14683 (LOCATION_RESET, LOCATION_STEP): Remove.
14684 (LOCATION_PRINT): Remove. All callers changed to use location_print.
14685 (empty_location): Now const.
14686 (location_print): New decl.
14687 * src/parse-gram.y (lloc_default): New function, which handles
14688 empty locations more accurately.
14689 (YYLLOC_DEFAULT): Use it.
14690 (%token COLON): Remove.
14691 (%token ID_COLON): New token.
14692 (rules): Use it.
14693 (declarations, rules): Remove trailing semicolon.
14694 (declaration, rules_or_grammar_declaration):
14695 Allow empty (";") declaration.
14696 (symbol_def): Remove empty actions; no longer needed.
14697 (rules_or_grammar_declaration): Remove trailing semicolon.
14698 (semi_colon.opt): Remove.
14699 * src/reader.h: Include location.h.
14700 (scanner_cursor): New decl.
14701 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
14702 rolling our own.
14703 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
14704 of *loc.
14705 (STEP): Remove. No longer needed, now that adjust_location does
14706 the work. All uses removed.
14707 (scanner_cursor): New var.
14708 (adjust_location): Renamed from extend_location. It now sets
14709 *loc and adjusts the scanner cursor. All uses changed.
14710 Don't bother testing for CR.
14711 (handle_syncline): Remove location arg; now updates scanner cursor.
14712 All callers changed.
14713 (unexpected_end_of_file): Now accepts start boundary of token or
14714 comment, not location. All callers changed. Update scanner cursor,
14715 not the location.
14716 (SC_AFTER_IDENTIFIER): New state.
14717 (context_state): Renamed from c_context. All uses changed.
14718 (id_loc, code_start, token_start): New local vars.
14719 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
14720 processing of Yacc white space and equivalents here.
14721 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
14722 instead of returning ID immediately, since we need to search for
14723 a subsequent colon.
14724 (<INITIAL>"'", "\""): Save token_start.
14725 (<INITIAL>"%{", "{", "%%"): Save code_start.
14726 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
14727 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
14728 BEGIN context_state at end, not INITIAL.
14729 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
14730 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
14731 Return correct token start.
14732 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
14733 the start of a character, string or multiline comment is found.
14734 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
14735 Reduction): Adjust reported locations to match the more-precise
14736 results now expected.
14737 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
14738 * tests/reduce.at (Useless Rules, Reduced Automaton,
14739 Underivable Rules): Likewise.
14740 * tests/regression.at (Invalid inputs): No longer `expecting ";"
14741 or "|"' now that so many other tokens are allowed by the new grammar.
14742
14743 * src/complain.h (current_file): Remove duplicate decl;
14744 current_file is now owned by files.h.
14745 * src/complain.c, src/scan-gram.l: Include files.h.
14746
14747 2002-12-06 Paul Eggert <eggert@twinsun.com>
14748
14749 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
14750 promotes to int; it might be unsigned int.
14751 * data/yacc.c (yy_reduce_print): Likewise.
14752
14753 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
14754 be #defined in the prologue, not in the Bison declarations.
14755 This fixes Debian Bug 102878, reported by Shaul Karl.
14756
14757 2002-12-02 Paul Eggert <eggert@twinsun.com>
14758
14759 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
14760 * lib/strtoul.c: New file, from gnulib.
14761 This fixes a porting bug reported by Peter Klein in
14762 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
14763
14764 2002-11-30 Paul Eggert <eggert@twinsun.com>
14765
14766 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
14767 and put only a forward declaration in the prologue. This is for
14768 consistency with the other scanner helper functions.
14769
14770 Type clashes now generate warnings, not errors, since it
14771 appears that POSIX may allow some grammars with type clashes.
14772 * src/reader.c (grammar_current_rule_check): Warn about
14773 type clashes instead of complaining.
14774 * tests/input.at (Type Clashes): Expect warnings, not complaints.
14775
14776 Add Yacc library, since POSIX requires it.
14777 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
14778 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
14779 * lib/main.c, lib/yyerror.c: New files.
14780
14781 gram_error can be static; it need not be extern.
14782 * src/reader.h (gram_error): Remove decl.
14783 * src/parse-gram.y (gram_error): Now static. Add static decl.
14784 (print_token_value): Omit parameter names from forward decl,
14785 for consistency.
14786
14787 2002-11-29 Paul Eggert <eggert@twinsun.com>
14788
14789 * doc/bison.texinfo: Emphasize that yylex and yyerror must
14790 be declared before being used. E.g., one should typically
14791 declare them in the prologue. Use GNU coding style in examples.
14792 Put "const" consistently after the type it modifies. Mention
14793 that C99 supports "inline". Mention that yyerror traditionally
14794 returns "int".
14795
14796 %parse-param and %lex-param now take just one argument, the
14797 declaration; the argument name is deduced from the declaration.
14798
14799 * doc/bison.texinfo (Parser Function, Pure Calling, Error
14800 Reporting, Table of Symbols): Document this.
14801 * src/parse-gram.y (add_param): New function.
14802 (COMMA): Remove.
14803 (declaration): Implement new rule for %parse-param and %lex-param.
14804 * src/scan-gram.l: "," now elicits a warning, rather than being
14805 a token; this is more compatible with byacc.
14806 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
14807
14808 2002-11-27 Paul Eggert <eggert@twinsun.com>
14809
14810 Rename identifiers to avoid real and potential collisions.
14811
14812 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
14813 to avoid collision with lex macro described by Bruce Lilly in
14814 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
14815 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
14816 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
14817 * src/parse-gram.y (print_token_value): Renamed from yyprint.
14818 All uses changed.
14819 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
14820 The name "yycontrol" violates the name space rules, and this stuff
14821 wasn't being used anyway.
14822 (input): Remove action; this stuff wasn't being used.
14823 (gram_error): Rename local variable yylloc -> loc.
14824 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
14825 (YY_DECL): Don't use "yy" at start of local variables.
14826 All uses changed, e.g., yylloc -> loc.
14827 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
14828 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
14829 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
14830 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
14831
14832 * src/parse-gram.y (gram_error): loc is now const *.
14833 * src/reader.h (gram_error): Likewise.
14834
14835 2002-11-24 Paul Eggert <eggert@twinsun.com>
14836
14837 Version 1.75c.
14838
14839 * tests/actions.at (Actions after errors): Use an output format
14840 more similar to that of the Printers and Destructors test.
14841 Test the position of the ';' token too.
14842 (Printers and Destructors): Likewise.
14843 (Printers and Destructors: %glr-parser): Remove for now, to avoid
14844 unnecessarily alarming people when the test fails.
14845
14846 * data/yacc.c (yyerrlab1): Move this label down, so that the
14847 parser does not discard the lookahead token if the user code
14848 invokes YYERROR. This change is required for POSIX conformance.
14849
14850 * lib/error.c: Sync with gnulib.
14851
14852 2002-11-22 Paul Eggert <eggert@twinsun.com>
14853
14854 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
14855 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
14856 * lib/xmalloc.c: Likewise.
14857
14858 2002-11-20 Paul Eggert <eggert@twinsun.com>
14859
14860 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
14861
14862 2002-11-20 Paul Eggert <eggert@twinsun.com>
14863
14864 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
14865 should use `if (! x) abort ();' rather than `assert (x);', and
14866 anyway it's one less thing to worry about configuring.
14867
14868 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
14869 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
14870 and replace all instances of assert with abort.
14871 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
14872 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
14873
14874 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
14875 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
14876 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
14877 hash_find_entry, hash_rehash, hash_insert): Likewise.
14878 * src/conflicts.c (resolve_sr_conflict): Likewise.
14879 * src/lalr.c (set_goto_map, map_goto): Likewise.
14880 * src/nullable.c (nullable_compute): Likewise.
14881 * src/output.c (prepare_rules, token_definitions_output): Likewise.
14882 * src/reader.c (packgram, reader): Likewise.
14883 * src/state.c (state_new, state_free, state_transitions_set,
14884 state_reduction_find): Likewise.
14885 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
14886 symbol_pack): Likewise.
14887 * src/tables.c (conflict_row, pack_vector): Likewise.
14888 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
14889 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
14890 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
14891 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
14892
14893 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
14894 (ARGMATCH_CONSTRAINT): New macro.
14895 (ARGMATCH_ASSERT): Use it.
14896
14897 * src/system.h (verify): New macro.
14898 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
14899 rather than assert.
14900 * src/tables.c (tables_generate): Likewise.
14901
14902 * src/struniq.c (struniq_assert): Now returns void, and aborts
14903 if the assertion is false.
14904 (struniq_assert_p): Remove.
14905 * src/struniq.h: Likewise.
14906
14907 2002-11-18 Paul Eggert <eggert@twinsun.com>
14908
14909 * data/glr.c (yygetLRActions): Replace `yyindex' with
14910 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
14911 This fixes the regression with Sun ONE Studio 7 cc that I reported in
14912 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
14913
14914 2002-11-18 Akim Demaille <akim@epita.fr>
14915
14916 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
14917 space.
14918 From Tim Van Holder.
14919
14920 2002-11-17 Paul Eggert <eggert@twinsun.com>
14921
14922 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
14923 to "SyntaxError" for consistency with my 2002-11-15 change.
14924
14925 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
14926 not define to {}, since this breaks the common use of `YYDPRINTF
14927 ((...));' if a single statement is desired (e.g. before `else').
14928 Work around GCC warnings by surrounding corresponding calls with
14929 {} if needed.
14930 (yyhasResolvedValue): Remove unused function.
14931 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
14932 loop body.
14933 (yyreportSyntaxError): Renamed from yyreportParseError.
14934 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
14935 All uses changed.
14936 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
14937 extern when possible. Remove unused initializations.
14938
14939 2002-11-16 Akim Demaille <akim@epita.fr>
14940
14941 Augment the similarity between GLR and LALR traces.
14942
14943 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
14944 (YY_REDUCE_PRINT): New.
14945 (yyparse): Use them.
14946 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
14947 YYDPRINT here.
14948 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
14949 state reached after the reduction/recovery, since...
14950 (yyparse, yyprocessOneStack): Report the state we are entering in.
14951
14952 2002-11-16 Akim Demaille <akim@epita.fr>
14953
14954 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
14955 Add support for --trace=skeleton.
14956 * src/scan-skel.l: %option debug.
14957 Scan strings of non-@ or \n instead of character by character.
14958 (scan_skel): Handle trace_skeleton.
14959 (QPUTS): New.
14960 (@output_parser_name@, @output_header_name@): ``Restore'' their
14961 support (used to be M4 macros).
14962 * data/yacc.c: Quote larger chunks, a la glr.c.
14963 * data/lalr1.cc: Likewise.
14964 The header guards are no longer available, so use some other
14965 string than `YYLSP_NEEDED'.
14966
14967 2002-11-16 Akim Demaille <akim@epita.fr>
14968
14969 Make the ``Printers and Destructors'' test more verbose, taking
14970 `yacc.c''s behavior as (possibly wrong) reference.
14971
14972 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
14973 instead of fprint on stdout.
14974 Set and report the last_line of the symbols.
14975 Consistently display values and locations.
14976
14977 2002-11-16 Paul Eggert <eggert@twinsun.com>
14978
14979 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
14980
14981 2002-11-15 Paul Eggert <eggert@twinsun.com>
14982
14983 * tests/actions.at (Actions after errors): New test case.
14984
14985 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
14986 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
14987 tests/action.at, tests/calc.at, tests/conflicts.at,
14988 tests/cxx-type.at, tests/regression.at:
14989 "parse error" -> "syntax error" for POSIX compatibility.
14990 "parsing stack overflow..." -> "parser stack overflow" so
14991 that code matches Bison documentation.
14992
14993 2002-11-15 Akim Demaille <akim@epita.fr>
14994
14995 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
14996 take two BRACED_CODE, not two string_content.
14997 Free the scanner's obstack when we are done.
14998 (code_content): New.
14999 * tests/calc.at: Adjust.
15000 * doc/bison.texinfo: Adjust.
15001 Also, make sure to include the `,' for these declarations.
15002
15003 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
15004
15005 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
15006 definition; avoids potential autoreconf problems.
15007
15008 2002-11-15 Akim Demaille <akim@epita.fr>
15009
15010 Always check the value returned by yyparse.
15011
15012 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
15013 returned by yyparse.
15014 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
15015 Adjust calls.
15016 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
15017 returned by yyparse.
15018
15019 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15020
15021 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
15022 on input.at test.
15023
15024 2002-11-14 Paul Eggert <eggert@twinsun.com>
15025
15026 * src/output.c (output_skeleton): Call xfopen instead of
15027 duplicating xfopen's body.
15028
15029 Fix bugs reported by Nelson H. F. Beebe in
15030 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
15031
15032 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
15033 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
15034 Group compiler. Instead, use "$CC -E bar.c". Include the .h
15035 file twice in the grammar, as an extra check.
15036
15037 * tests/input.at (Torturing the Scanner): Surround the
15038 backslash-newline tests with "#if 0", to make it less likely that
15039 we'll run into compiler bugs. Bring back solitary \ inside
15040 comment, but add a closing comment to work around HP C bug. Don't
15041 test backslash-newline in C character constant.
15042
15043 2002-11-14 Akim Demaille <akim@epita.fr>
15044
15045 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
15046 status of the compiler.
15047 Calling `exit 1' is no longer needed.
15048 Reported by Nelson H. F. Beebe.
15049
15050 2002-11-14 Akim Demaille <akim@epita.fr>
15051
15052 * tests/atlocal.in (CPPFLAGS): We have config.h.
15053 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
15054 New.
15055 * tests/actions.at, tests/calc.at, tests/conflicts.at,
15056 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
15057 * tests/regression.at, tests/torture.at: Use them for all the
15058 grammars that are to be compiled.
15059 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
15060 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
15061 * doc/bison.texinfo (GLR Parsers): Document `inline'.
15062
15063 2002-11-14 Akim Demaille <akim@epita.fr>
15064
15065 * doc/bison.texinfo: Various formatting changes (alignments in
15066 samples, additional @group/@end group, GCS in samples.
15067 Use @deffn instead of simple @table to define the directives,
15068 macros, variables etc.
15069
15070 2002-11-13 Paul Eggert <eggert@twinsun.com>
15071
15072 Fix some bugs reported by Albert Chin-A-Young in
15073 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
15074
15075 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
15076 -o c"; the HP C compiler chatters during compilation.
15077 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
15078 * tests/headers.at (export YYLTYPE): Likewise.
15079
15080 * tests/input.at (Torturing the Scanner): Remove lines containing
15081 solitary backslashes, as they tickle a bug in the HP C compiler.
15082
15083 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
15084 comments, since they're not portable. Use GNU coding style.
15085
15086 2002-11-13 Akim Demaille <akim@epita.fr>
15087
15088 * data/yacc.c: Leave bigger chunks of quoted text.
15089 (YYDSYMPRINTF): New.
15090 Use it to report symbol activities.

15092 Use it.
15093
15094 2002-11-12 Paul Eggert <eggert@twinsun.com>
15095
15096 Version 1.75b.
15097
15098 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
15099 (yyglrReduce): Return yyok, not 0.
15100 This should avoid the enumerated-type warnings reported
15101 by Nelson H. F. Beebe in
15102 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
15103
15104 * lib/bbitset.h (BITSET_INLINE): Remove.
15105 * lib/bitset.h [! BITSET_INLINE]: Remove.
15106 (bitset_set, bitset_reset, bitset_test): Rename local vars
15107 to avoid shadowing warnings by GCC.
15108
15109 * data/glr.c (inline): Remove #define. It's the user's
15110 responsibility to #define it away, just like 'const'.
15111 This fixes one of the bugs reported by Nelson H. F. Beebe in
15112 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
15113
15114 * Makefile.maint (po-check): Scan .l and .y files instead of the
15115 .c and the .h files that they generate. This fixes the bug
15116 reported by Tim Van Holder in:
15117 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
15118 Look for N_ as well as for _. Try to avoid matching #define for
15119 N_ and _.
15120 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
15121 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
15122 * src/scan-gram.l: Revamp regular expressions so that " and '
15123 do not confuse xgettext.
15124
15125 * src/struniq.h (struniq_new): Do not declare the return type
15126 to be 'const'; this violates the C standard.
15127 * src/struniq.c (struniq_new): Likewise.
15128
15129 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
15130
15131 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
15132 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
15133 linker.
15134
15135 2002-11-12 Akim Demaille <akim@epita.fr>
15136
15137 * Makefile.maint: Sync with Autoconf:
15138 (local_updates): New.
15139
15140 2002-11-12 Akim Demaille <akim@epita.fr>
15141
15142 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
15143
15144 2002-11-12 Akim Demaille <akim@epita.fr>
15145
15146 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
15147 locations.
15148
15149 2002-11-12 Akim Demaille <akim@epita.fr>
15150
15151 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
15152 not yyvalue.
15153
15154 2002-11-12 Akim Demaille <akim@epita.fr>
15155
15156 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
15157 Use it to test the GLR parser.
15158
15159 2002-11-12 Akim Demaille <akim@epita.fr>
15160
15161 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
15162 defines it.
15163 * data/glr.c (yystos): New.
15164 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
15165 (YYDSYMPRINT): New.
15166 (yyval): Don't define it, it is handled via M4.
15167 (yyrecoverParseError): Free verbosely the discarded symbols.
15168 * data/yacc.c (yysymprint): Remove, rather...
15169 (b4_yysymprint_generate): invoke.
15170 * data/c.m4 (b4_yysymprint_generate): New.
15171 Accept pointers as arguments, as opposed to the version from
15172 yacc.c.
15173 (b4_yydestruct_generate): Likewise.
15174 * tests/cations.at (Printers and Destructors): Use Bison directives
15175 instead of CPP macros.
15176 Don't rely on internal details.
15177
15178 2002-11-12 Akim Demaille <akim@epita.fr>
15179
15180 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
15181 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
15182 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
15183 it against YYEMPTY and so forth), work on yytoken (i.e., set
15184 it to YYEMPTY etc.).
15185 (yydestruct): Replace with a b4_yydestruct_generate invocation.
15186 (b4_symbol_actions): Remove.
15187 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
15188 for 0, end-of-input.
15189
15190 2002-11-12 Akim Demaille <akim@epita.fr>
15191
15192 * doc/bison.texinfo (Destructor Decl): New.
15193
15194 2002-11-12 Akim Demaille <akim@epita.fr>
15195
15196 * src/tables.c (tables_generate): Use free for pointers that
15197 cannot be NULL, not XFREE.
15198 (pack_vector): Use assert, not fatal, for bound violations.
15199 * src/state.c (state_new): Likewise.
15200 * src/reader.c (reader): Likewise.
15201 * src/lalr.c (set_goto_map): Likewise.
15202 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
15203 the file name.
15204
15205 2002-11-12 Akim Demaille <akim@epita.fr>
15206
15207 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
15208 Restore.
15209 * src/scan-gram.l (last_string): Is global to the file, not to
15210 yylex.
15211 * src/parse-gram.y (input): Don't append the epilogue here,
15212 (epilogue.opt): do it here, and free the scanner's obstack.
15213 * src/reader.c (epilogue_set): Rename as...
15214 (epilogue_augment): this.
15215 * data/c.m4 (b4_epilogue): Defaults to empty.
15216
15217 2002-11-12 Akim Demaille <akim@epita.fr>
15218

15226
15227 * src/struniq.h, src/struniq.c (struniq_t): Is const.
15228 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
15229
15230 Use struniq for symbols.
15231
15232 * src/symtab.h (symbol_t): The tag member is a struniq.
15233 (symbol_type_set): Adjust.

15273 2002-11-11 Paul Eggert <eggert@twinsun.com>
15274
15275 Revamp to fix many (but not all) of the C- and M4-related quoting
15276 problems. Among other things, this fixes the Bison bug reported
15277 by Jan Hubicka when processing the Bash grammar; see:
15278 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
15279
15280 Use new @ escapes consistently. Represent brackets with @{ and @}
15281 rather than @<:@ and @:>@, since this works a bit better with dumb
15282 editors like vi. Represent @ with @@, since @ is now consistently
15283 an escape. Use @oline@ and @ofile@ rather than __oline__ and
15284 __ofile__, to avoid unexpected expansions. Similarly, use @output
15285 rather than #output.
15286
15287 * data/c.m4 (b4_copyright): Omit file name from comment, since
15288 the file name could contain "*/".
15289 (b4_synclines_flag): Don't quote the 2nd argument; it should already
15290 be quoted. All uses changed.
15291
15292 * data/glr.c: Use new @ escapes consistently.
15293 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
15294 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
15295 Remove, since they couldn't handle arbitrary characters in file
15296 names.
15297 * data/lalr1.cc: Likewise.
15298 * data/yacc.c: Likewise.
15299
15300 * src/files.c (output_infix): Remove; all uses removed.
15301 * src/files.h: Likewise.
15302
15303 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
15304 mishandled funny characters in file names, and anyway it isn't
15305 needed any more.
15306 * data/yacc.c: Likewise.
15307 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
15308
15309 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
15310 * data/yacc.c: Likewise.
15311
15312 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
15313 strings now.
15314 (muscle_init): Quote filename as a C string.
15315 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
15316 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
15317 * src/output.c (escaped_file_name_output): New function.
15318 (prepare_symbols): Quote tokens for M4.
15319 (prepare): Don't insert output_infix, output_prefix,
15320 output_parser_name, output_header_name; this is now down by scan-skel.
15321 Insert skeleton as a C string.
15322
15323 * src/output.c (user_actions_output, symbol_destructors_output,
15324 symbol_printers_output): Quote filenames for C and M4.
15325 * src/reader.c (prologue_augment, epilogue_set): Likewise.
15326
15327 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
15328 escapes other than \\ and \'; this simplifies the code.
15329 (<SC_STRING>): Likewise, for \\ and \".
15330 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
15331 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
15332 Use new escapes @{ and @} for [ and ].
15333
15334 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
15335 them with auto vars.
15336 Switch to new escape scheme, where @ is the escape character uniformly.
15337 Abort if a stray escape character is found. Avoid unbounded input
15338 buffer when parsing non-escaped text.
15339
15340 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
15341 __oline__, #output, $@, and @{ do not have unintended meanings.
15342
15343 2002-11-09 Paul Eggert <eggert@twinsun.com>
15344
15345 Fix the test failure due to GCC warnings described in
15346 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
15347 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
15348 evaluate to 0 if it's impossible for NINF to be in the respective
15349 table.
15350 (yygetLRActions, yyrecoverParseError): Use them.
15351
15352 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
15353 counted in the token inserted at end of file. Now takes
15354 location_t *, not location_t, so that the location can be
15355 adjusted. All uses changed.
15356
15357 * tests/regression.at (Invalid inputs): Adjust wording in
15358 diagnostic to match the new behavior.
15359
15360 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
15361 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
15362 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
15363 abort ();'. This reduces the runtime of the "Many lookaheads"
15364 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
15365 GCC 3.2.
15366
15367 2002-11-07 Paul Eggert <eggert@twinsun.com>
15368
15369 * src/parse-gram.y (CHARACTER): Remove unused token.
15370 All uses removed.
15371
15372 * src/scan-gram.l: Remove stack option. We no longer use the
15373 stack, since the stack was never deeper than 1; instead, use the
15374 new auto var c_context to record the stacked value.
15375
15376 Remove nounput option. At an unexpected end of file, we now unput
15377 the minimal input necessary to end cleanly; this simplifies the
15378 code.
15379
15380 Avoid unbounded token sizes where this is easy.
15381
15382 (unexpected_end_of_file): New function.
15383 Use it to systematize the error message on unexpected EOF.
15384 (last-string): Now auto, not static.
15385 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
15386 (scanner_last_string_free): Remove; not used.
15387 (percent_percent_count): Move decl to just before use.
15388 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
15389 not the (never otherwised-used) CHARACTER.
15390
15391 2002-11-07 Akim Demaille <akim@epita.fr>
15392
15393 Let yyerror always receive the msg as last argument, so that
15394 yyerror can be variadic.
15395
15396 * data/yacc.c (b4_yyerror_args): New.
15397 Use it when calling yyerror.
15398 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
15399 Use it when calling yyerror.
15400 * doc/bison.texinfo (Error Reporting): Adjust.
15401 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
15402 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
15403
15404 2002-11-06 Akim Demaille <akim@epita.fr>
15405
15406 #line should have quoted strings.
15407 Ideally, this should be done by m4_quotearg.
15408
15409 * src/scan-skel.l: Include quotearg.h.
15410 Quote __ofile__.
15411 * src/output.c (symbol_printers_output)
15412 (symbol_destructors_output): Quote the file name.
15413
15414 2002-11-06 Akim Demaille <akim@epita.fr>
15415
15416 * tests/regression.at (Invalid inputs): Adjust to the recent
15417 messages.
15418
15419 2002-11-06 Akim Demaille <akim@epita.fr>
15420
15421 Restore --no-lines.
15422 Reported by Jim Kent.
15423
15424 * data/c.m4 (b4_syncline): New.
15425 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
15426 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
15427 * src/output.c (user_actions_output): Likewise.
15428 (prepare): Define 'b4_synclines_flag'.
15429 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
15430
15431 2002-11-06 Akim Demaille <akim@epita.fr>
15432
15433 * src/main.c (main): Free `infile'.
15434 * src/scan-gram.l (handle_syncline): New.
15435 Recognize `#line'.
15436 * src/output.c (user_actions_output, symbol_destructors_output)
15437 (symbol_printers_output): Use the location's file name, not
15438 infile.
15439 * src/reader.c (prologue_augment, epilogue_set): Likewise.
15440
15441 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15442
15443 * src/tables.c (matching_state): Don't allow states to match if
15444 either has GLR conflict entries.
15445
15446 2002-11-05 Paul Eggert <eggert@twinsun.com>
15447
15448 * src/scan-gram.l: Use more accurate diagnostics, e.g.
15449 "integer out of range" rather than "invalid value".
15450 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
15451 accordingly.
15452
15453 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
15454 Also, remove one static variable in the scanner.
15455
15456 * src/scan-gram.l (braces_level): Now auto, not static.
15457 Initialize to zero if the compiler is being picky.
15458 (INITIAL): Clear braces_level instead of incrementing it.
15459 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
15460 as POSIX 1003.1-2001 requires.
15461 * src/system.h (IF_LINT): New macro, taken from coreutils.
15462 * configure.ac: Define "lint" if --enable-gcc-warnings.
15463
15464 2002-11-05 Akim Demaille <akim@epita.fr>
15465
15466 * src/scan-gram.l: When it starts with `%', complain about the
15467 whole directive, not just that `invalid character: %'.
15468
15469 2002-11-04 Akim Demaille <akim@epita.fr>
15470
15471 * Makefile.maint: Update from Autoconf.
15472 (update, cvs-update, po-update, do-po-update): New.
15473
15474 2002-11-04 Akim Demaille <akim@epita.fr>
15475
15476 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
15477 and yyerror.
15478 Have yyerror `use' its arguments.
15479 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
15480 returns true when location & yacc & pure & parse-param.
15481 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
15482
15483 2002-11-04 Akim Demaille <akim@epita.fr>
15484
15485 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
15486 clashes.
15487 * src/scan-gram.l: Use [\'] instead of ['] to pacify
15488 font-lock-mode.
15489 Use complain_at.
15490 Use quote, not quote_n since LOCATION_PRINT no longer uses the
15491 slot 0.
15492
15493 2002-11-03 Paul Eggert <eggert@twinsun.com>
15494
15495 * src/reader.c (get_merge_function, grammar_current_rule_check):
15496 Use consistent diagnostics for reporting type name clashes.
15497 Quote the types with <>, for consistency with Yacc.
15498 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
15499
15500 2002-11-03 Akim Demaille <akim@epita.fr>
15501
15502 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
15503 New.
15504 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
15505 (b4_parse_param): Remove.
15506 Use b4_identification.
15507 Propagate b4_pure_args where needed to pass them to yyerror.
15508 * data/glr.m4 (b4_parse_param): Remove.
15509 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
15510 (b4_lpure_formals): New.
15511 Use b4_identification.
15512 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
15513 b4_user_formals and b4_user_args.
15514 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
15515 (yyreportAmbiguity): When using a pure parser, also need
15516 the location, and the parse-params.
15517 Adjust callers.
15518 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
15519 When using a pure parser, also need the parse-params.
15520 Adjust callers.
15521 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
15522 (%pure-parser + %parse-param) LALR and GLR parsers.
15523 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
15524 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
15525 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
15526 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

15529 * doc/bison.texinfo: Untabify the whole file.
15530 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
15531 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
15532 (Error Reporting): Adjust to these new directives.
15533 Document %error-verbose, deprecate YYERROR_VERBOSE.
15534
15535 2002-11-03 Akim Demaille <akim@epita.fr>
15536
15537 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
15538 AT_CHECK_CALC_GLR invocations to use % directives, instead of
15539 command line options.
15540 * tests/cxx-type.at: Formatting changes.
15541
15542 2002-11-03 Paul Eggert <eggert@twinsun.com>
15543
15544 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
15545 to count columns correctly, and to check for invalid inputs.
15546
15547 Use mbsnwidth to count columns correctly. Account for tabs, too.
15548 Include mbswidth.h.
15549 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
15550 (extend_location): New function.
15551 (YY_LINES): Remove.
15552
15553 Handle CRLF in C code rather than in Lex code.
15554 (YY_INPUT): New macro.
15555 (no_cr_read): New function.
15556
15557 Scan UCNs, even though we don't fully handle them yet.
15558 (convert_ucn_to_byte): New function.
15559
15560 Handle backslash-newline correctly in C code.
15561 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
15562 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
15563 all uses changed.
15564 (tag, splice): New EREs. Do not allow NUL or newline in tags.
15565 Use {splice} wherever C allows backslash-newline.
15566 YY_STEP after space, newline, vertical-tab.
15567 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
15568
15569 (letter, id): Don't assume ASCII; e.g., spell out a-z.
15570
15571 ({int}, handle_action_dollar, handle_action_at): Check for integer
15572 overflow.
15573
15574 (YY_STEP): Omit trailing semicolon, so that it's more like C.
15575
15576 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
15577 as well as \000. Check for UCHAR_MAX, not 255.
15578 Allow \x with an arbitrary positive number of digits, as in C.
15579 Check for overflow here.
15580 Allow \? and UCNs, for compatibility with C.
15581
15582 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
15583 with quote slot used by complain_at.
15584
15585 * tests/input.at: Add tests for backslash-newline, m4 quotes
15586 in symbols, long literals, and funny escapes in strings.
15587
15588 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
15589 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
15590 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
15591 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
15592 * m4/mbswidth.m4: New file, from GNU coreutils.
15593
15594 * doc/bison.texinfo (Grammar Outline): Document // comments.
15595 (Symbols): Document that trigraphs have no special meaning in Bison,
15596 nor is backslash-newline allowed.
15597 (Actions): Document that trigraphs have no special meaning.
15598
15599 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
15600 no longer used.
15601
15602 2002-11-02 Paul Eggert <eggert@twinsun.com>
15603
15604 * src/reader.c: Don't include quote.h; not needed.
15605 (get_merge_function): Reword warning to be consistent with
15606 type clash diagnostic in grammar_current_rule_check.
15607
15608 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
15609 bug in trigraph handling.
15610
15611 * src/output.c (prepare_symbols): When printing token names,
15612 escape "[" as "@<:@" and likewise for "]".
15613
15614 * src/system.h (errno): Remove declaration, as we are now
15615 assuming C89 or better, and C89 guarantees errno.
15616
15617 2002-10-30 Paul Eggert <eggert@twinsun.com>
15618
15619 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
15620 Check for close failures.
15621 * src/files.h (xfclose): Return void, not int, since it always
15622 returned zero.
15623 * src/files.c (xfclose): Likewise. Report I/O error if ferror
15624 indicates one.
15625 * src/output.c (output_skeleton): Use xfclose rather than fclose
15626 and ferror. xfclose now checks ferror.
15627
15628 * data/glr.c (YYLEFTMOST_STATE): Remove.
15629 (yyreportTree): Use a stack-based leftmost state. This avoids
15630 our continuing battles with bogus warnings about initializers.
15631
15632 2002-10-30 Akim Demaille <akim@epita.fr>
15633
15634 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
15635 #if.
15636
15637 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15638
15639 * tests/glr-regr1.at: New test for reported regressions.
15640 * tests/testsuite.at: Add glr-regr1.at test.
15641 * tests/Makefile.am: Add glr-regr1.at test.
15642
15643 2002-10-24 Paul Eggert <eggert@twinsun.com>
15644
15645 Version 1.75a.
15646
15647 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
15648 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
15649 we use malloc. Don't assume 'A' through 'Z' are contiguous.
15650 Don't assume strdup exists; POSIX says its an XSI extension.
15651 Check for buffer overflow on input.
15652
15653 2002-10-24 Akim Demaille <akim@epita.fr>
15654
15655 * src/output.c (output_skeleton): Don't disable M4sugar comments
15656 too soon: it results in comments being expanded.
15657 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
15658 first output.
15659
15660 2002-10-24 Akim Demaille <akim@epita.fr>
15661
15662 * data/yacc.c (m4_int_type): New.
15663 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
15664 char' as only yacc.c wants K&R portability.
15665 * data/glr.c (yysigned_char): Remove.
15666 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
15667 Reported by Quoc Peyrot.
15668
15669 2002-10-23 Paul Eggert <eggert@twinsun.com>
15670
15671 * src/main.c (main): With --trace=time, report times even if a
15672 non-fatal error occurs. Formerly, the times were reported in some
15673 such cases but not in others.
15674 * src/reader.c (reader): Just return if a complaint has been issued,
15675 instead of exiting, so that 'main' can report times.
15676
15677 2002-10-22 Akim Demaille <akim@epita.fr>
15678
15679 * src/system.h: Include sys/types.
15680 Reported by Bert Deknuydt.
15681
15682 2002-10-23 Paul Eggert <eggert@twinsun.com>
15683
15684 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
15685 Suggested by Art Haas.
15686
15687 2002-10-22 Paul Eggert <eggert@twinsun.com>
15688
15689 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
15690 decl; not needed any more.
15691 * src/main.c (main): Use return to exit, undoing yesterday's change.
15692 The last OS that we could find where this wouldn't work is
15693 SunOS 3.5, and that's too old to worry about now.
15694
15695 * data/glr.c (struct yyltype): Define members even when not
15696 doing locations. This is more consistent with yacc.c, and it
15697 works around the following bug reports:
15698 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
15699 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
15700
15701 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
15702 @acronym consistently. Standardize on "Yacc" instead of "YACC",
15703 "Algol" instead of "ALGOL". Give a bit more history about BNF.
15704
15705 2002-10-22 Akim Demaille <akim@epita.fr>
15706
15707 * data/README: New.
15708
15709 2002-10-21 Paul Eggert <eggert@twinsun.com>
15710
15711 Be consistent about 'bool'; the old code used an enum in one
15712 module and an int in another, and this violates the C standard.
15713 * m4/stdbool.m4: New file, from coreutils 4.5.3.
15714 * configure.ac (AC_HEADER_STDBOOL): Add.
15715 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
15716 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
15717 * src/symtab.c (hash_compare_symbol_t): Likewise.
15718 * src/system.h (bool, false, true): Use a definition consistent
15719 with ../lib/hash.c. All uses changed.
15720
15721 * src/complain.c (warning_issued): Renamed from warn_message_count,
15722 so that we needn't worry about integer overflow (!).
15723 Now of type bool. All uses changed.
15724 (complaint_issued): Renamed from complain_message_count; likewise.
15725
15726 * src/main.c (main): Use exit to exit with failure.
15727
15728 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
15729 rather than 1 and 0.
15730 * src/main.c (main): Likewise.
15731 * src/getargs.c (getargs): Likewise.
15732 * src/reader.c (reader): Likewise.
15733
15734 * src/getarg.c (getargs): Remove duplicate code for
15735 "Try `bison --help'".
15736
15737 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
15738 What was that "2" for?
15739
15740 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
15741 * src/getargs.c (usage): Likewise.
15742
15743 * src/getargs.c (getargs): When there are too few operands, report
15744 the last one. When there are too many, report the first extra
15745 one. This is how diffutils does it.
15746
15747 2002-10-20 Paul Eggert <eggert@twinsun.com>
15748
15749 Remove K&R vestiges.
15750 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
15751 * src/complain.c (VA_START): Remove. Assume prototypes.
15752 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
15753 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
15754 fatal): Assume prototypes.
15755 * src/complain.h: Assume prototypes.
15756 * src/system.h (PARAMS): Remove.
15757 Include <limits.h> unconditionally, since it's guaranteeed even
15758 for a freestanding C89 compiler.
15759 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
15760 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

15778 (b4_c_function_decl, b4_c_ansi_function_def)
15779 (b4_c_ansi_function_decl): New.
15780 Change the interpretation of the arguments: before `int, foo', now

15783 Adjust b4_c_function_def uses.
15784 * data/glr.c (yyparse): Likewise, but ANSI only.

15786 2002-10-20 Akim Demaille <akim@epita.fr>
15787
15788 * src/output.c (prepare): Move the definition of `tokens_number',
15789 `nterms_number', `undef_token_number', `user_token_number_max'
15790 to...

15804
15805 2002-10-20 Akim Demaille <akim@epita.fr>
15806

15821 2002-10-19 Paul Eggert <eggert@twinsun.com>
15822
15823 Do not create a temporary file, as that involves security and
15824 cleanup headaches. Instead, use a pair of pipes.
15825 Derived from a suggestion by Florian Krohm.
15826 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
15827 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
15828 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
15829 (BISON_PREREQ_SUBPIPE): Add.
15830 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

15836 (scan_skel): New decl.
15837 (output_skeleton): Use pipe rather than temporary file for m4 input.
15838 Check that m4sugar.m4 is readable, to avoid deadlock.
15839 Check for pipe I/O error.
15840 * src/scan-skel.l (readpipe): Remove decl.
15841 (scan_skel): New function, to be used in place of m4_invoke.
15842 Read from stream rather than file.
15843
15844 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
15845 float, as this generates a warning on Solaris 8 + GCC 3.2 with
15846 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
15847 this generates a more-accurate value anyway.
15848
15849 * lib/timevar.c (timervar_accumulate): Rename locals to
15850 avoid confusion with similarly-named more-global.
15851 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
15852
15853 * src/output.c (prepare): Use xstrdup to convert char const *
15854 to char *, to avoid GCC warning.
15855
15856 2002-10-19 Akim Demaille <akim@epita.fr>
15857
15858 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
15859 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
15860 Use them to have `calc.y' ready for %pure-parser.
15861 * data/yacc.c (YYLEX): Pass a yylex return type to
15862 b4_c_function_call.
15863
15864 2002-10-19 Akim Demaille <akim@epita.fr>
15865
15866 Prototype support of %lex-param and %parse-param.
15867
15868 * src/parse-gram.y: Add the definition of the %lex-param and
15869 %parse-param tokens, plus their rules.
15870 Drop the `_' version of %glr-parser.
15871 Add the "," token.
15872 * src/scan-gram.l (INITIAL): Scan them.
15873 * src/muscle_tab.c: Comment changes.
15874 (muscle_insert, muscle_find): Rename `pair' as `probe'.
15875 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
15876 (muscle_entry_s): The `value' member is no longer const.
15877 Adjust all dependencies.
15878 * src/muscle_tab.c (muscle_init): Adjust: use
15879 MUSCLE_INSERT_STRING.
15880 Initialize the obstack earlier.
15881 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
15882 (muscle_pair_list_grow): New.
15883 * data/c.m4 (b4_c_function_call, b4_c_args): New.
15884 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
15885 * tests/calc.at: Use %locations, not --locations.
15886 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
15887
15888 2002-10-19 Akim Demaille <akim@epita.fr>
15889
15890 * src/getargs.c (usage): Take status as argument and exit
15891 accordingly.
15892 Report the traditional `Try ... --help' message when status != 0.
15893 (usage, version): Don't take a FILE * as arg, it is pointless.
15894 (getargs): When there is an incorrect number of arguments, make it
15895 an error, and report it GNUlically thanks to `usage ()'.
15896
15897 2002-10-18 Paul Eggert <eggert@twinsun.com>
15898
15899 * data/glr.c (yyreportParseError): Don't assume that sprintf
15900 yields the length of the printed string, as this is not true
15901 on SunOS 4.1.4. Reported by Peter Klein.
15902
15903 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
15904 * tests/conflicts.at (%nonassoc and eof): Likewise.
15905 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
15906
15907 2002-10-17 Akim Demaille <akim@epita.fr>
15908
15909 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
15910 * src/getargs.c (trace_types, trace_args): Adjust.
15911 * src/reader.c (grammar_current_rule_prec_set)
15912 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
15913 Standardize error messages.
15914 And s/@prec/%prec/!
15915 (reader): Use trace_flag to enable scanner/parser debugging,
15916 instead of an adhoc scheme.
15917 * src/scan-gram.l: Remove trailing debugging code.
15918
15919 2002-10-16 Paul Eggert <eggert@twinsun.com>
15920
15921 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
15922 MUSCLE_TAB_H.
15923
15924 * NEWS: Officially drop support for building Bison with K&R C,
15925 since it didn't work anyway and it's not worth worrying about.
15926 * Makefile.maint (wget_files): Remove ansi2knr.c.
15927 (ansi2knr.c-url_prefix): Remove.
15928 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
15929 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15930 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
15931
15932 2002-10-15 Paul Eggert <eggert@twinsun.com>
15933
15934 Stop using the "enum_" trick for K&R-style function definitions;
15935 it confused me, and I was the author! Instead, assume that people
15936 who want to use K&R C compilers (when using these modules in GCC,
15937 perhaps?) will run ansi2knr.
15938
15939 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
15940 All uses of "enum_" changed to "enum ".
15941 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

15951 abitset_size, abitset_small_list, abitset_subset_p, abitset_test,
15952 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
15953 Use function prototypes; this removes the need for declaring
15954 static functions simply to provide their prototypes.
15955 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

16012 2002-10-14 Akim Demaille <akim@epita.fr>
16013
16014 * tests/Makefile.am (maintainer-check-posix): New.
16015
16016 2002-10-14 Akim Demaille <akim@epita.fr>
16017
16018 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
16019 member.
16020
16021 2002-10-14 Akim Demaille <akim@epita.fr>
16022
16023 * src/tables.c (table_ninf_remap): base -> tab.
16024 Reported by Matt Rosing.
16025
16026 2002-10-14 Paul Eggert <eggert@twinsun.com>
16027
16028 * tests/action.at, tests/calc.at, tests/conflicts.at,
16029 tests/cxx-type.at, tests/headers.at, tests/input.at,
16030 tests/regression.at, tests/synclines.at, tests/torture.at:
16031 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
16032 so that the tests still work even if POSIXLY_CORRECT is set.
16033 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
16034
16035 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
16036 for portability to K&R hosts. Fix typo: signed char is guaranteed
16037 only to 127, not to 128.
16038 * data/glr.c (yysigned_char): New type.
16039 * data/yacc.c (yysigned_char): Likewise.
16040 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
16041
16042 2002-10-13 Paul Eggert <eggert@twinsun.com>
16043
16044 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
16045 true due to limited range of data type" warning from GCC.
16046
16047 * data/c.m4 (b4_token_defines): Protect against double-inclusion
16048 by wrapping enum yytokentype's definition inside #ifndef
16049 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
16050
16051 2002-10-13 Akim Demaille <akim@epita.fr>
16052
16053 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
16054 Un yy- yyrhs to avoid the name clash with the global YYRHS.
16055
16056 2002-10-13 Akim Demaille <akim@epita.fr>
16057
16058 * Makefile.maint: Update from Autoconf 2.54.

16060
16061 2002-10-13 Akim Demaille <akim@epita.fr>
16062
16063 * src/print.c (print_state): Separate the list of solved conflicts
16064 from the other items.
16065 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
16066
16067 2002-10-13 Akim Demaille <akim@epita.fr>
16068
16069 Let nondeterministic skeletons be usable with deterministic
16070 tables.
16071
16072 With the patch, GAWK compiled by GCC without -O2 passes its test
16073 suite using a GLR parser driven by LALR tables. It fails with -O2
16074 because `struct stat' gives two different answers on my machine:
16075 88 (definition of an auto var) and later 96 (memset on this var).
16076 Hence the stack is badly corrumpted. The headers inclusion is to
16077 blame: if I move the awk.h inclusion before GLR's system header
16078 inclusion, the two struct stat have the same size.
16079
16080 * src/tables.c (pack_table): Always create conflict_table.
16081 (token_actions): Always create conflict_list.
16082 * data/glr.c (YYFLAG): Remove, unused.
16083
16084 2002-10-13 Akim Demaille <akim@epita.fr>
16085
16086 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
16087 (O0FLAGS): New.
16088 (VALGRIND, GXX): New.
16089 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
16090 * tests/bison.in: Run $PREBISON a pre-command.
16091 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
16092 (maintainer-check-g++): New.
16093 * Makefile.am (maintainer-check): New.
16094
16095 2002-10-13 Akim Demaille <akim@epita.fr>
16096
16097 * data/glr.c: Formatting changes.
16098 Tweak some trace messages to match yacc.c's.
16099
16100 2002-10-13 Akim Demaille <akim@epita.fr>
16101
16102 GLR parsers sometimes raise parse errors instead of performing the
16103 default reduction.
16104 Reported by Charles-Henry de Boysson.
16105
16106 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
16107 check the length of the traces when %glr.
16108 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
16109 GLR's traces.
16110 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
16111 Test GLR parsers.
16112 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
16113 (yyltype): Remove the yy prefix from the member names.
16114 (yytable): Complete its comment.
16115 (yygetLRActions): Map error action number from YYTABLE from
16116 YYTABLE_NINF to 0.
16117 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
16118 (which was a bug: it should have been YYTABEL_NINF, and yet it was
16119 not satisfying as we could compare an YYACTION computed from
16120 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
16121 only value for error actions.
16122 (yyreportParseError): In verbose parse error messages, don't issue
16123 `error' in the list of expected tokens.
16124 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
16125 next action to perform to match glr.c's decoding.
16126 (yytable): Complete its comment.
16127

16130 Fix problem reported by Henrik Grubbstroem in
16131 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
16132 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
16133 because the Bison parser reads the second action before reducing
16134 the first one.
16135 * src/scan-gram.l (rule_length): New static var.
16136 Use it to keep track of the rule length in the scanner, since
16137 we can't expect the parser to be in lock-step sync with the scanner.
16138 (handle_action_dollar, handle_action_at): Use this var.
16139 * tests/actions.at (Exotic Dollars): Test for the problem.
16140
16141 2002-10-12 Paul Eggert <eggert@twinsun.com>
16142
16143 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
16144 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
16145 Include <sys/time.h> when checking for clock_t and struct tms.
16146 Use same include order as source.
16147 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
16148 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
16149
16150 * lib/timevar.c: Update copyright date and clarify comments.
16151 (get_time) [IN_GCC]: Keep the GCC version for reference.
16152
16153 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
16154 GCC version as of today, then merge Bison's changes.
16155 Change "GCC" to "Bison" in copyright notice. timevar.def's
16156 author is Akim, so change that too.
16157
16158 * src/reader.c (grammar_current_rule_check):
16159 Don't worry about the default action if $$ is untyped.
16160 Prevents bogus warnings reported by Jim Gifford in
16161 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
16162
16163 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
16164 * data/glr.c, data/lalr1.cc, data/yacc.c:
16165 Output token definitions before the first part of user declarations.
16166 Fixes compatibility problem reported by Jim Gifford for kbd in
16167 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
16168
16169 2002-10-11 Paul Eggert <eggert@twinsun.com>
16170
16171 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
16172 (yyparse): here. This undoes some of the 2002-07-25 change.
16173 Compatibility problem reported by Ralf S. Engelschall with
16174 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
16175
16176 2002-10-11 Akim Demaille <akim@epita.fr>
16177
16178 * tests/regression.at Characters Escapes): New.
16179 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
16180 characters.
16181 Reported by Jan Nieuwenhuizen.
16182

16186
16187 2002-10-10 Paul Eggert <eggert@twinsun.com>
16188
16189 Portability fixes for bitsets; this also avoids several GCC
16190 warnings.
16191
16192 * lib/abitset.c: Include <stddef.h>, for offsetof.
16193 * lib/lbitset.c: Likewise.
16194
16195 * lib/abitset.c (abitset_bytes): Return a size that is aligned
16196 properly for vectors of objects. Do not assume that adding a
16197 header size to a multiple of a word size yields a value that is
16198 properly aligned for the whole union.
16199 * lib/bitsetv.c (bitsetv_alloc): Likewise.
16200
16201 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
16202 unique names for structures.
16203 * lib/ebitset.c (ebitset_bytes): Likewise.
16204 * lib/lbitset.c (lbitset_bytes): Likewise.
16205
16206 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
16207 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
16208 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
16209 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
16210 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
16211 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
16212 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
16213 to improve the type-checking that GCC can do.
16214 * lib/bitset.c (bitset_op4_cmp): Likewise.
16215 * lib/bitset_stats.c (bitset_stats_count,
16216 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
16217 bitset_stats_copy, bitset_stats_disjoint_p,
16218 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
16219 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
16220 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
16221 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
16222 bitset_stats_and_or_cmp, bitset_stats_andn_or,
16223 bitset_stats_andn_or_cmp, bitset_stats_or_and,
16224 bitset_stats_or_and_cmp): Likewise.
16225 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
16226 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
16227 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
16228 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
16229
16230 * lib/abitset.h: Include bitset.h, not bbitset.h.
16231 * lib/ebitset.h: Likewise.
16232 * lib/lbitset.h: Likewise.
16233
16234 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
16235 All instances of parameters of type enum bitset_opts are now of
16236 type enum_bitset_opts, to conform to the C Standard, and similarly
16237 for enum_bitset_type.
16238 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
16239 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
16240
16241 Do not use "struct bitset_struct" to mean different things in
16242 different modules. Not only is this confusing, it violates
16243 the C Standard, which requires that structure types in different
16244 modules must be compatible if one is to be passed to the other.
16245 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
16246 All instances of "struct bitset_struct *" replaced with "bitset".
16247 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
16248 (union bitset_union, struct abitset_struct, struct ebitset_struct,
16249 struct lbitset_struct, struct bitset_stats_struct): New types.
16250 All uses of struct bitset_struct changed to union bitset_union,
16251 etc.
16252 * lib/abitset.c (struct abitset_struct, abitset,
16253 struct bitset_struct): Remove.
16254 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
16255 struct bitset_struct): Remove.
16256 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
16257 bitset_struct): Remove.
16258 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
16259 Likewise.
16260
16261 Do not call a function of type T using a call that assumes the
16262 function is of a different type U. Standard C requires that a
16263 function must be called with a type that is compatible with its
16264 definition.
16265 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
16266 New decls.
16267 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
16268 New functions.
16269 * lib/ebitset.c (PFV): Remove.
16270 * lib/lbitset.c (PFV): Likewise.
16271 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
16272 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
16273 decls.
16274 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
16275 (ebitset_vtable): Use them.
16276 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
16277 lbitset_xor): New functions.
16278 (lbitset_vtable): Use them.
16279
16280 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
16281 Declare.
16282
16283 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
16284 GCC warning.
16285 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
16286 Use offsetof, for simplicity.
16287
16288 2002-10-06 Paul Eggert <eggert@twinsun.com>
16289
16290 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
16291 the same width as int. This reapplies a hunk of the 2002-08-12 patch
16292 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
16293 which was inadvertently undone by the 2002-09-30 patch.
16294 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
16295 the same width as int.
16296
16297 2002-10-04 Paul Eggert <eggert@twinsun.com>
16298

16302
16303 * doc/bison.texinfo: Minor spelling, grammar, and white space
16304 fixes.
16305 (Symbols): Mention that any negative value returned from yylex
16306 signifies end-of-input. Warn about negative chars. Mention
16307 the portable Standard C character set.
16308
16309 The GNU coding standard says CFLAGS and YFLAGS are reserved
16310 for the installer to set.
16311 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
16312 * src/Makefile.am (AM_CFLAGS): Likewise.
16313 (AM_YFLAGS): Renamed from YFLAGS.
16314
16315 Fix some MAX and MIN problems.
16316 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.

16318 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
16319 * src/reader.c (reader): Use it.
16320
16321 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
16322 POSIX 1003.1-2001 has removed fgrep.
16323
16324 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
16325
16326 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
16327 interpreted as signed.

16353 Likewise.
16354 * lib/lbitset.c (lbitset_size, lbitset_list, lbitset_list_merge):
16355 Likewise.
16356
16357 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
16358 Use size_t, not unsigned int, to count bytes.
16359 * lib/abitset.h (abitset_bytes): Likewise.
16360 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
16361 Likewise.

16375 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
16376 abitset_or_and, abitset_or_and_cmp):
16377 Use bitset_windex instead of unsigned int.
16378 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
16379 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
16380 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,

16394 BITSET_SIZE_MAX): New macros.
16395 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
16396 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
16397 to BITSET_WINDEX_MAX.
16398
16399 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
16400 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

16499 2002-09-06 Paul Eggert <eggert@twinsun.com>
16500
16501 * doc/bison.texinfo (Conditions): Make explicit that the GPL
16502 exception applies only to yacc.c. This is a modification of a
16503 patch originally suggested by Akim Demaille.
16504
16505 2002-09-06 Akim Demaille <akim@epita.fr>
16506
16507 * data/c.m4 (b4_copyright): Move the GPL exception comment from
16508 here to...
16509 * data/yacc.c: here.
16510
16511 * data/lalr1.cc (struct yyltype): Don't define it, since we use
16512 LocationType.
16513 (b4_ltype): Default to yy::Location from location.hh.
16514
16515 2002-09-04 Jim Meyering <jim@meyering.net>
16516
16517 * data/yacc.c: Guard the declaration of yytoknum also with
16518 `#ifdef YYPRINT', so it is declared only when used.
16519
16520 2002-09-04 Akim Demaille <akim@epita.fr>
16521
16522 * configure.in: Rename as...
16523 * configure.ac: this.
16524 Bump to 1.49c.
16525
16526 2002-09-04 Akim Demaille <akim@epita.fr>
16527

16529 * src/lalr.c, src/LR0.c, src/relation.c, src/tables.c: Don't
16530 translate maintainer only messages.
16531
16532 2002-08-12 Paul Eggert <eggert@twinsun.com>
16533

16535
16536 * Makefile.am (SUBDIRS): Remove intl.
16537 (DISTCLEANFILES): Remove.
16538 * NEWS: Mention that GNU M4 is now required. Clarify what is

16549 * data/glr.c: Include string.h, for strlen.
16550 (yyreportParseError): Use size_t for yysize.
16551 (yy_yypstack): No longer nested inside yypstates, as nested
16552 functions are not portable. Do not assume size_t is the
16553 same width as int.
16554 (yypstates): Do not assume that ptrdiff_t is the same width
16555 as int, and similarly for yyposn and YYINDEX.
16556
16557 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
16558
16559 * lib/Makefile.am (INCLUDES): Do not include from the intl
16560 directory, which has been removed.
16561 * src/Makefile.am (INCLUDES): Likewise.
16562

16567 * lib/Makefile.am (libbison_a_SOURCES): Avoid +=, a GNU make extension.
16568 * tests/Makefile.am (EXTRA_DIST): Likewise.
16569
16570 * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):
16571 Do not assume that bitset_windex is the same width as unsigned.
16572
16573 * lib/abitset.c (abitset_unused_clear): Do not assume that

16593 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
16594 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
16595
16596 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
16597 PROTOTYPES to check for prototypes, and "defined __STDC__" to
16598 check for void *.
16599
16600 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
16601 size_t; the old version tried to do this but casted improperly.
16602 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
16603 (bitset_test): Now returns int, not unsigned long.
16604
16605 * lib/bitset_stats.c: Include "gettext.h".
16606 (_): New macro.
16607 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
16608 name locals "index", as it generates unnecessary warnings on some
16609 hosts that have an "index" function.
16610
16611 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
16612 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

16617 * src/closure.c (print_closure, set_firsts, closure): Likewise.
16618 * src/gram.c (grammar_dump): Likewise.
16619 * src/injections.c (injections_compute): Likewise.
16620 * src/lalr.c (lookaheads_print): Likewise.
16621 * src/relation.c (relation_transpose): Likewise.
16622 * src/scan-gram.l: Likewise.
16623 * src/tables.c (table_grow, pack_vector): Likewise.
16624
16625 * m4/Makefile.am (EXTRA_DIST): Remove codeset.m4,
16626 glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
16627 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
16628 * m4/mbstate_t.m4: Sync with fileutils.
16629 * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.

16633 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
16634 lib/timevar.c.
16635 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
16636 manual recommends.
16637 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
16638
16639 * src/complain.c (strerror_r): Remove decl; not needed.
16640 (strerror): Use same pattern as ../lib/error.c.
16641
16642 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
16643
16644 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
16645
16646 * src/main.c (main): Cast result of bindtextdomain and textdomain
16647 to void, to avoid a GCC warning when --disable-nls is in effect.
16648
16649 * src/scan-gram.l: Use strings rather than escapes when possible,
16650 to minimize the number of warnings from xgettext.
16651 (handle_action_dollar, handle_action_at): Don't use isdigit,
16652 as it mishandles negative chars and it may not work as expected
16653 outside the C locale.
16654
16655 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
16656 this is a GCC extension and is not portable to other compilers.
16657
16658 * src/system.h (alloca): Use same pattern as ../lib/error.c.
16659 Do not include <ctype.h>; no longer needed.
16660 Do not include <malloc.h>; no longer needed (and generates
16661 warnings on OpenBSD 3.0).
16662
16663 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
16664 it's not portable.
16665
16666 * tests/regression.at: Do not use 'cc -c input.c -o input';
16667 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
16668
16669 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
16670 exit status as failure, not just exit status 1. Sun C exits
16671 with status 2 sometimes.
16672
16673 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
16674 Use it for the two large tests.
16675
16676 2002-08-02 Akim Demaille <akim@epita.fr>
16677
16678 * src/conflicts.c (conflicts_output): Don't output rules never
16679 reduced here, since anyway that computation doesn't work.

16681 (rule_useless_p, rule_never_reduced_p): New.
16682 (grammar_rules_partial_print): Use a filter instead of a range.
16683 Display the title only if needed.
16684 (grammar_rules_print): Adjust.
16685 (grammar_rules_never_reduced_report): New.
16686 * src/tables.c (action_row): Move the computation of rules never
16687 reduced to...
16688 (token_actions): here.
16689 * src/main.c (main): Make the parser before making the report, so
16690 that rules never reduced are computed.
16691 Call grammar_rules_never_reduced_report.
16692 * src/print.c (print_results): Report rules never reduced.
16693 * tests/conflicts.at, tests/reduce.at: Adjust.
16694
16695 2002-08-01 Akim Demaille <akim@epita.fr>
16696
16697 Instead of attaching lookaheads and duplicating the rules being
16698 reduced by a state, attach the lookaheads to the reductions.
16699
16700 * src/state.h (state_t): Remove the `lookaheads',
16701 `lookaheads_rule' member.
16702 (reductions_t): Add a `lookaheads' member.
16703 Use a regular array for the `rules'.
16704 * src/state.c (reductions_new): Initialize the lookaheads member
16705 to 0.
16706 (state_rule_lookaheads_print): Adjust.

16712 (state_lookaheads_count): New.
16713 (states_lookaheads_initialize): Merge into...
16714 (initialize_LA): this.
16715 (lalr_free): Adjust.
16716 * src/main.c (main): Don't free nullable and derives too early: it
16717 is used by --verbose.
16718 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
16719
16720 2002-08-01 Akim Demaille <akim@epita.fr>
16721
16722 * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
16723 `rule_number_t**'.

16726 Adjust all dependencies.
16727 * src/nullable.c (set_nullable, free_nullable): Rename as...
16728 (nullable_compute, nullable_free): these.
16729 (rule_list_t): Store rule_t *, not rule_number_t.
16730 * src/state.c (state_rule_lookaheads_print): Directly compare rule
16731 pointers, instead of their numbers.
16732 * src/main.c (main): Call nullable_free, and derives_free earlier,
16733 as they were lo longer used.
16734
16735 2002-08-01 Akim Demaille <akim@epita.fr>
16736
16737 * lib/timevar.c (get_time): Include children time.
16738 * src/lalr.h (LA, LArule): Don't export them: used with the
16739 state_t.
16740 * src/lalr.c (LA, LArule): Static.
16741 * src/lalr.h, src/lalr.c (lalr_free): New.
16742 * src/main.c (main): Call it.
16743 * src/tables.c (pack_vector): Check whether loc is >= to the
16744 table_size, not >.
16745 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
16746 (tables_generate): do it, since that's also it which allocates
16747 them.
16748 Don't free LA and LArule, main does.
16749
16750 2002-07-31 Akim Demaille <akim@epita.fr>
16751
16752 Separate parser tables computation and output.
16753

16755 (conflict_list, conflict_list_cnt, table, check, table_ninf)
16756 (yydefgoto, yydefact, high): Move to...
16757 * src/tables.h, src/tables.c: here.

16763 (conflict_list_free, table_size, lowzero, table_grow, conflict_row)
16764 (action_row, save_row, token_actions, save_column, default_goto)
16765 (goto_actions, sort_actions, matching_state, pack_vector)
16766 (table_ninf_remap, pack_table, prepare_actions): Move to...

16786 * src/getargs.h, src/getargs.c: Support trace_time for
16787 --trace=time.
16788 * src/main.c (stage): Remove.
16789 (main): Replace `stage' invocations with timevar calls.
16790 * src/output.c: Insert pertinent timevar calls.
16791
16792 2002-07-31 Akim Demaille <akim@epita.fr>
16793
16794 Let --trace have arguments.
16795
16796 * src/getargs.h (enum trace_e): New.
16797 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
16798 (long_options, short_options): --trace/-T takes an optional
16799 argument.
16800 Change all the uses of trace_flag to reflect the new flags.
16801 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
16802
16803 Strengthen `stage' portability.
16804
16805 * m4/stage.m4 (BISON_PREREQ_STAGE): New.
16806 * configure.in: Use it.
16807 Don't check for malloc.h and sys/times.h.
16808 * src/system.h: Include them when appropriate.
16809 * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
16810 times and struct tms are available.
16811
16812 2002-07-30 Akim Demaille <akim@epita.fr>
16813
16814 In verbose parse error message, don't report `error' as an
16815 expected token.
16816 * tests/actions.at (Printers and Destructors): Adjust.
16817 * tests/calc.at (Calculator $1): Adjust.
16818 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
16819 error message, do not report the parser accepts the error token in
16820 that state.
16821
16822 2002-07-30 Akim Demaille <akim@epita.fr>
16823

16834 Report rules which are never reduced by the parser: those hidden
16835 by conflicts.
16836
16837 * src/LR0.c (save_reductions): Don't make the final state too
16838 different: save its reduction (accept) instead of having a state
16839 without any action (no shift or goto, no reduce).
16840 Note: the final state is now a ``regular'' state, i.e., the
16841 parsers now contain `reduce 0' as default reduction.
16842 Nevertheless, since they decide to `accept' when yystate =
16843 final_state, they still will not reduce rule 0.
16844 * src/print.c (print_actions, print_reduction): Adjust.
16845 * src/output.c (action_row): Track reduced rules.
16846 (token_actions): Report rules never reduced.

16852 Initiate its autoconfiscation.
16853
16854 * configure.in: Look for malloc.h and sys/times.h.
16855 * src/main.c (stage): Adjust.
16856 Report only when trace_flag.
16857
16858 2002-07-29 Akim Demaille <akim@epita.fr>
16859
16860 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not
16861 state_number_t.
16862 (errs_t): symbol_t*, not symbol_number_t.
16863 (reductions_t): rule_t*, not rule_number_t.

16865 * src/LR0.c, src/conflicts.c, src/lalr.c, src/output.c
16866 * src/print.c, src/print_graph.c: Adjust.
16867
16868 2002-07-29 Akim Demaille <akim@epita.fr>
16869
16870 Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $.
16871
16872 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
16873 (endtoken, accept): these.
16874 * src/reader.c (reader): Set endtoken's default tag to "$end".
16875 Set undeftoken's tag to "$undefined" instead of "$undefined.".
16876 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
16877 Adjust.
16878
16879 2002-07-29 Akim Demaille <akim@epita.fr>
16880
16881 * src/reduce.c (reduce_grammar): When the language is empty,
16882 complain about the start symbol, not the axiom.
16883 Use its location.
16884 * tests/reduce.at (Empty Language): New.
16885
16886 2002-07-26 Akim Demaille <akim@epita.fr>
16887
16888 * src/reader.h, src/reader.c (gram_error): ... can't get
16889 yycontrol without making too strong assumptions on the parser
16890 itself.
16891 * src/output.c (prepare_tokens): Use the real 0th value of
16892 token_translations instead of `0'.
16893 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
16894 visible here.
16895 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
16896 for the time being: %locations ought to provide it to yyerror.
16897
16898 2002-07-25 Akim Demaille <akim@epita.fr>
16899
16900 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
16901 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.

18570 * src/lex.c, src/nullable.c, src/output.c, src/print.c,
18571 * src/print_graph.c, src/reader.c, src/reduce.c, src/state.h,
18572 * src/symtab.c, src/symtab.h: Use token_number_t instead of shorts.
18573
18574 2002-04-22 Akim Demaille <akim@epita.fr>
18575
18576 * src/output.h, src/output.c (get_lines_number): Remove.
18577
18578 2002-04-19 Akim Demaille <akim@epita.fr>
18579
18580 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
18581 as Lex/Flex'.
18582 (Debugging): More details about enabling the debugging features.
18583 (Table of Symbols): Describe $$, $n, @$, and @n.
18584 Suggested by Tim Josling.
18585
18586 2002-04-19 Akim Demaille <akim@epita.fr>
18587
18588 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
18589
18590 2002-04-10 Akim Demaille <akim@epita.fr>
18591
18592 * src/system.h: Rely on HAVE_LIMITS_H.
18593 Suggested by Paul Eggert.
18594
18595 2002-04-09 Akim Demaille <akim@epita.fr>
18596
18597 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
18598 full stderr, and strip it according to the bison options, instead
18599 of composing the error message from different bits.
18600 This makes it easier to check for several error messages.
18601 Adjust all the invocations.
18602 Add an invocation exercising the error token.
18603 Add an invocation demonstrating a stupid error message.
18604 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
18605 Adjust the tests.
18606 Error message are for stderr, not stdout.
18607
18608 2002-04-09 Akim Demaille <akim@epita.fr>
18609
18610 * src/gram.h, src/gram.c (error_token_number): Remove, use
18611 errtoken->number.
18612 * src/reader.c (reader): Don't specify the user token number (2)
18613 for $undefined, as it uselessly prevents using it.
18614 * src/gram.h (token_number_t): Move to...
18615 * src/symtab.h: here.
18616 (state_t.number): Is a token_number_t.
18617 * src/print.c, src/reader.c: Use undeftoken->number instead of
18618 hard coded 2.
18619 (Even though this 2 is not the same as above: the number of the
18620 undeftoken remains being 2, it is its user token number which
18621 might not be 2).
18622 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
18623 `user_token_number_max'.
18624 Output `undef_token_number'.
18625 * data/bison.simple, data/bison.c++: Use them.
18626 Be sure to map invalid yylex return values to
18627 `undef_token_number'. This saves us from gratuitous SEGV.
18628
18629 * tests/conflicts.at (Solved SR Conflicts)
18630 (Unresolved SR Conflicts): Adjust.
18631 * tests/regression.at (Web2c Actions): Adjust.

18636 Adding #line.
18637 Remove the duplicate `typedefs'.
18638 (RhsNumberType): Fix the declaration and various other typos.
18639 Use __ofile__.
18640 * data/bison.simple: Use __ofile__.
18641 * src/scan-skel.l: Handle __ofile__.
18642
18643 2002-04-08 Akim Demaille <akim@epita.fr>
18644
18645 * src/gram.h (item_number_t): New, the type of item numbers in
18646 RITEM. Note that it must be able to code symbol numbers as
18647 positive number, and the negation of rule numbers as negative
18648 numbers.
18649 Adjust all dependencies (pretty many).
18650 * src/reduce.c (rule): Remove this `short *' pointer: use
18651 item_number_t.
18652 * src/system.h (MINSHORT, MAXSHORT): Remove.
18653 Include `limits.h'.
18654 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
18655 (shortcpy): Remove.
18656 (MAXTABLE): Move to...
18657 * src/output.c (MAXTABLE): here.

18660 * tests/torture.at (Big triangle): Move the limit from 254 to
18661 500.
18662 * tests/regression.at (Web2c Actions): Ajust.
18663
18664 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
18665 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
18666 passes, but produces negative #line number, once fixed, GCC is
18667 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
18668 C), it passes.
18669 * src/state.h (state_h): Code input lines on ints, not shorts.
18670
18671 2002-04-08 Akim Demaille <akim@epita.fr>
18672
18673 * src/reduce.c (reduce_grammar): First reduce the nonterminals,
18674 and then the grammar.

18683 * src/output.c (output_table_data): Return the longest number.
18684 (prepare_tokens): Output `token_number_max').
18685 * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
18686 New.
18687 Use them to define yy_token_number_type/TokenNumberType.
18688 Use this type for yytranslate.
18689 * tests/torture.at (Big triangle): Push the limit from 124 to
18690 253.
18691 * tests/regression.at (Web2c Actions): Adjust.
18692
18693 2002-04-07 Akim Demaille <akim@epita.fr>
18694
18695 * tests/torture.at (Big triangle): New.
18696 (GNU AWK Grammar, GNU Cim Grammar): Move to...
18697 * tests/existing.at: here.

18761 2002-04-07 Akim Demaille <akim@epita.fr>
18762
18763 * src/gram.h (rule_s): prec and precsym are now pointers
18764 to the bucket giving the priority/associativity.
18765 Member `associativity' removed: useless.

18795 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
18796
18797 2002-04-07 Akim Demaille <akim@epita.fr>

18803 (prepare_tokens): this.

18823 new_state.
18824 * src/closure.c (closure): Now that the initial state has its
18825 items properly set, there is no need for a special case when
18826 creating `ruleset'.
18827
18828 As a result, now the rule 0, reducing to $axiom, is visible in the
18829 outputs. Adjust the test suite.

18845 bucket.
18846 Adjust all dependencies.
18847 * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
18848 `number' of the buckets too.
18849 * src/gram.h: Include `symtab.h'.
18850 (associativity): Move to...

18863 * src/print.c (print_grammar): It is no longer needed to check for
18864 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

18867 2002-04-07 Akim Demaille <akim@epita.fr>
18868
18869 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
18870 lacking `+ 1' to nrules, Bison reported as useless a token if it
18871 was used solely to set the precedence of the last rule...
18872
18873 2002-04-07 Akim Demaille <akim@epita.fr>
18874
18875 * data/bison.c++, data/bison.simple: Don't output the current file
18876 name in #line, to avoid useless diffs between two identical
18877 outputs under different names.

18880

18896 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
18897 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
18898 RHS, instead of being an index in RITEMS.

18972
18973 * src/reader.c (read_additionnal_code): `c' should be an integer, not

19166
19167 2002-02-14 Paul Eggert <eggert@twinsun.com>
19168
19169 Remove the support for C++ namespace cleanliness; it was
19170 causing more problems than it was curing, since it didn't work
19171 properly on some nonstandard C++ compilers. This can wait
19172 for a proper C++ parser.
19173
19174 * NEWS: Document this.

19214 2002-02-07 Robert Anisko <robert@lrde.epita.fr>

19217 more consistent when naming methods and variables. Put preprocessor
19218 directives around tables only needed for debugging.
19219
19220 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
19221
19222 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

19262 (token_definitions_output): No longer keeps track of the output
19263 line number, hence remove the second argument.
19264 (guards_output): Check against the guard member of a rule, not the
19265 action member.
19266 Adjust callers.
19267 (output_skeleton): Don't look for the skeleton location, let m4 do
19268 that.
19269 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
19270 file will be used.
19271 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
19272 (prepare): Given that for the time being changesyntax is not
19273 usable in M4, rename the muscles using `-' to `_'.
19274 Define `defines_flag', `output_parser_name' and `output_header_name'.
19275 * src/output.h (actions_output, guards_output)
19276 (token_definitions_output): Adjust prototypes.
19277 * src/scan-skel.l: Instead of scanning the skeletons, it now
19278 processes the output of m4: `__oline__' and `#output'.

19280 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
19281 to date.

19304
19305 * src/bison.simple (YYSIZE_T): Do not define merely because

19309 2002-01-27 Akim Demaille <akim@epita.fr>
19310
19311 Fix `%nonassoc and eof'.
19312
19313 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
19314 which were not properly copied! Replace
19315 memcpy (res->errs, src->errs, src->nerrs);
19316 with
19317 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
19318 !!!
19319 * tests/regression.at (%nonassoc and eof): Adjust to newest
19320 Autotest: `.' is not in the PATH.

19415 * src/getargs.c (AS_FILE_NAME): New.
19416 (getargs): Use it to convert DOSish file names.
19417 * src/files.c (base_name): Rename as full_base_name to avoid
19418 clashes with `base_name ()'.
19419 (filename_split): New.
19420 (compute_base_names): N-th rewrite, using filename_split.
19421
19422 2002-01-08 Akim Demaille <akim@epita.fr>
19423
19424 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
19425 New, stolen from the Fileutils 4.1.
19426 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
19427 * configure.in: Check for the presence of memrchr, and of its
19428 prototype.
19429
19430 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
19431
19432 * lib/hash.h (__P): Added definition for this macro.
19433 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
19434 BUILT_SOURCES, to ensure they are generated first.
19435 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
19436 %error-verbose to allow bootstrapping with bison 1.30x.
19437
19438 2002-01-06 Akim Demaille <akim@epita.fr>
19439
19440 * src/reader.c (parse_braces): Don't fetch the next char, the
19441 convention is to fetch on entry.
19442 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
19443 'switch' without a following semicolon.
19444 * tests/regression.at (braces parsing): New.
19445
19446 2002-01-06 Akim Demaille <akim@epita.fr>
19447
19448 Bison is dead wrong in its RR conflict reports.
19449
19450 * tests/torture.at (GNU Cim Grammar): New.
19451 * src/conflicts.c (count_rr_conflicts): Fix.
19452
19453 2002-01-06 Akim Demaille <akim@epita.fr>
19454
19455 Creating package.m4 from configure.ac causes too many problems.
19456
19457 * tests/Makefile.am (package.m4): Create it by hand,
19458 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
19459
19460 2002-01-06 Akim Demaille <akim@epita.fr>
19461
19462 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
19463 skeleton.h.
19464
19465 2002-01-04 Paul Eggert <eggert@twinsun.com>
19466
19467 * doc/bison.texinfo (Debugging):
19468 Remove YYSTDERR; it's no longer defined or used.
19469 Also, s/cstdio.h/cstdio/.
19470
19471 2002-01-03 Akim Demaille <akim@epita.fr>
19472
19473 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
19474
19475 2002-01-03 Akim Demaille <akim@epita.fr>
19476
19477 * src/parse-skel.y (process_skeleton): Don't bind the parser's
19478 tracing code to --trace, wait for a better --trace option, with
19479 args.
19480
19481 2002-01-03 Akim Demaille <akim@epita.fr>
19482
19483 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
19484 The ISO C++ standard is extremely clear about it: stderr is
19485 considered a macro, not a regular symbol (see table 94 `Header
19486 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
19487 Therefore std:: does not apply to it. It still does with fprintf.
19488 Also, s/cstdio.h/cstdio/.
19489
19490 2002-01-03 Akim Demaille <akim@epita.fr>
19491
19492 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
19493 for non system headers.
19494
19495 2002-01-02 Akim Demaille <akim@epita.fr>
19496
19497 Equip the skeleton chain with location tracking, runtime trace,
19498 pure parser and scanner.
19499
19500 * src/parse-skel.y: Request a pure parser, locations, and prefix
19501 renaming.
19502 (%union): Having several members with the same type does not help
19503 type mismatches, simplify.
19504 (YYPRINT, yyprint): New.
19505 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
19506 (skel_error): this.
19507 Handle locations.
19508 * src/scan-skel.l: Adjust to these changes.
19509 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
19510 (LOCATION_PRINT, skel_control_t): New.
19511
19512 2001-12-30 Akim Demaille <akim@epita.fr>
19513
19514 * src/parse-skel.y: Get rid of the shift/reduce conflict:
19515 replace `gb' with BLANKS.
19516 * src/scan-skel.l: Adjust.
19517
19518 2001-12-30 Akim Demaille <akim@epita.fr>
19519
19520 * src/system.h: We don't need nor want bcopy.
19521 Throw away MS-DOS crap: we don't need getpid.
19522 * configure.in: We don't need strndup. It was even causing
19523 problems: because Flex includes the headers *before* us,
19524 _GNU_SOURCE is not defined by config.h, and therefore strndup was
19525 not visible.
19526 * lib/xstrndup.c: New.
19527 * src/scan-skel.l: Use it.
19528 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
19529 * src/parse-skel.y: Use %directives instead of #defines.
19530
19531 2001-12-30 Akim Demaille <akim@epita.fr>
19532
19533 * src/skeleton.h: New.
19534 * src/output.c (output_parser, output_master_parser): Remove, dead
19535 code.
19536 * src/output.h (get_lines_number, actions_output, guards_output)
19537 (token_definitions_output): Prototype them.
19538 * src/parse-skel.y: Add the license notice.
19539 Include output.h and skeleton.h.
19540 (process_skeleton): Returns void, and takes a single parameter.
19541 * src/scan-skel.l: Add the license notice.
19542 Include skeleton.h.
19543 Don't use %option yylineno: it seems that then Flex imagines
19544 REJECT has been used, and therefore it won't reallocate its
19545 buffers (which makes no other sense to me than a bug). It results
19546 in warnings for `unused: yy_flex_realloc'.
19547
19548 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
19549
19550 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
19551 (MUSCLE_INSERT_PREFIX): ...to there.
19552 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
19553 (MUSCLE_INSERT_PREFIX): Move from here...
19554
19555 * src/bison.hairy: Add a section directive. Put braces around muscle
19556 names. This parser skeleton is still broken, but Bison should not
19557 choke on a bad muscle 'syntax'.
19558 * src/bison.simple: Add a section directive. Put braces around muscle
19559 names.
19560
19561 * src/files.h (strsuffix, stringappend): Add declarations.
19562 (tab_extension): Add declaration.
19563 (short_base_name): Add declaration.
19564
19565 * src/files.c (strsuffix, stringappend): No longer static. These
19566 functions are used in the skeleton parser.
19567 (tab_extension): New.
19568 (compute_base_names): Use the computations done in this function
19569 to guess if the generated parsers should have '.tab' in their
19570 names.
19571 (short_base_name): No longer static.
19572
19573 * src/output.c (output_skeleton): New.
19574 (output): Disable call to output_master_parser, and give a try to
19575 a new skeleton handling system.
19576 (guards_output, actions_output): No longer static.
19577 (token_definitions_output, get_lines_number): No longer static.
19578
19579 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
19580
19581 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
19582 parse-skel.y.
19583
19584 * src/parse-skel.y: New file.
19585 * src/scan-skel.l: New file.
19586
19587 2001-12-29 Akim Demaille <akim@epita.fr>
19588
19589 %name-prefix is broken.
19590
19591 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
19592 Adjust all dependencies.
19593 * tests/headers.at (export YYLTYPE): Strengthen this test: use
19594 %name-prefix.
19595
19596 Renaming yylval but not yylloc is not consistent. Now we do.
19597
19598 * src/bison.simple: Prefix yylloc if used.
19599 * doc/bison.texinfo (Decl Summary): Document that.
19600
19601 2001-12-29 Akim Demaille <akim@epita.fr>
19602
19603 * doc/bison.texinfo: Promote `%long-directive' over
19604 `%long_directive'.
19605 Remove all references to fixed-output-files, yacc is enough.
19606
19607 2001-12-29 Akim Demaille <akim@epita.fr>
19608
19609 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
19610 user prologue. These are defaults.
19611 * tests/actions.at (Mid-rule actions): Make sure the user can
19612 define YYDEBUG and YYERROR_VERBOSE.
19613
19614 2001-12-29 Akim Demaille <akim@epita.fr>
19615
19616 * src/output.c (header_output): Don't forget to export YYLTYPE and
19617 yylloc.
19618 * tests/headers.at (export YYLTYPE): New, make sure it does.
19619 * tests/regression.at (%union and --defines, Invalid CPP headers):
19620 Move to...
19621 * tests/headers.at: here.
19622
19623 2001-12-29 Akim Demaille <akim@epita.fr>
19624
19625 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
19626
19627 2001-12-29 Akim Demaille <akim@epita.fr>
19628
19629 * tests/actions.at (Mid-rule actions): Output on a single line
19630 instead of several.
19631
19632 2001-12-29 Akim Demaille <akim@epita.fr>
19633
19634 * doc/bison.texinfo: Formatting changes.
19635
19636 2001-12-29 Akim Demaille <akim@epita.fr>
19637
19638 Don't store the token defs in a muscle, just be ready to output it
19639 on command. Now possible via `symbols'. Fixes a memory leak.
19640
19641 * src/output.c (token_definitions_output): New.
19642 (output_parser, header_output): Use it.
19643 * src/reader.c (symbols_save): Remove.
19644
19645 2001-12-29 Akim Demaille <akim@epita.fr>
19646
19647 * src/bison.simple: Do not provide a default for YYSTYPE and
19648 YYLTYPE before the user's prologue. Otherwise it's hardly... a
19649 default.
19650
19651 2001-12-29 Akim Demaille <akim@epita.fr>
19652
19653 Mid-rule actions are simply... ignored!
19654
19655 * src/reader.c (readgram): Be sure to attach mid-rule actions to
19656 the empty-rule associated to the dummy symbol, not to the host
19657 rule.
19658 * tests/actions.at (Mid-rule actions): New.
19659
19660 2001-12-29 Akim Demaille <akim@epita.fr>
19661
19662 Memory leak.
19663
19664 * src/reader.c (reader): Free grammar.
19665
19666 2001-12-29 Akim Demaille <akim@epita.fr>
19667
19668 Memory leak.
19669
19670 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
19671 since it allocates it for each state, although only one is needed.
19672 (allocate_storage): Do it here.
19673
19674 2001-12-29 Akim Demaille <akim@epita.fr>
19675
19676 * src/options.h, src/options.c (create_long_option_table): Rename
19677 as...
19678 (long_option_table_new): this, with a clearer prototype.
19679 (percent_table): Remove, unused,
19680 * src/getargs.c (getargs): Adjust.
19681
19682 2001-12-29 Akim Demaille <akim@epita.fr>
19683
19684 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
19685 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
19686 as states.
19687
19688 2001-12-29 Akim Demaille <akim@epita.fr>
19689
19690 * src/lalr.c (build_relations): Rename `states' as `states1'.
19691 Sorry, I don't understand exactly what it is, no better name...
19692
19693 2001-12-29 Akim Demaille <akim@epita.fr>
19694
19695 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
19696 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
19697 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
19698 as rules.
19699
19700 2001-12-29 Akim Demaille <akim@epita.fr>
19701
19702 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
19703 ago.
19704
19705 2001-12-29 Akim Demaille <akim@epita.fr>
19706
19707 * src/reader.c, src/reader.h (user_toknums): Remove.
19708 Adjust all users to use symbols[i]->user_token_number.
19709
19710 2001-12-29 Akim Demaille <akim@epita.fr>
19711
19712 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
19713 Adjust all users to use symbols[i]->prec or ->assoc.
19714
19715 2001-12-29 Akim Demaille <akim@epita.fr>
19716
19717 * src/reader.c, src/reader.h (tags): Remove.
19718 Adjust all users to use symbols[i]->tag.
19719
19720 2001-12-29 Akim Demaille <akim@epita.fr>
19721
19722 * src/gram.h, src/gram.c (symbols): New, similar to state_table
19723 and rule_table.
19724 * src/reader.c (packsymbols): Fill this table.
19725 Drop sprec.
19726 * src/conflicts.c (resolve_sr_conflict): Adjust.
19727 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
19728 single table.
19729 Use symbols[i]->tag instead of tags[i].
19730
19731 2001-12-29 Akim Demaille <akim@epita.fr>
19732
19733 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
19734 In addition, put a comment in there, to replace...
19735 * tests/regression.at (%union and C comments): Remove.
19736
19737 2001-12-29 Akim Demaille <akim@epita.fr>
19738
19739 * tests/regression.at (Web2c Actions): Blindly move the actual
19740 output as expected output. The contents *seem* right to me, but I
19741 can't pretend reading perfectly parser tables... Nonetheless, all
19742 the other tests pass correctly, the table look OK, even though the
19743 presence of `$axiom' is to be noted: AFAICS it is useless (but
19744 harmless).
19745
19746 2001-12-29 Akim Demaille <akim@epita.fr>
19747
19748 * src/reader.c (readgram): Don't add the rule 0 if there were no
19749 rules read. In other words, add it _after_ having performed
19750 grammar sanity checks.
19751 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
19752
19753 2001-12-29 Akim Demaille <akim@epita.fr>
19754
19755 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
19756 visible, and some states have now a different number.
19757
19758 2001-12-29 Akim Demaille <akim@epita.fr>
19759
19760 * src/reader.c (readgram): Bind the initial rule's lineno to that
19761 of the first rule.
19762 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
19763 (Solved SR Conflicts): Adjust rule 0's line number.
19764
19765 2001-12-29 Akim Demaille <akim@epita.fr>
19766
19767 Fix the `GAWK Grammar' failure.
19768
19769 * src/LR0.c (final_state): Initialize to -1 so that we do compute
19770 the reductions of the first state which was mistakenly confused
19771 with the final state because precisely final_state was initialized
19772 to 0.
19773 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
19774 now noticed by Bison.
19775 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
19776 have a reduction on $default.
19777
19778 2001-12-29 Akim Demaille <akim@epita.fr>
19779
19780 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
19781 rule line numbers.
19782 * src/closure.c (print_closure): Likewise.
19783 * src/derives.c (print_derives): Likewise.
19784 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
19785 now.
19786
19787 2001-12-29 Akim Demaille <akim@epita.fr>
19788
19789 * src/lalr.c (lookaheads_print): New.
19790 (lalr): Call it when --trace-flag.
19791 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
19792 are dumped.
19793
19794 2001-12-29 Akim Demaille <akim@epita.fr>
19795
19796 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
19797 when walking through ritem, even via rule->rhs.
19798 * src/reduce.c (dump_grammar, useful_production, reduce_output)
19799 (useful_production, useless_nonterminals): Likewise.
19800 (reduce_grammar_tables): Likewise, plus update nritems.
19801 * src/nullable.c (set_nullable): Likewise.
19802 * src/lalr.c (build_relations): Likewise.
19803 * tests/sets.at (Nullable): Adjust.
19804 Fortunately, now, the $axiom is no longer nullable.
19805
19806 2001-12-29 Akim Demaille <akim@epita.fr>
19807
19808 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
19809 the 0-sentinel.
19810 * src/gram.c (ritem_longest_rhs): Likewise.
19811 * src/reduce.c (nonterminals_reduce): Likewise.
19812 * src/print_graph.c (print_graph): Likewise.
19813 * src/output.c (output_rule_data): Likewise.
19814 * src/nullable.c (set_nullable): Likewise.
19815
19816 2001-12-29 Akim Demaille <akim@epita.fr>
19817
19818 * src/output.c: Comment changes.
19819
19820 2001-12-27 Paul Eggert <eggert@twinsun.com>
19821
19822 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
19823 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
19824 Sparc, as they were causing more porting problems than the
19825 (minor) performance improvement was worth.
19826
19827 Also, catch up with 1.31's YYSTD.
19828
19829 2001-12-27 Akim Demaille <akim@epita.fr>
19830
19831 * src/output.c (output_gram): Rely on nritems, not the
19832 0-sentinel. See below.
19833 Use -1 as separator, not 0.
19834 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
19835 Rely on -1 as separator in yyrhs, instead of 0.
19836 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
19837 twice `Now at end of input', therefore there are two lines less to
19838 expect.
19839
19840 2001-12-27 Akim Demaille <akim@epita.fr>
19841
19842 * tests/regression.at (Unresolved SR Conflicts):
19843 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
19844 below.
19845
19846 2001-12-27 Akim Demaille <akim@epita.fr>
19847
19848 * src/LR0.c (new_state): Recognize the final state by the fact it
19849 is reached by eoftoken.
19850 (insert_start_shifting_state, insert_eof_shifting_state)
19851 (insert_accepting_state, augment_automaton): Remove, since now
19852 these states are automatically computed from the initial state.
19853 (generate_states): Adjust.
19854 * src/print.c: When reporting a rule number to the user, substract
19855 1, so that the axiom rule is rule 0, and the first user rule is 1.
19856 * src/reduce.c: Likewise.
19857 * src/print_graph.c (print_core): For the time being, just as for
19858 the report, depend upon --trace-flags to dump the full set of
19859 items.
19860 * src/reader.c (readgram): Once the grammar read, insert the rule
19861 0: `$axiom: START-SYMBOL $'.
19862 * tests/set.at: Adjust: rule 0 is now displayed, and since the
19863 number of the states has changed (the final state is no longer
19864 necessarily the last), catch up.
19865
19866 2001-12-27 Akim Demaille <akim@epita.fr>
19867
19868 Try to make the use of the eoftoken valid. Given that its value
19869 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
19870 is used instead of > 0 where appropriate, (ii), depend upon nritems
19871 instead of the 0-sentinel.
19872
19873 * src/gram.h, src/gram.c (nritems): New.
19874 Expected to be duplication of nitems, but for the time being...
19875 * src/reader.c (packgram): Assert nritems and nitems are equal.
19876 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
19877 * src/closure.c (print_closure, print_fderives): Likewise.
19878 * src/gram.c (ritem_print): Likewise.
19879 * src/print.c (print_core, print_grammar): Likewise.
19880 * src/print_graph.c: Likewise.
19881
19882 2001-12-27 Akim Demaille <akim@epita.fr>
19883
19884 * src/main.c (main): If there are complains after grammar
19885 reductions, then output the report anyway if requested, then die.
19886 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
19887 * src/reader.c (eoftoken): New.
19888 (parse_token_decl): If the token being defined has value `0', it
19889 is the eoftoken.
19890 (packsymbols): No longer hack `tags' to insert `$' by hand.
19891 Be sure to preserve the value of the eoftoken.
19892 (reader): Make sure eoftoken is defined.
19893 Initialize nsyms to 0: now eoftoken is created just like the others.
19894 * src/print.c (print_grammar): Don't special case the eof token.
19895 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
19896 lie anyway, albeit pleasant.
19897 * tests/calc.at: Exercise error messages with eoftoken.
19898 Change the grammar so that empty input is invalid.
19899 Adjust expectations.
19900 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
19901
19902 2001-12-27 Akim Demaille <akim@epita.fr>
19903
19904 * configure.in: Check the protos of strchr ans strspn.
19905 Replace strchr if needed.
19906 * src/system.h: Provide the protos of strchr, strspn and memchr if
19907 missing.
19908 * lib/strchr.c: New.
19909 * src/reader.c (symbols_save): Use strchr.
19910
19911 2001-12-27 Akim Demaille <akim@epita.fr>
19912
19913 * src/print.c, src/print_graph.c (escape): New.
19914 Use it to quote the TAGS outputs.
19915 * src/print_graph.c (print_state): Now errors are in red, and
19916 reductions in green.
19917 Prefer high to wide: output the state number on a line of its own.
19918
19919 2001-12-27 Akim Demaille <akim@epita.fr>
19920
19921 * src/state.h, src/state.c (reductions_new): New.
19922 * src/LR0.c (set_state_table): Let all the states have a
19923 `reductions', even if reduced to 0.
19924 (save_reductions): Adjust.
19925 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
19926 * src/print.c (print_reductions, print_actions): Adjust.
19927 * src/output.c (action_row): Adjust.
19928
19929 2001-12-27 Akim Demaille <akim@epita.fr>
19930
19931 * src/state.h, src/state.c (errs_new, errs_dup): New.
19932 * src/LR0.c (set_state_table): Let all the states have an errs,
19933 even if reduced to 0.
19934 * src/print.c (print_errs, print_reductions): Adjust.
19935 * src/output.c (output_actions, action_row): Adjust.
19936 * src/conflicts.c (resolve_sr_conflict): Adjust.
19937
19938 2001-12-27 Akim Demaille <akim@epita.fr>
19939
19940 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
19941
19942 2001-12-27 Akim Demaille <akim@epita.fr>
19943
19944 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
19945 * src/print.c: here.
19946 (lookaheadset, shiftset): New, used as additional storage by
19947 print_reductions.
19948 (print_results): Adjust.
19949 (print_shifts, print_gotos, print_errs): New, extracted from...
19950 (print_actions): here.
19951 * src/print_graph.c (print_actions): Remove dead code.
19952
19953 2001-12-27 Akim Demaille <akim@epita.fr>
19954
19955 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
19956 `$n' and `@n'.
19957
19958 2001-12-27 Akim Demaille <akim@epita.fr>
19959
19960 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
19961 (build_relations): Adjust.
19962
19963 2001-12-27 Akim Demaille <akim@epita.fr>
19964
19965 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
19966 duplication.
19967
19968 2001-12-27 Akim Demaille <akim@epita.fr>
19969
19970 * src/reader.c (packgram): Catch nitems overflows.
19971
19972 2001-12-27 Akim Demaille <akim@epita.fr>
19973
19974 * src/files.c, src/files.h (guard_obstack): Remove.
19975 * src/output.c (output): Adjust.
19976 * src/reader.c (parse_braces): New, factoring...
19977 (copy_action, copy_guard): these two which are renamed as...
19978 (parse_action, parse_guard): these.
19979 As a voluntary consequence, using braces around guards is now
19980 mandatory.
19981
19982 2001-12-27 Akim Demaille <akim@epita.fr>
19983
19984 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
19985 * src/reader.c (symbol_list): `guard' and `guard_line' are new
19986 members.
19987 (symbol_list_new): Adjust.
19988 (copy_action): action_line is the first line, not the last.
19989 (copy_guard): Just as for actions, store the `action' only, not
19990 the switch/case/break flesh.
19991 Don't parse the user action that might follow the guard, let...
19992 (readgram): do it, i.e., now, there can be an action after a
19993 guard.
19994 In other words the guard is just explicitly optional.
19995 (packgram): Adjust.
19996 * src/output.c (guards_output): New.
19997 (output_parser): Call it when needed.
19998 (output): Also free the guard and attrs obstacks.
19999 * src/files.c, src/files.h (obstack_save): Remove.
20000 (output_files): Remove.
20001 As a result, if one needs the former `.act' file, using an
20002 appropriate skeleton which requires actions and guards is now
20003 required.
20004 * src/main.c (main): Adjust.
20005 * tests/semantic.at: New.
20006 * tests/regression.at: Use `input.y' as input file name.
20007 Avoid 8+3 problems by requiring input.c when the test needs the
20008 parser.
20009
20010 2001-12-27 Akim Demaille <akim@epita.fr>
20011
20012 * src/reader.c (symbol_list_new): Be sure to initialize all the
20013 fields.
20014
20015 2001-12-27 Akim Demaille <akim@epita.fr>
20016
20017 All the hacks using a final pseudo state are now useless.
20018
20019 * src/LR0.c (set_state_table): state_table holds exactly nstates.
20020 * src/lalr.c (nLA): New.
20021 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
20022 instead of lookaheadsp from the pseudo state (nstate + 1).
20023
20024 2001-12-27 Akim Demaille <akim@epita.fr>
20025
20026 * src/output.c (action_row, token_actions): Use a state_t instead
20027 of a integer, and nlookaheads instead of the following state's
20028 lookaheadsp.
20029
20030 2001-12-27 Akim Demaille <akim@epita.fr>
20031
20032 * src/conflicts.c (log_resolution, flush_shift)
20033 (resolve_sr_conflict, set_conflicts, solve_conflicts)
20034 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
20035 (conflicts_print, print_reductions): Use a state_t instead of an
20036 integer when referring to a state.
20037 As much as possible, depend upon nlookaheads, instead of the
20038 `lookaheadsp' member of the following state (since lookaheads of
20039 successive states are successive, the difference between state n + 1
20040 and n served as the number of lookaheads for state n).
20041 * src/lalr.c (add_lookback_edge): Likewise.
20042 * src/print.c (print_core, print_actions, print_state)
20043 (print_results): Likewise.
20044 * src/print_graph.c (print_core, print_actions, print_state)
20045 (print_graph): Likewise.
20046 * src/conflicts.h: Adjust.
20047
20048 2001-12-27 Akim Demaille <akim@epita.fr>
20049
20050 * src/bison.hairy: Formatting/comment changes.
20051 ANSIfy.
20052 Remove `register' indications.
20053 Add plenty of `static'.
20054
20055 2001-12-27 Akim Demaille <akim@epita.fr>
20056
20057 * src/output.c (prepare): Drop the muscle `ntbase' which
20058 duplicates ntokens.
20059 * src/bison.simple: Formatting/comment changes.
20060 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
20061 is an undocumented synonym.
20062
20063 2001-12-22 Akim Demaille <akim@epita.fr>
20064
20065 * src/output.c (output_table_data): Change the prototype to use
20066 `int' for array ranges: some invocations do pass an int, not a
20067 short.
20068 Reported by Wayne Green.
20069
20070 2001-12-22 Akim Demaille <akim@epita.fr>
20071
20072 Some actions of web2c.y are improperly triggered.
20073 Reported by Mike Castle.
20074
20075 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
20076 * tests/regression.at (Web2c): Rename as...
20077 (Web2c Report): this.
20078 (Web2c Actions): New.
20079
20080 2001-12-22 Akim Demaille <akim@epita.fr>
20081
20082 Reductions in web2c.y are improperly reported.
20083 Reported by Mike Castle.
20084
20085 * src/conflicts.c (print_reductions): Fix.
20086 * tests/regression.at (Web2c): New.
20087
20088 2001-12-18 Akim Demaille <akim@epita.fr>
20089
20090 Some host fail on `assert (!"foo")', which expands to
20091 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
20092 Reported by Nelson Beebee.
20093
20094 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
20095 `#define it_succeeded 0' and `assert (it_succeeded)'.
20096
20097 2001-12-17 Marc Autret <autret_m@epita.fr>
20098
20099 * src/bison.simple: Don't hard code the skeleton line and filename.

20102
20103 2001-12-17 Paul Eggert <eggert@twinsun.com>
20104
20105 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
20106 YYDEBUG must be defined to a nonzero value.
20107
20108 * src/bison.simple (yytname): Do not assume that the user defines
20109 YYDEBUG to a properly parenthesized expression.
20110
20111 2001-12-17 Akim Demaille <akim@epita.fr>
20112
20113 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
20114 nlookaheads is a new member.
20115 Adjust all users.
20116 * src/lalr.h (nlookaheads): Remove this orphan declaration.
20117 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
20118 state.
20119
20120 2001-12-17 Akim Demaille <akim@epita.fr>

20122 * src/files.h, src/files.c (open_files, close_files): Remove.
20123 * src/main.c (main): Don't open/close files, nor invoke lex_free,
20124 let...

20136
20137 2001-12-17 Akim Demaille <akim@epita.fr>
20138
20139 * src/output.c (output_obstack): Be static and rename as...
20140 (format_obstack): this, to avoid any confusion with files.c's
20141 output_obstack.
20142 * src/reader.h (muscle_obstack): Move to...
20143 * src/output.h: here, since it's defined in output.c.
20144
20145 2001-12-17 Akim Demaille <akim@epita.fr>
20146
20147 * src/output.c (action_row, save_column, default_goto)
20148 (sort_actions, matching_state, pack_vector): Better variable
20149 locality.
20150

20163 2001-12-16 Marc Autret <autret_m@epita.fr>
20164
20165 * src/output.c (actions_output): Fix. When we use %no-lines,
20166 there is one less line per action.
20167
20168 2001-12-16 Marc Autret <autret_m@epita.fr>
20169
20170 * src/bison.simple: Remove a useless #line directive.
20171 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
20172 * src/output.c (get_lines_number): New.
20173 (output_parser): Adjust, now takes care about the lines of a
20174 output muscles.
20175 Fix line numbering.
20176 (actions_output): Computes the number of lines taken by actions.
20177 (output_master_parser): Insert new skeleton which is the name of
20178 the output parser file name.
20179
20180 2001-12-15 Marc Autret <autret_m@epita.fr>

20187
20188 2001-12-15 Akim Demaille <akim@epita.fr>
20189
20190 Make `make distcheck' work.
20191
20192 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
20193 system.h which uses libgettext.h.
20194
20195 2001-12-15 Akim Demaille <akim@epita.fr>
20196
20197 * src/nullable.c (set_nullable): Useless rules must be skipped,
20198 otherwise, since we range over their symbols, we might look at a
20199 nonterminal which no longer ``exists'', i.e., it is not counted in
20200 `nvars', hence we overflow our arrays.
20201
20202 2001-12-15 Akim Demaille <akim@epita.fr>
20203
20204 The header can also be produced directly, without any obstack!
20205 Yahoo!
20206
20207 * src/files.c, src/files.h (defines_obstack): Remove.
20208 (compute_header_macro): Global.
20209 (defines_obstack_save): Remove.
20210 * src/reader.c (parse_union_decl): No longer output to
20211 defines_obstack: its content can be found in the `stype' muscle
20212 anyway.
20213 (output_token_translations): Merge into...
20214 (symbols_output): this.
20215 Rename as...
20216 (symbols_save): this.
20217 (reader): Adjust.
20218 * src/output.c (header_output): New.
20219 (output): Call it.
20220
20221 2001-12-15 Akim Demaille <akim@epita.fr>
20222
20223 * src/reader.c (parse_union_decl): Instead of handling two obstack
20224 simultaneously, use one to define the `stype' muscle, and use the
20225 value of the latter to fill defines_obstack.
20226 (copy_comment): Remove.
20227 (copy_comment2): Work for a single obstack.
20228 Rename as...
20229 (copy_comment): this.
20230
20231 2001-12-15 Akim Demaille <akim@epita.fr>
20232
20233 * src/lex.c, src/lex.h (xgetc): No longer static.
20234 * src/reader.c (parse_union_decl): Revamp.
20235
20236 2001-12-15 Akim Demaille <akim@epita.fr>
20237
20238 Still making progress in separating Bison into (i) input, (ii)
20239 process, (iii) output: now we can directly output the parser file
20240 without using table_obstack at all.
20241
20242 * src/files.c, src/files.h (table_obstack): Bye bye.
20243 (parser_file_name): New.
20244 * src/files.c (compute_output_file_names): Compute it.
20245 * src/output.c (actions_output, output_parser)
20246 (output_master_parser): To a file instead of an obstack.
20247
20248 2001-12-15 Akim Demaille <akim@epita.fr>
20249
20250 Attach actions to rules, instead of pre-outputting them to
20251 actions_obstack.
20252
20253 * src/gram.h (rule_t): action and action_line are new members.
20254 * src/reader.c (symbol_list): Likewise.
20255 (copy_action): Save the actions within the rule.
20256 (packgram): Save them in rule_table.
20257 * src/output.c (actions_output): New.
20258 (output_parser): Use it on `%%actions'.
20259 (output_rule_data): Don't free rule_table.
20260 (output): Do it.
20261 (prepare): Don't save the `action' muscle.
20262 * src/bison.simple: s/%%action/%%actions/.
20263
20264 2001-12-15 Akim Demaille <akim@epita.fr>
20265
20266 * src/reader.c (copy_action): When --yacc, don't append a `;'
20267 to the user action: let it fail if lacking.
20268 Suggested by Arnold Robbins and Tom Tromey.
20269
20270 2001-12-14 Akim Demaille <akim@epita.fr>
20271
20272 * src/lex.c (literalchar): Simply return the char you decoded, non
20273 longer mess around with obstacks and int pointers.
20274 Adjust all callers.
20275
20276 2001-12-14 Akim Demaille <akim@epita.fr>
20277
20278 * src/lex.c (literalchar): Don't escape the special characters,
20279 just decode them, and keep them as char (before, eol was output as
20280 the 2 char string `\n' etc.).
20281 * src/output.c (output_rule_data): Use quotearg to output the
20282 token strings.
20283
20284 2001-12-13 Paul Eggert <eggert@twinsun.com>
20285
20286 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
20287 Do not infringe on the global user namespace when using C++.
20288 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
20289 All uses of `fprintf' and `stderr' changed.
20290
20291 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
20292
20293 2001-12-13 Akim Demaille <akim@epita.fr>
20294
20295 The computation of nullable is broken: it doesn't handle empty
20296 RHS's properly.
20297
20298 * tests/torture.at (GNU AWK Grammar): New.
20299 * tests/sets.at (Nullable): New.
20300 * src/nullable.c (set_nullable): Instead of blindly looping over
20301 `ritems', loop over the rules, and then over their rhs's.
20302
20303 Work around Autotest bugs.
20304
20305 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
20306 frame, because Autotest understand lines starting with a `+' as
20307 traces from the shell. Then, they are not processed properly.
20308 Admittedly an Autotest bug, but we don't have time to wait for
20309 Autotest to catch up.
20310 * tests/regression.at (Broken Closure): Adjust to the new table
20311 frames.
20312 Move to...
20313 * tests/sets.at: here.
20314
20315 2001-12-13 Akim Demaille <akim@epita.fr>
20316
20317 * src/closure.c (closure): Use nrules instead of playing tricks
20318 with BITS_PER_WORD.
20319
20320 2001-12-13 Akim Demaille <akim@epita.fr>
20321
20322 * src/print.c (print_actions): Output the handling of `$' as the
20323 traces do: shifting the token EOF. Before EOF was treated as a
20324 nonterminal.
20325 * tests/regression.at: Adjust some tests.
20326 * src/print_graph.c (print_core): Complete the set of items via
20327 closure. The next-to-final and final states are still unsatisfying,
20328 but that's to be addressed elsewhere.
20329 No longer output the rule numbers, but do output the state number.
20330 A single loop for the shifts + gotos is enough, but picked a
20331 distinct color for each.
20332 (print_graph): Initialize and finalize closure.
20333
20334 2001-12-13 Akim Demaille <akim@epita.fr>
20335
20336 * src/reader.c (readgram): Remove dead code, an strip useless
20337 braces.
20338 (get_type): Remove, unused.
20339
20340 2001-12-12 Akim Demaille <akim@epita.fr>
20341
20342 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
20343 on that of lib/error.c.
20344
20345 2001-12-12 Akim Demaille <akim@epita.fr>
20346
20347 Some hosts don't like `/' in includes.
20348
20349 * src/system.h: Include libgettext.h without qualifying the path.
20350 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
20351 $(top_srcdir).
20352
20353 2001-12-11 Marc Autret <autret_m@epita.fr>
20354
20355 * src/output.c (output_parser): Remove useless muscle.
20356
20357 2001-12-11 Marc Autret <autret_m@epita.fr>
20358
20359 * src/bison.simple: Remove #line just before %%epilogue. It
20360 is now handled in ...
20361 * src/reader.c (read_additionnal_code): Add the output of a
20362 #line for the epilogue.
20363
20364 2001-12-10 Marc Autret <autret_m@epita.fr>
20365
20366 * src/reader.c (copy_definition): Re-use CPP-outed code which
20367 replace precedent remove.
20368 * src/bison.simple: Remove #line before %%prologue because
20369 %%input-line is wrong at this time.
20370
20371 2001-12-10 Marc Autret <autret_m@epita.fr>
20372
20373 * src/reader.c (symbols_output): Clean up.
20374 * src/output.c (output_gram, output): Clean up.
20375
20376 2001-12-10 Akim Demaille <akim@epita.fr>
20377
20378 * src/lalr.c (initialize_lookaheads): New. Extracted from...
20379 * src/LR0.c (set_state_table): here.
20380 * src/lalr.c (lalr): Call it.
20381
20382 2001-12-10 Akim Demaille <akim@epita.fr>
20383
20384 * src/state.h (shifts): Remove the `number' member: shifts are
20385 attached to state, hence no longer need to be labelled with a
20386 state number.
20387
20388 2001-12-10 Akim Demaille <akim@epita.fr>
20389
20390 Now that states have a complete set of members, the linked list of
20391 shifts is useless: just fill directly the state's shifts member.
20392
20393 * src/state.h (shifts): Remove the `next' member.
20394 * src/LR0.c (first_state, last_state): Remove.
20395 Adjust the callers.
20396 (augment_automaton): Don't look for the shifts that must be added
20397 a shift on EOF: it is those of the state we looked for! But now,
20398 since shifts are attached, it is no longer needed to looking
20399 merely by its id: its number.
20400
20401 2001-12-10 Akim Demaille <akim@epita.fr>
20402
20403 * src/LR0.c (augment_automaton): Better variable locality.
20404 Remove an impossible branch: if there is a state corresponding to
20405 the start symbol being shifted, then there is shift for the start
20406 symbol from the initial state.
20407
20408 2001-12-10 Akim Demaille <akim@epita.fr>
20409
20410 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
20411 only when appropriate: when insert_start_shifting_state' is not
20412 invoked.
20413 * tests/regression.at (Rule Line Numbers): Adjust.
20414
20415 2001-12-10 Akim Demaille <akim@epita.fr>
20416
20417 * src/LR0.c (augment_automaton): Now that all states have shifts,
20418 merge the two cases addition shifts to the initial state.
20419
20420 2001-12-10 Akim Demaille <akim@epita.fr>
20421
20422 * src/lalr.c (set_state_table): Move to...
20423 * src/LR0.c: here.
20424 * src/lalr.c (lalr): Don't call it...
20425 * src/LR0.c (generate_states): do it.
20426 * src/LR0.h (first_state): Remove, only the table is used.
20427
20428 2001-12-10 Akim Demaille <akim@epita.fr>
20429
20430 * src/LR0.h (first_shift, first_reduction): Remove.
20431 * src/lalr.c: Don't use first_shift: find shifts through the
20432 states.
20433
20434 2001-12-10 Akim Demaille <akim@epita.fr>
20435
20436 * src/LR0.c: Attach shifts to states as soon as they are
20437 computed.
20438 * src/lalr.c (set_state_table): Instead of assigning shifts to
20439 state, just assert that the mapping was properly done.
20440
20441 2001-12-10 Akim Demaille <akim@epita.fr>
20442
20443 * src/LR0.c (insert_start_shift): Rename as...
20444 (insert_start_shifting_state): this.
20445 (insert_eof_shifting_state, insert_accepting_state): New.
20446 (augment_automaton): Adjust.
20447 Better locality of the variables.
20448 When looking if the start_symbol is shifted from the initial
20449 state, using `while (... symbol != start_symbol ...)' sounds
20450 better than `while (... symbol < start_symbol ...)': If fail
20451 to see how the order between symbols could be relevant!
20452
20453 2001-12-10 Akim Demaille <akim@epita.fr>
20454
20455 * src/getargs.h: Don't declare `spec_name_prefix' and
20456 `spec_file_prefix', declared by src/files.h.
20457 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
20458 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
20459 * src/output.c (prepare): Adjust.
20460 * src/reader.c (symbols_output): Likewise.
20461 * src/vmsgetargs.c: Vaguely adjust, but who cares?
20462
20463 2001-12-10 Akim Demaille <akim@epita.fr>
20464
20465 * src/muscle_tab.c (muscle_init): NULL is a better default than
20466 `"0"'.
20467
20468 2001-12-10 Akim Demaille <akim@epita.fr>
20469
20470 * src/reader.c (reader): Calling symbols_output once is enough.
20471
20472 2001-12-10 Akim Demaille <akim@epita.fr>
20473
20474 Now that states have a complete set of members, the linked list of
20475 reductions is useless: just fill directly the state's reductions
20476 member.
20477
20478 * src/state.h (struct reductions): Remove member `number' and
20479 `next'.
20480 * src/LR0.c (first_reduction, last_reduction): Remove.
20481 (save_reductions): Don't link the new reductions, store them in
20482 this_state.
20483 * src/lalr.c (set_state_table): No need to attach reductions to
20484 states, it's already done.
20485 * src/output.c (output_actions): No longer free the shifts, then
20486 the reductions, then the states: free all the states and their
20487 members.
20488
20489 2001-12-10 Akim Demaille <akim@epita.fr>
20490
20491 * src/options.c (OPTN, DRTV, BOTH): New.
20492 (option_table): Use them.
20493
20494 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
20495 the job of system.h.
20496 * src/options.c: Don't include stdio.h and xalloc.h for the same
20497 reasons.
20498
20499 2001-12-10 Akim Demaille <akim@epita.fr>
20500
20501 * src/output.c (output, prepare): Make sure the values of the
20502 muscles `action' and `prologue' are 0-terminated.
20503
20504 2001-12-10 Akim Demaille <akim@epita.fr>
20505
20506 Clean up GCC warnings.
20507
20508 * src/reader.c (copy_action): `buf' is not used.
20509 (parse_skel_decl): Be static.
20510 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
20511 * src/options.h (create_long_option_table): Have a real prototype.
20512 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
20513 (hash_delete_at): Return const void *.
20514 Adjust casts to preserve the const.
20515
20516 2001-12-10 Akim Demaille <akim@epita.fr>
20517
20518 * configure.in: Require 2.52g.
20519 M4 is not needed, but AUTOM4TE is.
20520 * m4/m4.m4: Remove.
20521 * tests/Makefile.am: Adjust.
20522
20523 2001-12-10 Akim Demaille <akim@epita.fr>
20524
20525 One structure for states is enough, even though theoretically
20526 there are LR(0) states and LALR(1) states.
20527
20528 * src/lalr.h (state_t): Remove.
20529 (state_table): Be state_t **, not state_t *.
20530 * src/state.h (core, CORE_ALLOC): Rename as...
20531 (state_t, STATE_ALLOC): this.
20532 Add the LALR(1) members: shifts, reductions, errs.
20533 * src/LR0.c (state_table): Rename as...
20534 (state_hash): this, to avoid name clashes with the global
20535 `state_table'.
20536 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
20537 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
20538
20539 2001-12-10 Akim Demaille <akim@epita.fr>
20540
20541 Bison dumps core on bash.y.
20542 Reported by Pascal Bart.
20543
20544 * src/warshall.c (bitmatrix_print): New.
20545 (TC): Use it.
20546 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
20547 j must be the outer loop.
20548 * tests/regression.at (Broken Closure): New.
20549
20550 2001-12-05 Akim Demaille <akim@epita.fr>
20551
20552 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
20553 its argument.
20554 Reported by Peter Hamorsky.
20555
20556 2001-12-05 Akim Demaille <akim@epita.fr>
20557
20558 * src/conflicts.c (err_table): Remove.
20559 (resolve_sr_conflict): Adjust.
20560 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
20561 Rename as...
20562 (state_t.reductions, state_t.shifts): this.
20563
20564 2001-12-05 Akim Demaille <akim@epita.fr>
20565
20566 * src/reduce.c (reduce_grammar_tables): No longer disable the
20567 removal of useless rules via CPP but via `if (0)', so that the
20568 compiler still check the code is valid.
20569 For instance, it should have noticed `rline' no longer exists: use
20570 the `line' member of rule_t.
20571 * src/gram.c (dummy, rline): Remove, unused.
20572
20573 2001-12-05 Akim Demaille <akim@epita.fr>
20574
20575 * src/output.c (pack_vector): Use assert, not berror.
20576 * src/main.c (berror): Remove, unused.
20577
20578 2001-12-05 Akim Demaille <akim@epita.fr>
20579
20580 New experimental feature: if --verbose --trace output all the
20581 items of a state, not only its kernel.
20582
20583 * src/print.c (print_core): If `trace_flag', then invoke closure
20584 before outputting the items of the state (print_core is no longer
20585 a correct name them).
20586 (print_results): Invoke new_closure/free_closure if needed.
20587
20588 2001-12-05 Akim Demaille <akim@epita.fr>
20589
20590 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
20591 * src/closure.c, src/closure.h (itemsetsize): Rename as...
20592 (nitemset): for consistency with the rest of the project.
20593
20594 2001-12-05 Akim Demaille <akim@epita.fr>
20595
20596 * src/closure.c (print_closure): Improve.
20597 (closure): Use it for printing input and output.
20598
20599 2001-12-05 Akim Demaille <akim@epita.fr>
20600
20601 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
20602 indexed by nonterminals.
20603
20604 2001-12-05 Akim Demaille <akim@epita.fr>
20605
20606 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
20607 what it was!).
20608 * src/warshall.h: Remove accidental duplication of the content.
20609
20610 2001-12-05 Akim Demaille <akim@epita.fr>
20611
20612 * src/closure.c (set_fderives): De-obfuscate.
20613
20614 2001-12-05 Akim Demaille <akim@epita.fr>
20615
20616 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
20617
20618 2001-12-05 Akim Demaille <akim@epita.fr>
20619
20620 * src/closure.c (set_firsts): De-obfuscate.
20621
20622 2001-12-05 Akim Demaille <akim@epita.fr>
20623
20624 * src/output.c (action_row): De-obfuscate
20625 using the good o' techniques: arrays not pointers, variable
20626 locality, BITISSET, RESETBIT etc.
20627
20628 2001-12-05 Akim Demaille <akim@epita.fr>
20629
20630 Pessimize the code to simplify it: from now on, all the states
20631 have a valid SHIFTS, which NSHIFTS is possibly 0.
20632
20633 * src/LR0.c (shifts_new): Be global and move to..
20634 * src/state.c, src/state.h: here.
20635 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
20636 * src/print_graph: Adjust.
20637
20638 2001-12-05 Akim Demaille <akim@epita.fr>
20639
20640 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
20641 * src/conflicts.c: Use it.
20642 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
20643 incorrectly ``simplified''.
20644
20645 2001-12-05 Akim Demaille <akim@epita.fr>
20646
20647 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
20648 using the good o' techniques: arrays not pointers, variable
20649 locality, BITISSET, RESETBIT etc.
20650
20651 2001-12-05 Akim Demaille <akim@epita.fr>
20652
20653 * src/state.h (SHIFT_SYMBOL): New.

20655
20656 2001-12-05 Akim Demaille <akim@epita.fr>
20657
20658 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
20659 (print_reductions): De-obfuscate using the good o' techniques:
20660 arrays not pointers, variable locality, BITISSET.
20661
20662 2001-12-05 Akim Demaille <akim@epita.fr>
20663
20664 * src/conflicts.c (print_reductions): Arrays, not pointers.
20665 Use BITISSET.
20666
20667 2001-12-05 Akim Demaille <akim@epita.fr>
20668
20669 * src/conflicts.c (print_reductions): Pessimize, but clarify.
20670
20671 2001-12-05 Akim Demaille <akim@epita.fr>
20672
20673 * src/conflicts.c (print_reductions): Improve variable locality.
20674
20675 2001-12-05 Akim Demaille <akim@epita.fr>
20676
20677 * src/conflicts.c (print_reductions): Pessimize, but clarify.
20678
20679 2001-12-05 Akim Demaille <akim@epita.fr>
20680
20681 * src/conflicts.c (print_reductions): Improve variable locality.
20682
20683 2001-12-05 Akim Demaille <akim@epita.fr>
20684

20687
20688 2001-12-05 Akim Demaille <akim@epita.fr>
20689
20690 * src/LR0.c (augment_automaton): Formatting changes.
20691 Better variable locality.
20692
20693 2001-12-05 Akim Demaille <akim@epita.fr>
20694
20695 * src/lalr.c (matrix_print): New.
20696 (transpose): Use it.
20697 Use arrays instead of pointers.
20698
20699 2001-12-05 Akim Demaille <akim@epita.fr>
20700
20701 * src/lalr.c (maxrhs): Move to...
20702 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
20703 * src/lalr.c (build_relations): Adjust.
20704
20705 2001-12-05 Akim Demaille <akim@epita.fr>
20706
20707 * src/lalr.c (transpose): Free the memory allocated to the
20708 argument, as it is replaced by the results by the unique caller.
20709 (build_relations): Merely invoke transpose: it handles the memory
20710 deallocation.
20711 Improve variable locality.
20712 Avoid variables used as mere abbreviations.
20713 (compute_lookaheads): Use arrays instead of pointers.
20714
20715 2001-12-05 Akim Demaille <akim@epita.fr>
20716
20717 * src/lalr.c (initialize_F): Improve variable locality.
20718 Avoid variables used as mere abbreviations.
20719
20720 2001-12-05 Akim Demaille <akim@epita.fr>
20721
20722 * src/derives.c (print_derives): Display the ruleno.
20723 * src/lalr.c (initialize_F, transpose): Better variable locality
20724 to improve readability.
20725 Avoid variables used as mere abbreviations.
20726
20727 2001-12-05 Akim Demaille <akim@epita.fr>
20728
20729 * src/lalr.c (traverse): Use arrays instead of pointers.
20730
20731 2001-12-05 Akim Demaille <akim@epita.fr>
20732
20733 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
20734 the handling of squeue.
20735 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
20736
20737 2001-12-05 Akim Demaille <akim@epita.fr>
20738
20739 Because useless nonterminals are now kept alive (instead of being
20740 `destroyed'), we now sometimes examine them, and store information
20741 related to them. Hence we need to know their number, and adjust
20742 memory allocations.
20743
20744 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
20745 static.
20746 * src/LR0.c (allocate_itemsets): The memory allocated to
20747 `symbol_count' was used for two different purpose: once to count
20748 the number of occurrences of each symbol, and later reassigned to
20749 `shift_symbol', containing the symbol that can be shifted from a
20750 given state.
20751 Deobfuscate, i.e., allocate, use and free `symbol_count' here
20752 only, and...
20753 (new_itemsets): Allocate `shift_symbol' here.
20754 (allocate_itemsets): symbol_count includes useless nonterminals.
20755 Make room for them.
20756 (free_storage): Use `free', not `XFREE', for pointers that cannot
20757 be null.
20758
20759 2001-12-05 Akim Demaille <akim@epita.fr>
20760
20761 * src/nullable.c (set_nullable): Deobfuscate the handling of
20762 ritem.
20763 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
20764
20765 2001-12-05 Akim Demaille <akim@epita.fr>
20766
20767 * src/gram.c, src/gram.h (ritem_print): New.
20768 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
20769 (This useless function was defined only to work around VMS linkers
20770 that can't handle compilation units with variables only).
20771 * src/reduce.c (dump_grammar): Use it to trace the construction of
20772 ritem.
20773
20774 2001-12-04 Paul Eggert <eggert@twinsun.com>
20775
20776 * src/bison.simple (union yyalloc): Change member names
20777 to be the same as the stack names.
20778 (yyparse): yyptr is now union yyalloc *, not char *.
20779 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
20780 and may generate better code on some machines.
20781 (yystpcpy): Use prototype if __STDC__ is defined, not just
20782 if __cplusplus is defined.
20783
20784 2001-11-30 Akim Demaille <akim@epita.fr>
20785
20786 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
20787 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
20788 Gettext doesn't compile cleanly, and dies with -Werror.
20789 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
20790 Include WARNING_CFLAGS here.
20791 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
20792 before being defined.
20793
20794 2001-11-27 Paul Eggert <eggert@twinsun.com>
20795
20796 * lib/quotearg.h (quotearg_n, quotearg_n_style):
20797 First arg is int, not unsigned.
20798 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
20799 (SIZE_MAX, UINT_MAX): New macros.
20800 (quotearg_n_options): Abort if N is negative.
20801 Avoid overflow check on hosts where size_t is 64 bits and int
20802 is 32 bits, as overflow is impossible there.
20803 Fix off-by-one typo that caused unnecessary reallocation.
20804
20805 2001-11-29 Paul Eggert <eggert@twinsun.com>
20806
20807 Name space cleanup in generated parser.

20809 * doc/bison.texinfo (Bison Parser): Discuss system headers
20810 and their effect on the user name space.
20811
20812 * src/bison.simple:
20813 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
20814 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
20815 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
20816
20817 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
20818 on user names when possible.
20819
20820 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
20821 Simplify test for whather <alloca.h> exists.
20822
20823 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
20824
20825 (<stdio.h>): Include if YYDEBUG.
20826
20827 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
20828 ! defined (yyoverflow) && ! defined (yymemcpy).
20829
20830 (yymemcpy, yyparse): Rename local variables as needed so that
20831 they all begin with 'yy'.
20832
20833 (yystrlen, yystpcpy): New functions.
20834
20835 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
20836 All uses changed.
20837
20838 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
20839 instead of relying on string.h functions. Use YYSTACK_ALLOC
20840 and YYSTACK_FREE instead of malloc and free.
20841
20842 2001-11-30 Akim Demaille <akim@epita.fr>
20843
20844 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
20845 before their first uses.
20846 (YYBISON, YYPURE): Move to the top of the output.
20847

20849
20850 * tests/reduce.at (Useless Nonterminals): Fix.
20851
20852 2001-11-30 Akim Demaille <akim@epita.fr>
20853
20854 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
20855 if body instead of `;' to pacify GCC's warnings.
20856
20857 2001-11-30 Akim Demaille <akim@epita.fr>
20858
20859 Instead of mapping the LHS of unused rules to -1, keep the LHS
20860 valid, but flag the rules as invalid.
20861
20862 * src/gram.h (rule_t): `useful' is a new member.
20863 * src/print.c (print_grammar): Adjust.
20864 * src/derives.c (set_derives): Likewise.
20865 * src/reader.c (packgram, reduce_output): Likewise.
20866 * src/reduce.c (reduce_grammar_tables): Likewise.

20872 * src/print.c (print_results, print_grammar): Likewise.
20873 * tests/regression.at (Rule Line Numbers)
20874 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
20875
20876 2001-11-30 Akim Demaille <akim@epita.fr>
20877
20878 * src/reduce.c (nonterminals_reduce): Instead of throwing away
20879 useless nonterminals, move them at the end of the symbol arrays.
20880 (reduce_output): Adjust.
20881 * tests/reduce.at (Useless Nonterminals): Adjust.
20882
20883 2001-11-30 Akim Demaille <akim@epita.fr>
20884
20885 * src/reduce.c: Various comment/formatting changes.
20886 (nonterminals_reduce): New, extracted from...
20887 (reduce_grammar_tables): here.
20888 (reduce_grammar): Call nonterminals_reduce.
20889
20890 2001-11-29 Paul Eggert <eggert@twinsun.com>
20891

20893 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
20894 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
20895 New macros.
20896 (union yyalloc): New type.
20897 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
20898 an arbitrary restriction on hosts where size_t is wider than int.
20899
20900 (yyparse): Don't dump core if alloca or malloc fails; instead, report
20901 a parser stack overflow. Allocate just one block of memory for all
20902 three stacks, instead of allocating three blocks; this typically is
20903 faster and reduces fragmentation.
20904
20905 Do not limit the number of items in the stack to a value that fits
20906 in 'int', as this is an arbitrary limit on hosts with 64-bit
20907 size_t and 32-bit int.
20908
20909 2001-11-29 Marc Autret <autret_m@epita.fr>

20947 2001-11-28 Marc Autret <autret_m@epita.fr>
20948
20949 * src/bison.simple: Fix debug.

20968
20969 * src/closure.c (closure): No longer optimize the special case
20970 where all the bits of `ruleset[r]' are set to 0, to make the code
20971 clearer.
20972
20973 2001-11-28 Akim Demaille <akim@epita.fr>
20974
20975 * src/closure.c (closure): `r' and `c' are new variables, used to
20976 de-obfuscate accesses to RULESET and CORE.

21056 2001-11-26 Akim Demaille <akim@epita.fr>
21057
21058 * src/LR0.c (allocate_itemsets): kernel_size contains ints, not

21062
21063 * src/complain.c, src/complain.h (error): Remove, provided by

21105
21106 2001-11-23 Akim Demaille <akim@epita.fr>
21107
21108 Attaching lineno to buckets is stupid, since only one copy of each

21237 handling of VCG syntax, in particular: use quotearg.

21334 * tests/calc.at, tests/output.at, tests/regression.at,
21335 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
21336 now the tests are run in private dirs, therefore AC_CLEANUP and

21339 use abs. path to find config.h.
21340 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

21346

21362 braces to pacify GCC's warnings for `if () if () {} else {}'.
21363 * src/lex.c (parse_percent_token): Replace equal_offset with
21364 arg_offset.

22765 * src/reader.c (read_declarations): Adjust.
22766 * src/files.c (open_files): Don't call `compute_base_names', don't
22767 compute `attrsfile' since they depend upon data which might be
22768 *in* the input file now.
22769 (output_files): Do it here.
22770 * src/output.c (output_headers): Document the fact that this patch

22873 2000-12-19 Akim Demaille <akim@epita.fr>
22874
22875 * src/files.c (open_files): Yipee! We no longer need all the code
22876 looking for `/tmp' since we have no tmp file.
22877
22878 2000-12-19 Akim Demaille <akim@epita.fr>
22879

22908 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
22909 prevents type checking.
22910 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
22911 cast the value to (void *): assigning a `foo *' to a `void *'
22912 variable is valid.
22913 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
22914 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
22915 append characters.

22959 argument `data' for consistency with the prototypes.
22960 Qualify it `const'.
22961 (obstack_copy, obstack_copy0): Rename the second argument as

22965 `const' their input argument (`data' or `address').
22966 Adjust the corresponding macros to include `const' in casts.
22967
22968 2000-11-03 Akim Demaille <akim@epita.fr>
22969
22970 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

22973
22974 2000-11-03 Akim Demaille <akim@epita.fr>
22975
22976 For some reason, this was not applied.
22977

22992 (output_files): this.
22993 Use `obstack_save'.
22994 * src/main.c (main): Don't use `atexit' to register `done', since
22995 it no longer has to remove tmp files, just call `output_files'
22996 when there are no errors.

22999

23067
23068 * src/reader.c (copy_comment2): Expect the input stream to be on
23069 the `/' which is suspected to open a comment, instead of being
23070 called after `//' or `/*' was read.
23071 (copy_comment, copy_definition, parse_union_decl, copy_action)
23072 (copy_guard): Adjust.
23073
23074 2000-10-16 Akim Demaille <akim@epita.fr>
23075
23076 * src/reader.c (parse_expect_decl): Use `skip_white_space' and
23077 `read_signed_integer'.
23078
23079 2000-10-16 Akim Demaille <akim@epita.fr>
23080
23081 * src/reader.c (copy_dollar): New function.

23099
23100 2000-10-04 Akim Demaille <akim@epita.fr>
23101
23102 When a literal string is used to define two different tokens,
23103 `bison -v' segfaults.
23104 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
23105
23106 * tests/regression.m4: New file.
23107 Include the core of the sample provided by Piotr Gackiewicz.

23109 properly.
23110
23111 2000-10-04 Akim Demaille <akim@epita.fr>
23112
23113 * src/reader.c (parse_expect_decl): Keep `count' within the size
23114 of `buffer'.
23115 From Neil Booth.
23116
23117 2000-10-02 Paul Eggert <eggert@twinsun.com>
23118
23119 * bison.s1 (yyparse): Assign the default value
23120 unconditionally, to avoid a GCC warning and make the parser a
23121 tad smaller.
23122
23123 2000-10-02 Akim Demaille <akim@epita.fr>
23124
23125 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
23126 options.
23127
23128 2000-10-02 Akim Demaille <akim@epita.fr>
23129
23130 * src/derives.c, src/print.c, src/reduce.c: To ease the
23131 translation, move some `\n' out of the translated strings.
23132
23133 2000-10-02 Akim Demaille <akim@epita.fr>
23134
23135 The location tracking mechanism is precious for parse error
23136 messages. Nevertheless, it is enabled only when `@n' is used in
23137 the grammar, which is a different issue (you can use it in error
23138 message, but not in the grammar per se). Therefore, there should
23139 be another means to enable it.
23140
23141 * src/getargs.c (getargs): Support `--locations'.
23142 (usage): Report it.
23143 * src/getargs.h (locationsflag): Export it.
23144 * src/lex.c (percent_table): Support `%locations'.
23145 * src/reader.c (yylsp_needed): Remove this variable, now replaced
23146 with `locationsflag'.
23147 * doc/bison.texinfo: Document `--locations' and `%locations'.
23148 Sort the options.
23149 * tests/calc.m4: Test it.
23150
23151 For regularity of the names, replace each
23152 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
23153 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
23154 In addition replace each `flag' with `_flag'.
23155
23156 2000-10-02 Akim Demaille <akim@epita.fr>
23157
23158 Also test parse error messages, including with YYERROR_VERBOSE.
23159
23160 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
23161 associative).
23162 Use it to check the computations.
23163 Use it to check `nonassoc' is honored.
23164 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
23165 `--yyerror-verbose'.
23166 (_AT_CHECK_CALC): Adjust to this option.
23167 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
23168
23169 2000-10-02 Akim Demaille <akim@epita.fr>
23170
23171 Test also `--verbose', `--defines' and `--name-prefix'. Testing
23172 the latter demonstrates a flaw in the handling of non debugging
23173 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
23174 was used in order to simplify:
23175
23176 #if YYDEBUG
23177 if (yydebug)
23178 {
23179 ...
23180 }
23181 #endif
23182
23183 into
23184
23185 if (yydebug)
23186 {
23187 ...
23188 }
23189
23190 unfortunately this leads to a CPP conflict when
23191 `--name-prefix=foo' is used since it produces `#define yydebug
23192 foodebug'.
23193
23194 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
23195 (YYDPRINTF): New macro.
23196 Spread its use.
23197 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
23198 the bison options.
23199 Also test `--verbose', `--defines' and `--name-prefix'.
23200
23201 2000-10-02 Akim Demaille <akim@epita.fr>
23202
23203 Improve the readability of the produced parsers.
23204
23205 * src/bison.s1: Formatting changes.
23206 Improve the comment related to the `$' mark.
23207 (yydefault): Don't fall through to `yyresume': `goto' there.
23208 * src/output.c (output_parser): When the `$' is met, skip the end
23209 of its line.
23210 New variable, `number_of_dollar_signs', to check there's exactly
23211 one `$' in the parser skeleton.
23212
23213 2000-10-02 Akim Demaille <akim@epita.fr>
23214
23215 * lib/xstrdup.c: New file, from the fileutils.
23216 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
23217 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
23218 instead of strlen + xmalloc + strcpy.
23219 * src/symtab.c (copys): Remove, use xstrdup instead.
23220
23221 2000-10-02 Akim Demaille <akim@epita.fr>
23222
23223 * src/gram.h (associativity): New enum type which replaces the
23224 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
23225 `right_assoc', `left_assoc' and `non_assoc'.
23226 Adjust all dependencies.
23227 * src/reader.c: Formatting changes.
23228 (LTYPESTR): Don't define it, use it as a literal in
23229 `reader_output_yylsp'.
23230 * src/symtab.h (symbol_class): New enum type which replaces the
23231 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
23232 `sunknown', `stoken and `snterm'.
23233
23234 2000-10-02 Akim Demaille <akim@epita.fr>
23235
23236 * src/getargs.c (fixed_outfiles): Rename as...
23237 (yaccflag): for consistency and accuracy.
23238 Adjust dependencies.
23239
23240 2000-10-02 Akim Demaille <akim@epita.fr>
23241
23242 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
23243 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
23244 difficult and introduced a lot of core dump. It turns out that
23245 Bison used an implementation of `xmalloc' based on `calloc', and
23246 at various places it does depend upon the initialization to 0. I
23247 have not tried to isolate the pertinent places, and all the former
23248 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
23249 someone should address this issue.
23250
23251 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
23252 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

23258 2000-10-02 Akim Demaille <akim@epita.fr>
23259
23260 Various anti-`extern in *.c' changes.
23261
23262 * src/system.h: Include `assert.h'.
23263
23264 2000-10-02 Akim Demaille <akim@epita.fr>
23265
23266 * src/state.h (nstates, final_state, first_state, first_shift)
23267 (first_reduction): Move their exportation from here...
23268 * src/LR0.h: to here.
23269 Adjust dependencies.

23283 * src/print.h: New file.
23284 Propagate its use.

23286 (verbose, terse): Replace with...
23287 (print_results): this new function.

23296 * src/conflicts.h: New file.
23297 Propagate its inclusion.
23298
23299 2000-10-02 Akim Demaille <akim@epita.fr>

23351
23352 `user_toknums' is output as a `short[]' in `output.c', while it is

23397 Don't define PARAMS.
23398 * src/system.h: Define PARAMS.

23401 definitions in config.h.
23402
23403 2000-09-20 Akim Demaille <akim@epita.fr>
23404

23619 Change the handling of @s so that they behave exactly like $s.
23620 There is now a pseudo variable @$ (readble and writable), location
23621 of the lhs of the rule (by default ranging from the location of
23622 the first symbol of the rhs, to the location of the last symbol,

23658 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

24337 declaration to allow a multi-character symbol as an alias.
24338 (parse_thong_decl): New function.

24349 Revised and use multiple warnxxx functions to avoid using VARARGS1.
24350 (read_declarations): Improve the error message for
24351 an invalid character. Do not abort.
24352 (read_declarations, copy_guard, copy_action): Use
24353 printable_version to avoid unprintable characters in printed output.

24377 (safegetc): New function to deal with EOF gracefully.
24378 (literalchar); new function to deal with reading \ escapes.
24379 (lex): Use literalchar.
24380 (lex): Implemented "..." tokens.
24381 (literalchar, lex, parse_percent_token): Made tokenbuffer
24382 always contain the token. This includes growing the token
24383 buffer while reading an integer.
24384 (parse_percent_token): Replaced if-else statement with percent_table.
24385 (parse_percent_token): Added % declarations as another
24386 way to specify the flags -n, -l, and -r. Also added hooks for
24387 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
24388 major changes to files.c.
24389 (lex) Retain in the incoming stream a character following
24390 an incorrect '/'.
24391 (skip_white_space, lex): Revised most error messages
