32
33 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.

58 line.
59
60 2004-10-22 Akim Demaille <akim@epita.fr>
61 and Paul Eggert <eggert@cs.ucla.edu>
62
63 Remove some arbitrary limits on goto numbers and relations.
64 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
65 initial values, since they're never used.
66 (set_goto_map): ngotos is now unsigned, so test for overflow
67 by seeing whether it wraps around to zero.
68 * src/lalr.h (goto_number): Now size_t, not short int.
69 (GOTO_NUMBER_MAXIMUM): Remove.
70 * src/relation.c (relation_print, traverse, relation_transpose):

74
75 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
76
77 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
78 keyword, not an identifier. Problem reported by Baron Schwartz in
79 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
80
81 2004-10-11 Akim Demaille <akim@epita.fr>
82
83 * src/symtab.c (symbol_check_alias_consistency): Also check
84 type names, destructors, and printers.
85 Reported by Alexandre Duret-Lutz.
86 Recode the handling of associativity and precedence in terms
87 of symbol_precedence_set.
88 Accept no redeclaration at all, not even equal to the previous
89 value.
90 (redeclaration): New.
91 Use it to factor redeclaration complaints.
92 (symbol_make_alias): Don't set the type of the alias, let
93 symbol_check_alias_consistency do it as for other features.
94 * src/symtab.h (symbol): Add new member prec_location, and
95 type_location.
96 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
97 * tests/input.at (Incompatible Aliases): New.
98
99 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
100
101 .cvsignore fixes to accommodate gnulib changes,
102 and the practice of naming build directories "_build".
103 * .cvsignore: Add "_*". Sort.
104 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
105 * m4/.cvsignore: Add "*_gl.m4".
106
107 2004-10-06 Akim Demaille <akim@epita.fr>
108
109 * src/parse-gram.y (add_param): Fix the truncation of trailing
110 spaces.
111
112 2004-10-05 Akim Demaille <akim@epita.fr>
113
114 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
115 whether the reducion was empty or not. This leaves room to
116 improve the use of YYLLOC_DEFAULT in such a case.
117 lalr1.cc is still experimental, so changing this is acceptable.
118 And finally, there are probably not many users who changed the
119 handling of locations in GLR, so changing is admissible too.
120
121 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
122 empty reduction, set @$ to an empty location ending the previously
123 stacked symbol.
124 Adjust uses to make sure the code is triggered on empty
125 reductions.
126 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
127 expected output: empty reductions have empty locations.
128
129 2004-09-29 Akim Demaille <akim@epita.fr>
130
131 * data/lalr1.cc: Move towards a more standard C++ coding style
132 for templates: Class < T > -> Class<T>.
133
134 2004-09-29 Akim Demaille <akim@epita.fr>
135
136 * data/lalr1.cc: Reinstall the former ctor, for sake of
137 compatibility, but warn it will be removed.
138 Move towards a more standard C++ coding style (i.e., type *var ->
139 type* var).
140
141 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
142
143 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
144 since it's less likely to work if NULs are involved in the future.
145
146 2004-09-27 Akim Demaille <akim@epita.fr>
147
148 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
149
150 2004-09-27 Akim Demaille <akim@epita.fr>
151
152 * data/lalr1.cc (b4_parse_param_decl_1): New.
153 (b4_parse_param_decl): Use it to have different names between attribute
154 and argument names.
155 (b4_cc_constructor_call): Likewise.
156
157 2004-09-24 Akim Demaille <akim@epita.fr>
158
159 * src/parse-gram.y (add_param): Strip the leading and trailing
160 blanks from a formal argument declaration.
161 (YY_LOCATION_PRINT): New.
162
163 2004-09-24 Akim Demaille <akim@epita.fr>
164
165 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
166 after the location.
167
168 2004-09-24 Akim Demaille <akim@epita.fr>
169
170 * doc/bison.texinfo (Table of Symbols): Sort.
171
172 2004-09-21 Akim Demaille <akim@epita.fr>
173
174 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
175 the useless parentheses.
176 Suggested by Paul Eggert.
177
178 2004-09-20 Akim Demaille <akim@epita.fr>
179
180 Let the initial-action act on the look-ahead, and use it for the
181 "initial push" (corresponding to an hypothetical beginning-of-file).
182 And let lalr1.cc honor %initial-action.
183
184 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
185 example.
186 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
187 (Parser::Parser): Remove the ctor that used to initialize it.
188 (Parser::parse): Like in the other skeletons, issue the "starting
189 parse" message before any action.
190 Honor %initial-action.
191 Initialize the stacks with the lookahead.
192 * data/yacc.c: Let $$ and @$ in %initial-action designate the
193 look-ahead.
194 Push them in the stacks.
195 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
196
197 2004-09-20 Akim Demaille <akim@epita.fr>
198
199 * doc/bison.texinfo (Initial Action Decl): New.
200
201 2004-09-20 Akim Demaille <akim@epita.fr>
202
203 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
204 clearer criterion to define it.
205 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
206 When reducing on an empty RHS, use the latest stacked location as
207 location.
208 yylloc is not always available.
209 * data/glr.c: Likewise.
210 Also, honor initial-actions.
211
212 2004-09-20 Akim Demaille <akim@epita.fr>
213
214 * data/yacc.c (YY_LOCATION_PRINT): New.
215 Define when we know YYLTYPE's structure, i.e., when the default
216 YYLLOC_DEFAULT is used.
217 * data/c.m4 (b4_yysymprint_generate): Use it.
218 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
219 value of the result.
220 (error_start_): Replace with...
221 (error_range_): this location array.
222 This allows to replace code relying on the implementation of
223 locations by portable code.
224 * data/yacc.c (yylerrsp): Replace with...
225 (yyerror_range): this.
226 Every time a token is popped, update yyerror_range[0], to have an
227 accurate location for the error token.
228 * data/glr.c (YY_LOCATION_PRINT): New.
229 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
230 deference a pointer.
231 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
232 report the location in %printers.
233
234 * src/scan-skel.l: Instead of abort, report error messages to ease
235 understanding skeleton scanning failures.
236
237 2004-09-16 Akim Demaille <akim@epita.fr>
238
239 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
240 (iterator, const_iterator): these, to be more in the C++ spirit.
241 Also, return reverse iterators so that when displaying the stack
242 we display its bottom first.
243 (Parser::stack_print_, Parser::reduce_print_): Match the messages
244 from yacc.c.
245 We should probably use vector here though.
246
247 2004-09-16 Akim Demaille <akim@epita.fr>
248
249 Have more complete shift traces.
250
251 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
252 to report Shifts instead of ad hoc YYDPRINTF invocations,
253 including for the error token.
254 * data/lalr1.cc (symprint_): Output the location.
255 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
256 output the location within the %printer.
257 Activate GLR tests, at least to make sure they compile properly.
258 They still don't pass though.
259 * tests/calc.at: Adjust expect verbose output, since now "Entering
260 state..." is on a different line than the "Shifting" message.
261
262 2004-09-08 Akim Demaille <akim@epita.fr>
263
264 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
265 Bison directive from the Bison file to the invocation of this
266 macro, so that these directives are passed to
267 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
268 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
269 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
270 the extra Bison directives instead of the whole series.
271 Change the grammar so that there are recoverable errors, and
272 unrecoverable errors. Now we can have the parser give up before
273 consuming the whole input. As a result we now can observe that
274 the lookahead is freed when needed.
275 Change the parser source to parse argv[1] instead of a hard coded
276 string.
277 Simplify yylex, and give a value and location to EOF.
278 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
279 passed directives already coded in the file.
280 Add some tests to check the location of "error".
281 For some tests, the C++ parser is correct, and not yacc.c.
282 For other tests, they provide different, but unsatisfying, values,
283 so keep the C++ value so that at least one parser is "correct"
284 according to the test suite.
285 (Actions after errors): Remove, this is subsumed by the
286 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
287
288 2004-09-06 Akim Demaille <akim@epita.fr>
289
290 * data/lalr1.cc: Adjust the indentation of the labels.
291 (Parser::pop): New.
292 Use it.
293
294 2004-09-06 Akim Demaille <akim@epita.fr>
295
296 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
297 argument, an informative message.
298 Call YY_SYMBOL_PRINT.
299 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
300 * data/lalr1.cc (destruct_): Likewise.
301 In addition, no longer depend on b4_yysymprint_generate and
302 b4_yydestruct_generate to generate these functions, do it "by
303 hand".
304
305 2004-09-03 Akim Demaille <akim@epita.fr>
306
307 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
308 invoked, yydestruct the lookahead.
309 * tests/calc.at (Calculator $1): Update the expected lengths of
310 traces: there is an added line for the discarded lookahead.
311 * doc/bison.texinfo (Destructor Decl): Some rewording.
312 Define "discarded" symbols.
313
314 2004-09-02 Akim Demaille <akim@epita.fr>
315
316 * data/lalr1.cc (translate_, destruct_): No reason to be static.
317
318 2004-09-02 Akim Demaille <akim@epita.fr>
319
320 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
321 (YYDSYMPRINTF): Rename as...
322 (YY_SYMBOL_PRINT): this.
323 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
324 two.
325 Use it instead of direct symprint_ calls.
326 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
327 one.
328
329 2004-09-02 Akim Demaille <akim@epita.fr>
330
331 * data/lalr1.cc (b4_yysymprint_generate): New.
332 (symprint_): New member function, defined when YYDEBUG.
333 Use it consistently instead of token/nterm debugging output by
334 hand.
335 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
336 %printer calls to use cdebug_ when using lalr1.cc.
337
338 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
339
340 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
341 with #ifdef YYDEBUG.
342
343 2004-08-26 Akim Demaille <akim@epita.fr>
344
345 * doc/bison.texinfo (Implementing Loops): Rename as...
346 (Implementing Gotos/Loops): this.
347
348 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
349
350 Adjust to latest gnulib.
351 * bootstrap (gnulib_modules): Add xalloc-die.
352 Set LC_ALL=C so that file names sort consistently.
353 Prefer the gnulib copies of gettext.m4, glibc21.m4,
354 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
355 uintmax_t.m4, ulonglong.m4.
356 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
357 po.m4 since we are now using _gl.m4 instead.
358
359 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
360
361 * src/scan-action.l: Remove. Scanning of semantic actions is
362 handled in scan-gram.l.
363
364 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
365
366 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
367
368 * src/location.h (struct): The file member is a uniqstr.
369 (equal_boundaries): Use UNIQSTR_EQ for comparison.
370
371 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
372
373 Fix bug with non-%union parsers that have printers or destructors,
374 which led to a Bison core dump. Reported by Peter Fales in
375 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
376
377 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
378 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
379 not to our own type.
380 * src/output.c (symbol_destructors_output, symbol_printers_output):
381 Don't assume %union.
382 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
383 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
384 UNION-FLAG. All callers changed.
385 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
386 Use type char, not unsigned int, when declaring an array of char;
387 this lets us remove a cast.
388 (Printers and Destructors): Add non-%union test cases.
389
390 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
391
392 * doc/bison.texinfo: Minor editorial changes, mostly to the new
393 GLR writeups. E.g., avoid frenchspacing and the future tense,
394 change "lookahead" to "look-ahead", and change "wrt" to "with
395 respect to".
396
397 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
398
399 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
400 New sections, split off from the GLR Parsers section. Put the new
401 Simple GLR Parser near the start of the GLR section, for clarity.
402 Rewrite connective text.
403
404 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
405
406 * doc/bison.texinfo (Simple GLR Parsers): New section.
407
408 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
409
410 * NEWS, TODO, doc/bison.texinfo:
411 Use "look-ahead" instead of "lookahead", to be consistent.
412 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
413 while we're fixing "look-ahead".
414 * src/conflicts.c (shift_set): Renamed from shiftset.
415 (look_ahead_set): Renamed from lookaheadset.
416 * src/print.c: Likewise.
417 * src/getargs.c (report_args): Add "look-ahead" as the new canonical
418 name for "lookahead".

420 * src/getargs.h (report_look_ahead_tokens): Renamed from
421 report_lookaheads.
422 * src/lalr.c (compute_look_ahead_tokens): Renamed from
423 compute_lookaheads.
424 (state_look_ahead_tokens_count): Renamed from state_lookaheads_count.
425 (look_ahead_tokens_print): Renamed from lookaheads_print.
426 * src/state.c (state_rule_look_ahead_tokens_print): Renamed from
427 state_rule_lookaheads_print.
428 * src/state.h: Likewise.
429 (reductions.look_ahead_tokens): Renamed from lookaheads.
430 * tests/torture.at (AT_DATA_LOOK_AHEAD_TOKENS_GRAMMAR): Renamed from

432
433 2004-06-03 Paul Eggert <eggert@cs.ucla.edu>
434
435 * README: Update location of patched M4 distribution.
436
437 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
438
439 Don't assume the C++ compiler takes the same arguments as the C compiler
440 (trivial change).
441 * configure.ac (O0CXXFLAGS): New var.
442 * tests/atlocal.in (CXXFLAGS): Use it.
443
444 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
445
446 Fix some "make check" problems with C++ reported by
447 Albert Chin-A-Young for Tru64 C++ in this thread:
448 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
449
450 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
451 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
452 Output to a .cc file for C++, not to a .c file.

454 * tests/regression.at (AT_CHECK_DANCER): Likewise.
455 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
456

460 C++ compiler. (trivial change)
461
462 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
463
464 Spent a few hours checking out which prerequisite versions the
465 current sources actually require. I went all the way back to
466 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
467 a seemingly endless set of combinations of versions more recent
468 than that. The bottom line is that the current sources require
469 fairly recent versions of the build tools, and it'll be some work
470 to change this.
471 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
472 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
473 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
474 Add comments explaining why those particular versions are
475 currently needed.
476
477 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
478 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
479 <http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
480
481 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
482 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
483
484 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
485
486 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
487 0.11.5. Suggested by Bruno Haible.
488 * bootstrap: Remove gettext version checking.
489
490 * doc/bison.texinfo (Decl Summary): Also mention that %union
491 can depend on prerequisite types. Problem reported by Tim
492 Van Holder.
493
494 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
495
496 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
497 * README-alpha: Don't tell people not to package this.
498
499 * bootstrap: Don't assume $(...) works; use `...` instead.
500 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
501 gettext better.
502
503 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
504 put into the -d output file, and mention what to do if YYSTYPE is
505 defined as a macro.
506
507 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
508
509 Undo change made earlier today: it caused autopoint to not bring
510 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
511 autopoint's.
512
513 * bootstrap: Check that gettext version matches what's in
514 configure.ac. Warn users to ignore robots.txt ERROR 404.
515 * bootstrap: Undo today's earlier change (logged below).
516 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
517
518 The gettext version checking is causing more trouble than it's
519 curing; remove it. Problem reported by Paul Hilfinger.
520
521 * bootstrap: Issue a warning that one can expect a message
522 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
523 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
524
525 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
526
527 Ensure that the C++ compiler used for testing actually works on a
528 simple test program; if not, skip the C++-related tests. Problem
529 reported by Vin Shelton in:
530 http://mail.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
531
532 * m4/cxx.m4: New file.
533 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
534 * tests/atlocal.in (BISON_CXX_WORKS): Add.
535 * tests/local.at (AT_COMPILE_CXX): Use it.
536
537 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
538
539 * data/glr.c (yylloc): Output this macro even if locations are not
540 being generated, as the GLR parser needs it even in that case.
541 Problem reported by Troy A. Johnson
542 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
543
544 * configure.ac (AC_INIT): Update to 1.875e.
545
546 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
547
548 * NEWS: Version 1.875d.
549 * configure.ac (AC_INIT): Likewise.
550 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
551
552 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
553 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
554 lalr1.cc runs afoul of the first, and the last two are no longer
555 supported by GCC 3.4.0.
556 * README: Mention GNU m4 1.4 or later; mention m4 patches.
557 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
558
559 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
560
561 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
562 unsigned int, for compatibility with latest gnulib hash module.

564 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
565 * src/uniqstr.c (hash_uniqstr): Likewise.
566
567 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
568
569 * NEWS: Unescaped newlines are no longer allowed in char & strings.
570
571 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
572 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
573 character and string literals.
574 (unexpected_end): New function.
575 (unexpected_eof): Use it.
576 (unexpected_newline): New function.
577 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
578 actions.
579
580 * NEWS: Document %expect-rr.
581
582 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
583 Fix typo by replacing $1 with $option.
584 Remove more 'intl'-related files.
585 Don't DEFUN AM_INTL_SUBDIR twice.
586
587 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
588 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
589 strtoul.c.
590 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
591 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
592 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
593 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
594 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
595 * src/.cvsignore: Add *.output.
596
597 * src/parse-gram.y: Put copyright notice inside %{ %} so it
598 gets copied to the output file.
599
600 2004-04-28 Paul Eggert <eggert@twinsun.com>
601
602 Get files from the gnulib and po repositories, instead of relying
603 on them being in our CVS. Upgrade to latest versions of gnulib
604 and Automake.
605
606 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
607 * bootstrap: Bootstrap from gnulib and po repositories.
608 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
609 * README-cvs: Document these changes. Remove version numbers from
610 mentions of build tools, since they change so often. Mention Flex.
611
612 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
613 (gl_USE_SYSTEM_EXTENSIONS): Add.
614 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
615 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
616 does this for us.
617 (AC_ISC_POSIX): Remove; we no longer support this
618 ancient OS, as it gets in the way of latest Autoconf & gnulib.
619 (AC_HEADER_STDC): Remove: we now assume C89 or better.
620 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
621 Do not check for C89 headers, except for locale.h which is used
622 by the Yacc library and must port to K&R hosts.
623 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
624 Do not check for C89 functions, except for setlocale which is
625 used by the Yacc library.
626 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
627 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
628 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,
629 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE,
630 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
631 AM_GNU_GETTEXT): Remove; now done by:
632 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
633 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
634 for us.
635
636 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
637 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
638 Define to empty, as gnulib.mk will do the rest for us.
639 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
640 for us.
641 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
642 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
643
644 * src/files.c: Include gnulib's xstrndup.h.
645
646 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
647 (REALLOC): Use xnrealloc, for likewise.
648 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
649 (strnlen, memrchr): Remove decls; functions no longer used.
650 Include <stpcpy.h>.
651
652 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

672 po/pt_BR.po, po/ro.po, po/ru.po, po/sv.po, po/tr.po:
673 Remove, as these files are now generated automatically
674 by bootstrap or automake.
675
676 * po/ChangeLog: Remove: all but one entry was a duplicate
677 of this file, and I moved that 2000-11-02 entry here.
678
679 * config/.cvsignore: Add Makefile, depcomp, install-sh.
680 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,
681 argmatch.h, basename.c, dirname.c, dirname.h, error.c, error.h,

690 xstrndup.h.
691 * m4/.cvsignore: Remove Makefile, Makefile.in. Add alloca.m4,
692 dirname.m4, dos.m4, error.m4, getopt.m4, hash.m4, mbrtowc.m4,
693 mbswidth.m4, obstack.m4, onceonly.m4, quote.m4, quotearg.m4,
694 stdbool.m4, stpcpy.m4, strnlen.m4, unlocked-io.m4, xalloc.m4.
695 * po/.cvsignore: Add *.po, LINGUAS, Makefile.in.in, Makevars.
696 * src/.cvsignore: Remove *_.c.
697
698
699 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
700 support it. (The latest stable gzip doesn't.)
701
702 2004-04-27 Paul Eggert <eggert@twinsun.com>
703
704 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
705 case, as stos_ is now used by destructors due to the 2004-02-09
706 change.
707
708 Remove more K&R C support.
709 * lib/libiberty.y (PARAMS): Remove. All uses removed.
710 * lib/subpipe.c (errno): Remove decl.
711 Include <stdlib.h> unconditionally.
712 (EXIT_FAILURE): Remove macro.
713 * src/complain.c (vfprintf, strerror): Remove.
714 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
715 unconditionally.
716 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
717 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
718 (strchr, strspn, memchr): Remove decls.
719 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
720 unconditionally. Do not declare perror.
721 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
722 unconditionally.
723
724 * src/complain.c (_): Remove useless defn, as system.h defines this.
725
726 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
727 with latest obstack.h.
728 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
729 to procedure types, as obstack.h now does that for us.
730 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
731
732 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
733 so that this include file can stand alone.
734 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
735 does this now. Include subpipe.h first after config.h, to
736 test whether it can stand alone.
737
738 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
739 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
740 unused declaration.
741
742 * tests/synclines.at (%union synch line): Put a dummy member in
743 the union, because empty unions aren't allowed in C. Caught
744 by GCC 3.4.0.
745
746 2004-04-13 Jim Meyering <jim@meyering.net>
747
748 * src/conflicts.c (conflicts_print): Correct format string typo:
749 use `%%' to produce literal `%'. (trivial change)
750
751 2004-03-30 Paul Eggert <eggert@twinsun.com>
752
753 * src/getargs.c (version): Update copyright year to 2004.
754
755 * data/c.m4 (b4_int_type): Use 'short int' rather than
756 'short', and similarly for 'long', 'unsigned', etc.
757 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
758 yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,
759 yy_yypstack, yydumpstack): Likewise.
760 * data/lalr1.cc (user_token_number_max_, user_token_number_max_,
761 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):

776 * src/lalr.h (goto_number): Likewise.
777 * src/nullable.c (nullable_compute): Likewise.
778 * src/output.c (prepare_rules): Likewise.
779 * src/relation.c (relation_print, relation_digraph): Likewise.
780 * src/relation.h (relation_node): Likewise.
781 * src/state.h (state_number, transitions, errs, reductions,
782 struct state): Likewise.
783 * src/symtab.h (symbol_number, struct symbol): Likewise.
784 * src/tables.c (vector_number, tally, action_number,
785 default_goto, goto_actions): Likewise.
786 * tests/existing.at (GNU Cim Grammar): Likewise.
787 * tests/regression.at (Web2c Actions): Likewise.
788
789 * src/output.c (muscle_insert_short_int_table): Renamed from
790 muscle_insert_short_table. All uses changed.
791
792 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
793
794 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
795 (declaration): Replace expected_conflicts with expected_sr_conflicts.
796 Add %expect-rr rule.
797
798 * src/scan-gram.l: Recognize %expect-rr.
799
800 * src/conflicts.h (expected_sr_conflicts): Rename from
801 expected_conflicts.
802 (expected_rr_conflicts): Declare.
803
804 * src/conflicts.c (expected_sr_conflicts): Rename from
805 expected_conflicts.
806 (expected_rr_conflicts): Define.
807 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
808 for GLR parsers.
809 Use expected_sr_conflicts in place of expected_conflicts.
810 Warn if expected_rr_conflicts used in non-GLR parser.
811
812 * doc/bison.texinfo: Add documentation for %expect-rr.
813
814 2004-03-08 Paul Eggert <eggert@gnu.org>
815
816 Add support for hex token numbers. Suggested by Odd Arild Olsen in
817 <http://mail.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
818
819 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
820 in lalr1.cc.
821 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
822 * src/scan-gram.l (scan_integer): New function.
823 ({int}): Use it.
824 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
825 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
826 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
827 Say "long int", not "long", for uniformity with GNU style.
828
829 2004-02-25 Paul Eggert <eggert@twinsun.com>
830
831 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
832 compilers. This fixes a problem with Intel's C++ compiler being
833 chatty, reported by Guido Trentalancia in
834 <http://mail.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
835
836 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
837
838 Support %destructor and merge error locations in lalr1.cc.
839
840 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
841 (Parser::stos_): Define unconditionally.
842 (Parser::destruct_): New method. Generate its body with
843 b4_yydestruct_generate.
844 (Parser::error_start_): New attribute.
845 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
846 token which are discarded.
847 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
848 error_start_ when erroneous token are discarded.
849 (Parser::parse) <yyerrlab1>: Compute the location of the error
850 token so that it covers all the discarded tokens.
851 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
852 it can be called with `%skeleton "lalr1.cc"', and do that.
853
854 2004-02-02 Paul Eggert <eggert@twinsun.com>
855
856 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
857 $(top_srcdir)/lib and ../lib. This fixes a bug reported
858 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
859 There's no need to mention top_builddir since Automake does that
860 for us.
861 (INCLUDES): Remove, as Automake says it's obsolescent.
862 Contents migrated into AM_CPPFLAGS as described above.
863 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
864
865 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
866
867 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
868 (yyreportSyntaxError): Handle case where lookahead token is
869 YYEMPTY.
870
871 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
872
873 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
874 resulting parsers are compilable with C++.
875
876 2003-12-23 Paul Eggert <eggert@twinsun.com>
877
878 * config/depcomp, config/install-sh: Sync with Automake 1.8.
879 * src/output.c (output_skeleton): Rename local var.
880 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
881 Bison tokens, as this runs afoul of the 2003-10-07 change that
882 disallowed NUL bytes in character constants or string literals.
883
884 * tests/local.at: Require Autoconf 2.59's Autotest.
885 * tests/testsuite.at: Don't include local.at, since we now assume
886 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
887 including it.
888 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
889 multiple inclusion warnings.
890
891 2003-12-02 Akim Demaille <akim@epita.fr>
892

900
901 2003-10-07 Paul Eggert <eggert@twinsun.com>
902
903 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
904 if testsuite doesn't exist.
905
906 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
907 literals, unfortunately.
908 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
909 Complain about NUL bytes in character constants or string literals.
910
911 2003-10-05 Paul Eggert <eggert@twinsun.com>
912
913 * NEWS: Don't document %no-default-prec, as it's still
914 too experimental.
915 * doc/bison.texinfo: Document %no-default-prec only if
916 the defaultprec flag is set. Normally it's not.
917
918 2003-10-04 Paul Eggert <eggert@twinsun.com>
919
920 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
921 non-modifiable lvalue, instead of a modifiable one.
922 * doc/bison.texinfo (Actions): Document that $$ can
923 be assigned to. Do not claim that $$ and $N are
924 array element references: user code should not rely on this.
925
926 2003-10-01 Paul Eggert <eggert@twinsun.com>
927
928 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.

932 * NEWS, doc/bison.texinfo: Document the above.
933
934 2003-10-01 Akim Demaille <akim@epita.fr>
935
936 VCG no longer supports long_straight_phase.
937
938 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
939 * src/print_graph.c (print_graph): Adjust.
940
941 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
942 and Paul Eggert <eggert@twinsun.com>

954
955 2003-09-30 Paul Eggert <eggert@twinsun.com>
956
957 * tests/testsuite.at: Include local.at, not input.at, fixing
958 a typo in the 2003-08-25 patch.
959
960 2003-08-27 Akim Demaille <akim@epita.fr>
961
962 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
963 GCC warnings.
964
965 2003-08-26 Akim Demaille <akim@epita.fr>
966
967 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
968 "<\#" to avoid magic from Gnus when posting parts of this script.
969
970 2003-08-26 Akim Demaille <akim@epita.fr>
971
972 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
973 (Parser::parse): here.
974 Adjust: nerrs and errstatus is now replaced by...
975 (Parser::nerrs_, Parser::errstatus_): New.
976
977 2003-08-25 Akim Demaille <akim@epita.fr>
978
979 * config/announce-gen, Makefile.cfg: New.
980 * Makefile.am: Adjust.

982 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
983
984 2003-08-25 Akim Demaille <akim@epita.fr>
985
986 When reducing initial empty rules, Bison parser read an initial
987 location that is not defined. This results in garbage, and that
988 affects Bison's own parser. Therefore we need (i) to extend Bison
989 to support a means to initialize this location, and (ii) to use
990 this CVS Bison to fix CVS Bison's parser.
991
992 * src/reader.h, reader.c (epilogue_augment): Remove, replace
993 with...
994 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
995 * src/parse-gram.y: Adjust.
996 (%initial-action): New.
997 (%error-verbose): Since we require CVS Bison, there is no reason
998 not to use it.
999 * src/scan-gram.l: Adjust.
1000 * src/Makefile.am (YACC): New, to make sure we use our own parser.
1001 * data/yacc.c (yyparse): Use b4_initial_action.
1002
1003 2003-08-25 Akim Demaille <akim@epita.fr>
1004
1005 * doc/bison.texinfo: Don't promote stdout for error messages.
1006
1007 2003-08-25 Akim Demaille <akim@epita.fr>
1008
1009 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
1010 From Alexandre Duret-Lutz.
1011
1012 2003-08-25 Akim Demaille <akim@epita.fr>

1014 Version 1.875c.
1015
1016 2003-08-25 Akim Demaille <akim@epita.fr>
1017
1018 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
1019 Use them.
1020
1021 2003-08-25 Akim Demaille <akim@epita.fr>
1022
1023 * data/lalr1.cc (Parser::reduce_print_): New.
1024 Use it.
1025
1026 2003-08-25 Akim Demaille <akim@epita.fr>
1027
1028 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
1029 error recovery loops. This patch is based on
1030 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
1031 Also, augment the similarity between lalr1.cc and yacc.c.
1032 Note: the locations of error recovery rules are not correct yet.
1033
1034 * data/lalr1.cc: Comment changes to augment the similarity between
1035 lalr1.cc and yacc.c.
1036 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
1037 (yyerrlab1): Remove, but where it used to be (now the bottom part of
1038 yyerrlab), when hitting EOF, pop the whole stack here instead of
1039 merely falling thru the default error handling mechanism.
1040 (yyerrorlab): New label, with the old contents of YYERROR,
1041 plus the following change: pop the stack of rhs corresponding
1042 to the production that invoked YYERROR. That is how Yacc
1043 behaves (required by POSIX).
1044 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
1045 fail.
1046
1047 2003-08-25 Akim Demaille <akim@epita.fr>
1048
1049 Tune local.at so that people can "autom4te -l autotest calc.at -o
1050 calc" for instance, to extract a sub test suite.
1051
1052 * tests/testsuite.at: Move the initialization, Autotest version
1053 requirement, and AT_TESTED invocation into...
1054 * tests/local.at: here.
1055 * tests/testsuite.at: Include it for compatibility with Autoconf
1056 2.57.
1057 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
1058 be ignore.
1059
1060 2003-08-04 Paul Eggert <eggert@twinsun.com>
1061
1062 Rework code slightly to avoid gcc -Wtraditional warnings.
1063 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
1064 The returned value is now stored in *YY0. All callers changed.
1065 * src/output.c (merge_output): Adjust to the above change.
1066
1067 2003-07-26 Paul Eggert <eggert@twinsun.com>
1068
1069 * data/glr.c (YYASSERT): New macro.
1070 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
1071 yyresolveStates, yyprocessOneStack):
1072 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
1073 Derived from a suggestion by Frank Heckenbach.
1074
1075 2003-07-25 Paul Eggert <eggert@twinsun.com>
1076
1077 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
1078 for portability to K&R C (after ansi2knr, presumably). See
1079 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
1080 by Frank Heckenbach, though I have omitted the structure-initialization
1081 part of his glr-knr.diff patch since I recall that the Portable
1082 C Compiler didn't require that change.
1083
1084 Let the user specify how to allocate and free memory.
1085 Derived from a suggestion by Frank Heckenbach in
1086 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
1087 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
1088 All uses of free, malloc, realloc changed to use these macros,
1089 and unnecessary casts removed.
1090 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
1091
1092 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
1093
1094 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
1095 use s.empty() rather than s == "" to test for empty string; see
1096 <http://mail.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
1097 (trivial change)
1098
1099 2003-06-25 Akim Demaille <akim@epita.fr>
1100
1101 * config/depcomp, config/install-sh: Update from masters.
1102
1103 2003-06-20 Paul Eggert <eggert@twinsun.com>
1104
1105 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
1106 and return properly parenthesized result.
1107 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
1108 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
1109 Remove unnecessary parentheses from uses.
1110 * doc/bison.texinfo (Location Default Action): Describe the
1111 conventions for parentheses.
1112
1113 2003-06-19 Paul Eggert <eggert@twinsun.com>
1114
1115 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
1116 yyreportTree): Do not assume that size_t is the same width as int,
1117 when printing sizes. Print sizes using an unsigned format.
1118 Problem reported by Frank Heckenbach in
1119 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
1120
1121 Port to Forte Developer 7 C compiler.
1122 * data/glr.c (struct YYLTYPE): If locations are not being used,
1123 declare a single dummy member, as empty structs do not conform
1124 to the C standard.
1125 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
1126 the Forte Developer 7 C compiler complains that end-of-loop
1127 code is not reached.
1128
1129 2003-06-17 Paul Eggert <eggert@twinsun.com>
1130
1131 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
1132 avoid warnings from picky compilers about redefinition of PARAMS.
1133
1134 2003-06-17 Paul Eggert <eggert@twinsun.com>
1135
1136 Version 1.875b.
1137
1138 * NEWS: Document 1.875b.
1139
1140 * lib/bbitset.h: Do not include config.h; that's the includer's job.
1141 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
1142 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
1143 Don't use 'index' in comments, as it's a builtin fn on some hosts.
1144 * lib/bitset_stats.c: Include gettext.h unconditionally, as
1145 per recent gettext manual's suggestion.
1146 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
1147 Use prototypes, not old-style definitions.
1148 * lib/lbitset.c (lbitset_unused_clear): Likewise.
1149 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
1150 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
1151 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

1154 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
1155 vbitset_or_and_cmp, vbitset_copy): Likewise.
1156
1157 * lib/libiberty.h: Do not include config.h; that's the includer's job.

1159 (PARAMS): Define unconditionally for C89.
1160 (ATTRIBUTE_NORETURN): Remove.
1161 (ATTRIBUTE_UNUSED): Define unconditionally.
1162
1163 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
1164 <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>

1167 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
1168 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
1169 from libbitset.
1170
1171 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
1172 `How Can I Reset @code{yyparse}', since texinfo does not allow
1173 arbitrary @ in node names.
1174
1175 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
1176 shouldn't be needed according to the gettext 0.12.1 documentation
1177 but which seem to be needed anyway: codeset.m4 glibc21.m4
1178 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
1179 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

1184
1185 Upgrade to CVS gnulib.
1186 * stdbool_.h: File renamed from stdbool.h.in.
1187 * configure.ac (AM_STDBOOL_H): Invoke this instead of
1188 AC_HEADER_STDBOOL.
1189 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
1190 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.

1196 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
1197 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
1198 m4/quote.m4: Upgrade to today's gnulib.
1199
1200 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
1201 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
1202 the tests right now.
1203 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
1204 yyerror are declared before use; C99 requires this.
1205
1206 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1207
1208 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
1209 first.
1210 (yyrecoverSyntaxError): Correct the logic for setting and testing
1211 yyerrState.
1212 Correct comment on handling EOF.
1213 Allow states with only a default reduction, rather than failing
1214 (I can't quite reconstruct why these were not allowed before).
1215
1216 Fixes to avoid problem that $-N rules in GLR parsers can cause
1217 buffer overruns, corrupting state.
1218
1219 * src/output.c (prepare_rules): Output max_left_semantic_context
1220 definition.
1221 * src/reader.h (max_left_semantic_context): New variable declaration.
1222 * src/scan-gram.l (max_left_semantic_context): Define.
1223 (handle_action_dollar): Update max_left_semantic_context.
1224 * data/glr.c (YYMAXLEFT): New definition.
1225 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
1226 (yyresolveAction): Ditto.
1227
1228 Fixes to problems with location handling in GLR parsers reported by
1229 Frank Heckenbach (2003/06/05).
1230
1231 * data/glr.c (YYLTYPE): Make trivial if locations not used.
1232 (YYRHSLOC): Add parentheses, and define only if locations used.
1233 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
1234 locations not used.
1235 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
1236 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
1237
1238 * tests/cxx-type.at: Exercise location information; update tests
1239 to differentiate output with and without locations.
1240 Remove forward declarations of yylex and yyerror---caused errors
1241 because default YYLTYPE not yet defined.
1242 Change semantic actions to compute strings, rather than printing
1243 them directly (to test proper passing of semantics values). Change
1244 output to prefix notation and update test data and expected results.
1245 (yylex): Track locations.
1246 (stmtMerge): Return value rather than printing, and include arguments
1247 in value.
1248
1249 2003-06-03 Paul Eggert <eggert@twinsun.com>
1250
1251 Avoid warnings generated by GCC 2.95.4 when Bison is
1252 configured with --enable-gcc-warnings.
1253 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
1254 yy::]b4_parser_class_name[::translate_,
1255 yy::Stack::operator[] (unsigned),
1256 yy::Stack::operator[] (unsigned) const,
1257 yy::Slice::operator[] (unsigned),
1258 yy::Slice::operator[] (unsigned) const):
1259 Rename local vars to avoid warnings.
1260 * tests/glr-regression.at (Improper handling of embedded actions
1261 and $-N in GLR parsers): Remove unused local variable from yylex.
1262 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
1263 (void) as arg when not pure, since we now assume C89 when building
1264 Bison. Pacify GCC by using parameter.
1265
1266 2003-06-02 Paul Eggert <eggert@twinsun.com>
1267
1268 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
1269 yy::Location::lines, yy::Location::columns): Rename arguments
1270 to avoid shadowing; this removes a warning generated by GCC 3.3.
1271
1272 2003-06-01 Paul Eggert <eggert@twinsun.com>
1273
1274 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
1275 to g++, as GCC 3.3 complains if you do it.
1276 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
1277 everything that WARNING_CFLAGS has, except omit warnings
1278 not suitable for C++.
1279 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
1280 * tests/atlocal.in (CXXFLAGS): New var.
1281 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
1282
1283 Fix a GLR parser bug I reported in February; see
1284 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
1285 The problem was that GLR parsers did not conform to the C standard,
1286 because actions like { $1 = $2 + $3; } expanded to expressions
1287 that invoked YYFILL in separate subexpressions, and YYFILL assigned
1288 to a local variable. The C standard says that expressions
1289 like (var = f ()) + (var = f ()) have undefined behavior.
1290 Another problem was that GCC sometimes issues warnings that
1291 yyfill and its parameters are unused.
1292
1293 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
1294 as possibly unused.
1295 (yyfill): New function.
1296 (YYFILL): Use it.
1297 (yyuserAction): Change type of yynormal to bool, so that it matches
1298 the new yyfill signature. Mark it as possibly unused.
1299
1300
1301 Follow up on a bug I reported in February, where a Bison-generated
1302 parser can loop. Provide a test case and a fix for yacc.c. I
1303 don't have a fix for lalr1.cc or for glr.c, unfortunately.
1304 The original bug report is in:
1305 <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
1306
1307 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
1308 macro's size was becoming unwieldy.
1309 (yyerrlab): Do not discard an empty lookahead symbol, as this
1310 might destroy garbage.
1311 (yyerrorlab): New label, with the old contents of YYERROR,
1312 plus the following change: pop the stack of rhs corresponding
1313 to the production that invoked YYERROR. That is how Yacc
1314 behaves, and POSIX requires this behavior.
1315 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
1316 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
1317 Define 'alarm' to do nothing if unistd.h is not available.
1318 Add a new rule "exp: '-' error;" to test the above change to
1319 data/yacc.c. Use 'alarm' to abort any test taking longer than
1320 10 seconds, as it's probably looping.
1321 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
1322 Also, the new yacc.c generates two fewer diagnostics for an
1323 existing test.
1324
1325 2003-05-24 Paul Eggert <eggert@twinsun.com>
1326
1327 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
1328 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
1329 This fixes a problem reported by John Bowman when the Compaq/HP
1330 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
1331 -ansi -Wall -gall).
1332 * data/yacc.c (union yyalloc): Likewise.
1333 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
1334
1335 Switch from 'int' to 'bool' where that makes sense.

1340 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
1341 Return or accept bool, not int. All callers changed.
1342 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
1343 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

1345 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
1346 bitset_or_and_cmp_): Likewise.
1347 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
1348 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
1349 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
1350 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
1351 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
1352 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
1353 bitset_stats_or_and_cmp): Likewise.
1354 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
1355 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
1356 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
1357 ebitset_xor_cmp): Likewise.
1358 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
1359 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
1360 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
1361 lbitset_xor_cmp): Likewise.
1362 * lib/bbitset.h: Include <stdbool.h>.
1363 (struct bitset_vtable): The following members now return bool, not
1364 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
1365 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
1366 or_and_cmp).
1367 * src/conflicts.c (count_rr_conflicts): Likewise.
1368 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
1369 All uses changed.
1370 * lib/ebitset.c (ebitset_obstack_init): Likewise.
1371 * lib/lbitset.c (lbitset_obstack_init): Likewise.
1372 * src/getargs.c (debug_flag, defines_flag, locations_flag,
1373 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
1374 graph_flag): Likewise.
1375 * src/getargs.h (debug_flag, defines_flag, locations_flag,
1376 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
1377 graph_flag): Likewise.
1378 * src/output.c (error_verbose): Likewise.
1379 * src/output.h (error_verbose): Likewise.
1380 * src/reader.c (start_flag, typed): Likewise.
1381 * src/reader.h (typed): Likewise.
1382 * src/getargs.c (LOCATIONS_OPTION): New constant.
1383 (long_options, getargs): Use it.
1384 * src/lalr.c (build_relations): Use bool, not int.
1385 * src/nullable.c (nullable_compute): Likewise.
1386 * src/print.c (print_reductions): Likewise.
1387 * src/tables.c (action_row, pack_vector): Likewise.
1388 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
1389 * src/output.c (prepare): Use it.
1390 * src/output.c (token_definitions_output,
1391 symbol_destructors_output, symbol_destructors_output): Use string,
1392 not boolean integer, to keep track of whether to output separator.
1393 * src/print_graph.c (print_core): Likewise.
1394 * src/state.c (state_rule_lookaheads_print): Likewise.
1395
1396 * config/install-sh: Sync from automake 1.7.5.
1397
1398 2003-05-14 Paul Eggert <eggert@twinsun.com>
1399
1400 * src/parse-gram.y (rules_or_grammar_declaration): Require a
1401 semicolon after a grammar declaration, in the interest of possible
1402 future changes to the Bison input language.
1403 Do not allow a stray semicolon at the start of the grammar.
1404 (rhses.1): Allow one or more semicolons after any rule, including
1405 just before "|" as required by POSIX.
1406 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
1407 grammar.
1408
1409 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
1410
1411 %parse-param support for lalr1.cc.
1412
1413 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
1414 b4_cc_constructor_calls, b4_cc_constructor_call,
1415 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
1416 definitions.
1417 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
1418 parse-param arguments.
1419 (yy::b4_parser_class_name): Declare instance variables to
1420 hold parse-param arguments.
1421 * tests/calc.at: s/value/semantic_value/ because value clashes
1422 with a member of yy::b4_parser_class_name. Adjust C++ code
1423 to handle %parse-param. Enable %parse-param test in C++.
1424
1425 2003-05-12 Paul Eggert <eggert@twinsun.com>
1426
1427 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
1428 English a bit. Fix fclose typo. Change "const char" to "char
1429 const", and use ANSI C rather than K&R for "main". Suggest
1430 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
1431 and suggest yy_switch_to_buffer.
1432
1433 2003-05-05 Paul Eggert <eggert@twinsun.com>
1434
1435 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
1436 C89. This avoids a diagnostic on compilers that define __STDC__
1437 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
1438 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
1439
1440 2003-05-03 Paul Eggert <eggert@twinsun.com>
1441
1442 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
1443 Do not overrun array bounds.
1444 This should fix a bug reported today by Olatunji Oluwabukunmi in
1445 <http://mail.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
1446
1447 2003-04-29 Akim Demaille <akim@epita.fr>
1448
1449 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
1450 * src/getargs.c, src/getargs.h: here, as bool, not int.
1451 (nondeterministic_parser): New.
1452 * src/parse-gram.y, src/scan-gram.l: Support
1453 %nondeterministic-parser.
1454 * src/output.c (prepare): Use nondeterministic_parser instead
1455 of glr_parser where appropriate.
1456 * src/tables.c (conflict_row, action_row, save_row)
1457 (token_actions, token_actions, pack_vector): Ditto.
1458
1459 2003-04-29 Akim Demaille <akim@epita.fr>
1460
1461 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
1462
1463 2003-04-29 Akim Demaille <akim@epita.fr>
1464
1465 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
1466 with %pure-parser and %locations to exercise the patch from Yakov
1467 Markovitch below.
1468
1469 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
1470
1471 * data/yacc.c: (b4_lex_param): Corrected for the case where
1472 %lex-param is provided and %pure-parser isn't.
1473
1474 2003-04-27 Paul Eggert <eggert@twinsun.com>
1475
1476 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
1477 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
1478 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
1479 if it is not defined.
1480 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
1481
1482 2003-04-26 Paul Eggert <eggert@twinsun.com>
1483
1484 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
1485 Declare to be of type suitable for the ninf value itself, not of
1486 type suitable for the corresponding table, since the latter might
1487 be unsigned but the ninf value might be negative. This fixes a
1488 bug reported by Alexandre Duret-Lutz in
1489 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
1490
1491 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
1492 invokes it. We shouldn't invoke it twice because it will attempt
1493 to put error.o in the archive twice. This fixes a glitch reported
1494 by Martin Mokrejs in
1495 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
1496
1497 2003-04-21 Paul Eggert <eggert@twinsun.com>
1498
1499 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
1500 to gnulib.
1501
1502 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
1503
1504 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
1505 Fix obvious typo that results in uncompilable GLR parsers
1506 when both %pure-parser and %locations are used. (trivial change)
1507
1508 2003-04-17 Paul Eggert <eggert@twinsun.com>
1509
1510 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
1511 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
1512 Do not insert the expected token via unput, as this runs afoul
1513 of a POSIX-compatibility bug in flex 2.5.31.
1514 All uses changed to BEGIN the parent state,
1515 since we no longer insert the expected token via unput.
1516 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
1517 that is no longer emitted after the above change.
1518
1519 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
1520 the first one. This change is from Paul Hilfinger, and it fixes
1521 regression reported by Werner Lemberg in
1522 <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
1523
1524 (resolve_sr_conflict): Don't invoke state_errs_set
1525 unless one or more tokens have been explicitly made errors.
1526 Otherwise, the above change causes Bison to abort.
1527
1528 * tests/existing.at (GNU pic Grammar): New test case, taken from
1529 Lemberg's email.
1530
1531 2003-03-31 Akim Demaille <akim@epita.fr>
1532
1533 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
1534
1535 2003-03-31 Akim Demaille <akim@epita.fr>
1536
1537 * src/output.c (prepare_symbols): Avoid trailing spaces in the
1538 output.
1539
1540 2003-03-31 Akim Demaille <akim@epita.fr>
1541
1542 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
1543 From Paul Hilfinger.
1544
1545 2003-03-29 Akim Demaille <akim@epita.fr>
1546
1547 * m4/error.m4: Do not put under dynamic conditions some code which
1548 expansion is under static control.
1549
1550 2003-03-29 Akim Demaille <akim@epita.fr>
1551
1552 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
1553
1554 2003-03-29 Akim Demaille <akim@epita.fr>
1555
1556 * doc/bison.texinfo (Strings are Destroyed): New.
1557
1558 2003-03-13 Paul Eggert <eggert@twinsun.com>
1559
1560 * .cvsignore: Add configure.lineno.
1561 * src/.cvsignore: Add yacc.
1562 * tests/.cvsignore: Add testsuite.log.
1563 * doc/fdl.texi: Sync with latest FSF version.
1564
1565 2003-03-12 Paul Eggert <eggert@twinsun.com>
1566
1567 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
1568 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
1569 cursor, instead of leaving it undefined. This fixes a bug
1570 reported by Tim Van Holder in
1571 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
1572 * tests/input.at (Torturing the Scanner): Test the scanner on
1573 an empty input file, which was Tim Van Holder's test case.
1574
1575 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
1576 <sys/resource.h> can be included, include sys/time.h and
1577 sys/times.h first, if available. This works around the SunOS
1578 4.1.4 porting bug reported by Bruce Becker in
1579 <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
1580
1581 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
1582 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
1583 AC_HEADER_SYS_WAIT.
1584
1585 Merge changes from gnulib. This was prompted because the CVS
1586 snapshot didn't build on Solaris 7 due to strnlen problems.
1587
1588 These changes need to be merged back into gnulib:
1589 * lib/hash.c: Include <stdbool.h> unconditionally.
1590 * m4/onceonly.m4 (m4_quote): New macro.
1591 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
1592 Quote AC_FOREACH variable-expansions properly.
1593 The 2003-01-03 obstack.h change also needs merging.
1594 {end of changes requiring merging}
1595
1596 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
1597 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
1598 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
1599 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
1600 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
1601 New files, imported from gnulib.
1602 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
1603 above.
1604
1605 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
1606 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
1607 gnulib sources.
1608
1609 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
1610 Add.
1611 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
1612 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
1613 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
1614 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
1615 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
1616 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
1617 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
1618 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
1619 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
1620 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
1621 (jm_PREREQ_ARGMATCH): Remove.
1622 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
1623 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
1624
1625 * src/system.h: Include <stdbool.h> unconditionally.
1626
1627 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
1628 assuming at least C89 in the bitset code for some time now.
1629
1630 2003-03-03 Akim Demaille <akim@epita.fr>
1631
1632 * ro.po: New.
1633
1634 2003-03-02 Akim Demaille <akim@epita.fr>
1635
1636 * doc/bison.texinfo (Table of Symbols): Reactivate the
1637 documentation for %lex-param, and %parse-param.
1638
1639 2003-03-02 Akim Demaille <akim@epita.fr>
1640
1641 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
1642 generate verbose error messages.
1643 Use the number of tokens as an upper bound in yytname, as it
1644 cannot be a non terminal.
1645
1646 2003-03-02 Akim Demaille <akim@epita.fr>
1647
1648 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
1649 message.
1650
1651 2003-03-02 Akim Demaille <akim@epita.fr>
1652
1653 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
1654 Use them to exercise yycheck overrun.
1655 Based on Andrew Suffield's grammar.
1656
1657 2003-03-02 Akim Demaille <akim@epita.fr>
1658
1659 Create tests/local.at for Bison generic testing macros.
1660
1661 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
1662 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
1663 This new file.
1664 * tests/calc.at (AT_CHECK_CALC): Adjust.
1665 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
1666 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
1667 * tests/local.at: here.
1668 (AT_COMPILE_CXX): Tags the tests using it as c++.
1669 Ignore the test if CXX is not functional.
1670
1671 2003-03-01 Paul Eggert <eggert@twinsun.com>
1672
1673 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
1674 not loc->end, since loc->end might contain garbage and this leads
1675 to undefined behavior on some platforms.
1676 (id_loc, token_start): Use (IF_LINTed) initial values that do not
1677 depend on *loc, so that the reader doesn't give the the false
1678 impression that *loc is initialized.
1679 (<INITIAL>"%%"): Do not bother setting code_start, since its value
1680 does not survive the return.
1681
1682 2003-03-01 Akim Demaille <akim@epita.fr>
1683
1684 * src/scan-gram.l (code_start): Always initialize it when entering
1685 into yylex, as SC_EPILOGUE is activated *before* the corresponding
1686 yylex invocation. An alternative would be making it static, but
1687 then it starts with the second %%'s beginning, instead of its end.
1688
1689 2003-02-28 Paul Eggert <eggert@twinsun.com>
1690
1691 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
1692 around a UnixWare 7.1.1 porting bug reported by John Hughes in
1693 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
1694
1695 2003-02-26 Paul Eggert <eggert@twinsun.com>
1696
1697 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
1698 Remove Sequent/Pyramid discussion (nobody uses them any more).
1699 Merge VMS and MS-DOS discussion; these ports may well be dead
1700 but let's keep mentioning them for now. Put <> around email
1701 addresses. Add copyright notice.
1702
1703 2003-02-24 Paul Eggert <eggert@twinsun.com>
1704
1705 * data/glr.c (yy_reduce_print): yylineno -> yylno,
1706 to avoid collision with flex use of yylineno.

1714 2003-02-21 Akim Demaille <akim@epita.fr>
1715
1716 * data/lalr1.cc: Use temporary variables instead of casts to
1717 change integer types.
1718 Suggested by Paul Eggert.
1719
1720 2003-02-21 Akim Demaille <akim@epita.fr>
1721
1722 * doc/bison.texinfo: Use "location" consistently to refer to @n,
1723 to avoid confusions with lalr1.cc's notion of Position.
1724 Suggested by Paul Eggert.
1725
1726 2003-02-20 Akim Demaille <akim@epita.fr>
1727
1728 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
1729 before initial_columns.
1730 (location.hh): Use consistent variable names when defining the
1731 operator<<.
1732 Use "last" so that we subtract from Positions, not from unsigned.
1733
1734 2003-02-20 Akim Demaille <akim@epita.fr>
1735
1736 * data/lalr1.cc (position.hh): New subfile, including the extended
1737 and Doxygen'ed documentation of class Position.
1738 (location.hh): Use it.
1739 Document a` la Doxygen.

1743
1744 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
1745 AT_YACC_IF.
1746 Redefine AT_YYERROR_SEES_LOC_IF using it.
1747 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
1748 not defined.
1749 Don't use the location in yy::Parser::error_ and
1750 yy::Parser::print_ when not %locations.
1751 Activate more lalr1.cc tests.
1752
1753 2003-02-19 Akim Demaille <akim@epita.fr>
1754
1755 * data/lalr1.cc: When displaying a line number, be sure to make it
1756 an int.
1757
1758 2003-02-19 Akim Demaille <akim@epita.fr>
1759
1760 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
1761 Remove, useless.
1762 (YYABORT, YYACCEPT, YYERROR): New.
1763 * tests/calc.at: Renable the lalr1.cc test.
1764
1765 2003-02-19 Akim Demaille <akim@epita.fr>

1768 error recovery, mixing with/without pops and discarding of the
1769 lookahead.
1770 Exercise YYERROR.
1771 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
1772
1773 2003-02-17 Paul Eggert <eggert@twinsun.com>
1774
1775 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
1776 * tests/testsuite.at (AT_COMPILE): Use them.
1777 This fixes the testsuite problem reported by Robert Lentz in
1778 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
1779
1780 2003-02-12 Paul Eggert <eggert@twinsun.com>
1781
1782 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
1783 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
1784 <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
1785 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
1786 Check for malloc failure, for consistency with yacc.c.
1787 (yytname_size): Remove, for consistency with yacc.c.
1788
1789 The bug still remains in data/lalr1.cc, as I didn't have time
1790 to fix it there.
1791
1792 2003-02-06 Akim Demaille <akim@epita.fr>
1793
1794 * configure.ac (GXX): Rename as...
1795 (CXX): this, to keep the original Autoconf semantics.
1796 Require 2.57.
1797 * data/lalr1.cc: Fix b4_copyright invocations.

1801 (Position::Position ()): New.
1802 (operator<< (Position)): New.
1803 (operator- (Position, int)): New.
1804 (Location::first, Location::last): Rename as...
1805 (Location::begin, Location::end): these, to mock the conventional
1806 iterator names.
1807 (operator<< (Location)): New.
1808 * tests/atlocal.in (CXX): New.
1809 * tests/testsuite.at (AT_COMPILE_CXX): New.
1810 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
1811 locations in a more synthetic way.
1812 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
1813 lalr1.cc is used.
1814 Adjust the C locations to match those from Emacs: first column is
1815 column 0.
1816 Change all the expected results.
1817 Conform to the GCS: simplify the locations when applicable.
1818 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
1819 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
1820 these CPP macros with the m4 macros new defined by...
1821 (AT_CHECK_PUSHDEFS): this, i.e.:
1822 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)

1824 New macros.
1825 (AT_CHECK_POPDEFS): Undefine them.
1826 (AT_CHECK_CALC_LALR1_CC): New.
1827 Use it for the first lalr1.cc test.
1828
1829 2003-02-04 Akim Demaille <akim@epita.fr>
1830
1831 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
1832 Location as is defined.
1833
1834 2003-02-04 Akim Demaille <akim@epita.fr>
1835
1836 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
1837 name_ being defined.
1838
1839 2003-02-03 Paul Eggert <eggert@twinsun.com>
1840
1841 * src/gram.h (start_symbol): Remove unused decl.
1842
1843 Use more-consistent naming conventions for local vars.
1844
1845 * src/derives.c (derives_compute): Change type of local var from
1846 int to rule_number.
1847 * src/gram.c (grammar_rules_partial_print): Likewise.
1848 * src/print.c (print_core): Likewise.
1849 * src/reduce.c (reduce_grammar_tables): Likewise.
1850
1851 * src/gram.c (grammar_dump): Change name of item_number *
1852 local var from r to rp.

1854
1855 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
1856
1857 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
1858 for symbol or symbol_number var.
1859 * src/reader.c (grammar_start_symbol_set): Likewise.
1860 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
1861 Likewise.
1862 * src/state.c (transitions_to): Likewise.
1863 * src/state.h: Likewise.
1864 * src/tables.c (symbol_number_to_vector_number): Likewise.
1865
1866 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
1867 char * var.
1868
1869 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
1870 var.
1871
1872 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
1873 var.
1874
1875 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
1876 Use str, not s, for char * var. Use ch, not c, for character var.
1877 Use size for size var.
1878

1880 char * var.
1881 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for

1886 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
1887 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
1888 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
1889 param to have same name as that of enum, so that we don't use
1890 "s" to stand for a non-state.
1891
1892 2003-02-02 Akim Demaille <akim@epita.fr>
1893
1894 * src/scan-skel.l: Scan more than one inert character per yylex
1895 invocation.
1896
1897 2003-02-01 Paul Eggert <eggert@twinsun.com>
1898
1899 Version 1.875a.
1900
1901 * po/LINGUAS: Add ms.
1902
1903 2003-01-30 Akim Demaille <akim@epita.fr>
1904
1905 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
1906
1907 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1908
1909 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
1910 of $1.
1911
1912 Changes in response to error report by S. Eken: GLR mode does not
1913 handle negative $ indices or $ indices in embedded rules correctly.
1914 See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
1915
1916 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
1917 (b4_rhs_location): Ditto.
1918 (yyfill): New function to copy from stack tree into array
1919 incrementally.
1920 (yyuserAction): Modify to allow incremental move of semantic values
1921 to rhs array when in GLR mode.
1922 Define YYFILL to use in user-defined actions to fill semantic array
1923 as needed.
1924 Remove dummy use of yystack, as there is now a guaranteed use.
1925 (yydoAction): Modify to allow incremental move of semantic values
1926 to rhs array when in GLR mode.
1927 (yyresolveAction): Ditto.
1928 (yyglrShiftDefer): Update comment.
1929 (yyresolveStates): Use X == NULL for pointers, not !X.
1930 (yyglrReduce): Ditto.
1931 (yydoAction): Ditto
1932
1933 * tests/glr-regr1.at: Rename to ...
1934 * tests/glr-regression.at: Add new regression test for the problems
1935 described above (adapted from S. Eken).
1936 Update copyright notice.
1937 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
1938 * tests/Makefile.am: Ditto.
1939
1940 2003-01-28 Paul Eggert <eggert@twinsun.com>
1941
1942 * data/lalr1.cc: Do not use @output_header_name@ unless
1943 b4_defines_flag is set. This fixes two bugs reported by
1944 Tim Van Holder in
1945 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
1946 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
1947
1948 2003-01-21 Paul Eggert <eggert@twinsun.com>
1949
1950 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
1951 we don't need to worry about yyerrlab1 being reported as an
1952 "unused label" by non-GCC C compilers. The downside is that if
1953 locations are used then a couple of statements are duplicated each
1954 time YYERROR is invoked, but the upside is that the warnings
1955 should vanish.
1956 (yyerrlab1): Move code to YERROR.
1957 (yyerrlab2): Remove. Change uses back to yyerrlab1.
1958 This reverts some of the 2002-12-27 change.
1959
1960 2003-01-17 Paul Eggert <eggert@twinsun.com>
1961
1962 * src/output.c (symbol_printers_output): Fix typo that led
1963 to core dump. Problem reported by Antonio Rus in
1964 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
1965
1966 2003-01-13 Akim Demaille <akim@epita.fr>,
1967 Quoc Peyrot <chojin@lrde.epita.fr>,
1968 Robert Anisko <anisko_r@lrde.epita.fr>
1969
1970 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
1971 when the stacks contain one element, as the loop would otherwise
1972 free the last state, and then use the top state (the one we just
1973 popped). This means that the initial elements will not be freed
1974 explicitly, as is the case in yacc.c; it is not a problem, as
1975 these elements have fake values.
1976
1977 2003-01-11 Paul Eggert <eggert@twinsun.com>
1978
1979 * NEWS: %expect-violations are now just warnings, reverting
1980 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
1981 bootstrapping problem reported by Matthias Klose; see
1982 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
1983 * src/conflicts.c (conflicts_print): Likewise.
1984 * tests/conflicts.at (%expect not enough, %expect too much,
1985 %expect with reduce conflicts): Likewise.
1986 * doc/bison.texinfo (Expect Decl): Document this. Also mention
1987 that the warning is enabled if the number of conflicts changes
1988 (not necessarily increases).
1989
1990 * src/getargs.c (version): Update copyright year.
1991
1992 2003-01-09 Akim Demaille <akim@epita.fr>
1993
1994 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
1995
1996 2003-01-08 Paul Eggert <eggert@twinsun.com>
1997
1998 * Makefile.maint (WGETFLAGS):
1999 New macro, containing "-C off" to disable proxy caches.
2000 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
2001 (rel-check): Use $(WGET) instead of wget.
2002
2003 2003-01-06 Paul Eggert <eggert@twinsun.com>
2004
2005 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
2006 the GLR paper of Scott, Johnstone and Hussain.
2007
2008 2003-01-04 Paul Eggert <eggert@twinsun.com>
2009
2010 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
2011 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
2012 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
2013 (EXTRA_LIBRARIES): New var, for liby.a.
2014 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
2015 (EXTRA_SCRIPTS): New var, for yacc.
2016
2017 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
2018 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
2019 Problem reported by Nelson H. F. Beebe.
2020
2021 2003-01-03 Paul Eggert <eggert@twinsun.com>
2022
2023 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
2024 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
2025 when compiling Bison 1.875's `bitset bset = obstack_alloc
2026 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
2027
2028 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
2029 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
2030 grow to a huge size with typical invocation.
2031
2032 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
2033 Use the pattern recommended by Autoconf 2.57, except also protect
2034 against double-definition.
2035 * src/system.h: Likewise.
2036 Portability issues reported by Nelson H. F. Beebe.
2037
2038 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
2039 All uses changed. Provide a definition in both C and C++.
2040 (yytrue, yyfalse): Define even if defined (__cplusplus).
2041
2042 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
2043 Reported by Nelson H. F. Beebe.
2044
2045 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
2046
2047 2003-01-02 Paul Eggert <eggert@twinsun.com>
2048
2049 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
2050 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
2051 Bug reported by Nelson H. F. Beebe.
2052
2053 2003-01-01 Paul Eggert <eggert@twinsun.com>
2054
2055 * Version 1.875.
2056
2057 2002-12-30 Paul Eggert <eggert@twinsun.com>
2058
2059 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
2060 Moved here from...
2061 (<INITIAL>","): Here. This causes stray "," to be treated
2062 more uniformly.
2063
2064 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
2065 last brace in braced code when not in Yacc mode, for compatibility
2066 with Bison 1.35. This resurrects the 2001-12-15 patch to
2067 src/reader.c.
2068
2069 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
2070 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
2071
2072 2002-12-28 Paul Eggert <eggert@twinsun.com>
2073
2074 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
2075 that of SYM's type. This fixes Debian bug 168069, reported by
2076 Thomas Olsson.
2077
2078 2002-12-28 Paul Eggert <eggert@twinsun.com>
2079
2080 Version 1.75f.
2081
2082 Switch back to the Yacc style of conflict reports, undoing some
2083 of the 2002-07-30 change.
2084 * doc/bison.texinfo (Understanding): Use Yacc style for
2085 conflict reports. Also, use new way of locating rules.
2086 * src/conflicts.c (conflict_report):
2087 Renamed from conflict_report_yacc, removing the old
2088 'conflict_report'. Translate the entire conflict report at once,
2089 so that we don't assume that "," has the same interpretation in
2090 all languages.
2091 (conflicts_output): Use Yacc-style conflict report for each state,
2092 instead of our more-complicated style.
2093 (conflicts_print): Use Yacc-style conflict report, except print
2094 the input file name when not emulating Yacc.
2095 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
2096 Conflicted Reduction, %expect not enough, %expect too much,
2097 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
2098 * tests/existing.at (GNU Cim Grammar): Likewise.
2099 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
2100
2101 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
2102 fatal): Don't invoke fflush; it's not needed and it might even be
2103 harmful for stdout, as stdout might not be open.
2104 * src/reduce.c (reduce_print): Likewise.
2105

2107
2108 Fix a bug where error locations were not being recorded correctly.
2109 This problem was originally reported by Paul Hilfinger in
2110 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
2111
2112 * data/yacc.c (yyparse): New local var yylerrsp, to record the
2113 top of the location stack's error locations.
2114 (yyerrlab): Set it. When discarding a token, push its location
2115 onto yylerrsp so that we don't lose track of the error's end.
2116 (yyerrlab1): Now is only the target of YYERROR, so that we can
2117 properly record the location of the action that failed. For GCC
2118 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
2119 GCC warning about yyerrlab1 being unused if YYERROR is unused.
2120 (yyerrlab2): New label, which yyerrlab now falls through to.
2121 Compute the error's location by applying YYLLOC_DEFAULT to
2122 the locations of all the symbols that went into the error.
2123 * doc/bison.texinfo (Location Default Action): Mention that
2124 YYLLOC_DEFAULT is also invoked for syntax errors.
2125 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
2126 Error locations include the locations of all the tokens that were
2127 discarded, not just the last token.
2128
2129 2002-12-26 Paul Eggert <eggert@twinsun.com>
2130
2131 * src/files.c: Include quote.h.
2132 (compute_output_file_names): Warn if we detect conflicting
2133 outputs to the same file. This should catch the misunderstanding
2134 exemplified by Debian Bug 165349, reported by Bruce Stephens..
2135
2136 * src/conflicts.c (conflicts_print): If the user specifies
2137 "%expect N", report an error if there are any reduce/reduce
2138 conflicts. This is what the manual says should happen.
2139 This fixes Debian bug 130890, reported by Anthony DeRobertis.
2140 * tests/conflicts.at (%expect with reduce conflicts): New test.
2141
2142 Don't use m4_include on relative file names, as it doesn't work as
2143 desired if there happens to be a file with that name under ".".
2144
2145 * m4sugar/version.m4: Remove; it was included but it wasn't used.
2146 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
2147 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
2148 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
2149 * src/output.c (output_skeleton): Use full path names when
2150 specifying a file to include; don't rely on include path, as
2151 it's unreliable when the working file contains a file with
2152 that name.
2153
2154 2002-12-25 Paul Eggert <eggert@twinsun.com>
2155
2156 Remove obsolete references to bison.simple and bison.hairy.
2157 Problem mentioned by Aubin Mahe in
2158 <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
2159 * data/glr.c: Comment fix.
2160 * doc/bison.1: Remove references. Also, mention "yacc".
2161
2162 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
2163 with -g option.
2164
2165 * src/parse-gram.y (declaration): Use enum "report_states" rather
2166 than its numeric value 1.
2167
2168 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
2169 opening a new one. This fixes Debian bug 165349, reported by
2170 Bruce Stephens.
2171
2172 2002-12-24 Paul Eggert <eggert@twinsun.com>
2173
2174 Version 1.75e.
2175
2176 * Makefile.maint (cvs-update): Don't assume that the shell
2177 supports $(...), as Solaris sh doesn't.
2178
2179 * src/parse-gram.y (lloc_default): Remove test for empty
2180 nonterminals at the end, since it didn't change the result.
2181
2182 2002-12-24 Paul Eggert <eggert@twinsun.com>
2183
2184 If the user does not define YYSTYPE as a macro, Bison now declares it
2185 using typedef instead of defining it as a macro. POSIX requires this.
2186 For consistency, YYLTYPE is also declared instead of defined.
2187
2188 %union directives can now have a tag before the `{', e.g., the
2189 directive `%union foo {...}' now generates the C code
2190 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
2191 The default union tag is `YYSTYPE', for compatibility with Solaris 9
2192 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
2193 instead of `yyltype'.
2194
2195 `yystype' and `yyltype' are now obsolescent macros instead of being
2196 typedefs or tags; they are no longer documented and will be
2197 withdrawn in a future release.
2198
2199 * data/glr.c (b4_location_type): Remove.
2200 (YYSTYPE): Renamed from yystype.
2201 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
2202 (struct YYLTYPE): Renamed from struct yyltype.
2203 (YYLTYPE): Renamed from yyltype.
2204 (yyltype, yystype): New (and obsolescent) macros,
2205 for backward compatibility.
2206 * data/yacc.c: Likewise.
2207
2208 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
2209 does not specify a union tag. This is for compatibility with
2210 Solaris 9 yacc.
2211
2212 * src/parse-gram.y (add_param): 2nd arg is now char * not char
2213 const *, since it is now modified by stripping surrounding { }.
2214 (current_braced_code): Remove.
2215 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
2216 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
2217 trailing " {...}". Now of type <chars>.
2218 (grammar_declaration): Adjust to bundled tokens.
2219 (code_content): Remove; stripping is now done by add_param.
2220 (print_token_value): Print contents of bundled tokens.
2221 (token_name): New function.
2222
2223 * src/reader.h (braced_code, current_braced_code): Remove.
2224 (token_name): New decl.
2225
2226 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
2227 token_type, not braced_code code_kind. All uses changed.
2228 (SC_PRE_CODE): New state, for scanning after a keyword that
2229 has (or usually has) an immediately-following braced code.
2230 (token_type): New local var, to keep track of which token type
2231 to return when scanning braced code.
2232 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
2233 <INITIAL>"%parse-param", <INITIAL>"%printer",
2234 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
2235 instead of returning a token type immediately.
2236 (<INITIAL>"{"): Set token type.
2237 (<SC_BRACED_CODE>"}"): Use it.
2238 (handle_action_dollar, handle_action_at): Now returns bool
2239 indicating success. Fail if ! current_rule; this prevents a core dump.
2240 (handle_symbol_code_dollar, handle_symbol_code_at):
2241 Remove; merge body into caller.
2242 (handle_dollar, handle_at): Complain in invalid contexts.
2243
2244 * NEWS, doc/bison.texinfo: Document the above.
2245 * NEWS: Fix years and program names in copyright notice.
2246
2247 2002-12-17 Paul Eggert <eggert@twinsun.com>
2248
2249 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
2250 Reporting, Table of Symbols): Omit mentions of %lex-param and
2251 %parse-param from the documentation for now.
2252
2253 2002-12-15 Paul Eggert <eggert@twinsun.com>
2254
2255 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
2256 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
2257 lookahead symbol, and which sets yychar in parser actions) and it
2258 disagreed with the Bison documentation. Bug
2259 reported by Andrew Walrond.
2260
2261 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
2262 as the caller now does that.
2263 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
2264 (YYEMPTY): Parenthesize right hand side, since others use it.
2265 (yyparse): Don't assume that our generated code is the only code
2266 that sets yychar.
2267
2268 2002-12-13 Paul Eggert <eggert@twinsun.com>
2269
2270 Version 1.75d.
2271
2272 POSIX requires a "yacc" command.
2273 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
2274 (MOSTLYCLEANFILES): Add yacc.
2275 (yacc): New rule.
2276 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
2277 as an alias for bison y.
2278
2279 * po/LINGUAS: Add da.
2280
2281 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
2282 problem with latest <getopt.h>.
2283 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
2284
2285 * doc/fdl.texi: Upgrade to 1.2.
2286 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
2287 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
2288 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
2289 gnulib.
2290 * config/install-sh: Sync with autotools.
2291
2292 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
2293 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
2294 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
2295 locations are requested.
2296 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
2297 locations are requested.
2298
2299 2002-12-12 Paul Eggert <eggert@twinsun.com>
2300
2301 Remove unportable casts and storage allocation tricks.
2302 While we're at it, remove almost all casts, since they
2303 usually aren't needed and are a sign of trouble.
2304
2305 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
2306
2307 * src/derives.c (derives_compute): Do not subtract NTOKENS from
2308 the pointer DSET returned by malloc; this isn't portable.
2309 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
2310 Similarly for DERIVES.
2311 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
2312 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
2313 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
2314
2315 * src/derives.c (derives_compute): Do not bother invoking
2316 int_of_rule_number, since rule numbers are integers.
2317
2318 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
2319 rather than XMALLOC (char, N).
2320
2321 * src/files.c (filename_split): Rewrite to avoid cast.
2322
2323 * src/gram.h (symbol_number_as_item_number,
2324 item_number_as_symbol_number, rule_number_as_item_number,
2325 item_number_as_rule_number):
2326 Now inline functions rather than macros, to avoid casts.
2327 * src/state.h (state_number_as_int): Likewise.
2328 * src/tables.c (state_number_to_vector_number,
2329 symbol_number_to_vector_number): Likewise.
2330
2331 * src/gram.h (int_of_rule_number): Remove; no longer used.
2332
2333 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
2334 since the resulting storage is always stored into.
2335
2336 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
2337 where it's needed.
2338
2339 * src/muscle_tab.c (muscle_m4_output):
2340 Now inline. Return bool, not int.
2341 * src/state.c (state_compare): Likewise.
2342 * src/symtab.c (symbol_check_defined,
2343 symbol_check_alias_consistency, symbol_pack, symbol_translation,
2344 hash_compare_symbol, hash_symbol):
2345 Likewise.
2346 * src/uniqstr.c (uniqstr_print): Likewise.
2347 * src/muscle_tab.c (muscle_m4_output_processor):
2348 New function, to avoid casts.
2349 * src/state.c (state_comparator, stage_hasher): Likewise.
2350 * src/symtab.c (symbol_check_defined_processor,
2351 symbol_check_alias_consistency_processor, symbol_pack_processor,
2352 symbol_translation_processor, hash_symbol_comparator,
2353 hash_symbol_hasher): Likewise.
2354 * src/uniqstr.c (uniqstr_print_processor): Likewise.
2355 * src/muscle_tab.c (muscles_m4_output):
2356 Use new functions instead of casting old functions unportably.
2357 * src/state.c (state_hash_new): Likewise.
2358 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
2359 symbols_token_translations_init):
2360 Likewise.
2361 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
2362
2363 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
2364 var instead of casting to long, to avoid casts.
2365 (prepare_states): Use MALLOC rather than alloca, so that we don't
2366 have to worry about alloca.
2367 * src/state.c (state_hash_lookup): Likewise.
2368
2369 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
2370 local var instead of casting to unsigned char, to avoid casts.
2371
2372 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
2373 STATE_ALLOC): Remove.
2374 (transitions_new, errs_new, reductions_new, state_new): Use malloc
2375 rather than calloc, and use offsetof to avoid allocating slightly
2376 too much storage.
2377 (state_new): Initialize all members.
2378
2379 * src/state.c (state_hash): Use unsigned accumulator, not signed.
2380
2381 * src/symtab.c (symbol_free): Remove; unused.
2382 (symbol_get): Remove cast in lhs of assignment.
2383 (symbols_do): Now static. Accept generic arguments, not
2384 hashing-related ones.
2385
2386 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
2387 (symbol_processor): Remove.
2388 (symbols_do): Remove decl; now static.
2389
2390 * src/system.h (alloca): Remove; decl no longer needed.
2391 (<stddef.h>): Include, for offsetof.
2392 (<inttypes.>, <stdint.h>): Include if available.
2393 (uintptr_t): New type, if system lacks it.
2394 (CALLOC, MALLOC, REALLOC): New macros.
2395 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
2396 new macros.
2397
2398 * src/tables.c (table_size): Now int, to pacify GCC.
2399 (table_grow, table_ninf_remap): Use signed table size.
2400 (save_row): Don't bother initializing locals when not needed.
2401 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
2402 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
2403
2404 * src/vcg.h: Correct misspellings.
2405
2406 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
2407
2408
2409 * src/getargs.c (getargs): Don't assume EOF == -1.
2410
2411 2002-12-09 Paul Eggert <eggert@twinsun.com>
2412
2413 Change identifier spellings to avoid collisions with names
2414 that are reserved by POSIX.
2415
2416 Don't use names ending in _t, since POSIX reserves them.
2417 For consistency, remove _e and _s endings -- they're weren't
2418 needed to remove ambiguity. All uses changed.
2419 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
2420 turn was just renamed from struniq_t.
2421 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
2422 which in turn was just renamed from struniq_processor_t.
2423 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
2424 in turn was renamed from hash_compare_struniq_t.
2425 * src/LR0.c (struct state_list): Renamed from struct state_list_s.

2447 (rule_list): Renamed from rule_list_t.
2448 * src/print_graph.c (static_graph): Renamed from graph.

2458 misspelled) transtion_s tag removed.
2459 (errs): Renamed from errs_t. Unused errs_s tag removed.

2463 (struct symbol_list): Renamed from struct symbol_list_s.

2491 * tests/calc.at (_AT_DATA_CALC_Y, Simple LALR Calculator):
2492 Rename value_t -> value.
2493 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
2494 value_t_as_yystype -> value_as_yystype.
2495
2496 Don't include <errno.h> in the mainstream code, since it
2497 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
2498 * lib/get-errno.c, lib/get-errno.h: New files.
2499 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
2500 get-errno.c.

2502 * src/output.c (output_skeleton): Likewise.
2503 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
2504 instead of errno.
2505 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>\\x[0-9abcdefABCDEF]+):
2506 Likewise.
2507 (handle_action_dollar, handle_action_at): Likewise.
2508 * src/system.h: Do not include <errno.h>.
2509 (TAB_EXT): Renamed from EXT_TAB.
2510 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
2511
2512 Avoid str[a-z]*, since <string.h> reserves that name space.
2513 Change all instances of "struniq" in names to "uniqstr", and
2514 likewise for "STRUNIQ" and "UNIQSTR".
2515 * src/uniqstr.c: Renamed from src/struniq.c.
2516 * src/uniqstr.h: Renamed from src/struniq.h.
2517 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.
2518 * src/files.c (strsuffix): Remove; unused.
2519 (concat2): Renamed from stringappend. Now static.
2520 * src/files.h (strsuffix, stringappend): Remove; unused.
2521 * src/parse-gram.y (<chars>): Renamed from <string>.
2522 (<uniqstr>): Renamed from <struniq>.
2523 * src/scan-gram.l (obstack_for_string): Renamed from string_obstack.
2524 * src/vcg.h (struct node_s.expand): Renamed from struct node_s.stretch.
2525 (struct graph_s.expand): Renamed from struct graph_s.stretch.
2526 * src/vcg_defaults.h (G_EXPAND): Renamed from G_STRETCH.
2527 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
2528 (N_EXPAND): Renamed from N_STRETCH.
2529
2530 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
2531 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
2532 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
2533 Remove; unused.
2534 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
2535 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
2536 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.
2537 * src/tables.c (VECTOR_NUMBER_MAX, VECTOR_NUMBER_MIN): Remove; unused.
2538 (BASE_MAXIMUM): Renamed from BASE_MAX.
2539 (BASE_MINIMUM): Renamed from BASE_MIN.
2540 (ACTION_MAX): Remove; unused.
2541 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
2542 Unnecessary casts removed from above defines.
2543
2544
2545 Fix misspelling in names.
2546 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
2547 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
2548 G_NODE_ALIGNEMENT.
2549
2550
2551 * lib/timevar.c (timevar_report): Renamed from time_report,
2552 for consistency with other names.
2553 * lib/timevar.h (timevar_report): New decl.
2554 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
2555
2556
2557 Sort include-file uses.
2558
2559 Reorder all include files under src to be in the order "system.h".
2560 then the ../lib include files in angle brackets (alphabetized),
2561 then the . include files in double-quotes (alphabetized). Fix
2562 dependency breakages encountered in this process, as follows:
2563 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
2564 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
2565 * src/state.h: Include "symtab.h".
2566
2567 2002-12-08 Paul Eggert <eggert@twinsun.com>
2568
2569 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
2570 since this causes problems when __file__ contains character
2571 sequences like "@" that are treated specially by src/scan-skel.l.
2572 Instead, just use the file's basename. This fixes the bug
2573 reported by Martin Mokrejs in
2574 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
2575
2576 2002-12-06 Paul Eggert <eggert@twinsun.com>
2577
2578 Add support for rules that do not have trailing semicolons, as
2579 POSIX requires. Improve the quality of locations in Bison
2580 diagnostics.
2581
2582 * src/location.c: Include <quotearg.h>.
2583 (empty_location): Now const.
2584 (location_print): New function. Follow the recommendation of the
2585 GNU Coding Standards for locations that span file boundaries.
2586 * src/location.h: Do not include <quotearg.h>; no longer needed.
2587 (boundary): New type.
2588 (location_t): Use it. This allows locations to span file boundaries.
2589 All member uses changed: file -> start.file or end.file (as needed),
2590 first_line -> start.line, first_column -> start.column,
2591 last_line -> end.line, last_column -> end.column.
2592 (equal_boundaries): New function.
2593 (LOCATION_RESET, LOCATION_STEP): Remove.
2594 (LOCATION_PRINT): Remove. All callers changed to use location_print.
2595 (empty_location): Now const.
2596 (location_print): New decl.
2597 * src/parse-gram.y (lloc_default): New function, which handles
2598 empty locations more accurately.
2599 (YYLLOC_DEFAULT): Use it.
2600 (%token COLON): Remove.
2601 (%token ID_COLON): New token.
2602 (rules): Use it.
2603 (declarations, rules): Remove trailing semicolon.
2604 (declaration, rules_or_grammar_declaration):
2605 Allow empty (";") declaration.
2606 (symbol_def): Remove empty actions; no longer needed.
2607 (rules_or_grammar_declaration): Remove trailing semicolon.
2608 (semi_colon.opt): Remove.
2609 * src/reader.h: Include location.h.
2610 (scanner_cursor): New decl.
2611 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
2612 rolling our own.
2613 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
2614 of *loc.
2615 (STEP): Remove. No longer needed, now that adjust_location does
2616 the work. All uses removed.
2617 (scanner_cursor): New var.
2618 (adjust_location): Renamed from extend_location. It now sets
2619 *loc and adjusts the scanner cursor. All uses changed.
2620 Don't bother testing for CR.
2621 (handle_syncline): Remove location arg; now updates scanner cursor.
2622 All callers changed.
2623 (unexpected_end_of_file): Now accepts start boundary of token or
2624 comment, not location. All callers changed. Update scanner cursor,
2625 not the location.
2626 (SC_AFTER_IDENTIFIER): New state.
2627 (context_state): Renamed from c_context. All uses changed.
2628 (id_loc, code_start, token_start): New local vars.
2629 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
2630 processing of Yacc white space and equivalents here.
2631 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
2632 instead of returning ID immediately, since we need to search for
2633 a subsequent colon.
2634 (<INITIAL>"'", "\""): Save token_start.
2635 (<INITIAL>"%{", "{", "%%"): Save code_start.
2636 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
2637 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
2638 BEGIN context_state at end, not INITIAL.
2639 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
2640 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
2641 Return correct token start.
2642 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
2643 the start of a character, string or multiline comment is found.
2644 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
2645 Reduction): Adjust reported locations to match the more-precise
2646 results now expected.
2647 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
2648 * tests/reduce.at (Useless Rules, Reduced Automaton,
2649 Underivable Rules): Likewise.
2650 * tests/regression.at (Invalid inputs): No longer `expecting ";"
2651 or "|"' now that so many other tokens are allowed by the new grammar.
2652
2653 * src/complain.h (current_file): Remove duplicate decl;
2654 current_file is now owned by files.h.
2655 * src/complain.c, src/scan-gram.l: Include files.h.
2656
2657 2002-12-06 Paul Eggert <eggert@twinsun.com>
2658
2659 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
2660 promotes to int; it might be unsigned int.
2661 * data/yacc.c (yy_reduce_print): Likewise.
2662
2663 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
2664 be #defined in the prologue, not in the Bison declarations.
2665 This fixes Debian Bug 102878, reported by Shaul Karl.
2666
2667 2002-12-02 Paul Eggert <eggert@twinsun.com>
2668
2669 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
2670 * lib/strtoul.c: New file, from gnulib.
2671 This fixes a porting bug reported by Peter Klein in
2672 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
2673
2674 2002-11-30 Paul Eggert <eggert@twinsun.com>
2675
2676 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
2677 and put only a forward declaration in the prologue. This is for
2678 consistency with the other scanner helper functions.
2679
2680 Type clashes now generate warnings, not errors, since it
2681 appears that POSIX may allow some grammars with type clashes.
2682 * src/reader.c (grammar_current_rule_check): Warn about
2683 type clashes instead of complaining.
2684 * tests/input.at (Type Clashes): Expect warnings, not complaints.
2685
2686 Add Yacc library, since POSIX requires it.
2687 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
2688 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
2689 * lib/main.c, lib/yyerror.c: New files.
2690
2691 gram_error can be static; it need not be extern.
2692 * src/reader.h (gram_error): Remove decl.
2693 * src/parse-gram.y (gram_error): Now static. Add static decl.
2694 (print_token_value): Omit parameter names from forward decl,
2695 for consistency.
2696
2697 2002-11-29 Paul Eggert <eggert@twinsun.com>
2698
2699 * doc/bison.texinfo: Emphasize that yylex and yyerror must
2700 be declared before being used. E.g., one should typically
2701 declare them in the prologue. Use GNU coding style in examples.
2702 Put "const" consistently after the type it modifies. Mention
2703 that C99 supports "inline". Mention that yyerror traditionally
2704 returns "int".
2705
2706 %parse-param and %lex-param now take just one argument, the
2707 declaration; the argument name is deduced from the declaration.
2708
2709 * doc/bison.texinfo (Parser Function, Pure Calling, Error
2710 Reporting, Table of Symbols): Document this.
2711 * src/parse-gram.y (add_param): New function.
2712 (COMMA): Remove.
2713 (declaration): Implement new rule for %parse-param and %lex-param.
2714 * src/scan-gram.l: "," now elicits a warning, rather than being
2715 a token; this is more compatible with byacc.
2716 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
2717
2718 2002-11-27 Paul Eggert <eggert@twinsun.com>
2719
2720 Rename identifiers to avoid real and potential collisions.
2721
2722 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
2723 to avoid collision with lex macro described by Bruce Lilly in
2724 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
2725 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
2726 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
2727 * src/parse-gram.y (print_token_value): Renamed from yyprint.
2728 All uses changed.
2729 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
2730 The name "yycontrol" violates the name space rules, and this stuff
2731 wasn't being used anyway.
2732 (input): Remove action; this stuff wasn't being used.
2733 (gram_error): Rename local variable yylloc -> loc.
2734 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
2735 (YY_DECL): Don't use "yy" at start of local variables.
2736 All uses changed, e.g., yylloc -> loc.
2737 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
2738 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
2739 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
2740 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
2741
2742 * src/parse-gram.y (gram_error): loc is now const *.
2743 * src/reader.h (gram_error): Likewise.
2744
2745 2002-11-24 Paul Eggert <eggert@twinsun.com>
2746
2747 Version 1.75c.
2748
2749 * tests/actions.at (Actions after errors): Use an output format
2750 more similar to that of the Printers and Destructors test.
2751 Test the position of the ';' token too.
2752 (Printers and Destructors): Likewise.
2753 (Printers and Destructors: %glr-parser): Remove for now, to avoid
2754 unnecessarily alarming people when the test fails.
2755
2756 * data/yacc.c (yyerrlab1): Move this label down, so that the
2757 parser does not discard the lookahead token if the user code
2758 invokes YYERROR. This change is required for POSIX conformance.
2759
2760 * lib/error.c: Sync with gnulib.
2761
2762 2002-11-22 Paul Eggert <eggert@twinsun.com>
2763
2764 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
2765 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
2766 * lib/xmalloc.c: Likewise.
2767
2768 2002-11-20 Paul Eggert <eggert@twinsun.com>
2769
2770 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
2771
2772 2002-11-20 Paul Eggert <eggert@twinsun.com>
2773
2774 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
2775 should use `if (! x) abort ();' rather than `assert (x);', and
2776 anyway it's one less thing to worry about configuring.
2777
2778 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
2779 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
2780 and replace all instances of assert with abort.
2781 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
2782 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
2783
2784 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
2785 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
2786 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
2787 hash_find_entry, hash_rehash, hash_insert): Likewise.
2788 * src/conflicts.c (resolve_sr_conflict): Likewise.
2789 * src/lalr.c (set_goto_map, map_goto): Likewise.
2790 * src/nullable.c (nullable_compute): Likewise.
2791 * src/output.c (prepare_rules, token_definitions_output): Likewise.
2792 * src/reader.c (packgram, reader): Likewise.
2793 * src/state.c (state_new, state_free, state_transitions_set,
2794 state_reduction_find): Likewise.
2795 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
2796 symbol_pack): Likewise.
2797 * src/tables.c (conflict_row, pack_vector): Likewise.
2798 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
2799 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
2800 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
2801 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
2802
2803 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
2804 (ARGMATCH_CONSTRAINT): New macro.
2805 (ARGMATCH_ASSERT): Use it.
2806
2807 * src/system.h (verify): New macro.
2808 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
2809 rather than assert.
2810 * src/tables.c (tables_generate): Likewise.
2811
2812 * src/struniq.c (struniq_assert): Now returns void, and aborts
2813 if the assertion is false.
2814 (struniq_assert_p): Remove.
2815 * src/struniq.h: Likewise.
2816
2817 2002-11-18 Paul Eggert <eggert@twinsun.com>
2818
2819 * data/glr.c (yygetLRActions): Replace `yyindex' with
2820 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
2821 This fixes the regression with Sun ONE Studio 7 cc that I reported in
2822 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
2823
2824 2002-11-18 Akim Demaille <akim@epita.fr>
2825
2826 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
2827 space.
2828 From Tim Van Holder.
2829
2830 2002-11-17 Paul Eggert <eggert@twinsun.com>
2831
2832 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
2833 to "SyntaxError" for consistency with my 2002-11-15 change.
2834
2835 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
2836 not define to {}, since this breaks the common use of `YYDPRINTF
2837 ((...));' if a single statement is desired (e.g. before `else').
2838 Work around GCC warnings by surrounding corresponding calls with
2839 {} if needed.
2840 (yyhasResolvedValue): Remove unused function.
2841 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
2842 loop body.
2843 (yyreportSyntaxError): Renamed from yyreportParseError.
2844 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
2845 All uses changed.
2846 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
2847 extern when possible. Remove unused initializations.
2848
2849 2002-11-16 Akim Demaille <akim@epita.fr>
2850
2851 Augment the similarity between GLR and LALR traces.
2852
2853 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
2854 (YY_REDUCE_PRINT): New.
2855 (yyparse): Use them.
2856 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
2857 YYDPRINT here.
2858 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
2859 state reached after the reduction/recovery, since...
2860 (yyparse, yyprocessOneStack): Report the state we are entering in.
2861
2862 2002-11-16 Akim Demaille <akim@epita.fr>
2863
2864 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
2865 Add support for --trace=skeleton.
2866 * src/scan-skel.l: %option debug.
2867 Scan strings of non-@ or \n instead of character by character.
2868 (scan_skel): Handle trace_skeleton.
2869 (QPUTS): New.
2870 (@output_parser_name@, @output_header_name@): ``Restore'' their
2871 support (used to be M4 macros).
2872 * data/yacc.c: Quote larger chunks, a la glr.c.
2873 * data/lalr1.cc: Likewise.
2874 The header guards are no longer available, so use some other
2875 string than `YYLSP_NEEDED'.
2876
2877 2002-11-16 Akim Demaille <akim@epita.fr>
2878
2879 Make the ``Printers and Destructors'' test more verbose, taking
2880 `yacc.c''s behavior as (possibly wrong) reference.
2881
2882 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
2883 instead of fprint on stdout.
2884 Set and report the last_line of the symbols.
2885 Consistently display values and locations.
2886
2887 2002-11-16 Paul Eggert <eggert@twinsun.com>
2888
2889 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
2890
2891 2002-11-15 Paul Eggert <eggert@twinsun.com>
2892
2893 * tests/actions.at (Actions after errors): New test case.
2894
2895 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
2896 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
2897 tests/action.at, tests/calc.at, tests/conflicts.at,
2898 tests/cxx-type.at, tests/regression.at:
2899 "parse error" -> "syntax error" for POSIX compatibility.
2900 "parsing stack overflow..." -> "parser stack overflow" so
2901 that code matches Bison documentation.
2902
2903 2002-11-15 Akim Demaille <akim@epita.fr>
2904
2905 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
2906 take two BRACED_CODE, not two string_content.
2907 Free the scanner's obstack when we are done.
2908 (code_content): New.
2909 * tests/calc.at: Adjust.
2910 * doc/bison.texinfo: Adjust.
2911 Also, make sure to include the `,' for these declarations.
2912
2913 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
2914
2915 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
2916 definition; avoids potential autoreconf problems.
2917
2918 2002-11-15 Akim Demaille <akim@epita.fr>
2919
2920 Always check the value returned by yyparse.
2921
2922 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
2923 returned by yyparse.
2924 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
2925 Adjust calls.
2926 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
2927 returned by yyparse.
2928
2929 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
2930
2931 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
2932 on input.at test.
2933
2934 2002-11-14 Paul Eggert <eggert@twinsun.com>
2935
2936 * src/output.c (output_skeleton): Call xfopen instead of
2937 duplicating xfopen's body.
2938
2939 Fix bugs reported by Nelson H. F. Beebe in
2940 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
2941
2942 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
2943 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
2944 Group compiler. Instead, use "$CC -E bar.c". Include the .h
2945 file twice in the grammar, as an extra check.
2946
2947 * tests/input.at (Torturing the Scanner): Surround the
2948 backslash-newline tests with "#if 0", to make it less likely that
2949 we'll run into compiler bugs. Bring back solitary \ inside
2950 comment, but add a closing comment to work around HP C bug. Don't
2951 test backslash-newline in C character constant.
2952
2953 2002-11-14 Akim Demaille <akim@epita.fr>
2954
2955 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
2956 status of the compiler.
2957 Calling `exit 1' is no longer needed.
2958 Reported by Nelson H. F. Beebe.
2959
2960 2002-11-14 Akim Demaille <akim@epita.fr>
2961
2962 * tests/atlocal.in (CPPFLAGS): We have config.h.
2963 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
2964 New.
2965 * tests/actions.at, tests/calc.at, tests/conflicts.at,
2966 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
2967 * tests/regression.at, tests/torture.at: Use them for all the
2968 grammars that are to be compiled.
2969 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
2970 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
2971 * doc/bison.texinfo (GLR Parsers): Document `inline'.
2972
2973 2002-11-14 Akim Demaille <akim@epita.fr>
2974
2975 * doc/bison.texinfo: Various formatting changes (alignments in
2976 samples, additional @group/@end group, GCS in samples.
2977 Use @deffn instead of simple @table to define the directives,
2978 macros, variables etc.
2979
2980 2002-11-13 Paul Eggert <eggert@twinsun.com>
2981
2982 Fix some bugs reported by Albert Chin-A-Young in
2983 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
2984
2985 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
2986 -o c"; the HP C compiler chatters during compilation.
2987 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
2988 * tests/headers.at (export YYLTYPE): Likewise.
2989
2990 * tests/input.at (Torturing the Scanner): Remove lines containing
2991 solitary backslashes, as they tickle a bug in the HP C compiler.
2992
2993 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
2994 comments, since they're not portable. Use GNU coding style.
2995
2996 2002-11-13 Akim Demaille <akim@epita.fr>
2997
2998 * data/yacc.c: Leave bigger chunks of quoted text.
2999 (YYDSYMPRINTF): New.
3000 Use it to report symbol activities.
3001 * data/glr.c (YYDSYMPRINTF): New.
3002 Use it.
3003
3004 2002-11-12 Paul Eggert <eggert@twinsun.com>
3005
3006 Version 1.75b.
3007
3008 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
3009 (yyglrReduce): Return yyok, not 0.
3010 This should avoid the enumerated-type warnings reported
3011 by Nelson H. F. Beebe in
3012 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
3013
3014 * lib/bbitset.h (BITSET_INLINE): Remove.
3015 * lib/bitset.h [! BITSET_INLINE]: Remove.
3016 (bitset_set, bitset_reset, bitset_test): Rename local vars
3017 to avoid shadowing warnings by GCC.
3018
3019 * data/glr.c (inline): Remove #define. It's the user's
3020 responsibility to #define it away, just like 'const'.
3021 This fixes one of the bugs reported by Nelson H. F. Beebe in
3022 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
3023
3024 * Makefile.maint (po-check): Scan .l and .y files instead of the
3025 .c and the .h files that they generate. This fixes the bug
3026 reported by Tim Van Holder in:
3027 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
3028 Look for N_ as well as for _. Try to avoid matching #define for
3029 N_ and _.
3030 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
3031 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
3032 * src/scan-gram.l: Revamp regular expressions so that " and '
3033 do not confuse xgettext.
3034
3035 * src/struniq.h (struniq_new): Do not declare the return type
3036 to be 'const'; this violates the C standard.
3037 * src/struniq.c (struniq_new): Likewise.
3038
3039 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
3040
3041 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
3042 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
3043 linker.
3044
3045 2002-11-12 Akim Demaille <akim@epita.fr>
3046
3047 * Makefile.maint: Sync with Autoconf:
3048 (local_updates): New.
3049
3050 2002-11-12 Akim Demaille <akim@epita.fr>
3051
3052 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
3053
3054 2002-11-12 Akim Demaille <akim@epita.fr>
3055
3056 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
3057 locations.
3058
3059 2002-11-12 Akim Demaille <akim@epita.fr>
3060
3061 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
3062 not yyvalue.
3063
3064 2002-11-12 Akim Demaille <akim@epita.fr>
3065
3066 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
3067 Use it to test the GLR parser.
3068
3069 2002-11-12 Akim Demaille <akim@epita.fr>
3070
3071 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
3072 defines it.
3073 * data/glr.c (yystos): New.
3074 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
3075 (YYDSYMPRINT): New.
3076 (yyval): Don't define it, it is handled via M4.
3077 (yyrecoverParseError): Free verbosely the discarded symbols.
3078 * data/yacc.c (yysymprint): Remove, rather...
3079 (b4_yysymprint_generate): invoke.
3080 * data/c.m4 (b4_yysymprint_generate): New.
3081 Accept pointers as arguments, as opposed to the version from
3082 yacc.c.
3083 (b4_yydestruct_generate): Likewise.
3084 * tests/cations.at (Printers and Destructors): Use Bison directives
3085 instead of CPP macros.
3086 Don't rely on internal details.
3087
3088 2002-11-12 Akim Demaille <akim@epita.fr>
3089
3090 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
3091 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
3092 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
3093 it against YYEMPTY and so forth), work on yytoken (i.e., set
3094 it to YYEMPTY etc.).
3095 (yydestruct): Replace with a b4_yydestruct_generate invocation.
3096 (b4_symbol_actions): Remove.
3097 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
3098 for 0, end-of-input.
3099
3100 2002-11-12 Akim Demaille <akim@epita.fr>
3101
3102 * doc/bison.texinfo (Destructor Decl): New.
3103
3104 2002-11-12 Akim Demaille <akim@epita.fr>
3105
3106 * src/tables.c (tables_generate): Use free for pointers that
3107 cannot be NULL, not XFREE.
3108 (pack_vector): Use assert, not fatal, for bound violations.
3109 * src/state.c (state_new): Likewise.
3110 * src/reader.c (reader): Likewise.
3111 * src/lalr.c (set_goto_map): Likewise.
3112 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
3113 the file name.
3114
3115 2002-11-12 Akim Demaille <akim@epita.fr>
3116
3117 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
3118 Restore.
3119 * src/scan-gram.l (last_string): Is global to the file, not to
3120 yylex.
3121 * src/parse-gram.y (input): Don't append the epilogue here,
3122 (epilogue.opt): do it here, and free the scanner's obstack.
3123 * src/reader.c (epilogue_set): Rename as...
3124 (epilogue_augment): this.
3125 * data/c.m4 (b4_epilogue): Defaults to empty.
3126
3127 2002-11-12 Akim Demaille <akim@epita.fr>
3128
3129 * src/getargs.c (long_options): Remove duplicates.
3130 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
3131 Remove.
3132 * doc/bison.rnh: Remove.
3133 * doc/bison.texinfo (VMS Invocation): Remove.
3134
3135 2002-11-12 Akim Demaille <akim@epita.fr>
3136
3137 * src/struniq.h, src/struniq.c (struniq_t): Is const.
3138 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
3139
3140 Use struniq for symbols.
3141
3142 * src/symtab.h (symbol_t): The tag member is a struniq.
3143 (symbol_type_set): Adjust.
3144 * src/symtab.c (symbol_new): Takes a struniq.
3145 (symbol_free): Don't free the tag member.
3146 (hash_compare_symbol_t, hash_symbol_t): Rename as...
3147 (hash_compare_symbol, hash_symbol): these.
3148 Use the fact that tags as struniqs.
3149 (symbol_get): Use struniq_new.
3150 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
3151 Returns a strniq.
3152 * src/reader.h (merger_list, grammar_currentmerge_set): The name
3153 and type members are struniqs.
3154 * src/reader.c (get_merge_function)
3155 (grammar_current_rule_merge_set): Adjust.
3156 (TYPE, current_type): Are struniq.
3157
3158 Use struniq for file names.
3159
3160 * src/files.h, src/files.c (infile): Split into...
3161 (grammar_file, current_file): these.
3162 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
3163 * src/reduce.c (reduce_print): Likewise.
3164 * src/getargs.c (getargs): Likewise.
3165 * src/complain.h, src/complain.c: Likewise.
3166 * src/main.c (main): Call struniqs_new early enough to use it for
3167 file names.
3168 Don't free the input file name.
3169
3170 2002-11-12 Akim Demaille <akim@epita.fr>
3171
3172 * src/symtab.c (symbol_free): Remove dead deactivated code:
3173 type_name are properly removed.
3174 Don't use XFREE to free items that cannot be NULL.
3175 * src/struniq.h, src/struniq.c: New.
3176 * src/main.c (main): Initialize/free struniqs.
3177 * src/parse-gram.y (%union): Add astruniq member.
3178 (yyprint): Adjust.
3179 * src/scan-gram.l (<{tag}>): Return a struniq.
3180 Free the obstack bit that used to store it.
3181 * src/symtab.h (symbol_t): The 'type_name' member is a struniq.
3182
3183 2002-11-11 Paul Eggert <eggert@twinsun.com>
3184
3185 Revamp to fix many (but not all) of the C- and M4-related quoting
3186 problems. Among other things, this fixes the Bison bug reported
3187 by Jan Hubicka when processing the Bash grammar; see:
3188 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
3189
3190 Use new @ escapes consistently. Represent brackets with @{ and @}
3191 rather than @<:@ and @:>@, since this works a bit better with dumb
3192 editors like vi. Represent @ with @@, since @ is now consistently
3193 an escape. Use @oline@ and @ofile@ rather than __oline__ and
3194 __ofile__, to avoid unexpected expansions. Similarly, use @output
3195 rather than #output.
3196
3197 * data/c.m4 (b4_copyright): Omit file name from comment, since
3198 the file name could contain "*/".
3199 (b4_synclines_flag): Don't quote the 2nd argument; it should already
3200 be quoted. All uses changed.
3201
3202 * data/glr.c: Use new @ escapes consistently.
3203 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
3204 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
3205 Remove, since they couldn't handle arbitrary characters in file
3206 names.
3207 * data/lalr1.cc: Likewise.
3208 * data/yacc.c: Likewise.
3209
3210 * src/files.c (output_infix): Remove; all uses removed.
3211 * src/files.h: Likewise.
3212
3213 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
3214 mishandled funny characters in file names, and anyway it isn't
3215 needed any more.
3216 * data/yacc.c: Likewise.
3217 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
3218
3219 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
3220 * data/yacc.c: Likewise.
3221
3222 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
3223 strings now.
3224 (muscle_init): Quote filename as a C string.
3225 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
3226 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
3227 * src/output.c (escaped_file_name_output): New function.
3228 (prepare_symbols): Quote tokens for M4.
3229 (prepare): Don't insert output_infix, output_prefix,
3230 output_parser_name, output_header_name; this is now down by scan-skel.
3231 Insert skeleton as a C string.
3232
3233 * src/output.c (user_actions_output, symbol_destructors_output,
3234 symbol_printers_output): Quote filenames for C and M4.
3235 * src/reader.c (prologue_augment, epilogue_set): Likewise.
3236
3237 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
3238 escapes other than \\ and \'; this simplifies the code.
3239 (<SC_STRING>): Likewise, for \\ and \".
3240 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
3241 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
3242 Use new escapes @{ and @} for [ and ].
3243
3244 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
3245 them with auto vars.
3246 Switch to new escape scheme, where @ is the escape character uniformly.
3247 Abort if a stray escape character is found. Avoid unbounded input
3248 buffer when parsing non-escaped text.
3249
3250 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
3251 __oline__, #output, $@, and @{ do not have unintended meanings.
3252
3253 2002-11-09 Paul Eggert <eggert@twinsun.com>
3254
3255 Fix the test failure due to GCC warnings described in
3256 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
3257 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
3258 evaluate to 0 if it's impossible for NINF to be in the respective
3259 table.
3260 (yygetLRActions, yyrecoverParseError): Use them.
3261
3262 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
3263 counted in the token inserted at end of file. Now takes
3264 location_t *, not location_t, so that the location can be
3265 adjusted. All uses changed.
3266
3267 * tests/regression.at (Invalid inputs): Adjust wording in
3268 diagnostic to match the new behavior.
3269
3270 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
3271 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
3272 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
3273 abort ();'. This reduces the runtime of the "Many lookaheads"
3274 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
3275 GCC 3.2.
3276
3277 2002-11-07 Paul Eggert <eggert@twinsun.com>
3278
3279 * src/parse-gram.y (CHARACTER): Remove unused token.
3280 All uses removed.
3281
3282 * src/scan-gram.l: Remove stack option. We no longer use the
3283 stack, since the stack was never deeper than 1; instead, use the
3284 new auto var c_context to record the stacked value.
3285
3286 Remove nounput option. At an unexpected end of file, we now unput
3287 the minimal input necessary to end cleanly; this simplifies the
3288 code.
3289
3290 Avoid unbounded token sizes where this is easy.
3291
3292 (unexpected_end_of_file): New function.
3293 Use it to systematize the error message on unexpected EOF.
3294 (last-string): Now auto, not static.
3295 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
3296 (scanner_last_string_free): Remove; not used.
3297 (percent_percent_count): Move decl to just before use.
3298 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
3299 not the (never otherwised-used) CHARACTER.
3300
3301 2002-11-07 Akim Demaille <akim@epita.fr>
3302
3303 Let yyerror always receive the msg as last argument, so that
3304 yyerror can be variadic.
3305
3306 * data/yacc.c (b4_yyerror_args): New.
3307 Use it when calling yyerror.
3308 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
3309 Use it when calling yyerror.
3310 * doc/bison.texinfo (Error Reporting): Adjust.
3311 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
3312 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
3313
3314 2002-11-06 Akim Demaille <akim@epita.fr>
3315
3316 #line should have quoted strings.
3317 Ideally, this should be done by m4_quotearg.
3318
3319 * src/scan-skel.l: Include quotearg.h.
3320 Quote __ofile__.
3321 * src/output.c (symbol_printers_output)
3322 (symbol_destructors_output): Quote the file name.
3323
3324 2002-11-06 Akim Demaille <akim@epita.fr>
3325
3326 * tests/regression.at (Invalid inputs): Adjust to the recent
3327 messages.
3328
3329 2002-11-06 Akim Demaille <akim@epita.fr>
3330
3331 Restore --no-lines.
3332 Reported by Jim Kent.
3333
3334 * data/c.m4 (b4_syncline): New.
3335 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
3336 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
3337 * src/output.c (user_actions_output): Likewise.
3338 (prepare): Define 'b4_synclines_flag'.
3339 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
3340
3341 2002-11-06 Akim Demaille <akim@epita.fr>
3342
3343 * src/main.c (main): Free `infile'.
3344 * src/scan-gram.l (handle_syncline): New.
3345 Recognize `#line'.
3346 * src/output.c (user_actions_output, symbol_destructors_output)
3347 (symbol_printers_output): Use the location's file name, not
3348 infile.
3349 * src/reader.c (prologue_augment, epilogue_set): Likewise.
3350
3351 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
3352
3353 * src/tables.c (matching_state): Don't allow states to match if
3354 either has GLR conflict entries.
3355
3356 2002-11-05 Paul Eggert <eggert@twinsun.com>
3357
3358 * src/scan-gram.l: Use more accurate diagnostics, e.g.
3359 "integer out of range" rather than "invalid value".
3360 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
3361 accordingly.
3362
3363 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
3364 Also, remove one static variable in the scanner.
3365
3366 * src/scan-gram.l (braces_level): Now auto, not static.
3367 Initialize to zero if the compiler is being picky.
3368 (INITIAL): Clear braces_level instead of incrementing it.
3369 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
3370 as POSIX 1003.1-2001 requires.
3371 * src/system.h (IF_LINT): New macro, taken from coreutils.
3372 * configure.ac: Define "lint" if --enable-gcc-warnings.
3373
3374 2002-11-05 Akim Demaille <akim@epita.fr>
3375
3376 * src/scan-gram.l: When it starts with `%', complain about the
3377 whole directive, not just that `invalid character: %'.
3378
3379 2002-11-04 Akim Demaille <akim@epita.fr>
3380
3381 * Makefile.maint: Update from Autoconf.

3388 Have yyerror `use' its arguments.
3389 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
3390 returns true when location & yacc & pure & parse-param.
3391 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
3392
3393 2002-11-04 Akim Demaille <akim@epita.fr>
3394
3395 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
3396 clashes.
3397 * src/scan-gram.l: Use [\'] instead of ['] to pacify
3398 font-lock-mode.
3399 Use complain_at.
3400 Use quote, not quote_n since LOCATION_PRINT no longer uses the
3401 slot 0.
3402
3403 2002-11-03 Paul Eggert <eggert@twinsun.com>
3404
3405 * src/reader.c (get_merge_function, grammar_current_rule_check):
3406 Use consistent diagnostics for reporting type name clashes.
3407 Quote the types with <>, for consistency with Yacc.
3408 * tests/input.at (Type Clashes): Adjust to diagnostic changes.

3419 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
3420 (b4_lpure_formals): New.
3421 Use b4_identification.
3422 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
3423 b4_user_formals and b4_user_args.
3424 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
3425 (yyreportAmbiguity): When using a pure parser, also need
3426 the location, and the parse-params.
3427 Adjust callers.
3428 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
3429 When using a pure parser, also need the parse-params.
3430 Adjust callers.
3431 * tests/calc.at: Test pure (%pure-parser) and absolutely pure

3434 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
3435 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
3436 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
3437 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
3438 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
3439 * doc/bison.texinfo: Untabify the whole file.
3440 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
3441 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
3442 (Error Reporting): Adjust to these new directives.
3443 Document %error-verbose, deprecate YYERROR_VERBOSE.
3444
3445 2002-11-03 Akim Demaille <akim@epita.fr>
3446
3447 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
3448 AT_CHECK_CALC_GLR invocations to use % directives, instead of
3449 command line options.
3450 * tests/cxx-type.at: Formatting changes.
3451
3452 2002-11-03 Paul Eggert <eggert@twinsun.com>
3453
3454 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
3455 to count columns correctly, and to check for invalid inputs.
3456
3457 Use mbsnwidth to count columns correctly. Account for tabs, too.
3458 Include mbswidth.h.
3459 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
3460 (extend_location): New function.
3461 (YY_LINES): Remove.
3462
3463 Handle CRLF in C code rather than in Lex code.
3464 (YY_INPUT): New macro.
3465 (no_cr_read): New function.
3466
3467 Scan UCNs, even though we don't fully handle them yet.
3468 (convert_ucn_to_byte): New function.
3469
3470 Handle backslash-newline correctly in C code.
3471 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
3472 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
3473 all uses changed.
3474 (tag, splice): New EREs. Do not allow NUL or newline in tags.
3475 Use {splice} wherever C allows backslash-newline.
3476 YY_STEP after space, newline, vertical-tab.
3477 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
3478
3479 (letter, id): Don't assume ASCII; e.g., spell out a-z.
3480
3481 ({int}, handle_action_dollar, handle_action_at): Check for integer
3482 overflow.
3483
3484 (YY_STEP): Omit trailing semicolon, so that it's more like C.
3485
3486 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
3487 as well as \000. Check for UCHAR_MAX, not 255.
3488 Allow \x with an arbitrary positive number of digits, as in C.
3489 Check for overflow here.
3490 Allow \? and UCNs, for compatibility with C.
3491
3492 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
3493 with quote slot used by complain_at.
3494
3495 * tests/input.at: Add tests for backslash-newline, m4 quotes
3496 in symbols, long literals, and funny escapes in strings.
3497
3498 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
3499 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
3500 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
3501 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
3502 * m4/mbswidth.m4: New file, from GNU coreutils.
3503
3504 * doc/bison.texinfo (Grammar Outline): Document // comments.
3505 (Symbols): Document that trigraphs have no special meaning in Bison,
3506 nor is backslash-newline allowed.
3507 (Actions): Document that trigraphs have no special meaning.
3508
3509 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
3510 no longer used.
3511
3512 2002-11-02 Paul Eggert <eggert@twinsun.com>
3513
3514 * src/reader.c: Don't include quote.h; not needed.
3515 (get_merge_function): Reword warning to be consistent with
3516 type clash diagnostic in grammar_current_rule_check.
3517
3518 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
3519 bug in trigraph handling.
3520
3521 * src/output.c (prepare_symbols): When printing token names,
3522 escape "[" as "@<:@" and likewise for "]".
3523
3524 * src/system.h (errno): Remove declaration, as we are now
3525 assuming C89 or better, and C89 guarantees errno.
3526
3527 2002-10-30 Paul Eggert <eggert@twinsun.com>
3528
3529 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
3530 Check for close failures.
3531 * src/files.h (xfclose): Return void, not int, since it always
3532 returned zero.
3533 * src/files.c (xfclose): Likewise. Report I/O error if ferror
3534 indicates one.
3535 * src/output.c (output_skeleton): Use xfclose rather than fclose
3536 and ferror. xfclose now checks ferror.
3537
3538 * data/glr.c (YYLEFTMOST_STATE): Remove.
3539 (yyreportTree): Use a stack-based leftmost state. This avoids
3540 our continuing battles with bogus warnings about initializers.
3541
3542 2002-10-30 Akim Demaille <akim@epita.fr>
3543
3544 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
3545 #if.
3546
3547 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
3548
3549 * tests/glr-regr1.at: New test for reported regressions.
3550 * tests/testsuite.at: Add glr-regr1.at test.
3551 * tests/Makefile.am: Add glr-regr1.at test.
3552
3553 2002-10-24 Paul Eggert <eggert@twinsun.com>
3554
3555 Version 1.75a.
3556
3557 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
3558 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
3559 we use malloc. Don't assume 'A' through 'Z' are contiguous.
3560 Don't assume strdup exists; POSIX says its an XSI extension.
3561 Check for buffer overflow on input.
3562
3563 2002-10-24 Akim Demaille <akim@epita.fr>
3564
3565 * src/output.c (output_skeleton): Don't disable M4sugar comments
3566 too soon: it results in comments being expanded.
3567 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
3568 first output.
3569
3570 2002-10-24 Akim Demaille <akim@epita.fr>
3571
3572 * data/yacc.c (m4_int_type): New.
3573 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
3574 char' as only yacc.c wants K&R portability.
3575 * data/glr.c (yysigned_char): Remove.
3576 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
3577 Reported by Quoc Peyrot.
3578
3579 2002-10-23 Paul Eggert <eggert@twinsun.com>
3580
3581 * src/main.c (main): With --trace=time, report times even if a
3582 non-fatal error occurs. Formerly, the times were reported in some
3583 such cases but not in others.
3584 * src/reader.c (reader): Just return if a complaint has been issued,
3585 instead of exiting, so that 'main' can report times.
3586
3587 2002-10-22 Akim Demaille <akim@epita.fr>
3588
3589 * src/system.h: Include sys/types.
3590 Reported by Bert Deknuydt.
3591
3592 2002-10-23 Paul Eggert <eggert@twinsun.com>
3593
3594 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
3595 Suggested by Art Haas.
3596
3597 2002-10-22 Paul Eggert <eggert@twinsun.com>
3598
3599 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
3600 decl; not needed any more.
3601 * src/main.c (main): Use return to exit, undoing yesterday's change.
3602 The last OS that we could find where this wouldn't work is
3603 SunOS 3.5, and that's too old to worry about now.
3604
3605 * data/glr.c (struct yyltype): Define members even when not
3606 doing locations. This is more consistent with yacc.c, and it
3607 works around the following bug reports:
3608 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
3609 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
3610
3611 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
3612 @acronym consistently. Standardize on "Yacc" instead of "YACC",
3613 "Algol" instead of "ALGOL". Give a bit more history about BNF.
3614
3615 2002-10-22 Akim Demaille <akim@epita.fr>
3616
3617 * data/README: New.
3618
3619 2002-10-21 Paul Eggert <eggert@twinsun.com>
3620
3621 Be consistent about 'bool'; the old code used an enum in one
3622 module and an int in another, and this violates the C standard.
3623 * m4/stdbool.m4: New file, from coreutils 4.5.3.
3624 * configure.ac (AC_HEADER_STDBOOL): Add.
3625 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
3626 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
3627 * src/symtab.c (hash_compare_symbol_t): Likewise.
3628 * src/system.h (bool, false, true): Use a definition consistent
3629 with ../lib/hash.c. All uses changed.
3630
3631 * src/complain.c (warning_issued): Renamed from warn_message_count,
3632 so that we needn't worry about integer overflow (!).
3633 Now of type bool. All uses changed.
3634 (complaint_issued): Renamed from complain_message_count; likewise.
3635
3636 * src/main.c (main): Use exit to exit with failure.
3637
3638 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
3639 rather than 1 and 0.
3640 * src/main.c (main): Likewise.
3641 * src/getargs.c (getargs): Likewise.
3642 * src/reader.c (reader): Likewise.
3643
3644 * src/getarg.c (getargs): Remove duplicate code for
3645 "Try `bison --help'".
3646
3647 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
3648 What was that "2" for?
3649
3650 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
3651 * src/getargs.c (usage): Likewise.
3652
3653 * src/getargs.c (getargs): When there are too few operands, report
3654 the last one. When there are too many, report the first extra
3655 one. This is how diffutils does it.
3656
3657 2002-10-20 Paul Eggert <eggert@twinsun.com>
3658
3659 Remove K&R vestiges.
3660 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
3661 * src/complain.c (VA_START): Remove. Assume prototypes.
3662 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
3663 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
3664 fatal): Assume prototypes.
3665 * src/complain.h: Assume prototypes.
3666 * src/system.h (PARAMS): Remove.
3667 Include <limits.h> unconditionally, since it's guaranteeed even
3668 for a freestanding C89 compiler.
3669 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
3670 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
3671
3672 2002-10-20 Akim Demaille <akim@epita.fr>
3673
3674 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
3675 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
3676 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
3677 (yyresolveStates, yyresolveAction, yyresolveStack)
3678 (yyprocessOneStack): Use them.
3679 (yy_reduce_print): New.
3680 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
3681
3682 2002-10-20 Akim Demaille <akim@epita.fr>
3683
3684 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
3685 arguments and output `void'.
3686 (b4_c_function): Rename as...
3687 (b4_c_function_def): this.
3688 (b4_c_function_decl, b4_c_ansi_function_def)
3689 (b4_c_ansi_function_decl): New.
3690 Change the interpretation of the arguments: before `int, foo', now
3691 `int foo, foo'.
3692 * data/yacc.c (yyparse): Prototype and define thanks to these.
3693 Adjust b4_c_function_def uses.
3694 * data/glr.c (yyparse): Likewise, but ANSI only.
3695
3696 2002-10-20 Akim Demaille <akim@epita.fr>
3697
3698 * src/output.c (prepare): Move the definition of `tokens_number',
3699 `nterms_number', `undef_token_number', `user_token_number_max'
3700 to...
3701 (prepare_tokens): Here.
3702 (prepare_tokens): Rename as...
3703 (prepare_symbols): this.
3704 (prepare): Move the definition of `rules_number' to...
3705 (prepare_rules): here.
3706 (prepare): Move the definition of `last', `final_state_number',
3707 `states_number' to...
3708 (prepare_states): here.
3709 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
3710
3711 2002-10-20 Akim Demaille <akim@epita.fr>
3712
3713 * src/tables.h, src/tables.c, src/output.c: Comment changes.
3714
3715 2002-10-20 Akim Demaille <akim@epita.fr>
3716
3717 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
3718 * data/c.m4: here.
3719
3720 2002-10-20 Akim Demaille <akim@epita.fr>
3721
3722 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
3723 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
3724 `pair'.
3725 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
3726 `name' to...
3727 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
3728 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
3729 These.
3730
3731 2002-10-19 Paul Eggert <eggert@twinsun.com>
3732
3733 Do not create a temporary file, as that involves security and
3734 cleanup headaches. Instead, use a pair of pipes.
3735 Derived from a suggestion by Florian Krohm.
3736 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
3737 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
3738 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
3739 (BISON_PREREQ_SUBPIPE): Add.
3740 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
3741 Add subpipe.h, subpipe.c.

3743 * po/POTFILES.in: Add lib/subpipe.c.
3744 * src/output.c: Include "subpipe.h".
3745 (m4_invoke): Remove decl.
3746 (scan_skel): New decl.
3747 (output_skeleton): Use pipe rather than temporary file for m4 input.
3748 Check that m4sugar.m4 is readable, to avoid deadlock.
3749 Check for pipe I/O error.
3750 * src/scan-skel.l (readpipe): Remove decl.
3751 (scan_skel): New function, to be used in place of m4_invoke.
3752 Read from stream rather than file.
3753
3754 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
3755 float, as this generates a warning on Solaris 8 + GCC 3.2 with
3756 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
3757 this generates a more-accurate value anyway.
3758
3759 * lib/timevar.c (timervar_accumulate): Rename locals to
3760 avoid confusion with similarly-named more-global.
3761 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
3762
3763 * src/output.c (prepare): Use xstrdup to convert char const *
3764 to char *, to avoid GCC warning.
3765
3766 2002-10-19 Akim Demaille <akim@epita.fr>
3767
3768 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
3769 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
3770 Use them to have `calc.y' ready for %pure-parser.
3771 * data/yacc.c (YYLEX): Pass a yylex return type to
3772 b4_c_function_call.
3773
3774 2002-10-19 Akim Demaille <akim@epita.fr>
3775
3776 Prototype support of %lex-param and %parse-param.
3777
3778 * src/parse-gram.y: Add the definition of the %lex-param and
3779 %parse-param tokens, plus their rules.
3780 Drop the `_' version of %glr-parser.
3781 Add the "," token.
3782 * src/scan-gram.l (INITIAL): Scan them.
3783 * src/muscle_tab.c: Comment changes.
3784 (muscle_insert, muscle_find): Rename `pair' as `probe'.
3785 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
3786 (muscle_entry_s): The `value' member is no longer const.
3787 Adjust all dependencies.
3788 * src/muscle_tab.c (muscle_init): Adjust: use
3789 MUSCLE_INSERT_STRING.
3790 Initialize the obstack earlier.
3791 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
3792 (muscle_pair_list_grow): New.
3793 * data/c.m4 (b4_c_function_call, b4_c_args): New.
3794 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
3795 * tests/calc.at: Use %locations, not --locations.
3796 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
3797
3798 2002-10-19 Akim Demaille <akim@epita.fr>
3799
3800 * src/getargs.c (usage): Take status as argument and exit
3801 accordingly.
3802 Report the traditional `Try ... --help' message when status != 0.
3803 (usage, version): Don't take a FILE * as arg, it is pointless.
3804 (getargs): When there is an incorrect number of arguments, make it
3805 an error, and report it GNUlically thanks to `usage ()'.
3806
3807 2002-10-18 Paul Eggert <eggert@twinsun.com>
3808
3809 * data/glr.c (yyreportParseError): Don't assume that sprintf
3810 yields the length of the printed string, as this is not true
3811 on SunOS 4.1.4. Reported by Peter Klein.
3812
3813 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
3814 * tests/conflicts.at (%nonassoc and eof): Likewise.
3815 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
3816

3820 * src/getargs.c (trace_types, trace_args): Adjust.
3821 * src/reader.c (grammar_current_rule_prec_set)
3822 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
3823 Standardize error messages.
3824 And s/@prec/%prec/!
3825 (reader): Use trace_flag to enable scanner/parser debugging,
3826 instead of an adhoc scheme.
3827 * src/scan-gram.l: Remove trailing debugging code.
3828
3829 2002-10-16 Paul Eggert <eggert@twinsun.com>
3830
3831 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
3832 MUSCLE_TAB_H.
3833
3834 * NEWS: Officially drop support for building Bison with K&R C,
3835 since it didn't work anyway and it's not worth worrying about.
3836 * Makefile.maint (wget_files): Remove ansi2knr.c.
3837 (ansi2knr.c-url_prefix): Remove.
3838 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

3840 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
3841
3842 2002-10-15 Paul Eggert <eggert@twinsun.com>
3843
3844 Stop using the "enum_" trick for K&R-style function definitions;
3845 it confused me, and I was the author! Instead, assume that people
3846 who want to use K&R C compilers (when using these modules in GCC,
3847 perhaps?) will run ansi2knr.
3848
3849 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
3850 All uses of "enum_" changed to "enum ".
3851 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

3862 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
3863 Use function prototypes; this removes the need for declaring
3864 static functions simply to provide their prototypes.

3921
3922 2002-10-14 Akim Demaille <akim@epita.fr>
3923
3924 * tests/Makefile.am (maintainer-check-posix): New.
3925
3926 2002-10-14 Akim Demaille <akim@epita.fr>
3927
3928 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
3929 member.
3930
3931 2002-10-14 Akim Demaille <akim@epita.fr>
3932
3933 * src/tables.c (table_ninf_remap): base -> tab.
3934 Reported by Matt Rosing.
3935
3936 2002-10-14 Paul Eggert <eggert@twinsun.com>
3937
3938 * tests/action.at, tests/calc.at, tests/conflicts.at,
3939 tests/cxx-type.at, tests/headers.at, tests/input.at,
3940 tests/regression.at, tests/synclines.at, tests/torture.at:
3941 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
3942 so that the tests still work even if POSIXLY_CORRECT is set.
3943 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
3944
3945 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
3946 for portability to K&R hosts. Fix typo: signed char is guaranteed
3947 only to 127, not to 128.
3948 * data/glr.c (yysigned_char): New type.
3949 * data/yacc.c (yysigned_char): Likewise.
3950 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
3951
3952 2002-10-13 Paul Eggert <eggert@twinsun.com>
3953
3954 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
3955 true due to limited range of data type" warning from GCC.
3956
3957 * data/c.m4 (b4_token_defines): Protect against double-inclusion
3958 by wrapping enum yytokentype's definition inside #ifndef
3959 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
3960
3961 2002-10-13 Akim Demaille <akim@epita.fr>
3962
3963 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
3964 Un yy- yyrhs to avoid the name clash with the global YYRHS.
3965
3966 2002-10-13 Akim Demaille <akim@epita.fr>
3967
3968 * Makefile.maint: Update from Autoconf 2.54.

3970
3971 2002-10-13 Akim Demaille <akim@epita.fr>
3972
3973 * src/print.c (print_state): Separate the list of solved conflicts
3974 from the other items.
3975 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
3976
3977 2002-10-13 Akim Demaille <akim@epita.fr>
3978
3979 Let nondeterministic skeletons be usable with deterministic
3980 tables.
3981
3982 With the patch, GAWK compiled by GCC without -O2 passes its test
3983 suite using a GLR parser driven by LALR tables. It fails with -O2
3984 because `struct stat' gives two different answers on my machine:
3985 88 (definition of an auto var) and later 96 (memset on this var).
3986 Hence the stack is badly corrumpted. The headers inclusion is to
3987 blame: if I move the awk.h inclusion before GLR's system header
3988 inclusion, the two struct stat have the same size.
3989
3990 * src/tables.c (pack_table): Always create conflict_table.
3991 (token_actions): Always create conflict_list.
3992 * data/glr.c (YYFLAG): Remove, unused.
3993
3994 2002-10-13 Akim Demaille <akim@epita.fr>
3995
3996 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
3997 (O0FLAGS): New.
3998 (VALGRIND, GXX): New.
3999 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
4000 * tests/bison.in: Run $PREBISON a pre-command.
4001 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
4002 (maintainer-check-g++): New.
4003 * Makefile.am (maintainer-check): New.
4004
4005 2002-10-13 Akim Demaille <akim@epita.fr>
4006
4007 * data/glr.c: Formatting changes.
4008 Tweak some trace messages to match yacc.c's.
4009
4010 2002-10-13 Akim Demaille <akim@epita.fr>
4011
4012 GLR parsers sometimes raise parse errors instead of performing the
4013 default reduction.
4014 Reported by Charles-Henry de Boysson.
4015
4016 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
4017 check the length of the traces when %glr.
4018 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
4019 GLR's traces.
4020 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
4021 Test GLR parsers.
4022 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
4023 (yyltype): Remove the yy prefix from the member names.
4024 (yytable): Complete its comment.
4025 (yygetLRActions): Map error action number from YYTABLE from
4026 YYTABLE_NINF to 0.
4027 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
4028 (which was a bug: it should have been YYTABEL_NINF, and yet it was
4029 not satisfying as we could compare an YYACTION computed from
4030 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
4031 only value for error actions.
4032 (yyreportParseError): In verbose parse error messages, don't issue
4033 `error' in the list of expected tokens.
4034 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
4035 next action to perform to match glr.c's decoding.
4036 (yytable): Complete its comment.
4037
4038 2002-10-13 Paul Eggert <eggert@twinsun.com>
4039
4040 Fix problem reported by Henrik Grubbstroem in
4041 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
4042 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
4043 because the Bison parser reads the second action before reducing
4044 the first one.
4045 * src/scan-gram.l (rule_length): New static var.
4046 Use it to keep track of the rule length in the scanner, since
4047 we can't expect the parser to be in lock-step sync with the scanner.
4048 (handle_action_dollar, handle_action_at): Use this var.
4049 * tests/actions.at (Exotic Dollars): Test for the problem.
4050
4051 2002-10-12 Paul Eggert <eggert@twinsun.com>
4052
4053 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
4054 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
4055 Include <sys/time.h> when checking for clock_t and struct tms.
4056 Use same include order as source.
4057 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
4058 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
4059
4060 * lib/timevar.c: Update copyright date and clarify comments.
4061 (get_time) [IN_GCC]: Keep the GCC version for reference.
4062
4063 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
4064 GCC version as of today, then merge Bison's changes.
4065 Change "GCC" to "Bison" in copyright notice. timevar.def's
4066 author is Akim, so change that too.
4067
4068 * src/reader.c (grammar_current_rule_check):
4069 Don't worry about the default action if $$ is untyped.
4070 Prevents bogus warnings reported by Jim Gifford in
4071 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
4072
4073 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
4074 * data/glr.c, data/lalr1.cc, data/yacc.c:
4075 Output token definitions before the first part of user declarations.
4076 Fixes compatibility problem reported by Jim Gifford for kbd in
4077 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
4078
4079 2002-10-11 Paul Eggert <eggert@twinsun.com>
4080
4081 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
4082 (yyparse): here. This undoes some of the 2002-07-25 change.
4083 Compatibility problem reported by Ralf S. Engelschall with
4084 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
4085
4086 2002-10-11 Akim Demaille <akim@epita.fr>
4087
4088 * tests/regression.at Characters Escapes): New.
4089 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
4090 characters.
4091 Reported by Jan Nieuwenhuizen.
4092
4093 2002-10-11 Akim Demaille <akim@epita.fr>

4097 2002-10-10 Paul Eggert <eggert@twinsun.com>
4098
4099 Portability fixes for bitsets; this also avoids several GCC
4100 warnings.
4101
4102 * lib/abitset.c: Include <stddef.h>, for offsetof.
4103 * lib/lbitset.c: Likewise.
4104
4105 * lib/abitset.c (abitset_bytes): Return a size that is aligned
4106 properly for vectors of objects. Do not assume that adding a
4107 header size to a multiple of a word size yields a value that is
4108 properly aligned for the whole union.
4109 * lib/bitsetv.c (bitsetv_alloc): Likewise.
4110
4111 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
4112 unique names for structures.
4113 * lib/ebitset.c (ebitset_bytes): Likewise.
4114 * lib/lbitset.c (lbitset_bytes): Likewise.
4115
4116 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,

4121 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
4122 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
4123 to improve the type-checking that GCC can do.
4124 * lib/bitset.c (bitset_op4_cmp): Likewise.
4125 * lib/bitset_stats.c (bitset_stats_count,
4126 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,

4133 bitset_stats_andn_or_cmp, bitset_stats_or_and,
4134 bitset_stats_or_and_cmp): Likewise.
4135 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
4136 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
4137 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
4138 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
4139
4140 * lib/abitset.h: Include bitset.h, not bbitset.h.
4141 * lib/ebitset.h: Likewise.
4142 * lib/lbitset.h: Likewise.
4143
4144 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
4145 All instances of parameters of type enum bitset_opts are now of
4146 type enum_bitset_opts, to conform to the C Standard, and similarly
4147 for enum_bitset_type.
4148 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
4149 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
4150
4151 Do not use "struct bitset_struct" to mean different things in
4152 different modules. Not only is this confusing, it violates
4153 the C Standard, which requires that structure types in different
4154 modules must be compatible if one is to be passed to the other.
4155 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
4156 All instances of "struct bitset_struct *" replaced with "bitset".
4157 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
4158 (union bitset_union, struct abitset_struct, struct ebitset_struct,
4159 struct lbitset_struct, struct bitset_stats_struct): New types.
4160 All uses of struct bitset_struct changed to union bitset_union,

4173 function must be called with a type that is compatible with its
4174 definition.
4175 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):

4199
4200 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
4201 the same width as int. This reapplies a hunk of the 2002-08-12 patch
4202 <http://mail.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
4203 which was inadvertently undone by the 2002-09-30 patch.
4204 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
4205 the same width as int.
4206

4214 fixes.
4215 (Symbols): Mention that any negative value returned from yylex
4216 signifies end-of-input. Warn about negative chars. Mention
4217 the portable Standard C character set.
4218
4219 The GNU coding standard says CFLAGS and YFLAGS are reserved
4220 for the installer to set.
4221 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.

4307 to BITSET_WINDEX_MAX.
4308
4309 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
4310 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

4410
4411 * doc/bison.texinfo (Conditions): Make explicit that the GPL
4412 exception applies only to yacc.c. This is a modification of a
4413 patch originally suggested by Akim Demaille.
4414
4415 2002-09-06 Akim Demaille <akim@epita.fr>
4416

4462 functions are not portable. Do not assume size_t is the
4463 same width as int.
4464 (yypstates): Do not assume that ptrdiff_t is the same width
4465 as int, and similarly for yyposn and YYINDEX.
4466
4467 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

4504 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
4505
4506 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
4507 PROTOTYPES to check for prototypes, and "defined __STDC__" to
4508 check for void *.
4509
4510 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
4511 size_t; the old version tried to do this but casted improperly.
4512 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
4513 (bitset_test): Now returns int, not unsigned long.
4514

4516 (_): New macro.
4517 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
4518 name locals "index", as it generates unnecessary warnings on some
4519 hosts that have an "index" function.

4522 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

4543 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,

4545 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
4546 manual recommends.
4547 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
4548
4549 * src/complain.c (strerror_r): Remove decl; not needed.
4550 (strerror): Use same pattern as ../lib/error.c.
4551
4552 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
4553
4554 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
4555
4556 * src/main.c (main): Cast result of bindtextdomain and textdomain
4557 to void, to avoid a GCC warning when --disable-nls is in effect.
4558
4559 * src/scan-gram.l: Use strings rather than escapes when possible,
4560 to minimize the number of warnings from xgettext.
4561 (handle_action_dollar, handle_action_at): Don't use isdigit,
4562 as it mishandles negative chars and it may not work as expected
4563 outside the C locale.
4564
4565 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
4566 this is a GCC extension and is not portable to other compilers.
4567

4584 Use it for the two large tests.

4645 2002-08-01 Akim Demaille <akim@epita.fr>
4646
4647 * lib/timevar.c (get_time): Include children time.

4748 different: save its reduction (accept) instead of having a state
4749 without any action (no shift or goto, no reduce).
4750 Note: the final state is now a ``regular'' state, i.e., the
4751 parsers now contain `reduce 0' as default reduction.

4753 final_state, they still will not reduce rule 0.

4796 2002-07-26 Akim Demaille <akim@epita.fr>
4797
4798 * src/reader.h, src/reader.c (gram_error): ... can't get
4799 yycontrol without making too strong assumptions on the parser
4800 itself.
4801 * src/output.c (prepare_tokens): Use the real 0th value of
4802 token_translations instead of `0'.
4803 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
4804 visible here.
4805 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
4806 for the time being: %locations ought to provide it to yyerror.
4807
4808 2002-07-25 Akim Demaille <akim@epita.fr>
4809
4810 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

4823 Adjust to `derive' now containing possibly 0.
4824 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
4825 Handle the `- 1' part in rule numbers from/to item numbers.

6343
6344 * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
6345 (parse_guard): Rename the formal argument `stack_offset' as
6346 `rule_length', which is more readable.
6347 Adjust callers.
6348 (copy_at, copy_dollar): Instead of outputting the hard coded
6349 values of $$, $n and so forth, output invocation to b4_lhs_value,
6350 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
6351 Note: this patch partially drops `semantic-parser' support: it
6352 always does `rule_length - n', where semantic parsers ought to
6353 always use `-n'.
6354 * data/bison.simple, data/bison.c++ (b4_lhs_value)
6355 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

6399 Reported by Paul Eggert.
6400
6401 2002-04-24 Robert Anisko <robert@lrde.epita.fr>
6402
6403 * tests/calc.at: Exercise prologue splitting.
6404
6405 * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
6406 `b4_post_prologue' instead of `b4_prologue'.
6407
6408 * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
6409 muscles.
6410 (output): Free pre_prologue_obstack and post_prologue_obstack.
6411 * src/files.h, src/files.c (attrs_obstack): Remove.
6412 (pre_prologue_obstack, post_prologue_obstack): New.
6413 * src/reader.c (copy_definition): Add a parameter to specify the
6414 obstack to fill, instead of using attrs_obstack unconditionally.
6415 (read_declarations): Pass pre_prologue_obstack to copy_definition if
6416 `%union' has not yet been seen, pass post_prologue_obstack otherwise.

6419
6420 * data/bison.simple: Remove unnecessary commentary and white
6421 space differences from 1_29-branch.

6423
6424 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
6425 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
6426 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
6427 constructors or destructors.
6428
6429 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
6430

6456 * tests/regression.at (Web2c Actions): Adjust.
6457
6458 2002-04-22 Akim Demaille <akim@epita.fr>
6459
6460 * src/reader.c (token_translations_init): 256 is now the default
6461 value for the error token, i.e., it will be assigned another
6462 number if the user assigned 256 to one of her tokens.
6463 (reader): Don't force 256 to error.
6464 * doc/bison.texinfo (Symbols): Adjust.
6465 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
6466 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
6467 etc. instead of 10, 20, 30 (which was used to `jump' over error
6468 (256) and undefined (2)).
6469
6470 2002-04-22 Akim Demaille <akim@epita.fr>
6471
6472 Propagate more token_number_t.

6487
6488 2002-04-19 Akim Demaille <akim@epita.fr>
6489
6490 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
6491 as Lex/Flex'.
6492 (Debugging): More details about enabling the debugging features.
6493 (Table of Symbols): Describe $$, $n, @$, and @n.
6494 Suggested by Tim Josling.
6495
6496 2002-04-19 Akim Demaille <akim@epita.fr>
6497
6498 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
6499
6500 2002-04-10 Akim Demaille <akim@epita.fr>
6501
6502 * src/system.h: Rely on HAVE_LIMITS_H.
6503 Suggested by Paul Eggert.
6504
6505 2002-04-09 Akim Demaille <akim@epita.fr>
6506
6507 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
6508 full stderr, and strip it according to the bison options, instead
6509 of composing the error message from different bits.
6510 This makes it easier to check for several error messages.
6511 Adjust all the invocations.
6512 Add an invocation exercising the error token.
6513 Add an invocation demonstrating a stupid error message.
6514 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
6515 Adjust the tests.
6516 Error message are for stderr, not stdout.
6517
6518 2002-04-09 Akim Demaille <akim@epita.fr>
6519
6520 * src/gram.h, src/gram.c (error_token_number): Remove, use
6521 errtoken->number.
6522 * src/reader.c (reader): Don't specify the user token number (2)
6523 for $undefined, as it uselessly prevents using it.
6524 * src/gram.h (token_number_t): Move to...
6525 * src/symtab.h: here.
6526 (state_t.number): Is a token_number_t.
6527 * src/print.c, src/reader.c: Use undeftoken->number instead of
6528 hard coded 2.
6529 (Even though this 2 is not the same as above: the number of the
6530 undeftoken remains being 2, it is its user token number which
6531 might not be 2).
6532 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
6533 `user_token_number_max'.
6534 Output `undef_token_number'.
6535 * data/bison.simple, data/bison.c++: Use them.
6536 Be sure to map invalid yylex return values to
6537 `undef_token_number'. This saves us from gratuitous SEGV.
6538
6539 * tests/conflicts.at (Solved SR Conflicts)
6540 (Unresolved SR Conflicts): Adjust.
6541 * tests/regression.at (Web2c Actions): Adjust.
6542

6546 Adding #line.
6547 Remove the duplicate `typedefs'.

6549 Use __ofile__.
6550 * data/bison.simple: Use __ofile__.
6551 * src/scan-skel.l: Handle __ofile__.

6554
6555 * src/gram.h (item_number_t): New, the type of item numbers in
6556 RITEM. Note that it must be able to code symbol numbers as
6557 positive number, and the negation of rule numbers as negative
6558 numbers.
6559 Adjust all dependencies (pretty many).
6560 * src/reduce.c (rule): Remove this `short *' pointer: use
6561 item_number_t.
6562 * src/system.h (MINSHORT, MAXSHORT): Remove.
6563 Include `limits.h'.
6564 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
6565 (shortcpy): Remove.

6571 500.
6572 * tests/regression.at (Web2c Actions): Ajust.
6573
6574 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
6575 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
6576 passes, but produces negative #line number, once fixed, GCC is
6577 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
6578 C), it passes.
6579 * src/state.h (state_h): Code input lines on ints, not shorts.
6580
6581 2002-04-08 Akim Demaille <akim@epita.fr>
6582
6583 * src/reduce.c (reduce_grammar): First reduce the nonterminals,

6596 New.
6597 Use them to define yy_token_number_type/TokenNumberType.
6598 Use this type for yytranslate.

6600 253.
6601 * tests/regression.at (Web2c Actions): Adjust.

6677
6678 2002-04-07 Akim Demaille <akim@epita.fr>

6713 (prepare_tokens): this.
6714 In addition to `translate', prepare the muscles `tname' and

6734 * src/closure.c (closure): Now that the initial state has its
6735 items properly set, there is no need for a special case when
6736 creating `ruleset'.
6737
6738 As a result, now the rule 0, reducing to $axiom, is visible in the
6739 outputs. Adjust the test suite.

7078
7079 Remove the support for C++ namespace cleanliness; it was
7080 causing more problems than it was curing, since it didn't work

7128 directives around tables only needed for debugging.
7129
7130 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
7131
7132 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

7157 * data/bison.c++: Adjust to the M4 back end.
7158 More is certainly needed.

7175 action member.
7176 Adjust callers.
7177 (output_skeleton): Don't look for the skeleton location, let m4 do
7178 that.
7179 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
7180 file will be used.
7181 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
7182 (prepare): Given that for the time being changesyntax is not

7185 * src/output.h (actions_output, guards_output)
7186 (token_definitions_output): Adjust prototypes.
7187 * src/scan-skel.l: Instead of scanning the skeletons, it now
7188 processes the output of m4: `__oline__' and `#output'.
7189 * data/bison.simple: Adjust to be used by M4(sugar).
7190 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
7191 to date.
7192 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
7193 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
7194 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
7195 shamelessly stolen from CVS Autoconf.

7203 2002-02-05 Akim Demaille <akim@epita.fr>
7204
7205 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
7206 which have no values.
7207
7208 2002-02-05 Akim Demaille <akim@epita.fr>
7209
7210 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
7211 * data/: here.
7212
7213 2002-01-29 Paul Eggert <eggert@twinsun.com>
7214
7215 * src/bison.simple (YYSIZE_T): Do not define merely because
7216 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
7217 On some platforms, <alloca.h> does not declare YYSTD (size_t).
7218
7219 2002-01-27 Akim Demaille <akim@epita.fr>
7220
7221 Fix `%nonassoc and eof'.
7222
7223 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
7224 which were not properly copied! Replace
7225 memcpy (res->errs, src->errs, src->nerrs);
7226 with
7227 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
7228 !!!
7229 * tests/regression.at (%nonassoc and eof): Adjust to newest
7230 Autotest: `.' is not in the PATH.
7231
7232 2002-01-27 Akim Demaille <akim@epita.fr>
7233
7234 * tests/sets.at (AT_EXTRACT_SETS): New.
7235 (Nullable): Use it.
7236 (Firsts): New.
7237
7238 2002-01-26 Akim Demaille <akim@epita.fr>
7239
7240 * tests/actions.at, tests/calc.at, tests/headers.at,
7241 * tests/torture.at: Adjust to the newest Autotest which no longer
7242 forces `.' in the PATH.
7243
7244 2002-01-25 Akim Demaille <akim@epita.fr>
7245
7246 * tests/regression.at (%nonassoc and eof): New.
7247 Suggested by Robert Anisko.
7248
7249 2002-01-24 Akim Demaille <akim@epita.fr>
7250
7251 Bison dumps core when trying to complain about broken input files.
7252 Reported by Cris van Pelt.
7253
7254 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
7255 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
7256 into...
7257 (Invalid inputs): Strengthen: exercise parse_percent_token.
7258
7259 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
7260
7261 * src/Makefile.am: Add bison.c++.
7262 * src/bison.c++: New skeleton.
7263
7264 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
7265
7266 * po/it.po: New.
7267
7268 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
7269
7270 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
7271
7272 2002-01-20 Marc Autret <marc@gnu.org>
7273
7274 * src/files.c (compute_output_file_names): Fix
7275
7276 2002-01-20 Marc Autret <marc@gnu.org>
7277
7278 * tests/output.at: New test.
7279 * src/files.c (compute_base_names): Don't map extensions when
7280 the YACC flag is set, use defaults.
7281 Reported by Evgeny Stambulchik.
7282
7283 2002-01-20 Marc Autret <marc@gnu.org>
7284
7285 * src/system.h: Need to define __attribute__ away for non-GCC
7286 compilers as well (i.e. the vendor C compiler).
7287 Suggested by Albert Chin-A-Young.
7288
7289 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
7290
7291 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
7292 canonical definition.
7293 * src/system.h: Use the canonical definition for PARAMS (avoids
7294 a conflict with the macro from lib/hash.h).
7295
7296 2002-01-11 Akim Demaille <akim@epita.fr>
7297
7298 * configure.in: Use AC_FUNC_STRNLEN.
7299 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
7300
7301 2002-01-09 Akim Demaille <akim@epita.fr>
7302
7303 * src/files.c, src/files.h (output_infix): New.
7304 (tab_extension): Remove.
7305 (compute_base_names): Compute the former, drop the latter.
7306 * src/output.c (prepare): Insert the muscles `output-infix', and
7307 `output-suffix'.
7308 * src/parse-skel.y (string, string.1): New.
7309 (section.header): Use it.
7310 (section.yacc): Remove.
7311 (prefix): Remove too.
7312 * src/scan-skel.l: Adjust.
7313 * src/bison.simple, src/bison.hairy: Adjust.
7314
7315 2002-01-09 Akim Demaille <akim@epita.fr>
7316
7317 * configure.in (WERROR_CFLAGS): Compute it.
7318 * src/Makefile.am (CFLAGS): Pass it.
7319 * tests/atlocal.in (CFLAGS): Idem.
7320 * src/files.c: Fix a few warnings.
7321 (get_extension_index): Remove, unused.
7322
7323 2002-01-08 Akim Demaille <akim@epita.fr>
7324
7325 * src/getargs.c (AS_FILE_NAME): New.
7326 (getargs): Use it to convert DOSish file names.
7327 * src/files.c (base_name): Rename as full_base_name to avoid
7328 clashes with `base_name ()'.
7329 (filename_split): New.
7330 (compute_base_names): N-th rewrite, using filename_split.
7331
7332 2002-01-08 Akim Demaille <akim@epita.fr>
7333
7334 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
7335 New, stolen from the Fileutils 4.1.
7336 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
7337 * configure.in: Check for the presence of memrchr, and of its
7338 prototype.
7339
7340 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
7341
7342 * lib/hash.h (__P): Added definition for this macro.
7343 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
7344 BUILT_SOURCES, to ensure they are generated first.
7345 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
7346 %error-verbose to allow bootstrapping with bison 1.30x.
7347
7348 2002-01-06 Akim Demaille <akim@epita.fr>
7349
7350 * src/reader.c (parse_braces): Don't fetch the next char, the
7351 convention is to fetch on entry.
7352 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
7353 'switch' without a following semicolon.
7354 * tests/regression.at (braces parsing): New.
7355
7356 2002-01-06 Akim Demaille <akim@epita.fr>
7357
7358 Bison is dead wrong in its RR conflict reports.
7359
7360 * tests/torture.at (GNU Cim Grammar): New.
7361 * src/conflicts.c (count_rr_conflicts): Fix.
7362
7363 2002-01-06 Akim Demaille <akim@epita.fr>
7364
7365 Creating package.m4 from configure.ac causes too many problems.
7366
7367 * tests/Makefile.am (package.m4): Create it by hand,
7368 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
7369
7370 2002-01-06 Akim Demaille <akim@epita.fr>
7371
7372 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
7373 skeleton.h.
7374
7375 2002-01-04 Paul Eggert <eggert@twinsun.com>
7376
7377 * doc/bison.texinfo (Debugging):
7378 Remove YYSTDERR; it's no longer defined or used.
7379 Also, s/cstdio.h/cstdio/.
7380
7381 2002-01-03 Akim Demaille <akim@epita.fr>
7382
7383 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
7384
7385 2002-01-03 Akim Demaille <akim@epita.fr>
7386
7387 * src/parse-skel.y (process_skeleton): Don't bind the parser's
7388 tracing code to --trace, wait for a better --trace option, with
7389 args.
7390
7391 2002-01-03 Akim Demaille <akim@epita.fr>
7392
7393 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
7394 The ISO C++ standard is extremely clear about it: stderr is
7395 considered a macro, not a regular symbol (see table 94 `Header
7396 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
7397 Therefore std:: does not apply to it. It still does with fprintf.
7398 Also, s/cstdio.h/cstdio/.
7399
7400 2002-01-03 Akim Demaille <akim@epita.fr>
7401
7402 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
7403 for non system headers.
7404
7405 2002-01-02 Akim Demaille <akim@epita.fr>
7406
7407 Equip the skeleton chain with location tracking, runtime trace,
7408 pure parser and scanner.
7409
7410 * src/parse-skel.y: Request a pure parser, locations, and prefix
7411 renaming.
7412 (%union): Having several members with the same type does not help
7413 type mismatches, simplify.
7414 (YYPRINT, yyprint): New.
7415 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
7416 (skel_error): this.
7417 Handle locations.
7418 * src/scan-skel.l: Adjust to these changes.
7419 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
7420 (LOCATION_PRINT, skel_control_t): New.
7421
7422 2001-12-30 Akim Demaille <akim@epita.fr>
7423
7424 * src/parse-skel.y: Get rid of the shift/reduce conflict:
7425 replace `gb' with BLANKS.
7426 * src/scan-skel.l: Adjust.
7427
7428 2001-12-30 Akim Demaille <akim@epita.fr>
7429
7430 * src/system.h: We don't need nor want bcopy.
7431 Throw away MS-DOS crap: we don't need getpid.
7432 * configure.in: We don't need strndup. It was even causing
7433 problems: because Flex includes the headers *before* us,
7434 _GNU_SOURCE is not defined by config.h, and therefore strndup was
7435 not visible.
7436 * lib/xstrndup.c: New.
7437 * src/scan-skel.l: Use it.
7438 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
7439 * src/parse-skel.y: Use %directives instead of #defines.
7440
7441 2001-12-30 Akim Demaille <akim@epita.fr>
7442
7443 * src/skeleton.h: New.
7444 * src/output.c (output_parser, output_master_parser): Remove, dead
7445 code.
7446 * src/output.h (get_lines_number, actions_output, guards_output)
7447 (token_definitions_output): Prototype them.
7448 * src/parse-skel.y: Add the license notice.
7449 Include output.h and skeleton.h.
7450 (process_skeleton): Returns void, and takes a single parameter.
7451 * src/scan-skel.l: Add the license notice.
7452 Include skeleton.h.
7453 Don't use %option yylineno: it seems that then Flex imagines
7454 REJECT has been used, and therefore it won't reallocate its
7455 buffers (which makes no other sense to me than a bug). It results
7456 in warnings for `unused: yy_flex_realloc'.
7457
7458 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
7459
7460 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
7461 (MUSCLE_INSERT_PREFIX): ...to there.
7462 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
7463 (MUSCLE_INSERT_PREFIX): Move from here...
7464
7465 * src/bison.hairy: Add a section directive. Put braces around muscle
7466 names. This parser skeleton is still broken, but Bison should not
7467 choke on a bad muscle 'syntax'.
7468 * src/bison.simple: Add a section directive. Put braces around muscle
7469 names.
7470
7471 * src/files.h (strsuffix, stringappend): Add declarations.
7472 (tab_extension): Add declaration.
7473 (short_base_name): Add declaration.
7474
7475 * src/files.c (strsuffix, stringappend): No longer static. These
7476 functions are used in the skeleton parser.
7477 (tab_extension): New.
7478 (compute_base_names): Use the computations done in this function
7479 to guess if the generated parsers should have '.tab' in their
7480 names.
7481 (short_base_name): No longer static.
7482
7483 * src/output.c (output_skeleton): New.
7484 (output): Disable call to output_master_parser, and give a try to
7485 a new skeleton handling system.
7486 (guards_output, actions_output): No longer static.
7487 (token_definitions_output, get_lines_number): No longer static.
7488
7489 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
7490
7491 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
7492 parse-skel.y.
7493
7494 * src/parse-skel.y: New file.
7495 * src/scan-skel.l: New file.
7496
7497 2001-12-29 Akim Demaille <akim@epita.fr>
7498
7499 %name-prefix is broken.
7500
7501 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
7502 Adjust all dependencies.
7503 * tests/headers.at (export YYLTYPE): Strengthen this test: use
7504 %name-prefix.
7505
7506 Renaming yylval but not yylloc is not consistent. Now we do.
7507
7508 * src/bison.simple: Prefix yylloc if used.
7509 * doc/bison.texinfo (Decl Summary): Document that.
7510
7511 2001-12-29 Akim Demaille <akim@epita.fr>
7512
7513 * doc/bison.texinfo: Promote `%long-directive' over
7514 `%long_directive'.
7515 Remove all references to fixed-output-files, yacc is enough.
7516
7517 2001-12-29 Akim Demaille <akim@epita.fr>
7518
7519 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
7520 user prologue. These are defaults.
7521 * tests/actions.at (Mid-rule actions): Make sure the user can
7522 define YYDEBUG and YYERROR_VERBOSE.
7523
7524 2001-12-29 Akim Demaille <akim@epita.fr>
7525
7526 * src/output.c (header_output): Don't forget to export YYLTYPE and
7527 yylloc.
7528 * tests/headers.at (export YYLTYPE): New, make sure it does.
7529 * tests/regression.at (%union and --defines, Invalid CPP headers):
7530 Move to...
7531 * tests/headers.at: here.
7532
7533 2001-12-29 Akim Demaille <akim@epita.fr>
7534
7535 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
7536
7537 2001-12-29 Akim Demaille <akim@epita.fr>
7538
7539 * tests/actions.at (Mid-rule actions): Output on a single line
7540 instead of several.
7541
7542 2001-12-29 Akim Demaille <akim@epita.fr>
7543
7544 * doc/bison.texinfo: Formatting changes.
7545
7546 2001-12-29 Akim Demaille <akim@epita.fr>
7547
7548 Don't store the token defs in a muscle, just be ready to output it
7549 on command. Now possible via `symbols'. Fixes a memory leak.
7550
7551 * src/output.c (token_definitions_output): New.
7552 (output_parser, header_output): Use it.
7553 * src/reader.c (symbols_save): Remove.
7554
7555 2001-12-29 Akim Demaille <akim@epita.fr>
7556
7557 * src/bison.simple: Do not provide a default for YYSTYPE and
7558 YYLTYPE before the user's prologue. Otherwise it's hardly... a
7559 default.
7560
7561 2001-12-29 Akim Demaille <akim@epita.fr>
7562
7563 Mid-rule actions are simply... ignored!
7564
7565 * src/reader.c (readgram): Be sure to attach mid-rule actions to
7566 the empty-rule associated to the dummy symbol, not to the host
7567 rule.
7568 * tests/actions.at (Mid-rule actions): New.
7569
7570 2001-12-29 Akim Demaille <akim@epita.fr>
7571
7572 Memory leak.
7573
7574 * src/reader.c (reader): Free grammar.
7575
7576 2001-12-29 Akim Demaille <akim@epita.fr>
7577
7578 Memory leak.
7579
7580 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
7581 since it allocates it for each state, although only one is needed.
7582 (allocate_storage): Do it here.
7583
7584 2001-12-29 Akim Demaille <akim@epita.fr>
7585
7586 * src/options.h, src/options.c (create_long_option_table): Rename
7587 as...
7588 (long_option_table_new): this, with a clearer prototype.
7589 (percent_table): Remove, unused,
7590 * src/getargs.c (getargs): Adjust.
7591
7592 2001-12-29 Akim Demaille <akim@epita.fr>
7593
7594 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
7595 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
7596 as states.
7597
7598 2001-12-29 Akim Demaille <akim@epita.fr>
7599
7600 * src/lalr.c (build_relations): Rename `states' as `states1'.
7601 Sorry, I don't understand exactly what it is, no better name...
7602
7603 2001-12-29 Akim Demaille <akim@epita.fr>
7604
7605 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
7606 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
7607 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
7608 as rules.
7609
7610 2001-12-29 Akim Demaille <akim@epita.fr>
7611
7612 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
7613 ago.
7614
7615 2001-12-29 Akim Demaille <akim@epita.fr>
7616
7617 * src/reader.c, src/reader.h (user_toknums): Remove.
7618 Adjust all users to use symbols[i]->user_token_number.
7619
7620 2001-12-29 Akim Demaille <akim@epita.fr>
7621
7622 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
7623 Adjust all users to use symbols[i]->prec or ->assoc.
7624
7625 2001-12-29 Akim Demaille <akim@epita.fr>
7626
7627 * src/reader.c, src/reader.h (tags): Remove.
7628 Adjust all users to use symbols[i]->tag.
7629
7630 2001-12-29 Akim Demaille <akim@epita.fr>
7631
7632 * src/gram.h, src/gram.c (symbols): New, similar to state_table
7633 and rule_table.
7634 * src/reader.c (packsymbols): Fill this table.
7635 Drop sprec.
7636 * src/conflicts.c (resolve_sr_conflict): Adjust.
7637 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
7638 single table.
7639 Use symbols[i]->tag instead of tags[i].
7640
7641 2001-12-29 Akim Demaille <akim@epita.fr>
7642
7643 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
7644 In addition, put a comment in there, to replace...
7645 * tests/regression.at (%union and C comments): Remove.
7646
7647 2001-12-29 Akim Demaille <akim@epita.fr>
7648
7649 * tests/regression.at (Web2c Actions): Blindly move the actual
7650 output as expected output. The contents *seem* right to me, but I
7651 can't pretend reading perfectly parser tables... Nonetheless, all
7652 the other tests pass correctly, the table look OK, even though the
7653 presence of `$axiom' is to be noted: AFAICS it is useless (but
7654 harmless).
7655
7656 2001-12-29 Akim Demaille <akim@epita.fr>
7657
7658 * src/reader.c (readgram): Don't add the rule 0 if there were no
7659 rules read. In other words, add it _after_ having performed
7660 grammar sanity checks.
7661 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
7662
7663 2001-12-29 Akim Demaille <akim@epita.fr>
7664
7665 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
7666 visible, and some states have now a different number.
7667
7668 2001-12-29 Akim Demaille <akim@epita.fr>
7669
7670 * src/reader.c (readgram): Bind the initial rule's lineno to that
7671 of the first rule.
7672 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
7673 (Solved SR Conflicts): Adjust rule 0's line number.
7674
7675 2001-12-29 Akim Demaille <akim@epita.fr>
7676
7677 Fix the `GAWK Grammar' failure.
7678
7679 * src/LR0.c (final_state): Initialize to -1 so that we do compute
7680 the reductions of the first state which was mistakenly confused
7681 with the final state because precisely final_state was initialized
7682 to 0.
7683 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
7684 now noticed by Bison.
7685 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
7686 have a reduction on $default.
7687
7688 2001-12-29 Akim Demaille <akim@epita.fr>
7689
7690 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
7691 rule line numbers.
7692 * src/closure.c (print_closure): Likewise.
7693 * src/derives.c (print_derives): Likewise.
7694 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
7695 now.
7696
7697 2001-12-29 Akim Demaille <akim@epita.fr>
7698
7699 * src/lalr.c (lookaheads_print): New.
7700 (lalr): Call it when --trace-flag.
7701 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
7702 are dumped.
7703
7704 2001-12-29 Akim Demaille <akim@epita.fr>
7705
7706 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
7707 when walking through ritem, even via rule->rhs.
7708 * src/reduce.c (dump_grammar, useful_production, reduce_output)
7709 (useful_production, useless_nonterminals): Likewise.
7710 (reduce_grammar_tables): Likewise, plus update nritems.
7711 * src/nullable.c (set_nullable): Likewise.
7712 * src/lalr.c (build_relations): Likewise.
7713 * tests/sets.at (Nullable): Adjust.
7714 Fortunately, now, the $axiom is no longer nullable.
7715
7716 2001-12-29 Akim Demaille <akim@epita.fr>
7717
7718 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
7719 the 0-sentinel.
7720 * src/gram.c (ritem_longest_rhs): Likewise.
7721 * src/reduce.c (nonterminals_reduce): Likewise.
7722 * src/print_graph.c (print_graph): Likewise.
7723 * src/output.c (output_rule_data): Likewise.
7724 * src/nullable.c (set_nullable): Likewise.
7725
7726 2001-12-29 Akim Demaille <akim@epita.fr>
7727
7728 * src/output.c: Comment changes.
7729
7730 2001-12-27 Paul Eggert <eggert@twinsun.com>
7731
7732 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
7733 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
7734 Sparc, as they were causing more porting problems than the
7735 (minor) performance improvement was worth.
7736
7737 Also, catch up with 1.31's YYSTD.
7738
7739 2001-12-27 Akim Demaille <akim@epita.fr>
7740
7741 * src/output.c (output_gram): Rely on nritems, not the
7742 0-sentinel. See below.
7743 Use -1 as separator, not 0.
7744 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
7745 Rely on -1 as separator in yyrhs, instead of 0.
7746 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
7747 twice `Now at end of input', therefore there are two lines less to
7748 expect.
7749
7750 2001-12-27 Akim Demaille <akim@epita.fr>
7751
7752 * tests/regression.at (Unresolved SR Conflicts):
7753 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
7754 below.
7755
7756 2001-12-27 Akim Demaille <akim@epita.fr>
7757
7758 * src/LR0.c (new_state): Recognize the final state by the fact it
7759 is reached by eoftoken.
7760 (insert_start_shifting_state, insert_eof_shifting_state)
7761 (insert_accepting_state, augment_automaton): Remove, since now
7762 these states are automatically computed from the initial state.
7763 (generate_states): Adjust.
7764 * src/print.c: When reporting a rule number to the user, substract
7765 1, so that the axiom rule is rule 0, and the first user rule is 1.
7766 * src/reduce.c: Likewise.
7767 * src/print_graph.c (print_core): For the time being, just as for
7768 the report, depend upon --trace-flags to dump the full set of
7769 items.
7770 * src/reader.c (readgram): Once the grammar read, insert the rule
7771 0: `$axiom: START-SYMBOL $'.
7772 * tests/set.at: Adjust: rule 0 is now displayed, and since the
7773 number of the states has changed (the final state is no longer
7774 necessarily the last), catch up.
7775
7776 2001-12-27 Akim Demaille <akim@epita.fr>
7777
7778 Try to make the use of the eoftoken valid. Given that its value
7779 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
7780 is used instead of > 0 where appropriate, (ii), depend upon nritems
7781 instead of the 0-sentinel.
7782
7783 * src/gram.h, src/gram.c (nritems): New.
7784 Expected to be duplication of nitems, but for the time being...
7785 * src/reader.c (packgram): Assert nritems and nitems are equal.
7786 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
7787 * src/closure.c (print_closure, print_fderives): Likewise.
7788 * src/gram.c (ritem_print): Likewise.
7789 * src/print.c (print_core, print_grammar): Likewise.
7790 * src/print_graph.c: Likewise.
7791
7792 2001-12-27 Akim Demaille <akim@epita.fr>
7793
7794 * src/main.c (main): If there are complains after grammar
7795 reductions, then output the report anyway if requested, then die.
7796 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
7797 * src/reader.c (eoftoken): New.
7798 (parse_token_decl): If the token being defined has value `0', it
7799 is the eoftoken.
7800 (packsymbols): No longer hack `tags' to insert `$' by hand.
7801 Be sure to preserve the value of the eoftoken.
7802 (reader): Make sure eoftoken is defined.
7803 Initialize nsyms to 0: now eoftoken is created just like the others.
7804 * src/print.c (print_grammar): Don't special case the eof token.
7805 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
7806 lie anyway, albeit pleasant.
7807 * tests/calc.at: Exercise error messages with eoftoken.
7808 Change the grammar so that empty input is invalid.
7809 Adjust expectations.
7810 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
7811
7812 2001-12-27 Akim Demaille <akim@epita.fr>
7813
7814 * configure.in: Check the protos of strchr ans strspn.
7815 Replace strchr if needed.
7816 * src/system.h: Provide the protos of strchr, strspn and memchr if
7817 missing.
7818 * lib/strchr.c: New.
7819 * src/reader.c (symbols_save): Use strchr.
7820
7821 2001-12-27 Akim Demaille <akim@epita.fr>
7822
7823 * src/print.c, src/print_graph.c (escape): New.
7824 Use it to quote the TAGS outputs.
7825 * src/print_graph.c (print_state): Now errors are in red, and
7826 reductions in green.
7827 Prefer high to wide: output the state number on a line of its own.
7828
7829 2001-12-27 Akim Demaille <akim@epita.fr>
7830
7831 * src/state.h, src/state.c (reductions_new): New.
7832 * src/LR0.c (set_state_table): Let all the states have a
7833 `reductions', even if reduced to 0.
7834 (save_reductions): Adjust.
7835 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
7836 * src/print.c (print_reductions, print_actions): Adjust.
7837 * src/output.c (action_row): Adjust.
7838
7839 2001-12-27 Akim Demaille <akim@epita.fr>
7840
7841 * src/state.h, src/state.c (errs_new, errs_dup): New.
7842 * src/LR0.c (set_state_table): Let all the states have an errs,
7843 even if reduced to 0.
7844 * src/print.c (print_errs, print_reductions): Adjust.
7845 * src/output.c (output_actions, action_row): Adjust.

7851
7852 2001-12-27 Akim Demaille <akim@epita.fr>
7853
7854 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...

7856 (lookaheadset, shiftset): New, used as additional storage by
7857 print_reductions.

7859 (print_shifts, print_gotos, print_errs): New, extracted from...
7860 (print_actions): here.
7861 * src/print_graph.c (print_actions): Remove dead code.
7862
7863 2001-12-27 Akim Demaille <akim@epita.fr>
7864
7865 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
7866 `$n' and `@n'.
7867
7868 2001-12-27 Akim Demaille <akim@epita.fr>
7869
7870 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
7871 (build_relations): Adjust.
7872
7873 2001-12-27 Akim Demaille <akim@epita.fr>
7874
7875 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
7876 duplication.
7877
7878 2001-12-27 Akim Demaille <akim@epita.fr>
7879
7880 * src/reader.c (packgram): Catch nitems overflows.
7881
7882 2001-12-27 Akim Demaille <akim@epita.fr>
7883
7884 * src/files.c, src/files.h (guard_obstack): Remove.
7885 * src/output.c (output): Adjust.
7886 * src/reader.c (parse_braces): New, factoring...
7887 (copy_action, copy_guard): these two which are renamed as...
7888 (parse_action, parse_guard): these.
7889 As a voluntary consequence, using braces around guards is now
7890 mandatory.
7891
7892 2001-12-27 Akim Demaille <akim@epita.fr>
7893
7894 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
7895 * src/reader.c (symbol_list): `guard' and `guard_line' are new
7896 members.
7897 (symbol_list_new): Adjust.
7898 (copy_action): action_line is the first line, not the last.
7899 (copy_guard): Just as for actions, store the `action' only, not
7900 the switch/case/break flesh.
7901 Don't parse the user action that might follow the guard, let...
7902 (readgram): do it, i.e., now, there can be an action after a
7903 guard.
7904 In other words the guard is just explicitly optional.
7905 (packgram): Adjust.
7906 * src/output.c (guards_output): New.
7907 (output_parser): Call it when needed.
7908 (output): Also free the guard and attrs obstacks.
7909 * src/files.c, src/files.h (obstack_save): Remove.
7910 (output_files): Remove.
7911 As a result, if one needs the former `.act' file, using an
7912 appropriate skeleton which requires actions and guards is now
7913 required.
7914 * src/main.c (main): Adjust.
7915 * tests/semantic.at: New.
7916 * tests/regression.at: Use `input.y' as input file name.
7917 Avoid 8+3 problems by requiring input.c when the test needs the
7918 parser.
7919
7920 2001-12-27 Akim Demaille <akim@epita.fr>
7921
7922 * src/reader.c (symbol_list_new): Be sure to initialize all the
7923 fields.
7924
7925 2001-12-27 Akim Demaille <akim@epita.fr>
7926
7927 All the hacks using a final pseudo state are now useless.
7928
7929 * src/LR0.c (set_state_table): state_table holds exactly nstates.
7930 * src/lalr.c (nLA): New.
7931 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
7932 instead of lookaheadsp from the pseudo state (nstate + 1).
7933
7934 2001-12-27 Akim Demaille <akim@epita.fr>
7935
7936 * src/output.c (action_row, token_actions): Use a state_t instead
7937 of a integer, and nlookaheads instead of the following state's
7938 lookaheadsp.
7939
7940 2001-12-27 Akim Demaille <akim@epita.fr>
7941
7942 * src/conflicts.c (log_resolution, flush_shift)
7943 (resolve_sr_conflict, set_conflicts, solve_conflicts)
7944 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
7945 (conflicts_print, print_reductions): Use a state_t instead of an
7946 integer when referring to a state.
7947 As much as possible, depend upon nlookaheads, instead of the
7948 `lookaheadsp' member of the following state (since lookaheads of
7949 successive states are successive, the difference between state n + 1
7950 and n served as the number of lookaheads for state n).
7951 * src/lalr.c (add_lookback_edge): Likewise.
7952 * src/print.c (print_core, print_actions, print_state)
7953 (print_results): Likewise.
7954 * src/print_graph.c (print_core, print_actions, print_state)
7955 (print_graph): Likewise.

7958 2001-12-27 Akim Demaille <akim@epita.fr>
7959
7960 * src/bison.hairy: Formatting/comment changes.
7961 ANSIfy.
7962 Remove `register' indications.
7963 Add plenty of `static'.
7964
7965 2001-12-27 Akim Demaille <akim@epita.fr>
7966
7967 * src/output.c (prepare): Drop the muscle `ntbase' which
7968 duplicates ntokens.
7969 * src/bison.simple: Formatting/comment changes.
7970 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
7971 is an undocumented synonym.
7972
7973 2001-12-22 Akim Demaille <akim@epita.fr>
7974
7975 * src/output.c (output_table_data): Change the prototype to use
7976 `int' for array ranges: some invocations do pass an int, not a
7977 short.
7978 Reported by Wayne Green.
7979
7980 2001-12-22 Akim Demaille <akim@epita.fr>
7981
7982 Some actions of web2c.y are improperly triggered.
7983 Reported by Mike Castle.
7984
7985 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
7986 * tests/regression.at (Web2c): Rename as...
7987 (Web2c Report): this.
7988 (Web2c Actions): New.
7989
7990 2001-12-22 Akim Demaille <akim@epita.fr>
7991
7992 Reductions in web2c.y are improperly reported.
7993 Reported by Mike Castle.

7996 * tests/regression.at (Web2c): New.
7997
7998 2001-12-18 Akim Demaille <akim@epita.fr>
7999
8000 Some host fail on `assert (!"foo")', which expands to
8001 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
8002 Reported by Nelson Beebee.
8003
8004 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
8005 `#define it_succeeded 0' and `assert (it_succeeded)'.
8006
8007 2001-12-17 Marc Autret <autret_m@epita.fr>
8008
8009 * src/bison.simple: Don't hard code the skeleton line and filename.
8010 * src/output.c (output_parser): Rename 'line' as 'output_line'.
8011 New line counter 'skeleton_line' (skeleton-line muscle).
8012
8013 2001-12-17 Paul Eggert <eggert@twinsun.com>
8014
8015 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
8016 YYDEBUG must be defined to a nonzero value.
8017
8018 * src/bison.simple (yytname): Do not assume that the user defines
8019 YYDEBUG to a properly parenthesized expression.
8020
8021 2001-12-17 Akim Demaille <akim@epita.fr>
8022
8023 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
8024 nlookaheads is a new member.
8025 Adjust all users.
8026 * src/lalr.h (nlookaheads): Remove this orphan declaration.
8027 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
8028 state.
8029
8030 2001-12-17 Akim Demaille <akim@epita.fr>
8031
8032 * src/files.h, src/files.c (open_files, close_files): Remove.
8033 * src/main.c (main): Don't open/close files, nor invoke lex_free,
8034 let...

8048
8049 * src/output.c (output_obstack): Be static and rename as...
8050 (format_obstack): this, to avoid any confusion with files.c's
8051 output_obstack.
8052 * src/reader.h (muscle_obstack): Move to...
8053 * src/output.h: here, since it's defined in output.c.
8054
8055 2001-12-17 Akim Demaille <akim@epita.fr>
8056
8057 * src/output.c (action_row, save_column, default_goto)
8058 (sort_actions, matching_state, pack_vector): Better variable
8059 locality.
8060
8061 2001-12-17 Akim Demaille <akim@epita.fr>
8062
8063 * src/output.c: Various formatting changes.
8064
8065 2001-12-17 Akim Demaille <akim@epita.fr>
8066
8067 * src/files.c (output_files): Free the output_obstack.
8068 * src/main.c (main): Call print and print_graph conditionally.
8069 * src/print.c (print): Work unconditionally.
8070 * src/print_graph.c (print_graph): Work unconditionally.
8071 * src/conflicts.c (log_resolution): Output only if verbose_flag.
8072
8073 2001-12-16 Marc Autret <autret_m@epita.fr>
8074
8075 * src/output.c (actions_output): Fix. When we use %no-lines,
8076 there is one less line per action.
8077
8078 2001-12-16 Marc Autret <autret_m@epita.fr>
8079
8080 * src/bison.simple: Remove a useless #line directive.
8081 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
8082 * src/output.c (get_lines_number): New.
8083 (output_parser): Adjust, now takes care about the lines of a
8084 output muscles.
8085 Fix line numbering.
8086 (actions_output): Computes the number of lines taken by actions.
8087 (output_master_parser): Insert new skeleton which is the name of
8088 the output parser file name.
8089
8090 2001-12-15 Marc Autret <autret_m@epita.fr>

8099
8100 Make `make distcheck' work.
8101
8102 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
8103 system.h which uses libgettext.h.
8104
8105 2001-12-15 Akim Demaille <akim@epita.fr>
8106
8107 * src/nullable.c (set_nullable): Useless rules must be skipped,
8108 otherwise, since we range over their symbols, we might look at a
8109 nonterminal which no longer ``exists'', i.e., it is not counted in
8110 `nvars', hence we overflow our arrays.
8111
8112 2001-12-15 Akim Demaille <akim@epita.fr>
8113
8114 The header can also be produced directly, without any obstack!
8115 Yahoo!
8116
8117 * src/files.c, src/files.h (defines_obstack): Remove.
8118 (compute_header_macro): Global.
8119 (defines_obstack_save): Remove.
8120 * src/reader.c (parse_union_decl): No longer output to
8121 defines_obstack: its content can be found in the `stype' muscle
8122 anyway.
8123 (output_token_translations): Merge into...
8124 (symbols_output): this.
8125 Rename as...
8126 (symbols_save): this.
8127 (reader): Adjust.
8128 * src/output.c (header_output): New.
8129 (output): Call it.
8130
8131 2001-12-15 Akim Demaille <akim@epita.fr>
8132
8133 * src/reader.c (parse_union_decl): Instead of handling two obstack
8134 simultaneously, use one to define the `stype' muscle, and use the
8135 value of the latter to fill defines_obstack.
8136 (copy_comment): Remove.
8137 (copy_comment2): Work for a single obstack.
8138 Rename as...
8139 (copy_comment): this.
8140
8141 2001-12-15 Akim Demaille <akim@epita.fr>
8142
8143 * src/lex.c, src/lex.h (xgetc): No longer static.
8144 * src/reader.c (parse_union_decl): Revamp.
8145
8146 2001-12-15 Akim Demaille <akim@epita.fr>
8147
8148 Still making progress in separating Bison into (i) input, (ii)
8149 process, (iii) output: now we can directly output the parser file
8150 without using table_obstack at all.
8151
8152 * src/files.c, src/files.h (table_obstack): Bye bye.
8153 (parser_file_name): New.
8154 * src/files.c (compute_output_file_names): Compute it.
8155 * src/output.c (actions_output, output_parser)
8156 (output_master_parser): To a file instead of an obstack.
8157
8158 2001-12-15 Akim Demaille <akim@epita.fr>
8159
8160 Attach actions to rules, instead of pre-outputting them to
8161 actions_obstack.
8162
8163 * src/gram.h (rule_t): action and action_line are new members.
8164 * src/reader.c (symbol_list): Likewise.
8165 (copy_action): Save the actions within the rule.
8166 (packgram): Save them in rule_table.
8167 * src/output.c (actions_output): New.
8168 (output_parser): Use it on `%%actions'.
8169 (output_rule_data): Don't free rule_table.
8170 (output): Do it.
8171 (prepare): Don't save the `action' muscle.
8172 * src/bison.simple: s/%%action/%%actions/.
8173
8174 2001-12-15 Akim Demaille <akim@epita.fr>
8175
8176 * src/reader.c (copy_action): When --yacc, don't append a `;'
8177 to the user action: let it fail if lacking.
8178 Suggested by Arnold Robbins and Tom Tromey.
8179
8180 2001-12-14 Akim Demaille <akim@epita.fr>
8181
8182 * src/lex.c (literalchar): Simply return the char you decoded, non
8183 longer mess around with obstacks and int pointers.
8184 Adjust all callers.
8185
8186 2001-12-14 Akim Demaille <akim@epita.fr>
8187
8188 * src/lex.c (literalchar): Don't escape the special characters,
8189 just decode them, and keep them as char (before, eol was output as
8190 the 2 char string `\n' etc.).
8191 * src/output.c (output_rule_data): Use quotearg to output the
8192 token strings.
8193
8194 2001-12-13 Paul Eggert <eggert@twinsun.com>
8195
8196 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
8197 Do not infringe on the global user namespace when using C++.
8198 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
8199 All uses of `fprintf' and `stderr' changed.
8200
8201 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
8202
8203 2001-12-13 Akim Demaille <akim@epita.fr>
8204
8205 The computation of nullable is broken: it doesn't handle empty
8206 RHS's properly.
8207
8208 * tests/torture.at (GNU AWK Grammar): New.
8209 * tests/sets.at (Nullable): New.
8210 * src/nullable.c (set_nullable): Instead of blindly looping over
8211 `ritems', loop over the rules, and then over their rhs's.
8212
8213 Work around Autotest bugs.
8214
8215 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
8216 frame, because Autotest understand lines starting with a `+' as
8217 traces from the shell. Then, they are not processed properly.
8218 Admittedly an Autotest bug, but we don't have time to wait for
8219 Autotest to catch up.
8220 * tests/regression.at (Broken Closure): Adjust to the new table
8221 frames.
8222 Move to...
8223 * tests/sets.at: here.
8224
8225 2001-12-13 Akim Demaille <akim@epita.fr>
8226
8227 * src/closure.c (closure): Use nrules instead of playing tricks
8228 with BITS_PER_WORD.
8229
8230 2001-12-13 Akim Demaille <akim@epita.fr>
8231
8232 * src/print.c (print_actions): Output the handling of `$' as the
8233 traces do: shifting the token EOF. Before EOF was treated as a
8234 nonterminal.
8235 * tests/regression.at: Adjust some tests.
8236 * src/print_graph.c (print_core): Complete the set of items via
8237 closure. The next-to-final and final states are still unsatisfying,
8238 but that's to be addressed elsewhere.
8239 No longer output the rule numbers, but do output the state number.
8240 A single loop for the shifts + gotos is enough, but picked a
8241 distinct color for each.
8242 (print_graph): Initialize and finalize closure.
8243
8244 2001-12-13 Akim Demaille <akim@epita.fr>
8245
8246 * src/reader.c (readgram): Remove dead code, an strip useless
8247 braces.
8248 (get_type): Remove, unused.
8249
8250 2001-12-12 Akim Demaille <akim@epita.fr>
8251
8252 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
8253 on that of lib/error.c.
8254
8255 2001-12-12 Akim Demaille <akim@epita.fr>
8256
8257 Some hosts don't like `/' in includes.
8258
8259 * src/system.h: Include libgettext.h without qualifying the path.
8260 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
8261 $(top_srcdir).
8262
8263 2001-12-11 Marc Autret <autret_m@epita.fr>
8264
8265 * src/output.c (output_parser): Remove useless muscle.
8266
8267 2001-12-11 Marc Autret <autret_m@epita.fr>
8268
8269 * src/bison.simple: Remove #line just before %%epilogue. It
8270 is now handled in ...
8271 * src/reader.c (read_additionnal_code): Add the output of a
8272 #line for the epilogue.
8273
8274 2001-12-10 Marc Autret <autret_m@epita.fr>
8275
8276 * src/reader.c (copy_definition): Re-use CPP-outed code which
8277 replace precedent remove.
8278 * src/bison.simple: Remove #line before %%prologue because
8279 %%input-line is wrong at this time.
8280
8281 2001-12-10 Marc Autret <autret_m@epita.fr>
8282
8283 * src/reader.c (symbols_output): Clean up.
8284 * src/output.c (output_gram, output): Clean up.
8285
8286 2001-12-10 Akim Demaille <akim@epita.fr>
8287
8288 * src/lalr.c (initialize_lookaheads): New. Extracted from...
8289 * src/LR0.c (set_state_table): here.
8290 * src/lalr.c (lalr): Call it.
8291
8292 2001-12-10 Akim Demaille <akim@epita.fr>
8293
8294 * src/state.h (shifts): Remove the `number' member: shifts are
8295 attached to state, hence no longer need to be labelled with a
8296 state number.
8297
8298 2001-12-10 Akim Demaille <akim@epita.fr>
8299
8300 Now that states have a complete set of members, the linked list of
8301 shifts is useless: just fill directly the state's shifts member.
8302
8303 * src/state.h (shifts): Remove the `next' member.
8304 * src/LR0.c (first_state, last_state): Remove.
8305 Adjust the callers.
8306 (augment_automaton): Don't look for the shifts that must be added
8307 a shift on EOF: it is those of the state we looked for! But now,
8308 since shifts are attached, it is no longer needed to looking
8309 merely by its id: its number.
8310
8311 2001-12-10 Akim Demaille <akim@epita.fr>
8312
8313 * src/LR0.c (augment_automaton): Better variable locality.
8314 Remove an impossible branch: if there is a state corresponding to
8315 the start symbol being shifted, then there is shift for the start
8316 symbol from the initial state.
8317
8318 2001-12-10 Akim Demaille <akim@epita.fr>
8319
8320 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
8321 only when appropriate: when insert_start_shifting_state' is not
8322 invoked.
8323 * tests/regression.at (Rule Line Numbers): Adjust.
8324
8325 2001-12-10 Akim Demaille <akim@epita.fr>
8326
8327 * src/LR0.c (augment_automaton): Now that all states have shifts,
8328 merge the two cases addition shifts to the initial state.
8329
8330 2001-12-10 Akim Demaille <akim@epita.fr>
8331
8332 * src/lalr.c (set_state_table): Move to...
8333 * src/LR0.c: here.
8334 * src/lalr.c (lalr): Don't call it...
8335 * src/LR0.c (generate_states): do it.
8336 * src/LR0.h (first_state): Remove, only the table is used.
8337
8338 2001-12-10 Akim Demaille <akim@epita.fr>
8339
8340 * src/LR0.h (first_shift, first_reduction): Remove.
8341 * src/lalr.c: Don't use first_shift: find shifts through the
8342 states.
8343
8344 2001-12-10 Akim Demaille <akim@epita.fr>
8345
8346 * src/LR0.c: Attach shifts to states as soon as they are
8347 computed.
8348 * src/lalr.c (set_state_table): Instead of assigning shifts to
8349 state, just assert that the mapping was properly done.
8350
8351 2001-12-10 Akim Demaille <akim@epita.fr>
8352
8353 * src/LR0.c (insert_start_shift): Rename as...
8354 (insert_start_shifting_state): this.
8355 (insert_eof_shifting_state, insert_accepting_state): New.
8356 (augment_automaton): Adjust.
8357 Better locality of the variables.
8358 When looking if the start_symbol is shifted from the initial
8359 state, using `while (... symbol != start_symbol ...)' sounds
8360 better than `while (... symbol < start_symbol ...)': If fail
8361 to see how the order between symbols could be relevant!
8362
8363 2001-12-10 Akim Demaille <akim@epita.fr>
8364
8365 * src/getargs.h: Don't declare `spec_name_prefix' and
8366 `spec_file_prefix', declared by src/files.h.
8367 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
8368 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
8369 * src/output.c (prepare): Adjust.
8370 * src/reader.c (symbols_output): Likewise.
8371 * src/vmsgetargs.c: Vaguely adjust, but who cares?
8372
8373 2001-12-10 Akim Demaille <akim@epita.fr>
8374
8375 * src/muscle_tab.c (muscle_init): NULL is a better default than
8376 `"0"'.
8377
8378 2001-12-10 Akim Demaille <akim@epita.fr>
8379
8380 * src/reader.c (reader): Calling symbols_output once is enough.
8381
8382 2001-12-10 Akim Demaille <akim@epita.fr>
8383
8384 Now that states have a complete set of members, the linked list of
8385 reductions is useless: just fill directly the state's reductions
8386 member.
8387
8388 * src/state.h (struct reductions): Remove member `number' and
8389 `next'.
8390 * src/LR0.c (first_reduction, last_reduction): Remove.
8391 (save_reductions): Don't link the new reductions, store them in
8392 this_state.
8393 * src/lalr.c (set_state_table): No need to attach reductions to
8394 states, it's already done.
8395 * src/output.c (output_actions): No longer free the shifts, then
8396 the reductions, then the states: free all the states and their
8397 members.
8398
8399 2001-12-10 Akim Demaille <akim@epita.fr>
8400
8401 * src/options.c (OPTN, DRTV, BOTH): New.
8402 (option_table): Use them.
8403
8404 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
8405 the job of system.h.
8406 * src/options.c: Don't include stdio.h and xalloc.h for the same
8407 reasons.
8408
8409 2001-12-10 Akim Demaille <akim@epita.fr>
8410
8411 * src/output.c (output, prepare): Make sure the values of the
8412 muscles `action' and `prologue' are 0-terminated.
8413
8414 2001-12-10 Akim Demaille <akim@epita.fr>
8415
8416 Clean up GCC warnings.
8417
8418 * src/reader.c (copy_action): `buf' is not used.
8419 (parse_skel_decl): Be static.
8420 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
8421 * src/options.h (create_long_option_table): Have a real prototype.
8422 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
8423 (hash_delete_at): Return const void *.
8424 Adjust casts to preserve the const.
8425
8426 2001-12-10 Akim Demaille <akim@epita.fr>
8427
8428 * configure.in: Require 2.52g.
8429 M4 is not needed, but AUTOM4TE is.
8430 * m4/m4.m4: Remove.
8431 * tests/Makefile.am: Adjust.
8432
8433 2001-12-10 Akim Demaille <akim@epita.fr>
8434
8435 One structure for states is enough, even though theoretically
8436 there are LR(0) states and LALR(1) states.
8437
8438 * src/lalr.h (state_t): Remove.
8439 (state_table): Be state_t **, not state_t *.
8440 * src/state.h (core, CORE_ALLOC): Rename as...
8441 (state_t, STATE_ALLOC): this.
8442 Add the LALR(1) members: shifts, reductions, errs.
8443 * src/LR0.c (state_table): Rename as...
8444 (state_hash): this, to avoid name clashes with the global
8445 `state_table'.
8446 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
8447 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
8448
8449 2001-12-10 Akim Demaille <akim@epita.fr>
8450
8451 Bison dumps core on bash.y.
8452 Reported by Pascal Bart.
8453
8454 * src/warshall.c (bitmatrix_print): New.
8455 (TC): Use it.
8456 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
8457 j must be the outer loop.
8458 * tests/regression.at (Broken Closure): New.
8459
8460 2001-12-05 Akim Demaille <akim@epita.fr>
8461
8462 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
8463 its argument.
8464 Reported by Peter Hamorsky.
8465
8466 2001-12-05 Akim Demaille <akim@epita.fr>
8467
8468 * src/conflicts.c (err_table): Remove.
8469 (resolve_sr_conflict): Adjust.
8470 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
8471 Rename as...
8472 (state_t.reductions, state_t.shifts): this.
8473
8474 2001-12-05 Akim Demaille <akim@epita.fr>
8475
8476 * src/reduce.c (reduce_grammar_tables): No longer disable the
8477 removal of useless rules via CPP but via `if (0)', so that the
8478 compiler still check the code is valid.
8479 For instance, it should have noticed `rline' no longer exists: use
8480 the `line' member of rule_t.
8481 * src/gram.c (dummy, rline): Remove, unused.
8482
8483 2001-12-05 Akim Demaille <akim@epita.fr>
8484
8485 * src/output.c (pack_vector): Use assert, not berror.
8486 * src/main.c (berror): Remove, unused.
8487
8488 2001-12-05 Akim Demaille <akim@epita.fr>
8489
8490 New experimental feature: if --verbose --trace output all the
8491 items of a state, not only its kernel.
8492
8493 * src/print.c (print_core): If `trace_flag', then invoke closure
8494 before outputting the items of the state (print_core is no longer
8495 a correct name them).
8496 (print_results): Invoke new_closure/free_closure if needed.
8497
8498 2001-12-05 Akim Demaille <akim@epita.fr>
8499
8500 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
8501 * src/closure.c, src/closure.h (itemsetsize): Rename as...
8502 (nitemset): for consistency with the rest of the project.
8503
8504 2001-12-05 Akim Demaille <akim@epita.fr>
8505
8506 * src/closure.c (print_closure): Improve.
8507 (closure): Use it for printing input and output.
8508
8509 2001-12-05 Akim Demaille <akim@epita.fr>
8510
8511 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
8512 indexed by nonterminals.
8513
8514 2001-12-05 Akim Demaille <akim@epita.fr>
8515
8516 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
8517 what it was!).
8518 * src/warshall.h: Remove accidental duplication of the content.
8519
8520 2001-12-05 Akim Demaille <akim@epita.fr>
8521
8522 * src/closure.c (set_fderives): De-obfuscate.
8523
8524 2001-12-05 Akim Demaille <akim@epita.fr>
8525
8526 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
8527
8528 2001-12-05 Akim Demaille <akim@epita.fr>
8529
8530 * src/closure.c (set_firsts): De-obfuscate.
8531
8532 2001-12-05 Akim Demaille <akim@epita.fr>
8533
8534 * src/output.c (action_row): De-obfuscate
8535 using the good o' techniques: arrays not pointers, variable
8536 locality, BITISSET, RESETBIT etc.
8537
8538 2001-12-05 Akim Demaille <akim@epita.fr>
8539
8540 Pessimize the code to simplify it: from now on, all the states
8541 have a valid SHIFTS, which NSHIFTS is possibly 0.
8542
8543 * src/LR0.c (shifts_new): Be global and move to..
8544 * src/state.c, src/state.h: here.
8545 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
8546 * src/print_graph: Adjust.
8547
8548 2001-12-05 Akim Demaille <akim@epita.fr>
8549
8550 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
8551 * src/conflicts.c: Use it.
8552 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
8553 incorrectly ``simplified''.
8554
8555 2001-12-05 Akim Demaille <akim@epita.fr>
8556
8557 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
8558 using the good o' techniques: arrays not pointers, variable
8559 locality, BITISSET, RESETBIT etc.
8560

8564 * src/conflicts.c: Use it to deobfuscate.
8565
8566 2001-12-05 Akim Demaille <akim@epita.fr>
8567
8568 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
8569 (print_reductions): De-obfuscate using the good o' techniques:
8570 arrays not pointers, variable locality, BITISSET.
8571
8572 2001-12-05 Akim Demaille <akim@epita.fr>
8573
8574 * src/conflicts.c (print_reductions): Arrays, not pointers.

8596 * src/lalr.c: Use them.
8597
8598 2001-12-05 Akim Demaille <akim@epita.fr>
8599

8602
8603 2001-12-05 Akim Demaille <akim@epita.fr>
8604
8605 * src/lalr.c (matrix_print): New.
8606 (transpose): Use it.
8607 Use arrays instead of pointers.
8608
8609 2001-12-05 Akim Demaille <akim@epita.fr>
8610
8611 * src/lalr.c (maxrhs): Move to...
8612 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
8613 * src/lalr.c (build_relations): Adjust.
8614
8615 2001-12-05 Akim Demaille <akim@epita.fr>
8616
8617 * src/lalr.c (transpose): Free the memory allocated to the
8618 argument, as it is replaced by the results by the unique caller.
8619 (build_relations): Merely invoke transpose: it handles the memory
8620 deallocation.
8621 Improve variable locality.
8622 Avoid variables used as mere abbreviations.
8623 (compute_lookaheads): Use arrays instead of pointers.
8624

8638
8639 * src/lalr.c (traverse): Use arrays instead of pointers.
8640
8641 2001-12-05 Akim Demaille <akim@epita.fr>
8642
8643 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
8644 the handling of squeue.
8645 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
8646
8647 2001-12-05 Akim Demaille <akim@epita.fr>
8648
8649 Because useless nonterminals are now kept alive (instead of being
8650 `destroyed'), we now sometimes examine them, and store information
8651 related to them. Hence we need to know their number, and adjust
8652 memory allocations.
8653
8654 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
8655 static.
8656 * src/LR0.c (allocate_itemsets): The memory allocated to
8657 `symbol_count' was used for two different purpose: once to count
8658 the number of occurrences of each symbol, and later reassigned to
8659 `shift_symbol', containing the symbol that can be shifted from a
8660 given state.
8661 Deobfuscate, i.e., allocate, use and free `symbol_count' here
8662 only, and...
8663 (new_itemsets): Allocate `shift_symbol' here.
8664 (allocate_itemsets): symbol_count includes useless nonterminals.
8665 Make room for them.
8666 (free_storage): Use `free', not `XFREE', for pointers that cannot
8667 be null.
8668
8669 2001-12-05 Akim Demaille <akim@epita.fr>
8670
8671 * src/nullable.c (set_nullable): Deobfuscate the handling of
8672 ritem.
8673 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
8674
8675 2001-12-05 Akim Demaille <akim@epita.fr>
8676
8677 * src/gram.c, src/gram.h (ritem_print): New.
8678 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
8679 (This useless function was defined only to work around VMS linkers
8680 that can't handle compilation units with variables only).
8681 * src/reduce.c (dump_grammar): Use it to trace the construction of
8682 ritem.
8683
8684 2001-12-04 Paul Eggert <eggert@twinsun.com>
8685
8686 * src/bison.simple (union yyalloc): Change member names
8687 to be the same as the stack names.
8688 (yyparse): yyptr is now union yyalloc *, not char *.
8689 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
8690 and may generate better code on some machines.
8691 (yystpcpy): Use prototype if __STDC__ is defined, not just
8692 if __cplusplus is defined.
8693
8694 2001-11-30 Akim Demaille <akim@epita.fr>
8695
8696 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
8697 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
8698 Gettext doesn't compile cleanly, and dies with -Werror.
8699 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
8700 Include WARNING_CFLAGS here.
8701 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
8702 before being defined.
8703
8704 2001-11-27 Paul Eggert <eggert@twinsun.com>
8705
8706 * lib/quotearg.h (quotearg_n, quotearg_n_style):
8707 First arg is int, not unsigned.
8708 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
8709 (SIZE_MAX, UINT_MAX): New macros.
8710 (quotearg_n_options): Abort if N is negative.
8711 Avoid overflow check on hosts where size_t is 64 bits and int
8712 is 32 bits, as overflow is impossible there.
8713 Fix off-by-one typo that caused unnecessary reallocation.
8714
8715 2001-11-29 Paul Eggert <eggert@twinsun.com>
8716

8718
8719 * doc/bison.texinfo (Bison Parser): Discuss system headers
8720 and their effect on the user name space.

8722 * src/bison.simple:
8723 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
8724 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
8725 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
8726
8727 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
8728 on user names when possible.
8729
8730 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
8731 Simplify test for whather <alloca.h> exists.
8732
8733 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
8734
8735 (<stdio.h>): Include if YYDEBUG.
8736
8737 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
8738 ! defined (yyoverflow) && ! defined (yymemcpy).
8739
8740 (yymemcpy, yyparse): Rename local variables as needed so that
8741 they all begin with 'yy'.
8742
8743 (yystrlen, yystpcpy): New functions.
8744
8745 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
8746 All uses changed.
8747
8748 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
8749 instead of relying on string.h functions. Use YYSTACK_ALLOC
8750 and YYSTACK_FREE instead of malloc and free.
8751
8752 2001-11-30 Akim Demaille <akim@epita.fr>

8761
8762 2001-11-30 Akim Demaille <akim@epita.fr>
8763
8764 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
8765 if body instead of `;' to pacify GCC's warnings.
8766
8767 2001-11-30 Akim Demaille <akim@epita.fr>
8768
8769 Instead of mapping the LHS of unused rules to -1, keep the LHS
8770 valid, but flag the rules as invalid.
8771
8772 * src/gram.h (rule_t): `useful' is a new member.
8773 * src/print.c (print_grammar): Adjust.
8774 * src/derives.c (set_derives): Likewise.
8775 * src/reader.c (packgram, reduce_output): Likewise.

8778
8779 2001-11-30 Akim Demaille <akim@epita.fr>

8785
8786 2001-11-30 Akim Demaille <akim@epita.fr>
8787
8788 * src/reduce.c (nonterminals_reduce): Instead of throwing away
8789 useless nonterminals, move them at the end of the symbol arrays.
8790 (reduce_output): Adjust.
8791 * tests/reduce.at (Useless Nonterminals): Adjust.
8792
8793 2001-11-30 Akim Demaille <akim@epita.fr>

8800 2001-11-29 Paul Eggert <eggert@twinsun.com>
8801
8802 * src/bison.simple (YYSTACK_REALLOC): Remove.
8803 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
8804 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
8805 New macros.
8806 (union yyalloc): New type.
8807 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
8808 an arbitrary restriction on hosts where size_t is wider than int.
8809
8810 (yyparse): Don't dump core if alloca or malloc fails; instead, report
8811 a parser stack overflow. Allocate just one block of memory for all
8812 three stacks, instead of allocating three blocks; this typically is
8813 faster and reduces fragmentation.
8814
8815 Do not limit the number of items in the stack to a value that fits
8816 in 'int', as this is an arbitrary limit on hosts with 64-bit
8817 size_t and 32-bit int.
8818
8819 2001-11-29 Marc Autret <autret_m@epita.fr>

8845 (parse_include_decl): Remove.

8873
8874 * src/closure.c (closure): Instead of looping over word in array

8878
8879 * src/closure.c (closure): No longer optimize the special case

8883 2001-11-28 Akim Demaille <akim@epita.fr>
8884
8885 * src/closure.c (closure): `r' and `c' are new variables, used to

9249 use abs. path to find config.h.
9250 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

9273 * src/lex.c (parse_percent_token): Replace equal_offset with

10652
10653 * src/lex.h: Rename all the tokens:

10673 instead of returning a token.
10674 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
10675 * src/reader.c (read_declarations): Adjust.
10676 * src/files.c (open_files): Don't call `compute_base_names', don't
10677 compute `attrsfile' since they depend upon data which might be
10678 *in* the input file now.
10679 (output_files): Do it here.
10680 * src/output.c (output_headers): Document the fact that this patch
10681 introduces a guaranteed SEGV for semantic parsers.

10783 2000-12-19 Akim Demaille <akim@epita.fr>
10784
10785 * src/files.c (open_files): Yipee! We no longer need all the code
10786 looking for `/tmp' since we have no tmp file.

10817 * lib/obstack.h: Formatting changes.
10818 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
10819 prevents type checking.
10820 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
10821 cast the value to (void *): assigning a `foo *' to a `void *'
10822 variable is valid.
10823 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
10824 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
10825 append characters.

10870 Qualify it `const'.

10979 the `/' which is suspected to open a comment, instead of being
10980 called after `//' or `/*' was read.
10981 (copy_comment, copy_definition, parse_union_decl, copy_action)
10982 (copy_guard): Adjust.
10983
10984 2000-10-16 Akim Demaille <akim@epita.fr>
10985
10986 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

11013 `bison -v' segfaults.
11014 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
11015

11024 of `buffer'.
11025 From Neil Booth.
11026
11027 2000-10-02 Paul Eggert <eggert@twinsun.com>
11028
11029 * bison.s1 (yyparse): Assign the default value
11030 unconditionally, to avoid a GCC warning and make the parser a
11031 tad smaller.
11032
11033 2000-10-02 Akim Demaille <akim@epita.fr>
11034
11035 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
11036 options.
11037
11038 2000-10-02 Akim Demaille <akim@epita.fr>
11039
11040 * src/derives.c, src/print.c, src/reduce.c: To ease the
11041 translation, move some `\n' out of the translated strings.
11042
11043 2000-10-02 Akim Demaille <akim@epita.fr>
11044
11045 The location tracking mechanism is precious for parse error
11046 messages. Nevertheless, it is enabled only when `@n' is used in
11047 the grammar, which is a different issue (you can use it in error
11048 message, but not in the grammar per se). Therefore, there should
11049 be another means to enable it.
11050
11051 * src/getargs.c (getargs): Support `--locations'.
11052 (usage): Report it.
11053 * src/getargs.h (locationsflag): Export it.
11054 * src/lex.c (percent_table): Support `%locations'.
11055 * src/reader.c (yylsp_needed): Remove this variable, now replaced
11056 with `locationsflag'.
11057 * doc/bison.texinfo: Document `--locations' and `%locations'.
11058 Sort the options.
11059 * tests/calc.m4: Test it.
11060
11061 For regularity of the names, replace each
11062 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
11063 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
11064 In addition replace each `flag' with `_flag'.
11065
11066 2000-10-02 Akim Demaille <akim@epita.fr>
11067
11068 Also test parse error messages, including with YYERROR_VERBOSE.
11069
11070 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
11071 associative).
11072 Use it to check the computations.
11073 Use it to check `nonassoc' is honored.
11074 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
11075 `--yyerror-verbose'.
11076 (_AT_CHECK_CALC): Adjust to this option.
11077 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
11078
11079 2000-10-02 Akim Demaille <akim@epita.fr>
11080
11081 Test also `--verbose', `--defines' and `--name-prefix'. Testing
11082 the latter demonstrates a flaw in the handling of non debugging
11083 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
11084 was used in order to simplify:
11085
11086 #if YYDEBUG
11087 if (yydebug)
11088 {
11089 ...
11090 }
11091 #endif
11092
11093 into
11094
11095 if (yydebug)
11096 {
11097 ...
11098 }
11099
11100 unfortunately this leads to a CPP conflict when
11101 `--name-prefix=foo' is used since it produces `#define yydebug
11102 foodebug'.
11103
11104 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
11105 (YYDPRINTF): New macro.
11106 Spread its use.
11107 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
11108 the bison options.
11109 Also test `--verbose', `--defines' and `--name-prefix'.
11110
11111 2000-10-02 Akim Demaille <akim@epita.fr>
11112
11113 Improve the readability of the produced parsers.
11114
11115 * src/bison.s1: Formatting changes.
11116 Improve the comment related to the `$' mark.
11117 (yydefault): Don't fall through to `yyresume': `goto' there.
11118 * src/output.c (output_parser): When the `$' is met, skip the end
11119 of its line.
11120 New variable, `number_of_dollar_signs', to check there's exactly
11121 one `$' in the parser skeleton.
11122
11123 2000-10-02 Akim Demaille <akim@epita.fr>
11124
11125 * lib/xstrdup.c: New file, from the fileutils.
11126 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
11127 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
11128 instead of strlen + xmalloc + strcpy.
11129 * src/symtab.c (copys): Remove, use xstrdup instead.
11130
11131 2000-10-02 Akim Demaille <akim@epita.fr>
11132
11133 * src/gram.h (associativity): New enum type which replaces the
11134 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
11135 `right_assoc', `left_assoc' and `non_assoc'.
11136 Adjust all dependencies.
11137 * src/reader.c: Formatting changes.
11138 (LTYPESTR): Don't define it, use it as a literal in
11139 `reader_output_yylsp'.
11140 * src/symtab.h (symbol_class): New enum type which replaces the
11141 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
11142 `sunknown', `stoken and `snterm'.
11143
11144 2000-10-02 Akim Demaille <akim@epita.fr>
11145
11146 * src/getargs.c (fixed_outfiles): Rename as...
11147 (yaccflag): for consistency and accuracy.
11148 Adjust dependencies.
11149
11150 2000-10-02 Akim Demaille <akim@epita.fr>
11151
11152 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
11153 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
11154 difficult and introduced a lot of core dump. It turns out that
11155 Bison used an implementation of `xmalloc' based on `calloc', and
11156 at various places it does depend upon the initialization to 0. I
11157 have not tried to isolate the pertinent places, and all the former
11158 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
11159 someone should address this issue.
11160
11161 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
11162 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

11173
11174 2000-10-02 Akim Demaille <akim@epita.fr>
11175
11176 * src/state.h (nstates, final_state, first_state, first_shift)
11177 (first_reduction): Move their exportation from here...
11178 * src/LR0.h: to here.
11179 Adjust dependencies.

11236 prototypes.
11237 * src/reader.c: Formatting changes, topological sort,
11238 s/register//.
11239
11240 2000-10-02 Akim Demaille <akim@epita.fr>
11241

11255
11256 * src/output.c (token_actions): Introduce a temporary array,
11257 YYDEFACT, that makes it possible for this function to use
11258 output_short_table.
11259
11260 2000-10-02 Akim Demaille <akim@epita.fr>
11261
11262 `user_toknums' is output as a `short[]' in `output.c', while it is
11263 defined as a `int[]' in `reader.c'. For consistency with the

11268 table.

11310 purpose of config.h. system.h must not try to fix wrong
11311 definitions in config.h.
11312
11313 2000-09-20 Akim Demaille <akim@epita.fr>
11314

11528
11529 Change the handling of @s so that they behave exactly like $s.
11530 There is now a pseudo variable @$ (readble and writable), location
11531 of the lhs of the rule (by default ranging from the location of
11532 the first symbol of the rhs, to the location of the last symbol,
11533 or, if the rhs is empty, YYLLOC).

11568 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

11610 * m4/Makefile.am (EXTRA_DIST): New variable.

12242 New function.
12243 (readgram): Use `#if 0' around code that accepted %command
12244 inside grammar rules: The documentation doesn't allow it,
12245 and it will fail since the %command processors scan for the next %.
12246 (parse_token_decl): Extended the %token
12247 declaration to allow a multi-character symbol as an alias.
12248 (parse_thong_decl): New function.
12249 (read_declarations): Added %thong declarations.

12258 Changed `fatal' to `warnxxx' to avoid aborting for error.
12259 Revised and use multiple warnxxx functions to avoid using VARARGS1.
12260 (read_declarations): Improve the error message for
12261 an invalid character. Do not abort.
12262 (read_declarations, copy_guard, copy_action): Use
12263 printable_version to avoid unprintable characters in printed output.
12264 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
12265 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

12270 (output_headers, output_trailers, output, output_gram)
12271 (output_rule_data): Implement noparserflag variable.

12280
12281 * src/lex.h:
12282 Added THONG and NOOP for alias processing.
12283 Added SETOPT for the new code that allows setting options with %flags.
12284
12285 * src/lex.c:
12286 Include getopt.h. Add some extern decls.
12287 (safegetc): New function to deal with EOF gracefully.
12288 (literalchar); new function to deal with reading \ escapes.
12289 (lex): Use literalchar.
12290 (lex): Implemented "..." tokens.
12291 (literalchar, lex, parse_percent_token): Made tokenbuffer
12292 always contain the token. This includes growing the token
12293 buffer while reading an integer.
12294 (parse_percent_token): Replaced if-else statement with percent_table.
12295 (parse_percent_token): Added % declarations as another
12296 way to specify the flags -n, -l, and -r. Also added hooks for
12297 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
12298 major changes to files.c.
12299 (lex) Retain in the incoming stream a character following
12300 an incorrect '/'.
12301 (skip_white_space, lex): Revised most error messages
12302 and changed fatal to warn to avoid aborting.
12303 (percent_table): Added %thong declarations.
