3 * doc/bison.texinfo (Mid-Rule Actions): Explain how to bury a
4 mid-rule action inside a nonterminal symbol in order to declare a
5 destructor for its semantic value.

10 YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
11 __cplusplus && ! defined _STDLIB_H && !
12 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
13 defined free))]: Include <stdlib.h> rather than rolling our own
14 declarations of malloc and free, to avoid problems with
15 incompatible declarations (using 'throw') C++'s stdlib.h. This
16 should fix Debian bug 340012
17 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
18 reported by Guillaume Melquiond.

22 * NEWS: Clarify symbols versus types in unused-value warnings.
23
24 * configure.ac (AC_INIT): Bump version number.
25
26 2006-02-13 Paul Eggert <eggert@cs.ucla.edu>
27
28 * NEWS: Version 2.1a.
29 * tests/headers.at (AT_TEST_CPP_GUARD_H): Declare yyerror and yylex,
30 since C99 requires this.
31
32 2006-02-11 Paul Eggert <eggert@cs.ucla.edu>
33
34 * m4/c-working.m4: New file.
35 * configure.ac (BISON_TEST_FOR_WORKING_C_COMPILER): Use it.
36
37 2006-02-10 Paul Eggert <eggert@cs.ucla.edu>

39 * Makefile.maint: Merge from coreutils.

43 More portability fixes for problems summarized by Nelson H. F. Beebe.
44
45 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
46 configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
47 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
48 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
49 messes up because C++ code is compiled in 32-bit mode but linked
50 in 64-bit mode.
51
52 2006-02-08 Paul Eggert <eggert@cs.ucla.edu>
53
54 More portability fixes for problems summarized by Nelson H. F. Beebe.
55
56 * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
57 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
58
59 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
60 nodist_PROGRAMS, since we don't need to actually compile the
61 example if we're just doing a plain 'make'. This avoids bothering
62 the installer unnecessarily about problems due to weird C++
63 compilers.
64
65 2006-02-06 Paul Eggert <eggert@cs.ucla.edu>
66
67 More portability fixes for problems summarized by Nelson H. F. Beebe.
68
69 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
70 than #include "...", and compile with -I'.'. The old method was
71 not portable, according to Posix and the C standard, and it does
72 not work with Sun C 5.7, where previous #line directives affect
73 the working directory used in later #include "..." directives.

80
81 More portability fixes for problems summarized by Nelson H. F. Beebe.
82
83 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check that
84 '#include <map>' works and that you can apply ++ to iterators.
85
86 2006-02-01 Paul Eggert <eggert@cs.ucla.edu>
87
88 Work around portability problems summarized by Nelson H. F. Beebe in
89 <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.
90
91 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
92 that '#include <string>' works.
93
94 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
95 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
96 "warning: sorry: semantics of inline function static data `const
97 unsigned char translate_table[262]' are wrong (you'll wind up with
98 multiple copies)".
99
100 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
101 or, xor to not_, and_, or_, and xor_, respectively. This works
102 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
103 random system header somewhere that includes the equivalent of
104 <iso646.h>.
105
106 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
107 -E" works; it apparently doesn't work with PathScale EKO Compiler
108 Suite Version 2.0.
109
110 2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
111
112 During deterministic GLR operation, user actions should be able to
113 influence the parse by changing yychar. To make this easier to fix and
114 to make glr.c easier to evolve in general, don't maintain yytoken in
115 parallel with yychar; just compute yytoken when needed.
116 * tests/glr-regression.at (Incorrect lookahead during deterministic
117 GLR): Check that setting yychar in a user action has the intended
118 effect.
119 * data/glr.c (yyGLRStack): Remove yytokenp member.
120 (yyclearin): Don't set *yytokenp.
121 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
122 yychar rather than *yytokenp to determine the current lookahead.
123 Compute yytoken locally when needed.
124 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
125 point to.
126
127 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
128 after `--report' documentation.
129
130 2006-01-30 Paul Eggert <eggert@cs.ucla.edu>
131
132 * src/parse-gram.y (grammar_declaration): Location of printer
133 symbol is @1, not list->location. Bug reported by twlevo.
134 * tests/input.at (Incompatible Aliases): Adjust to above change.
135
136 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
137
138 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
139 all the test at once. This makes the output easier to read in the
140 normal case.
141
142 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
143 got from <http://bro-ids.org/download.html>. The bug is that
144 when two actions appeared in succession, the second one was
145 scanned before the first one was added to the grammar rule
146 as a midrule action. Bison then output the incorrect warning
147 "parse.y:905.17-906.36: warning: unused value: $3".
148 * src/parse-gram.y (BRACED_CODE, action): These are no longer
149 associated with a value.
150 (rhs): Don't invoke grammar_current_rule_action_append.
151 (action): Invoke it here instead.
152 * src/reader.c (grammar_midrule_action): Now extern.
153 (grammar_current_rule_action_append): Don't invoke
154 grammar_midrule_action; that is now the scanner's job.
155 * src/reader.h (last_string, last_braced_code_loc):
156 (grammar_midrule_action): New decls.
157 * src/scan-gram.l (last_string): Now extern, sigh.
158 (last_braced_code_loc): New extern variable.
159 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
160 rule already has an action.
161 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
162 * tests/input.at (AT_CHECK_UNUSED_VALUES):
163 Add some tests to check that the above changes fixed the bug.
164
165 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
166
167 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
168 All used changed. Check whether the symbol has a destructor,
169 not whether it is typed.
170 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
171 that the values are still reported as unused. All line numbers
172 adjusted.
173
174 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
175
176 Work around a bug in bro 0.8, which underparenthesizes its
177 definition of YYLLOC_DEFAULT.
178 * data/glr.c: Change all uses of YYLLOC_DEFAULT to parenthesize
179 their arguments.
180 * data/lalr1.cc: Likewise.
181 * data/yacc.cc: Likewise.
182
183 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
184
185 Work around a bug in Pike 7.0, and give the Pike folks a
186 better way to override the usual int widths.
187 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
188 user can override the types.
189 (short): #undef, to work around a bug in Pike 7.0.
190 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
191 (union yyalloc.yyss): Use yytype_int16 rather than short.
192 All uses changed.
193 (yysigned_char): Remove.
194 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
195 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
196 * tests/regression.at (Web2c Actions): Adjust to above changes.
197
198 * src/reader.c (check_and_convert_grammar): New function.
199 (reader): Close the input file even if something went wrong during
200 parsing. Minor file descriptor leak reported by twlevo.
201
202 * src/assoc.c (assoc_to_string): Use a default: abort (); case
203 to pacify gcc -Wswitch-default.
204 * src/scan-gram.l (adjust_location): Use a default: break; case
205 to pacify gcc -Wswitch-default.
206 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
207 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
208 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
209 Move these decls to scan-skel.l, since they don't need to be
210 visible elsewhere.
211 * src/scan-skel.l: Accept the above decls.
212 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
213 is used.
214
215 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
216
217 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
218 since we don't want to insist on a version number at the start
219 of the changelog every time.
220 * Makefile.maint: Sync from coreutils a bit better.
221 (sc_trailing_blank): Renamed from sc_trailing_space.
222 All uses changed.
223 (sc_no_if_have_config_h, sc_require_config_h):
224 (sc_prohibit_assert_without_use): New rules.
225 (sc_obsolete_symbols): Don't catch Makefile.maint itself.
226 (sc_dd_max_sym_length): Fix leading spaces in rule.
227 (sc_system_h_headers): Prefix with @.
228 (sc_useless_cpp_parens, m4-check): Output line numbers.
229 (changelog-check): Allow version only in head.
230 * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
231 satisfy new Makefile.maint rule.
232 * data/glr.c: Likewise.
233 * data/glr.cc: Likewise.
234 * data/lalr1.cc: Likewise.

252 * lib/subpipe.h: Likewise.
253 * lib/timevar.c: Likewise.
254 * lib/timevar.h: Likewise.

266 * lib/vbitset.c: Likewise.
267 * tests/local.at: Likewise.
268 * src/scan-gram.l: Don't include verify.h, since system.h does
269 that for us.
270 * .x-sc_require_config_h: New file.
271 * .x-sc_unmarked_diagnostics: New file.
272
273 2006-01-20 Paul Eggert <eggert@cs.ucla.edu>
274
275 Be a bit more systematic about using 'abort'.
276 * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
277 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
278 Put 'default: abort ();' before some other case, to satisfy older
279 pedantic compilers.
280 * lib/bitset_stats.c (bitset_stats_init): Likewise.
281 * lib/ebitset.c (ebitset_elt_find, ebitset_op3_cmp): Likewise.
282 * lib/lbitset.c (lbitset_elt_find, lbitset_op3_cmp): Likewise.

286 (get_arrow_mode_str, get_crossing_type_str, get_view_str):
287 (get_linestyle_str, get_arrowstyle_str): Likewise.
288 * src/conflicts.c (resolve_sr_conflict):
289 Use a default case rather than one for the one remaining enum
290 value, to catch invalid enum values as well.
291 * src/lalr.c (set_goto_map, map_goto):
292 Prefer "assert (FOO);" to "if (!FOO) abort ();".
293 * src/nullable.c (nullable_compute, token_definitions_output):
294 Likewise.
295 * src/reader.c (packgram, reader): Likewise.
296 * src/state.c (transitions_to, state_new, state_reduction_find):
297 Likewise.
298 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias):
299 (symbol_pack): Likewise.
300 * src/tables.c (conflict_row, pack_vector): Likewise.
301 * src/scan-skel.l (QPUTS): Remove unnecessary parens.
302 (BASE_QPUTS, "@output ".*\n): Remove unnecessary asserts.
303 * src/system.h: Don't include <assert.h>.
304 (assert): New macro.
305
306 * doc/bison.texinfo (Prologue, Rules, Actions, Union Decl, Action Decl):

309
310 2006-01-19 Paul Eggert <eggert@cs.ucla.edu>
311
312 Fix some porting glitches found by Nelson H. F. Beebe.
313 * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
314 compilers that don't understand that abort () does not return.
315 * src/state.c (transitions_to): Likewise.
316 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
317 that '#include <cstdlib>' works.
318 * src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
319 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
320 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
321 for the benefit of some pre-C99 compilers.
322
323 * bootstrap: Undo changes to gnulib files that autoreconf made.
324
325 Minor fixups to get 'make maintainer-check' to work.
326 * configure.ac: Don't use -Wnested-externs, as it's incompatible
327 with the new verify.h implementation.
328 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
329 * data/glr.c (YYUSE): Depend on __GNUC__ as well.
330 * data/yacc.c (YYUSE): Likewise.
331 * data/lalr1.cc (yysyntax_error_): YYUSE (yystate).
332 * lib/subpipe.c (end_of_output_subpipe): The args are unused.
333 * src/parse-gram.y (declaration): Don't pass a string constant
334 to a function that expects char *, since GCC might complain
335 about the constant value.
336 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
337 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
338 before #defining them.
339 * tests/glr-regression.at
340 (Incorrectly initialized location for empty right-hand side in GLR):
341 In yyerror, use the msg arg.
342 (Corrupted semantic options if user action cuts parse):
343 (Incorrect lookahead during deterministic GLR):
344 (Incorrect lookahead during nondeterministic GLR):
345 Don't name a local var 'index'; it shadows string.h's 'index'.
346
347 2006-01-19 Akim Demaille <akim@epita.fr>
348
349 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
350 location, not just parts of it.
351

353
354 * NEWS: Document the fact that multiple %unions are now allowed.
355 * doc/bison.texinfo (Union Decl): Likewise.
356 * TODO: This feature is now implemented, so remove it from
357 the wishlist.
358
359 * Makefile.maint: Merge with coreutils Makefile.maint.
360 (CVS_LIST): Use build-aux version if available.
361 (VERSION_REGEXP): New macro.
362 (syntax-check-rules): Add sc_no_if_have_config_h,
363 sc_prohibit_assert_without_use, sc_require_config_h,
364 sc_useless_cpp_parens.
365 (sc_obsolete_symbols): Check for O_NDELAY.
366 (sc_dd_max_sym_length): Track coreutils.
367 (sc_unmarked_diagnostics): Look in all files, not just *.c.
368 (sc_useless_cpp_parens): New rule.
369 (news-date-check): Look for version or today's date.
370 (changelog-check): Don't require version number near head.
371 (copyright-check): Use current year instead of hardwiring 2005.
372 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
373 (announcement): Add --gpg-key-ID.
374
375 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
376 with "file system".
377
378 Avoid undefined behavior that addressed just before the start of an
379 array. Problem reported by twlevo.
380 * src/reader.c (packgram): Prepend a new sentinel before ritem.
381 * src/lalr.c (build_relations): Rely on new sentinel.
382 * src/gram.c (gram_free): Adjust to new sentinel.
383
384 2006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
385
386 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
387 yylookaheadNeeds. All uses updated.
388 (yysplitStack): Rename local yynewLookaheadStatuses to
389 yynewLookaheadNeeds.
390 * data/glr-regression.at (Incorrect lookahead during nondeterministic
391 GLR): In comments, change `lookahead status' to `lookahead need'.
392
393 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
394
395 * data/glr.c (yysplitStack): A little stylistic rewrite.
396
397 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
398
399 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
400
401 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
402
403 * doc/bison.texinfo: Fix some typos.
404 (GLR Semantic Actions): New subsection discussing special
405 considerations because GLR semantic actions might be deferred.
406 (Actions): Mention look-ahead usage of yylval.
407 (Actions and Locations): Mention look-ahead usage of yylloc.
408 (Special Features for Use in Actions): Add YYEOF entry and mention it
409 in the yychar entry.
410 In the yychar entry, remove mention of the local yychar case (pure
411 parser) since this is irrelevant information when writing semantic
412 actions and since it's already discussed in `Bison Symbols' where
413 yychar is otherwise described as an external variable.
414 In the yychar entry, don't call it the `current' look-ahead since it
415 isn't when semantic actions are deferred.
416 In the yychar and yyclearin entries, add note about deferred semantic
417 actions.
418 Add yylloc and yylval entries discussing look-ahead usage.
419 (Look-Ahead Tokens): When discussing yychar, don't call it the
420 `current' look-ahead, and do mention yylval and yylloc.
421 (Error Recovery): Cross-reference `Action Features' when mentioning
422 yyclearin.
423 (Bison Symbols): In the yychar entry, don't call it the `current'
424 look-ahead.
425 In the yylloc and yylval entries, mention look-ahead usage.
426
427 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
428
429 * tests/glr-regression.at: Update copyright year to 2006.
430
431 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
432
433 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
434 use during nondeterministic operation to track which stacks have
435 actually needed the current lookahead.
436 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
437 Allocate, deallocate, resize, and otherwise shuffle space for
438 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
439 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
440 appropriately during nondeterministic operation.
441 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
442 members to store the current lookahead to be used by the deferred
443 user action.
444 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
445 from which the RHS is taken. Set the lookahead members of the new
446 yySemanticOption according to the lookahead status for stack yyk.
447 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
448 yyaddDeferredAction.
449 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
450 members of yySemanticOption before invoking yyuserAction, and then set
451 them back to their current values afterward.
452 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
453 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
454 * tests/glr-regression.at: Remove `.' from the ends of recent test case
455 titles for consistency.
456 (Leaked merged semantic value if user action cuts parse): In order to
457 suppress lint warnings, use arguments in merge function, and assign
458 char value < 128 in main.
459 (Incorrect lookahead during deterministic GLR): New test case.
460 (Incorrect lookahead during nondeterministic GLR): New test case.
461
462 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
463
464 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
465 !yyvaluep as signal that no semantic value is available to print.
466 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
467 to print a semantic value.
468
469 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
470
471 * tests/glr-regression.at: For consistency with my newer test cases,
472 don't thank myself.
473
474 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
475
476 * data/glr.c (yyresolveValue): When merging semantic options, if at
477 least one user action succeeds but a later one cuts the parse, then
478 destroy the semantic value before returning rather than leaking it.
479 (yyresolveStates): If a user action cuts the parse and thus
480 yyresolveValue fails, ignore the (unset) semantic value rather than
481 corrupting the yyGLRState, and empty the semantic options list since
482 the user actions should have called all necessary destructors.
483 Simplify code with YYCHK.
484 * tests/glr-regression.at (Corrupted semantic options if user action
485 cuts parse): New test case.
486 (Undesirable destructors if user action cuts parse): New test case.
487 Before applying any of this patch, this test case never actually failed
488 for me... but only because the corrupted semantic options usually
489 masked this bug.
490 (Leaked merged semantic value if user action cuts parse): New test
491 case.
492
493 2006-01-05 Akim Demaille <akim@epita.fr>
494
495 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

531 --yacc does.
532 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
533 about declarations in the grammar when in Yacc mode, as POSIX does

536 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
537
538 Warn about dubious constructions like "%token T T".
539 Reported by twlevo.

541 * src/symtab.c (symbol_new): Initialize it to false.
542 (symbol_class_set): New arg DECLARING, specifying whether
543 this is a declaration that we want to warn about, if there
544 is more than one of them. All uses changed.
545
546 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
547 Allow multiple %union directives, whose contents concatenate.
548 * src/parse-gram.y (grammar_declaration): Likewise.
549 Use muscle_code_grow, so that we don't need stype_line any more.
550 All uses changed.
551
552 * src/muscle_tab.c (muscle_grow): Fix comment.
553
554 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:

556 Update copyright year to 2006.
557
558 2006-01-03 Akim Demaille <akim@epita.fr>
559
560 Have glr.cc pass (some of) the calc.at tests.
561 * data/glr.cc (b4_parse_param_orig): New.
562 (b4_parse_param): Improve its definition, and bound it more
563 clearly in the skeleton.
564 (b4_epilogue): Append, instead of prepending, in order to keep
565 #line consistency.
566 Simplify the generation of auxiliary functions: locations and
567 purity are mandated.
568 (b4_global_tokens_and_yystype): Honor it.
569 * data/location.cc (c++.m4): Don't include it.
570 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
571 and AT_SKEL_CC_IF.
572 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
573 AT_LALR1_CC_IF.

576 mandated anyway.
577 (AT_CHECK_CALC_GLR_CC): New.
578 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
579
580 2006-01-02 Akim Demaille <akim@epita.fr>
581
582 * src/output.c (output_skeleton): Don't hard wire the inclusion of
583 c.m4.
584 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.

592 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
593 since it's a member. Rename type to isNterm for clarity.
594
595 2005-12-29 Akim <akim@sulaco.local>
596
597 Let glr.cc catch up with symbol_value_print.
598 * data/glr.cc (b4_yysymprint_generate): Replace by...
599 (b4_yy_symbol_print_generate): this.
600 (yy_symbol_print, yy_symbol_value_print): Declare them.
601
602 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
603
604 * src/location.h (boundary): Note that a line or column equal
605 to INT_MAX indicates an overflow.
606 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
607 (rule_length_overflow, increment_rule_length, add_column_width):
608 New functions.
609 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
610 (<SC_BRACED_CODE>"}"):
611 Use increment_rule_length rather than incrementing it by hand.
612 (adjust_location, handle_syncline): Diagnose overflow.
613 (handle_action_dollar, handle_action_at):
614 Fix bug with monstrosities like $-2147483648.
615 Remove now-unnecessary checks.
616 (scan_integer): Verify assumptions and remove now-unnecessary checks.
617 (convert_ucn_to_byte): Verify assumptions.
618 (handle_syncline): New arg LOC. All callers changed.
619 Don't store through a value derived from char const * pointer.
620
621 * src/reader.c (grammar_rule_check): Rewrite slightly to avoid
622 GCC warnings.
623
624 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
625
626 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
627 Remove unnecessary forward static decls.
628
629 2005-12-27 Akim Demaille <akim@epita.fr>
630
631 * src/reader.c (grammar_current_rule_check): Also check that $$
632 is used.

636 Rename as...
637 (grammar_rule_begin, grammar_rule_end): these, for consistency.
638 (grammar_midrule_action, grammar_symbol_append): Now static.
639 * tests/torture.at (input): Don't rely on the default action
640 being always performed.
641 * tests/calc.at: "Set" $$ even when the action is "cut" with
642 YYERROR or other.
643 * tests/actions.at (Exotic Dollars): Instead of using unused
644 values, check that the warning is issued.
645
646 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
647
648 * NEWS: Improve wording for unused-value warnings.
649
650 2005-12-22 Akim Demaille <akim@epita.fr>
651
652 * data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4
653 (b4_yysymprint_generate): Rename as...
654 (b4_yy_symbol_print_generate): this.
655 Generate yy_symbol_print instead of yysymprint.
656 Generate also yy_symbol_value_print, and use it.
657

672 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
673 * tests/actions.at (Exotic Dollars): Use unused values.
674 * tests/calc.at: Likewise.
675 * tests/glr-regression.at (No users destructors if stack 0 deleted):
676 Likewise.

679 rule_useful_p.
680
681 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
682
683 Undo 2005-12-01 tentative license wording change. The wording is
684 still being reviewed by the lawyers, and we don't want to wait for
685 them before publishing a test release. For now, revert to the
686 previous wording.
687 * NEWS: Undo 2005-12-01 change.
688 * data/glr.c: Revert to previous license wording.
689 * data/glr.cc: Likewise.
690 * data/lalr1.cc: Likewise.
691 * data/location.cc: Likewise.
692 * data/yacc.c: Likewise.
693
694 * NEWS: Reword %destructor vs YYABORT etc.
695 * data/glr.c: Use American spacing, for consistency.
696 * data/glr.cc: Likewise.
697 * data/lalr1.cc: Likewise.
698 * data/yacc.c: Likewise.
699 * data/yacc.c: Reformat comments slightly.
700 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
701 for consistency. Fix some spelling errors and reword recently-included
702 text slightly.
703 * tests/cxx-type.at: Cast results of malloc, for C++.
704
705 2005-12-21 Joel E. Denny <address@hidden>
706
707 * tests/cxx-type.at: Construct a tree, count the parents of shared
708 nodes, and free each node once and only once. Previously, the memory
709 for semantic values was leaked instead.
710
711 2005-12-21 Joel E. Denny <address@hidden>
712
713 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
714 (yylval, yylloc): If pure, #define to yystackp->yyval and
715 yystackp->yyloc similar to yychar and yynerrs.
716 (yyparse): If pure, remove local yylval and yylloc. Add local
717 yystackp to accommodate pure definitions of yylval and yylloc.
718 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
719 yylvalp and yyllocp to &yylval and &yylloc.
720 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
721 namespace. Previously, nerrs and char were missing, but lval and lloc
722 weren't necessary.
723 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
724 yylvalp and yyllocp parameters since, if pure, these are now always
725 accessible through yystackp. If not pure, they are still accessible
726 globally.
727 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
728 `if (YYID (N))' to pacify lint.
729
730 2005-12-21 Akim Demaille <akim@epita.fr>
731
732 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
733 destroy the RHS symbols of a rule.
734 * data/yacc.c (yylen): Initialize to 0.
735 Keep its value to the number of items to possibly shift.
736 In particular, a regular successful parse that ends on YYFINAL by
737 a (internal) YYACCEPT must not have yylen != 0.
738 (yyerrorlab, yyreturn): Pop the RHS.
739 Reorder a bit to emphasize the `shifting' bits of code.
740 (YYPOPSTACK): Now accept a number of items to pop.
741 * data/lalr1.cc: Likewise.
742 * data/glr.c: Formatting changes.
743 Use goto instead of fall through.
744 * doc/bison.texinfo (Destructor Decl): Complete.

749 * djgpp/Makefile.maint: Fix PACKAGE variable computation.
750 * djgpp/config.bat: Replace every occurence of the file name
751 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
752 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
753 * djgpp/config.sed: Replace every occurence of the file name
754 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
755 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
756 * djgpp/djunpack.bat: DJGPP specific file.
757 * djgpp/fnchange.lst: DJGPP specific file.
758 * djgpp/README.in: Add new information about how to unpack the bison
759 source on MSDOS and other systems which have 8.3 file name restrictions
760 using djunpack.bat and fnchange.lst.
761
762 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>

768 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
769
770 * data/glr.c: Reorder typedef declarations for structs to match order
771 of struct declarations.
772 Rename yystack everywhere to yystackp except in yyparse where it's not
773 a pointer.
774 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
775 consistency.
776 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
777 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
778 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
779 lint.
780
781 2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
782
783 * tests/sets.at (Accept): Fix typos in regular expression used to
784 sed out the final state number.
785
786 Work around portability problem on Solaris 10: flex-generated
787 files include <stdio.h> before <config.h>, which messes up
788 because the latter defines __EXTENSIONS__. Address the problem
789 by creating two new little files that include <config.h> first,
790 then include the flex-generated files. Rewrite everyone else
791 to include <config.h> first, as well.
792 * lib/timevar.c: Always include "config.h".
793 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

827 (current_lhs, current_lhs_location): Now static.
828 (current_assoc): Remove unused variable.
829
830 Cleanups so that Bison-generated parsers have less lint.
831 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
832 Prepend /*ARGSUSED*/, for lint's sake.
833 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
834 definition if 'lint' is defined.
835 (YYID): New macro (or function, if lint).
836 All uses of /*CONSTCOND*/0 replaced by YYID(0).
837 * data/yacc.c: Likewise.
838 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
839 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
840 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
841 is C++ only.
842 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
843 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
844 Use YYID(0) rather than 0, for lint.
845 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
846 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
847

855
856 * data/glr.c (yyprocessOneStack, yyparse): Synchronize the shift for
857 all stacks.
858 (yyparse): Iterate another stack in order to call user destructors.
859 * tests/glr-regression.at (No users destructors if stack 0 deleted):
860 New test case.
861 (Duplicated user destructor for lookahead): This test now is expected
862 to succeed.
863
864 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
865
866 * NEWS: Document the following change.
867 * data/yacc.c: Say "parser skeleton" rather than "file", since
868 it's no longer just a file.
869 * data/glr.c: Grant a special exception for C GLR parsers, that
870 reads like the already-existing exception for C LALR(1) parsers.
871 * data/glr.cc: Likewise.
872 * data/lalr1.cc: Likewise.
873 * data/location.cc: Likewise.
874 * data/yacc.c: Reword the "written by" statement to clarify that
875 it was the parser skeleton, not the entire output file.
876 * data/glr.c: Written by Paul Hilfinger.
877 * data/glr.cc: Written by Akim Demaille.
878 * data/lalr1.cc: Likewise.

881
882 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
883 Fix typos in previous change that broke 'make check'.

885 supported in C.
886 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
887 Don't check NUM-STDERR-LINES, since the output format is fluctuating.

922 from 1 to N, while values and location start at 0.
923 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
924
925 2005-11-14 Akim Demaille <akim@epita.fr>

999
1000 2005-11-03 Akim Demaille <akim@epita.fr>
1001

1025
1026 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
1027
1028 * bootstrap (cleanup_gnulib): New function. Use it to clean up
1029 gnulib when interrupted. This fixes some race conditions and
1030 works around some portability problems (one noted by Paul
1031 Hilfinger).
1032
1033 2005-10-22 Akim <akim@epita.fr>
1034
1035 * Makefile.cfg: Adjust to config -> build-aux.

1062
1063 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
1064 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
1065
1066 2005-10-13 Akim Demaille <akim@epita.fr>
1067

1074
1075 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
1076
1077 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
1078 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
1079 Problem reported by John P. Hartmann.
1080 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
1081 already defined it.
1082

1105
1106 * examples/calc++/test: Be quiet unless VERBOSE.

1130
1131 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
1132
1133 Undo the parts of the unlocked-I/O change that substituted
1134 putc or puts for printf. This might hurt performance a bit,
1135 but some people prefer the printf style.
1136 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
1137 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

1158 unused-variable warnings.
1159
1160 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

1163
1164 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
1165
1166 Use unlocked I/O for a minor performance improvement on hosts like
1167 GNU/Linux and Solaris that support unlocked I/O. The basic idea
1168 is to use the gnlib unlocked-io module, and to prefer putc and
1169 puts to printf when either will work (since the latter doesn't
1170 come in an unlocked flavor).
1171 * bootstrap (gnulib_modules): Add unlocked-io.
1172 * data/c.m4 (yysymprint): Prefer puts and putc to printf.

1177 * lib/bitset.c (bitset_print): Likewise.
1178 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

1185 * src/output.c (escaped_output): Likewise.
1186 (user_actions_output): Coalesce two printfs.

1239 for posix systems.
1240
1241 * lib/subpipe.h: New function end_of_output_subpipe() added
1242 to allow support for non-posix systems. This is a no-op function
1243 for posix systems.
1244
1245 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
1246 handle the lack of pipe/fork functionality on non-posix systems.

1269 filename type is defined by the user.
1270 Forward declation location and position before the pre-prologue.

1272 (yyresult): this, it's a local variable, not an attribute.
1273 * data/Makefile.am (dist_pkgdata_DATA): Adjust.

1320 * bootstrap (gnulib_modules): Add verify.
1321 * lib/.cvsignore: Add verify.h.
1322 * src/getargs.c: Use ARGMATCH_VERIFY rather than verify.
1323 * src/system.h (verify): Remove.
1324 Include verify.h instead.
1325 * src/tables.c (tables_generate): Use new API for 'verify'.
1326
1327 2005-09-21 Paul Eggert <eggert@cs.ucla.edu>
1328
1329 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use
1330 local variables whose names begin with 'yy'.
1331 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
1332 Trivial changes from Joel E. Denny.
1333
1334 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
1335 it itself.
1336 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
1337 don't use alloca any more.
1338
1339 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
1340 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
1341 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
1342 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
1343 to match yacc.c, to test more hosts.
1344
1345 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
1346
1347 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
1348 doesn't affect behavior.
1349 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
1350 Solaris, AIX, MSC.
1351 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
1352 This works a bit better with glibc, if user code has already included
1353 stdlib.h.
1354 * doc/bison.texinfo (Bison Parser): Document that users can't
1355 arbitrarily use malloc and free for other purposes. Document
1356 that <alloca.h> and <malloc.h> might be included.
1357 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
1358 user must declare alloca.
1359
1360 * HACKING (release): Forwarn the Translation Project about
1361 stable releses.
1362
1363 2005-09-20 Akim Demaille <akim@epita.fr>
1364
1365 * data/glr.c: Use b4_token_enums, not b4_token_enums_defines.
1366
1367 2005-09-19 Paul Eggert <eggert@cs.ucla.edu>
1368
1369 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
1370 (YYSTACK_ALLOC_MAXIMUM): Use it.
1371 (yysyntax_error): New function.
1372 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
1373 multiple syntax errors are reported, and alloca is being used.
1374 Instead, reallocate buffers twice as big each time, so that
1375 we waste at most half the allocated memory. Start with a small
1376 (128-byte) buffer that will suffice in most cases anyway.
1377 Use yysyntax_error to do most of the work.
1378
1379 * doc/bison.texinfo (Error Reporting, Table of Symbols):
1380 yynerrs is the number of errors reported, not the number of
1381 errors encountered.
1382
1383 * tests/glr-regression.at (Duplicated user destructor for lookahead):
1384 Mark it as expected to fail.
1385 Cast result of malloc; problem reported by twlevo@xs4all.nl.
1386 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
1387 Don't start user-code symbols with "yy", to avoid name space problems.
1388
1389 2005-09-19 Akim Demaille <akim@epita.fr>
1390
1391 Remove the traits, failed experiment.
1392 It never proved useful, and anyway because of the current
1393 definition, it was not possible to have several specialization of
1394 this traits, making it useless.
1395 * data/lalr1.cc (yy:traits): Remove.
1396 Inline its definitions in the parser class.
1397
1398 2005-09-19 Akim Demaille <akim@epita.fr>
1399
1400 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
1401 least Mac OSX with a /usr/local install of gettext.
1402
1403 2005-09-19 Akim Demaille <akim@epita.fr>
1404
1405 * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar
1406 and yytoken for similarity with the other skeletons.
1407
1408 2005-09-19 Akim Demaille <akim@epita.fr>
1409
1410 * NEWS, configure.ac: update version number to 2.1a.
1411
1412 2005-09-16 Paul Eggert <eggert@cs.ucla.edu>
1413
1414 * NEWS: Version 2.1.
1415
1416 * NEWS: Remove notice of yytname change, since it was never in an
1417 official release.
1418 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
1419 diagnostic.
1420 * src/output.c (prepare): Likewise.
1421 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
1422 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
1423 is not defined. This is an awful hack, but it's enough for now.
1424 All callers changed.
1425 * tests/glr-regression-at (make_value): Args are const pointers now,
1426 to avoid GCC warning.
1427 (Duplicated user destructor for lookahead): New test. Currently
1428 skipped. It fails on my host but I'm not sure it'll always fail.
1429
1430 2005-09-16 Akim Demaille <akim@epita.fr>
1431
1432 * src/symtab.h (struct symbol): Declare the printer and destructor
1433 as const, to avoid accidental calls to free.
1434 (symbol_destructor_set, symbol_printer_set): Adjust.
1435 * src/symtab.c: Adjust.
1436
1437 2005-09-16 Akim Demaille <akim@epita.fr>
1438
1439 * data/c.m4 (b4_token_enums): New.
1440 (b4_token_defines): Rename as...
1441 (b4_token_enums_defines): this.
1442 (b4_token_defines): New, output only the #defines.
1443 * data/yacc.c, data/glr.c: Adjust.
1444 * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.
1445 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define
1446 as default values.
1447
1448 2005-09-16 Akim Demaille <akim@epita.fr>
1449
1450 * data/lalr1.cc (yylex_): Remove, inline its code.
1451 (yyreport_syntax_error_): Remove, replaced by...
1452 (yysyntax_error_): this which returns a string and leaves to the
1453 caller the call to the users' error function.
1454 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
1455 Move from members of the parser object...
1456 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
1457 to local variables of the parse function.
1458
1459 2005-09-16 Akim Demaille <akim@epita.fr>
1460
1461 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF
1462 since it's in Bison's name space.
1463
1464 2005-09-15 Paul Eggert <eggert@cs.ucla.edu>
1465
1466 * data/glr.c (yyresolveValue): Add default case to pacify
1467 gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl.
1468
1469 * NEWS: Document when yyparse started to return 2.
1470 * doc/bison.texinfo (Parser Function): Document when yyparse
1471 returns 2.
1472
1473 * data/lalr1.cc: Revert part of previous change, as it's incompatible.
1474 (b4_filename_type): Renamed back from b4_file_name_type. All uses
1475 changed.
1476 (class position): file_name -> filename (reverting). All uses changed.
1477
1478 2005-09-14 Paul Eggert <eggert@cs.ucla.edu>
1479
1480 * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't
1481 do anything if $@ exists. This reverts part of the 2005-07-07
1482 patch.
1483
1484 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
1485
1486 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
1487 contains obsolete information and isn't worth distributing as a
1488 separate file anyway.
1489 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
1490 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
1491 All uses of jmp_buf, setjmp, longjmp changed to use these instead.
1492 (yyparse): Abort if user code uses longjmp to throw an unexpected
1493 value.
1494
1495 2005-09-09 Paul Eggert <eggert@cs.ucla.edu>
1496
1497 * data/c.m4 (b4_identification): Define YYBISON_VERSION.
1498 Suggested by twlevo@xs4all.nl.
1499
1500 * data/glr.c (YYCHK1): Do not assume YYE is in range.
1501 This avoids a diagnostic from gcc -Wswitch-enum.
1502 Problem reported by twlevo@xs4all.nl.
1503
1504 * doc/bison.texinfo: Don't use "filename", as per GNU coding
1505 standards. Use "file name" or "file" or "name", depending on
1506 the context.
1507 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
1508 not to hack/foo.tab.c.
1509 (Calc++ Top Level): 2nd arg of main is not const.
1510 * data/glr.c: b4_filename -> b4_file_name.
1511 * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type.
1512 All uses changed.
1513 (class position): filename -> file_name. All uses changed.
1514 * data/yacc.c: b4_filename -> b4_file_name.
1515 * lib/bitset.h: filename -> file_name in local vars.
1516 * lib/bitset_stats.c: Likewise.
1517 * src/files.c: Likewise.
1518 * src/scan-skel.l ("@output ".*\n): Likewise.
1519 * src/files.c (file_name_split): Renamed from filename_split.
1520 * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename.
1521
1522 2005-09-08 Paul Eggert <eggert@cs.ucla.edu>
1523
1524 * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h,
1525 to accommodate latest gnulib.
1526
1527 * tests/glr-regression.at (Duplicate representation of merged trees):
1528 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
1529
1530 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
1531 needed.
1532
1533 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1534
1535 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.
1536 All uses changed. Invoke user destructor after an error during a
1537 split parse (trivial change from Joel E. Denny).
1538
1539 * tests/glr-regression.at
1540 (User destructor after an error during a split parse): New test case.
1541 Problem reported by Joel E. Denny in:
1542 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
1543
1544 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1545
1546 * README-cvs: Give URLs for recommended tools.
1547 Mention Gzip version problem, and bootstrapping issues.
1548 Remove troubleshooting section, as it's somewhat obsolete.
1549
1550 * bootstrap (no_cache): New var, to accommodate different wget
1551 variants. Use it instead of '-C off'. Problem reported by
1552 twlevo@xs4all.nl.
1553
1554 * data/glr.c (yydestroyStackItem): New function.
1555 (yyrecoverSyntaxError, yyreturn): Use it to improve quality of
1556 debugging information. Problem reported by Joel E. Denny.
1557
1558 2005-08-25 Akim Demaille <akim@epita.fr>
1559
1560 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
1561
1562 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
1563

1568 Problem reported by Joel E. Denny in:
1569 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
1570
1571 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>

1573 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
1574 Add strnlen.c.
1575 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
1576 lib-prefix.m4, po.m4.
1577
1578 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
1579 in yydestruct diagnostic, since it might not be an error.
1580 Problem reported by Joel Denny near end of
1581 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1582 * data/lalr1.cc (yyerturn): Likewise.
1583 * data/yacc.c (yyreturn): Likewise.
1584 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
1585
1586 * src/files.c: Remove obsolete FIXME comment.
1587
1588 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
1589 with the other templates, and to fix bogus run-on messages such
1590 as the one reported at the end of
1591 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
1592 All callers changed to avoid the newline.
1593 (yyprocessOneStack): Output two lines rather than one, to accommodate
1594 the above change. This changes the debug output format slightly.
1595
1596 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
1597 reported by Joel E. Denny in
1598 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
1599 (trivial change).
1600 * tests/glr-regression.at (Duplicate representation of merged trees):
1601 New test, from Joel E. Denny in:
1602 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
1603 * THANKS: Add Joel E. Denny.
1604
1605 * configure.ac (AC_INIT): Bump to 2.0c.
1606
1607 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
1608
1609 * NEWS: Version 2.0b.
1610
1611 * Makefile.am (SUBDIRS): Put examples before tests, so that
1612 "make check" doesn't finish with "All 1 tests passed".
1613
1614 * tests/regression.at (Token definitions): Don't rely on
1615 AT_PARSER_CHECK for data that contains backslashes. It currently
1616 uses 'echo', and 'echo' isn't portable if its argument contains
1617 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
1618 that the byte '\0xff' is not printable in the C locale; it is,
1619 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
1620 not printable, so use '\0x81' to test.
1621
1622 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
1623 version of GCC, since the macro is used with non-GCC compilers.
1624
1625 Fix core dump reported by Pablo De Napoli in
1626 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
1627 * tests/regression.at (Invalid inputs with {}): New test.
1628 * src/parse-gram.y (token_name): Translate type before using
1629 it as an index.
1630
1631 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
1632 the user's name space. All uses changed to __attribute__
1633 ((__unused__)).
1634 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
1635 Add __attribute__ ((__noreturn__)).
1636
1637 * etc/clcommit: Remove. We weren't using it, and it failed
1638 "make maintainer-distcheck".
1639 * Makefile.maint: Merge from coreutils.
1640 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
1641 (syntax-check-rules): Change list of rules as described below.
1642 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
1643 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):

1647 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
1648 (sc_space_tab, sc_error_exit_success, sc_changelog):
1649 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
1650 (makefile-check, po-check, author_mark_check):
1651 (makefile_path_separator_check, copyright-check):
1652 Use grep -n, to make it easier to find violations.
1653 Use CVS_LIST and CVS_LIST_EXCEPT.
1654 (header_regexp, h_re): Remove.
1655 (dd_c): New macro.
1656 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
1657 (my-distcheck): Use more-modern GCC flags.
1658 (signatures, %.asc): Remove.
1659 (rel-files, announcement): Remove signatures.
1660 Restore old updating code, even though we don't use it, so
1661 that we're the same as coreutils.
1662 (alpha, beta, major): Depend on news-date-check.
1663 Make the upload commands.
1664
1665 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.

1672 * tests/sets.at: Likewise.
1673
1674 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
1675 we comment out the Autoconf version number.
1676 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
1677 it's error-prone and "make maintainer-distcheck" rejects it.
1678
1679 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
1680 Indent calls to "error" to pacify "make maintainer-distcheck",
1681 when the calls are not intended to be translated.
1682 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
1683
1684 * src/Makefile.am (DEFS): Use +=, to pacify
1685 "make maintainer-distcheck".
1686 (bison_SOURCES): Add scan-skel.h.
1687 (sc_tight_scope): New rule, from coreutils.
1688
1689 * src/files.c (src_extension, header_extension):
1690 Now static, not extern.
1691 * src/getargs.c (short_options): Likewise.
1692 * src/muscle_tab.c (muscle_table): Likewise.
1693 * src/parse-gram.y (current_class, current_type, current_prec):
1694 Likewise.
1695 * src/reader.c (grammar_end, previous_rule_end): Likewise.
1696 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
1697 * src/main.c (main): Cast bindtextdomain and textdomain calls to
1698 void, to avoid warning when NLS is disabled.
1699 * src/output.c: Include scan-skel.h.
1700 (scan_skel): Remove decl, since scan-skel.h does this.
1701 (output_skeleton):
1702 Indent calls to "error" to pacify "make maintainer-distcheck".
1703 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
1704 * src/reader.h (gram_end, gram_lineno): New decls to pacify
1705 "make maintainer-distcheck".
1706 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
1707 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
1708 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
1709 (skel_lex_destroy, scan_skel): Move these decls to...
1710 * src/scan-skel.h: New file.
1711 * src/uniqstr.c (uniqstr_assert):
1712 Indent calls to "error" to pacify "make maintainer-distcheck".
1713
1714 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
1715 not @VAR@.
1716
1717 * tests/torture.at: Revamp to avoid misuse of atoi that
1718 "make maintainer-distcheck" complained about.
1719
1720 * examples/extexi (message): Don't print a message more than once,
1721 and omit line-number decoration that makes Emacs compile think
1722 that informative messages are worth worrying about.
1723
1724 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
1725
1726 * configure.ac: Update version number.
1727
1728 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
1729 accidentally.
1730 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
1731 autogenerated by the maintainer.
1732 * examples/calc++/.cvsignore: Add *.yy.
1733
1734 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
1735 * lib/bitset_stats.c (bitset_stats_init): Likewise.
1736 * lib/bitsetv.c (bitsetv_alloc): Likewise.
1737
1738 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
1739
1740 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
1741 from maintainer-distcheck about casting the argument of 'free'.
1742
1743 * NEWS: Mention recent yytname changes.
1744 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
1745
1746 * bootstrap: For translations that have not yet been upgraded to
1747 the new runtime-po domain, prime the pump by extracting the
1748 relevant strings from the obsolete translations. This code can be
1749 removed once the bison-runtime domain has been translated by each
1750 team.
1751
1752 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
1753 now that token names are already quoted.
1754
1755 Fix problem reported by Anthony Heading.
1756 * data/glr.c (YYTOKEN_TABLE): New macro.
1757 (yytname): Define if YYTOKEN_TABLE.
1758 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
1759 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
1760 (YYERROR_VERBOSE): Define the same way the other skeletons do.
1761 * src/output.c (prepare_symbols): Output token_table_flag.
1762
1763 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
1764
1765 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
1766 again if the first call fails.
1767
1768 * data/glr.c (yytnamerr): New function.
1769 (yyreportSyntaxError): Use it to dequote most string literals.
1770 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
1771 with other skeletons. All uses changed.
1772 (yytnameerr_): New function.
1773 (yyreport_syntax_error): Use it to dequote most string literals.
1774 * data/yacc.c (yytnamerr): New function.
1775 (yyerrlab): Use it to decode most string literals.
1776 * doc/bison.texinfo (Decl Summary, Calling Convention):
1777 Clarify quoting convention of yytname.
1778 * src/output.c (prepare_symbols): Quote all names. This undoes
1779 the 2005-04-17 change, which is now accomplished (mostly) via
1780 changes in the parsers as described above.
1781 * tests/regression.at (Token definitions, Web2c Actions):
1782 Undo most 2005-04-17 change here, too.
1783
1784 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
1785
1786 Fix more problems reported by twlevo@xs4all.nl.
1787 * tests/cxx-type.at: Don't pipe output of ./types through sed to
1788 remove trailing spaces. This loses the exit status of ./types,
1789 and isn't needed since ./types shouldn't be emitting trailing
1790 spaces.
1791 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
1792 as the stack isn't valid in that case.
1793
1794 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
1795 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
1796 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
1797 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
1798 is used.
1799 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
1800 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
1801 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
1802 Likewise.
1803
1804 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
1805 overly-picky compilers that reject 'char *foo = "bar";'.
1806
1807 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
1808 to FILE * parameter, not to stderr. This fixes a typo introduced
1809 in the 2005-07-12 change.
1810
1811 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
1812 warnings from GCC 4.
1813
1814 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
1815 (yyglrShiftDefer, yysplitStack):
1816 Remove unused parameters b4_pure_formals. All uses changed.
1817 (yyglrShift): Remove unused parameters b4_user_formals.
1818 All uses changed.
1819 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
1820
1821 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
1822
1823 Destructor cleanups and regularization among the three skeletons.
1824 * NEWS: Document the behavior changes.
1825 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
1826 stack before failing, as the cleanup code will do it for us now.
1827 * data/lalr1.cc (yyerrlab): Likewise.
1828 * data/glr.c (yyparse): Pop everything off the stack before
1829 freeing it, so that destructors get called properly.
1830 * data/lalr1.cc (yyreturn): Likewise.
1831 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
1832 This is more consistent.
1833 * doc/bison.texinfo (Destructor Decl): Mention more reasons
1834 why destructors might be called. 1.875 -> 2.1.
1835 (Destructor Decl, Decl Summary, Table of Symbols):
1836 Some English-language cleanups for %destructor.
1837 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
1838 Add output line for destructor of start symbol.
1839 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
1840 because of that same extra output line.
1841
1842 * NEWS: Document minor wording changes in diagnostics of
1843 Bison-generated parsers.
1844 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
1845 Remove unused formals. All uses changed.
1846 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
1847 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
1848 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
1849 Rename yyoverflowab to yyexhaustedlab.
1850 When memory exhaustion occurs during syntax-error reporting,
1851 report it separately rather than in a single diagnostic; this
1852 eases translation.
1853 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
1854 (Memory Exhausted): Renamed from Parser Stack Overflow.
1855 Revamp wording slightly to prefer "memory exhaustion".
1856 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
1857
1858 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
1859
1860 Add i18n support to the GLR skeleton. Partially fix the C++
1861 skeleton; a C++ expert needs to finish this. Remove debugging
1862 msgids; there's little point to having them translated, since they
1863 can be understood only by someone who can read the
1864 (English-language) source code.
1865
1866 Generate runtime-po/bison-runtime.pot automatically, so that we
1867 don't have to worry about garbage getting in that file. We'll
1868 make sure after the next official release that old msgids don't
1869 get lost. See
1870 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
1871
1872 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
1873 Now auto-generated.
1874 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
1875 Fix typos in explanations of the runtime file.
1876 * bootstrap: Change gettext keyword from YYI18N to YY_.
1877 Use standard Makefile.in.in in runtime-po, since we'll arrange
1878 for backward-compatible bison-runtime.po files in a different way.
1879 * data/glr.c (YY_): New macro, from yacc.c.
1880 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
1881 Translate messages intended for users.
1882 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
1883 the wording in the other skeletons. We don't know that the memory
1884 is virtual.
1885 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
1886 Use same method that yacc.c uses.
1887 Don't translate debugging messages.
1888 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
1889 it doesn't work (yet), and requires C++ expertise to fix.
1890 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
1891 Move defn to a more logical place, to be consistent with other
1892 skeletons.
1893 Don't translate debugging messages.
1894 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
1895 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
1896 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
1897 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
1898
1899 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
1900 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
1901 void, not int.
1902 * tests/glr-regression.at (Badly Collapsed GLR States):
1903 Likewise.
1904 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
1905 yylex should return 0 at EOF rather than aborting.
1906
1907 Improve tests for stack overflow in GLR parser.
1908 Problem reported by twlevo@xs4all.nl.
1909 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
1910 All uses removed.
1911 (yyStackOverflow): Just longjmp, but with value 2 so that caller
1912 can handle the problem.
1913 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
1914 (yyparse): New local variable yyresult to record the result.
1915 Use result of setjmp to set it, rather than storing itinto
1916 struct.
1917 (yyDone): Remove label.
1918 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
1919 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
1920 if YYABORT is used).
1921 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
1922 yyparse status; put status > 1 into diagnostic.
1923 Check that status==2 works.
1924 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
1925 Use exit status 3 for failure to open (which shouldn't happen).
1926
1927 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
1928
1929 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
1930 1 on syntax error; just let yyparse do its thing.
1931 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
1932 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
1933 (Exploding the Stack Size with Alloca):
1934 (Exploding the Stack Size with Malloc):
1935 Expect exit status 2, not 1, since the parser is supposed to blow
1936 its stack. Problem reported by twlevo@xs4all.nl.
1937
1938 * data/glr.c (yyparse): Don't assume that the initial calls
1939 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
1940 Print a stack-overflow message and fail instead.
1941 Initialize the line-number information before creating the stack,
1942 so that the stack-overflow message can report line zero safely.
1943
1944 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
1945
1946 Fix problems reported by twlevo@xs4all.nl.
1947 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
1948 (yyuserMerge): Provide a default case if b4_mergers is empty.
1949 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
1950 * tests/glr-regression.at
1951 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
1952 Add casts to pacify C++ compilers.
1953 * tests/glr-regression.at (Improper merging of GLR delayed action
1954 sets): Declare yylex before using it.
1955 * tests/Makefile.am (maintainer-check-g++): Fix a stray
1956 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
1957 test for valgrind; valgrind is independent of g++.
1958 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
1959 for compatibility with POSIX 1003.1-2001 (if running coreutils).
1960 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
1961 Use a destructor, so that we can expand the stack. Change
1962 YYSTYPE to char * so that we can free it. Cast result of malloc.
1963
1964 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
1965
1966 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
1967 a valgrind failure. Problem reported by twlevo@xs4all.nl.
1968
1969 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
1970
1971 * PACKAGING: New file, suggested by Bruno Haible and taken from
1972 similar wording in gettext's PACKAGING file.
1973 * NEWS: Mention PACKAGING.
1974 * Makefile.am (EXTRA_DIST): Add PACKAGING.
1975
1976 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
1977
1978 * NEWS: Document recent i18n improvements.
1979 * bootstrap: Get runtime translations into runtime-po.
1980 Create runtime-po files automatically, if possible.
1981 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
1982 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
1983 does not infringe on the user's name space.
1984 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
1985 * doc/bison.texinfo (Internationalization): Revamp the English
1986 and Texinfo syntax a bit, to try to make it clearer.
1987 (Bison Options, Option Cross Key): Mention --print-localedir.
1988 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
1989 YYENABLE_NLS. Quote a bit more.
1990 * runtime-po/.cvsignore: New file.
1991 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
1992 * runtime-po/Rules-quot: Remove; now created by bootstrap.
1993 * runtime-po/quot.sed: Likewise.
1994 * runtime-po/boldquot.sed: Likewise.
1995 * runtime-po/en@quot.header: Likewise.
1996 * runtime-po/en@boldquot.header: Likewise.
1997 * runtime-po/insert-header.sin: Likewise.
1998 * runtime-po/remove-potcdate.sin: Likewise.
1999 * runtime-po/Makevars: Likewise.
2000 * runtime-po/LINGUAS: Likewise.
2001 * runtime-po/de.po: Likewise; we will rely on the translation project
2002 to maintain this, so "bootstrap" should get it.
2003 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
2004 its value.
2005 * src/main.c (main): Bind the bison-runtime domain, too.
2006
2007 2005-07-12 Bruno Haible <bruno@clisp.org>
2008
2009 * data/yacc.c: Include <libintl.h> when NLS is enabled.
2010 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
2011 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
2012 * runtime-po: New directory.
2013 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
2014 $(DOMAIN).pot-update rule, so that old messages are never dropped.
2015 * runtime-po/Rules-quot: New file, copied from po/.
2016 * runtime-po/quot.sed: Likewise.
2017 * runtime-po/boldquot.sed: Likewise.
2018 * runtime-po/en@quot.header: Likewise.
2019 * runtime-po/en@boldquot.header: Likewise.
2020 * runtime-po/insert-header.sin: Likewise.
2021 * runtime-po/remove-potcdate.sin: Likewise.
2022 * runtime-po/Makevars: New file.
2023 * runtime-po/POTFILES.in: New file.
2024 * runtime-po/LINGUAS: New file.
2025 * runtime-po/bison-runtime.pot: New file.
2026 * runtime-po/de.po: New file.
2027 * m4/bison.m4: New file.
2028 * Makefile.am (SUBDIRS): Add runtime-po.
2029 (aclocaldir, aclocal_DATA): New variables.
2030 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
2031 Define aclocaldir.
2032 * src/getargs.c (usage): Document --print-localedir option.
2033 (PRINT_LOCALEDIR_OPTION): New enum item.
2034 (long_options): Add --print-localedir option.
2035 (getargs): Handle --print-localedir option.
2036 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
2037 (Internationalization): New section.
2038
2039 2005-07-12 Akim Demaille <akim@epita.fr>
2040
2041 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
2042 for consistency with the rest of the code.
2043 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
2044 Add separators.
2045
2046 2005-07-12 Akim Demaille <akim@epita.fr>
2047
2048 * src/parse-gram.y: Use %printer instead of YYPRINT.
2049
2050 2005-07-12 Akim Demaille <akim@epita.fr>
2051
2052 * src/symtab.h, src/symtab.c (symbol_print): New.
2053 * src/symlist.h, src/symlist.c (symbol_list_print): New.
2054 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
2055
2056 2005-07-12 Akim Demaille <akim@epita.fr>
2057
2058 * data/glr.c (b4_syncline): Fix (swap) the definitions of
2059 b4_at_dollar and b4_dollar_dollar.
2060
2061 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
2062
2063 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
2064 and Pennello's paper.
2065
2066 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
2067
2068 * data/yacc.c (yyparse): Undo previous patch. Instead,
2069 set yylsp[0] and yyvsp[0] only if the initial action
2070 sets yylloc and yylval, respectively.
2071
2072 * data/yacc.c (yyparse): In the initial action, set
2073 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
2074 This avoids the use of undefined variables if the initial
2075 action does not set yylloc and/or yylval.
2076
2077 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2078
2079 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
2080 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
2081 Remove from CVS. These files are automatically generated.
2082 * examples/extexi: Clarify that this file is now part of Bison,
2083 not GNU M4, and that it works with any POSIX-compatible Awk.
2084 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
2085 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
2086 so that we also get calc++-parser.yy. Geneate it.
2087 Use $(AWK), not gawk, since any conforming Awk will do.
2088 Put comment before action, since older 'make' can't handle comment
2089 in action.
2090 $(BUILT_SOURCES): List all built sources, not just some of them.
2091 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
2092 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
2093 $($(calc_sources_generated)): Remove unnecessary test for existence
2094 of target. (This had a shell syntax error anyway; a stray "x".)
2095 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
2096 calc++-parser.yy.
2097 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
2098
2099 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
2100 implied by the other modules.
2101
2102 2005-07-06 Akim Demaille <akim@epita.fr>
2103
2104 Bind examples/calc++ to the package.
2105 * examples/calc++/Makefile: Remove, replaced by...
2106 * examples/calc++/Makefile.am: ... this new file.
2107 * examples/calc++/test: Remove input.
2108 * examples/calc++/compile: Remove.
2109 * examples/Makefile.am: New.
2110 * configure.ac, Makefile.am: Adjust.
2111 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
2112
2113 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
2114
2115 * data/glr.c (yyFail): Drastically simplify; since the format argument
2116 never had any % directives, we can simply pass it to yyerror.
2117 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
2118 be modified later, as that is the usual style in glr.c.
2119 Problems reported by Paul Hilfinger.
2120
2121 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
2122 and size overflow errors.
2123 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
2124 in case the user prolog sets feature-test macros like _GNU_SOURCE.
2125 (YYSIZEMAX): New macro.
2126 (yystpcpy): New function, taken from yacc.c.
2127 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
2128 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
2129 so that we don't have to maintain their signatures.
2130 (yyFail): Check for buffer overflow, by using vsnprintf rather
2131 than vsprintf. Allocate a bigger buffer if possible.
2132 Report an error if buffer allocation fails.
2133 (yyStackOverflow): New function.
2134 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
2135 the initialization was successful. It might fail if storage was
2136 exhausted.
2137 (yyexpandGLRStack): Add more checks for storage allocation failure.
2138 Use yyStackOverflow to report failures.
2139 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
2140 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
2141 Don't assume stack number fits in int.
2142 (yysplitStack): Check for storage allocation failure.
2143 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
2144 can print diagnostics on storage allocation failure. All callers
2145 changed.
2146 (yyresolveValue): Use yybool for boolean.
2147 (yyreportSyntaxError): Check for size-calculation overflow.
2148 This code is taken from yacc.c.

2184
2185 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
2186 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
2187 which stems from the 2005-05-27 patch.
2188
2189 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2190
2191 * data/glr.c: Modify treatment of unused parameters to permit use
2192 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
2193
2194 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
2195
2196 Fix infringement on user name space reported by Janos Zoltan Szabo.

2204 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2205
2206 Fix infringement on user name space reported by Bruno Haible.
2207 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
2208 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
2209 the user's name space.
2210 (alloca): Include <stdlib.h> to get it, if it's not built in.
2211 (YYMALLOC, YYFREE): Define only if needed.
2212 (malloc, free): Declare, but only if needed, as this infringes on
2213 the user name space.
2214
2215 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2216
2217 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.

2219 with %d format.
2220 * lib/ebitset.c (min, max): Undef before defining.
2221 * lib/vbitset.c (min, max): Likewise.
2222 * lib/subpipe.c (create_subpipe): Save local variables in case
2223 vfork clobbers them.
2224
2225 2005-05-24 Bruno Haible <bruno@clisp.org>
2226
2227 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
2228 error message syntax used by gcc-4.0.
2229
2230 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
2231
2232 * README: Mention m4 1.4.3. Remove obsolete advice about
2233 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
2234
2235 * bootstrap: Remove workaround for problem I encountered with
2236 gettext 0.14.1; it seems to be fixed now.
2237
2238 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
2239
2240 * NEWS: Version 2.0a.
2241
2242 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
2243 the previous change.
2244
2245 Various maintainer cleanups.
2246 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
2247 conftest*, for benefit of CVS commands run at the same time as
2248 "configure". Add build-aux, since "bootstrap" now creates it and
2249 its subfiles.
2250 * Makefile.cfg (move_if_change): Remove.
2251 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
2252 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
2253 (po_repo, do-po-update, po-update, wget_files, get-targets):
2254 (config.guess-url_prefix, config.sub-url_prefix):

2257 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
2258 Remove.
2259 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
2260 this is now the recommended name.
2261 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
2262 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
2263 ylwrap. These files now go into build-aux.
2264 * config/move-if-change: Remove.
2265 * config/prev-version.txt: Bump from 1.75 to 2.0.
2266
2267 * bootstrap: Add stdio-safer, unistd-safer modules.
2268 Remove m4/glibc2.m4 (introduced by latest gnulib, but
2269 we don't need it).
2270 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
2271 fopen-safer.c, stdio-safer.h, unistd-safer.h.
2272 * lib/subpipe.c: Include "unistd-safer.h".
2273 (create_subpipe): Make sure all the newly-created
2274 file descriptors are > 2, so that diagnostics don't
2275 get sent down them (which might cause Bison to hang, in theory).
2276 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
2277 * src/files.c (xfopen): Use fopen_safer, not fopen.
2278
2279 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
2280 yesterday's yacc.c fix.
2281
2282 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
2283
2284 * data/glr.c, data/lalr1.cc: Update copyright date.
2285
2286 Fix a destructor bug reported by Wolfgang Spraul in
2287 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
2288 * data/yacc.c (yyabortlab): Don't call destructor, and
2289 don't set yychar to EMPTY.
2290 (yyoverflowlab): Don't call destructor.
2291 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
2292 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
2293 since we no longer output the message "discarding lookahead token
2294 end of input ()".
2295
2296 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2297
2298 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
2299 fix a small glitch in debugging output.
2300 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
2301 after YY_SYMBOL_PRINT where needed.
2302
2303 (struct yyGLRState): Add some comments.
2304 (struct yySemanticOption): Add some comments.
2305 (union yyGLRStackItem): Add comment.
2306
2307 (yymergeOptionSets): Correct this to properly perform the union,
2308 avoiding infinite reported by Michael Rosien.
2309 Update comment.
2310
2311 * tests/glr-regression.at: Add test for GLR merging error reported
2312 by M. Rosien.

2355 Problem reported by Ralf Menzel.
2356
2357 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2358
2359 * tests/actions.at: Test that stack overflow invokes destructors.
2360 From Marcus Holland-Moritz.
2361 * data/yacc.c (yyerrlab): Move the code that destroys the stack
2362 from here....
2363 (yyreturn): to here. That way, destructors are called properly
2364 even if the stack overflows, or the user calls YYACCEPT or
2365 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
2366 (yyoverflowlab): Destroy the lookahead.
2367
2368 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
2369
2370 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
2371
2372 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
2373
2374 * NEWS: Bison-generated C parsers no longer quote literal strings
2375 associated with tokens.
2376 * src/output.c (prepare_symbols): Don't escape strings,
2377 since users don't want to see C escapes.
2378 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
2379 in diagnostics.
2380 * tests/input.at (Torturing the Scanner): Likewise.
2381 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
2382
2383 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
2384
2385 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
2386 the data size is known to be too small and we can't increase it.
2387 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
2388
2389 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
2390
2391 * src/parse-gram.y: Include quotearg.h.
2392 (string_as_id): Quote $1 before using it as a key, since the
2393 lexer no longer quotes it for us.
2394 (string_content): Don't strip quotes, since lexer no longer
2395 quotes it for us.
2396 * src/scan-gram.l: Include quotearg.h.
2397 ("\""): Omit quote.
2398 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
2399 a key, since the rest of the lexer doesn't quote it.
2400 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
2401 * tests/regression.at (Token definitions): Check for backslashes
2402 in token strings.
2403
2404 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
2405 (YYSIZE_T): Define to unsigned long int when using an older compiler.
2406 (yyparse): Revamp code to generate long syntax error message, to
2407 make it easier to translate, and to avoid problems with arithmetic
2408 overflow. Change "virtual memory" to "memory" in diagnostic, since
2409 we don't know whether the memory is virtual.
2410
2411 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2412
2413 * NEWS: Bison-generated C parsers now use the _ macro to
2414 translate strings.
2415 * data/yacc.c (_) [!defined _]: New macro.
2416 All English strings wrapped inside this macro.
2417 * doc/bison.texinfo (Bison Parser): Document _.
2418 * po/POTFILES.in: Include src/parse-gram.c, since it now
2419 includes translateable strings that parse-gram.y doesn't.
2420
2421 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
2422
2423 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
2424 reverting the 2004-10-11 change to this function.
2425 (symbol_check_alias_consistency): Don't call symbol_type_set
2426 if the type name is already correct.
2427 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
2428
2429 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
2430
2431 * tests/regression.at (Token definitions): Don't use a token named
2432 c, as that generates a "#define c ..." that runs afoul of buggy
2433 stdlib.h that uses the identifier c as a member of struct
2434 drand48_data. Problem reported by Horst Wente.
2435
2436 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
2437
2438 * bootstrap: Change translation URL from
2439 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
2440 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
2441 redirection glitches. Problem reported by twlevo@xs4all.nl.
2442
2443 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
2444
2445 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
2446 after operands; POSIX says this isn't portable for the c99 command.
2447
2448 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
2449
2450 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
2451 immediately if a data overrun has occurred; this may help us track
2452 down what may be a spurious failure on MacOS.
2453
2454 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
2455
2456 Respond to problems reported by twlevo@xs4all.nl.
2457

2459
2460 * src/vcg.h: Comment fix.
2461 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
2462 (G_CMAX): Change to -1 instead of INT_MAX.
2463
2464 * data/yacc.c (yyparse): Omit spaces before #line.
2465
2466 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
2467
2468 * src/tables.c (state_number_to_vector_number): Put it inside an
2469 "#if 0", since it's not currently used. Problem reported by
2470 Roland McGrath.
2471
2472 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
2473
2474 * src/output.c (escaped_output): Renamed from
2475 escaped_file_name_output, since we now use it for symbol tags as
2476 well. All uses changed.
2477 (symbol_destructors_output, symbol_printers_output):
2478 Escape symbol tags too.
2479 Problem reported by Matyas Forstner in
2480 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
2481
2482 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
2483 not needed.
2484 * src/output.c (user_actions_output, token_definitions_output,
2485 symbol_destructors_output, symbol_printers_output): Likewise.
2486 * src/reader.c (prologue_augment): Likewise.
2487 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
2488
2489 * src/vcg.c (output_edge): Don't quote linestyle arg.
2490 Problem reported by twlevo@xs4all.nl.
2491
2492 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
2493
2494 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
2495 example, reported by Derek M Jones. Also, make the example even
2496 more outrageous, to better illustrate how bad the problem is.
2497
2498 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
2499
2500 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
2501 putsym. Typo reported by Sebastian Piping.
2502
2503 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>

2507 Typos reported by Sebastian Piping via Justin Pence.
2508
2509 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2510
2511 * tests/glr-regression.at (Improper handling of embedded actions
2512 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
2513 embedded actions and $-N in GLR parsers", work around an Autoconf bug
2514 with dollar signs in test names.
2515 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
2516 for a similar reason.
2517
2518 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2519
2520 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
2521 wants to redefine G_VIEW.

2542 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2543
2544 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
2545 keyword; it's not needed with modern compilers, and it doesn't
2546 affect correctness with older compilers. Suggested by
2547 twlevo@xs4all.nl.
2548
2549 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
2550
2551 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
2552 gcc -Wswitch-default.
2553 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
2554 * data/yacc.c (yyparse): Likewise.
2555
2556 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
2557
2558 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
2559 already. Let config.h define any nonstandard values.
2560
2561 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
2562
2563 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
2564 for the benefit of slower hosts. Problem reported by
2565 Nelson H. F. Beebe.
2566
2567 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
2568
2569 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
2570 being defined and not used.
2571 * data/lalr1.cc (yyparse): Likewise.
2572 Use "if (false)" rather than "if (0)".
2573
2574 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
2575
2576 * TODO: Mention that we should allow NUL bytes in tokens.
2577
2578 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
2579
2580 * src/scan-skel.l (<<EOF>>): Don't close standard output.
2581 Problem reported by Hans Aberg.
2582
2583 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
2584
2585 * src/getargs.c (version): Happy new year; update overall
2586 program copyright date from 2004 to 2005.
2587
2588 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
2589 Problem reported by Hans Aberg.
2590 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
2591 (Output file names.): Add a test for the case when standard output
2592 is closed.
2593
2594 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
2595
2596 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
2597 to fix an oversight in the Bison 2.0 manual.
2598
2599 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
2600
2601 * NEWS: Version 2.0. Reformat the existing news items since
2602 1.875, so that related items are grouped together.
2603 * configure.ac (AC_INIT): Bump version to 2.0.
2604 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
2605
2606 * tests/torture.at (Exploding the Stack Size with Alloca): Set
2607 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
2608 otherwise, we're not testing alloca. Unfortunately there's no
2609 simple way to consult HAVE_ALLOCA here.
2610
2611 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
2612 for yymsg, too.
2613
2614 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
2615 hand. This avoids a warning about comparing int to size_t when
2616 GCC warnings are enabled.
2617
2618 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
2619
2620 * NEWS: Bison-generated parsers no longer default to using the
2621 alloca function (when available) to extend the parser stack, due
2622 to widespread problems in unchecked stack-overflow detection.
2623 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
2624 responsibility to set it to a positive value. This lets the user
2625 specify a value that is not a preprocessor constant.
2626 * data/yacc.c (YYMAXDEPTH): Likewise.
2627 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
2628 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
2629 to be a compile-time constant. However, explain the constraints on it.
2630 Also, explain the constraints on YYINITDEPTH.
2631 (Table of Symbols): Explain that alloca is no longer the default.
2632 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
2633 to 1.
2634
2635 * doc/bison.texinfo (Location Default Action): Mention that n must
2636 be zero when k is zero. Suggested by Frank Heckenbach.
2637
2638 2004-12-22 Akim Demaille <akim@epita.fr>
2639
2640 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
2641 (parser::state_type, parser::semantic_type, parser::location_type):
2642 Private, not public.
2643 (parser::parse): Return ints, not bool.
2644 Returning a bool introduces a problem: 0 corresponds to false, and
2645 it seems weird to return false on success. Returning true changes
2646 the conventions for yyparse.
2647 Alternatively we could return void and send an exception.
2648 There is no clear consensus (yet?).
2649 (state_stack, semantic_stack, location_stack): Rename as...
2650 (state_stack_type, semantic_stack_type, location_stack_type): these.
2651 Private, not public.
2652 * tests/c++.at: New.
2653 * tests/testsuite.at, tests/Makefile.am: Adjust.
2654
2655 2004-12-21 Akim Demaille <akim@epita.fr>
2656
2657 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
2658
2659 2004-12-21 Akim Demaille <akim@epita.fr>
2660
2661 Don't impose std::string for filenames.
2662
2663 * data/lalr1.cc (b4_filename_type): New.
2664 (position::filename): Use it.
2665 (parser.hh): Move the inclusion of stack.hh and location.hh below
2666 the user code, so that needed headers for the filename type can be
2667 included first.
2668 Forward declare them before the user code.
2669 * tests/Makefile.am (check-local, installcheck-local): Pass
2670 TESTSUITEFLAGS to the TESTSUITE.
2671
2672 2004-12-20 Akim Demaille <akim@epita.fr>
2673
2674 Use more STL like names: my_class instead of MyClass.
2675
2676 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
2677 (SemanticStack, SemanticType, StateStack, StateType)
2678 (TokenNumberType, Stack, Slice, Traits, Parser::location)
2679 (Parser::value): Rename as...
2680 (location_stack, location_type, rhs_number_type, semantic_stack)
2681 (semantic_type, state_stack, state_type, token_number_type, stack)
2682 (slice, traits, parser::yylloc, parser::yylval): these.
2683
2684 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
2685
2686 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
2687
2688 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
2689 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
2690
2691 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
2692
2693 Remove uses of 'short int' and 'unsigned short int'. This raises
2694 some arbitrary limits. It uses more memory but nowadays that's
2695 not much of an issue.
2696
2697 This change does not affect the generated parsers; that's a different
2698 task, as some users will want to conserve memory there.
2699
2700 Ideally we should use size_t to represent all object counts, and
2701 something like ptrdiff_t to represent signed differences of object
2702 counts; but that will require more code-cleanup than I have the
2703 time to do right now.
2704
2705 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
2706 Use size_t, not int or short int, to count objects.
2707 * src/closure.c (nritemset, closure): Likewise.
2708 * src/closure.h (nritemset, closure): Likewise.
2709 * src/nullable.c (nullable_compute): Likewise.
2710 * src/print.c (print_core): Likewise.
2711 * src/print_graph.c (print_core): Likewise.
2712 * src/state.c (state_compare, state_hash): Likewise.
2713 * src/state.h (struct state): Likewise.
2714 * src/tables.c (default_goto, goto_actions): Likewise.
2715
2716 * src/gram.h (rule_number, rule): Use int, not short int.
2717 * src/output.c (prepare_rules): Likewise.
2718 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
2719 errs, reductions): Likewise.
2720 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
2721 Likewise.
2722 * src/tables.c (vector_number, tally, action_number,
2723 ACTION_NUMBER_MINIMUM): Likewise.
2724 * src/output.c (muscle_insert_short_int_table): Remove.
2725
2726 2004-12-17 Akim Demaille <akim@epita.fr>
2727
2728 * data/lalr1.cc: Extensive Doxygenation.
2729 (error_): Rename as...
2730 (error): this, since it is visible to the user.
2731 Adjust callers.
2732 (Parser::message): Now an automatic variable from...
2733 (Parser::yyreport_syntax_error_): here.
2734 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
2735 Parser::error.
2736 * tests/input.at: Escape $.
2737
2738 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
2739
2740 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
2741 Parenthesize rhs to avoid obscure problems with mistakes like
2742 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
2743 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2744 b4_rhs_location): Likewise.
2745 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
2746 b4_rhs_location): Likewise.
2747
2748 2004-12-16 Akim Demaille <akim@epita.fr>
2749
2750 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
2751 yacc.c: be sure to stay within yycheck_.
2752 * tests/actions.at: Re-enable C++ tests.
2753
2754 2004-12-16 Akim Demaille <akim@epita.fr>
2755
2756 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
2757 real.
2758
2759 2004-12-16 Akim Demaille <akim@epita.fr>
2760
2761 Use #define to handle the %name-prefix.
2762
2763 * data/glr.c, data/yacc.c: Comment changes.
2764 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
2765 so that one can refer to yylex in the parser file, and have it
2766 renamed, as is the case with other skeletons.
2767
2768 2004-12-16 Akim Demaille <akim@epita.fr>
2769
2770 Move lalr1.cc internals into yy*.
2771
2772 * data/lalr1.cc (semantic_stack_, location_stack_, state_stack_)
2773 (semantic_stack_, location_stack_, pact_, pact_ninf_, defact_)
2774 (pgoto_, defgoto_, table_, table_ninf_, check_, stos_, r1_, r2_)
2775 (name_, rhs_, prhs_, rline_, token_number_, eof_, last_, nnts_)
2776 (empty_, final_, terror_, errcode_, ntokens_)
2777 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
2778 (looka_, ilooka_, error_range_, nerrs_):
2779 Rename as...
2780 (yysemantic_stack_, yylocation_stack_, yystate_stack_)
2781 (yysemantic_stack_, yylocation_stack_, yypact_, yypact_ninf_)
2782 (yydefact_, yypgoto_, yydefgoto_, yytable_, yytable_ninf_)

2788 these.
2789
2790 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
2791
2792 Fix some problems reported by twlevo at xs4all.
2793 * src/symtab.c (symbol_new): Report an error if the input grammar
2794 contains too many symbols. This is better than calling abort() later.
2795 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
2796 (struct node, struct graph):
2797 Rename member expand to stretch. All uses changed.
2798 (struct graph): Remove member layoutalgorithm. All uses removed.
2799 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
2800 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
2801 All uses changed.
2802 (N_STRETCH): Rename from N_EXPAND. All uses changed.
2803
2804 2004-12-15 Akim Demaille <akim@epita.fr>
2805

2807 Add more Doxygen comments.
2808 (symprint_, stack_print_, reduce_print_, destruct_, pop)
2809 (report_syntax_error_, translate_): Rename as...
2810 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
2811 (yypop_, yyreport_syntax_error_, yytranslate_): this.
2812
2813 2004-12-15 Akim Demaille <akim@epita.fr>
2814
2815 * data/lalr1.cc (lex_): Rename as...
2816 (yylex_): this.
2817 Move the trace here.
2818 Take the %name-prefix into account.
2819 Reported by Alexandre Duret-Lutz.
2820
2821 2004-12-15 Akim Demaille <akim@epita.fr>
2822
2823 Simplify the C++ parser constructor.
2824
2825 * data/lalr1.cc (debug_): Rename as...
2826 (yydebug_): so that the parser's internals are always in the yy*
2827 pseudo namespace.
2828 Adjust uses.
2829 (b4_parse_param_decl): Remove the leading comma as it is now only
2830 called as unique argument list.
2831 (Parser::Parser): Remove the constructor accepting a location and
2832 an initial debugging level.
2833 Remove from the other ctor the argument for the debugging level.
2834 (debug_level_type, debug_level, set_debug_level): New.
2835
2836 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
2837 constructor calls.
2838
2839 2004-12-15 Akim Demaille <akim@epita.fr>
2840
2841 Remove b4_root related material: failure experiment
2842 (which goal was to allow to derive from a class).
2843
2844 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
2845 definitions and uses.
2846
2847 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
2848
2849 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
2850 not 2, since it's not portable to subtract 1 from the start of an
2851 array. The new item 0 is never set or used. All uses changed.
2852
2853 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
2854 the default definition of YYLLOC_DEFAULT. Problem reported
2855 by Frank Heckenbach.
2856
2857 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
2858
2859 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
2860 the normal case and one for the error case. Just use the
2861 first one uniformly. Problem reported by Frank Heckenbach.
2862 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
2863 use exactly the same macro in both places.
2864 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
2865 so that the normal-case YYRHSLOC works for the error case too.
2866 All uses changed.
2867 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
2868 (YYLLOC_DEFAULT): Use the same macro as glr.c.
2869 * doc/bison.texinfo (Location Default Action): Don't claim that
2870 we have an array of locations. Use the same macro for both glr
2871 and lalr parsers. Mention YYRHSLOC. Mention what happens when
2872 the index is 0.
2873
2874 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
2875
2876 * HACKING: Update email addresses to send announcements to.
2877

2879
2880 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
2881
2882 * NEWS: Version 1.875e.
2883 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
2884
2885 * src/scan-skel.l: Include "complain.h", for "fatal".
2886
2887 * src/relation.h (relation_print, relation_digraph):
2888 Relation sizes are of type relation_node, not size_t (this is
2889 merely a doc fix, since the two types are equivalent).
2890 (relation_transpose): Relation sizes are of type relation_node,
2891 not int.
2892 * src/relation.c: Likewise.
2893 (top, infinity): Now of type relation_node, not int.
2894 (traverse, relation_transpose): Use relation_node, not int.
2895
2896 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
2897 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
2898 (yyparse): Remove unused local introduced in 2004-10-25 patch.
2899
2900 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
2901 specifying whether the test should be skipped. Use it tp
2902 specify that the [%defines %skeleton "lalr1.cc"] tests currently
2903 fail on some hosts, and should be skipped.
2904
2905 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
2906
2907 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
2908 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
2909 unless otherwise specified below.
2910
2911 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
2912 to allocate kernel_base, kernel_items, kernel_size, since
2913 they needn't be initialized to 0.
2914 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
2915 * src/closure.c (new_closure): Likewise, for itemset.
2916 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
2917 * src/lalr.c (set_goto_map): Likewise, for temp_map.
2918 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
2919 (build_relations): Likewise for edge, states1, includes.
2920 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
2921 * src/reader.c (packgram): Likewise, for ritem, rules.
2922 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
2923 * src/relation.c (relation_digraph): Likewise for VERTICES.
2924 (relation_transpose): Likewise for new_R, end_R.
2925 * src/symtab.c (symbols_token_translations_init): Likewise for
2926 token_translations.
2927 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
2928 (token_actions): Likewise for yydefact, actrow, conflrow,
2929 conflict_list.
2930 (save_column): Likewise for froms[symno], tos[symno].
2931 (goto_actions): Likewise for state_count.
2932 (pack_table): Likewise for base, pos, check.
2933 (tables_generate): Likewise for width.
2934
2935 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
2936 for initial core. Just have a separate core, so we needn't worry
2937 about whether kernel_size and kernel_base are initialized.
2938
2939 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
2940 kernel_size, kernel_items): Remove unnecessary initialization.
2941 * src/conflicts.c (conflicts): Likewise.
2942 * src/derives.c (derives): Likewise.
2943 * src/muscle_tablc (muscle_insert): Likewise.
2944 * src/relation.c (relation_digraph): Likewise.
2945 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
2946 conflrow, conflict_table, conflict_list, table, check):
2947 Likewise.
2948
2949 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
2950 This is because all callers pass unsigned int.
2951 * src/closure.h (new_closure): Likewise.
2952
2953 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
2954 (build_relations): Initialize includes[i] in all cases.
2955 * src/reader.c (packgram): Always initialize rules[ruleno].prec
2956 and rules[ruleno].precsym. Initialize members in order.
2957 * src/relation.c (relation_transpose): Always initialize new_R[i]
2958 and end_R[i].
2959 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
2960
2961 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
2962 conflict_list[0] was always 0, but now it isn't initialized.
2963
2964 * src/table.c (table_grow): When conflict_table grew, the grown
2965 area wasn't cleared. Fix this.
2966
2967 * lib/.cvsignore: Add strdup.c, strdup.h.
2968 * m4/.cvsignore: Add strdup.m4.
2969
2970 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
2971
2972 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
2973 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
2974 GOTO_NUMBER_MAXIMUM, since we occasionally compute
2975 ngotos + 1 without checking for overflow.
2976 (build_relations): Use END_NODE, not -1, to denote end of edges.
2977 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
2978 build_relations): Use goto_number, not int, for goto numbers.
2979 * src/tables.c (save_column, default_goto): Likewise.
2980
2981 2004-11-23 Akim Demaille <akim@epita.fr>
2982
2983 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
2984 of #defining from yystype.
2985 Don't typedef yystype, C++ does not need it.
2986 This lets it possible to forward declare it as union.
2987
2988 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
2989
2990 * bootstrap (gnulib_modules): Add extensions.
2991 Problem reported by Jim Meyering.
2992
2993 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
2994
2995 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
2996 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
2997 src/system.h, src/tables.c: XFREE -> free, to accommodate
2998 recent change to gnulib xalloc.h.
2999 Problem reported by Jim Meyering.
3000
3001 2004-11-17 Akim Demaille <akim@epita.fr>
3002
3003 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
3004
3005 2004-10-28 Akim Demaille <akim@epita.fr>,
3006 Alexandre Duret-Lutz <adl@gnu.org>
3007
3008 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
3009 changes.
3010 (YYCDEBUG): Adjust.
3011 Use it instead of cdebug_.
3012 (Parser::debug_stream, Parser::set_debug_stream): New.
3013 (Parser::symprint_): Define cdebug_ for temporary backward
3014 compatibility.
3015 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
3016 debug_stream ().
3017
3018 2004-11-17 Akim Demaille <akim@epita.fr>
3019
3020 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
3021 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
3022 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
3023 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
3024
3025 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
3026
3027 * data/glr.c (yyloc_default): Remove; not used.
3028 Problem reported by Frank Heckenbach.
3029
3030 2004-10-25 Akim Demaille <akim@epita.fr>
3031
3032 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
3033 Introduce another definition to address simple location arrays.
3034 (yyGLRStack): New member: yyerror_range.
3035 (yyrecoverSyntaxError, yyparse): Update it.
3036 (yyrecoverSyntaxError): Use it when shifting the error token to
3037 have an accurate range, equivalent to the one computed by both
3038 yacc.c and lalr1.cc.
3039 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
3040 that column numbers start at column 0, as per GNU Coding
3041 Standards, the others tests, and the doc.
3042 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
3043 Adjust to the above change (first column is 0).
3044 And adjust the location of the "<error>", now covering the whole
3045 line.
3046
3047 2004-10-22 Akim Demaille <akim@epita.fr>
3048 and Paul Eggert <eggert@cs.ucla.edu>
3049
3050 Remove some arbitrary limits on goto numbers and relations.
3051 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
3052 initial values, since they're never used.
3053 (set_goto_map): ngotos is now unsigned, so test for overflow
3054 by seeing whether it wraps around to zero.
3055 * src/lalr.h (goto_number): Now size_t, not short int.
3056 (GOTO_NUMBER_MAXIMUM): Remove.
3057 * src/relation.c (relation_print, traverse, relation_transpose):
3058 Check for END_NODE rather than looking at sign.
3059 * src/relation.h (END_NODE): New macro.
3060 (relation_node): Now size_t, not short int.
3061
3062 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
3063
3064 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
3065 keyword, not an identifier. Problem reported by Baron Schwartz in
3066 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
3067
3068 2004-10-11 Akim Demaille <akim@epita.fr>
3069
3070 * src/symtab.c (symbol_check_alias_consistency): Also check
3071 type names, destructors, and printers.
3072 Reported by Alexandre Duret-Lutz.
3073 Recode the handling of associativity and precedence in terms
3074 of symbol_precedence_set.
3075 Accept no redeclaration at all, not even equal to the previous
3076 value.
3077 (redeclaration): New.
3078 Use it to factor redeclaration complaints.
3079 (symbol_make_alias): Don't set the type of the alias, let
3080 symbol_check_alias_consistency do it as for other features.
3081 * src/symtab.h (symbol): Add new member prec_location, and
3082 type_location.
3083 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
3084 * tests/input.at (Incompatible Aliases): New.
3085
3086 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
3087
3088 .cvsignore fixes to accommodate gnulib changes,
3089 and the practice of naming build directories "_build".
3090 * .cvsignore: Add "_*". Sort.
3091 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
3092 * m4/.cvsignore: Add "*_gl.m4".
3093
3094 2004-10-06 Akim Demaille <akim@epita.fr>
3095
3096 * src/parse-gram.y (add_param): Fix the truncation of trailing
3097 spaces.
3098
3099 2004-10-05 Akim Demaille <akim@epita.fr>
3100
3101 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
3102 whether the reducion was empty or not. This leaves room to
3103 improve the use of YYLLOC_DEFAULT in such a case.
3104 lalr1.cc is still experimental, so changing this is acceptable.
3105 And finally, there are probably not many users who changed the
3106 handling of locations in GLR, so changing is admissible too.
3107
3108 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
3109 empty reduction, set @$ to an empty location ending the previously
3110 stacked symbol.
3111 Adjust uses to make sure the code is triggered on empty
3112 reductions.
3113 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
3114 expected output: empty reductions have empty locations.
3115
3116 2004-09-29 Akim Demaille <akim@epita.fr>
3117
3118 * data/lalr1.cc: Move towards a more standard C++ coding style
3119 for templates: Class < T > -> Class<T>.
3120
3121 2004-09-29 Akim Demaille <akim@epita.fr>
3122
3123 * data/lalr1.cc: Reinstall the former ctor, for sake of
3124 compatibility, but warn it will be removed.
3125 Move towards a more standard C++ coding style (i.e., type *var ->
3126 type* var).
3127
3128 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
3129
3130 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
3131 since it's less likely to work if NULs are involved in the future.
3132
3133 2004-09-27 Akim Demaille <akim@epita.fr>
3134
3135 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
3136
3137 2004-09-27 Akim Demaille <akim@epita.fr>
3138
3139 * data/lalr1.cc (b4_parse_param_decl_1): New.
3140 (b4_parse_param_decl): Use it to have different names between attribute
3141 and argument names.
3142 (b4_cc_constructor_call): Likewise.
3143
3144 2004-09-24 Akim Demaille <akim@epita.fr>
3145
3146 * src/parse-gram.y (add_param): Strip the leading and trailing
3147 blanks from a formal argument declaration.
3148 (YY_LOCATION_PRINT): New.
3149
3150 2004-09-24 Akim Demaille <akim@epita.fr>
3151
3152 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
3153 after the location.
3154
3155 2004-09-24 Akim Demaille <akim@epita.fr>
3156
3157 * doc/bison.texinfo (Table of Symbols): Sort.
3158
3159 2004-09-21 Akim Demaille <akim@epita.fr>
3160
3161 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
3162 the useless parentheses.
3163 Suggested by Paul Eggert.
3164
3165 2004-09-20 Akim Demaille <akim@epita.fr>
3166
3167 Let the initial-action act on the look-ahead, and use it for the
3168 "initial push" (corresponding to an hypothetical beginning-of-file).
3169 And let lalr1.cc honor %initial-action.
3170
3171 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
3172 example.
3173 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
3174 (Parser::Parser): Remove the ctor that used to initialize it.
3175 (Parser::parse): Like in the other skeletons, issue the "starting
3176 parse" message before any action.
3177 Honor %initial-action.
3178 Initialize the stacks with the lookahead.
3179 * data/yacc.c: Let $$ and @$ in %initial-action designate the
3180 look-ahead.
3181 Push them in the stacks.
3182 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
3183
3184 2004-09-20 Akim Demaille <akim@epita.fr>
3185
3186 * doc/bison.texinfo (Initial Action Decl): New.
3187
3188 2004-09-20 Akim Demaille <akim@epita.fr>
3189
3190 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
3191 clearer criterion to define it.
3192 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
3193 When reducing on an empty RHS, use the latest stacked location as
3194 location.
3195 yylloc is not always available.
3196 * data/glr.c: Likewise.
3197 Also, honor initial-actions.
3198
3199 2004-09-20 Akim Demaille <akim@epita.fr>
3200
3201 * data/yacc.c (YY_LOCATION_PRINT): New.
3202 Define when we know YYLTYPE's structure, i.e., when the default
3203 YYLLOC_DEFAULT is used.
3204 * data/c.m4 (b4_yysymprint_generate): Use it.
3205 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
3206 value of the result.
3207 (error_start_): Replace with...
3208 (error_range_): this location array.
3209 This allows to replace code relying on the implementation of
3210 locations by portable code.
3211 * data/yacc.c (yylerrsp): Replace with...
3212 (yyerror_range): this.
3213 Every time a token is popped, update yyerror_range[0], to have an
3214 accurate location for the error token.
3215 * data/glr.c (YY_LOCATION_PRINT): New.
3216 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
3217 deference a pointer.
3218 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
3219 report the location in %printers.
3220
3221 * src/scan-skel.l: Instead of abort, report error messages to ease
3222 understanding skeleton scanning failures.
3223
3224 2004-09-16 Akim Demaille <akim@epita.fr>
3225
3226 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
3227 (iterator, const_iterator): these, to be more in the C++ spirit.
3228 Also, return reverse iterators so that when displaying the stack
3229 we display its bottom first.
3230 (Parser::stack_print_, Parser::reduce_print_): Match the messages
3231 from yacc.c.
3232 We should probably use vector here though.
3233
3234 2004-09-16 Akim Demaille <akim@epita.fr>
3235
3236 Have more complete shift traces.
3237
3238 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
3239 to report Shifts instead of ad hoc YYDPRINTF invocations,
3240 including for the error token.
3241 * data/lalr1.cc (symprint_): Output the location.
3242 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
3243 output the location within the %printer.
3244 Activate GLR tests, at least to make sure they compile properly.
3245 They still don't pass though.
3246 * tests/calc.at: Adjust expect verbose output, since now "Entering
3247 state..." is on a different line than the "Shifting" message.
3248
3249 2004-09-08 Akim Demaille <akim@epita.fr>
3250
3251 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
3252 Bison directive from the Bison file to the invocation of this
3253 macro, so that these directives are passed to
3254 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
3255 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
3256 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
3257 the extra Bison directives instead of the whole series.
3258 Change the grammar so that there are recoverable errors, and
3259 unrecoverable errors. Now we can have the parser give up before
3260 consuming the whole input. As a result we now can observe that
3261 the lookahead is freed when needed.
3262 Change the parser source to parse argv[1] instead of a hard coded
3263 string.
3264 Simplify yylex, and give a value and location to EOF.
3265 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
3266 passed directives already coded in the file.
3267 Add some tests to check the location of "error".
3268 For some tests, the C++ parser is correct, and not yacc.c.
3269 For other tests, they provide different, but unsatisfying, values,
3270 so keep the C++ value so that at least one parser is "correct"
3271 according to the test suite.
3272 (Actions after errors): Remove, this is subsumed by the
3273 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
3274
3275 2004-09-06 Akim Demaille <akim@epita.fr>
3276
3277 * data/lalr1.cc: Adjust the indentation of the labels.
3278 (Parser::pop): New.
3279 Use it.
3280
3281 2004-09-06 Akim Demaille <akim@epita.fr>
3282
3283 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
3284 argument, an informative message.
3285 Call YY_SYMBOL_PRINT.
3286 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
3287 * data/lalr1.cc (destruct_): Likewise.
3288 In addition, no longer depend on b4_yysymprint_generate and
3289 b4_yydestruct_generate to generate these functions, do it "by
3290 hand".
3291
3292 2004-09-03 Akim Demaille <akim@epita.fr>
3293
3294 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
3295 invoked, yydestruct the lookahead.
3296 * tests/calc.at (Calculator $1): Update the expected lengths of
3297 traces: there is an added line for the discarded lookahead.
3298 * doc/bison.texinfo (Destructor Decl): Some rewording.
3299 Define "discarded" symbols.
3300
3301 2004-09-02 Akim Demaille <akim@epita.fr>
3302
3303 * data/lalr1.cc (translate_, destruct_): No reason to be static.
3304
3305 2004-09-02 Akim Demaille <akim@epita.fr>
3306
3307 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
3308 (YYDSYMPRINTF): Rename as...
3309 (YY_SYMBOL_PRINT): this.
3310 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
3311 two.
3312 Use it instead of direct symprint_ calls.
3313 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
3314 one.
3315
3316 2004-09-02 Akim Demaille <akim@epita.fr>
3317
3318 * data/lalr1.cc (b4_yysymprint_generate): New.
3319 (symprint_): New member function, defined when YYDEBUG.
3320 Use it consistently instead of token/nterm debugging output by
3321 hand.
3322 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
3323 %printer calls to use cdebug_ when using lalr1.cc.
3324
3325 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
3326
3327 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
3328 with #ifdef YYDEBUG.
3329
3330 2004-08-26 Akim Demaille <akim@epita.fr>
3331
3332 * doc/bison.texinfo (Implementing Loops): Rename as...
3333 (Implementing Gotos/Loops): this.
3334
3335 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
3336
3337 Adjust to latest gnulib.
3338 * bootstrap (gnulib_modules): Add xalloc-die.
3339 Set LC_ALL=C so that file names sort consistently.
3340 Prefer the gnulib copies of gettext.m4, glibc21.m4,
3341 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
3342 uintmax_t.m4, ulonglong.m4.
3343 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
3344 po.m4 since we are now using _gl.m4 instead.
3345
3346 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
3347
3348 * src/scan-action.l: Remove. Scanning of semantic actions is
3349 handled in scan-gram.l.
3350
3351 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
3352
3353 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
3354
3355 * src/location.h (struct): The file member is a uniqstr.
3356 (equal_boundaries): Use UNIQSTR_EQ for comparison.
3357
3358 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
3359
3360 Fix bug with non-%union parsers that have printers or destructors,
3361 which led to a Bison core dump. Reported by Peter Fales in
3362 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
3363
3364 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
3365 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
3366 not to our own type.
3367 * src/output.c (symbol_destructors_output, symbol_printers_output):
3368 Don't assume %union.
3369 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
3370 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
3371 UNION-FLAG. All callers changed.
3372 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
3373 Use type char, not unsigned int, when declaring an array of char;
3374 this lets us remove a cast.
3375 (Printers and Destructors): Add non-%union test cases.
3376
3377 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3378
3379 * doc/bison.texinfo: Minor editorial changes, mostly to the new
3380 GLR writeups. E.g., avoid frenchspacing and the future tense,
3381 change "lookahead" to "look-ahead", and change "wrt" to "with
3382 respect to".
3383
3384 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3385
3386 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
3387 New sections, split off from the GLR Parsers section. Put the new
3388 Simple GLR Parser near the start of the GLR section, for clarity.
3389 Rewrite connective text.
3390
3391 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
3392
3393 * doc/bison.texinfo (Simple GLR Parsers): New section.
3394
3395 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
3396
3397 * NEWS, TODO, doc/bison.texinfo:
3398 Use "look-ahead" instead of "lookahead", to be consistent.
3399 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,

3435 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
3436
3437 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
3438 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

3450
3451 Spent a few hours checking out which prerequisite versions the
3452 current sources actually require. I went all the way back to
3453 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
3454 a seemingly endless set of combinations of versions more recent
3455 than that. The bottom line is that the current sources require
3456 fairly recent versions of the build tools, and it'll be some work
3457 to change this.
3458 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
3459 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
3460 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
3461 Add comments explaining why those particular versions are
3462 currently needed.
3463
3464 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
3465 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
3466 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
3467
3468 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
3469 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
3470
3471 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3472
3473 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
3474 0.11.5. Suggested by Bruno Haible.
3475 * bootstrap: Remove gettext version checking.
3476
3477 * doc/bison.texinfo (Decl Summary): Also mention that %union
3478 can depend on prerequisite types. Problem reported by Tim
3479 Van Holder.
3480
3481 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3482
3483 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
3484 * README-alpha: Don't tell people not to package this.
3485
3486 * bootstrap: Don't assume $(...) works; use `...` instead.
3487 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
3488 gettext better.
3489
3490 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
3491 put into the -d output file, and mention what to do if YYSTYPE is
3492 defined as a macro.
3493
3494 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3495
3496 Undo change made earlier today: it caused autopoint to not bring
3497 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
3498 autopoint's.
3499
3500 * bootstrap: Check that gettext version matches what's in
3501 configure.ac. Warn users to ignore robots.txt ERROR 404.
3502 * bootstrap: Undo today's earlier change (logged below).
3503 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
3504
3505 The gettext version checking is causing more trouble than it's
3506 curing; remove it. Problem reported by Paul Hilfinger.
3507
3508 * bootstrap: Issue a warning that one can expect a message
3509 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
3510 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
3511
3512 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
3513
3514 Ensure that the C++ compiler used for testing actually works on a
3515 simple test program; if not, skip the C++-related tests. Problem
3516 reported by Vin Shelton in:
3517 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
3518
3519 * m4/cxx.m4: New file.

3522 * tests/local.at (AT_COMPILE_CXX): Use it.
3523
3524 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
3525
3526 * data/glr.c (yylloc): Output this macro even if locations are not
3527 being generated, as the GLR parser needs it even in that case.
3528 Problem reported by Troy A. Johnson
3529 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
3530
3531 * configure.ac (AC_INIT): Update to 1.875e.
3532
3533 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
3534
3535 * NEWS: Version 1.875d.
3536 * configure.ac (AC_INIT): Likewise.
3537 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
3538
3539 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
3540 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
3541 lalr1.cc runs afoul of the first, and the last two are no longer
3542 supported by GCC 3.4.0.
3543 * README: Mention GNU m4 1.4 or later; mention m4 patches.
3544 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
3545
3546 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
3547
3548 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

3557
3558 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
3559 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
3560 character and string literals.
3561 (unexpected_end): New function.
3562 (unexpected_eof): Use it.
3563 (unexpected_newline): New function.

3571 Remove more 'intl'-related files.
3572 Don't DEFUN AM_INTL_SUBDIR twice.
3573
3574 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
3575 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
3576 strtoul.c.
3577 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
3578 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
3579 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
3580 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
3581 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
3582 * src/.cvsignore: Add *.output.
3583
3584 * src/parse-gram.y: Put copyright notice inside %{ %} so it
3585 gets copied to the output file.
3586
3587 2004-04-28 Paul Eggert <eggert@twinsun.com>
3588
3589 Get files from the gnulib and po repositories, instead of relying
3590 on them being in our CVS. Upgrade to latest versions of gnulib
3591 and Automake.
3592
3593 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
3594 * bootstrap: Bootstrap from gnulib and po repositories.
3595 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
3596 * README-cvs: Document these changes. Remove version numbers from
3597 mentions of build tools, since they change so often. Mention Flex.
3598
3599 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
3600 (gl_USE_SYSTEM_EXTENSIONS): Add.
3601 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
3602 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
3603 does this for us.
3604 (AC_ISC_POSIX): Remove; we no longer support this
3605 ancient OS, as it gets in the way of latest Autoconf & gnulib.
3606 (AC_HEADER_STDC): Remove: we now assume C89 or better.
3607 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
3608 Do not check for C89 headers, except for locale.h which is used
3609 by the Yacc library and must port to K&R hosts.
3610 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
3611 Do not check for C89 functions, except for setlocale which is
3612 used by the Yacc library.
3613 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
3614 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,

3617 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
3618 AM_GNU_GETTEXT): Remove; now done by:
3619 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
3620 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
3621 for us.
3622
3623 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
3624 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
3625 Define to empty, as gnulib.mk will do the rest for us.
3626 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
3627 for us.
3628 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
3629 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
3630
3631 * src/files.c: Include gnulib's xstrndup.h.
3632
3633 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
3634 (REALLOC): Use xnrealloc, for likewise.
3635 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
3636 (strnlen, memrchr): Remove decls; functions no longer used.
3637 Include <stpcpy.h>.
3638
3639 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

3660 Remove, as these files are now generated automatically
3661 by bootstrap or automake.
3662
3663 * po/ChangeLog: Remove: all but one entry was a duplicate
3664 of this file, and I moved that 2000-11-02 entry here.
3665

3683 * src/.cvsignore: Remove *_.c.
3684
3685
3686 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
3687 support it. (The latest stable gzip doesn't.)
3688
3689 2004-04-27 Paul Eggert <eggert@twinsun.com>
3690
3691 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
3692 case, as stos_ is now used by destructors due to the 2004-02-09
3693 change.
3694
3695 Remove more K&R C support.
3696 * lib/libiberty.y (PARAMS): Remove. All uses removed.
3697 * lib/subpipe.c (errno): Remove decl.
3698 Include <stdlib.h> unconditionally.
3699 (EXIT_FAILURE): Remove macro.
3700 * src/complain.c (vfprintf, strerror): Remove.
3701 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
3702 unconditionally.
3703 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
3704 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
3705 (strchr, strspn, memchr): Remove decls.
3706 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
3707 unconditionally. Do not declare perror.
3708 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
3709 unconditionally.
3710
3711 * src/complain.c (_): Remove useless defn, as system.h defines this.

3714 with latest obstack.h.
3715 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
3716 to procedure types, as obstack.h now does that for us.
3717 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
3718
3719 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
3720 so that this include file can stand alone.
3721 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
3722 does this now. Include subpipe.h first after config.h, to
3723 test whether it can stand alone.
3724
3725 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
3726 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
3727 unused declaration.
3728
3729 * tests/synclines.at (%union synch line): Put a dummy member in
3730 the union, because empty unions aren't allowed in C. Caught
3731 by GCC 3.4.0.
3732
3733 2004-04-13 Jim Meyering <jim@meyering.net>
3734
3735 * src/conflicts.c (conflicts_print): Correct format string typo:

3777 muscle_insert_short_table. All uses changed.
3778
3779 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
3780
3781 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
3782 (declaration): Replace expected_conflicts with expected_sr_conflicts.
3783 Add %expect-rr rule.
3784
3785 * src/scan-gram.l: Recognize %expect-rr.
3786
3787 * src/conflicts.h (expected_sr_conflicts): Rename from
3788 expected_conflicts.

3793 (expected_rr_conflicts): Define.
3794 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
3795 for GLR parsers.
3796 Use expected_sr_conflicts in place of expected_conflicts.
3797 Warn if expected_rr_conflicts used in non-GLR parser.
3798
3799 * doc/bison.texinfo: Add documentation for %expect-rr.
3800
3801 2004-03-08 Paul Eggert <eggert@gnu.org>
3802
3803 Add support for hex token numbers. Suggested by Odd Arild Olsen in
3804 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
3805
3806 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
3807 in lalr1.cc.
3808 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
3809 * src/scan-gram.l (scan_integer): New function.
3810 ({int}): Use it.
3811 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
3812 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
3813 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
3814 Say "long int", not "long", for uniformity with GNU style.
3815
3816 2004-02-25 Paul Eggert <eggert@twinsun.com>
3817
3818 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
3819 compilers. This fixes a problem with Intel's C++ compiler being
3820 chatty, reported by Guido Trentalancia in
3821 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
3822
3823 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
3824
3825 Support %destructor and merge error locations in lalr1.cc.
3826
3827 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
3828 (Parser::stos_): Define unconditionally.
3829 (Parser::destruct_): New method. Generate its body with
3830 b4_yydestruct_generate.
3831 (Parser::error_start_): New attribute.
3832 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
3833 token which are discarded.
3834 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
3835 error_start_ when erroneous token are discarded.
3836 (Parser::parse) <yyerrlab1>: Compute the location of the error
3837 token so that it covers all the discarded tokens.
3838 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
3839 it can be called with `%skeleton "lalr1.cc"', and do that.
3840
3841 2004-02-02 Paul Eggert <eggert@twinsun.com>
3842
3843 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
3844 $(top_srcdir)/lib and ../lib. This fixes a bug reported
3845 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
3846 There's no need to mention top_builddir since Automake does that
3847 for us.
3848 (INCLUDES): Remove, as Automake says it's obsolescent.
3849 Contents migrated into AM_CPPFLAGS as described above.
3850 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
3851
3852 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
3853
3854 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
3855 (yyreportSyntaxError): Handle case where lookahead token is
3856 YYEMPTY.
3857
3858 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
3859
3860 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
3861 resulting parsers are compilable with C++.
3862
3863 2003-12-23 Paul Eggert <eggert@twinsun.com>
3864
3865 * config/depcomp, config/install-sh: Sync with Automake 1.8.
3866 * src/output.c (output_skeleton): Rename local var.
3867 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
3868 Bison tokens, as this runs afoul of the 2003-10-07 change that
3869 disallowed NUL bytes in character constants or string literals.
3870
3871 * tests/local.at: Require Autoconf 2.59's Autotest.
3872 * tests/testsuite.at: Don't include local.at, since we now assume
3873 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
3874 including it.
3875 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
3876 multiple inclusion warnings.
3877
3878 2003-12-02 Akim Demaille <akim@epita.fr>
3879
3880 * doc/bison.texinfo (How Can I Reset the Parser): More about start
3881 conditions.
3882 From Bruno Haible.
3883
3884 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
3885
3886 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
3887
3888 2003-10-07 Paul Eggert <eggert@twinsun.com>
3889
3890 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
3891 if testsuite doesn't exist.
3892
3893 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
3894 literals, unfortunately.
3895 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
3896 Complain about NUL bytes in character constants or string literals.
3897
3898 2003-10-05 Paul Eggert <eggert@twinsun.com>
3899
3900 * NEWS: Don't document %no-default-prec, as it's still
3901 too experimental.
3902 * doc/bison.texinfo: Document %no-default-prec only if
3903 the defaultprec flag is set. Normally it's not.
3904
3905 2003-10-04 Paul Eggert <eggert@twinsun.com>
3906
3907 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
3908 non-modifiable lvalue, instead of a modifiable one.
3909 * doc/bison.texinfo (Actions): Document that $$ can
3910 be assigned to. Do not claim that $$ and $N are
3911 array element references: user code should not rely on this.
3912
3913 2003-10-01 Paul Eggert <eggert@twinsun.com>
3914
3915 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
3916 (grammar_declaration): Use it.
3917 * src/scan-gram.l: New token %no-default-prec.
3918 * tests/conflicts.at: Revamp tests to use %no-default-prec.
3919 * NEWS, doc/bison.texinfo: Document the above.
3920
3921 2003-10-01 Akim Demaille <akim@epita.fr>
3922
3923 VCG no longer supports long_straight_phase.
3924
3925 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
3926 * src/print_graph.c (print_graph): Adjust.
3927
3928 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
3929 and Paul Eggert <eggert@twinsun.com>
3930

3941
3942 2003-09-30 Paul Eggert <eggert@twinsun.com>
3943
3944 * tests/testsuite.at: Include local.at, not input.at, fixing
3945 a typo in the 2003-08-25 patch.
3946
3947 2003-08-27 Akim Demaille <akim@epita.fr>
3948
3949 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
3950 GCC warnings.
3951
3952 2003-08-26 Akim Demaille <akim@epita.fr>
3953
3954 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
3955 "<\#" to avoid magic from Gnus when posting parts of this script.
3956
3957 2003-08-26 Akim Demaille <akim@epita.fr>
3958
3959 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
3960 (Parser::parse): here.
3961 Adjust: nerrs and errstatus is now replaced by...
3962 (Parser::nerrs_, Parser::errstatus_): New.

3964 2003-08-25 Akim Demaille <akim@epita.fr>
3965
3966 * config/announce-gen, Makefile.cfg: New.
3967 * Makefile.am: Adjust.

3969 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
3970
3971 2003-08-25 Akim Demaille <akim@epita.fr>
3972
3973 When reducing initial empty rules, Bison parser read an initial
3974 location that is not defined. This results in garbage, and that
3975 affects Bison's own parser. Therefore we need (i) to extend Bison
3976 to support a means to initialize this location, and (ii) to use
3977 this CVS Bison to fix CVS Bison's parser.
3978
3979 * src/reader.h, reader.c (epilogue_augment): Remove, replace
3980 with...
3981 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
3982 * src/parse-gram.y: Adjust.
3983 (%initial-action): New.
3984 (%error-verbose): Since we require CVS Bison, there is no reason
3985 not to use it.
3986 * src/scan-gram.l: Adjust.
3987 * src/Makefile.am (YACC): New, to make sure we use our own parser.
3988 * data/yacc.c (yyparse): Use b4_initial_action.
3989
3990 2003-08-25 Akim Demaille <akim@epita.fr>
3991
3992 * doc/bison.texinfo: Don't promote stdout for error messages.
3993
3994 2003-08-25 Akim Demaille <akim@epita.fr>
3995
3996 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
3997 From Alexandre Duret-Lutz.
3998
3999 2003-08-25 Akim Demaille <akim@epita.fr>

4001 Version 1.875c.
4002
4003 2003-08-25 Akim Demaille <akim@epita.fr>
4004
4005 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
4006 Use them.
4007
4008 2003-08-25 Akim Demaille <akim@epita.fr>
4009
4010 * data/lalr1.cc (Parser::reduce_print_): New.
4011 Use it.
4012
4013 2003-08-25 Akim Demaille <akim@epita.fr>
4014
4015 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
4016 error recovery loops. This patch is based on
4017 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
4018 Also, augment the similarity between lalr1.cc and yacc.c.
4019 Note: the locations of error recovery rules are not correct yet.
4020
4021 * data/lalr1.cc: Comment changes to augment the similarity between
4022 lalr1.cc and yacc.c.
4023 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
4024 (yyerrlab1): Remove, but where it used to be (now the bottom part of
4025 yyerrlab), when hitting EOF, pop the whole stack here instead of
4026 merely falling thru the default error handling mechanism.
4027 (yyerrorlab): New label, with the old contents of YYERROR,
4028 plus the following change: pop the stack of rhs corresponding
4029 to the production that invoked YYERROR. That is how Yacc
4030 behaves (required by POSIX).
4031 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
4032 fail.
4033
4034 2003-08-25 Akim Demaille <akim@epita.fr>
4035
4036 Tune local.at so that people can "autom4te -l autotest calc.at -o
4037 calc" for instance, to extract a sub test suite.
4038
4039 * tests/testsuite.at: Move the initialization, Autotest version
4040 requirement, and AT_TESTED invocation into...
4041 * tests/local.at: here.
4042 * tests/testsuite.at: Include it for compatibility with Autoconf
4043 2.57.
4044 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
4045 be ignore.
4046
4047 2003-08-04 Paul Eggert <eggert@twinsun.com>
4048
4049 Rework code slightly to avoid gcc -Wtraditional warnings.
4050 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
4051 The returned value is now stored in *YY0. All callers changed.
4052 * src/output.c (merge_output): Adjust to the above change.
4053
4054 2003-07-26 Paul Eggert <eggert@twinsun.com>
4055
4056 * data/glr.c (YYASSERT): New macro.
4057 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
4058 yyresolveStates, yyprocessOneStack):
4059 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
4060 Derived from a suggestion by Frank Heckenbach.
4061
4062 2003-07-25 Paul Eggert <eggert@twinsun.com>
4063
4064 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
4065 for portability to K&R C (after ansi2knr, presumably). See
4066 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
4067 by Frank Heckenbach, though I have omitted the structure-initialization
4068 part of his glr-knr.diff patch since I recall that the Portable
4069 C Compiler didn't require that change.
4070
4071 Let the user specify how to allocate and free memory.
4072 Derived from a suggestion by Frank Heckenbach in
4073 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
4074 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
4075 All uses of free, malloc, realloc changed to use these macros,
4076 and unnecessary casts removed.
4077 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
4078
4079 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
4080
4081 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
4082 use s.empty() rather than s == "" to test for empty string; see
4083 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
4084 (trivial change)
4085
4086 2003-06-25 Akim Demaille <akim@epita.fr>
4087
4088 * config/depcomp, config/install-sh: Update from masters.
4089
4090 2003-06-20 Paul Eggert <eggert@twinsun.com>
4091
4092 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
4093 and return properly parenthesized result.
4094 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
4095 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
4096 Remove unnecessary parentheses from uses.
4097 * doc/bison.texinfo (Location Default Action): Describe the
4098 conventions for parentheses.
4099
4100 2003-06-19 Paul Eggert <eggert@twinsun.com>
4101
4102 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
4103 yyreportTree): Do not assume that size_t is the same width as int,
4104 when printing sizes. Print sizes using an unsigned format.
4105 Problem reported by Frank Heckenbach in
4106 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
4107
4108 Port to Forte Developer 7 C compiler.
4109 * data/glr.c (struct YYLTYPE): If locations are not being used,
4110 declare a single dummy member, as empty structs do not conform
4111 to the C standard.
4112 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
4113 the Forte Developer 7 C compiler complains that end-of-loop
4114 code is not reached.
4115
4116 2003-06-17 Paul Eggert <eggert@twinsun.com>
4117
4118 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
4119 avoid warnings from picky compilers about redefinition of PARAMS.
4120
4121 2003-06-17 Paul Eggert <eggert@twinsun.com>
4122
4123 Version 1.875b.
4124
4125 * NEWS: Document 1.875b.
4126
4127 * lib/bbitset.h: Do not include config.h; that's the includer's job.
4128 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
4129 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
4130 Don't use 'index' in comments, as it's a builtin fn on some hosts.
4131 * lib/bitset_stats.c: Include gettext.h unconditionally, as
4132 per recent gettext manual's suggestion.
4133 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
4134 Use prototypes, not old-style definitions.
4135 * lib/lbitset.c (lbitset_unused_clear): Likewise.
4136 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
4137 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
4138 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,

4141 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
4142 vbitset_or_and_cmp, vbitset_copy): Likewise.

4156 from libbitset.
4157
4158 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
4159 `How Can I Reset @code{yyparse}', since texinfo does not allow
4160 arbitrary @ in node names.
4161
4162 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
4163 shouldn't be needed according to the gettext 0.12.1 documentation
4164 but which seem to be needed anyway: codeset.m4 glibc21.m4
4165 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
4166 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.

4168
4169 * lib/.cvsignore: Add stdbool.h.
4170 * m4/.cvsignore: Add nls.m4, po.m4.
4171
4172 Upgrade to CVS gnulib.

4174 * configure.ac (AM_STDBOOL_H): Invoke this instead of
4175 AC_HEADER_STDBOOL.
4176 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
4177 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
4178 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
4179 (MOSTLYCLEANFILES): New var.
4180 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).

4183 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
4184 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
4185 m4/quote.m4: Upgrade to today's gnulib.
4186
4187 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
4188 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
4189 the tests right now.
4190 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
4191 yyerror are declared before use; C99 requires this.
4192
4193 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4194
4195 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
4196 first.
4197 (yyrecoverSyntaxError): Correct the logic for setting and testing
4198 yyerrState.
4199 Correct comment on handling EOF.
4200 Allow states with only a default reduction, rather than failing
4201 (I can't quite reconstruct why these were not allowed before).
4202
4203 Fixes to avoid problem that $-N rules in GLR parsers can cause
4204 buffer overruns, corrupting state.
4205
4206 * src/output.c (prepare_rules): Output max_left_semantic_context
4207 definition.
4208 * src/reader.h (max_left_semantic_context): New variable declaration.
4209 * src/scan-gram.l (max_left_semantic_context): Define.
4210 (handle_action_dollar): Update max_left_semantic_context.
4211 * data/glr.c (YYMAXLEFT): New definition.
4212 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
4213 (yyresolveAction): Ditto.
4214
4215 Fixes to problems with location handling in GLR parsers reported by
4216 Frank Heckenbach (2003/06/05).
4217
4218 * data/glr.c (YYLTYPE): Make trivial if locations not used.
4219 (YYRHSLOC): Add parentheses, and define only if locations used.
4220 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
4221 locations not used.
4222 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
4223 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
4224
4225 * tests/cxx-type.at: Exercise location information; update tests
4226 to differentiate output with and without locations.
4227 Remove forward declarations of yylex and yyerror---caused errors
4228 because default YYLTYPE not yet defined.
4229 Change semantic actions to compute strings, rather than printing
4230 them directly (to test proper passing of semantics values). Change
4231 output to prefix notation and update test data and expected results.
4232 (yylex): Track locations.
4233 (stmtMerge): Return value rather than printing, and include arguments
4234 in value.
4235
4236 2003-06-03 Paul Eggert <eggert@twinsun.com>
4237
4238 Avoid warnings generated by GCC 2.95.4 when Bison is
4239 configured with --enable-gcc-warnings.
4240 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
4241 yy::]b4_parser_class_name[::translate_,
4242 yy::Stack::operator[] (unsigned),
4243 yy::Stack::operator[] (unsigned) const,
4244 yy::Slice::operator[] (unsigned),
4245 yy::Slice::operator[] (unsigned) const):
4246 Rename local vars to avoid warnings.
4247 * tests/glr-regression.at (Improper handling of embedded actions
4248 and $-N in GLR parsers): Remove unused local variable from yylex.
4249 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
4250 (void) as arg when not pure, since we now assume C89 when building
4251 Bison. Pacify GCC by using parameter.
4252
4253 2003-06-02 Paul Eggert <eggert@twinsun.com>
4254
4255 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
4256 yy::Location::lines, yy::Location::columns): Rename arguments
4257 to avoid shadowing; this removes a warning generated by GCC 3.3.
4258
4259 2003-06-01 Paul Eggert <eggert@twinsun.com>
4260
4261 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
4262 to g++, as GCC 3.3 complains if you do it.
4263 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
4264 everything that WARNING_CFLAGS has, except omit warnings
4265 not suitable for C++.
4266 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
4267 * tests/atlocal.in (CXXFLAGS): New var.
4268 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
4269
4270 Fix a GLR parser bug I reported in February; see
4271 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
4272 The problem was that GLR parsers did not conform to the C standard,
4273 because actions like { $1 = $2 + $3; } expanded to expressions
4274 that invoked YYFILL in separate subexpressions, and YYFILL assigned
4275 to a local variable. The C standard says that expressions
4276 like (var = f ()) + (var = f ()) have undefined behavior.
4277 Another problem was that GCC sometimes issues warnings that
4278 yyfill and its parameters are unused.
4279
4280 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
4281 as possibly unused.
4282 (yyfill): New function.
4283 (YYFILL): Use it.
4284 (yyuserAction): Change type of yynormal to bool, so that it matches
4285 the new yyfill signature. Mark it as possibly unused.
4286
4287
4288 Follow up on a bug I reported in February, where a Bison-generated
4289 parser can loop. Provide a test case and a fix for yacc.c. I
4290 don't have a fix for lalr1.cc or for glr.c, unfortunately.
4291 The original bug report is in:
4292 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
4293
4294 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
4295 macro's size was becoming unwieldy.
4296 (yyerrlab): Do not discard an empty lookahead symbol, as this
4297 might destroy garbage.
4298 (yyerrorlab): New label, with the old contents of YYERROR,
4299 plus the following change: pop the stack of rhs corresponding
4300 to the production that invoked YYERROR. That is how Yacc
4301 behaves, and POSIX requires this behavior.
4302 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
4303 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
4304 Define 'alarm' to do nothing if unistd.h is not available.
4305 Add a new rule "exp: '-' error;" to test the above change to
4306 data/yacc.c. Use 'alarm' to abort any test taking longer than
4307 10 seconds, as it's probably looping.
4308 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
4309 Also, the new yacc.c generates two fewer diagnostics for an
4310 existing test.
4311
4312 2003-05-24 Paul Eggert <eggert@twinsun.com>
4313
4314 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
4315 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
4316 This fixes a problem reported by John Bowman when the Compaq/HP
4317 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
4318 -ansi -Wall -gall).
4319 * data/yacc.c (union yyalloc): Likewise.
4320 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
4321
4322 Switch from 'int' to 'bool' where that makes sense.
4323

4327 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
4328 Return or accept bool, not int. All callers changed.

4333 bitset_or_and_cmp_): Likewise.
4334 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
4335 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
4336 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
4337 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
4338 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
4339 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
4340 bitset_stats_or_and_cmp): Likewise.
4341 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,

4343 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
4344 ebitset_xor_cmp): Likewise.
4345 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
4346 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
4347 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
4348 lbitset_xor_cmp): Likewise.
4349 * lib/bbitset.h: Include <stdbool.h>.
4350 (struct bitset_vtable): The following members now return bool, not
4351 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
4352 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
4353 or_and_cmp).
4354 * src/conflicts.c (count_rr_conflicts): Likewise.
4355 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
4356 All uses changed.
4357 * lib/ebitset.c (ebitset_obstack_init): Likewise.
4358 * lib/lbitset.c (lbitset_obstack_init): Likewise.
4359 * src/getargs.c (debug_flag, defines_flag, locations_flag,
4360 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4361 graph_flag): Likewise.
4362 * src/getargs.h (debug_flag, defines_flag, locations_flag,
4363 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
4364 graph_flag): Likewise.
4365 * src/output.c (error_verbose): Likewise.
4366 * src/output.h (error_verbose): Likewise.
4367 * src/reader.c (start_flag, typed): Likewise.
4368 * src/reader.h (typed): Likewise.
4369 * src/getargs.c (LOCATIONS_OPTION): New constant.
4370 (long_options, getargs): Use it.
4371 * src/lalr.c (build_relations): Use bool, not int.
4372 * src/nullable.c (nullable_compute): Likewise.
4373 * src/print.c (print_reductions): Likewise.
4374 * src/tables.c (action_row, pack_vector): Likewise.
4375 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
4376 * src/output.c (prepare): Use it.
4377 * src/output.c (token_definitions_output,
4378 symbol_destructors_output, symbol_destructors_output): Use string,
4379 not boolean integer, to keep track of whether to output separator.
4380 * src/print_graph.c (print_core): Likewise.
4381 * src/state.c (state_rule_lookaheads_print): Likewise.
4382
4383 * config/install-sh: Sync from automake 1.7.5.
4384
4385 2003-05-14 Paul Eggert <eggert@twinsun.com>
4386
4387 * src/parse-gram.y (rules_or_grammar_declaration): Require a
4388 semicolon after a grammar declaration, in the interest of possible
4389 future changes to the Bison input language.
4390 Do not allow a stray semicolon at the start of the grammar.
4391 (rhses.1): Allow one or more semicolons after any rule, including
4392 just before "|" as required by POSIX.
4393 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
4394 grammar.
4395
4396 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4397
4398 %parse-param support for lalr1.cc.
4399
4400 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
4401 b4_cc_constructor_calls, b4_cc_constructor_call,
4402 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
4403 definitions.
4404 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
4405 parse-param arguments.
4406 (yy::b4_parser_class_name): Declare instance variables to
4407 hold parse-param arguments.
4408 * tests/calc.at: s/value/semantic_value/ because value clashes
4409 with a member of yy::b4_parser_class_name. Adjust C++ code
4410 to handle %parse-param. Enable %parse-param test in C++.
4411
4412 2003-05-12 Paul Eggert <eggert@twinsun.com>
4413
4414 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
4415 English a bit. Fix fclose typo. Change "const char" to "char
4416 const", and use ANSI C rather than K&R for "main". Suggest
4417 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
4418 and suggest yy_switch_to_buffer.
4419
4420 2003-05-05 Paul Eggert <eggert@twinsun.com>
4421
4422 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
4423 C89. This avoids a diagnostic on compilers that define __STDC__
4424 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
4425 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4426
4427 2003-05-03 Paul Eggert <eggert@twinsun.com>
4428
4429 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
4430 Do not overrun array bounds.
4431 This should fix a bug reported today by Olatunji Oluwabukunmi in
4432 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
4433
4434 2003-04-29 Akim Demaille <akim@epita.fr>
4435
4436 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
4437 * src/getargs.c, src/getargs.h: here, as bool, not int.
4438 (nondeterministic_parser): New.
4439 * src/parse-gram.y, src/scan-gram.l: Support
4440 %nondeterministic-parser.
4441 * src/output.c (prepare): Use nondeterministic_parser instead
4442 of glr_parser where appropriate.
4443 * src/tables.c (conflict_row, action_row, save_row)
4444 (token_actions, token_actions, pack_vector): Ditto.
4445
4446 2003-04-29 Akim Demaille <akim@epita.fr>
4447
4448 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
4449
4450 2003-04-29 Akim Demaille <akim@epita.fr>
4451
4452 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
4453 with %pure-parser and %locations to exercise the patch from Yakov
4454 Markovitch below.
4455
4456 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
4457
4458 * data/yacc.c: (b4_lex_param): Corrected for the case where
4459 %lex-param is provided and %pure-parser isn't.
4460
4461 2003-04-27 Paul Eggert <eggert@twinsun.com>
4462
4463 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
4464 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
4465 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
4466 if it is not defined.
4467 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
4468
4469 2003-04-26 Paul Eggert <eggert@twinsun.com>
4470
4471 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
4472 Declare to be of type suitable for the ninf value itself, not of
4473 type suitable for the corresponding table, since the latter might
4474 be unsigned but the ninf value might be negative. This fixes a
4475 bug reported by Alexandre Duret-Lutz in
4476 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
4477
4478 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
4479 invokes it. We shouldn't invoke it twice because it will attempt
4480 to put error.o in the archive twice. This fixes a glitch reported
4481 by Martin Mokrejs in
4482 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
4483
4484 2003-04-21 Paul Eggert <eggert@twinsun.com>
4485
4486 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
4487 to gnulib.
4488
4489 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
4490
4491 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
4492 Fix obvious typo that results in uncompilable GLR parsers
4493 when both %pure-parser and %locations are used. (trivial change)
4494
4495 2003-04-17 Paul Eggert <eggert@twinsun.com>
4496
4497 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
4498 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
4499 Do not insert the expected token via unput, as this runs afoul
4500 of a POSIX-compatibility bug in flex 2.5.31.
4501 All uses changed to BEGIN the parent state,
4502 since we no longer insert the expected token via unput.
4503 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
4504 that is no longer emitted after the above change.
4505
4506 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
4507 the first one. This change is from Paul Hilfinger, and it fixes
4508 regression reported by Werner Lemberg in
4509 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
4510
4511 (resolve_sr_conflict): Don't invoke state_errs_set
4512 unless one or more tokens have been explicitly made errors.
4513 Otherwise, the above change causes Bison to abort.
4514
4515 * tests/existing.at (GNU pic Grammar): New test case, taken from
4516 Lemberg's email.
4517
4518 2003-03-31 Akim Demaille <akim@epita.fr>
4519
4520 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
4521
4522 2003-03-31 Akim Demaille <akim@epita.fr>
4523
4524 * src/output.c (prepare_symbols): Avoid trailing spaces in the
4525 output.
4526
4527 2003-03-31 Akim Demaille <akim@epita.fr>
4528
4529 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
4530 From Paul Hilfinger.
4531
4532 2003-03-29 Akim Demaille <akim@epita.fr>
4533
4534 * m4/error.m4: Do not put under dynamic conditions some code which
4535 expansion is under static control.
4536
4537 2003-03-29 Akim Demaille <akim@epita.fr>
4538
4539 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
4540
4541 2003-03-29 Akim Demaille <akim@epita.fr>
4542
4543 * doc/bison.texinfo (Strings are Destroyed): New.
4544
4545 2003-03-13 Paul Eggert <eggert@twinsun.com>
4546
4547 * .cvsignore: Add configure.lineno.
4548 * src/.cvsignore: Add yacc.
4549 * tests/.cvsignore: Add testsuite.log.
4550 * doc/fdl.texi: Sync with latest FSF version.
4551
4552 2003-03-12 Paul Eggert <eggert@twinsun.com>
4553
4554 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
4555 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
4556 cursor, instead of leaving it undefined. This fixes a bug
4557 reported by Tim Van Holder in
4558 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
4559 * tests/input.at (Torturing the Scanner): Test the scanner on
4560 an empty input file, which was Tim Van Holder's test case.
4561
4562 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
4563 <sys/resource.h> can be included, include sys/time.h and
4564 sys/times.h first, if available. This works around the SunOS
4565 4.1.4 porting bug reported by Bruce Becker in
4566 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
4567
4568 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
4569 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
4570 AC_HEADER_SYS_WAIT.
4571
4572 Merge changes from gnulib. This was prompted because the CVS
4573 snapshot didn't build on Solaris 7 due to strnlen problems.
4574
4575 These changes need to be merged back into gnulib:
4576 * lib/hash.c: Include <stdbool.h> unconditionally.
4577 * m4/onceonly.m4 (m4_quote): New macro.
4578 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
4579 Quote AC_FOREACH variable-expansions properly.
4580 The 2003-01-03 obstack.h change also needs merging.
4581 {end of changes requiring merging}
4582
4583 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
4584 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,

4616
4617 2003-03-03 Akim Demaille <akim@epita.fr>
4618
4619 * ro.po: New.
4620
4621 2003-03-02 Akim Demaille <akim@epita.fr>
4622
4623 * doc/bison.texinfo (Table of Symbols): Reactivate the
4624 documentation for %lex-param, and %parse-param.
4625
4626 2003-03-02 Akim Demaille <akim@epita.fr>
4627
4628 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
4629 generate verbose error messages.
4630 Use the number of tokens as an upper bound in yytname, as it
4631 cannot be a non terminal.
4632
4633 2003-03-02 Akim Demaille <akim@epita.fr>
4634
4635 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
4636 message.
4637
4638 2003-03-02 Akim Demaille <akim@epita.fr>

4640 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
4641 Use them to exercise yycheck overrun.
4642 Based on Andrew Suffield's grammar.
4643
4644 2003-03-02 Akim Demaille <akim@epita.fr>
4645
4646 Create tests/local.at for Bison generic testing macros.
4647
4648 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
4649 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
4650 This new file.
4651 * tests/calc.at (AT_CHECK_CALC): Adjust.

4653 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
4654 * tests/local.at: here.
4655 (AT_COMPILE_CXX): Tags the tests using it as c++.
4656 Ignore the test if CXX is not functional.
4657
4658 2003-03-01 Paul Eggert <eggert@twinsun.com>
4659
4660 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
4661 not loc->end, since loc->end might contain garbage and this leads
4662 to undefined behavior on some platforms.
4663 (id_loc, token_start): Use (IF_LINTed) initial values that do not
4664 depend on *loc, so that the reader doesn't give the the false
4665 impression that *loc is initialized.
4666 (<INITIAL>"%%"): Do not bother setting code_start, since its value
4667 does not survive the return.
4668
4669 2003-03-01 Akim Demaille <akim@epita.fr>
4670
4671 * src/scan-gram.l (code_start): Always initialize it when entering
4672 into yylex, as SC_EPILOGUE is activated *before* the corresponding
4673 yylex invocation. An alternative would be making it static, but
4674 then it starts with the second %%'s beginning, instead of its end.
4675
4676 2003-02-28 Paul Eggert <eggert@twinsun.com>
4677
4678 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
4679 around a UnixWare 7.1.1 porting bug reported by John Hughes in
4680 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
4681
4682 2003-02-26 Paul Eggert <eggert@twinsun.com>
4683
4684 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
4685 Remove Sequent/Pyramid discussion (nobody uses them any more).
4686 Merge VMS and MS-DOS discussion; these ports may well be dead
4687 but let's keep mentioning them for now. Put <> around email
4688 addresses. Add copyright notice.
4689
4690 2003-02-24 Paul Eggert <eggert@twinsun.com>
4691
4692 * data/glr.c (yy_reduce_print): yylineno -> yylno,
4693 to avoid collision with flex use of yylineno.

4702
4703 * data/lalr1.cc: Use temporary variables instead of casts to
4704 change integer types.
4705 Suggested by Paul Eggert.
4706
4707 2003-02-21 Akim Demaille <akim@epita.fr>
4708
4709 * doc/bison.texinfo: Use "location" consistently to refer to @n,
4710 to avoid confusions with lalr1.cc's notion of Position.
4711 Suggested by Paul Eggert.
4712
4713 2003-02-20 Akim Demaille <akim@epita.fr>
4714
4715 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
4716 before initial_columns.
4717 (location.hh): Use consistent variable names when defining the
4718 operator<<.
4719 Use "last" so that we subtract from Positions, not from unsigned.
4720
4721 2003-02-20 Akim Demaille <akim@epita.fr>
4722
4723 * data/lalr1.cc (position.hh): New subfile, including the extended
4724 and Doxygen'ed documentation of class Position.
4725 (location.hh): Use it.
4726 Document a` la Doxygen.

4731 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
4732 AT_YACC_IF.
4733 Redefine AT_YYERROR_SEES_LOC_IF using it.
4734 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
4735 not defined.
4736 Don't use the location in yy::Parser::error_ and
4737 yy::Parser::print_ when not %locations.
4738 Activate more lalr1.cc tests.
4739
4740 2003-02-19 Akim Demaille <akim@epita.fr>
4741
4742 * data/lalr1.cc: When displaying a line number, be sure to make it
4743 an int.
4744
4745 2003-02-19 Akim Demaille <akim@epita.fr>
4746
4747 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
4748 Remove, useless.
4749 (YYABORT, YYACCEPT, YYERROR): New.
4750 * tests/calc.at: Renable the lalr1.cc test.
4751
4752 2003-02-19 Akim Demaille <akim@epita.fr>

4755 error recovery, mixing with/without pops and discarding of the
4756 lookahead.
4757 Exercise YYERROR.
4758 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
4759
4760 2003-02-17 Paul Eggert <eggert@twinsun.com>
4761
4762 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
4763 * tests/testsuite.at (AT_COMPILE): Use them.
4764 This fixes the testsuite problem reported by Robert Lentz in
4765 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
4766
4767 2003-02-12 Paul Eggert <eggert@twinsun.com>
4768
4769 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
4770 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
4771 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
4772 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
4773 Check for malloc failure, for consistency with yacc.c.
4774 (yytname_size): Remove, for consistency with yacc.c.
4775
4776 The bug still remains in data/lalr1.cc, as I didn't have time
4777 to fix it there.
4778
4779 2003-02-06 Akim Demaille <akim@epita.fr>
4780
4781 * configure.ac (GXX): Rename as...
4782 (CXX): this, to keep the original Autoconf semantics.
4783 Require 2.57.
4784 * data/lalr1.cc: Fix b4_copyright invocations.

4792 (Location::begin, Location::end): these, to mock the conventional
4793 iterator names.
4794 (operator<< (Location)): New.
4795 * tests/atlocal.in (CXX): New.
4796 * tests/testsuite.at (AT_COMPILE_CXX): New.
4797 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
4798 locations in a more synthetic way.
4799 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
4800 lalr1.cc is used.
4801 Adjust the C locations to match those from Emacs: first column is
4802 column 0.
4803 Change all the expected results.
4804 Conform to the GCS: simplify the locations when applicable.
4805 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
4806 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
4807 these CPP macros with the m4 macros new defined by...
4808 (AT_CHECK_PUSHDEFS): this, i.e.:
4809 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
4810 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
4811 New macros.
4812 (AT_CHECK_POPDEFS): Undefine them.
4813 (AT_CHECK_CALC_LALR1_CC): New.
4814 Use it for the first lalr1.cc test.
4815
4816 2003-02-04 Akim Demaille <akim@epita.fr>
4817
4818 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
4819 Location as is defined.
4820
4821 2003-02-04 Akim Demaille <akim@epita.fr>
4822
4823 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
4824 name_ being defined.
4825
4826 2003-02-03 Paul Eggert <eggert@twinsun.com>
4827
4828 * src/gram.h (start_symbol): Remove unused decl.
4829
4830 Use more-consistent naming conventions for local vars.
4831
4832 * src/derives.c (derives_compute): Change type of local var from
4833 int to rule_number.
4834 * src/gram.c (grammar_rules_partial_print): Likewise.
4835 * src/print.c (print_core): Likewise.
4836 * src/reduce.c (reduce_grammar_tables): Likewise.
4837

4844 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
4845 for symbol or symbol_number var.
4846 * src/reader.c (grammar_start_symbol_set): Likewise.
4847 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
4848 Likewise.
4849 * src/state.c (transitions_to): Likewise.
4850 * src/state.h: Likewise.
4851 * src/tables.c (symbol_number_to_vector_number): Likewise.
4852
4853 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
4854 char * var.
4855
4856 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
4857 var.
4858
4859 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
4860 var.
4861
4862 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
4863 Use str, not s, for char * var. Use ch, not c, for character var.

4874 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
4875 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
4876 param to have same name as that of enum, so that we don't use
4877 "s" to stand for a non-state.
4878
4879 2003-02-02 Akim Demaille <akim@epita.fr>
4880
4881 * src/scan-skel.l: Scan more than one inert character per yylex
4882 invocation.
4883
4884 2003-02-01 Paul Eggert <eggert@twinsun.com>
4885
4886 Version 1.875a.
4887
4888 * po/LINGUAS: Add ms.
4889
4890 2003-01-30 Akim Demaille <akim@epita.fr>
4891
4892 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
4893
4894 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4895
4896 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
4897 of $1.
4898
4899 Changes in response to error report by S. Eken: GLR mode does not
4900 handle negative $ indices or $ indices in embedded rules correctly.
4901 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
4902
4903 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
4904 (b4_rhs_location): Ditto.
4905 (yyfill): New function to copy from stack tree into array
4906 incrementally.
4907 (yyuserAction): Modify to allow incremental move of semantic values
4908 to rhs array when in GLR mode.
4909 Define YYFILL to use in user-defined actions to fill semantic array
4910 as needed.
4911 Remove dummy use of yystack, as there is now a guaranteed use.
4912 (yydoAction): Modify to allow incremental move of semantic values
4913 to rhs array when in GLR mode.
4914 (yyresolveAction): Ditto.
4915 (yyglrShiftDefer): Update comment.
4916 (yyresolveStates): Use X == NULL for pointers, not !X.
4917 (yyglrReduce): Ditto.
4918 (yydoAction): Ditto
4919
4920 * tests/glr-regr1.at: Rename to ...
4921 * tests/glr-regression.at: Add new regression test for the problems
4922 described above (adapted from S. Eken).
4923 Update copyright notice.
4924 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
4925 * tests/Makefile.am: Ditto.
4926
4927 2003-01-28 Paul Eggert <eggert@twinsun.com>
4928
4929 * data/lalr1.cc: Do not use @output_header_name@ unless
4930 b4_defines_flag is set. This fixes two bugs reported by
4931 Tim Van Holder in
4932 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
4933 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
4934
4935 2003-01-21 Paul Eggert <eggert@twinsun.com>
4936
4937 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
4938 we don't need to worry about yyerrlab1 being reported as an
4939 "unused label" by non-GCC C compilers. The downside is that if
4940 locations are used then a couple of statements are duplicated each
4941 time YYERROR is invoked, but the upside is that the warnings
4942 should vanish.
4943 (yyerrlab1): Move code to YERROR.
4944 (yyerrlab2): Remove. Change uses back to yyerrlab1.
4945 This reverts some of the 2002-12-27 change.
4946
4947 2003-01-17 Paul Eggert <eggert@twinsun.com>
4948
4949 * src/output.c (symbol_printers_output): Fix typo that led
4950 to core dump. Problem reported by Antonio Rus in
4951 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
4952
4953 2003-01-13 Akim Demaille <akim@epita.fr>,
4954 Quoc Peyrot <chojin@lrde.epita.fr>,
4955 Robert Anisko <anisko_r@lrde.epita.fr>
4956
4957 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
4958 when the stacks contain one element, as the loop would otherwise
4959 free the last state, and then use the top state (the one we just
4960 popped). This means that the initial elements will not be freed
4961 explicitly, as is the case in yacc.c; it is not a problem, as
4962 these elements have fake values.
4963
4964 2003-01-11 Paul Eggert <eggert@twinsun.com>
4965
4966 * NEWS: %expect-violations are now just warnings, reverting
4967 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
4968 bootstrapping problem reported by Matthias Klose; see
4969 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
4970 * src/conflicts.c (conflicts_print): Likewise.
4971 * tests/conflicts.at (%expect not enough, %expect too much,
4972 %expect with reduce conflicts): Likewise.
4973 * doc/bison.texinfo (Expect Decl): Document this. Also mention
4974 that the warning is enabled if the number of conflicts changes
4975 (not necessarily increases).
4976
4977 * src/getargs.c (version): Update copyright year.
4978
4979 2003-01-09 Akim Demaille <akim@epita.fr>
4980
4981 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
4982
4983 2003-01-08 Paul Eggert <eggert@twinsun.com>
4984
4985 * Makefile.maint (WGETFLAGS):
4986 New macro, containing "-C off" to disable proxy caches.
4987 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
4988 (rel-check): Use $(WGET) instead of wget.
4989
4990 2003-01-06 Paul Eggert <eggert@twinsun.com>
4991
4992 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
4993 the GLR paper of Scott, Johnstone and Hussain.
4994
4995 2003-01-04 Paul Eggert <eggert@twinsun.com>
4996
4997 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
4998 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
4999 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
5000 (EXTRA_LIBRARIES): New var, for liby.a.
5001 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
5002 (EXTRA_SCRIPTS): New var, for yacc.
5003
5004 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
5005 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
5006 Problem reported by Nelson H. F. Beebe.
5007
5008 2003-01-03 Paul Eggert <eggert@twinsun.com>
5009
5010 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
5011 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
5012 when compiling Bison 1.875's `bitset bset = obstack_alloc
5013 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
5014
5015 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
5016 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
5017 grow to a huge size with typical invocation.
5018
5019 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
5020 Use the pattern recommended by Autoconf 2.57, except also protect
5021 against double-definition.
5022 * src/system.h: Likewise.
5023 Portability issues reported by Nelson H. F. Beebe.
5024
5025 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
5026 All uses changed. Provide a definition in both C and C++.
5027 (yytrue, yyfalse): Define even if defined (__cplusplus).
5028
5029 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
5030 Reported by Nelson H. F. Beebe.
5031
5032 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
5033
5034 2003-01-02 Paul Eggert <eggert@twinsun.com>
5035
5036 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
5037 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
5038 Bug reported by Nelson H. F. Beebe.
5039
5040 2003-01-01 Paul Eggert <eggert@twinsun.com>
5041
5042 * Version 1.875.
5043
5044 2002-12-30 Paul Eggert <eggert@twinsun.com>
5045
5046 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
5047 Moved here from...
5048 (<INITIAL>","): Here. This causes stray "," to be treated
5049 more uniformly.
5050
5051 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
5052 last brace in braced code when not in Yacc mode, for compatibility
5053 with Bison 1.35. This resurrects the 2001-12-15 patch to
5054 src/reader.c.
5055
5056 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
5057 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
5058
5059 2002-12-28 Paul Eggert <eggert@twinsun.com>
5060
5061 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
5062 that of SYM's type. This fixes Debian bug 168069, reported by
5063 Thomas Olsson.
5064
5065 2002-12-28 Paul Eggert <eggert@twinsun.com>
5066
5067 Version 1.75f.
5068
5069 Switch back to the Yacc style of conflict reports, undoing some
5070 of the 2002-07-30 change.
5071 * doc/bison.texinfo (Understanding): Use Yacc style for
5072 conflict reports. Also, use new way of locating rules.
5073 * src/conflicts.c (conflict_report):
5074 Renamed from conflict_report_yacc, removing the old
5075 'conflict_report'. Translate the entire conflict report at once,
5076 so that we don't assume that "," has the same interpretation in
5077 all languages.
5078 (conflicts_output): Use Yacc-style conflict report for each state,
5079 instead of our more-complicated style.
5080 (conflicts_print): Use Yacc-style conflict report, except print
5081 the input file name when not emulating Yacc.
5082 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
5083 Conflicted Reduction, %expect not enough, %expect too much,
5084 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
5085 * tests/existing.at (GNU Cim Grammar): Likewise.
5086 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
5087
5088 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
5089 fatal): Don't invoke fflush; it's not needed and it might even be
5090 harmful for stdout, as stdout might not be open.
5091 * src/reduce.c (reduce_print): Likewise.
5092
5093 2002-12-27 Paul Eggert <eggert@twinsun.com>
5094
5095 Fix a bug where error locations were not being recorded correctly.
5096 This problem was originally reported by Paul Hilfinger in
5097 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
5098
5099 * data/yacc.c (yyparse): New local var yylerrsp, to record the
5100 top of the location stack's error locations.
5101 (yyerrlab): Set it. When discarding a token, push its location
5102 onto yylerrsp so that we don't lose track of the error's end.
5103 (yyerrlab1): Now is only the target of YYERROR, so that we can
5104 properly record the location of the action that failed. For GCC
5105 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
5106 GCC warning about yyerrlab1 being unused if YYERROR is unused.
5107 (yyerrlab2): New label, which yyerrlab now falls through to.
5108 Compute the error's location by applying YYLLOC_DEFAULT to
5109 the locations of all the symbols that went into the error.
5110 * doc/bison.texinfo (Location Default Action): Mention that
5111 YYLLOC_DEFAULT is also invoked for syntax errors.
5112 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
5113 Error locations include the locations of all the tokens that were
5114 discarded, not just the last token.
5115
5116 2002-12-26 Paul Eggert <eggert@twinsun.com>
5117
5118 * src/files.c: Include quote.h.
5119 (compute_output_file_names): Warn if we detect conflicting
5120 outputs to the same file. This should catch the misunderstanding
5121 exemplified by Debian Bug 165349, reported by Bruce Stephens..
5122
5123 * src/conflicts.c (conflicts_print): If the user specifies
5124 "%expect N", report an error if there are any reduce/reduce
5125 conflicts. This is what the manual says should happen.
5126 This fixes Debian bug 130890, reported by Anthony DeRobertis.
5127 * tests/conflicts.at (%expect with reduce conflicts): New test.
5128
5129 Don't use m4_include on relative file names, as it doesn't work as
5130 desired if there happens to be a file with that name under ".".
5131
5132 * m4sugar/version.m4: Remove; it was included but it wasn't used.
5133 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
5134 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
5135 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
5136 * src/output.c (output_skeleton): Use full path names when
5137 specifying a file to include; don't rely on include path, as
5138 it's unreliable when the working file contains a file with
5139 that name.
5140
5141 2002-12-25 Paul Eggert <eggert@twinsun.com>
5142
5143 Remove obsolete references to bison.simple and bison.hairy.
5144 Problem mentioned by Aubin Mahe in
5145 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
5146 * data/glr.c: Comment fix.
5147 * doc/bison.1: Remove references. Also, mention "yacc".
5148
5149 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
5150 with -g option.
5151
5152 * src/parse-gram.y (declaration): Use enum "report_states" rather
5153 than its numeric value 1.
5154
5155 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
5156 opening a new one. This fixes Debian bug 165349, reported by
5157 Bruce Stephens.
5158
5159 2002-12-24 Paul Eggert <eggert@twinsun.com>
5160
5161 Version 1.75e.
5162
5163 * Makefile.maint (cvs-update): Don't assume that the shell
5164 supports $(...), as Solaris sh doesn't.
5165
5166 * src/parse-gram.y (lloc_default): Remove test for empty
5167 nonterminals at the end, since it didn't change the result.
5168
5169 2002-12-24 Paul Eggert <eggert@twinsun.com>
5170
5171 If the user does not define YYSTYPE as a macro, Bison now declares it
5172 using typedef instead of defining it as a macro. POSIX requires this.
5173 For consistency, YYLTYPE is also declared instead of defined.
5174
5175 %union directives can now have a tag before the `{', e.g., the
5176 directive `%union foo {...}' now generates the C code
5177 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
5178 The default union tag is `YYSTYPE', for compatibility with Solaris 9
5179 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
5180 instead of `yyltype'.
5181
5182 `yystype' and `yyltype' are now obsolescent macros instead of being
5183 typedefs or tags; they are no longer documented and will be
5184 withdrawn in a future release.
5185
5186 * data/glr.c (b4_location_type): Remove.
5187 (YYSTYPE): Renamed from yystype.
5188 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
5189 (struct YYLTYPE): Renamed from struct yyltype.
5190 (YYLTYPE): Renamed from yyltype.
5191 (yyltype, yystype): New (and obsolescent) macros,
5192 for backward compatibility.
5193 * data/yacc.c: Likewise.
5194
5195 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
5196 does not specify a union tag. This is for compatibility with
5197 Solaris 9 yacc.
5198
5199 * src/parse-gram.y (add_param): 2nd arg is now char * not char
5200 const *, since it is now modified by stripping surrounding { }.
5201 (current_braced_code): Remove.
5202 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
5203 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
5204 trailing " {...}". Now of type <chars>.
5205 (grammar_declaration): Adjust to bundled tokens.
5206 (code_content): Remove; stripping is now done by add_param.
5207 (print_token_value): Print contents of bundled tokens.
5208 (token_name): New function.
5209
5210 * src/reader.h (braced_code, current_braced_code): Remove.
5211 (token_name): New decl.
5212
5213 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
5214 token_type, not braced_code code_kind. All uses changed.
5215 (SC_PRE_CODE): New state, for scanning after a keyword that
5216 has (or usually has) an immediately-following braced code.
5217 (token_type): New local var, to keep track of which token type
5218 to return when scanning braced code.
5219 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
5220 <INITIAL>"%parse-param", <INITIAL>"%printer",
5221 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
5222 instead of returning a token type immediately.
5223 (<INITIAL>"{"): Set token type.
5224 (<SC_BRACED_CODE>"}"): Use it.
5225 (handle_action_dollar, handle_action_at): Now returns bool
5226 indicating success. Fail if ! current_rule; this prevents a core dump.
5227 (handle_symbol_code_dollar, handle_symbol_code_at):
5228 Remove; merge body into caller.
5229 (handle_dollar, handle_at): Complain in invalid contexts.
5230
5231 * NEWS, doc/bison.texinfo: Document the above.
5232 * NEWS: Fix years and program names in copyright notice.
5233
5234 2002-12-17 Paul Eggert <eggert@twinsun.com>
5235
5236 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
5237 Reporting, Table of Symbols): Omit mentions of %lex-param and
5238 %parse-param from the documentation for now.
5239
5240 2002-12-15 Paul Eggert <eggert@twinsun.com>
5241
5242 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
5243 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
5244 lookahead symbol, and which sets yychar in parser actions) and it
5245 disagreed with the Bison documentation. Bug
5246 reported by Andrew Walrond.
5247
5248 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
5249 as the caller now does that.
5250 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
5251 (YYEMPTY): Parenthesize right hand side, since others use it.
5252 (yyparse): Don't assume that our generated code is the only code
5253 that sets yychar.
5254
5255 2002-12-13 Paul Eggert <eggert@twinsun.com>
5256
5257 Version 1.75d.
5258
5259 POSIX requires a "yacc" command.
5260 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
5261 (MOSTLYCLEANFILES): Add yacc.
5262 (yacc): New rule.
5263 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
5264 as an alias for bison y.
5265
5266 * po/LINGUAS: Add da.
5267
5268 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
5269 problem with latest <getopt.h>.
5270 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
5271
5272 * doc/fdl.texi: Upgrade to 1.2.
5273 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
5274 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
5275 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
5276 gnulib.
5277 * config/install-sh: Sync with autotools.
5278
5279 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
5280 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5281 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
5282 locations are requested.
5283 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
5284 locations are requested.
5285
5286 2002-12-12 Paul Eggert <eggert@twinsun.com>
5287
5288 Remove unportable casts and storage allocation tricks.
5289 While we're at it, remove almost all casts, since they
5290 usually aren't needed and are a sign of trouble.
5291
5292 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
5293
5294 * src/derives.c (derives_compute): Do not subtract NTOKENS from
5295 the pointer DSET returned by malloc; this isn't portable.
5296 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
5297 Similarly for DERIVES.
5298 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
5299 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
5300 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
5301
5302 * src/derives.c (derives_compute): Do not bother invoking
5303 int_of_rule_number, since rule numbers are integers.
5304
5305 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
5306 rather than XMALLOC (char, N).
5307
5308 * src/files.c (filename_split): Rewrite to avoid cast.
5309
5310 * src/gram.h (symbol_number_as_item_number,
5311 item_number_as_symbol_number, rule_number_as_item_number,
5312 item_number_as_rule_number):
5313 Now inline functions rather than macros, to avoid casts.
5314 * src/state.h (state_number_as_int): Likewise.
5315 * src/tables.c (state_number_to_vector_number,
5316 symbol_number_to_vector_number): Likewise.
5317
5318 * src/gram.h (int_of_rule_number): Remove; no longer used.
5319
5320 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
5321 since the resulting storage is always stored into.
5322
5323 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
5324 where it's needed.
5325
5326 * src/muscle_tab.c (muscle_m4_output):
5327 Now inline. Return bool, not int.
5328 * src/state.c (state_compare): Likewise.
5329 * src/symtab.c (symbol_check_defined,
5330 symbol_check_alias_consistency, symbol_pack, symbol_translation,
5331 hash_compare_symbol, hash_symbol):
5332 Likewise.
5333 * src/uniqstr.c (uniqstr_print): Likewise.
5334 * src/muscle_tab.c (muscle_m4_output_processor):
5335 New function, to avoid casts.
5336 * src/state.c (state_comparator, stage_hasher): Likewise.
5337 * src/symtab.c (symbol_check_defined_processor,
5338 symbol_check_alias_consistency_processor, symbol_pack_processor,
5339 symbol_translation_processor, hash_symbol_comparator,
5340 hash_symbol_hasher): Likewise.
5341 * src/uniqstr.c (uniqstr_print_processor): Likewise.
5342 * src/muscle_tab.c (muscles_m4_output):
5343 Use new functions instead of casting old functions unportably.
5344 * src/state.c (state_hash_new): Likewise.
5345 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
5346 symbols_token_translations_init):
5347 Likewise.
5348 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
5349
5350 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
5351 var instead of casting to long, to avoid casts.
5352 (prepare_states): Use MALLOC rather than alloca, so that we don't
5353 have to worry about alloca.
5354 * src/state.c (state_hash_lookup): Likewise.
5355
5356 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
5357 local var instead of casting to unsigned char, to avoid casts.
5358
5359 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
5360 STATE_ALLOC): Remove.
5361 (transitions_new, errs_new, reductions_new, state_new): Use malloc
5362 rather than calloc, and use offsetof to avoid allocating slightly
5363 too much storage.
5364 (state_new): Initialize all members.
5365
5366 * src/state.c (state_hash): Use unsigned accumulator, not signed.
5367
5368 * src/symtab.c (symbol_free): Remove; unused.
5369 (symbol_get): Remove cast in lhs of assignment.
5370 (symbols_do): Now static. Accept generic arguments, not
5371 hashing-related ones.
5372
5373 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
5374 (symbol_processor): Remove.
5375 (symbols_do): Remove decl; now static.
5376
5377 * src/system.h (alloca): Remove; decl no longer needed.
5378 (<stddef.h>): Include, for offsetof.
5379 (<inttypes.>, <stdint.h>): Include if available.
5380 (uintptr_t): New type, if system lacks it.
5381 (CALLOC, MALLOC, REALLOC): New macros.
5382 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
5383 new macros.
5384
5385 * src/tables.c (table_size): Now int, to pacify GCC.
5386 (table_grow, table_ninf_remap): Use signed table size.
5387 (save_row): Don't bother initializing locals when not needed.
5388 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
5389 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
5390
5391 * src/vcg.h: Correct misspellings.
5392
5393 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
5394
5395
5396 * src/getargs.c (getargs): Don't assume EOF == -1.
5397
5398 2002-12-09 Paul Eggert <eggert@twinsun.com>
5399
5400 Change identifier spellings to avoid collisions with names
5401 that are reserved by POSIX.
5402
5403 Don't use names ending in _t, since POSIX reserves them.
5404 For consistency, remove _e and _s endings -- they're weren't
5405 needed to remove ambiguity. All uses changed.
5406 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
5407 turn was just renamed from struniq_t.
5408 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
5409 which in turn was just renamed from struniq_processor_t.
5410 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
5411 in turn was renamed from hash_compare_struniq_t.
5412 * src/LR0.c (struct state_list): Renamed from struct state_list_s.
5413 (state_list): Renamed from state_list_t.
5414 * src/assoc.h (assoc): Renamed from assoc_t.

5422 (rule_number): Renamed from rule_number_t.
5423 (struct rule_s): Remove the "rule_s" part; not used.
5424 (rule): Renamed from rule_t.
5425 (rule_filter): Renamed from rule_filter_t.
5426 * src/lalr.c (struct goto_list): Renamed from struct goto_list_s.
5427 (goto_list): Renamed from goto_list_t.

5480 * tests/input.at (Torturing the Scanner): Rename value_t -> value,
5481 value_t_as_yystype -> value_as_yystype.
5482
5483 Don't include <errno.h> in the mainstream code, since it
5484 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
5485 * lib/get-errno.c, lib/get-errno.h: New files.
5486 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
5487 get-errno.c.
5488 * src/files.c (xfopen, xfclose): Use get_errno instead of errno.
5489 * src/output.c (output_skeleton): Likewise.
5490 * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno
5491 instead of errno.

5496 (TAB_EXT): Renamed from EXT_TAB.
5497 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
5498
5499 Avoid str[a-z]*, since <string.h> reserves that name space.
5500 Change all instances of "struniq" in names to "uniqstr", and
5501 likewise for "STRUNIQ" and "UNIQSTR".
5502 * src/uniqstr.c: Renamed from src/struniq.c.
5503 * src/uniqstr.h: Renamed from src/struniq.h.
5504 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

5514 (G_LONG_STRAIGHT_PHASE): Renamed from G_STRAIGHT_PHASE.
5515 (N_EXPAND): Renamed from N_STRETCH.
5516
5517 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
5518 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
5519 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):

5526 (BASE_MINIMUM): Renamed from BASE_MIN.
5527 (ACTION_MAX): Remove; unused.
5528 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
5529 Unnecessary casts removed from above defines.
5530
5531
5532 Fix misspelling in names.
5533 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
5534 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
5535 G_NODE_ALIGNEMENT.

5539 for consistency with other names.
5540 * lib/timevar.h (timevar_report): New decl.
5541 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
5542
5543
5544 Sort include-file uses.
5545
5546 Reorder all include files under src to be in the order "system.h".
5547 then the ../lib include files in angle brackets (alphabetized),
5548 then the . include files in double-quotes (alphabetized). Fix
5549 dependency breakages encountered in this process, as follows:
5550 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
5551 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
5552 * src/state.h: Include "symtab.h".
5553
5554 2002-12-08 Paul Eggert <eggert@twinsun.com>
5555
5556 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
5557 since this causes problems when __file__ contains character
5558 sequences like "@" that are treated specially by src/scan-skel.l.
5559 Instead, just use the file's basename. This fixes the bug
5560 reported by Martin Mokrejs in
5561 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
5562
5563 2002-12-06 Paul Eggert <eggert@twinsun.com>
5564
5565 Add support for rules that do not have trailing semicolons, as
5566 POSIX requires. Improve the quality of locations in Bison
5567 diagnostics.
5568
5569 * src/location.c: Include <quotearg.h>.
5570 (empty_location): Now const.
5571 (location_print): New function. Follow the recommendation of the
5572 GNU Coding Standards for locations that span file boundaries.
5573 * src/location.h: Do not include <quotearg.h>; no longer needed.
5574 (boundary): New type.
5575 (location_t): Use it. This allows locations to span file boundaries.
5576 All member uses changed: file -> start.file or end.file (as needed),
5577 first_line -> start.line, first_column -> start.column,
5578 last_line -> end.line, last_column -> end.column.
5579 (equal_boundaries): New function.
5580 (LOCATION_RESET, LOCATION_STEP): Remove.
5581 (LOCATION_PRINT): Remove. All callers changed to use location_print.
5582 (empty_location): Now const.
5583 (location_print): New decl.
5584 * src/parse-gram.y (lloc_default): New function, which handles
5585 empty locations more accurately.
5586 (YYLLOC_DEFAULT): Use it.
5587 (%token COLON): Remove.
5588 (%token ID_COLON): New token.
5589 (rules): Use it.
5590 (declarations, rules): Remove trailing semicolon.
5591 (declaration, rules_or_grammar_declaration):
5592 Allow empty (";") declaration.
5593 (symbol_def): Remove empty actions; no longer needed.
5594 (rules_or_grammar_declaration): Remove trailing semicolon.
5595 (semi_colon.opt): Remove.
5596 * src/reader.h: Include location.h.
5597 (scanner_cursor): New decl.
5598 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
5599 rolling our own.
5600 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
5601 of *loc.
5602 (STEP): Remove. No longer needed, now that adjust_location does
5603 the work. All uses removed.
5604 (scanner_cursor): New var.
5605 (adjust_location): Renamed from extend_location. It now sets
5606 *loc and adjusts the scanner cursor. All uses changed.
5607 Don't bother testing for CR.
5608 (handle_syncline): Remove location arg; now updates scanner cursor.
5609 All callers changed.
5610 (unexpected_end_of_file): Now accepts start boundary of token or
5611 comment, not location. All callers changed. Update scanner cursor,
5612 not the location.
5613 (SC_AFTER_IDENTIFIER): New state.
5614 (context_state): Renamed from c_context. All uses changed.
5615 (id_loc, code_start, token_start): New local vars.
5616 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
5617 processing of Yacc white space and equivalents here.
5618 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
5619 instead of returning ID immediately, since we need to search for
5620 a subsequent colon.
5621 (<INITIAL>"'", "\""): Save token_start.
5622 (<INITIAL>"%{", "{", "%%"): Save code_start.
5623 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
5624 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
5625 BEGIN context_state at end, not INITIAL.
5626 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
5627 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
5628 Return correct token start.
5629 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
5630 the start of a character, string or multiline comment is found.
5631 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
5632 Reduction): Adjust reported locations to match the more-precise
5633 results now expected.
5634 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
5635 * tests/reduce.at (Useless Rules, Reduced Automaton,
5636 Underivable Rules): Likewise.
5637 * tests/regression.at (Invalid inputs): No longer `expecting ";"
5638 or "|"' now that so many other tokens are allowed by the new grammar.
5639
5640 * src/complain.h (current_file): Remove duplicate decl;
5641 current_file is now owned by files.h.
5642 * src/complain.c, src/scan-gram.l: Include files.h.
5643
5644 2002-12-06 Paul Eggert <eggert@twinsun.com>
5645
5646 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
5647 promotes to int; it might be unsigned int.
5648 * data/yacc.c (yy_reduce_print): Likewise.
5649
5650 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
5651 be #defined in the prologue, not in the Bison declarations.
5652 This fixes Debian Bug 102878, reported by Shaul Karl.
5653
5654 2002-12-02 Paul Eggert <eggert@twinsun.com>
5655
5656 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
5657 * lib/strtoul.c: New file, from gnulib.
5658 This fixes a porting bug reported by Peter Klein in
5659 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
5660
5661 2002-11-30 Paul Eggert <eggert@twinsun.com>
5662
5663 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
5664 and put only a forward declaration in the prologue. This is for
5665 consistency with the other scanner helper functions.
5666
5667 Type clashes now generate warnings, not errors, since it
5668 appears that POSIX may allow some grammars with type clashes.
5669 * src/reader.c (grammar_current_rule_check): Warn about
5670 type clashes instead of complaining.
5671 * tests/input.at (Type Clashes): Expect warnings, not complaints.
5672
5673 Add Yacc library, since POSIX requires it.
5674 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
5675 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
5676 * lib/main.c, lib/yyerror.c: New files.
5677
5678 gram_error can be static; it need not be extern.
5679 * src/reader.h (gram_error): Remove decl.
5680 * src/parse-gram.y (gram_error): Now static. Add static decl.
5681 (print_token_value): Omit parameter names from forward decl,
5682 for consistency.
5683
5684 2002-11-29 Paul Eggert <eggert@twinsun.com>
5685
5686 * doc/bison.texinfo: Emphasize that yylex and yyerror must
5687 be declared before being used. E.g., one should typically
5688 declare them in the prologue. Use GNU coding style in examples.
5689 Put "const" consistently after the type it modifies. Mention
5690 that C99 supports "inline". Mention that yyerror traditionally
5691 returns "int".
5692
5693 %parse-param and %lex-param now take just one argument, the
5694 declaration; the argument name is deduced from the declaration.
5695
5696 * doc/bison.texinfo (Parser Function, Pure Calling, Error
5697 Reporting, Table of Symbols): Document this.
5698 * src/parse-gram.y (add_param): New function.
5699 (COMMA): Remove.
5700 (declaration): Implement new rule for %parse-param and %lex-param.
5701 * src/scan-gram.l: "," now elicits a warning, rather than being
5702 a token; this is more compatible with byacc.
5703 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
5704
5705 2002-11-27 Paul Eggert <eggert@twinsun.com>
5706
5707 Rename identifiers to avoid real and potential collisions.
5708
5709 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
5710 to avoid collision with lex macro described by Bruce Lilly in
5711 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
5712 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
5713 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
5714 * src/parse-gram.y (print_token_value): Renamed from yyprint.
5715 All uses changed.
5716 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
5717 The name "yycontrol" violates the name space rules, and this stuff
5718 wasn't being used anyway.
5719 (input): Remove action; this stuff wasn't being used.
5720 (gram_error): Rename local variable yylloc -> loc.
5721 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
5722 (YY_DECL): Don't use "yy" at start of local variables.
5723 All uses changed, e.g., yylloc -> loc.
5724 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
5725 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
5726 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
5727 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
5728
5729 * src/parse-gram.y (gram_error): loc is now const *.
5730 * src/reader.h (gram_error): Likewise.
5731
5732 2002-11-24 Paul Eggert <eggert@twinsun.com>
5733
5734 Version 1.75c.
5735
5736 * tests/actions.at (Actions after errors): Use an output format
5737 more similar to that of the Printers and Destructors test.
5738 Test the position of the ';' token too.
5739 (Printers and Destructors): Likewise.
5740 (Printers and Destructors: %glr-parser): Remove for now, to avoid
5741 unnecessarily alarming people when the test fails.
5742
5743 * data/yacc.c (yyerrlab1): Move this label down, so that the
5744 parser does not discard the lookahead token if the user code
5745 invokes YYERROR. This change is required for POSIX conformance.
5746
5747 * lib/error.c: Sync with gnulib.
5748
5749 2002-11-22 Paul Eggert <eggert@twinsun.com>
5750
5751 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
5752 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
5753 * lib/xmalloc.c: Likewise.
5754
5755 2002-11-20 Paul Eggert <eggert@twinsun.com>
5756
5757 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
5758
5759 2002-11-20 Paul Eggert <eggert@twinsun.com>
5760
5761 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
5762 should use `if (! x) abort ();' rather than `assert (x);', and
5763 anyway it's one less thing to worry about configuring.
5764
5765 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
5766 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
5767 and replace all instances of assert with abort.
5768 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
5769 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
5770
5771 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
5772 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
5773 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
5774 hash_find_entry, hash_rehash, hash_insert): Likewise.
5775 * src/conflicts.c (resolve_sr_conflict): Likewise.
5776 * src/lalr.c (set_goto_map, map_goto): Likewise.
5777 * src/nullable.c (nullable_compute): Likewise.
5778 * src/output.c (prepare_rules, token_definitions_output): Likewise.
5779 * src/reader.c (packgram, reader): Likewise.
5780 * src/state.c (state_new, state_free, state_transitions_set,
5781 state_reduction_find): Likewise.
5782 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
5783 symbol_pack): Likewise.
5784 * src/tables.c (conflict_row, pack_vector): Likewise.
5785 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
5786 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
5787 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
5788 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
5789
5790 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
5791 (ARGMATCH_CONSTRAINT): New macro.
5792 (ARGMATCH_ASSERT): Use it.
5793
5794 * src/system.h (verify): New macro.
5795 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
5796 rather than assert.
5797 * src/tables.c (tables_generate): Likewise.
5798
5799 * src/struniq.c (struniq_assert): Now returns void, and aborts
5800 if the assertion is false.
5801 (struniq_assert_p): Remove.
5802 * src/struniq.h: Likewise.
5803
5804 2002-11-18 Paul Eggert <eggert@twinsun.com>
5805
5806 * data/glr.c (yygetLRActions): Replace `yyindex' with
5807 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
5808 This fixes the regression with Sun ONE Studio 7 cc that I reported in
5809 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
5810
5811 2002-11-18 Akim Demaille <akim@epita.fr>
5812
5813 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
5814 space.
5815 From Tim Van Holder.
5816
5817 2002-11-17 Paul Eggert <eggert@twinsun.com>
5818
5819 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
5820 to "SyntaxError" for consistency with my 2002-11-15 change.
5821
5822 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
5823 not define to {}, since this breaks the common use of `YYDPRINTF
5824 ((...));' if a single statement is desired (e.g. before `else').
5825 Work around GCC warnings by surrounding corresponding calls with
5826 {} if needed.
5827 (yyhasResolvedValue): Remove unused function.
5828 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
5829 loop body.
5830 (yyreportSyntaxError): Renamed from yyreportParseError.
5831 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
5832 All uses changed.
5833 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
5834 extern when possible. Remove unused initializations.
5835
5836 2002-11-16 Akim Demaille <akim@epita.fr>
5837
5838 Augment the similarity between GLR and LALR traces.
5839
5840 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
5841 (YY_REDUCE_PRINT): New.
5842 (yyparse): Use them.
5843 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
5844 YYDPRINT here.
5845 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
5846 state reached after the reduction/recovery, since...
5847 (yyparse, yyprocessOneStack): Report the state we are entering in.
5848
5849 2002-11-16 Akim Demaille <akim@epita.fr>
5850
5851 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
5852 Add support for --trace=skeleton.
5853 * src/scan-skel.l: %option debug.
5854 Scan strings of non-@ or \n instead of character by character.
5855 (scan_skel): Handle trace_skeleton.
5856 (QPUTS): New.
5857 (@output_parser_name@, @output_header_name@): ``Restore'' their
5858 support (used to be M4 macros).
5859 * data/yacc.c: Quote larger chunks, a la glr.c.
5860 * data/lalr1.cc: Likewise.
5861 The header guards are no longer available, so use some other
5862 string than `YYLSP_NEEDED'.
5863
5864 2002-11-16 Akim Demaille <akim@epita.fr>
5865
5866 Make the ``Printers and Destructors'' test more verbose, taking
5867 `yacc.c''s behavior as (possibly wrong) reference.
5868
5869 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
5870 instead of fprint on stdout.
5871 Set and report the last_line of the symbols.
5872 Consistently display values and locations.
5873
5874 2002-11-16 Paul Eggert <eggert@twinsun.com>
5875
5876 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
5877
5878 2002-11-15 Paul Eggert <eggert@twinsun.com>
5879
5880 * tests/actions.at (Actions after errors): New test case.

5884 tests/action.at, tests/calc.at, tests/conflicts.at,
5885 tests/cxx-type.at, tests/regression.at:
5886 "parse error" -> "syntax error" for POSIX compatibility.
5887 "parsing stack overflow..." -> "parser stack overflow" so
5888 that code matches Bison documentation.
5889
5890 2002-11-15 Akim Demaille <akim@epita.fr>
5891
5892 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
5893 take two BRACED_CODE, not two string_content.
5894 Free the scanner's obstack when we are done.
5895 (code_content): New.
5896 * tests/calc.at: Adjust.
5897 * doc/bison.texinfo: Adjust.
5898 Also, make sure to include the `,' for these declarations.
5899
5900 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
5901
5902 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
5903 definition; avoids potential autoreconf problems.
5904
5905 2002-11-15 Akim Demaille <akim@epita.fr>
5906
5907 Always check the value returned by yyparse.
5908
5909 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
5910 returned by yyparse.
5911 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
5912 Adjust calls.
5913 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
5914 returned by yyparse.
5915
5916 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
5917
5918 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
5919 on input.at test.
5920
5921 2002-11-14 Paul Eggert <eggert@twinsun.com>
5922
5923 * src/output.c (output_skeleton): Call xfopen instead of

5926 Fix bugs reported by Nelson H. F. Beebe in
5927 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
5928
5929 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
5930 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
5931 Group compiler. Instead, use "$CC -E bar.c". Include the .h
5932 file twice in the grammar, as an extra check.
5933
5934 * tests/input.at (Torturing the Scanner): Surround the
5935 backslash-newline tests with "#if 0", to make it less likely that
5936 we'll run into compiler bugs. Bring back solitary \ inside
5937 comment, but add a closing comment to work around HP C bug. Don't
5938 test backslash-newline in C character constant.
5939
5940 2002-11-14 Akim Demaille <akim@epita.fr>
5941
5942 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
5943 status of the compiler.
5944 Calling `exit 1' is no longer needed.
5945 Reported by Nelson H. F. Beebe.
5946
5947 2002-11-14 Akim Demaille <akim@epita.fr>
5948

5950 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
5951 New.
5952 * tests/actions.at, tests/calc.at, tests/conflicts.at,
5953 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
5954 * tests/regression.at, tests/torture.at: Use them for all the
5955 grammars that are to be compiled.
5956 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
5957 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
5958 * doc/bison.texinfo (GLR Parsers): Document `inline'.
5959
5960 2002-11-14 Akim Demaille <akim@epita.fr>
5961
5962 * doc/bison.texinfo: Various formatting changes (alignments in
5963 samples, additional @group/@end group, GCS in samples.
5964 Use @deffn instead of simple @table to define the directives,
5965 macros, variables etc.
5966
5967 2002-11-13 Paul Eggert <eggert@twinsun.com>
5968
5969 Fix some bugs reported by Albert Chin-A-Young in
5970 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
5971
5972 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
5973 -o c"; the HP C compiler chatters during compilation.
5974 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
5975 * tests/headers.at (export YYLTYPE): Likewise.
5976
5977 * tests/input.at (Torturing the Scanner): Remove lines containing
5978 solitary backslashes, as they tickle a bug in the HP C compiler.
5979
5980 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
5981 comments, since they're not portable. Use GNU coding style.
5982
5983 2002-11-13 Akim Demaille <akim@epita.fr>
5984
5985 * data/yacc.c: Leave bigger chunks of quoted text.
5986 (YYDSYMPRINTF): New.
5987 Use it to report symbol activities.
5988 * data/glr.c (YYDSYMPRINTF): New.
5989 Use it.
5990
5991 2002-11-12 Paul Eggert <eggert@twinsun.com>

5994
5995 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
5996 (yyglrReduce): Return yyok, not 0.
5997 This should avoid the enumerated-type warnings reported
5998 by Nelson H. F. Beebe in
5999 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
6000
6001 * lib/bbitset.h (BITSET_INLINE): Remove.
6002 * lib/bitset.h [! BITSET_INLINE]: Remove.
6003 (bitset_set, bitset_reset, bitset_test): Rename local vars
6004 to avoid shadowing warnings by GCC.
6005
6006 * data/glr.c (inline): Remove #define. It's the user's
6007 responsibility to #define it away, just like 'const'.
6008 This fixes one of the bugs reported by Nelson H. F. Beebe in
6009 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
6010
6011 * Makefile.maint (po-check): Scan .l and .y files instead of the
6012 .c and the .h files that they generate. This fixes the bug
6013 reported by Tim Van Holder in:
6014 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
6015 Look for N_ as well as for _. Try to avoid matching #define for
6016 N_ and _.
6017 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
6018 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
6019 * src/scan-gram.l: Revamp regular expressions so that " and '
6020 do not confuse xgettext.
6021
6022 * src/struniq.h (struniq_new): Do not declare the return type
6023 to be 'const'; this violates the C standard.
6024 * src/struniq.c (struniq_new): Likewise.
6025
6026 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
6027
6028 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
6029 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
6030 linker.
6031
6032 2002-11-12 Akim Demaille <akim@epita.fr>
6033
6034 * Makefile.maint: Sync with Autoconf:
6035 (local_updates): New.

6044 locations.
6045
6046 2002-11-12 Akim Demaille <akim@epita.fr>
6047
6048 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
6049 not yyvalue.
6050
6051 2002-11-12 Akim Demaille <akim@epita.fr>
6052
6053 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
6054 Use it to test the GLR parser.
6055
6056 2002-11-12 Akim Demaille <akim@epita.fr>
6057
6058 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
6059 defines it.
6060 * data/glr.c (yystos): New.
6061 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
6062 (YYDSYMPRINT): New.

6064 (yyrecoverParseError): Free verbosely the discarded symbols.
6065 * data/yacc.c (yysymprint): Remove, rather...
6066 (b4_yysymprint_generate): invoke.
6067 * data/c.m4 (b4_yysymprint_generate): New.
6068 Accept pointers as arguments, as opposed to the version from
6069 yacc.c.
6070 (b4_yydestruct_generate): Likewise.
6071 * tests/cations.at (Printers and Destructors): Use Bison directives
6072 instead of CPP macros.
6073 Don't rely on internal details.
6074
6075 2002-11-12 Akim Demaille <akim@epita.fr>
6076
6077 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
6078 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
6079 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
6080 it against YYEMPTY and so forth), work on yytoken (i.e., set
6081 it to YYEMPTY etc.).
6082 (yydestruct): Replace with a b4_yydestruct_generate invocation.
6083 (b4_symbol_actions): Remove.
6084 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
6085 for 0, end-of-input.
6086
6087 2002-11-12 Akim Demaille <akim@epita.fr>
6088
6089 * doc/bison.texinfo (Destructor Decl): New.
6090
6091 2002-11-12 Akim Demaille <akim@epita.fr>
6092
6093 * src/tables.c (tables_generate): Use free for pointers that
6094 cannot be NULL, not XFREE.
6095 (pack_vector): Use assert, not fatal, for bound violations.
6096 * src/state.c (state_new): Likewise.
6097 * src/reader.c (reader): Likewise.
6098 * src/lalr.c (set_goto_map): Likewise.
6099 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
6100 the file name.
6101
6102 2002-11-12 Akim Demaille <akim@epita.fr>
6103
6104 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
6105 Restore.
6106 * src/scan-gram.l (last_string): Is global to the file, not to
6107 yylex.
6108 * src/parse-gram.y (input): Don't append the epilogue here,
6109 (epilogue.opt): do it here, and free the scanner's obstack.
6110 * src/reader.c (epilogue_set): Rename as...
6111 (epilogue_augment): this.
6112 * data/c.m4 (b4_epilogue): Defaults to empty.
6113
6114 2002-11-12 Akim Demaille <akim@epita.fr>
6115
6116 * src/getargs.c (long_options): Remove duplicates.

6125 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
6126

6128
6129 * src/symtab.h (symbol_t): The tag member is a struniq.
6130 (symbol_type_set): Adjust.
6131 * src/symtab.c (symbol_new): Takes a struniq.
6132 (symbol_free): Don't free the tag member.
6133 (hash_compare_symbol_t, hash_symbol_t): Rename as...

6154 file names.
6155 Don't free the input file name.
6156
6157 2002-11-12 Akim Demaille <akim@epita.fr>
6158

6170 2002-11-11 Paul Eggert <eggert@twinsun.com>
6171
6172 Revamp to fix many (but not all) of the C- and M4-related quoting
6173 problems. Among other things, this fixes the Bison bug reported
6174 by Jan Hubicka when processing the Bash grammar; see:
6175 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
6176
6177 Use new @ escapes consistently. Represent brackets with @{ and @}
6178 rather than @<:@ and @:>@, since this works a bit better with dumb
6179 editors like vi. Represent @ with @@, since @ is now consistently
6180 an escape. Use @oline@ and @ofile@ rather than __oline__ and
6181 __ofile__, to avoid unexpected expansions. Similarly, use @output
6182 rather than #output.
6183
6184 * data/c.m4 (b4_copyright): Omit file name from comment, since
6185 the file name could contain "*/".
6186 (b4_synclines_flag): Don't quote the 2nd argument; it should already
6187 be quoted. All uses changed.
6188
6189 * data/glr.c: Use new @ escapes consistently.
6190 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
6191 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
6192 Remove, since they couldn't handle arbitrary characters in file
6193 names.
6194 * data/lalr1.cc: Likewise.
6195 * data/yacc.c: Likewise.
6196
6197 * src/files.c (output_infix): Remove; all uses removed.
6198 * src/files.h: Likewise.
6199
6200 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
6201 mishandled funny characters in file names, and anyway it isn't
6202 needed any more.
6203 * data/yacc.c: Likewise.
6204 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
6205
6206 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
6207 * data/yacc.c: Likewise.
6208
6209 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
6210 strings now.
6211 (muscle_init): Quote filename as a C string.
6212 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
6213 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
6214 * src/output.c (escaped_file_name_output): New function.
6215 (prepare_symbols): Quote tokens for M4.
6216 (prepare): Don't insert output_infix, output_prefix,
6217 output_parser_name, output_header_name; this is now down by scan-skel.
6218 Insert skeleton as a C string.
6219
6220 * src/output.c (user_actions_output, symbol_destructors_output,
6221 symbol_printers_output): Quote filenames for C and M4.
6222 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6223
6224 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
6225 escapes other than \\ and \'; this simplifies the code.
6226 (<SC_STRING>): Likewise, for \\ and \".
6227 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
6228 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
6229 Use new escapes @{ and @} for [ and ].
6230
6231 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
6232 them with auto vars.
6233 Switch to new escape scheme, where @ is the escape character uniformly.
6234 Abort if a stray escape character is found. Avoid unbounded input
6235 buffer when parsing non-escaped text.
6236
6237 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
6238 __oline__, #output, $@, and @{ do not have unintended meanings.
6239
6240 2002-11-09 Paul Eggert <eggert@twinsun.com>
6241
6242 Fix the test failure due to GCC warnings described in
6243 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
6244 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
6245 evaluate to 0 if it's impossible for NINF to be in the respective
6246 table.
6247 (yygetLRActions, yyrecoverParseError): Use them.
6248
6249 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
6250 counted in the token inserted at end of file. Now takes
6251 location_t *, not location_t, so that the location can be
6252 adjusted. All uses changed.
6253
6254 * tests/regression.at (Invalid inputs): Adjust wording in
6255 diagnostic to match the new behavior.
6256
6257 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
6258 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
6259 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
6260 abort ();'. This reduces the runtime of the "Many lookaheads"
6261 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
6262 GCC 3.2.
6263
6264 2002-11-07 Paul Eggert <eggert@twinsun.com>
6265
6266 * src/parse-gram.y (CHARACTER): Remove unused token.
6267 All uses removed.
6268
6269 * src/scan-gram.l: Remove stack option. We no longer use the
6270 stack, since the stack was never deeper than 1; instead, use the
6271 new auto var c_context to record the stacked value.
6272
6273 Remove nounput option. At an unexpected end of file, we now unput
6274 the minimal input necessary to end cleanly; this simplifies the
6275 code.
6276
6277 Avoid unbounded token sizes where this is easy.
6278
6279 (unexpected_end_of_file): New function.
6280 Use it to systematize the error message on unexpected EOF.
6281 (last-string): Now auto, not static.
6282 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
6283 (scanner_last_string_free): Remove; not used.
6284 (percent_percent_count): Move decl to just before use.
6285 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
6286 not the (never otherwised-used) CHARACTER.
6287
6288 2002-11-07 Akim Demaille <akim@epita.fr>
6289
6290 Let yyerror always receive the msg as last argument, so that
6291 yyerror can be variadic.
6292
6293 * data/yacc.c (b4_yyerror_args): New.
6294 Use it when calling yyerror.
6295 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
6296 Use it when calling yyerror.
6297 * doc/bison.texinfo (Error Reporting): Adjust.
6298 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
6299 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
6300
6301 2002-11-06 Akim Demaille <akim@epita.fr>
6302
6303 #line should have quoted strings.
6304 Ideally, this should be done by m4_quotearg.
6305
6306 * src/scan-skel.l: Include quotearg.h.
6307 Quote __ofile__.
6308 * src/output.c (symbol_printers_output)
6309 (symbol_destructors_output): Quote the file name.
6310
6311 2002-11-06 Akim Demaille <akim@epita.fr>
6312
6313 * tests/regression.at (Invalid inputs): Adjust to the recent
6314 messages.
6315
6316 2002-11-06 Akim Demaille <akim@epita.fr>
6317
6318 Restore --no-lines.
6319 Reported by Jim Kent.
6320
6321 * data/c.m4 (b4_syncline): New.
6322 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
6323 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
6324 * src/output.c (user_actions_output): Likewise.
6325 (prepare): Define 'b4_synclines_flag'.
6326 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
6327
6328 2002-11-06 Akim Demaille <akim@epita.fr>
6329
6330 * src/main.c (main): Free `infile'.
6331 * src/scan-gram.l (handle_syncline): New.
6332 Recognize `#line'.
6333 * src/output.c (user_actions_output, symbol_destructors_output)
6334 (symbol_printers_output): Use the location's file name, not
6335 infile.
6336 * src/reader.c (prologue_augment, epilogue_set): Likewise.
6337
6338 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6339
6340 * src/tables.c (matching_state): Don't allow states to match if
6341 either has GLR conflict entries.
6342
6343 2002-11-05 Paul Eggert <eggert@twinsun.com>
6344
6345 * src/scan-gram.l: Use more accurate diagnostics, e.g.
6346 "integer out of range" rather than "invalid value".
6347 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
6348 accordingly.
6349
6350 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
6351 Also, remove one static variable in the scanner.
6352
6353 * src/scan-gram.l (braces_level): Now auto, not static.
6354 Initialize to zero if the compiler is being picky.
6355 (INITIAL): Clear braces_level instead of incrementing it.
6356 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
6357 as POSIX 1003.1-2001 requires.
6358 * src/system.h (IF_LINT): New macro, taken from coreutils.
6359 * configure.ac: Define "lint" if --enable-gcc-warnings.
6360
6361 2002-11-05 Akim Demaille <akim@epita.fr>
6362
6363 * src/scan-gram.l: When it starts with `%', complain about the
6364 whole directive, not just that `invalid character: %'.
6365
6366 2002-11-04 Akim Demaille <akim@epita.fr>
6367
6368 * Makefile.maint: Update from Autoconf.
6369 (update, cvs-update, po-update, do-po-update): New.
6370
6371 2002-11-04 Akim Demaille <akim@epita.fr>
6372
6373 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
6374 and yyerror.
6375 Have yyerror `use' its arguments.
6376 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
6377 returns true when location & yacc & pure & parse-param.
6378 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
6379
6380 2002-11-04 Akim Demaille <akim@epita.fr>
6381
6382 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
6383 clashes.
6384 * src/scan-gram.l: Use [\'] instead of ['] to pacify
6385 font-lock-mode.
6386 Use complain_at.
6387 Use quote, not quote_n since LOCATION_PRINT no longer uses the
6388 slot 0.
6389
6390 2002-11-03 Paul Eggert <eggert@twinsun.com>
6391
6392 * src/reader.c (get_merge_function, grammar_current_rule_check):
6393 Use consistent diagnostics for reporting type name clashes.
6394 Quote the types with <>, for consistency with Yacc.
6395 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
6396
6397 2002-11-03 Akim Demaille <akim@epita.fr>

6400 New.
6401 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
6402 (b4_parse_param): Remove.
6403 Use b4_identification.
6404 Propagate b4_pure_args where needed to pass them to yyerror.
6405 * data/glr.m4 (b4_parse_param): Remove.
6406 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
6407 (b4_lpure_formals): New.
6408 Use b4_identification.
6409 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
6410 b4_user_formals and b4_user_args.
6411 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
6412 (yyreportAmbiguity): When using a pure parser, also need
6413 the location, and the parse-params.
6414 Adjust callers.
6415 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
6416 When using a pure parser, also need the parse-params.
6417 Adjust callers.
6418 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
6419 (%pure-parser + %parse-param) LALR and GLR parsers.
6420 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
6421 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
6422 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
6423 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
6424 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
6425 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
6426 * doc/bison.texinfo: Untabify the whole file.
6427 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
6428 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
6429 (Error Reporting): Adjust to these new directives.
6430 Document %error-verbose, deprecate YYERROR_VERBOSE.
6431
6432 2002-11-03 Akim Demaille <akim@epita.fr>
6433
6434 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
6435 AT_CHECK_CALC_GLR invocations to use % directives, instead of
6436 command line options.
6437 * tests/cxx-type.at: Formatting changes.
6438
6439 2002-11-03 Paul Eggert <eggert@twinsun.com>
6440
6441 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
6442 to count columns correctly, and to check for invalid inputs.
6443
6444 Use mbsnwidth to count columns correctly. Account for tabs, too.
6445 Include mbswidth.h.
6446 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
6447 (extend_location): New function.
6448 (YY_LINES): Remove.
6449
6450 Handle CRLF in C code rather than in Lex code.
6451 (YY_INPUT): New macro.
6452 (no_cr_read): New function.
6453
6454 Scan UCNs, even though we don't fully handle them yet.
6455 (convert_ucn_to_byte): New function.
6456
6457 Handle backslash-newline correctly in C code.
6458 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
6459 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
6460 all uses changed.
6461 (tag, splice): New EREs. Do not allow NUL or newline in tags.
6462 Use {splice} wherever C allows backslash-newline.
6463 YY_STEP after space, newline, vertical-tab.
6464 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
6465
6466 (letter, id): Don't assume ASCII; e.g., spell out a-z.
6467
6468 ({int}, handle_action_dollar, handle_action_at): Check for integer
6469 overflow.
6470
6471 (YY_STEP): Omit trailing semicolon, so that it's more like C.
6472
6473 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
6474 as well as \000. Check for UCHAR_MAX, not 255.
6475 Allow \x with an arbitrary positive number of digits, as in C.
6476 Check for overflow here.
6477 Allow \? and UCNs, for compatibility with C.
6478
6479 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
6480 with quote slot used by complain_at.
6481
6482 * tests/input.at: Add tests for backslash-newline, m4 quotes
6483 in symbols, long literals, and funny escapes in strings.
6484
6485 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
6486 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
6487 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
6488 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
6489 * m4/mbswidth.m4: New file, from GNU coreutils.
6490
6491 * doc/bison.texinfo (Grammar Outline): Document // comments.
6492 (Symbols): Document that trigraphs have no special meaning in Bison,
6493 nor is backslash-newline allowed.
6494 (Actions): Document that trigraphs have no special meaning.
6495
6496 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
6497 no longer used.
6498
6499 2002-11-02 Paul Eggert <eggert@twinsun.com>
6500
6501 * src/reader.c: Don't include quote.h; not needed.
6502 (get_merge_function): Reword warning to be consistent with
6503 type clash diagnostic in grammar_current_rule_check.
6504
6505 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
6506 bug in trigraph handling.
6507
6508 * src/output.c (prepare_symbols): When printing token names,
6509 escape "[" as "@<:@" and likewise for "]".
6510
6511 * src/system.h (errno): Remove declaration, as we are now
6512 assuming C89 or better, and C89 guarantees errno.
6513
6514 2002-10-30 Paul Eggert <eggert@twinsun.com>
6515
6516 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
6517 Check for close failures.
6518 * src/files.h (xfclose): Return void, not int, since it always
6519 returned zero.
6520 * src/files.c (xfclose): Likewise. Report I/O error if ferror
6521 indicates one.
6522 * src/output.c (output_skeleton): Use xfclose rather than fclose
6523 and ferror. xfclose now checks ferror.
6524
6525 * data/glr.c (YYLEFTMOST_STATE): Remove.
6526 (yyreportTree): Use a stack-based leftmost state. This avoids
6527 our continuing battles with bogus warnings about initializers.
6528
6529 2002-10-30 Akim Demaille <akim@epita.fr>
6530
6531 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
6532 #if.
6533
6534 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
6535
6536 * tests/glr-regr1.at: New test for reported regressions.
6537 * tests/testsuite.at: Add glr-regr1.at test.
6538 * tests/Makefile.am: Add glr-regr1.at test.
6539
6540 2002-10-24 Paul Eggert <eggert@twinsun.com>
6541
6542 Version 1.75a.
6543
6544 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
6545 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
6546 we use malloc. Don't assume 'A' through 'Z' are contiguous.
6547 Don't assume strdup exists; POSIX says its an XSI extension.
6548 Check for buffer overflow on input.
6549
6550 2002-10-24 Akim Demaille <akim@epita.fr>
6551
6552 * src/output.c (output_skeleton): Don't disable M4sugar comments
6553 too soon: it results in comments being expanded.
6554 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
6555 first output.
6556
6557 2002-10-24 Akim Demaille <akim@epita.fr>
6558
6559 * data/yacc.c (m4_int_type): New.
6560 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
6561 char' as only yacc.c wants K&R portability.
6562 * data/glr.c (yysigned_char): Remove.
6563 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
6564 Reported by Quoc Peyrot.
6565
6566 2002-10-23 Paul Eggert <eggert@twinsun.com>
6567
6568 * src/main.c (main): With --trace=time, report times even if a
6569 non-fatal error occurs. Formerly, the times were reported in some
6570 such cases but not in others.
6571 * src/reader.c (reader): Just return if a complaint has been issued,
6572 instead of exiting, so that 'main' can report times.
6573
6574 2002-10-22 Akim Demaille <akim@epita.fr>
6575
6576 * src/system.h: Include sys/types.
6577 Reported by Bert Deknuydt.
6578
6579 2002-10-23 Paul Eggert <eggert@twinsun.com>
6580
6581 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
6582 Suggested by Art Haas.
6583
6584 2002-10-22 Paul Eggert <eggert@twinsun.com>
6585
6586 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
6587 decl; not needed any more.
6588 * src/main.c (main): Use return to exit, undoing yesterday's change.
6589 The last OS that we could find where this wouldn't work is
6590 SunOS 3.5, and that's too old to worry about now.
6591
6592 * data/glr.c (struct yyltype): Define members even when not
6593 doing locations. This is more consistent with yacc.c, and it
6594 works around the following bug reports:
6595 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
6596 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
6597
6598 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
6599 @acronym consistently. Standardize on "Yacc" instead of "YACC",
6600 "Algol" instead of "ALGOL". Give a bit more history about BNF.
6601
6602 2002-10-22 Akim Demaille <akim@epita.fr>
6603
6604 * data/README: New.
6605
6606 2002-10-21 Paul Eggert <eggert@twinsun.com>
6607
6608 Be consistent about 'bool'; the old code used an enum in one
6609 module and an int in another, and this violates the C standard.
6610 * m4/stdbool.m4: New file, from coreutils 4.5.3.
6611 * configure.ac (AC_HEADER_STDBOOL): Add.
6612 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
6613 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
6614 * src/symtab.c (hash_compare_symbol_t): Likewise.
6615 * src/system.h (bool, false, true): Use a definition consistent
6616 with ../lib/hash.c. All uses changed.
6617
6618 * src/complain.c (warning_issued): Renamed from warn_message_count,
6619 so that we needn't worry about integer overflow (!).
6620 Now of type bool. All uses changed.
6621 (complaint_issued): Renamed from complain_message_count; likewise.
6622
6623 * src/main.c (main): Use exit to exit with failure.
6624
6625 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
6626 rather than 1 and 0.
6627 * src/main.c (main): Likewise.
6628 * src/getargs.c (getargs): Likewise.
6629 * src/reader.c (reader): Likewise.
6630
6631 * src/getarg.c (getargs): Remove duplicate code for
6632 "Try `bison --help'".
6633
6634 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
6635 What was that "2" for?
6636
6637 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
6638 * src/getargs.c (usage): Likewise.
6639
6640 * src/getargs.c (getargs): When there are too few operands, report
6641 the last one. When there are too many, report the first extra
6642 one. This is how diffutils does it.
6643
6644 2002-10-20 Paul Eggert <eggert@twinsun.com>
6645
6646 Remove K&R vestiges.
6647 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
6648 * src/complain.c (VA_START): Remove. Assume prototypes.
6649 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
6650 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
6651 fatal): Assume prototypes.
6652 * src/complain.h: Assume prototypes.
6653 * src/system.h (PARAMS): Remove.
6654 Include <limits.h> unconditionally, since it's guaranteeed even
6655 for a freestanding C89 compiler.
6656 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
6657 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
6658
6659 2002-10-20 Akim Demaille <akim@epita.fr>
6660
6661 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
6662 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
6663 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
6664 (yyresolveStates, yyresolveAction, yyresolveStack)
6665 (yyprocessOneStack): Use them.
6666 (yy_reduce_print): New.
6667 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
6668
6669 2002-10-20 Akim Demaille <akim@epita.fr>
6670
6671 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
6672 arguments and output `void'.
6673 (b4_c_function): Rename as...
6674 (b4_c_function_def): this.
6675 (b4_c_function_decl, b4_c_ansi_function_def)
6676 (b4_c_ansi_function_decl): New.
6677 Change the interpretation of the arguments: before `int, foo', now
6678 `int foo, foo'.
6679 * data/yacc.c (yyparse): Prototype and define thanks to these.
6680 Adjust b4_c_function_def uses.
6681 * data/glr.c (yyparse): Likewise, but ANSI only.
6682
6683 2002-10-20 Akim Demaille <akim@epita.fr>
6684
6685 * src/output.c (prepare): Move the definition of `tokens_number',
6686 `nterms_number', `undef_token_number', `user_token_number_max'
6687 to...
6688 (prepare_tokens): Here.
6689 (prepare_tokens): Rename as...
6690 (prepare_symbols): this.
6691 (prepare): Move the definition of `rules_number' to...
6692 (prepare_rules): here.
6693 (prepare): Move the definition of `last', `final_state_number',
6694 `states_number' to...
6695 (prepare_states): here.
6696 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.

6699
6700 * src/tables.h, src/tables.c, src/output.c: Comment changes.
6701
6702 2002-10-20 Akim Demaille <akim@epita.fr>
6703
6704 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
6705 * data/c.m4: here.
6706
6707 2002-10-20 Akim Demaille <akim@epita.fr>
6708
6709 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
6710 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
6711 `pair'.
6712 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
6713 `name' to...
6714 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
6715 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):

6719
6720 Do not create a temporary file, as that involves security and
6721 cleanup headaches. Instead, use a pair of pipes.
6722 Derived from a suggestion by Florian Krohm.
6723 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
6724 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
6725 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
6726 (BISON_PREREQ_SUBPIPE): Add.
6727 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
6728 Add subpipe.h, subpipe.c.
6729 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
6730 * po/POTFILES.in: Add lib/subpipe.c.
6731 * src/output.c: Include "subpipe.h".
6732 (m4_invoke): Remove decl.
6733 (scan_skel): New decl.
6734 (output_skeleton): Use pipe rather than temporary file for m4 input.
6735 Check that m4sugar.m4 is readable, to avoid deadlock.
6736 Check for pipe I/O error.
6737 * src/scan-skel.l (readpipe): Remove decl.
6738 (scan_skel): New function, to be used in place of m4_invoke.
6739 Read from stream rather than file.
6740
6741 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
6742 float, as this generates a warning on Solaris 8 + GCC 3.2 with
6743 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
6744 this generates a more-accurate value anyway.
6745
6746 * lib/timevar.c (timervar_accumulate): Rename locals to
6747 avoid confusion with similarly-named more-global.
6748 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
6749
6750 * src/output.c (prepare): Use xstrdup to convert char const *
6751 to char *, to avoid GCC warning.
6752
6753 2002-10-19 Akim Demaille <akim@epita.fr>
6754
6755 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
6756 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
6757 Use them to have `calc.y' ready for %pure-parser.
6758 * data/yacc.c (YYLEX): Pass a yylex return type to
6759 b4_c_function_call.
6760
6761 2002-10-19 Akim Demaille <akim@epita.fr>
6762
6763 Prototype support of %lex-param and %parse-param.
6764
6765 * src/parse-gram.y: Add the definition of the %lex-param and
6766 %parse-param tokens, plus their rules.
6767 Drop the `_' version of %glr-parser.
6768 Add the "," token.
6769 * src/scan-gram.l (INITIAL): Scan them.
6770 * src/muscle_tab.c: Comment changes.
6771 (muscle_insert, muscle_find): Rename `pair' as `probe'.
6772 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
6773 (muscle_entry_s): The `value' member is no longer const.
6774 Adjust all dependencies.
6775 * src/muscle_tab.c (muscle_init): Adjust: use
6776 MUSCLE_INSERT_STRING.
6777 Initialize the obstack earlier.
6778 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
6779 (muscle_pair_list_grow): New.
6780 * data/c.m4 (b4_c_function_call, b4_c_args): New.
6781 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
6782 * tests/calc.at: Use %locations, not --locations.
6783 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
6784
6785 2002-10-19 Akim Demaille <akim@epita.fr>
6786
6787 * src/getargs.c (usage): Take status as argument and exit
6788 accordingly.
6789 Report the traditional `Try ... --help' message when status != 0.
6790 (usage, version): Don't take a FILE * as arg, it is pointless.
6791 (getargs): When there is an incorrect number of arguments, make it
6792 an error, and report it GNUlically thanks to `usage ()'.
6793
6794 2002-10-18 Paul Eggert <eggert@twinsun.com>
6795
6796 * data/glr.c (yyreportParseError): Don't assume that sprintf
6797 yields the length of the printed string, as this is not true
6798 on SunOS 4.1.4. Reported by Peter Klein.
6799
6800 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
6801 * tests/conflicts.at (%nonassoc and eof): Likewise.
6802 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
6803
6804 2002-10-17 Akim Demaille <akim@epita.fr>
6805
6806 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
6807 * src/getargs.c (trace_types, trace_args): Adjust.
6808 * src/reader.c (grammar_current_rule_prec_set)
6809 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
6810 Standardize error messages.
6811 And s/@prec/%prec/!
6812 (reader): Use trace_flag to enable scanner/parser debugging,
6813 instead of an adhoc scheme.
6814 * src/scan-gram.l: Remove trailing debugging code.
6815
6816 2002-10-16 Paul Eggert <eggert@twinsun.com>
6817
6818 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
6819 MUSCLE_TAB_H.
6820
6821 * NEWS: Officially drop support for building Bison with K&R C,
6822 since it didn't work anyway and it's not worth worrying about.
6823 * Makefile.maint (wget_files): Remove ansi2knr.c.
6824 (ansi2knr.c-url_prefix): Remove.
6825 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
6826 * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
6827 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
6828
6829 2002-10-15 Paul Eggert <eggert@twinsun.com>
6830
6831 Stop using the "enum_" trick for K&R-style function definitions;
6832 it confused me, and I was the author! Instead, assume that people
6833 who want to use K&R C compilers (when using these modules in GCC,
6834 perhaps?) will run ansi2knr.
6835
6836 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
6837 All uses of "enum_" changed to "enum ".
6838 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
6839 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
6840

6849 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
6850 Use function prototypes; this removes the need for declaring
6851 static functions simply to provide their prototypes.
6852 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

6908
6909 2002-10-14 Akim Demaille <akim@epita.fr>
6910
6911 * tests/Makefile.am (maintainer-check-posix): New.
6912
6913 2002-10-14 Akim Demaille <akim@epita.fr>
6914
6915 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
6916 member.
6917
6918 2002-10-14 Akim Demaille <akim@epita.fr>
6919
6920 * src/tables.c (table_ninf_remap): base -> tab.
6921 Reported by Matt Rosing.
6922
6923 2002-10-14 Paul Eggert <eggert@twinsun.com>
6924
6925 * tests/action.at, tests/calc.at, tests/conflicts.at,
6926 tests/cxx-type.at, tests/headers.at, tests/input.at,
6927 tests/regression.at, tests/synclines.at, tests/torture.at:
6928 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
6929 so that the tests still work even if POSIXLY_CORRECT is set.
6930 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
6931
6932 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
6933 for portability to K&R hosts. Fix typo: signed char is guaranteed
6934 only to 127, not to 128.
6935 * data/glr.c (yysigned_char): New type.
6936 * data/yacc.c (yysigned_char): Likewise.
6937 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
6938
6939 2002-10-13 Paul Eggert <eggert@twinsun.com>
6940
6941 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
6942 true due to limited range of data type" warning from GCC.
6943
6944 * data/c.m4 (b4_token_defines): Protect against double-inclusion
6945 by wrapping enum yytokentype's definition inside #ifndef
6946 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
6947
6948 2002-10-13 Akim Demaille <akim@epita.fr>
6949
6950 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
6951 Un yy- yyrhs to avoid the name clash with the global YYRHS.
6952
6953 2002-10-13 Akim Demaille <akim@epita.fr>
6954
6955 * Makefile.maint: Update from Autoconf 2.54.
6956 * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Remove, shipped with 2.54.
6957
6958 2002-10-13 Akim Demaille <akim@epita.fr>
6959
6960 * src/print.c (print_state): Separate the list of solved conflicts
6961 from the other items.
6962 * tests/conflicts.at (Resolved SR Conflicts): Adjust.
6963
6964 2002-10-13 Akim Demaille <akim@epita.fr>
6965
6966 Let nondeterministic skeletons be usable with deterministic
6967 tables.
6968
6969 With the patch, GAWK compiled by GCC without -O2 passes its test
6970 suite using a GLR parser driven by LALR tables. It fails with -O2
6971 because `struct stat' gives two different answers on my machine:
6972 88 (definition of an auto var) and later 96 (memset on this var).
6973 Hence the stack is badly corrumpted. The headers inclusion is to
6974 blame: if I move the awk.h inclusion before GLR's system header
6975 inclusion, the two struct stat have the same size.
6976
6977 * src/tables.c (pack_table): Always create conflict_table.
6978 (token_actions): Always create conflict_list.
6979 * data/glr.c (YYFLAG): Remove, unused.
6980
6981 2002-10-13 Akim Demaille <akim@epita.fr>
6982
6983 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
6984 (O0FLAGS): New.
6985 (VALGRIND, GXX): New.
6986 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
6987 * tests/bison.in: Run $PREBISON a pre-command.
6988 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
6989 (maintainer-check-g++): New.
6990 * Makefile.am (maintainer-check): New.
6991
6992 2002-10-13 Akim Demaille <akim@epita.fr>
6993
6994 * data/glr.c: Formatting changes.
6995 Tweak some trace messages to match yacc.c's.
6996
6997 2002-10-13 Akim Demaille <akim@epita.fr>
6998
6999 GLR parsers sometimes raise parse errors instead of performing the
7000 default reduction.
7001 Reported by Charles-Henry de Boysson.
7002
7003 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
7004 check the length of the traces when %glr.
7005 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
7006 GLR's traces.
7007 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
7008 Test GLR parsers.
7009 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
7010 (yyltype): Remove the yy prefix from the member names.
7011 (yytable): Complete its comment.
7012 (yygetLRActions): Map error action number from YYTABLE from
7013 YYTABLE_NINF to 0.
7014 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
7015 (which was a bug: it should have been YYTABEL_NINF, and yet it was
7016 not satisfying as we could compare an YYACTION computed from
7017 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
7018 only value for error actions.
7019 (yyreportParseError): In verbose parse error messages, don't issue
7020 `error' in the list of expected tokens.
7021 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
7022 next action to perform to match glr.c's decoding.
7023 (yytable): Complete its comment.
7024
7025 2002-10-13 Paul Eggert <eggert@twinsun.com>
7026
7027 Fix problem reported by Henrik Grubbstroem in
7028 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
7029 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
7030 because the Bison parser reads the second action before reducing
7031 the first one.
7032 * src/scan-gram.l (rule_length): New static var.
7033 Use it to keep track of the rule length in the scanner, since
7034 we can't expect the parser to be in lock-step sync with the scanner.
7035 (handle_action_dollar, handle_action_at): Use this var.
7036 * tests/actions.at (Exotic Dollars): Test for the problem.
7037
7038 2002-10-12 Paul Eggert <eggert@twinsun.com>
7039
7040 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
7041 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
7042 Include <sys/time.h> when checking for clock_t and struct tms.
7043 Use same include order as source.
7044 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
7045 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
7046
7047 * lib/timevar.c: Update copyright date and clarify comments.
7048 (get_time) [IN_GCC]: Keep the GCC version for reference.
7049
7050 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
7051 GCC version as of today, then merge Bison's changes.
7052 Change "GCC" to "Bison" in copyright notice. timevar.def's
7053 author is Akim, so change that too.
7054
7055 * src/reader.c (grammar_current_rule_check):
7056 Don't worry about the default action if $$ is untyped.
7057 Prevents bogus warnings reported by Jim Gifford in
7058 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
7059
7060 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
7061 * data/glr.c, data/lalr1.cc, data/yacc.c:
7062 Output token definitions before the first part of user declarations.
7063 Fixes compatibility problem reported by Jim Gifford for kbd in
7064 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
7065
7066 2002-10-11 Paul Eggert <eggert@twinsun.com>
7067
7068 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...

7085
7086 Portability fixes for bitsets; this also avoids several GCC
7087 warnings.
7088
7089 * lib/abitset.c: Include <stddef.h>, for offsetof.
7090 * lib/lbitset.c: Likewise.
7091
7092 * lib/abitset.c (abitset_bytes): Return a size that is aligned
7093 properly for vectors of objects. Do not assume that adding a
7094 header size to a multiple of a word size yields a value that is
7095 properly aligned for the whole union.
7096 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7097
7098 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
7099 unique names for structures.
7100 * lib/ebitset.c (ebitset_bytes): Likewise.
7101 * lib/lbitset.c (lbitset_bytes): Likewise.
7102
7103 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
7104 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
7105 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
7106 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
7107 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
7108 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
7109 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
7110 to improve the type-checking that GCC can do.
7111 * lib/bitset.c (bitset_op4_cmp): Likewise.
7112 * lib/bitset_stats.c (bitset_stats_count,
7113 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
7114 bitset_stats_copy, bitset_stats_disjoint_p,
7115 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
7116 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
7117 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
7118 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
7119 bitset_stats_and_or_cmp, bitset_stats_andn_or,
7120 bitset_stats_andn_or_cmp, bitset_stats_or_and,
7121 bitset_stats_or_and_cmp): Likewise.
7122 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
7123 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
7124 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
7125 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
7126
7127 * lib/abitset.h: Include bitset.h, not bbitset.h.
7128 * lib/ebitset.h: Likewise.
7129 * lib/lbitset.h: Likewise.
7130
7131 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
7132 All instances of parameters of type enum bitset_opts are now of
7133 type enum_bitset_opts, to conform to the C Standard, and similarly
7134 for enum_bitset_type.
7135 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
7136 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
7137
7138 Do not use "struct bitset_struct" to mean different things in
7139 different modules. Not only is this confusing, it violates
7140 the C Standard, which requires that structure types in different
7141 modules must be compatible if one is to be passed to the other.
7142 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
7143 All instances of "struct bitset_struct *" replaced with "bitset".
7144 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
7145 (union bitset_union, struct abitset_struct, struct ebitset_struct,
7146 struct lbitset_struct, struct bitset_stats_struct): New types.
7147 All uses of struct bitset_struct changed to union bitset_union,
7148 etc.
7149 * lib/abitset.c (struct abitset_struct, abitset,
7150 struct bitset_struct): Remove.
7151 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
7152 struct bitset_struct): Remove.
7153 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
7154 bitset_struct): Remove.
7155 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
7156 Likewise.
7157
7158 Do not call a function of type T using a call that assumes the
7159 function is of a different type U. Standard C requires that a
7160 function must be called with a type that is compatible with its
7161 definition.
7162 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
7163 New decls.
7164 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
7165 New functions.
7166 * lib/ebitset.c (PFV): Remove.
7167 * lib/lbitset.c (PFV): Likewise.
7168 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
7169 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
7170 decls.
7171 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
7172 (ebitset_vtable): Use them.
7173 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
7174 lbitset_xor): New functions.
7175 (lbitset_vtable): Use them.
7176
7177 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
7178 Declare.
7179
7180 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
7181 GCC warning.
7182 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
7183 Use offsetof, for simplicity.
7184
7185 2002-10-06 Paul Eggert <eggert@twinsun.com>
7186
7187 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
7188 the same width as int. This reapplies a hunk of the 2002-08-12 patch
7189 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
7190 which was inadvertently undone by the 2002-09-30 patch.
7191 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
7192 the same width as int.
7193

7199
7200 * doc/bison.texinfo: Minor spelling, grammar, and white space
7201 fixes.
7202 (Symbols): Mention that any negative value returned from yylex
7203 signifies end-of-input. Warn about negative chars. Mention
7204 the portable Standard C character set.
7205
7206 The GNU coding standard says CFLAGS and YFLAGS are reserved
7207 for the installer to set.
7208 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
7209 * src/Makefile.am (AM_CFLAGS): Likewise.
7210 (AM_YFLAGS): Renamed from YFLAGS.
7211
7212 Fix some MAX and MIN problems.
7213 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
7214 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
7215 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
7216 * src/reader.c (reader): Use it.
7217
7218 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
7219 POSIX 1003.1-2001 has removed fgrep.
7220

7226
7227 2002-10-01 Paul Eggert <eggert@twinsun.com>

7256 * lib/abitset.h (abitset_bytes): Likewise.
7257 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
7258 Likewise.

7272 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
7273 abitset_or_and, abitset_or_and_cmp):
7274 Use bitset_windex instead of unsigned int.
7275 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
7276 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
7277 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,
7278 ebitset_elt_find, ebitset_list_reverse, ebitset_list, ebitset_init):
7279 Likewise.
7280 * lib/lbitset.c (lbitset_ones, lbitset_not): Likewise.

7292 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
7293 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
7294 to BITSET_WINDEX_MAX.
7295
7296 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
7297 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

7492
7493 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
7494 PROTOTYPES to check for prototypes, and "defined __STDC__" to
7495 check for void *.
7496
7497 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
7498 size_t; the old version tried to do this but casted improperly.
7499 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
7500 (bitset_test): Now returns int, not unsigned long.
7501
7502 * lib/bitset_stats.c: Include "gettext.h".
7503 (_): New macro.
7504 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
7505 name locals "index", as it generates unnecessary warnings on some
7506 hosts that have an "index" function.
7507
7508 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
7509 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

7530 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
7531 lib/timevar.c.
7532 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
7533 manual recommends.
7534 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
7535
7536 * src/complain.c (strerror_r): Remove decl; not needed.
7537 (strerror): Use same pattern as ../lib/error.c.
7538

7540
7541 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
7542
7543 * src/main.c (main): Cast result of bindtextdomain and textdomain
7544 to void, to avoid a GCC warning when --disable-nls is in effect.
7545
7546 * src/scan-gram.l: Use strings rather than escapes when possible,
7547 to minimize the number of warnings from xgettext.
7548 (handle_action_dollar, handle_action_at): Don't use isdigit,
7549 as it mishandles negative chars and it may not work as expected
7550 outside the C locale.
7551
7552 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
7553 this is a GCC extension and is not portable to other compilers.
7554
7555 * src/system.h (alloca): Use same pattern as ../lib/error.c.
7556 Do not include <ctype.h>; no longer needed.
7557 Do not include <malloc.h>; no longer needed (and generates
7558 warnings on OpenBSD 3.0).
7559
7560 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
7561 it's not portable.
7562
7563 * tests/regression.at: Do not use 'cc -c input.c -o input';
7564 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
7565
7566 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
7567 exit status as failure, not just exit status 1. Sun C exits
7568 with status 2 sometimes.
7569
7570 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
7571 Use it for the two large tests.
7572
7573 2002-08-02 Akim Demaille <akim@epita.fr>
7574
7575 * src/conflicts.c (conflicts_output): Don't output rules never
7576 reduced here, since anyway that computation doesn't work.
7577 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
7578 (rule_useless_p, rule_never_reduced_p): New.

7583 * src/tables.c (action_row): Move the computation of rules never
7584 reduced to...
7585 (token_actions): here.
7586 * src/main.c (main): Make the parser before making the report, so
7587 that rules never reduced are computed.
7588 Call grammar_rules_never_reduced_report.
7589 * src/print.c (print_results): Report rules never reduced.
7590 * tests/conflicts.at, tests/reduce.at: Adjust.
7591
7592 2002-08-01 Akim Demaille <akim@epita.fr>
7593

7595 reduced by a state, attach the lookaheads to the reductions.
7596
7597 * src/state.h (state_t): Remove the `lookaheads',
7598 `lookaheads_rule' member.
7599 (reductions_t): Add a `lookaheads' member.
7600 Use a regular array for the `rules'.

7611 (initialize_LA): this.
7612 (lalr_free): Adjust.
7613 * src/main.c (main): Don't free nullable and derives too early: it

7623 Adjust all dependencies.
7624 * src/nullable.c (set_nullable, free_nullable): Rename as...
7625 (nullable_compute, nullable_free): these.
7626 (rule_list_t): Store rule_t *, not rule_number_t.
7627 * src/state.c (state_rule_lookaheads_print): Directly compare rule
7628 pointers, instead of their numbers.
7629 * src/main.c (main): Call nullable_free, and derives_free earlier,
7630 as they were lo longer used.
7631
7632 2002-08-01 Akim Demaille <akim@epita.fr>
7633
7634 * lib/timevar.c (get_time): Include children time.
7635 * src/lalr.h (LA, LArule): Don't export them: used with the
7636 state_t.
7637 * src/lalr.c (LA, LArule): Static.

7641 table_size, not >.
7642 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
7643 (tables_generate): do it, since that's also it which allocates
7644 them.
7645 Don't free LA and LArule, main does.
7646
7647 2002-07-31 Akim Demaille <akim@epita.fr>

7684 --trace=time.
7685 * src/main.c (stage): Remove.
7686 (main): Replace `stage' invocations with timevar calls.
7687 * src/output.c: Insert pertinent timevar calls.

7712 expected token.
7713 * tests/actions.at (Printers and Destructors): Adjust.
7714 * tests/calc.at (Calculator $1): Adjust.
7715 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
7716 error message, do not report the parser accepts the error token in
7717 that state.

7732 by conflicts.
7733
7734 * src/LR0.c (save_reductions): Don't make the final state too
7735 different: save its reduction (accept) instead of having a state
7736 without any action (no shift or goto, no reduce).
7737 Note: the final state is now a ``regular'' state, i.e., the
7738 parsers now contain `reduce 0' as default reduction.
7739 Nevertheless, since they decide to `accept' when yystate =
7740 final_state, they still will not reduce rule 0.
7741 * src/print.c (print_actions, print_reduction): Adjust.
7742 * src/output.c (action_row): Track reduced rules.
7743 (token_actions): Report rules never reduced.

7782
7783 2002-07-26 Akim Demaille <akim@epita.fr>
7784
7785 * src/reader.h, src/reader.c (gram_error): ... can't get
7786 yycontrol without making too strong assumptions on the parser
7787 itself.
7788 * src/output.c (prepare_tokens): Use the real 0th value of
7789 token_translations instead of `0'.
7790 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
7791 visible here.
7792 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
7793 for the time being: %locations ought to provide it to yyerror.
7794
7795 2002-07-25 Akim Demaille <akim@epita.fr>
7796
7797 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

7806 * src/nullable.c, src/output.c, src/print.c, src/reader.c
7807 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
7808 Iterate from 0 to nrules.
7809 Use rule_number_as_item_number and item_number_as_rule_number.
7810 Adjust to `derive' now containing possibly 0.
7811 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
7812 Handle the `- 1' part in rule numbers from/to item numbers.

7888
7889 2002-07-09 Akim Demaille <akim@epita.fr>
7890

8865 (AT_DATA_HORIZONTAL_GRAMMAR): Respect the `%token ID NUM STRING'
8866 grammar.

8872 stricter %token grammar.

8894 * src/reader.c (parse_action): Don't store directly into the
8895 rule's action member: return the action as a string.

8898 (grammar_current_rule_action_append): New, eved out from
8899 (readgram): here.

8917
8918 * src/reader.c (grammar_rule_begin, previous_rule, current_rule):
8919 New.
8920 (readgram): Use them as replacement of inlined code, crule and
8921 crule1.
8922
8923 2002-06-11 Akim Demaille <akim@epita.fr>

8925 * src/reader.c (grammar_end, grammar_symbol_append): New.

8929 2002-06-10 Akim Demaille <akim@epita.fr>
8930
8931 GCJ's parser requires the tokens to be defined before the prologue.

8940
8941 * src/symtab.c (symbol_user_token_number_set): Don't complain when
8942 assigning twice the same user number to a token, so that we can
8943 use it in...
8944 * src/lex.c (lex): here.
8945 Also use `symbol_class_set' instead of hand written code.
8946 * src/reader.c (parse_assoc_decl): Likewise.

8957
8958 Remove `%thong' support as it is undocumented, unused, duplicates
8959 `%token's job, and creates useless e-mail traffic with people who
8960 want to know what it is, why it is undocumented, unused, and
8961 duplicates `%token's job.
8962
8963 * src/reader.c (parse_thong_decl): Remove.

9332 (parse_guard): Rename the formal argument `stack_offset' as
9333 `rule_length', which is more readable.
9334 Adjust callers.
9335 (copy_at, copy_dollar): Instead of outputting the hard coded
9336 values of $$, $n and so forth, output invocation to b4_lhs_value,
9337 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
9338 Note: this patch partially drops `semantic-parser' support: it
9339 always does `rule_length - n', where semantic parsers ought to
9340 always use `-n'.

9445 2002-04-22 Akim Demaille <akim@epita.fr>
9446
9447 * src/reader.c (token_translations_init): 256 is now the default
9448 value for the error token, i.e., it will be assigned another
9449 number if the user assigned 256 to one of her tokens.

9451 * doc/bison.texinfo (Symbols): Adjust.
9452 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
9453 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
9454 etc. instead of 10, 20, 30 (which was used to `jump' over error
9455 (256) and undefined (2)).
9456
9457 2002-04-22 Akim Demaille <akim@epita.fr>
9458

9491
9492 2002-04-09 Akim Demaille <akim@epita.fr>
9493
9494 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
9495 full stderr, and strip it according to the bison options, instead
9496 of composing the error message from different bits.
9497 This makes it easier to check for several error messages.
9498 Adjust all the invocations.
9499 Add an invocation exercising the error token.
9500 Add an invocation demonstrating a stupid error message.
9501 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

9512 * src/symtab.h: here.
9513 (state_t.number): Is a token_number_t.
9514 * src/print.c, src/reader.c: Use undeftoken->number instead of
9515 hard coded 2.
9516 (Even though this 2 is not the same as above: the number of the
9517 undeftoken remains being 2, it is its user token number which
9518 might not be 2).
9519 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
9520 `user_token_number_max'.
9521 Output `undef_token_number'.
9522 * data/bison.simple, data/bison.c++: Use them.
9523 Be sure to map invalid yylex return values to
9524 `undef_token_number'. This saves us from gratuitous SEGV.

9543 RITEM. Note that it must be able to code symbol numbers as
9544 positive number, and the negation of rule numbers as negative
9545 numbers.
9546 Adjust all dependencies (pretty many).
9547 * src/reduce.c (rule): Remove this `short *' pointer: use
9548 item_number_t.
9549 * src/system.h (MINSHORT, MAXSHORT): Remove.
9550 Include `limits.h'.
9551 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

9558 500.
9559 * tests/regression.at (Web2c Actions): Ajust.
9560
9561 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
9562 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
9563 passes, but produces negative #line number, once fixed, GCC is
9564 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
9565 C), it passes.
9566 * src/state.h (state_h): Code input lines on ints, not shorts.
9567
9568 2002-04-08 Akim Demaille <akim@epita.fr>

9664

9680 2002-04-07 Akim Demaille <akim@epita.fr>

9686
9687 2002-04-07 Akim Demaille <akim@epita.fr>

9689 As a result of the previous patch, it is no longer needed
9690 to reorder ritem itself.
9691
9692 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
9693
9694 2002-04-07 Akim Demaille <akim@epita.fr>

9700 (prepare_tokens): this.

9708 (output_stos): Rename as...

9711 in the output if you don't need it.
9712
9713 2002-04-07 Akim Demaille <akim@epita.fr>
9714
9715 * src/LR0.c (new_state): Display `nstates' as the name of the
9716 newly created state.
9717 Adjust to initialize first_state and last_state if needed.
9718 Be sure to distinguish the initial from the final state.
9719 (new_states): Create the itemset of the initial state, and use
9720 new_state.
9721 * src/closure.c (closure): Now that the initial state has its
9722 items properly set, there is no need for a special case when
9723 creating `ruleset'.
9724
9725 As a result, now the rule 0, reducing to $axiom, is visible in the
9726 outputs. Adjust the test suite.

9745 `number' of the buckets too.
9746 * src/gram.h: Include `symtab.h'.
9747 (associativity): Move to...
9748 * src/symtab.h: here.
9749 No longer include `gram.h'.

9761 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

9763
9764 2002-04-07 Akim Demaille <akim@epita.fr>
9765
9766 * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
9767 lacking `+ 1' to nrules, Bison reported as useless a token if it
9768 was used solely to set the precedence of the last rule...
9769
9770 2002-04-07 Akim Demaille <akim@epita.fr>
9771
9772 * data/bison.c++, data/bison.simple: Don't output the current file
9773 name in #line, to avoid useless diffs between two identical
9774 outputs under different names.
9775
9776 2002-04-07 Akim Demaille <akim@epita.fr>
9777
9778 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

9793 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
9794 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
9795 RHS, instead of being an index in RITEMS.

10065
10066 Remove the support for C++ namespace cleanliness; it was
10067 causing more problems than it was curing, since it didn't work

10099 * tests/regression.at (%nonassoc and eof): Don't include
10100 nonportable headers.
10101
10102 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
10103
10104 * data/bison.c++: Correct error recovery. Make the user able to
10105 initialize the starting location.
10106
10107 2002-02-07 Akim Demaille <akim@epita.fr>
10108
10109 * tests/input.at: New.
10110
10111 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10112
10113 * data/bison.c++: Replace some direct m4 expansions by constants. Be
10114 more consistent when naming methods and variables. Put preprocessor
10115 directives around tables only needed for debugging.
10116
10117 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10118
10119 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
10120 C++ parsers.
10121 (yy::b4_name::parse): Use print_.
10122
10123 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10124
10125 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
10126
10127 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
10128
10129 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
10130 C++ parsers.
10131 (yy::b4_name::parse): Build verbose error messages, and use error_.
10132
10133 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10134
10135 * data/bison.c++: Fix m4 quoting in comments.
10136
10137 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
10138
10139 * data/bison.c++: Adjust the parser code. Fix some muscles that were
10140 not expanded by m4.
10141
10142 2002-02-05 Akim Demaille <akim@epita.fr>
10143
10144 * data/bison.c++: Adjust to the M4 back end.
10145 More is certainly needed.
10146
10147 2002-02-05 Akim Demaille <akim@epita.fr>
10148
10149 Give a try to M4 as a back end.
10150
10151 * lib/readpipe.c: New, from wdiff.
10152 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
10153 BISON_HAIRY.
10154 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
10155 specific values. Now it is m4 that performs the lookup.
10156 * src/parse-skel.y: Remove.
10157 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
10158 * src/output.c (actions_output, guards_output)
10159 (token_definitions_output): No longer keeps track of the output
10160 line number, hence remove the second argument.
10161 (guards_output): Check against the guard member of a rule, not the
10162 action member.
10163 Adjust callers.
10164 (output_skeleton): Don't look for the skeleton location, let m4 do
10165 that.
10166 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
10167 file will be used.
10168 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
10169 (prepare): Given that for the time being changesyntax is not
10170 usable in M4, rename the muscles using `-' to `_'.
10171 Define `defines_flag', `output_parser_name' and `output_header_name'.
10172 * src/output.h (actions_output, guards_output)
10173 (token_definitions_output): Adjust prototypes.
10174 * src/scan-skel.l: Instead of scanning the skeletons, it now
10175 processes the output of m4: `__oline__' and `#output'.
10176 * data/bison.simple: Adjust to be used by M4(sugar).
10177 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
10178 to date.
10179 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
10180 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
10181 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
10182 shamelessly stolen from CVS Autoconf.
10183
10184 2002-02-05 Akim Demaille <akim@epita.fr>
10185
10186 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
10187 * configure.in: Check for the declarations of free and malloc.
10188 * src/muscle_tab.c: Adjust.
10189
10190 2002-02-05 Akim Demaille <akim@epita.fr>
10191
10192 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
10193 which have no values.
10194
10195 2002-02-05 Akim Demaille <akim@epita.fr>
10196
10197 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
10198 * data/: here.
10199
10200 2002-01-29 Paul Eggert <eggert@twinsun.com>
10201
10202 * src/bison.simple (YYSIZE_T): Do not define merely because
10203 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
10204 On some platforms, <alloca.h> does not declare YYSTD (size_t).
10205
10206 2002-01-27 Akim Demaille <akim@epita.fr>
10207
10208 Fix `%nonassoc and eof'.
10209
10210 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
10211 which were not properly copied! Replace
10212 memcpy (res->errs, src->errs, src->nerrs);
10213 with
10214 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
10215 !!!
10216 * tests/regression.at (%nonassoc and eof): Adjust to newest
10217 Autotest: `.' is not in the PATH.
10218
10219 2002-01-27 Akim Demaille <akim@epita.fr>
10220
10221 * tests/sets.at (AT_EXTRACT_SETS): New.
10222 (Nullable): Use it.
10223 (Firsts): New.
10224
10225 2002-01-26 Akim Demaille <akim@epita.fr>
10226
10227 * tests/actions.at, tests/calc.at, tests/headers.at,
10228 * tests/torture.at: Adjust to the newest Autotest which no longer
10229 forces `.' in the PATH.
10230
10231 2002-01-25 Akim Demaille <akim@epita.fr>
10232
10233 * tests/regression.at (%nonassoc and eof): New.
10234 Suggested by Robert Anisko.
10235
10236 2002-01-24 Akim Demaille <akim@epita.fr>
10237
10238 Bison dumps core when trying to complain about broken input files.
10239 Reported by Cris van Pelt.
10240
10241 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
10242 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
10243 into...
10244 (Invalid inputs): Strengthen: exercise parse_percent_token.
10245
10246 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
10247
10248 * src/Makefile.am: Add bison.c++.
10249 * src/bison.c++: New skeleton.
10250
10251 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
10252
10253 * po/it.po: New.
10254
10255 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
10256
10257 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
10258
10259 2002-01-20 Marc Autret <marc@gnu.org>
10260
10261 * src/files.c (compute_output_file_names): Fix
10262
10263 2002-01-20 Marc Autret <marc@gnu.org>
10264
10265 * tests/output.at: New test.
10266 * src/files.c (compute_base_names): Don't map extensions when
10267 the YACC flag is set, use defaults.
10268 Reported by Evgeny Stambulchik.
10269
10270 2002-01-20 Marc Autret <marc@gnu.org>
10271
10272 * src/system.h: Need to define __attribute__ away for non-GCC
10273 compilers as well (i.e., the vendor C compiler).
10274 Suggested by Albert Chin-A-Young.
10275
10276 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
10277
10278 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
10279 canonical definition.
10280 * src/system.h: Use the canonical definition for PARAMS (avoids
10281 a conflict with the macro from lib/hash.h).
10282
10283 2002-01-11 Akim Demaille <akim@epita.fr>
10284
10285 * configure.in: Use AC_FUNC_STRNLEN.
10286 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
10287
10288 2002-01-09 Akim Demaille <akim@epita.fr>
10289
10290 * src/files.c, src/files.h (output_infix): New.
10291 (tab_extension): Remove.
10292 (compute_base_names): Compute the former, drop the latter.
10293 * src/output.c (prepare): Insert the muscles `output-infix', and
10294 `output-suffix'.
10295 * src/parse-skel.y (string, string.1): New.
10296 (section.header): Use it.
10297 (section.yacc): Remove.
10298 (prefix): Remove too.
10299 * src/scan-skel.l: Adjust.
10300 * src/bison.simple, src/bison.hairy: Adjust.
10301
10302 2002-01-09 Akim Demaille <akim@epita.fr>
10303
10304 * configure.in (WERROR_CFLAGS): Compute it.
10305 * src/Makefile.am (CFLAGS): Pass it.
10306 * tests/atlocal.in (CFLAGS): Idem.
10307 * src/files.c: Fix a few warnings.
10308 (get_extension_index): Remove, unused.
10309
10310 2002-01-08 Akim Demaille <akim@epita.fr>
10311
10312 * src/getargs.c (AS_FILE_NAME): New.
10313 (getargs): Use it to convert DOSish file names.
10314 * src/files.c (base_name): Rename as full_base_name to avoid
10315 clashes with `base_name ()'.
10316 (filename_split): New.
10317 (compute_base_names): N-th rewrite, using filename_split.
10318
10319 2002-01-08 Akim Demaille <akim@epita.fr>
10320
10321 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
10322 New, stolen from the Fileutils 4.1.
10323 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
10324 * configure.in: Check for the presence of memrchr, and of its
10325 prototype.
10326
10327 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
10328
10329 * lib/hash.h (__P): Added definition for this macro.
10330 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
10331 BUILT_SOURCES, to ensure they are generated first.
10332 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
10333 %error-verbose to allow bootstrapping with bison 1.30x.
10334
10335 2002-01-06 Akim Demaille <akim@epita.fr>
10336
10337 * src/reader.c (parse_braces): Don't fetch the next char, the
10338 convention is to fetch on entry.
10339 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
10340 'switch' without a following semicolon.
10341 * tests/regression.at (braces parsing): New.
10342
10343 2002-01-06 Akim Demaille <akim@epita.fr>
10344
10345 Bison is dead wrong in its RR conflict reports.
10346
10347 * tests/torture.at (GNU Cim Grammar): New.
10348 * src/conflicts.c (count_rr_conflicts): Fix.
10349
10350 2002-01-06 Akim Demaille <akim@epita.fr>
10351
10352 Creating package.m4 from configure.ac causes too many problems.
10353
10354 * tests/Makefile.am (package.m4): Create it by hand,
10355 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
10356
10357 2002-01-06 Akim Demaille <akim@epita.fr>
10358
10359 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
10360 skeleton.h.
10361
10362 2002-01-04 Paul Eggert <eggert@twinsun.com>
10363
10364 * doc/bison.texinfo (Debugging):
10365 Remove YYSTDERR; it's no longer defined or used.
10366 Also, s/cstdio.h/cstdio/.
10367
10368 2002-01-03 Akim Demaille <akim@epita.fr>
10369
10370 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
10371
10372 2002-01-03 Akim Demaille <akim@epita.fr>
10373
10374 * src/parse-skel.y (process_skeleton): Don't bind the parser's
10375 tracing code to --trace, wait for a better --trace option, with
10376 args.
10377
10378 2002-01-03 Akim Demaille <akim@epita.fr>
10379
10380 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
10381 The ISO C++ standard is extremely clear about it: stderr is
10382 considered a macro, not a regular symbol (see table 94 `Header
10383 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
10384 Therefore std:: does not apply to it. It still does with fprintf.
10385 Also, s/cstdio.h/cstdio/.
10386
10387 2002-01-03 Akim Demaille <akim@epita.fr>
10388
10389 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
10390 for non system headers.
10391
10392 2002-01-02 Akim Demaille <akim@epita.fr>
10393
10394 Equip the skeleton chain with location tracking, runtime trace,
10395 pure parser and scanner.
10396
10397 * src/parse-skel.y: Request a pure parser, locations, and prefix
10398 renaming.
10399 (%union): Having several members with the same type does not help
10400 type mismatches, simplify.
10401 (YYPRINT, yyprint): New.
10402 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
10403 (skel_error): this.
10404 Handle locations.
10405 * src/scan-skel.l: Adjust to these changes.
10406 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
10407 (LOCATION_PRINT, skel_control_t): New.
10408
10409 2001-12-30 Akim Demaille <akim@epita.fr>
10410
10411 * src/parse-skel.y: Get rid of the shift/reduce conflict:
10412 replace `gb' with BLANKS.
10413 * src/scan-skel.l: Adjust.
10414
10415 2001-12-30 Akim Demaille <akim@epita.fr>
10416
10417 * src/system.h: We don't need nor want bcopy.
10418 Throw away MS-DOS crap: we don't need getpid.
10419 * configure.in: We don't need strndup. It was even causing
10420 problems: because Flex includes the headers *before* us,
10421 _GNU_SOURCE is not defined by config.h, and therefore strndup was
10422 not visible.
10423 * lib/xstrndup.c: New.
10424 * src/scan-skel.l: Use it.
10425 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
10426 * src/parse-skel.y: Use %directives instead of #defines.
10427
10428 2001-12-30 Akim Demaille <akim@epita.fr>
10429
10430 * src/skeleton.h: New.
10431 * src/output.c (output_parser, output_master_parser): Remove, dead
10432 code.
10433 * src/output.h (get_lines_number, actions_output, guards_output)
10434 (token_definitions_output): Prototype them.
10435 * src/parse-skel.y: Add the license notice.
10436 Include output.h and skeleton.h.
10437 (process_skeleton): Returns void, and takes a single parameter.
10438 * src/scan-skel.l: Add the license notice.
10439 Include skeleton.h.
10440 Don't use %option yylineno: it seems that then Flex imagines
10441 REJECT has been used, and therefore it won't reallocate its
10442 buffers (which makes no other sense to me than a bug). It results
10443 in warnings for `unused: yy_flex_realloc'.
10444
10445 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
10446
10447 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10448 (MUSCLE_INSERT_PREFIX): ...to there.
10449 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
10450 (MUSCLE_INSERT_PREFIX): Move from here...
10451
10452 * src/bison.hairy: Add a section directive. Put braces around muscle
10453 names. This parser skeleton is still broken, but Bison should not
10454 choke on a bad muscle 'syntax'.
10455 * src/bison.simple: Add a section directive. Put braces around muscle
10456 names.
10457
10458 * src/files.h (strsuffix, stringappend): Add declarations.
10459 (tab_extension): Add declaration.
10460 (short_base_name): Add declaration.
10461
10462 * src/files.c (strsuffix, stringappend): No longer static. These
10463 functions are used in the skeleton parser.
10464 (tab_extension): New.
10465 (compute_base_names): Use the computations done in this function
10466 to guess if the generated parsers should have '.tab' in their
10467 names.
10468 (short_base_name): No longer static.
10469
10470 * src/output.c (output_skeleton): New.
10471 (output): Disable call to output_master_parser, and give a try to
10472 a new skeleton handling system.
10473 (guards_output, actions_output): No longer static.
10474 (token_definitions_output, get_lines_number): No longer static.
10475
10476 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
10477
10478 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
10479 parse-skel.y.
10480
10481 * src/parse-skel.y: New file.
10482 * src/scan-skel.l: New file.
10483
10484 2001-12-29 Akim Demaille <akim@epita.fr>
10485
10486 %name-prefix is broken.
10487
10488 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
10489 Adjust all dependencies.
10490 * tests/headers.at (export YYLTYPE): Strengthen this test: use
10491 %name-prefix.
10492
10493 Renaming yylval but not yylloc is not consistent. Now we do.
10494
10495 * src/bison.simple: Prefix yylloc if used.
10496 * doc/bison.texinfo (Decl Summary): Document that.
10497
10498 2001-12-29 Akim Demaille <akim@epita.fr>
10499
10500 * doc/bison.texinfo: Promote `%long-directive' over
10501 `%long_directive'.
10502 Remove all references to fixed-output-files, yacc is enough.
10503
10504 2001-12-29 Akim Demaille <akim@epita.fr>
10505
10506 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
10507 user prologue. These are defaults.
10508 * tests/actions.at (Mid-rule actions): Make sure the user can
10509 define YYDEBUG and YYERROR_VERBOSE.
10510
10511 2001-12-29 Akim Demaille <akim@epita.fr>
10512
10513 * src/output.c (header_output): Don't forget to export YYLTYPE and
10514 yylloc.
10515 * tests/headers.at (export YYLTYPE): New, make sure it does.
10516 * tests/regression.at (%union and --defines, Invalid CPP headers):
10517 Move to...
10518 * tests/headers.at: here.
10519
10520 2001-12-29 Akim Demaille <akim@epita.fr>
10521
10522 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
10523
10524 2001-12-29 Akim Demaille <akim@epita.fr>
10525
10526 * tests/actions.at (Mid-rule actions): Output on a single line
10527 instead of several.
10528
10529 2001-12-29 Akim Demaille <akim@epita.fr>
10530
10531 * doc/bison.texinfo: Formatting changes.
10532
10533 2001-12-29 Akim Demaille <akim@epita.fr>
10534
10535 Don't store the token defs in a muscle, just be ready to output it
10536 on command. Now possible via `symbols'. Fixes a memory leak.
10537
10538 * src/output.c (token_definitions_output): New.
10539 (output_parser, header_output): Use it.
10540 * src/reader.c (symbols_save): Remove.
10541
10542 2001-12-29 Akim Demaille <akim@epita.fr>
10543
10544 * src/bison.simple: Do not provide a default for YYSTYPE and
10545 YYLTYPE before the user's prologue. Otherwise it's hardly... a
10546 default.
10547
10548 2001-12-29 Akim Demaille <akim@epita.fr>
10549
10550 Mid-rule actions are simply... ignored!
10551
10552 * src/reader.c (readgram): Be sure to attach mid-rule actions to
10553 the empty-rule associated to the dummy symbol, not to the host
10554 rule.
10555 * tests/actions.at (Mid-rule actions): New.
10556
10557 2001-12-29 Akim Demaille <akim@epita.fr>
10558
10559 Memory leak.
10560
10561 * src/reader.c (reader): Free grammar.
10562
10563 2001-12-29 Akim Demaille <akim@epita.fr>
10564
10565 Memory leak.
10566
10567 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
10568 since it allocates it for each state, although only one is needed.
10569 (allocate_storage): Do it here.
10570
10571 2001-12-29 Akim Demaille <akim@epita.fr>
10572
10573 * src/options.h, src/options.c (create_long_option_table): Rename
10574 as...
10575 (long_option_table_new): this, with a clearer prototype.
10576 (percent_table): Remove, unused,
10577 * src/getargs.c (getargs): Adjust.
10578
10579 2001-12-29 Akim Demaille <akim@epita.fr>
10580
10581 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
10582 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
10583 as states.
10584
10585 2001-12-29 Akim Demaille <akim@epita.fr>
10586
10587 * src/lalr.c (build_relations): Rename `states' as `states1'.
10588 Sorry, I don't understand exactly what it is, no better name...
10589
10590 2001-12-29 Akim Demaille <akim@epita.fr>
10591
10592 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
10593 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
10594 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
10595 as rules.
10596
10597 2001-12-29 Akim Demaille <akim@epita.fr>
10598
10599 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
10600 ago.
10601
10602 2001-12-29 Akim Demaille <akim@epita.fr>
10603
10604 * src/reader.c, src/reader.h (user_toknums): Remove.
10605 Adjust all users to use symbols[i]->user_token_number.
10606
10607 2001-12-29 Akim Demaille <akim@epita.fr>
10608
10609 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
10610 Adjust all users to use symbols[i]->prec or ->assoc.
10611
10612 2001-12-29 Akim Demaille <akim@epita.fr>
10613
10614 * src/reader.c, src/reader.h (tags): Remove.
10615 Adjust all users to use symbols[i]->tag.
10616
10617 2001-12-29 Akim Demaille <akim@epita.fr>
10618
10619 * src/gram.h, src/gram.c (symbols): New, similar to state_table
10620 and rule_table.
10621 * src/reader.c (packsymbols): Fill this table.
10622 Drop sprec.
10623 * src/conflicts.c (resolve_sr_conflict): Adjust.
10624 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
10625 single table.
10626 Use symbols[i]->tag instead of tags[i].
10627
10628 2001-12-29 Akim Demaille <akim@epita.fr>
10629
10630 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
10631 In addition, put a comment in there, to replace...
10632 * tests/regression.at (%union and C comments): Remove.
10633
10634 2001-12-29 Akim Demaille <akim@epita.fr>
10635
10636 * tests/regression.at (Web2c Actions): Blindly move the actual
10637 output as expected output. The contents *seem* right to me, but I
10638 can't pretend reading perfectly parser tables... Nonetheless, all
10639 the other tests pass correctly, the table look OK, even though the
10640 presence of `$axiom' is to be noted: AFAICS it is useless (but
10641 harmless).
10642
10643 2001-12-29 Akim Demaille <akim@epita.fr>
10644
10645 * src/reader.c (readgram): Don't add the rule 0 if there were no
10646 rules read. In other words, add it _after_ having performed
10647 grammar sanity checks.
10648 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
10649
10650 2001-12-29 Akim Demaille <akim@epita.fr>
10651
10652 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
10653 visible, and some states have now a different number.
10654
10655 2001-12-29 Akim Demaille <akim@epita.fr>
10656
10657 * src/reader.c (readgram): Bind the initial rule's lineno to that
10658 of the first rule.
10659 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
10660 (Solved SR Conflicts): Adjust rule 0's line number.
10661
10662 2001-12-29 Akim Demaille <akim@epita.fr>
10663
10664 Fix the `GAWK Grammar' failure.
10665
10666 * src/LR0.c (final_state): Initialize to -1 so that we do compute
10667 the reductions of the first state which was mistakenly confused
10668 with the final state because precisely final_state was initialized
10669 to 0.
10670 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
10671 now noticed by Bison.
10672 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
10673 have a reduction on $default.
10674
10675 2001-12-29 Akim Demaille <akim@epita.fr>
10676
10677 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
10678 rule line numbers.
10679 * src/closure.c (print_closure): Likewise.
10680 * src/derives.c (print_derives): Likewise.
10681 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
10682 now.
10683
10684 2001-12-29 Akim Demaille <akim@epita.fr>
10685
10686 * src/lalr.c (lookaheads_print): New.
10687 (lalr): Call it when --trace-flag.
10688 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
10689 are dumped.
10690
10691 2001-12-29 Akim Demaille <akim@epita.fr>
10692
10693 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
10694 when walking through ritem, even via rule->rhs.
10695 * src/reduce.c (dump_grammar, useful_production, reduce_output)
10696 (useful_production, useless_nonterminals): Likewise.
10697 (reduce_grammar_tables): Likewise, plus update nritems.
10698 * src/nullable.c (set_nullable): Likewise.
10699 * src/lalr.c (build_relations): Likewise.
10700 * tests/sets.at (Nullable): Adjust.
10701 Fortunately, now, the $axiom is no longer nullable.
10702
10703 2001-12-29 Akim Demaille <akim@epita.fr>
10704
10705 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
10706 the 0-sentinel.
10707 * src/gram.c (ritem_longest_rhs): Likewise.
10708 * src/reduce.c (nonterminals_reduce): Likewise.
10709 * src/print_graph.c (print_graph): Likewise.
10710 * src/output.c (output_rule_data): Likewise.
10711 * src/nullable.c (set_nullable): Likewise.
10712
10713 2001-12-29 Akim Demaille <akim@epita.fr>
10714
10715 * src/output.c: Comment changes.
10716
10717 2001-12-27 Paul Eggert <eggert@twinsun.com>
10718
10719 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
10720 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
10721 Sparc, as they were causing more porting problems than the
10722 (minor) performance improvement was worth.
10723
10724 Also, catch up with 1.31's YYSTD.
10725
10726 2001-12-27 Akim Demaille <akim@epita.fr>
10727
10728 * src/output.c (output_gram): Rely on nritems, not the
10729 0-sentinel. See below.
10730 Use -1 as separator, not 0.
10731 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
10732 Rely on -1 as separator in yyrhs, instead of 0.
10733 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
10734 twice `Now at end of input', therefore there are two lines less to
10735 expect.
10736
10737 2001-12-27 Akim Demaille <akim@epita.fr>
10738
10739 * tests/regression.at (Unresolved SR Conflicts):
10740 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
10741 below.
10742
10743 2001-12-27 Akim Demaille <akim@epita.fr>
10744
10745 * src/LR0.c (new_state): Recognize the final state by the fact it
10746 is reached by eoftoken.
10747 (insert_start_shifting_state, insert_eof_shifting_state)
10748 (insert_accepting_state, augment_automaton): Remove, since now
10749 these states are automatically computed from the initial state.
10750 (generate_states): Adjust.
10751 * src/print.c: When reporting a rule number to the user, substract
10752 1, so that the axiom rule is rule 0, and the first user rule is 1.
10753 * src/reduce.c: Likewise.
10754 * src/print_graph.c (print_core): For the time being, just as for
10755 the report, depend upon --trace-flags to dump the full set of
10756 items.
10757 * src/reader.c (readgram): Once the grammar read, insert the rule
10758 0: `$axiom: START-SYMBOL $'.
10759 * tests/set.at: Adjust: rule 0 is now displayed, and since the
10760 number of the states has changed (the final state is no longer
10761 necessarily the last), catch up.
10762
10763 2001-12-27 Akim Demaille <akim@epita.fr>
10764
10765 Try to make the use of the eoftoken valid. Given that its value
10766 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
10767 is used instead of > 0 where appropriate, (ii), depend upon nritems
10768 instead of the 0-sentinel.
10769
10770 * src/gram.h, src/gram.c (nritems): New.
10771 Expected to be duplication of nitems, but for the time being...
10772 * src/reader.c (packgram): Assert nritems and nitems are equal.
10773 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
10774 * src/closure.c (print_closure, print_fderives): Likewise.
10775 * src/gram.c (ritem_print): Likewise.
10776 * src/print.c (print_core, print_grammar): Likewise.
10777 * src/print_graph.c: Likewise.
10778
10779 2001-12-27 Akim Demaille <akim@epita.fr>
10780
10781 * src/main.c (main): If there are complains after grammar
10782 reductions, then output the report anyway if requested, then die.
10783 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
10784 * src/reader.c (eoftoken): New.
10785 (parse_token_decl): If the token being defined has value `0', it
10786 is the eoftoken.
10787 (packsymbols): No longer hack `tags' to insert `$' by hand.
10788 Be sure to preserve the value of the eoftoken.
10789 (reader): Make sure eoftoken is defined.
10790 Initialize nsyms to 0: now eoftoken is created just like the others.
10791 * src/print.c (print_grammar): Don't special case the eof token.
10792 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
10793 lie anyway, albeit pleasant.
10794 * tests/calc.at: Exercise error messages with eoftoken.
10795 Change the grammar so that empty input is invalid.
10796 Adjust expectations.
10797 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
10798
10799 2001-12-27 Akim Demaille <akim@epita.fr>
10800
10801 * configure.in: Check the protos of strchr ans strspn.
10802 Replace strchr if needed.
10803 * src/system.h: Provide the protos of strchr, strspn and memchr if
10804 missing.
10805 * lib/strchr.c: New.
10806 * src/reader.c (symbols_save): Use strchr.
10807
10808 2001-12-27 Akim Demaille <akim@epita.fr>
10809
10810 * src/print.c, src/print_graph.c (escape): New.
10811 Use it to quote the TAGS outputs.
10812 * src/print_graph.c (print_state): Now errors are in red, and
10813 reductions in green.
10814 Prefer high to wide: output the state number on a line of its own.
10815
10816 2001-12-27 Akim Demaille <akim@epita.fr>
10817
10818 * src/state.h, src/state.c (reductions_new): New.
10819 * src/LR0.c (set_state_table): Let all the states have a
10820 `reductions', even if reduced to 0.
10821 (save_reductions): Adjust.
10822 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
10823 * src/print.c (print_reductions, print_actions): Adjust.
10824 * src/output.c (action_row): Adjust.
10825
10826 2001-12-27 Akim Demaille <akim@epita.fr>
10827
10828 * src/state.h, src/state.c (errs_new, errs_dup): New.
10829 * src/LR0.c (set_state_table): Let all the states have an errs,
10830 even if reduced to 0.
10831 * src/print.c (print_errs, print_reductions): Adjust.
10832 * src/output.c (output_actions, action_row): Adjust.
10833 * src/conflicts.c (resolve_sr_conflict): Adjust.
10834
10835 2001-12-27 Akim Demaille <akim@epita.fr>
10836
10837 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
10838
10839 2001-12-27 Akim Demaille <akim@epita.fr>
10840
10841 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
10842 * src/print.c: here.
10843 (lookaheadset, shiftset): New, used as additional storage by
10844 print_reductions.
10845 (print_results): Adjust.
10846 (print_shifts, print_gotos, print_errs): New, extracted from...
10847 (print_actions): here.
10848 * src/print_graph.c (print_actions): Remove dead code.
10849
10850 2001-12-27 Akim Demaille <akim@epita.fr>
10851
10852 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
10853 `$n' and `@n'.
10854
10855 2001-12-27 Akim Demaille <akim@epita.fr>
10856
10857 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
10858 (build_relations): Adjust.
10859
10860 2001-12-27 Akim Demaille <akim@epita.fr>
10861
10862 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
10863 duplication.
10864
10865 2001-12-27 Akim Demaille <akim@epita.fr>
10866
10867 * src/reader.c (packgram): Catch nitems overflows.
10868
10869 2001-12-27 Akim Demaille <akim@epita.fr>
10870
10871 * src/files.c, src/files.h (guard_obstack): Remove.
10872 * src/output.c (output): Adjust.
10873 * src/reader.c (parse_braces): New, factoring...
10874 (copy_action, copy_guard): these two which are renamed as...
10875 (parse_action, parse_guard): these.
10876 As a voluntary consequence, using braces around guards is now
10877 mandatory.
10878
10879 2001-12-27 Akim Demaille <akim@epita.fr>
10880
10881 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
10882 * src/reader.c (symbol_list): `guard' and `guard_line' are new
10883 members.
10884 (symbol_list_new): Adjust.
10885 (copy_action): action_line is the first line, not the last.
10886 (copy_guard): Just as for actions, store the `action' only, not
10887 the switch/case/break flesh.
10888 Don't parse the user action that might follow the guard, let...
10889 (readgram): do it, i.e., now, there can be an action after a
10890 guard.
10891 In other words the guard is just explicitly optional.
10892 (packgram): Adjust.
10893 * src/output.c (guards_output): New.
10894 (output_parser): Call it when needed.
10895 (output): Also free the guard and attrs obstacks.
10896 * src/files.c, src/files.h (obstack_save): Remove.
10897 (output_files): Remove.
10898 As a result, if one needs the former `.act' file, using an
10899 appropriate skeleton which requires actions and guards is now
10900 required.
10901 * src/main.c (main): Adjust.
10902 * tests/semantic.at: New.
10903 * tests/regression.at: Use `input.y' as input file name.
10904 Avoid 8+3 problems by requiring input.c when the test needs the
10905 parser.
10906
10907 2001-12-27 Akim Demaille <akim@epita.fr>
10908
10909 * src/reader.c (symbol_list_new): Be sure to initialize all the
10910 fields.
10911
10912 2001-12-27 Akim Demaille <akim@epita.fr>
10913
10914 All the hacks using a final pseudo state are now useless.
10915
10916 * src/LR0.c (set_state_table): state_table holds exactly nstates.
10917 * src/lalr.c (nLA): New.
10918 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
10919 instead of lookaheadsp from the pseudo state (nstate + 1).
10920
10921 2001-12-27 Akim Demaille <akim@epita.fr>
10922
10923 * src/output.c (action_row, token_actions): Use a state_t instead
10924 of a integer, and nlookaheads instead of the following state's
10925 lookaheadsp.
10926
10927 2001-12-27 Akim Demaille <akim@epita.fr>
10928
10929 * src/conflicts.c (log_resolution, flush_shift)
10930 (resolve_sr_conflict, set_conflicts, solve_conflicts)
10931 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
10932 (conflicts_print, print_reductions): Use a state_t instead of an
10933 integer when referring to a state.
10934 As much as possible, depend upon nlookaheads, instead of the
10935 `lookaheadsp' member of the following state (since lookaheads of
10936 successive states are successive, the difference between state n + 1
10937 and n served as the number of lookaheads for state n).
10938 * src/lalr.c (add_lookback_edge): Likewise.
10939 * src/print.c (print_core, print_actions, print_state)
10940 (print_results): Likewise.
10941 * src/print_graph.c (print_core, print_actions, print_state)
10942 (print_graph): Likewise.
10943 * src/conflicts.h: Adjust.
10944
10945 2001-12-27 Akim Demaille <akim@epita.fr>
10946
10947 * src/bison.hairy: Formatting/comment changes.
10948 ANSIfy.
10949 Remove `register' indications.
10950 Add plenty of `static'.
10951
10952 2001-12-27 Akim Demaille <akim@epita.fr>
10953
10954 * src/output.c (prepare): Drop the muscle `ntbase' which
10955 duplicates ntokens.
10956 * src/bison.simple: Formatting/comment changes.
10957 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
10958 is an undocumented synonym.
10959
10960 2001-12-22 Akim Demaille <akim@epita.fr>
10961
10962 * src/output.c (output_table_data): Change the prototype to use
10963 `int' for array ranges: some invocations do pass an int, not a
10964 short.
10965 Reported by Wayne Green.
10966
10967 2001-12-22 Akim Demaille <akim@epita.fr>
10968
10969 Some actions of web2c.y are improperly triggered.
10970 Reported by Mike Castle.
10971
10972 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
10973 * tests/regression.at (Web2c): Rename as...
10974 (Web2c Report): this.
10975 (Web2c Actions): New.
10976
10977 2001-12-22 Akim Demaille <akim@epita.fr>
10978
10979 Reductions in web2c.y are improperly reported.
10980 Reported by Mike Castle.
10981
10982 * src/conflicts.c (print_reductions): Fix.
10983 * tests/regression.at (Web2c): New.
10984
10985 2001-12-18 Akim Demaille <akim@epita.fr>
10986
10987 Some host fail on `assert (!"foo")', which expands to
10988 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
10989 Reported by Nelson Beebee.
10990
10991 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
10992 `#define it_succeeded 0' and `assert (it_succeeded)'.
10993
10994 2001-12-17 Marc Autret <autret_m@epita.fr>
10995
10996 * src/bison.simple: Don't hard code the skeleton line and filename.
10997 * src/output.c (output_parser): Rename 'line' as 'output_line'.
10998 New line counter 'skeleton_line' (skeleton-line muscle).
10999
11000 2001-12-17 Paul Eggert <eggert@twinsun.com>
11001
11002 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
11003 YYDEBUG must be defined to a nonzero value.
11004
11005 * src/bison.simple (yytname): Do not assume that the user defines
11006 YYDEBUG to a properly parenthesized expression.
11007
11008 2001-12-17 Akim Demaille <akim@epita.fr>
11009
11010 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
11011 nlookaheads is a new member.
11012 Adjust all users.
11013 * src/lalr.h (nlookaheads): Remove this orphan declaration.
11014 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
11015 state.
11016
11017 2001-12-17 Akim Demaille <akim@epita.fr>
11018
11019 * src/files.h, src/files.c (open_files, close_files): Remove.
11020 * src/main.c (main): Don't open/close files, nor invoke lex_free,
11021 let...
11022 * src/reader.c (reader): Do it.
11023
11024 2001-12-17 Akim Demaille <akim@epita.fr>
11025
11026 * src/conflicts.c (print_reductions): Formatting changes.
11027
11028 2001-12-17 Akim Demaille <akim@epita.fr>
11029
11030 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
11031 (flush_reduce): New.
11032 (resolve_sr_conflict): Adjust.
11033
11034 2001-12-17 Akim Demaille <akim@epita.fr>
11035
11036 * src/output.c (output_obstack): Be static and rename as...
11037 (format_obstack): this, to avoid any confusion with files.c's
11038 output_obstack.
11039 * src/reader.h (muscle_obstack): Move to...
11040 * src/output.h: here, since it's defined in output.c.
11041
11042 2001-12-17 Akim Demaille <akim@epita.fr>
11043
11044 * src/output.c (action_row, save_column, default_goto)
11045 (sort_actions, matching_state, pack_vector): Better variable
11046 locality.
11047
11048 2001-12-17 Akim Demaille <akim@epita.fr>
11049
11050 * src/output.c: Various formatting changes.
11051
11052 2001-12-17 Akim Demaille <akim@epita.fr>
11053
11054 * src/files.c (output_files): Free the output_obstack.
11055 * src/main.c (main): Call print and print_graph conditionally.
11056 * src/print.c (print): Work unconditionally.
11057 * src/print_graph.c (print_graph): Work unconditionally.
11058 * src/conflicts.c (log_resolution): Output only if verbose_flag.
11059
11060 2001-12-16 Marc Autret <autret_m@epita.fr>
11061
11062 * src/output.c (actions_output): Fix. When we use %no-lines,
11063 there is one less line per action.
11064
11065 2001-12-16 Marc Autret <autret_m@epita.fr>
11066
11067 * src/bison.simple: Remove a useless #line directive.
11068 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
11069 * src/output.c (get_lines_number): New.
11070 (output_parser): Adjust, now takes care about the lines of a
11071 output muscles.
11072 Fix line numbering.
11073 (actions_output): Computes the number of lines taken by actions.
11074 (output_master_parser): Insert new skeleton which is the name of
11075 the output parser file name.
11076
11077 2001-12-15 Marc Autret <autret_m@epita.fr>
11078
11079 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
11080
11081 2001-12-15 Marc Autret <autret_m@epita.fr>
11082
11083 * src/output.c (output_gram): Keep track of the hairy one.
11084
11085 2001-12-15 Akim Demaille <akim@epita.fr>
11086
11087 Make `make distcheck' work.
11088
11089 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
11090 system.h which uses libgettext.h.
11091
11092 2001-12-15 Akim Demaille <akim@epita.fr>
11093
11094 * src/nullable.c (set_nullable): Useless rules must be skipped,
11095 otherwise, since we range over their symbols, we might look at a
11096 nonterminal which no longer ``exists'', i.e., it is not counted in
11097 `nvars', hence we overflow our arrays.
11098
11099 2001-12-15 Akim Demaille <akim@epita.fr>
11100
11101 The header can also be produced directly, without any obstack!
11102 Yahoo!
11103
11104 * src/files.c, src/files.h (defines_obstack): Remove.
11105 (compute_header_macro): Global.
11106 (defines_obstack_save): Remove.
11107 * src/reader.c (parse_union_decl): No longer output to
11108 defines_obstack: its content can be found in the `stype' muscle
11109 anyway.
11110 (output_token_translations): Merge into...
11111 (symbols_output): this.
11112 Rename as...
11113 (symbols_save): this.
11114 (reader): Adjust.
11115 * src/output.c (header_output): New.
11116 (output): Call it.
11117
11118 2001-12-15 Akim Demaille <akim@epita.fr>
11119
11120 * src/reader.c (parse_union_decl): Instead of handling two obstack
11121 simultaneously, use one to define the `stype' muscle, and use the
11122 value of the latter to fill defines_obstack.
11123 (copy_comment): Remove.
11124 (copy_comment2): Work for a single obstack.
11125 Rename as...
11126 (copy_comment): this.
11127
11128 2001-12-15 Akim Demaille <akim@epita.fr>
11129
11130 * src/lex.c, src/lex.h (xgetc): No longer static.
11131 * src/reader.c (parse_union_decl): Revamp.
11132
11133 2001-12-15 Akim Demaille <akim@epita.fr>
11134
11135 Still making progress in separating Bison into (i) input, (ii)
11136 process, (iii) output: now we can directly output the parser file
11137 without using table_obstack at all.
11138
11139 * src/files.c, src/files.h (table_obstack): Bye bye.
11140 (parser_file_name): New.
11141 * src/files.c (compute_output_file_names): Compute it.
11142 * src/output.c (actions_output, output_parser)
11143 (output_master_parser): To a file instead of an obstack.
11144
11145 2001-12-15 Akim Demaille <akim@epita.fr>
11146
11147 Attach actions to rules, instead of pre-outputting them to
11148 actions_obstack.
11149
11150 * src/gram.h (rule_t): action and action_line are new members.
11151 * src/reader.c (symbol_list): Likewise.
11152 (copy_action): Save the actions within the rule.
11153 (packgram): Save them in rule_table.
11154 * src/output.c (actions_output): New.
11155 (output_parser): Use it on `%%actions'.
11156 (output_rule_data): Don't free rule_table.
11157 (output): Do it.
11158 (prepare): Don't save the `action' muscle.
11159 * src/bison.simple: s/%%action/%%actions/.
11160
11161 2001-12-15 Akim Demaille <akim@epita.fr>
11162
11163 * src/reader.c (copy_action): When --yacc, don't append a `;'
11164 to the user action: let it fail if lacking.
11165 Suggested by Arnold Robbins and Tom Tromey.
11166
11167 2001-12-14 Akim Demaille <akim@epita.fr>
11168
11169 * src/lex.c (literalchar): Simply return the char you decoded, non
11170 longer mess around with obstacks and int pointers.
11171 Adjust all callers.
11172
11173 2001-12-14 Akim Demaille <akim@epita.fr>
11174
11175 * src/lex.c (literalchar): Don't escape the special characters,
11176 just decode them, and keep them as char (before, eol was output as
11177 the 2 char string `\n' etc.).
11178 * src/output.c (output_rule_data): Use quotearg to output the
11179 token strings.
11180
11181 2001-12-13 Paul Eggert <eggert@twinsun.com>
11182
11183 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
11184 Do not infringe on the global user namespace when using C++.
11185 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
11186 All uses of `fprintf' and `stderr' changed.
11187
11188 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
11189
11190 2001-12-13 Akim Demaille <akim@epita.fr>
11191
11192 The computation of nullable is broken: it doesn't handle empty
11193 RHS's properly.
11194
11195 * tests/torture.at (GNU AWK Grammar): New.
11196 * tests/sets.at (Nullable): New.
11197 * src/nullable.c (set_nullable): Instead of blindly looping over
11198 `ritems', loop over the rules, and then over their rhs's.
11199
11200 Work around Autotest bugs.
11201
11202 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
11203 frame, because Autotest understand lines starting with a `+' as
11204 traces from the shell. Then, they are not processed properly.
11205 Admittedly an Autotest bug, but we don't have time to wait for
11206 Autotest to catch up.
11207 * tests/regression.at (Broken Closure): Adjust to the new table
11208 frames.
11209 Move to...
11210 * tests/sets.at: here.
11211
11212 2001-12-13 Akim Demaille <akim@epita.fr>
11213
11214 * src/closure.c (closure): Use nrules instead of playing tricks
11215 with BITS_PER_WORD.
11216
11217 2001-12-13 Akim Demaille <akim@epita.fr>
11218
11219 * src/print.c (print_actions): Output the handling of `$' as the
11220 traces do: shifting the token EOF. Before EOF was treated as a
11221 nonterminal.
11222 * tests/regression.at: Adjust some tests.
11223 * src/print_graph.c (print_core): Complete the set of items via
11224 closure. The next-to-final and final states are still unsatisfying,
11225 but that's to be addressed elsewhere.
11226 No longer output the rule numbers, but do output the state number.
11227 A single loop for the shifts + gotos is enough, but picked a
11228 distinct color for each.
11229 (print_graph): Initialize and finalize closure.
11230
11231 2001-12-13 Akim Demaille <akim@epita.fr>
11232
11233 * src/reader.c (readgram): Remove dead code, an strip useless
11234 braces.
11235 (get_type): Remove, unused.
11236
11237 2001-12-12 Akim Demaille <akim@epita.fr>
11238
11239 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
11240 on that of lib/error.c.
11241
11242 2001-12-12 Akim Demaille <akim@epita.fr>
11243
11244 Some hosts don't like `/' in includes.
11245
11246 * src/system.h: Include libgettext.h without qualifying the path.
11247 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
11248 $(top_srcdir).
11249
11250 2001-12-11 Marc Autret <autret_m@epita.fr>
11251
11252 * src/output.c (output_parser): Remove useless muscle.
11253
11254 2001-12-11 Marc Autret <autret_m@epita.fr>
11255
11256 * src/bison.simple: Remove #line just before %%epilogue. It
11257 is now handled in ...
11258 * src/reader.c (read_additionnal_code): Add the output of a
11259 #line for the epilogue.
11260
11261 2001-12-10 Marc Autret <autret_m@epita.fr>
11262
11263 * src/reader.c (copy_definition): Re-use CPP-outed code which
11264 replace precedent remove.
11265 * src/bison.simple: Remove #line before %%prologue because
11266 %%input-line is wrong at this time.
11267
11268 2001-12-10 Marc Autret <autret_m@epita.fr>
11269
11270 * src/reader.c (symbols_output): Clean up.
11271 * src/output.c (output_gram, output): Clean up.
11272
11273 2001-12-10 Akim Demaille <akim@epita.fr>
11274
11275 * src/lalr.c (initialize_lookaheads): New. Extracted from...
11276 * src/LR0.c (set_state_table): here.
11277 * src/lalr.c (lalr): Call it.
11278
11279 2001-12-10 Akim Demaille <akim@epita.fr>
11280
11281 * src/state.h (shifts): Remove the `number' member: shifts are
11282 attached to state, hence no longer need to be labelled with a
11283 state number.
11284
11285 2001-12-10 Akim Demaille <akim@epita.fr>
11286
11287 Now that states have a complete set of members, the linked list of
11288 shifts is useless: just fill directly the state's shifts member.
11289
11290 * src/state.h (shifts): Remove the `next' member.
11291 * src/LR0.c (first_state, last_state): Remove.
11292 Adjust the callers.
11293 (augment_automaton): Don't look for the shifts that must be added
11294 a shift on EOF: it is those of the state we looked for! But now,
11295 since shifts are attached, it is no longer needed to looking
11296 merely by its id: its number.
11297
11298 2001-12-10 Akim Demaille <akim@epita.fr>
11299
11300 * src/LR0.c (augment_automaton): Better variable locality.
11301 Remove an impossible branch: if there is a state corresponding to
11302 the start symbol being shifted, then there is shift for the start
11303 symbol from the initial state.
11304
11305 2001-12-10 Akim Demaille <akim@epita.fr>
11306
11307 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
11308 only when appropriate: when insert_start_shifting_state' is not
11309 invoked.
11310 * tests/regression.at (Rule Line Numbers): Adjust.
11311
11312 2001-12-10 Akim Demaille <akim@epita.fr>
11313
11314 * src/LR0.c (augment_automaton): Now that all states have shifts,
11315 merge the two cases addition shifts to the initial state.
11316
11317 2001-12-10 Akim Demaille <akim@epita.fr>
11318
11319 * src/lalr.c (set_state_table): Move to...
11320 * src/LR0.c: here.
11321 * src/lalr.c (lalr): Don't call it...
11322 * src/LR0.c (generate_states): do it.
11323 * src/LR0.h (first_state): Remove, only the table is used.
11324
11325 2001-12-10 Akim Demaille <akim@epita.fr>
11326
11327 * src/LR0.h (first_shift, first_reduction): Remove.
11328 * src/lalr.c: Don't use first_shift: find shifts through the
11329 states.
11330
11331 2001-12-10 Akim Demaille <akim@epita.fr>
11332
11333 * src/LR0.c: Attach shifts to states as soon as they are
11334 computed.
11335 * src/lalr.c (set_state_table): Instead of assigning shifts to
11336 state, just assert that the mapping was properly done.
11337
11338 2001-12-10 Akim Demaille <akim@epita.fr>
11339
11340 * src/LR0.c (insert_start_shift): Rename as...
11341 (insert_start_shifting_state): this.
11342 (insert_eof_shifting_state, insert_accepting_state): New.
11343 (augment_automaton): Adjust.
11344 Better locality of the variables.
11345 When looking if the start_symbol is shifted from the initial
11346 state, using `while (... symbol != start_symbol ...)' sounds
11347 better than `while (... symbol < start_symbol ...)': If fail
11348 to see how the order between symbols could be relevant!
11349
11350 2001-12-10 Akim Demaille <akim@epita.fr>
11351
11352 * src/getargs.h: Don't declare `spec_name_prefix' and
11353 `spec_file_prefix', declared by src/files.h.
11354 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
11355 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
11356 * src/output.c (prepare): Adjust.
11357 * src/reader.c (symbols_output): Likewise.
11358 * src/vmsgetargs.c: Vaguely adjust, but who cares?
11359
11360 2001-12-10 Akim Demaille <akim@epita.fr>
11361
11362 * src/muscle_tab.c (muscle_init): NULL is a better default than
11363 `"0"'.
11364
11365 2001-12-10 Akim Demaille <akim@epita.fr>
11366
11367 * src/reader.c (reader): Calling symbols_output once is enough.
11368
11369 2001-12-10 Akim Demaille <akim@epita.fr>
11370
11371 Now that states have a complete set of members, the linked list of
11372 reductions is useless: just fill directly the state's reductions
11373 member.
11374
11375 * src/state.h (struct reductions): Remove member `number' and
11376 `next'.
11377 * src/LR0.c (first_reduction, last_reduction): Remove.
11378 (save_reductions): Don't link the new reductions, store them in
11379 this_state.
11380 * src/lalr.c (set_state_table): No need to attach reductions to
11381 states, it's already done.
11382 * src/output.c (output_actions): No longer free the shifts, then
11383 the reductions, then the states: free all the states and their

11386 2001-12-10 Akim Demaille <akim@epita.fr>
11387
11388 * src/options.c (OPTN, DRTV, BOTH): New.
11389 (option_table): Use them.
11390
11391 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
11392 the job of system.h.
11393 * src/options.c: Don't include stdio.h and xalloc.h for the same
11394 reasons.
11395
11396 2001-12-10 Akim Demaille <akim@epita.fr>
11397
11398 * src/output.c (output, prepare): Make sure the values of the
11399 muscles `action' and `prologue' are 0-terminated.
11400
11401 2001-12-10 Akim Demaille <akim@epita.fr>
11402
11403 Clean up GCC warnings.
11404
11405 * src/reader.c (copy_action): `buf' is not used.
11406 (parse_skel_decl): Be static.
11407 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
11408 * src/options.h (create_long_option_table): Have a real prototype.
11409 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
11410 (hash_delete_at): Return const void *.
11411 Adjust casts to preserve the const.
11412
11413 2001-12-10 Akim Demaille <akim@epita.fr>
11414
11415 * configure.in: Require 2.52g.
11416 M4 is not needed, but AUTOM4TE is.
11417 * m4/m4.m4: Remove.
11418 * tests/Makefile.am: Adjust.
11419
11420 2001-12-10 Akim Demaille <akim@epita.fr>
11421
11422 One structure for states is enough, even though theoretically
11423 there are LR(0) states and LALR(1) states.
11424
11425 * src/lalr.h (state_t): Remove.
11426 (state_table): Be state_t **, not state_t *.
11427 * src/state.h (core, CORE_ALLOC): Rename as...
11428 (state_t, STATE_ALLOC): this.
11429 Add the LALR(1) members: shifts, reductions, errs.
11430 * src/LR0.c (state_table): Rename as...
11431 (state_hash): this, to avoid name clashes with the global
11432 `state_table'.
11433 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
11434 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
11435
11436 2001-12-10 Akim Demaille <akim@epita.fr>
11437
11438 Bison dumps core on bash.y.
11439 Reported by Pascal Bart.
11440
11441 * src/warshall.c (bitmatrix_print): New.
11442 (TC): Use it.
11443 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
11444 j must be the outer loop.
11445 * tests/regression.at (Broken Closure): New.
11446
11447 2001-12-05 Akim Demaille <akim@epita.fr>
11448
11449 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
11450 its argument.
11451 Reported by Peter Hamorsky.
11452

11455 * src/conflicts.c (err_table): Remove.
11456 (resolve_sr_conflict): Adjust.
11457 * src/lalr.h (state_t.reduction_table, state_t.shift_table):

11459 (state_t.reductions, state_t.shifts): this.
11460
11461 2001-12-05 Akim Demaille <akim@epita.fr>
11462
11463 * src/reduce.c (reduce_grammar_tables): No longer disable the
11464 removal of useless rules via CPP but via `if (0)', so that the
11465 compiler still check the code is valid.
11466 For instance, it should have noticed `rline' no longer exists: use
11467 the `line' member of rule_t.
11468 * src/gram.c (dummy, rline): Remove, unused.
11469
11470 2001-12-05 Akim Demaille <akim@epita.fr>
11471
11472 * src/output.c (pack_vector): Use assert, not berror.
11473 * src/main.c (berror): Remove, unused.
11474
11475 2001-12-05 Akim Demaille <akim@epita.fr>
11476
11477 New experimental feature: if --verbose --trace output all the
11478 items of a state, not only its kernel.
11479
11480 * src/print.c (print_core): If `trace_flag', then invoke closure
11481 before outputting the items of the state (print_core is no longer
11482 a correct name them).
11483 (print_results): Invoke new_closure/free_closure if needed.
11484
11485 2001-12-05 Akim Demaille <akim@epita.fr>
11486
11487 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
11488 * src/closure.c, src/closure.h (itemsetsize): Rename as...
11489 (nitemset): for consistency with the rest of the project.
11490
11491 2001-12-05 Akim Demaille <akim@epita.fr>
11492
11493 * src/closure.c (print_closure): Improve.
11494 (closure): Use it for printing input and output.
11495
11496 2001-12-05 Akim Demaille <akim@epita.fr>
11497
11498 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
11499 indexed by nonterminals.
11500
11501 2001-12-05 Akim Demaille <akim@epita.fr>
11502
11503 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
11504 what it was!).
11505 * src/warshall.h: Remove accidental duplication of the content.
11506
11507 2001-12-05 Akim Demaille <akim@epita.fr>

11513 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
11514
11515 2001-12-05 Akim Demaille <akim@epita.fr>
11516
11517 * src/closure.c (set_firsts): De-obfuscate.
11518
11519 2001-12-05 Akim Demaille <akim@epita.fr>
11520
11521 * src/output.c (action_row): De-obfuscate
11522 using the good o' techniques: arrays not pointers, variable
11523 locality, BITISSET, RESETBIT etc.
11524
11525 2001-12-05 Akim Demaille <akim@epita.fr>
11526
11527 Pessimize the code to simplify it: from now on, all the states
11528 have a valid SHIFTS, which NSHIFTS is possibly 0.
11529
11530 * src/LR0.c (shifts_new): Be global and move to..
11531 * src/state.c, src/state.h: here.
11532 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
11533 * src/print_graph: Adjust.
11534
11535 2001-12-05 Akim Demaille <akim@epita.fr>
11536
11537 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
11538 * src/conflicts.c: Use it.
11539 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
11540 incorrectly ``simplified''.
11541
11542 2001-12-05 Akim Demaille <akim@epita.fr>
11543
11544 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
11545 using the good o' techniques: arrays not pointers, variable
11546 locality, BITISSET, RESETBIT etc.
11547
11548 2001-12-05 Akim Demaille <akim@epita.fr>
11549
11550 * src/state.h (SHIFT_SYMBOL): New.

11552
11553 2001-12-05 Akim Demaille <akim@epita.fr>
11554
11555 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
11556 (print_reductions): De-obfuscate using the good o' techniques:
11557 arrays not pointers, variable locality, BITISSET.
11558
11559 2001-12-05 Akim Demaille <akim@epita.fr>
11560
11561 * src/conflicts.c (print_reductions): Arrays, not pointers.
11562 Use BITISSET.
11563
11564 2001-12-05 Akim Demaille <akim@epita.fr>
11565
11566 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11567
11568 2001-12-05 Akim Demaille <akim@epita.fr>
11569
11570 * src/conflicts.c (print_reductions): Improve variable locality.
11571
11572 2001-12-05 Akim Demaille <akim@epita.fr>
11573
11574 * src/conflicts.c (print_reductions): Pessimize, but clarify.
11575
11576 2001-12-05 Akim Demaille <akim@epita.fr>
11577

11579
11580 2001-12-05 Akim Demaille <akim@epita.fr>
11581
11582 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
11583 * src/lalr.c: Use them.
11584
11585 2001-12-05 Akim Demaille <akim@epita.fr>
11586
11587 * src/LR0.c (augment_automaton): Formatting changes.
11588 Better variable locality.
11589
11590 2001-12-05 Akim Demaille <akim@epita.fr>
11591
11592 * src/lalr.c (matrix_print): New.
11593 (transpose): Use it.
11594 Use arrays instead of pointers.
11595
11596 2001-12-05 Akim Demaille <akim@epita.fr>
11597
11598 * src/lalr.c (maxrhs): Move to...
11599 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
11600 * src/lalr.c (build_relations): Adjust.
11601
11602 2001-12-05 Akim Demaille <akim@epita.fr>
11603
11604 * src/lalr.c (transpose): Free the memory allocated to the
11605 argument, as it is replaced by the results by the unique caller.
11606 (build_relations): Merely invoke transpose: it handles the memory
11607 deallocation.
11608 Improve variable locality.
11609 Avoid variables used as mere abbreviations.
11610 (compute_lookaheads): Use arrays instead of pointers.
11611
11612 2001-12-05 Akim Demaille <akim@epita.fr>
11613
11614 * src/lalr.c (initialize_F): Improve variable locality.
11615 Avoid variables used as mere abbreviations.
11616
11617 2001-12-05 Akim Demaille <akim@epita.fr>
11618
11619 * src/derives.c (print_derives): Display the ruleno.
11620 * src/lalr.c (initialize_F, transpose): Better variable locality
11621 to improve readability.
11622 Avoid variables used as mere abbreviations.
11623
11624 2001-12-05 Akim Demaille <akim@epita.fr>
11625
11626 * src/lalr.c (traverse): Use arrays instead of pointers.
11627
11628 2001-12-05 Akim Demaille <akim@epita.fr>
11629
11630 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
11631 the handling of squeue.
11632 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11633
11634 2001-12-05 Akim Demaille <akim@epita.fr>
11635
11636 Because useless nonterminals are now kept alive (instead of being
11637 `destroyed'), we now sometimes examine them, and store information
11638 related to them. Hence we need to know their number, and adjust
11639 memory allocations.
11640
11641 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
11642 static.
11643 * src/LR0.c (allocate_itemsets): The memory allocated to
11644 `symbol_count' was used for two different purpose: once to count
11645 the number of occurrences of each symbol, and later reassigned to
11646 `shift_symbol', containing the symbol that can be shifted from a
11647 given state.
11648 Deobfuscate, i.e., allocate, use and free `symbol_count' here
11649 only, and...
11650 (new_itemsets): Allocate `shift_symbol' here.
11651 (allocate_itemsets): symbol_count includes useless nonterminals.
11652 Make room for them.
11653 (free_storage): Use `free', not `XFREE', for pointers that cannot
11654 be null.
11655
11656 2001-12-05 Akim Demaille <akim@epita.fr>
11657
11658 * src/nullable.c (set_nullable): Deobfuscate the handling of
11659 ritem.
11660 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
11661
11662 2001-12-05 Akim Demaille <akim@epita.fr>
11663
11664 * src/gram.c, src/gram.h (ritem_print): New.
11665 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
11666 (This useless function was defined only to work around VMS linkers
11667 that can't handle compilation units with variables only).
11668 * src/reduce.c (dump_grammar): Use it to trace the construction of
11669 ritem.
11670
11671 2001-12-04 Paul Eggert <eggert@twinsun.com>
11672
11673 * src/bison.simple (union yyalloc): Change member names
11674 to be the same as the stack names.
11675 (yyparse): yyptr is now union yyalloc *, not char *.
11676 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
11677 and may generate better code on some machines.
11678 (yystpcpy): Use prototype if __STDC__ is defined, not just
11679 if __cplusplus is defined.
11680
11681 2001-11-30 Akim Demaille <akim@epita.fr>
11682
11683 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
11684 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
11685 Gettext doesn't compile cleanly, and dies with -Werror.
11686 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
11687 Include WARNING_CFLAGS here.
11688 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
11689 before being defined.
11690
11691 2001-11-27 Paul Eggert <eggert@twinsun.com>
11692
11693 * lib/quotearg.h (quotearg_n, quotearg_n_style):
11694 First arg is int, not unsigned.
11695 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
11696 (SIZE_MAX, UINT_MAX): New macros.
11697 (quotearg_n_options): Abort if N is negative.
11698 Avoid overflow check on hosts where size_t is 64 bits and int
11699 is 32 bits, as overflow is impossible there.
11700 Fix off-by-one typo that caused unnecessary reallocation.
11701
11702 2001-11-29 Paul Eggert <eggert@twinsun.com>
11703
11704 Name space cleanup in generated parser.
11705
11706 * doc/bison.texinfo (Bison Parser): Discuss system headers
11707 and their effect on the user name space.
11708
11709 * src/bison.simple:
11710 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
11711 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
11712 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
11713
11714 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
11715 on user names when possible.
11716
11717 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
11718 Simplify test for whather <alloca.h> exists.
11719
11720 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
11721
11722 (<stdio.h>): Include if YYDEBUG.
11723
11724 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
11725 ! defined (yyoverflow) && ! defined (yymemcpy).
11726
11727 (yymemcpy, yyparse): Rename local variables as needed so that
11728 they all begin with 'yy'.
11729
11730 (yystrlen, yystpcpy): New functions.
11731
11732 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
11733 All uses changed.
11734
11735 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
11736 instead of relying on string.h functions. Use YYSTACK_ALLOC
11737 and YYSTACK_FREE instead of malloc and free.
11738
11739 2001-11-30 Akim Demaille <akim@epita.fr>
11740
11741 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
11742 before their first uses.
11743 (YYBISON, YYPURE): Move to the top of the output.
11744
11745 2001-11-30 Akim Demaille <akim@epita.fr>
11746
11747 * tests/reduce.at (Useless Nonterminals): Fix.
11748
11749 2001-11-30 Akim Demaille <akim@epita.fr>
11750
11751 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
11752 if body instead of `;' to pacify GCC's warnings.
11753
11754 2001-11-30 Akim Demaille <akim@epita.fr>
11755
11756 Instead of mapping the LHS of unused rules to -1, keep the LHS
11757 valid, but flag the rules as invalid.
11758
11759 * src/gram.h (rule_t): `useful' is a new member.
11760 * src/print.c (print_grammar): Adjust.
11761 * src/derives.c (set_derives): Likewise.
11762 * src/reader.c (packgram, reduce_output): Likewise.
11763 * src/reduce.c (reduce_grammar_tables): Likewise.
11764 * tests/reduce.at (Underivable Rules, Useless Rules): New.
11765
11766 2001-11-30 Akim Demaille <akim@epita.fr>
11767
11768 * src/reduce.c (reduce_output): Formatting changes.
11769 * src/print.c (print_results, print_grammar): Likewise.
11770 * tests/regression.at (Rule Line Numbers)
11771 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
11772
11773 2001-11-30 Akim Demaille <akim@epita.fr>
11774
11775 * src/reduce.c (nonterminals_reduce): Instead of throwing away
11776 useless nonterminals, move them at the end of the symbol arrays.
11777 (reduce_output): Adjust.
11778 * tests/reduce.at (Useless Nonterminals): Adjust.
11779
11780 2001-11-30 Akim Demaille <akim@epita.fr>
11781
11782 * src/reduce.c: Various comment/formatting changes.
11783 (nonterminals_reduce): New, extracted from...
11784 (reduce_grammar_tables): here.
11785 (reduce_grammar): Call nonterminals_reduce.
11786
11787 2001-11-29 Paul Eggert <eggert@twinsun.com>
11788
11789 * src/bison.simple (YYSTACK_REALLOC): Remove.
11790 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
11791 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
11792 New macros.
11793 (union yyalloc): New type.
11794 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
11795 an arbitrary restriction on hosts where size_t is wider than int.
11796
11797 (yyparse): Don't dump core if alloca or malloc fails; instead, report
11798 a parser stack overflow. Allocate just one block of memory for all
11799 three stacks, instead of allocating three blocks; this typically is
11800 faster and reduces fragmentation.
11801
11802 Do not limit the number of items in the stack to a value that fits
11803 in 'int', as this is an arbitrary limit on hosts with 64-bit
11804 size_t and 32-bit int.
11805
11806 2001-11-29 Marc Autret <autret_m@epita.fr>
11807
11808 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
11809 of defining YYERROR_VERBOSE.
11810 [AT_DATA]: $4 is now out of C declarations in the prologue.
11811
11812 2001-11-28 Marc Autret <autret_m@epita.fr>
11813

12232 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
12233 now the tests are run in private dirs, therefore AC_CLEANUP and

13191 obstack. It was done too late here.

13566
13567 * src/getargs.h (raw_flag): Remove.
13568 * src/getargs.c: Die on `-r'/`--raw'.
13569 * src/lex.c (parse_percent_token): Die on `%raw'.
13570 * src/reader.c (output_token_defines): Suppress call to `raw_flag'.
13571 * tests/calc.at: Suppress test with option `--raw'.
13572
13573 2001-07-14 Akim Demaille <akim@epita.fr>
13574

13578
13579 2001-03-16 Akim Demaille <akim@epita.fr>
13580
13581 * doc/bison.texinfo: ANSIfy the examples.

13583 2001-03-16 Akim Demaille <akim@epita.fr>
13584
13585 * getargs.c (skeleton): New variable.
13586 (longopts): --skeleton is a new option.
13587 (shortopts, getargs): -S is a new option.

13598
13599 * src/getargs.c (longopts): Clean up.
13600
13601 2001-02-21 Akim Demaille <akim@epita.fr>
13602
13603 * src/reader.c (gensym): `gensym_count' is your own.
13604 Use a static buf to create the symbol name, as token_buffer is no
13605 longer a buffer.

13608
13609 * src/conflicts.c (conflict_report): Be sure not to append to res
13610 between two calls, which could happen if both first sprintf were

13614
13615 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
13616 New, from fileutils 4.0.37.
13617 * configure.in: Require Autoconf 2.49c. I took some time before
13618 making this decision. This is the only way out for portability
13619 issues in Bison, it would mean way too much duplicate effort to
13620 import in Bison features implemented in 2.49c since 2.13.
13621 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
13622

13634 (init_lex): Initialize it. No longer call...
13635 (grow_token_buffer): this. Remove it.
13636 Adjust all the places which used it to use the obstack.
13637
13638 2001-01-19 Akim Demaille <akim@epita.fr>
13639
13640 * src/lex.h: Rename all the tokens:
13641 s/\bENDFILE\b/tok_eof/g;
13642 s/\bIDENTIFIER\b/tok_identifier/g;
13643 etc.
13644 Let them be enums, not #define, to ease debugging.
13645 Adjust all the code.
13646
13647 2001-01-18 Akim Demaille <akim@epita.fr>
13648

13651
13652 2001-01-18 Akim Demaille <akim@epita.fr>
13653
13654 Since we now use obstacks, more % directives can be enabled.
13655
13656 * src/lex.c (percent_table): Also accept `%yacc',
13657 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
13658 `%debug'.
13659 Handle the actions for `%semantic_parser' and `%pure_parser' here,
13660 instead of returning a token.
13661 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
13662 * src/reader.c (read_declarations): Adjust.
13663 * src/files.c (open_files): Don't call `compute_base_names', don't
13664 compute `attrsfile' since they depend upon data which might be
13665 *in* the input file now.
13666 (output_files): Do it here.
13667 * src/output.c (output_headers): Document the fact that this patch
13668 introduces a guaranteed SEGV for semantic parsers.
13669 * doc/bison.texinfo: Document them.
13670 * tests/suite.at: Exercise these %options.
13671

13690
13691 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

13693 FILE * parameters.
13694
13695 2000-12-20 Akim Demaille <akim@epita.fr>
13696
13697 * src/files.c (open_files): Actually the `.output' file is based
13698 on the short_base_name, not base_name.
13699 * tests/suite.at (Checking output file names): Adjust.
13700
13701 2000-12-20 Akim Demaille <akim@epita.fr>

13726 * src/files.c (strsuffix): New.
13727 (stringappend): Be just like strcat but allocate.
13728 (base_names): Eve out from open_files.
13729 Try to simplify the rather hairy computation of base_name and
13730 short_base_name.
13731 (open_files): Use it.
13732 * tests/suite.at (Checking output file names): New test.
13733
13734 2000-12-19 Akim Demaille <akim@epita.fr>

13750 2000-12-19 Akim Demaille <akim@epita.fr>
13751
13752 Let the handling of the skeleton files be local to the procedures

13770 2000-12-19 Akim Demaille <akim@epita.fr>
13771
13772 * src/files.c (open_files): Yipee! We no longer need all the code
13773 looking for `/tmp' since we have no tmp file.
13774
13775 2000-12-19 Akim Demaille <akim@epita.fr>
13776

13806 prevents type checking.
13807 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
13808 cast the value to (void *): assigning a `foo *' to a `void *'

13811 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

13855 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
13856 argument `data' for consistency with the prototypes.
13857 Qualify it `const'.
13858 (obstack_copy, obstack_copy0): Rename the second argument as

13999 When a literal string is used to define two different tokens,
14000 `bison -v' segfaults.
14001 Reported by Piotr Gackiewicz, and fixed by Neil Booth.

14011 of `buffer'.
14012 From Neil Booth.
14013
14014 2000-10-02 Paul Eggert <eggert@twinsun.com>
14015
14016 * bison.s1 (yyparse): Assign the default value
14017 unconditionally, to avoid a GCC warning and make the parser a
14018 tad smaller.
14019
14020 2000-10-02 Akim Demaille <akim@epita.fr>
14021
14022 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
14023 options.
14024
14025 2000-10-02 Akim Demaille <akim@epita.fr>
14026
14027 * src/derives.c, src/print.c, src/reduce.c: To ease the
14028 translation, move some `\n' out of the translated strings.
14029
14030 2000-10-02 Akim Demaille <akim@epita.fr>
14031
14032 The location tracking mechanism is precious for parse error
14033 messages. Nevertheless, it is enabled only when `@n' is used in
14034 the grammar, which is a different issue (you can use it in error
14035 message, but not in the grammar per se). Therefore, there should
14036 be another means to enable it.
14037
14038 * src/getargs.c (getargs): Support `--locations'.
14039 (usage): Report it.
14040 * src/getargs.h (locationsflag): Export it.
14041 * src/lex.c (percent_table): Support `%locations'.
14042 * src/reader.c (yylsp_needed): Remove this variable, now replaced
14043 with `locationsflag'.
14044 * doc/bison.texinfo: Document `--locations' and `%locations'.
14045 Sort the options.
14046 * tests/calc.m4: Test it.
14047
14048 For regularity of the names, replace each
14049 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
14050 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
14051 In addition replace each `flag' with `_flag'.
14052
14053 2000-10-02 Akim Demaille <akim@epita.fr>
14054
14055 Also test parse error messages, including with YYERROR_VERBOSE.
14056
14057 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
14058 associative).
14059 Use it to check the computations.
14060 Use it to check `nonassoc' is honored.
14061 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
14062 `--yyerror-verbose'.
14063 (_AT_CHECK_CALC): Adjust to this option.
14064 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
14065
14066 2000-10-02 Akim Demaille <akim@epita.fr>
14067
14068 Test also `--verbose', `--defines' and `--name-prefix'. Testing
14069 the latter demonstrates a flaw in the handling of non debugging
14070 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
14071 was used in order to simplify:
14072
14073 #if YYDEBUG
14074 if (yydebug)
14075 {
14076 ...
14077 }
14078 #endif
14079
14080 into
14081
14082 if (yydebug)
14083 {
14084 ...
14085 }
14086
14087 unfortunately this leads to a CPP conflict when
14088 `--name-prefix=foo' is used since it produces `#define yydebug
14089 foodebug'.
14090
14091 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
14092 (YYDPRINTF): New macro.
14093 Spread its use.
14094 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
14095 the bison options.
14096 Also test `--verbose', `--defines' and `--name-prefix'.
14097
14098 2000-10-02 Akim Demaille <akim@epita.fr>
14099
14100 Improve the readability of the produced parsers.
14101
14102 * src/bison.s1: Formatting changes.
14103 Improve the comment related to the `$' mark.
14104 (yydefault): Don't fall through to `yyresume': `goto' there.
14105 * src/output.c (output_parser): When the `$' is met, skip the end
14106 of its line.
14107 New variable, `number_of_dollar_signs', to check there's exactly
14108 one `$' in the parser skeleton.
14109
14110 2000-10-02 Akim Demaille <akim@epita.fr>
14111
14112 * lib/xstrdup.c: New file, from the fileutils.
14113 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
14114 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
14115 instead of strlen + xmalloc + strcpy.
14116 * src/symtab.c (copys): Remove, use xstrdup instead.
14117
14118 2000-10-02 Akim Demaille <akim@epita.fr>
14119
14120 * src/gram.h (associativity): New enum type which replaces the
14121 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
14122 `right_assoc', `left_assoc' and `non_assoc'.
14123 Adjust all dependencies.
14124 * src/reader.c: Formatting changes.
14125 (LTYPESTR): Don't define it, use it as a literal in
14126 `reader_output_yylsp'.
14127 * src/symtab.h (symbol_class): New enum type which replaces the
14128 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
14129 `sunknown', `stoken and `snterm'.
14130
14131 2000-10-02 Akim Demaille <akim@epita.fr>
14132
14133 * src/getargs.c (fixed_outfiles): Rename as...
14134 (yaccflag): for consistency and accuracy.
14135 Adjust dependencies.
14136
14137 2000-10-02 Akim Demaille <akim@epita.fr>
14138
14139 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
14140 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
14141 difficult and introduced a lot of core dump. It turns out that
14142 Bison used an implementation of `xmalloc' based on `calloc', and
14143 at various places it does depend upon the initialization to 0. I
14144 have not tried to isolate the pertinent places, and all the former
14145 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
14146 someone should address this issue.
14147
14148 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
14149 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

14194 Propagate its inclusion.
14195
14196 2000-10-02 Akim Demaille <akim@epita.fr>

14245 output_short_table.
14246
14247 2000-10-02 Akim Demaille <akim@epita.fr>
14248
14249 `user_toknums' is output as a `short[]' in `output.c', while it is
14250 defined as a `int[]' in `reader.c'. For consistency with the
14251 other output tables, `user_toknums' is now defined as a table of
14252 shorts.
14253
14254 * src/reader.c (user_toknums): Be a short table instead of an int
14255 table.

14294 Don't define PARAMS.
14295 * src/system.h: Define PARAMS.

14515
14516 Change the handling of @s so that they behave exactly like $s.
14517 There is now a pseudo variable @$ (readble and writable), location
14518 of the lhs of the rule (by default ranging from the location of
14519 the first symbol of the rhs, to the location of the last symbol,
14520 or, if the rhs is empty, YYLLOC).

14555 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
14556 One `#if YYDEBUG' remains, since it uses variables which are
14557 defined only if `YYDEBUG != 0'.
14558
14559 2000-03-16 Akim Demaille <akim@epita.fr>

15283 way to specify the flags -n, -l, and -r. Also added hooks for
