3 * NEWS: Version 2.0b.
4
5 Fix core dump reported by Pablo De Napoli in
6 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7 * tests/regression.at (Invalid inputs with {}): New test.
8 * src/parse-gram.y (token_name): Translate type before using
9 it as an index.
10
11 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
12 the user's name space. All uses changed to __attribute__
13 ((__unused__)).
14 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
15 Add __attribute__ ((__noreturn__)).
16
17 * etc/clcommit: Remove. We weren't using it, and it failed
18 "make maintainer-distcheck".

37 (my-distcheck): Use more-modern GCC flags.
38 (signatures, %.asc): Remove.
39 (rel-files, announcement): Remove signatures.
40 Restore old updating code, even though we don't use it, so
41 that we're the same as coreutils.
42 (alpha, beta, major): Depend on news-date-check.
43 Make the upload commands.
44
45 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
46 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
47 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
48 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
49 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
50 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
51 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
52 * tests/sets.at: Likewise.
53
54 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
55 we comment out the Autoconf version number.
56 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
57 it's error-prone and "make maintainer-distcheck" rejects it.
58
59 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
60 Indent calls to "error" to pacify "make maintainer-distcheck",
61 when the calls are not intended to be translated.
62 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
63
64 * src/Makefile.am (DEFS): Use +=, to pacify

67 (sc_tight_scope): New rule, from coreutils.
68
69 * src/files.c (src_extension, header_extension):

74 Likewise.
75 * src/reader.c (grammar_end, previous_rule_end): Likewise.
76 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
77 * src/main.c (main): Cast bindtextdomain and textdomain calls to
78 void, to avoid warning when NLS is disabled.
79 * src/output.c: Include scan-skel.h.
80 (scan_skel): Remove decl, since scan-skel.h does this.
81 (output_skeleton):
82 Indent calls to "error" to pacify "make maintainer-distcheck".
83 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
84 * src/reader.h (gram_end, gram_lineno): New decls to pacify
85 "make maintainer-distcheck".
86 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
87 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
88 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
89 (skel_lex_destroy, scan_skel): Move these decls to...
90 * src/scan-skel.h: New file.
91 * src/uniqstr.c (uniqstr_assert):
92 Indent calls to "error" to pacify "make maintainer-distcheck".
93
94 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
95 not @VAR@.
96
97 * tests/torture.at: Revamp to avoid misuse of atoi that
98 "make maintainer-distcheck" complained about.
99
100 * examples/extexi (message): Don't print a message more than once,
101 and omit line-number decoration that makes Emacs compile think
102 that informative messages are worth worrying about.
103
104 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
105
106 * configure.ac: Update version number.
107
108 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
109 accidentally.
110 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
111 autogenerated by the maintainer.
112 * examples/calc++/.cvsignore: Add *.yy.
113
114 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
115 * lib/bitset_stats.c (bitset_stats_init): Likewise.
116 * lib/bitsetv.c (bitsetv_alloc): Likewise.
117
118 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
119
120 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
121 from maintainer-distcheck about casting the argument of 'free'.
122
123 * NEWS: Mention recent yytname changes.
124 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
125
126 * bootstrap: For translations that have not yet been upgraded to
127 the new runtime-po domain, prime the pump by extracting the
128 relevant strings from the obsolete translations. This code can be
129 removed once the bison-runtime domain has been translated by each
130 team.
131
132 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
133 now that token names are already quoted.
134
135 Fix problem reported by Anthony Heading.
136 * data/glr.c (YYTOKEN_TABLE): New macro.
137 (yytname): Define if YYTOKEN_TABLE.
138 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
139 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
140 (YYERROR_VERBOSE): Define the same way the other skeletons do.
141 * src/output.c (prepare_symbols): Output token_table_flag.
142
143 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
144
145 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
146 again if the first call fails.
147
148 * data/glr.c (yytnamerr): New function.
149 (yyreportSyntaxError): Use it to dequote most string literals.
150 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
151 with other skeletons. All uses changed.
152 (yytnameerr_): New function.
153 (yyreport_syntax_error): Use it to dequote most string literals.
154 * data/yacc.c (yytnamerr): New function.
155 (yyerrlab): Use it to decode most string literals.
156 * doc/bison.texinfo (Decl Summary, Calling Convention):
157 Clarify quoting convention of yytname.
158 * src/output.c (prepare_symbols): Quote all names. This undoes
159 the 2005-04-17 change, which is now accomplished (mostly) via
160 changes in the parsers as described above.
161 * tests/regression.at (Token definitions, Web2c Actions):
162 Undo most 2005-04-17 change here, too.
163
164 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
165
166 Fix more problems reported by twlevo@xs4all.nl.
167 * tests/cxx-type.at: Don't pipe output of ./types through sed to
168 remove trailing spaces. This loses the exit status of ./types,
169 and isn't needed since ./types shouldn't be emitting trailing
170 spaces.
171 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
172 as the stack isn't valid in that case.
173
174 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
175 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
176 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
177 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
178 is used.
179 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
180 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
181 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
182 Likewise.
183
184 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
185 overly-picky compilers that reject 'char *foo = "bar";'.
186
187 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
188 to FILE * parameter, not to stderr. This fixes a typo introduced
189 in the 2005-07-12 change.
190
191 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
192 warnings from GCC 4.
193
194 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
195 (yyglrShiftDefer, yysplitStack):
196 Remove unused parameters b4_pure_formals. All uses changed.
197 (yyglrShift): Remove unused parameters b4_user_formals.
198 All uses changed.
199 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
200
201 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
202
203 Destructor cleanups and regularization among the three skeletons.
204 * NEWS: Document the behavior changes.
205 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
206 stack before failing, as the cleanup code will do it for us now.
207 * data/lalr1.cc (yyerrlab): Likewise.
208 * data/glr.c (yyparse): Pop everything off the stack before
209 freeing it, so that destructors get called properly.
210 * data/lalr1.cc (yyreturn): Likewise.
211 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
212 This is more consistent.
213 * doc/bison.texinfo (Destructor Decl): Mention more reasons
214 why destructors might be called. 1.875 -> 2.1.
215 (Destructor Decl, Decl Summary, Table of Symbols):
216 Some English-language cleanups for %destructor.
217 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
218 Add output line for destructor of start symbol.
219 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
220 because of that same extra output line.
221
222 * NEWS: Document minor wording changes in diagnostics of
223 Bison-generated parsers.
224 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
225 Remove unused formals. All uses changed.
226 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
227 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
228 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
229 Rename yyoverflowab to yyexhaustedlab.
230 When memory exhaustion occurs during syntax-error reporting,
231 report it separately rather than in a single diagnostic; this
232 eases translation.
233 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
234 (Memory Exhausted): Renamed from Parser Stack Overflow.
235 Revamp wording slightly to prefer "memory exhaustion".
236 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
237
238 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
239
240 Add i18n support to the GLR skeleton. Partially fix the C++
241 skeleton; a C++ expert needs to finish this. Remove debugging
242 msgids; there's little point to having them translated, since they
243 can be understood only by someone who can read the
244 (English-language) source code.
245
246 Generate runtime-po/bison-runtime.pot automatically, so that we
247 don't have to worry about garbage getting in that file. We'll
248 make sure after the next official release that old msgids don't
249 get lost. See
250 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
251
252 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
253 Now auto-generated.
254 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
255 Fix typos in explanations of the runtime file.
256 * bootstrap: Change gettext keyword from YYI18N to YY_.
257 Use standard Makefile.in.in in runtime-po, since we'll arrange
258 for backward-compatible bison-runtime.po files in a different way.
259 * data/glr.c (YY_): New macro, from yacc.c.
260 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
261 Translate messages intended for users.
262 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
263 the wording in the other skeletons. We don't know that the memory
264 is virtual.
265 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
266 Use same method that yacc.c uses.
267 Don't translate debugging messages.
268 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
269 it doesn't work (yet), and requires C++ expertise to fix.
270 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
271 Move defn to a more logical place, to be consistent with other
272 skeletons.
273 Don't translate debugging messages.
274 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
275 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
276 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
277 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
278
279 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
280 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
281 void, not int.
282 * tests/glr-regression.at (Badly Collapsed GLR States):
283 Likewise.
284 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
285 yylex should return 0 at EOF rather than aborting.
286
287 Improve tests for stack overflow in GLR parser.
288 Problem reported by twlevo@xs4all.nl.
289 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
290 All uses removed.
291 (yyStackOverflow): Just longjmp, but with value 2 so that caller
292 can handle the problem.
293 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
294 (yyparse): New local variable yyresult to record the result.
295 Use result of setjmp to set it, rather than storing itinto
296 struct.
297 (yyDone): Remove label.
298 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
299 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
300 if YYABORT is used).
301 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
302 yyparse status; put status > 1 into diagnostic.
303 Check that status==2 works.
304 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
305 Use exit status 3 for failure to open (which shouldn't happen).
306
307 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
308
309 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
310 1 on syntax error; just let yyparse do its thing.
311 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
312 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
313 (Exploding the Stack Size with Alloca):
314 (Exploding the Stack Size with Malloc):
315 Expect exit status 2, not 1, since the parser is supposed to blow
316 its stack. Problem reported by twlevo@xs4all.nl.
317
318 * data/glr.c (yyparse): Don't assume that the initial calls
319 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
320 Print a stack-overflow message and fail instead.
321 Initialize the line-number information before creating the stack,
322 so that the stack-overflow message can report line zero safely.
323
324 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
325
326 Fix problems reported by twlevo@xs4all.nl.
327 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
328 (yyuserMerge): Provide a default case if b4_mergers is empty.
329 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
330 * tests/glr-regression.at
331 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
332 Add casts to pacify C++ compilers.
333 * tests/glr-regression.at (Improper merging of GLR delayed action
334 sets): Declare yylex before using it.
335 * tests/Makefile.am (maintainer-check-g++): Fix a stray
336 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
337 test for valgrind; valgrind is independent of g++.
338 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
339 for compatibility with POSIX 1003.1-2001 (if running coreutils).
340 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
341 Use a destructor, so that we can expand the stack. Change
342 YYSTYPE to char * so that we can free it. Cast result of malloc.
343
344 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
345
346 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
347 a valgrind failure. Problem reported by twlevo@xs4all.nl.
348
349 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
350
351 * PACKAGING: New file, suggested by Bruno Haible and taken from
352 similar wording in gettext's PACKAGING file.
353 * NEWS: Mention PACKAGING.
354 * Makefile.am (EXTRA_DIST): Add PACKAGING.
355
356 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
357
358 * NEWS: Document recent i18n improvements.
359 * bootstrap: Get runtime translations into runtime-po.
360 Create runtime-po files automatically, if possible.
361 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
362 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
363 does not infringe on the user's name space.
364 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
365 * doc/bison.texinfo (Internationalization): Revamp the English
366 and Texinfo syntax a bit, to try to make it clearer.
367 (Bison Options, Option Cross Key): Mention --print-localedir.
368 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
369 YYENABLE_NLS. Quote a bit more.
370 * runtime-po/.cvsignore: New file.
371 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
372 * runtime-po/Rules-quot: Remove; now created by bootstrap.

377 * runtime-po/insert-header.sin: Likewise.
378 * runtime-po/remove-potcdate.sin: Likewise.
379 * runtime-po/Makevars: Likewise.
380 * runtime-po/LINGUAS: Likewise.
381 * runtime-po/de.po: Likewise; we will rely on the translation project
382 to maintain this, so "bootstrap" should get it.
383 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
384 its value.
385 * src/main.c (main): Bind the bison-runtime domain, too.
386
387 2005-07-12 Bruno Haible <bruno@clisp.org>
388
389 * data/yacc.c: Include <libintl.h> when NLS is enabled.
390 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
391 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
392 * runtime-po: New directory.
393 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
394 $(DOMAIN).pot-update rule, so that old messages are never dropped.
395 * runtime-po/Rules-quot: New file, copied from po/.
396 * runtime-po/quot.sed: Likewise.

411 Define aclocaldir.
412 * src/getargs.c (usage): Document --print-localedir option.
413 (PRINT_LOCALEDIR_OPTION): New enum item.
414 (long_options): Add --print-localedir option.
415 (getargs): Handle --print-localedir option.
416 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().

426 2005-07-12 Akim Demaille <akim@epita.fr>
427
428 * src/parse-gram.y: Use %printer instead of YYPRINT.
429
430 2005-07-12 Akim Demaille <akim@epita.fr>
431
432 * src/symtab.h, src/symtab.c (symbol_print): New.
433 * src/symlist.h, src/symlist.c (symbol_list_print): New.
434 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
435
436 2005-07-12 Akim Demaille <akim@epita.fr>
437
438 * data/glr.c (b4_syncline): Fix (swap) the definitions of
439 b4_at_dollar and b4_dollar_dollar.
440
441 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
442
443 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
444 and Pennello's paper.
445
446 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
447
448 * data/yacc.c (yyparse): Undo previous patch. Instead,
449 set yylsp[0] and yyvsp[0] only if the initial action
450 sets yylloc and yylval, respectively.
451
452 * data/yacc.c (yyparse): In the initial action, set
453 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
454 This avoids the use of undefined variables if the initial
455 action does not set yylloc and/or yylval.
456
457 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
458
459 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
460 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
461 Remove from CVS. These files are automatically generated.
462 * examples/extexi: Clarify that this file is now part of Bison,
463 not GNU M4, and that it works with any POSIX-compatible Awk.
464 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
465 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
466 so that we also get calc++-parser.yy. Geneate it.
467 Use $(AWK), not gawk, since any conforming Awk will do.
468 Put comment before action, since older 'make' can't handle comment
469 in action.
470 $(BUILT_SOURCES): List all built sources, not just some of them.
471 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
472 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
473 $($(calc_sources_generated)): Remove unnecessary test for existence
474 of target. (This had a shell syntax error anyway; a stray "x".)
475 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
476 calc++-parser.yy.
477 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
478
479 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
480 implied by the other modules.
481
482 2005-07-06 Akim Demaille <akim@epita.fr>
483
484 Bind examples/calc++ to the package.
485 * examples/calc++/Makefile: Remove, replaced by...
486 * examples/calc++/Makefile.am: ... this new file.
487 * examples/calc++/test: Remove input.
488 * examples/calc++/compile: Remove.
489 * examples/Makefile.am: New.
490 * configure.ac, Makefile.am: Adjust.
491 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
492
493 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
494
495 * data/glr.c (yyFail): Drastically simplify; since the format argument
496 never had any % directives, we can simply pass it to yyerror.
497 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
498 be modified later, as that is the usual style in glr.c.
499 Problems reported by Paul Hilfinger.
500
501 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
502 and size overflow errors.
503 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
504 in case the user prolog sets feature-test macros like _GNU_SOURCE.
505 (YYSIZEMAX): New macro.
506 (yystpcpy): New function, taken from yacc.c.
507 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
508 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
509 so that we don't have to maintain their signatures.
510 (yyFail): Check for buffer overflow, by using vsnprintf rather
511 than vsprintf. Allocate a bigger buffer if possible.
512 Report an error if buffer allocation fails.
513 (yyStackOverflow): New function.
514 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
515 the initialization was successful. It might fail if storage was
516 exhausted.
517 (yyexpandGLRStack): Add more checks for storage allocation failure.
518 Use yyStackOverflow to report failures.
519 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
520 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
521 Don't assume stack number fits in int.
522 (yysplitStack): Check for storage allocation failure.
523 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
524 can print diagnostics on storage allocation failure. All callers
525 changed.
526 (yyresolveValue): Use yybool for boolean.
527 (yyreportSyntaxError): Check for size-calculation overflow.
528 This code is taken from yacc.c.
529 (yyparse): Check for storage allocation errors when allocating
530 the initial stack.
531
532 2005-07-05 Akim Demaille <akim@epita.fr>
533
534 Extract calc++ from the documentation.
535 * doc/bison.texinfo (Calc++): Add the extraction marks.
536 * examples/extexi: New, from the aborted GNU Programming 2E.
537 Separate the different paragraph of a file with empty lines.
538 * examples/Makefile: Use it to extract the whole calc++ example.
539
540 2005-06-24 Akim Demaille <akim@epita.fr>
541
542 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
543 class typedefs.
544
545 2005-06-22 Akim Demaille <akim@epita.fr>
546
547 * doc/bison.texinfo (C++ Language Interface): First stab.
548 (C++ Parsers): Remove.
549
550 2005-06-22 Akim Demaille <akim@epita.fr>
551
552 * data/lalr1.cc (yylex_): Honor %lex-param.
553
554 2005-06-22 Akim Demaille <akim@epita.fr>
555
556 Start a set of simple examples.
557 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
558 * examples/calc++/calc++-driver.hh,
559 * examples/calc++/calc++-parser.yy,
560 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
561 * examples/calc++/compile, examples/calc++/test: New.
562
563 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
564
565 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
566 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
567 which stems from the 2005-05-27 patch.
568
569 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
570
571 * data/glr.c: Modify treatment of unused parameters to permit use
572 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
573
574 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
575
576 Fix infringement on user name space reported by Janos Zoltan Szabo.
577 * data/yacc.c (yyparse): strlen -> yystrlen.
578
579 2005-05-30 Akim Demaille <akim@epita.fr>
580
581 * data/lalr1.cc (_): New.
582 Translate the various messages.
583
584 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
585
586 Fix infringement on user name space reported by Bruno Haible.
587 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
588 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
589 the user's name space.
590 (alloca): Include <stdlib.h> to get it, if it's not built in.
591 (YYMALLOC, YYFREE): Define only if needed.
592 (malloc, free): Declare, but only if needed, as this infringes on
593 the user name space.
594
595 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
596
597 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
598 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
599 with %d format.
600 * lib/ebitset.c (min, max): Undef before defining.
601 * lib/vbitset.c (min, max): Likewise.
602 * lib/subpipe.c (create_subpipe): Save local variables in case
603 vfork clobbers them.
604
605 2005-05-24 Bruno Haible <bruno@clisp.org>
606
607 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
608 error message syntax used by gcc-4.0.
609
610 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
611
612 * README: Mention m4 1.4.3. Remove obsolete advice about
613 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
614
615 * bootstrap: Remove workaround for problem I encountered with
616 gettext 0.14.1; it seems to be fixed now.
617
618 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
619
620 * NEWS: Version 2.0a.
621
622 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
623 the previous change.
624
625 Various maintainer cleanups.
626 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
627 conftest*, for benefit of CVS commands run at the same time as
628 "configure". Add build-aux, since "bootstrap" now creates it and
629 its subfiles.
630 * Makefile.cfg (move_if_change): Remove.
631 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
632 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
633 (po_repo, do-po-update, po-update, wget_files, get-targets):
634 (config.guess-url_prefix, config.sub-url_prefix):
635 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
636 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
637 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
638 Remove.
639 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
640 this is now the recommended name.
641 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
642 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
643 ylwrap. These files now go into build-aux.
644 * config/move-if-change: Remove.
645 * config/prev-version.txt: Bump from 1.75 to 2.0.
646
647 * bootstrap: Add stdio-safer, unistd-safer modules.
648 Remove m4/glibc2.m4 (introduced by latest gnulib, but
649 we don't need it).
650 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
651 fopen-safer.c, stdio-safer.h, unistd-safer.h.
652 * lib/subpipe.c: Include "unistd-safer.h".
653 (create_subpipe): Make sure all the newly-created
654 file descriptors are > 2, so that diagnostics don't
655 get sent down them (which might cause Bison to hang, in theory).
656 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
657 * src/files.c (xfopen): Use fopen_safer, not fopen.
658
659 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
660 yesterday's yacc.c fix.
661
662 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
663
664 * data/glr.c, data/lalr1.cc: Update copyright date.
665
666 Fix a destructor bug reported by Wolfgang Spraul in
667 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
668 * data/yacc.c (yyabortlab): Don't call destructor, and
669 don't set yychar to EMPTY.
670 (yyoverflowlab): Don't call destructor.
671 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
672 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
673 since we no longer output the message "discarding lookahead token
674 end of input ()".
675
676 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
677
678 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
679 fix a small glitch in debugging output.
680 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
681 after YY_SYMBOL_PRINT where needed.
682
683 (struct yyGLRState): Add some comments.
684 (struct yySemanticOption): Add some comments.
685 (union yyGLRStackItem): Add comment.
686
687 (yymergeOptionSets): Correct this to properly perform the union,
688 avoiding infinite reported by Michael Rosien.
689 Update comment.
690
691 * tests/glr-regression.at: Add test for GLR merging error reported
692 by M. Rosien.
693

731
732 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
733
734 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
735 Problem reported by Ralf Menzel.
736
737 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
738
739 * tests/actions.at: Test that stack overflow invokes destructors.
740 From Marcus Holland-Moritz.
741 * data/yacc.c (yyerrlab): Move the code that destroys the stack
742 from here....
743 (yyreturn): to here. That way, destructors are called properly
744 even if the stack overflows, or the user calls YYACCEPT or
745 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
746 (yyoverflowlab): Destroy the lookahead.
747
748 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
749
750 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
751
752 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
753
754 * NEWS: Bison-generated C parsers no longer quote literal strings
755 associated with tokens.
756 * src/output.c (prepare_symbols): Don't escape strings,
757 since users don't want to see C escapes.
758 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
759 in diagnostics.
760 * tests/input.at (Torturing the Scanner): Likewise.
761 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
762
763 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
764
765 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
766 the data size is known to be too small and we can't increase it.
767 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
768
769 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
770
771 * src/parse-gram.y: Include quotearg.h.
772 (string_as_id): Quote $1 before using it as a key, since the
773 lexer no longer quotes it for us.
774 (string_content): Don't strip quotes, since lexer no longer
775 quotes it for us.
776 * src/scan-gram.l: Include quotearg.h.
777 ("\""): Omit quote.
778 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
779 a key, since the rest of the lexer doesn't quote it.
780 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
781 * tests/regression.at (Token definitions): Check for backslashes
782 in token strings.
783
784 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
785 (YYSIZE_T): Define to unsigned long int when using an older compiler.
786 (yyparse): Revamp code to generate long syntax error message, to
787 make it easier to translate, and to avoid problems with arithmetic
788 overflow. Change "virtual memory" to "memory" in diagnostic, since
789 we don't know whether the memory is virtual.
790
791 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
792
793 * NEWS: Bison-generated C parsers now use the _ macro to
794 translate strings.
795 * data/yacc.c (_) [!defined _]: New macro.
796 All English strings wrapped inside this macro.
797 * doc/bison.texinfo (Bison Parser): Document _.
798 * po/POTFILES.in: Include src/parse-gram.c, since it now
799 includes translateable strings that parse-gram.y doesn't.
800
801 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
802
803 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
804 reverting the 2004-10-11 change to this function.
805 (symbol_check_alias_consistency): Don't call symbol_type_set
806 if the type name is already correct.
807 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
808
809 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
810
811 * tests/regression.at (Token definitions): Don't use a token named
812 c, as that generates a "#define c ..." that runs afoul of buggy
813 stdlib.h that uses the identifier c as a member of struct
814 drand48_data. Problem reported by Horst Wente.
815
816 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
817
818 * bootstrap: Change translation URL from
819 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
820 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
821 redirection glitches. Problem reported by twlevo@xs4all.nl.
822
823 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
824
825 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
826 after operands; POSIX says this isn't portable for the c99 command.
827
828 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
829
830 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
831 immediately if a data overrun has occurred; this may help us track
832 down what may be a spurious failure on MacOS.
833
834 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
835
836 Respond to problems reported by twlevo@xs4all.nl.
837
838 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
839
840 * src/vcg.h: Comment fix.
841 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
842 (G_CMAX): Change to -1 instead of INT_MAX.
843
844 * data/yacc.c (yyparse): Omit spaces before #line.
845
846 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
847
848 * src/tables.c (state_number_to_vector_number): Put it inside an
849 "#if 0", since it's not currently used. Problem reported by
850 Roland McGrath.
851
852 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
853
854 * src/output.c (escaped_output): Renamed from
855 escaped_file_name_output, since we now use it for symbol tags as
856 well. All uses changed.
857 (symbol_destructors_output, symbol_printers_output):
858 Escape symbol tags too.
859 Problem reported by Matyas Forstner in
860 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
861
862 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
863 not needed.
864 * src/output.c (user_actions_output, token_definitions_output,
865 symbol_destructors_output, symbol_printers_output): Likewise.
866 * src/reader.c (prologue_augment): Likewise.
867 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
868
869 * src/vcg.c (output_edge): Don't quote linestyle arg.
870 Problem reported by twlevo@xs4all.nl.
871
872 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
873
874 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
875 example, reported by Derek M Jones. Also, make the example even
876 more outrageous, to better illustrate how bad the problem is.
877
878 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
879
880 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
881 putsym. Typo reported by Sebastian Piping.
882
883 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
884
885 * doc/bison.texinfo (Language and Grammar): some -> same
886 (Epilogue): int he -> in the
887 Typos reported by Sebastian Piping via Justin Pence.
888
889 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
890
891 * tests/glr-regression.at (Improper handling of embedded actions
892 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
893 embedded actions and $-N in GLR parsers", work around an Autoconf bug
894 with dollar signs in test names.
895 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
896 for a similar reason.
897
898 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
899
900 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
901 wants to redefine G_VIEW.
902
903 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
904
905 * src/vcg.c (get_view_str): Remove case for normal_view.
906 Problem reported by twlevo@xs4all.nl.
907
908 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
909
910 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
911 Problem reported by twlevo@xs4all.nl.
912
913 * doc/bison.texinfo: Change @dircategory from "GNU programming
914 tools" to "Software development". Requested by Richard Stallman
915 via Karl Berry.
916
917 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
918
919 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
920 Problem reported by twlevo@xs4all.nl.
921
922 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
923
924 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
925 keyword; it's not needed with modern compilers, and it doesn't
926 affect correctness with older compilers. Suggested by
927 twlevo@xs4all.nl.
928
929 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
930
931 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
932 gcc -Wswitch-default.
933 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
934 * data/yacc.c (yyparse): Likewise.
935
936 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
937
938 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
939 already. Let config.h define any nonstandard values.
940
941 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
942
943 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
944 for the benefit of slower hosts. Problem reported by
945 Nelson H. F. Beebe.
946
947 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
948
949 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
950 being defined and not used.
951 * data/lalr1.cc (yyparse): Likewise.
952 Use "if (false)" rather than "if (0)".
953
954 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
955
956 * TODO: Mention that we should allow NUL bytes in tokens.
957
958 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
959
960 * src/scan-skel.l (<<EOF>>): Don't close standard output.
961 Problem reported by Hans Aberg.
962
963 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
964
965 * src/getargs.c (version): Happy new year; update overall
966 program copyright date from 2004 to 2005.
967
968 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
969 Problem reported by Hans Aberg.
970 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
971 (Output file names.): Add a test for the case when standard output
972 is closed.
973
974 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
975
976 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
977 to fix an oversight in the Bison 2.0 manual.
978
979 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
980
981 * NEWS: Version 2.0. Reformat the existing news items since
982 1.875, so that related items are grouped together.
983 * configure.ac (AC_INIT): Bump version to 2.0.
984 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
985
986 * tests/torture.at (Exploding the Stack Size with Alloca): Set
987 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
988 otherwise, we're not testing alloca. Unfortunately there's no
989 simple way to consult HAVE_ALLOCA here.
990
991 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
992 for yymsg, too.
993
994 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
995 hand. This avoids a warning about comparing int to size_t when
996 GCC warnings are enabled.
997
998 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
999
1000 * NEWS: Bison-generated parsers no longer default to using the
1001 alloca function (when available) to extend the parser stack, due
1002 to widespread problems in unchecked stack-overflow detection.
1003 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
1004 responsibility to set it to a positive value. This lets the user
1005 specify a value that is not a preprocessor constant.
1006 * data/yacc.c (YYMAXDEPTH): Likewise.
1007 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
1008 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
1009 to be a compile-time constant. However, explain the constraints on it.
1010 Also, explain the constraints on YYINITDEPTH.
1011 (Table of Symbols): Explain that alloca is no longer the default.
1012 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
1013 to 1.
1014
1015 * doc/bison.texinfo (Location Default Action): Mention that n must
1016 be zero when k is zero. Suggested by Frank Heckenbach.
1017
1018 2004-12-22 Akim Demaille <akim@epita.fr>
1019
1020 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
1021 (parser::state_type, parser::semantic_type, parser::location_type):
1022 Private, not public.
1023 (parser::parse): Return ints, not bool.
1024 Returning a bool introduces a problem: 0 corresponds to false, and
1025 it seems weird to return false on success. Returning true changes
1026 the conventions for yyparse.
1027 Alternatively we could return void and send an exception.
1028 There is no clear consensus (yet?).
1029 (state_stack, semantic_stack, location_stack): Rename as...
1030 (state_stack_type, semantic_stack_type, location_stack_type): these.
1031 Private, not public.
1032 * tests/c++.at: New.
1033 * tests/testsuite.at, tests/Makefile.am: Adjust.
1034
1035 2004-12-21 Akim Demaille <akim@epita.fr>
1036
1037 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
1038
1039 2004-12-21 Akim Demaille <akim@epita.fr>
1040
1041 Don't impose std::string for filenames.
1042
1043 * data/lalr1.cc (b4_filename_type): New.
1044 (position::filename): Use it.
1045 (parser.hh): Move the inclusion of stack.hh and location.hh below
1046 the user code, so that needed headers for the filename type can be
1047 included first.
1048 Forward declare them before the user code.
1049 * tests/Makefile.am (check-local, installcheck-local): Pass
1050 TESTSUITEFLAGS to the TESTSUITE.
1051
1052 2004-12-20 Akim Demaille <akim@epita.fr>
1053
1054 Use more STL like names: my_class instead of MyClass.
1055
1056 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
1057 (SemanticStack, SemanticType, StateStack, StateType)
1058 (TokenNumberType, Stack, Slice, Traits, Parser::location)
1059 (Parser::value): Rename as...
1060 (location_stack, location_type, rhs_number_type, semantic_stack)
1061 (semantic_type, state_stack, state_type, token_number_type, stack)
1062 (slice, traits, parser::yylloc, parser::yylval): these.
1063
1064 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
1065
1066 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
1067
1068 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
1069 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
1070
1071 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
1072
1073 Remove uses of 'short int' and 'unsigned short int'. This raises
1074 some arbitrary limits. It uses more memory but nowadays that's
1075 not much of an issue.
1076
1077 This change does not affect the generated parsers; that's a different
1078 task, as some users will want to conserve memory there.
1079
1080 Ideally we should use size_t to represent all object counts, and
1081 something like ptrdiff_t to represent signed differences of object
1082 counts; but that will require more code-cleanup than I have the
1083 time to do right now.
1084
1085 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
1086 Use size_t, not int or short int, to count objects.
1087 * src/closure.c (nritemset, closure): Likewise.
1088 * src/closure.h (nritemset, closure): Likewise.
1089 * src/nullable.c (nullable_compute): Likewise.
1090 * src/print.c (print_core): Likewise.
1091 * src/print_graph.c (print_core): Likewise.
1092 * src/state.c (state_compare, state_hash): Likewise.
1093 * src/state.h (struct state): Likewise.
1094 * src/tables.c (default_goto, goto_actions): Likewise.
1095
1096 * src/gram.h (rule_number, rule): Use int, not short int.
1097 * src/output.c (prepare_rules): Likewise.
1098 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
1099 errs, reductions): Likewise.
1100 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
1101 Likewise.
1102 * src/tables.c (vector_number, tally, action_number,
1103 ACTION_NUMBER_MINIMUM): Likewise.
1104 * src/output.c (muscle_insert_short_int_table): Remove.
1105
1106 2004-12-17 Akim Demaille <akim@epita.fr>
1107
1108 * data/lalr1.cc: Extensive Doxygenation.
1109 (error_): Rename as...
1110 (error): this, since it is visible to the user.
1111 Adjust callers.
1112 (Parser::message): Now an automatic variable from...
1113 (Parser::yyreport_syntax_error_): here.
1114 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
1115 Parser::error.
1116 * tests/input.at: Escape $.
1117
1118 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
1119
1120 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
1121 Parenthesize rhs to avoid obscure problems with mistakes like
1122 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
1123 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
1124 b4_rhs_location): Likewise.
1125 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
1126 b4_rhs_location): Likewise.
1127
1128 2004-12-16 Akim Demaille <akim@epita.fr>
1129
1130 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
1131 yacc.c: be sure to stay within yycheck_.
1132 * tests/actions.at: Re-enable C++ tests.
1133
1134 2004-12-16 Akim Demaille <akim@epita.fr>
1135
1136 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
1137 real.
1138
1139 2004-12-16 Akim Demaille <akim@epita.fr>
1140
1141 Use #define to handle the %name-prefix.
1142
1143 * data/glr.c, data/yacc.c: Comment changes.
1144 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
1145 so that one can refer to yylex in the parser file, and have it
1146 renamed, as is the case with other skeletons.
1147
1148 2004-12-16 Akim Demaille <akim@epita.fr>
1149
1150 Move lalr1.cc internals into yy*.
1151
1152 * data/lalr1.cc (semantic_stack_, location_stack_, state_stack_)
1153 (semantic_stack_, location_stack_, pact_, pact_ninf_, defact_)
1154 (pgoto_, defgoto_, table_, table_ninf_, check_, stos_, r1_, r2_)
1155 (name_, rhs_, prhs_, rline_, token_number_, eof_, last_, nnts_)
1156 (empty_, final_, terror_, errcode_, ntokens_)
1157 (user_token_number_max_, undef_token_, n_, len_, state_, nerrs_)
1158 (looka_, ilooka_, error_range_, nerrs_):
1159 Rename as...

1168 these.
1169
1170 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
1171
1172 Fix some problems reported by twlevo at xs4all.
1173 * src/symtab.c (symbol_new): Report an error if the input grammar
1174 contains too many symbols. This is better than calling abort() later.
1175 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
1176 (struct node, struct graph):
1177 Rename member expand to stretch. All uses changed.
1178 (struct graph): Remove member layoutalgorithm. All uses removed.
1179 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
1180 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
1181 All uses changed.
1182 (N_STRETCH): Rename from N_EXPAND. All uses changed.
1183
1184 2004-12-15 Akim Demaille <akim@epita.fr>
1185

1187 Add more Doxygen comments.
1188 (symprint_, stack_print_, reduce_print_, destruct_, pop)
1189 (report_syntax_error_, translate_): Rename as...
1190 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
1191 (yypop_, yyreport_syntax_error_, yytranslate_): this.
1192
1193 2004-12-15 Akim Demaille <akim@epita.fr>
1194
1195 * data/lalr1.cc (lex_): Rename as...
1196 (yylex_): this.
1197 Move the trace here.
1198 Take the %name-prefix into account.
1199 Reported by Alexandre Duret-Lutz.
1200
1201 2004-12-15 Akim Demaille <akim@epita.fr>
1202
1203 Simplify the C++ parser constructor.
1204
1205 * data/lalr1.cc (debug_): Rename as...
1206 (yydebug_): so that the parser's internals are always in the yy*
1207 pseudo namespace.
1208 Adjust uses.
1209 (b4_parse_param_decl): Remove the leading comma as it is now only
1210 called as unique argument list.
1211 (Parser::Parser): Remove the constructor accepting a location and
1212 an initial debugging level.
1213 Remove from the other ctor the argument for the debugging level.
1214 (debug_level_type, debug_level, set_debug_level): New.
1215
1216 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
1217 constructor calls.
1218
1219 2004-12-15 Akim Demaille <akim@epita.fr>
1220
1221 Remove b4_root related material: failure experiment
1222 (which goal was to allow to derive from a class).
1223
1224 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
1225 definitions and uses.
1226
1227 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
1228
1229 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
1230 not 2, since it's not portable to subtract 1 from the start of an
1231 array. The new item 0 is never set or used. All uses changed.
1232
1233 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
1234 the default definition of YYLLOC_DEFAULT. Problem reported
1235 by Frank Heckenbach.
1236
1237 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
1238
1239 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
1240 the normal case and one for the error case. Just use the
1241 first one uniformly. Problem reported by Frank Heckenbach.
1242 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
1243 use exactly the same macro in both places.
1244 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
1245 so that the normal-case YYRHSLOC works for the error case too.
1246 All uses changed.
1247 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
1248 (YYLLOC_DEFAULT): Use the same macro as glr.c.
1249 * doc/bison.texinfo (Location Default Action): Don't claim that
1250 we have an array of locations. Use the same macro for both glr
1251 and lalr parsers. Mention YYRHSLOC. Mention what happens when
1252 the index is 0.
1253
1254 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
1255
1256 * HACKING: Update email addresses to send announcements to.
1257
1258 * configure.ac (AC_INIT): Bump version to 1.875f.
1259
1260 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
1261

1263 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
1264
1265 * src/scan-skel.l: Include "complain.h", for "fatal".
1266
1267 * src/relation.h (relation_print, relation_digraph):
1268 Relation sizes are of type relation_node, not size_t (this is
1269 merely a doc fix, since the two types are equivalent).
1270 (relation_transpose): Relation sizes are of type relation_node,
1271 not int.
1272 * src/relation.c: Likewise.
1273 (top, infinity): Now of type relation_node, not int.
1274 (traverse, relation_transpose): Use relation_node, not int.
1275
1276 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
1277 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
1278 (yyparse): Remove unused local introduced in 2004-10-25 patch.
1279
1280 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
1281 specifying whether the test should be skipped. Use it tp
1282 specify that the [%defines %skeleton "lalr1.cc"] tests currently
1283 fail on some hosts, and should be skipped.
1284

1287 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
1288 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
1289 unless otherwise specified below.
1290
1291 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
1292 to allocate kernel_base, kernel_items, kernel_size, since
1293 they needn't be initialized to 0.
1294 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
1295 * src/closure.c (new_closure): Likewise, for itemset.
1296 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
1297 * src/lalr.c (set_goto_map): Likewise, for temp_map.
1298 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
1299 (build_relations): Likewise for edge, states1, includes.
1300 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
1301 * src/reader.c (packgram): Likewise, for ritem, rules.
1302 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
1303 * src/relation.c (relation_digraph): Likewise for VERTICES.
1304 (relation_transpose): Likewise for new_R, end_R.
1305 * src/symtab.c (symbols_token_translations_init): Likewise for
1306 token_translations.
1307 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
1308 (token_actions): Likewise for yydefact, actrow, conflrow,
1309 conflict_list.
1310 (save_column): Likewise for froms[symno], tos[symno].
1311 (goto_actions): Likewise for state_count.
1312 (pack_table): Likewise for base, pos, check.
1313 (tables_generate): Likewise for width.
1314
1315 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
1316 for initial core. Just have a separate core, so we needn't worry
1317 about whether kernel_size and kernel_base are initialized.
1318
1319 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
1320 kernel_size, kernel_items): Remove unnecessary initialization.
1321 * src/conflicts.c (conflicts): Likewise.
1322 * src/derives.c (derives): Likewise.
1323 * src/muscle_tablc (muscle_insert): Likewise.
1324 * src/relation.c (relation_digraph): Likewise.
1325 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
1326 conflrow, conflict_table, conflict_list, table, check):
1327 Likewise.
1328
1329 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
1330 This is because all callers pass unsigned int.
1331 * src/closure.h (new_closure): Likewise.
1332
1333 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
1334 (build_relations): Initialize includes[i] in all cases.
1335 * src/reader.c (packgram): Always initialize rules[ruleno].prec
1336 and rules[ruleno].precsym. Initialize members in order.
1337 * src/relation.c (relation_transpose): Always initialize new_R[i]
1338 and end_R[i].
1339 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
1340
1341 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
1342 conflict_list[0] was always 0, but now it isn't initialized.
1343
1344 * src/table.c (table_grow): When conflict_table grew, the grown
1345 area wasn't cleared. Fix this.
1346
1347 * lib/.cvsignore: Add strdup.c, strdup.h.
1348 * m4/.cvsignore: Add strdup.m4.
1349
1350 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
1351
1352 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
1353 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
1354 GOTO_NUMBER_MAXIMUM, since we occasionally compute
1355 ngotos + 1 without checking for overflow.
1356 (build_relations): Use END_NODE, not -1, to denote end of edges.
1357 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
1358 build_relations): Use goto_number, not int, for goto numbers.
1359 * src/tables.c (save_column, default_goto): Likewise.
1360
1361 2004-11-23 Akim Demaille <akim@epita.fr>
1362
1363 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
1364 of #defining from yystype.
1365 Don't typedef yystype, C++ does not need it.
1366 This lets it possible to forward declare it as union.
1367
1368 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
1369
1370 * bootstrap (gnulib_modules): Add extensions.
1371 Problem reported by Jim Meyering.
1372
1373 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
1374
1375 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
1376 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
1377 src/system.h, src/tables.c: XFREE -> free, to accommodate
1378 recent change to gnulib xalloc.h.
1379 Problem reported by Jim Meyering.
1380
1381 2004-11-17 Akim Demaille <akim@epita.fr>
1382
1383 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
1384
1385 2004-10-28 Akim Demaille <akim@epita.fr>,
1386 Alexandre Duret-Lutz <adl@gnu.org>
1387
1388 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
1389 changes.
1390 (YYCDEBUG): Adjust.
1391 Use it instead of cdebug_.
1392 (Parser::debug_stream, Parser::set_debug_stream): New.
1393 (Parser::symprint_): Define cdebug_ for temporary backward
1394 compatibility.
1395 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
1396 debug_stream ().
1397
1398 2004-11-17 Akim Demaille <akim@epita.fr>
1399
1400 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
1401 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
1402 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
1403 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
1404
1405 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
1406
1407 * data/glr.c (yyloc_default): Remove; not used.
1408 Problem reported by Frank Heckenbach.
1409
1410 2004-10-25 Akim Demaille <akim@epita.fr>
1411
1412 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
1413 Introduce another definition to address simple location arrays.
1414 (yyGLRStack): New member: yyerror_range.
1415 (yyrecoverSyntaxError, yyparse): Update it.
1416 (yyrecoverSyntaxError): Use it when shifting the error token to
1417 have an accurate range, equivalent to the one computed by both
1418 yacc.c and lalr1.cc.
1419 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
1420 that column numbers start at column 0, as per GNU Coding
1421 Standards, the others tests, and the doc.
1422 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
1423 Adjust to the above change (first column is 0).
1424 And adjust the location of the "<error>", now covering the whole
1425 line.
1426
1427 2004-10-22 Akim Demaille <akim@epita.fr>
1428 and Paul Eggert <eggert@cs.ucla.edu>
1429
1430 Remove some arbitrary limits on goto numbers and relations.
1431 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
1432 initial values, since they're never used.
1433 (set_goto_map): ngotos is now unsigned, so test for overflow
1434 by seeing whether it wraps around to zero.
1435 * src/lalr.h (goto_number): Now size_t, not short int.
1436 (GOTO_NUMBER_MAXIMUM): Remove.
1437 * src/relation.c (relation_print, traverse, relation_transpose):
1438 Check for END_NODE rather than looking at sign.
1439 * src/relation.h (END_NODE): New macro.
1440 (relation_node): Now size_t, not short int.
1441
1442 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
1443
1444 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
1445 keyword, not an identifier. Problem reported by Baron Schwartz in
1446 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
1447
1448 2004-10-11 Akim Demaille <akim@epita.fr>
1449
1450 * src/symtab.c (symbol_check_alias_consistency): Also check
1451 type names, destructors, and printers.
1452 Reported by Alexandre Duret-Lutz.
1453 Recode the handling of associativity and precedence in terms
1454 of symbol_precedence_set.
1455 Accept no redeclaration at all, not even equal to the previous
1456 value.
1457 (redeclaration): New.
1458 Use it to factor redeclaration complaints.
1459 (symbol_make_alias): Don't set the type of the alias, let
1460 symbol_check_alias_consistency do it as for other features.
1461 * src/symtab.h (symbol): Add new member prec_location, and
1462 type_location.
1463 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
1464 * tests/input.at (Incompatible Aliases): New.
1465
1466 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
1467
1468 .cvsignore fixes to accommodate gnulib changes,
1469 and the practice of naming build directories "_build".
1470 * .cvsignore: Add "_*". Sort.
1471 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
1472 * m4/.cvsignore: Add "*_gl.m4".
1473
1474 2004-10-06 Akim Demaille <akim@epita.fr>
1475
1476 * src/parse-gram.y (add_param): Fix the truncation of trailing
1477 spaces.
1478
1479 2004-10-05 Akim Demaille <akim@epita.fr>
1480
1481 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
1482 whether the reducion was empty or not. This leaves room to
1483 improve the use of YYLLOC_DEFAULT in such a case.
1484 lalr1.cc is still experimental, so changing this is acceptable.
1485 And finally, there are probably not many users who changed the
1486 handling of locations in GLR, so changing is admissible too.
1487
1488 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
1489 empty reduction, set @$ to an empty location ending the previously
1490 stacked symbol.
1491 Adjust uses to make sure the code is triggered on empty
1492 reductions.
1493 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
1494 expected output: empty reductions have empty locations.
1495
1496 2004-09-29 Akim Demaille <akim@epita.fr>
1497
1498 * data/lalr1.cc: Move towards a more standard C++ coding style
1499 for templates: Class < T > -> Class<T>.
1500
1501 2004-09-29 Akim Demaille <akim@epita.fr>
1502
1503 * data/lalr1.cc: Reinstall the former ctor, for sake of
1504 compatibility, but warn it will be removed.
1505 Move towards a more standard C++ coding style (i.e., type *var ->
1506 type* var).
1507
1508 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
1509
1510 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
1511 since it's less likely to work if NULs are involved in the future.
1512
1513 2004-09-27 Akim Demaille <akim@epita.fr>
1514
1515 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
1516
1517 2004-09-27 Akim Demaille <akim@epita.fr>
1518
1519 * data/lalr1.cc (b4_parse_param_decl_1): New.
1520 (b4_parse_param_decl): Use it to have different names between attribute
1521 and argument names.
1522 (b4_cc_constructor_call): Likewise.
1523
1524 2004-09-24 Akim Demaille <akim@epita.fr>
1525
1526 * src/parse-gram.y (add_param): Strip the leading and trailing
1527 blanks from a formal argument declaration.
1528 (YY_LOCATION_PRINT): New.
1529
1530 2004-09-24 Akim Demaille <akim@epita.fr>
1531
1532 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
1533 after the location.
1534
1535 2004-09-24 Akim Demaille <akim@epita.fr>
1536
1537 * doc/bison.texinfo (Table of Symbols): Sort.
1538
1539 2004-09-21 Akim Demaille <akim@epita.fr>
1540
1541 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
1542 the useless parentheses.
1543 Suggested by Paul Eggert.
1544
1545 2004-09-20 Akim Demaille <akim@epita.fr>
1546
1547 Let the initial-action act on the look-ahead, and use it for the
1548 "initial push" (corresponding to an hypothetical beginning-of-file).
1549 And let lalr1.cc honor %initial-action.
1550
1551 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
1552 example.
1553 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
1554 (Parser::Parser): Remove the ctor that used to initialize it.
1555 (Parser::parse): Like in the other skeletons, issue the "starting
1556 parse" message before any action.
1557 Honor %initial-action.
1558 Initialize the stacks with the lookahead.
1559 * data/yacc.c: Let $$ and @$ in %initial-action designate the
1560 look-ahead.
1561 Push them in the stacks.
1562 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
1563
1564 2004-09-20 Akim Demaille <akim@epita.fr>
1565
1566 * doc/bison.texinfo (Initial Action Decl): New.
1567
1568 2004-09-20 Akim Demaille <akim@epita.fr>
1569
1570 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
1571 clearer criterion to define it.
1572 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
1573 When reducing on an empty RHS, use the latest stacked location as
1574 location.
1575 yylloc is not always available.
1576 * data/glr.c: Likewise.
1577 Also, honor initial-actions.
1578
1579 2004-09-20 Akim Demaille <akim@epita.fr>
1580
1581 * data/yacc.c (YY_LOCATION_PRINT): New.
1582 Define when we know YYLTYPE's structure, i.e., when the default
1583 YYLLOC_DEFAULT is used.
1584 * data/c.m4 (b4_yysymprint_generate): Use it.
1585 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
1586 value of the result.
1587 (error_start_): Replace with...
1588 (error_range_): this location array.
1589 This allows to replace code relying on the implementation of
1590 locations by portable code.
1591 * data/yacc.c (yylerrsp): Replace with...
1592 (yyerror_range): this.
1593 Every time a token is popped, update yyerror_range[0], to have an
1594 accurate location for the error token.
1595 * data/glr.c (YY_LOCATION_PRINT): New.
1596 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
1597 deference a pointer.
1598 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
1599 report the location in %printers.
1600
1601 * src/scan-skel.l: Instead of abort, report error messages to ease
1602 understanding skeleton scanning failures.
1603
1604 2004-09-16 Akim Demaille <akim@epita.fr>
1605
1606 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
1607 (iterator, const_iterator): these, to be more in the C++ spirit.
1608 Also, return reverse iterators so that when displaying the stack
1609 we display its bottom first.
1610 (Parser::stack_print_, Parser::reduce_print_): Match the messages
1611 from yacc.c.
1612 We should probably use vector here though.
1613
1614 2004-09-16 Akim Demaille <akim@epita.fr>
1615
1616 Have more complete shift traces.
1617
1618 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
1619 to report Shifts instead of ad hoc YYDPRINTF invocations,
1620 including for the error token.
1621 * data/lalr1.cc (symprint_): Output the location.
1622 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
1623 output the location within the %printer.
1624 Activate GLR tests, at least to make sure they compile properly.
1625 They still don't pass though.
1626 * tests/calc.at: Adjust expect verbose output, since now "Entering
1627 state..." is on a different line than the "Shifting" message.
1628
1629 2004-09-08 Akim Demaille <akim@epita.fr>
1630
1631 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
1632 Bison directive from the Bison file to the invocation of this
1633 macro, so that these directives are passed to
1634 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
1635 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
1636 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
1637 the extra Bison directives instead of the whole series.
1638 Change the grammar so that there are recoverable errors, and
1639 unrecoverable errors. Now we can have the parser give up before
1640 consuming the whole input. As a result we now can observe that
1641 the lookahead is freed when needed.
1642 Change the parser source to parse argv[1] instead of a hard coded
1643 string.
1644 Simplify yylex, and give a value and location to EOF.
1645 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
1646 passed directives already coded in the file.
1647 Add some tests to check the location of "error".
1648 For some tests, the C++ parser is correct, and not yacc.c.
1649 For other tests, they provide different, but unsatisfying, values,
1650 so keep the C++ value so that at least one parser is "correct"
1651 according to the test suite.
1652 (Actions after errors): Remove, this is subsumed by the
1653 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
1654
1655 2004-09-06 Akim Demaille <akim@epita.fr>
1656
1657 * data/lalr1.cc: Adjust the indentation of the labels.
1658 (Parser::pop): New.
1659 Use it.
1660
1661 2004-09-06 Akim Demaille <akim@epita.fr>
1662
1663 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
1664 argument, an informative message.
1665 Call YY_SYMBOL_PRINT.
1666 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
1667 * data/lalr1.cc (destruct_): Likewise.
1668 In addition, no longer depend on b4_yysymprint_generate and
1669 b4_yydestruct_generate to generate these functions, do it "by
1670 hand".
1671
1672 2004-09-03 Akim Demaille <akim@epita.fr>
1673
1674 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
1675 invoked, yydestruct the lookahead.
1676 * tests/calc.at (Calculator $1): Update the expected lengths of
1677 traces: there is an added line for the discarded lookahead.
1678 * doc/bison.texinfo (Destructor Decl): Some rewording.
1679 Define "discarded" symbols.
1680
1681 2004-09-02 Akim Demaille <akim@epita.fr>
1682
1683 * data/lalr1.cc (translate_, destruct_): No reason to be static.
1684
1685 2004-09-02 Akim Demaille <akim@epita.fr>
1686
1687 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
1688 (YYDSYMPRINTF): Rename as...
1689 (YY_SYMBOL_PRINT): this.
1690 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
1691 two.
1692 Use it instead of direct symprint_ calls.
1693 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
1694 one.
1695
1696 2004-09-02 Akim Demaille <akim@epita.fr>
1697
1698 * data/lalr1.cc (b4_yysymprint_generate): New.
1699 (symprint_): New member function, defined when YYDEBUG.
1700 Use it consistently instead of token/nterm debugging output by
1701 hand.
1702 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
1703 %printer calls to use cdebug_ when using lalr1.cc.
1704
1705 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
1706
1707 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
1708 with #ifdef YYDEBUG.
1709
1710 2004-08-26 Akim Demaille <akim@epita.fr>
1711
1712 * doc/bison.texinfo (Implementing Loops): Rename as...
1713 (Implementing Gotos/Loops): this.
1714
1715 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
1716
1717 Adjust to latest gnulib.
1718 * bootstrap (gnulib_modules): Add xalloc-die.
1719 Set LC_ALL=C so that file names sort consistently.
1720 Prefer the gnulib copies of gettext.m4, glibc21.m4,
1721 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
1722 uintmax_t.m4, ulonglong.m4.
1723 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
1724 po.m4 since we are now using _gl.m4 instead.
1725
1726 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
1727
1728 * src/scan-action.l: Remove. Scanning of semantic actions is
1729 handled in scan-gram.l.
1730
1731 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
1732
1733 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
1734
1735 * src/location.h (struct): The file member is a uniqstr.
1736 (equal_boundaries): Use UNIQSTR_EQ for comparison.
1737
1738 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
1739
1740 Fix bug with non-%union parsers that have printers or destructors,
1741 which led to a Bison core dump. Reported by Peter Fales in
1742 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
1743
1744 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
1745 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
1746 not to our own type.
1747 * src/output.c (symbol_destructors_output, symbol_printers_output):
1748 Don't assume %union.
1749 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
1750 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
1751 UNION-FLAG. All callers changed.
1752 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
1753 Use type char, not unsigned int, when declaring an array of char;
1754 this lets us remove a cast.
1755 (Printers and Destructors): Add non-%union test cases.
1756
1757 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
1758
1759 * doc/bison.texinfo: Minor editorial changes, mostly to the new
1760 GLR writeups. E.g., avoid frenchspacing and the future tense,
1761 change "lookahead" to "look-ahead", and change "wrt" to "with
1762 respect to".
1763
1764 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
1765
1766 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
1767 New sections, split off from the GLR Parsers section. Put the new
1768 Simple GLR Parser near the start of the GLR section, for clarity.
1769 Rewrite connective text.
1770
1771 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

1776
1777 * NEWS, TODO, doc/bison.texinfo:
1778 Use "look-ahead" instead of "lookahead", to be consistent.
1779 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
1780 while we're fixing "look-ahead".

1807 (trivial change).
1808 * configure.ac (O0CXXFLAGS): New var.
1809 * tests/atlocal.in (CXXFLAGS): Use it.
1810
1811 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>

1815 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
1816
1817 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
1818 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
1819 Output to a .cc file for C++, not to a .c file.
1820 * tests/calc.at (AT_CHECK_CALC): Likewise.
1821 * tests/regression.at (AT_CHECK_DANCER): Likewise.
1822 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
1823
1824 2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
1825
1826 * tests/calc.at, tests/actions.at: Workaround for SGI

1828
1829 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
1830
1831 Spent a few hours checking out which prerequisite versions the
1832 current sources actually require. I went all the way back to
1833 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
1834 a seemingly endless set of combinations of versions more recent
1835 than that. The bottom line is that the current sources require
1836 fairly recent versions of the build tools, and it'll be some work
1837 to change this.
1838 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
1839 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
1840 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
1841 Add comments explaining why those particular versions are
1842 currently needed.
1843
1844 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
1845 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
1846 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
1847
1848 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
1849 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
1850
1851 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
1852
1853 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
1854 0.11.5. Suggested by Bruno Haible.
1855 * bootstrap: Remove gettext version checking.
1856
1857 * doc/bison.texinfo (Decl Summary): Also mention that %union
1858 can depend on prerequisite types. Problem reported by Tim
1859 Van Holder.
1860
1861 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
1862
1863 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
1864 * README-alpha: Don't tell people not to package this.
1865
1866 * bootstrap: Don't assume $(...) works; use `...` instead.
1867 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
1868 gettext better.
1869
1870 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
1871 put into the -d output file, and mention what to do if YYSTYPE is
1872 defined as a macro.
1873
1874 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
1875
1876 Undo change made earlier today: it caused autopoint to not bring
1877 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
1878 autopoint's.
1879
1880 * bootstrap: Check that gettext version matches what's in
1881 configure.ac. Warn users to ignore robots.txt ERROR 404.
1882 * bootstrap: Undo today's earlier change (logged below).
1883 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
1884
1885 The gettext version checking is causing more trouble than it's
1886 curing; remove it. Problem reported by Paul Hilfinger.
1887
1888 * bootstrap: Issue a warning that one can expect a message
1889 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
1890 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
1891
1892 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
1893
1894 Ensure that the C++ compiler used for testing actually works on a
1895 simple test program; if not, skip the C++-related tests. Problem
1896 reported by Vin Shelton in:
1897 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
1898
1899 * m4/cxx.m4: New file.
1900 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
1901 * tests/atlocal.in (BISON_CXX_WORKS): Add.
1902 * tests/local.at (AT_COMPILE_CXX): Use it.
1903
1904 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
1905
1906 * data/glr.c (yylloc): Output this macro even if locations are not
1907 being generated, as the GLR parser needs it even in that case.
1908 Problem reported by Troy A. Johnson
1909 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
1910
1911 * configure.ac (AC_INIT): Update to 1.875e.
1912
1913 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
1914
1915 * NEWS: Version 1.875d.
1916 * configure.ac (AC_INIT): Likewise.
1917 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
1918
1919 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
1920 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
1921 lalr1.cc runs afoul of the first, and the last two are no longer
1922 supported by GCC 3.4.0.
1923 * README: Mention GNU m4 1.4 or later; mention m4 patches.
1924 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
1925
1926 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
1927
1928 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not

1933
1934 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
1935
1936 * NEWS: Unescaped newlines are no longer allowed in char & strings.
1937
1938 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
1939 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
1940 character and string literals.
1941 (unexpected_end): New function.
1942 (unexpected_eof): Use it.
1943 (unexpected_newline): New function.
1944 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
1945 actions.
1946
1947 * NEWS: Document %expect-rr.
1948
1949 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
1950 Fix typo by replacing $1 with $option.
1951 Remove more 'intl'-related files.
1952 Don't DEFUN AM_INTL_SUBDIR twice.
1953
1954 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
1955 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
1956 strtoul.c.
1957 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
1958 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
1959 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
1960 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
1961 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
1962 * src/.cvsignore: Add *.output.
1963
1964 * src/parse-gram.y: Put copyright notice inside %{ %} so it
1965 gets copied to the output file.
1966
1967 2004-04-28 Paul Eggert <eggert@twinsun.com>
1968
1969 Get files from the gnulib and po repositories, instead of relying
1970 on them being in our CVS. Upgrade to latest versions of gnulib
1971 and Automake.
1972
1973 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
1974 * bootstrap: Bootstrap from gnulib and po repositories.
1975 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
1976 * README-cvs: Document these changes. Remove version numbers from
1977 mentions of build tools, since they change so often. Mention Flex.
1978
1979 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
1980 (gl_USE_SYSTEM_EXTENSIONS): Add.
1981 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
1982 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
1983 does this for us.
1984 (AC_ISC_POSIX): Remove; we no longer support this
1985 ancient OS, as it gets in the way of latest Autoconf & gnulib.
1986 (AC_HEADER_STDC): Remove: we now assume C89 or better.
1987 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
1988 Do not check for C89 headers, except for locale.h which is used
1989 by the Yacc library and must port to K&R hosts.
1990 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
1991 Do not check for C89 functions, except for setlocale which is
1992 used by the Yacc library.
1993 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
1994 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
1995 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

1997 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
1998 AM_GNU_GETTEXT): Remove; now done by:
1999 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
2000 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
2001 for us.
2002
2003 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
2004 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
2005 Define to empty, as gnulib.mk will do the rest for us.
2006 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
2007 for us.
2008 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
2009 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
2010
2011 * src/files.c: Include gnulib's xstrndup.h.
2012
2013 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
2014 (REALLOC): Use xnrealloc, for likewise.
2015 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
2016 (strnlen, memrchr): Remove decls; functions no longer used.
2017 Include <stpcpy.h>.
2018

2040 Remove, as these files are now generated automatically
2041 by bootstrap or automake.
2042
2043 * po/ChangeLog: Remove: all but one entry was a duplicate
2044 of this file, and I moved that 2000-11-02 entry here.

2068
2069 2004-04-27 Paul Eggert <eggert@twinsun.com>
2070
2071 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
2072 case, as stos_ is now used by destructors due to the 2004-02-09
2073 change.
2074
2075 Remove more K&R C support.
2076 * lib/libiberty.y (PARAMS): Remove. All uses removed.
2077 * lib/subpipe.c (errno): Remove decl.
2078 Include <stdlib.h> unconditionally.
2079 (EXIT_FAILURE): Remove macro.
2080 * src/complain.c (vfprintf, strerror): Remove.

2094 with latest obstack.h.
2095 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
2096 to procedure types, as obstack.h now does that for us.
2097 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
2098
2099 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
2100 so that this include file can stand alone.
2101 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
2102 does this now. Include subpipe.h first after config.h, to
2103 test whether it can stand alone.
2104
2105 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
2106 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
2107 unused declaration.
2108
2109 * tests/synclines.at (%union synch line): Put a dummy member in
2110 the union, because empty unions aren't allowed in C. Caught
2111 by GCC 3.4.0.
2112
2113 2004-04-13 Jim Meyering <jim@meyering.net>
2114
2115 * src/conflicts.c (conflicts_print): Correct format string typo:
2116 use `%%' to produce literal `%'. (trivial change)
2117
2118 2004-03-30 Paul Eggert <eggert@twinsun.com>
2119
2120 * src/getargs.c (version): Update copyright year to 2004.

2159 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
2160
2161 * src/parse-gram.y: Define PERCENT_EXPECT_RR.

2175 for GLR parsers.
2176 Use expected_sr_conflicts in place of expected_conflicts.
2177 Warn if expected_rr_conflicts used in non-GLR parser.
2178
2179 * doc/bison.texinfo: Add documentation for %expect-rr.
2180
2181 2004-03-08 Paul Eggert <eggert@gnu.org>
2182
2183 Add support for hex token numbers. Suggested by Odd Arild Olsen in
2184 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
2185
2186 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
2187 in lalr1.cc.
2188 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
2189 * src/scan-gram.l (scan_integer): New function.
2190 ({int}): Use it.
2191 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
2192 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
2193 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
2194 Say "long int", not "long", for uniformity with GNU style.
2195
2196 2004-02-25 Paul Eggert <eggert@twinsun.com>
2197
2198 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
2199 compilers. This fixes a problem with Intel's C++ compiler being
2200 chatty, reported by Guido Trentalancia in
2201 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
2202
2203 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
2204
2205 Support %destructor and merge error locations in lalr1.cc.
2206
2207 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
2208 (Parser::stos_): Define unconditionally.
2209 (Parser::destruct_): New method. Generate its body with
2210 b4_yydestruct_generate.

2212 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
2213 token which are discarded.
2214 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
2215 error_start_ when erroneous token are discarded.
2216 (Parser::parse) <yyerrlab1>: Compute the location of the error
2217 token so that it covers all the discarded tokens.
2218 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
2219 it can be called with `%skeleton "lalr1.cc"', and do that.
2220
2221 2004-02-02 Paul Eggert <eggert@twinsun.com>
2222
2223 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
2224 $(top_srcdir)/lib and ../lib. This fixes a bug reported
2225 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
2226 There's no need to mention top_builddir since Automake does that
2227 for us.
2228 (INCLUDES): Remove, as Automake says it's obsolescent.
2229 Contents migrated into AM_CPPFLAGS as described above.
2230 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
2231
2232 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
2233
2234 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
2235 (yyreportSyntaxError): Handle case where lookahead token is
2236 YYEMPTY.
2237
2238 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
2239
2240 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
2241 resulting parsers are compilable with C++.
2242
2243 2003-12-23 Paul Eggert <eggert@twinsun.com>
2244
2245 * config/depcomp, config/install-sh: Sync with Automake 1.8.
2246 * src/output.c (output_skeleton): Rename local var.
2247 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
2248 Bison tokens, as this runs afoul of the 2003-10-07 change that
2249 disallowed NUL bytes in character constants or string literals.
2250
2251 * tests/local.at: Require Autoconf 2.59's Autotest.
2252 * tests/testsuite.at: Don't include local.at, since we now assume
2253 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
2254 including it.
2255 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
2256 multiple inclusion warnings.
2257
2258 2003-12-02 Akim Demaille <akim@epita.fr>
2259

2267
2268 2003-10-07 Paul Eggert <eggert@twinsun.com>
2269
2270 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
2271 if testsuite doesn't exist.
2272
2273 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
2274 literals, unfortunately.
2275 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
2276 Complain about NUL bytes in character constants or string literals.
2277
2278 2003-10-05 Paul Eggert <eggert@twinsun.com>
2279
2280 * NEWS: Don't document %no-default-prec, as it's still
2281 too experimental.
2282 * doc/bison.texinfo: Document %no-default-prec only if
2283 the defaultprec flag is set. Normally it's not.
2284
2285 2003-10-04 Paul Eggert <eggert@twinsun.com>
2286
2287 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
2288 non-modifiable lvalue, instead of a modifiable one.
2289 * doc/bison.texinfo (Actions): Document that $$ can
2290 be assigned to. Do not claim that $$ and $N are
2291 array element references: user code should not rely on this.
2292
2293 2003-10-01 Paul Eggert <eggert@twinsun.com>
2294
2295 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
2296 (grammar_declaration): Use it.
2297 * src/scan-gram.l: New token %no-default-prec.
2298 * tests/conflicts.at: Revamp tests to use %no-default-prec.
2299 * NEWS, doc/bison.texinfo: Document the above.
2300
2301 2003-10-01 Akim Demaille <akim@epita.fr>
2302
2303 VCG no longer supports long_straight_phase.
2304
2305 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
2306 * src/print_graph.c (print_graph): Adjust.
2307
2308 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
2309 and Paul Eggert <eggert@twinsun.com>

2321
2322 2003-09-30 Paul Eggert <eggert@twinsun.com>
2323
2324 * tests/testsuite.at: Include local.at, not input.at, fixing
2325 a typo in the 2003-08-25 patch.
2326
2327 2003-08-27 Akim Demaille <akim@epita.fr>
2328
2329 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
2330 GCC warnings.
2331
2332 2003-08-26 Akim Demaille <akim@epita.fr>
2333
2334 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
2335 "<\#" to avoid magic from Gnus when posting parts of this script.
2336
2337 2003-08-26 Akim Demaille <akim@epita.fr>
2338
2339 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
2340 (Parser::parse): here.
2341 Adjust: nerrs and errstatus is now replaced by...
2342 (Parser::nerrs_, Parser::errstatus_): New.

2349 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
2350
2351 2003-08-25 Akim Demaille <akim@epita.fr>
2352
2353 When reducing initial empty rules, Bison parser read an initial
2354 location that is not defined. This results in garbage, and that
2355 affects Bison's own parser. Therefore we need (i) to extend Bison
2356 to support a means to initialize this location, and (ii) to use
2357 this CVS Bison to fix CVS Bison's parser.
2358
2359 * src/reader.h, reader.c (epilogue_augment): Remove, replace
2360 with...
2361 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
2362 * src/parse-gram.y: Adjust.
2363 (%initial-action): New.
2364 (%error-verbose): Since we require CVS Bison, there is no reason
2365 not to use it.
2366 * src/scan-gram.l: Adjust.
2367 * src/Makefile.am (YACC): New, to make sure we use our own parser.
2368 * data/yacc.c (yyparse): Use b4_initial_action.
2369
2370 2003-08-25 Akim Demaille <akim@epita.fr>
2371
2372 * doc/bison.texinfo: Don't promote stdout for error messages.
2373
2374 2003-08-25 Akim Demaille <akim@epita.fr>
2375
2376 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
2377 From Alexandre Duret-Lutz.
2378
2379 2003-08-25 Akim Demaille <akim@epita.fr>

2381 Version 1.875c.
2382
2383 2003-08-25 Akim Demaille <akim@epita.fr>
2384
2385 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
2386 Use them.
2387
2388 2003-08-25 Akim Demaille <akim@epita.fr>
2389
2390 * data/lalr1.cc (Parser::reduce_print_): New.
2391 Use it.
2392
2393 2003-08-25 Akim Demaille <akim@epita.fr>
2394
2395 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
2396 error recovery loops. This patch is based on
2397 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
2398 Also, augment the similarity between lalr1.cc and yacc.c.
2399 Note: the locations of error recovery rules are not correct yet.
2400
2401 * data/lalr1.cc: Comment changes to augment the similarity between
2402 lalr1.cc and yacc.c.
2403 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
2404 (yyerrlab1): Remove, but where it used to be (now the bottom part of
2405 yyerrlab), when hitting EOF, pop the whole stack here instead of
2406 merely falling thru the default error handling mechanism.
2407 (yyerrorlab): New label, with the old contents of YYERROR,
2408 plus the following change: pop the stack of rhs corresponding
2409 to the production that invoked YYERROR. That is how Yacc
2410 behaves (required by POSIX).
2411 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
2412 fail.
2413
2414 2003-08-25 Akim Demaille <akim@epita.fr>
2415
2416 Tune local.at so that people can "autom4te -l autotest calc.at -o
2417 calc" for instance, to extract a sub test suite.
2418
2419 * tests/testsuite.at: Move the initialization, Autotest version
2420 requirement, and AT_TESTED invocation into...
2421 * tests/local.at: here.
2422 * tests/testsuite.at: Include it for compatibility with Autoconf
2423 2.57.
2424 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
2425 be ignore.
2426
2427 2003-08-04 Paul Eggert <eggert@twinsun.com>
2428
2429 Rework code slightly to avoid gcc -Wtraditional warnings.
2430 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
2431 The returned value is now stored in *YY0. All callers changed.
2432 * src/output.c (merge_output): Adjust to the above change.
2433
2434 2003-07-26 Paul Eggert <eggert@twinsun.com>
2435
2436 * data/glr.c (YYASSERT): New macro.
2437 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
2438 yyresolveStates, yyprocessOneStack):
2439 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
2440 Derived from a suggestion by Frank Heckenbach.
2441
2442 2003-07-25 Paul Eggert <eggert@twinsun.com>
2443
2444 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
2445 for portability to K&R C (after ansi2knr, presumably). See
2446 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
2447 by Frank Heckenbach, though I have omitted the structure-initialization
2448 part of his glr-knr.diff patch since I recall that the Portable
2449 C Compiler didn't require that change.
2450
2451 Let the user specify how to allocate and free memory.
2452 Derived from a suggestion by Frank Heckenbach in
2453 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
2454 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
2455 All uses of free, malloc, realloc changed to use these macros,
2456 and unnecessary casts removed.
2457 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
2458
2459 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
2460
2461 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
2462 use s.empty() rather than s == "" to test for empty string; see
2463 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
2464 (trivial change)
2465

2470 2003-06-20 Paul Eggert <eggert@twinsun.com>
2471
2472 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
2473 and return properly parenthesized result.
2474 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
2475 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
2476 Remove unnecessary parentheses from uses.

2478 conventions for parentheses.
2479
2480 2003-06-19 Paul Eggert <eggert@twinsun.com>
2481
2482 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
2483 yyreportTree): Do not assume that size_t is the same width as int,
2484 when printing sizes. Print sizes using an unsigned format.
2485 Problem reported by Frank Heckenbach in
2486 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
2487
2488 Port to Forte Developer 7 C compiler.
2489 * data/glr.c (struct YYLTYPE): If locations are not being used,
2490 declare a single dummy member, as empty structs do not conform
2491 to the C standard.
2492 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
2493 the Forte Developer 7 C compiler complains that end-of-loop
2494 code is not reached.
2495
2496 2003-06-17 Paul Eggert <eggert@twinsun.com>
2497
2498 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
2499 avoid warnings from picky compilers about redefinition of PARAMS.
2500
2501 2003-06-17 Paul Eggert <eggert@twinsun.com>
2502
2503 Version 1.875b.
2504
2505 * NEWS: Document 1.875b.
2506
2507 * lib/bbitset.h: Do not include config.h; that's the includer's job.
2508 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
2509 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
2510 Don't use 'index' in comments, as it's a builtin fn on some hosts.
2511 * lib/bitset_stats.c: Include gettext.h unconditionally, as
2512 per recent gettext manual's suggestion.
2513 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
2514 Use prototypes, not old-style definitions.
2515 * lib/lbitset.c (lbitset_unused_clear): Likewise.
2516 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
2517 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
2518 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
2519 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
2520 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
2521 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
2522 vbitset_or_and_cmp, vbitset_copy): Likewise.
2523
2524 * lib/libiberty.h: Do not include config.h; that's the includer's job.
2525 Do not include <stdlib.h>.
2526 (PARAMS): Define unconditionally for C89.
2527 (ATTRIBUTE_NORETURN): Remove.
2528 (ATTRIBUTE_UNUSED): Define unconditionally.
2529
2530 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
2531 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
2532 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
2533 * lib/vbitset.c, lib/vbitset.h: New files.
2534 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
2535 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
2536 from libbitset.
2537
2538 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
2539 `How Can I Reset @code{yyparse}', since texinfo does not allow
2540 arbitrary @ in node names.
2541
2542 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
2543 shouldn't be needed according to the gettext 0.12.1 documentation
2544 but which seem to be needed anyway: codeset.m4 glibc21.m4
2545 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
2546 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
2547 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
2548
2549 * lib/.cvsignore: Add stdbool.h.
2550 * m4/.cvsignore: Add nls.m4, po.m4.
2551
2552 Upgrade to CVS gnulib.
2553 * stdbool_.h: File renamed from stdbool.h.in.
2554 * configure.ac (AM_STDBOOL_H): Invoke this instead of
2555 AC_HEADER_STDBOOL.
2556 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
2557 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
2558 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
2559 (MOSTLYCLEANFILES): New var.
2560 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
2561 (stdbool.h): New rule.
2562 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
2563 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
2564 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
2565 m4/quote.m4: Upgrade to today's gnulib.
2566
2567 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
2568 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
2569 the tests right now.
2570 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
2571 yyerror are declared before use; C99 requires this.
2572
2573 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
2574
2575 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
2576 first.
2577 (yyrecoverSyntaxError): Correct the logic for setting and testing
2578 yyerrState.
2579 Correct comment on handling EOF.
2580 Allow states with only a default reduction, rather than failing
2581 (I can't quite reconstruct why these were not allowed before).
2582
2583 Fixes to avoid problem that $-N rules in GLR parsers can cause
2584 buffer overruns, corrupting state.
2585
2586 * src/output.c (prepare_rules): Output max_left_semantic_context
2587 definition.
2588 * src/reader.h (max_left_semantic_context): New variable declaration.
2589 * src/scan-gram.l (max_left_semantic_context): Define.
2590 (handle_action_dollar): Update max_left_semantic_context.
2591 * data/glr.c (YYMAXLEFT): New definition.
2592 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
2593 (yyresolveAction): Ditto.
2594
2595 Fixes to problems with location handling in GLR parsers reported by
2596 Frank Heckenbach (2003/06/05).
2597
2598 * data/glr.c (YYLTYPE): Make trivial if locations not used.
2599 (YYRHSLOC): Add parentheses, and define only if locations used.
2600 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
2601 locations not used.
2602 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
2603 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
2604
2605 * tests/cxx-type.at: Exercise location information; update tests
2606 to differentiate output with and without locations.
2607 Remove forward declarations of yylex and yyerror---caused errors
2608 because default YYLTYPE not yet defined.
2609 Change semantic actions to compute strings, rather than printing
2610 them directly (to test proper passing of semantics values). Change
2611 output to prefix notation and update test data and expected results.
2612 (yylex): Track locations.
2613 (stmtMerge): Return value rather than printing, and include arguments
2614 in value.
2615
2616 2003-06-03 Paul Eggert <eggert@twinsun.com>
2617
2618 Avoid warnings generated by GCC 2.95.4 when Bison is
2619 configured with --enable-gcc-warnings.
2620 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
2621 yy::]b4_parser_class_name[::translate_,
2622 yy::Stack::operator[] (unsigned),
2623 yy::Stack::operator[] (unsigned) const,
2624 yy::Slice::operator[] (unsigned),
2625 yy::Slice::operator[] (unsigned) const):
2626 Rename local vars to avoid warnings.
2627 * tests/glr-regression.at (Improper handling of embedded actions
2628 and $-N in GLR parsers): Remove unused local variable from yylex.
2629 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
2630 (void) as arg when not pure, since we now assume C89 when building
2631 Bison. Pacify GCC by using parameter.
2632
2633 2003-06-02 Paul Eggert <eggert@twinsun.com>
2634
2635 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
2636 yy::Location::lines, yy::Location::columns): Rename arguments
2637 to avoid shadowing; this removes a warning generated by GCC 3.3.
2638
2639 2003-06-01 Paul Eggert <eggert@twinsun.com>
2640
2641 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
2642 to g++, as GCC 3.3 complains if you do it.
2643 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
2644 everything that WARNING_CFLAGS has, except omit warnings
2645 not suitable for C++.
2646 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
2647 * tests/atlocal.in (CXXFLAGS): New var.
2648 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
2649
2650 Fix a GLR parser bug I reported in February; see
2651 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
2652 The problem was that GLR parsers did not conform to the C standard,
2653 because actions like { $1 = $2 + $3; } expanded to expressions
2654 that invoked YYFILL in separate subexpressions, and YYFILL assigned
2655 to a local variable. The C standard says that expressions
2656 like (var = f ()) + (var = f ()) have undefined behavior.
2657 Another problem was that GCC sometimes issues warnings that
2658 yyfill and its parameters are unused.
2659
2660 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
2661 as possibly unused.
2662 (yyfill): New function.
2663 (YYFILL): Use it.
2664 (yyuserAction): Change type of yynormal to bool, so that it matches
2665 the new yyfill signature. Mark it as possibly unused.
2666
2667
2668 Follow up on a bug I reported in February, where a Bison-generated
2669 parser can loop. Provide a test case and a fix for yacc.c. I
2670 don't have a fix for lalr1.cc or for glr.c, unfortunately.
2671 The original bug report is in:
2672 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
2673
2674 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
2675 macro's size was becoming unwieldy.
2676 (yyerrlab): Do not discard an empty lookahead symbol, as this
2677 might destroy garbage.
2678 (yyerrorlab): New label, with the old contents of YYERROR,
2679 plus the following change: pop the stack of rhs corresponding
2680 to the production that invoked YYERROR. That is how Yacc
2681 behaves, and POSIX requires this behavior.
2682 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
2683 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
2684 Define 'alarm' to do nothing if unistd.h is not available.
2685 Add a new rule "exp: '-' error;" to test the above change to
2686 data/yacc.c. Use 'alarm' to abort any test taking longer than
2687 10 seconds, as it's probably looping.
2688 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
2689 Also, the new yacc.c generates two fewer diagnostics for an
2690 existing test.
2691
2692 2003-05-24 Paul Eggert <eggert@twinsun.com>
2693
2694 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
2695 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
2696 This fixes a problem reported by John Bowman when the Compaq/HP
2697 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
2698 -ansi -Wall -gall).
2699 * data/yacc.c (union yyalloc): Likewise.
2700 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
2701
2702 Switch from 'int' to 'bool' where that makes sense.
2703
2704 * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p,
2705 abitset_subset_p, abitset_disjoint_p, abitset_and_cmp,
2706 abitset_andn_cmp, abitset_or_cmp, abitset_xor_cmp, abitset_and_or,
2707 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
2708 Return or accept bool, not int. All callers changed.
2709 * lib/bbitset.h: (bitset_toggle_, bitset_copy_, bitset_and_or_cmp_,
2710 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.

2712 bitset_copy_, bitset_op4_cmp, bitset_and_or_cmp_, bitset_andn_or_cmp_,
2713 bitset_or_and_cmp_): Likewise.
2714 * lib/bitset.h (bitset_test, bitset_only_set_p): Likewise.
2715 * lib/bitset_stats.c (bitset_stats_print, bitset_stats_toggle,
2716 bitset_stats_test, bitset_stats_empty_p, bitset_stats_disjoint_p,
2717 bitset_stats_equal_p, bitset_stats_subset_p, bitset_stats_and_cmp,
2718 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
2719 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
2720 bitset_stats_or_and_cmp): Likewise.
2721 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
2722 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
2723 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
2724 ebitset_xor_cmp): Likewise.
2725 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
2726 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
2727 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
2728 lbitset_xor_cmp): Likewise.
2729 * lib/bbitset.h: Include <stdbool.h>.
2730 (struct bitset_vtable): The following members now return bool, not
2731 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
2732 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
2733 or_and_cmp).
2734 * src/conflicts.c (count_rr_conflicts): Likewise.
2735 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
2736 All uses changed.
2737 * lib/ebitset.c (ebitset_obstack_init): Likewise.
2738 * lib/lbitset.c (lbitset_obstack_init): Likewise.
2739 * src/getargs.c (debug_flag, defines_flag, locations_flag,
2740 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
2741 graph_flag): Likewise.
2742 * src/getargs.h (debug_flag, defines_flag, locations_flag,
2743 no_lines_flag, no_parser_flag, token_table_flag, yacc_flag,
2744 graph_flag): Likewise.
2745 * src/output.c (error_verbose): Likewise.
2746 * src/output.h (error_verbose): Likewise.
2747 * src/reader.c (start_flag, typed): Likewise.
2748 * src/reader.h (typed): Likewise.
2749 * src/getargs.c (LOCATIONS_OPTION): New constant.
2750 (long_options, getargs): Use it.
2751 * src/lalr.c (build_relations): Use bool, not int.
2752 * src/nullable.c (nullable_compute): Likewise.
2753 * src/print.c (print_reductions): Likewise.
2754 * src/tables.c (action_row, pack_vector): Likewise.
2755 * src/muscle_tab.h (MUSCLE_INSERT_BOOL): New macro.
2756 * src/output.c (prepare): Use it.
2757 * src/output.c (token_definitions_output,
2758 symbol_destructors_output, symbol_destructors_output): Use string,
2759 not boolean integer, to keep track of whether to output separator.
2760 * src/print_graph.c (print_core): Likewise.
2761 * src/state.c (state_rule_lookaheads_print): Likewise.
2762
2763 * config/install-sh: Sync from automake 1.7.5.
2764
2765 2003-05-14 Paul Eggert <eggert@twinsun.com>
2766
2767 * src/parse-gram.y (rules_or_grammar_declaration): Require a
2768 semicolon after a grammar declaration, in the interest of possible
2769 future changes to the Bison input language.
2770 Do not allow a stray semicolon at the start of the grammar.
2771 (rhses.1): Allow one or more semicolons after any rule, including
2772 just before "|" as required by POSIX.
2773 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
2774 grammar.
2775
2776 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2777
2778 %parse-param support for lalr1.cc.
2779
2780 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
2781 b4_cc_constructor_calls, b4_cc_constructor_call,
2782 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
2783 definitions.
2784 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
2785 parse-param arguments.
2786 (yy::b4_parser_class_name): Declare instance variables to
2787 hold parse-param arguments.
2788 * tests/calc.at: s/value/semantic_value/ because value clashes
2789 with a member of yy::b4_parser_class_name. Adjust C++ code
2790 to handle %parse-param. Enable %parse-param test in C++.
2791
2792 2003-05-12 Paul Eggert <eggert@twinsun.com>
2793
2794 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
2795 English a bit. Fix fclose typo. Change "const char" to "char
2796 const", and use ANSI C rather than K&R for "main". Suggest
2797 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
2798 and suggest yy_switch_to_buffer.
2799
2800 2003-05-05 Paul Eggert <eggert@twinsun.com>
2801
2802 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
2803 C89. This avoids a diagnostic on compilers that define __STDC__
2804 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
2805 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
2806
2807 2003-05-03 Paul Eggert <eggert@twinsun.com>
2808
2809 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
2810 Do not overrun array bounds.
2811 This should fix a bug reported today by Olatunji Oluwabukunmi in
2812 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
2813
2814 2003-04-29 Akim Demaille <akim@epita.fr>
2815
2816 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
2817 * src/getargs.c, src/getargs.h: here, as bool, not int.
2818 (nondeterministic_parser): New.
2819 * src/parse-gram.y, src/scan-gram.l: Support
2820 %nondeterministic-parser.
2821 * src/output.c (prepare): Use nondeterministic_parser instead
2822 of glr_parser where appropriate.
2823 * src/tables.c (conflict_row, action_row, save_row)
2824 (token_actions, token_actions, pack_vector): Ditto.
2825
2826 2003-04-29 Akim Demaille <akim@epita.fr>
2827
2828 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
2829
2830 2003-04-29 Akim Demaille <akim@epita.fr>
2831
2832 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
2833 with %pure-parser and %locations to exercise the patch from Yakov
2834 Markovitch below.
2835
2836 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
2837
2838 * data/yacc.c: (b4_lex_param): Corrected for the case where
2839 %lex-param is provided and %pure-parser isn't.
2840
2841 2003-04-27 Paul Eggert <eggert@twinsun.com>
2842
2843 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
2844 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
2845 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
2846 if it is not defined.
2847 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
2848
2849 2003-04-26 Paul Eggert <eggert@twinsun.com>
2850
2851 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
2852 Declare to be of type suitable for the ninf value itself, not of
2853 type suitable for the corresponding table, since the latter might
2854 be unsigned but the ninf value might be negative. This fixes a
2855 bug reported by Alexandre Duret-Lutz in
2856 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
2857
2858 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
2859 invokes it. We shouldn't invoke it twice because it will attempt
2860 to put error.o in the archive twice. This fixes a glitch reported
2861 by Martin Mokrejs in
2862 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
2863
2864 2003-04-21 Paul Eggert <eggert@twinsun.com>
2865
2866 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
2867 to gnulib.
2868
2869 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
2870
2871 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
2872 Fix obvious typo that results in uncompilable GLR parsers
2873 when both %pure-parser and %locations are used. (trivial change)
2874
2875 2003-04-17 Paul Eggert <eggert@twinsun.com>
2876
2877 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
2878 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
2879 Do not insert the expected token via unput, as this runs afoul
2880 of a POSIX-compatibility bug in flex 2.5.31.
2881 All uses changed to BEGIN the parent state,
2882 since we no longer insert the expected token via unput.
2883 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
2884 that is no longer emitted after the above change.
2885
2886 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
2887 the first one. This change is from Paul Hilfinger, and it fixes
2888 regression reported by Werner Lemberg in
2889 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
2890
2891 (resolve_sr_conflict): Don't invoke state_errs_set
2892 unless one or more tokens have been explicitly made errors.
2893 Otherwise, the above change causes Bison to abort.
2894
2895 * tests/existing.at (GNU pic Grammar): New test case, taken from
2896 Lemberg's email.
2897
2898 2003-03-31 Akim Demaille <akim@epita.fr>
2899
2900 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
2901
2902 2003-03-31 Akim Demaille <akim@epita.fr>
2903
2904 * src/output.c (prepare_symbols): Avoid trailing spaces in the
2905 output.
2906
2907 2003-03-31 Akim Demaille <akim@epita.fr>
2908
2909 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
2910 From Paul Hilfinger.
2911
2912 2003-03-29 Akim Demaille <akim@epita.fr>
2913
2914 * m4/error.m4: Do not put under dynamic conditions some code which
2915 expansion is under static control.
2916
2917 2003-03-29 Akim Demaille <akim@epita.fr>
2918
2919 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
2920
2921 2003-03-29 Akim Demaille <akim@epita.fr>
2922
2923 * doc/bison.texinfo (Strings are Destroyed): New.
2924
2925 2003-03-13 Paul Eggert <eggert@twinsun.com>
2926
2927 * .cvsignore: Add configure.lineno.
2928 * src/.cvsignore: Add yacc.
2929 * tests/.cvsignore: Add testsuite.log.
2930 * doc/fdl.texi: Sync with latest FSF version.
2931
2932 2003-03-12 Paul Eggert <eggert@twinsun.com>
2933
2934 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
2935 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
2936 cursor, instead of leaving it undefined. This fixes a bug
2937 reported by Tim Van Holder in
2938 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
2939 * tests/input.at (Torturing the Scanner): Test the scanner on
2940 an empty input file, which was Tim Van Holder's test case.
2941
2942 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
2943 <sys/resource.h> can be included, include sys/time.h and
2944 sys/times.h first, if available. This works around the SunOS
2945 4.1.4 porting bug reported by Bruce Becker in
2946 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
2947
2948 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
2949 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
2950 AC_HEADER_SYS_WAIT.
2951
2952 Merge changes from gnulib. This was prompted because the CVS
2953 snapshot didn't build on Solaris 7 due to strnlen problems.
2954
2955 These changes need to be merged back into gnulib:
2956 * lib/hash.c: Include <stdbool.h> unconditionally.
2957 * m4/onceonly.m4 (m4_quote): New macro.
2958 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
2959 Quote AC_FOREACH variable-expansions properly.
2960 The 2003-01-03 obstack.h change also needs merging.
2961 {end of changes requiring merging}
2962

2973 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
2974 gnulib sources.
2975
2976 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
2977 Add.

2986 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
2987 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
2988 (jm_PREREQ_ARGMATCH): Remove.
2989 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
2990 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
2991
2992 * src/system.h: Include <stdbool.h> unconditionally.
2993
2994 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
2995 assuming at least C89 in the bitset code for some time now.
2996
2997 2003-03-03 Akim Demaille <akim@epita.fr>
2998
2999 * ro.po: New.
3000
3001 2003-03-02 Akim Demaille <akim@epita.fr>
3002
3003 * doc/bison.texinfo (Table of Symbols): Reactivate the
3004 documentation for %lex-param, and %parse-param.
3005
3006 2003-03-02 Akim Demaille <akim@epita.fr>
3007
3008 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
3009 generate verbose error messages.
3010 Use the number of tokens as an upper bound in yytname, as it
3011 cannot be a non terminal.
3012
3013 2003-03-02 Akim Demaille <akim@epita.fr>
3014
3015 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
3016 message.
3017
3018 2003-03-02 Akim Demaille <akim@epita.fr>
3019
3020 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
3021 Use them to exercise yycheck overrun.
3022 Based on Andrew Suffield's grammar.
3023
3024 2003-03-02 Akim Demaille <akim@epita.fr>
3025
3026 Create tests/local.at for Bison generic testing macros.
3027
3028 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
3029 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
3030 This new file.
3031 * tests/calc.at (AT_CHECK_CALC): Adjust.
3032 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
3033 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
3034 * tests/local.at: here.
3035 (AT_COMPILE_CXX): Tags the tests using it as c++.
3036 Ignore the test if CXX is not functional.
3037
3038 2003-03-01 Paul Eggert <eggert@twinsun.com>
3039
3040 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
3041 not loc->end, since loc->end might contain garbage and this leads
3042 to undefined behavior on some platforms.
3043 (id_loc, token_start): Use (IF_LINTed) initial values that do not
3044 depend on *loc, so that the reader doesn't give the the false
3045 impression that *loc is initialized.
3046 (<INITIAL>"%%"): Do not bother setting code_start, since its value
3047 does not survive the return.
3048
3049 2003-03-01 Akim Demaille <akim@epita.fr>
3050
3051 * src/scan-gram.l (code_start): Always initialize it when entering
3052 into yylex, as SC_EPILOGUE is activated *before* the corresponding
3053 yylex invocation. An alternative would be making it static, but
3054 then it starts with the second %%'s beginning, instead of its end.
3055
3056 2003-02-28 Paul Eggert <eggert@twinsun.com>
3057
3058 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
3059 around a UnixWare 7.1.1 porting bug reported by John Hughes in
3060 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
3061
3062 2003-02-26 Paul Eggert <eggert@twinsun.com>
3063
3064 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
3065 Remove Sequent/Pyramid discussion (nobody uses them any more).
3066 Merge VMS and MS-DOS discussion; these ports may well be dead
3067 but let's keep mentioning them for now. Put <> around email
3068 addresses. Add copyright notice.
3069
3070 2003-02-24 Paul Eggert <eggert@twinsun.com>
3071
3072 * data/glr.c (yy_reduce_print): yylineno -> yylno,
3073 to avoid collision with flex use of yylineno.
3074 Problem reported by Bruce Lilly in
3075 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.

3081 2003-02-21 Akim Demaille <akim@epita.fr>
3082
3083 * data/lalr1.cc: Use temporary variables instead of casts to
3084 change integer types.
3085 Suggested by Paul Eggert.
3086
3087 2003-02-21 Akim Demaille <akim@epita.fr>
3088
3089 * doc/bison.texinfo: Use "location" consistently to refer to @n,
3090 to avoid confusions with lalr1.cc's notion of Position.
3091 Suggested by Paul Eggert.
3092
3093 2003-02-20 Akim Demaille <akim@epita.fr>
3094
3095 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
3096 before initial_columns.
3097 (location.hh): Use consistent variable names when defining the
3098 operator<<.
3099 Use "last" so that we subtract from Positions, not from unsigned.
3100
3101 2003-02-20 Akim Demaille <akim@epita.fr>
3102
3103 * data/lalr1.cc (position.hh): New subfile, including the extended
3104 and Doxygen'ed documentation of class Position.

3115 not defined.
3116 Don't use the location in yy::Parser::error_ and
3117 yy::Parser::print_ when not %locations.
3118 Activate more lalr1.cc tests.
3119
3120 2003-02-19 Akim Demaille <akim@epita.fr>
3121
3122 * data/lalr1.cc: When displaying a line number, be sure to make it
3123 an int.
3124

3126
3127 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):

3141
3142 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
3143 * tests/testsuite.at (AT_COMPILE): Use them.
3144 This fixes the testsuite problem reported by Robert Lentz in
3145 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
3146
3147 2003-02-12 Paul Eggert <eggert@twinsun.com>
3148
3149 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
3150 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
3151 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
3152 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
3153 Check for malloc failure, for consistency with yacc.c.
3154 (yytname_size): Remove, for consistency with yacc.c.
3155
3156 The bug still remains in data/lalr1.cc, as I didn't have time
3157 to fix it there.
3158
3159 2003-02-06 Akim Demaille <akim@epita.fr>
3160
3161 * configure.ac (GXX): Rename as...

3173 iterator names.
3174 (operator<< (Location)): New.
3175 * tests/atlocal.in (CXX): New.
3176 * tests/testsuite.at (AT_COMPILE_CXX): New.

3180 lalr1.cc is used.
3181 Adjust the C locations to match those from Emacs: first column is
3182 column 0.
3183 Change all the expected results.
3184 Conform to the GCS: simplify the locations when applicable.
3185 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
3186 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
3187 these CPP macros with the m4 macros new defined by...

3197
3198 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
3199 Location as is defined.
3200
3201 2003-02-04 Akim Demaille <akim@epita.fr>
3202
3203 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
3204 name_ being defined.
3205
3206 2003-02-03 Paul Eggert <eggert@twinsun.com>
3207
3208 * src/gram.h (start_symbol): Remove unused decl.
3209
3210 Use more-consistent naming conventions for local vars.
3211
3212 * src/derives.c (derives_compute): Change type of local var from
3213 int to rule_number.
3214 * src/gram.c (grammar_rules_partial_print): Likewise.

3241
3242 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):

3255 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
3256 param to have same name as that of enum, so that we don't use

3259 2003-02-02 Akim Demaille <akim@epita.fr>
3260
3261 * src/scan-skel.l: Scan more than one inert character per yylex
3262 invocation.
3263
3264 2003-02-01 Paul Eggert <eggert@twinsun.com>
3265
3266 Version 1.875a.
3267
3268 * po/LINGUAS: Add ms.
3269
3270 2003-01-30 Akim Demaille <akim@epita.fr>
3271
3272 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
3273
3274 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
3275
3276 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
3277 of $1.
3278
3279 Changes in response to error report by S. Eken: GLR mode does not
3280 handle negative $ indices or $ indices in embedded rules correctly.
3281 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
3282
3283 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
3284 (b4_rhs_location): Ditto.
3285 (yyfill): New function to copy from stack tree into array
3286 incrementally.
3287 (yyuserAction): Modify to allow incremental move of semantic values
3288 to rhs array when in GLR mode.
3289 Define YYFILL to use in user-defined actions to fill semantic array
3290 as needed.
3291 Remove dummy use of yystack, as there is now a guaranteed use.
3292 (yydoAction): Modify to allow incremental move of semantic values
3293 to rhs array when in GLR mode.
3294 (yyresolveAction): Ditto.
3295 (yyglrShiftDefer): Update comment.
3296 (yyresolveStates): Use X == NULL for pointers, not !X.
3297 (yyglrReduce): Ditto.
3298 (yydoAction): Ditto
3299
3300 * tests/glr-regr1.at: Rename to ...
3301 * tests/glr-regression.at: Add new regression test for the problems
3302 described above (adapted from S. Eken).
3303 Update copyright notice.
3304 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
3305 * tests/Makefile.am: Ditto.
3306
3307 2003-01-28 Paul Eggert <eggert@twinsun.com>
3308
3309 * data/lalr1.cc: Do not use @output_header_name@ unless
3310 b4_defines_flag is set. This fixes two bugs reported by
3311 Tim Van Holder in
3312 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
3313 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
3314
3315 2003-01-21 Paul Eggert <eggert@twinsun.com>
3316
3317 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
3318 we don't need to worry about yyerrlab1 being reported as an
3319 "unused label" by non-GCC C compilers. The downside is that if
3320 locations are used then a couple of statements are duplicated each
3321 time YYERROR is invoked, but the upside is that the warnings
3322 should vanish.
3323 (yyerrlab1): Move code to YERROR.
3324 (yyerrlab2): Remove. Change uses back to yyerrlab1.
3325 This reverts some of the 2002-12-27 change.
3326
3327 2003-01-17 Paul Eggert <eggert@twinsun.com>
3328
3329 * src/output.c (symbol_printers_output): Fix typo that led
3330 to core dump. Problem reported by Antonio Rus in
3331 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
3332
3333 2003-01-13 Akim Demaille <akim@epita.fr>,
3334 Quoc Peyrot <chojin@lrde.epita.fr>,
3335 Robert Anisko <anisko_r@lrde.epita.fr>
3336
3337 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
3338 when the stacks contain one element, as the loop would otherwise
3339 free the last state, and then use the top state (the one we just
3340 popped). This means that the initial elements will not be freed
3341 explicitly, as is the case in yacc.c; it is not a problem, as
3342 these elements have fake values.
3343
3344 2003-01-11 Paul Eggert <eggert@twinsun.com>
3345
3346 * NEWS: %expect-violations are now just warnings, reverting
3347 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
3348 bootstrapping problem reported by Matthias Klose; see
3349 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
3350 * src/conflicts.c (conflicts_print): Likewise.
3351 * tests/conflicts.at (%expect not enough, %expect too much,
3352 %expect with reduce conflicts): Likewise.
3353 * doc/bison.texinfo (Expect Decl): Document this. Also mention
3354 that the warning is enabled if the number of conflicts changes
3355 (not necessarily increases).
3356
3357 * src/getargs.c (version): Update copyright year.
3358
3359 2003-01-09 Akim Demaille <akim@epita.fr>
3360
3361 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
3362
3363 2003-01-08 Paul Eggert <eggert@twinsun.com>
3364
3365 * Makefile.maint (WGETFLAGS):
3366 New macro, containing "-C off" to disable proxy caches.
3367 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
3368 (rel-check): Use $(WGET) instead of wget.
3369
3370 2003-01-06 Paul Eggert <eggert@twinsun.com>
3371
3372 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
3373 the GLR paper of Scott, Johnstone and Hussain.
3374
3375 2003-01-04 Paul Eggert <eggert@twinsun.com>
3376
3377 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
3378 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
3379 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
3380 (EXTRA_LIBRARIES): New var, for liby.a.
3381 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
3382 (EXTRA_SCRIPTS): New var, for yacc.
3383
3384 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
3385 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
3386 Problem reported by Nelson H. F. Beebe.
3387
3388 2003-01-03 Paul Eggert <eggert@twinsun.com>
3389
3390 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
3391 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
3392 when compiling Bison 1.875's `bitset bset = obstack_alloc
3393 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
3394
3395 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
3396 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
3397 grow to a huge size with typical invocation.
3398
3399 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
3400 Use the pattern recommended by Autoconf 2.57, except also protect
3401 against double-definition.
3402 * src/system.h: Likewise.
3403 Portability issues reported by Nelson H. F. Beebe.
3404
3405 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
3406 All uses changed. Provide a definition in both C and C++.
3407 (yytrue, yyfalse): Define even if defined (__cplusplus).
3408
3409 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
3410 Reported by Nelson H. F. Beebe.
3411
3412 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
3413
3414 2003-01-02 Paul Eggert <eggert@twinsun.com>
3415
3416 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
3417 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
3418 Bug reported by Nelson H. F. Beebe.
3419
3420 2003-01-01 Paul Eggert <eggert@twinsun.com>
3421
3422 * Version 1.875.
3423
3424 2002-12-30 Paul Eggert <eggert@twinsun.com>
3425
3426 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
3427 Moved here from...
3428 (<INITIAL>","): Here. This causes stray "," to be treated
3429 more uniformly.
3430
3431 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
3432 last brace in braced code when not in Yacc mode, for compatibility
3433 with Bison 1.35. This resurrects the 2001-12-15 patch to
3434 src/reader.c.
3435
3436 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
3437 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
3438
3439 2002-12-28 Paul Eggert <eggert@twinsun.com>
3440
3441 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
3442 that of SYM's type. This fixes Debian bug 168069, reported by
3443 Thomas Olsson.
3444
3445 2002-12-28 Paul Eggert <eggert@twinsun.com>
3446
3447 Version 1.75f.
3448
3449 Switch back to the Yacc style of conflict reports, undoing some
3450 of the 2002-07-30 change.
3451 * doc/bison.texinfo (Understanding): Use Yacc style for
3452 conflict reports. Also, use new way of locating rules.
3453 * src/conflicts.c (conflict_report):
3454 Renamed from conflict_report_yacc, removing the old
3455 'conflict_report'. Translate the entire conflict report at once,
3456 so that we don't assume that "," has the same interpretation in
3457 all languages.
3458 (conflicts_output): Use Yacc-style conflict report for each state,
3459 instead of our more-complicated style.
3460 (conflicts_print): Use Yacc-style conflict report, except print
3461 the input file name when not emulating Yacc.
3462 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
3463 Conflicted Reduction, %expect not enough, %expect too much,
3464 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
3465 * tests/existing.at (GNU Cim Grammar): Likewise.
3466 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
3467
3468 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
3469 fatal): Don't invoke fflush; it's not needed and it might even be
3470 harmful for stdout, as stdout might not be open.
3471 * src/reduce.c (reduce_print): Likewise.
3472
3473 2002-12-27 Paul Eggert <eggert@twinsun.com>
3474
3475 Fix a bug where error locations were not being recorded correctly.
3476 This problem was originally reported by Paul Hilfinger in
3477 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
3478
3479 * data/yacc.c (yyparse): New local var yylerrsp, to record the
3480 top of the location stack's error locations.
3481 (yyerrlab): Set it. When discarding a token, push its location
3482 onto yylerrsp so that we don't lose track of the error's end.
3483 (yyerrlab1): Now is only the target of YYERROR, so that we can
3484 properly record the location of the action that failed. For GCC
3485 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
3486 GCC warning about yyerrlab1 being unused if YYERROR is unused.
3487 (yyerrlab2): New label, which yyerrlab now falls through to.
3488 Compute the error's location by applying YYLLOC_DEFAULT to
3489 the locations of all the symbols that went into the error.
3490 * doc/bison.texinfo (Location Default Action): Mention that
3491 YYLLOC_DEFAULT is also invoked for syntax errors.
3492 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
3493 Error locations include the locations of all the tokens that were
3494 discarded, not just the last token.
3495
3496 2002-12-26 Paul Eggert <eggert@twinsun.com>
3497
3498 * src/files.c: Include quote.h.
3499 (compute_output_file_names): Warn if we detect conflicting
3500 outputs to the same file. This should catch the misunderstanding
3501 exemplified by Debian Bug 165349, reported by Bruce Stephens..
3502
3503 * src/conflicts.c (conflicts_print): If the user specifies
3504 "%expect N", report an error if there are any reduce/reduce
3505 conflicts. This is what the manual says should happen.
3506 This fixes Debian bug 130890, reported by Anthony DeRobertis.
3507 * tests/conflicts.at (%expect with reduce conflicts): New test.
3508
3509 Don't use m4_include on relative file names, as it doesn't work as
3510 desired if there happens to be a file with that name under ".".
3511
3512 * m4sugar/version.m4: Remove; it was included but it wasn't used.
3513 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
3514 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
3515 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
3516 * src/output.c (output_skeleton): Use full path names when
3517 specifying a file to include; don't rely on include path, as
3518 it's unreliable when the working file contains a file with
3519 that name.
3520
3521 2002-12-25 Paul Eggert <eggert@twinsun.com>
3522
3523 Remove obsolete references to bison.simple and bison.hairy.
3524 Problem mentioned by Aubin Mahe in
3525 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
3526 * data/glr.c: Comment fix.
3527 * doc/bison.1: Remove references. Also, mention "yacc".
3528
3529 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
3530 with -g option.
3531
3532 * src/parse-gram.y (declaration): Use enum "report_states" rather
3533 than its numeric value 1.
3534
3535 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
3536 opening a new one. This fixes Debian bug 165349, reported by
3537 Bruce Stephens.
3538
3539 2002-12-24 Paul Eggert <eggert@twinsun.com>
3540
3541 Version 1.75e.
3542
3543 * Makefile.maint (cvs-update): Don't assume that the shell
3544 supports $(...), as Solaris sh doesn't.
3545
3546 * src/parse-gram.y (lloc_default): Remove test for empty
3547 nonterminals at the end, since it didn't change the result.
3548
3549 2002-12-24 Paul Eggert <eggert@twinsun.com>
3550
3551 If the user does not define YYSTYPE as a macro, Bison now declares it
3552 using typedef instead of defining it as a macro. POSIX requires this.
3553 For consistency, YYLTYPE is also declared instead of defined.
3554
3555 %union directives can now have a tag before the `{', e.g., the
3556 directive `%union foo {...}' now generates the C code
3557 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
3558 The default union tag is `YYSTYPE', for compatibility with Solaris 9
3559 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
3560 instead of `yyltype'.
3561
3562 `yystype' and `yyltype' are now obsolescent macros instead of being
3563 typedefs or tags; they are no longer documented and will be
3564 withdrawn in a future release.
3565
3566 * data/glr.c (b4_location_type): Remove.
3567 (YYSTYPE): Renamed from yystype.
3568 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
3569 (struct YYLTYPE): Renamed from struct yyltype.
3570 (YYLTYPE): Renamed from yyltype.
3571 (yyltype, yystype): New (and obsolescent) macros,
3572 for backward compatibility.
3573 * data/yacc.c: Likewise.
3574
3575 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
3576 does not specify a union tag. This is for compatibility with
3577 Solaris 9 yacc.
3578
3579 * src/parse-gram.y (add_param): 2nd arg is now char * not char
3580 const *, since it is now modified by stripping surrounding { }.
3581 (current_braced_code): Remove.
3582 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
3583 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
3584 trailing " {...}". Now of type <chars>.
3585 (grammar_declaration): Adjust to bundled tokens.
3586 (code_content): Remove; stripping is now done by add_param.
3587 (print_token_value): Print contents of bundled tokens.
3588 (token_name): New function.
3589
3590 * src/reader.h (braced_code, current_braced_code): Remove.
3591 (token_name): New decl.
3592
3593 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
3594 token_type, not braced_code code_kind. All uses changed.
3595 (SC_PRE_CODE): New state, for scanning after a keyword that
3596 has (or usually has) an immediately-following braced code.
3597 (token_type): New local var, to keep track of which token type
3598 to return when scanning braced code.
3599 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
3600 <INITIAL>"%parse-param", <INITIAL>"%printer",
3601 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
3602 instead of returning a token type immediately.
3603 (<INITIAL>"{"): Set token type.
3604 (<SC_BRACED_CODE>"}"): Use it.
3605 (handle_action_dollar, handle_action_at): Now returns bool
3606 indicating success. Fail if ! current_rule; this prevents a core dump.
3607 (handle_symbol_code_dollar, handle_symbol_code_at):
3608 Remove; merge body into caller.
3609 (handle_dollar, handle_at): Complain in invalid contexts.
3610
3611 * NEWS, doc/bison.texinfo: Document the above.
3612 * NEWS: Fix years and program names in copyright notice.
3613
3614 2002-12-17 Paul Eggert <eggert@twinsun.com>
3615
3616 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
3617 Reporting, Table of Symbols): Omit mentions of %lex-param and
3618 %parse-param from the documentation for now.
3619
3620 2002-12-15 Paul Eggert <eggert@twinsun.com>
3621
3622 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
3623 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
3624 lookahead symbol, and which sets yychar in parser actions) and it
3625 disagreed with the Bison documentation. Bug
3626 reported by Andrew Walrond.
3627
3628 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
3629 as the caller now does that.
3630 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
3631 (YYEMPTY): Parenthesize right hand side, since others use it.
3632 (yyparse): Don't assume that our generated code is the only code
3633 that sets yychar.
3634
3635 2002-12-13 Paul Eggert <eggert@twinsun.com>
3636
3637 Version 1.75d.
3638
3639 POSIX requires a "yacc" command.
3640 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
3641 (MOSTLYCLEANFILES): Add yacc.
3642 (yacc): New rule.
3643 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
3644 as an alias for bison y.
3645
3646 * po/LINGUAS: Add da.
3647
3648 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
3649 problem with latest <getopt.h>.
3650 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
3651
3652 * doc/fdl.texi: Upgrade to 1.2.
3653 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
3654 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
3655 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
3656 gnulib.
3657 * config/install-sh: Sync with autotools.
3658
3659 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
3660 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
3661 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
3662 locations are requested.
3663 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
3664 locations are requested.
3665
3666 2002-12-12 Paul Eggert <eggert@twinsun.com>
3667
3668 Remove unportable casts and storage allocation tricks.
3669 While we're at it, remove almost all casts, since they
3670 usually aren't needed and are a sign of trouble.
3671
3672 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
3673
3674 * src/derives.c (derives_compute): Do not subtract NTOKENS from
3675 the pointer DSET returned by malloc; this isn't portable.
3676 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
3677 Similarly for DERIVES.
3678 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
3679 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
3680 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
3681
3682 * src/derives.c (derives_compute): Do not bother invoking
3683 int_of_rule_number, since rule numbers are integers.
3684
3685 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
3686 rather than XMALLOC (char, N).
3687
3688 * src/files.c (filename_split): Rewrite to avoid cast.
3689
3690 * src/gram.h (symbol_number_as_item_number,
3691 item_number_as_symbol_number, rule_number_as_item_number,
3692 item_number_as_rule_number):
3693 Now inline functions rather than macros, to avoid casts.
3694 * src/state.h (state_number_as_int): Likewise.
3695 * src/tables.c (state_number_to_vector_number,
3696 symbol_number_to_vector_number): Likewise.
3697
3698 * src/gram.h (int_of_rule_number): Remove; no longer used.
3699
3700 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
3701 since the resulting storage is always stored into.
3702
3703 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
3704 where it's needed.
3705
3706 * src/muscle_tab.c (muscle_m4_output):
3707 Now inline. Return bool, not int.
3708 * src/state.c (state_compare): Likewise.
3709 * src/symtab.c (symbol_check_defined,
3710 symbol_check_alias_consistency, symbol_pack, symbol_translation,
3711 hash_compare_symbol, hash_symbol):
3712 Likewise.
3713 * src/uniqstr.c (uniqstr_print): Likewise.
3714 * src/muscle_tab.c (muscle_m4_output_processor):
3715 New function, to avoid casts.
3716 * src/state.c (state_comparator, stage_hasher): Likewise.
3717 * src/symtab.c (symbol_check_defined_processor,
3718 symbol_check_alias_consistency_processor, symbol_pack_processor,
3719 symbol_translation_processor, hash_symbol_comparator,
3720 hash_symbol_hasher): Likewise.
3721 * src/uniqstr.c (uniqstr_print_processor): Likewise.
3722 * src/muscle_tab.c (muscles_m4_output):
3723 Use new functions instead of casting old functions unportably.
3724 * src/state.c (state_hash_new): Likewise.
3725 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
3726 symbols_token_translations_init):
3727 Likewise.
3728 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
3729
3730 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
3731 var instead of casting to long, to avoid casts.
3732 (prepare_states): Use MALLOC rather than alloca, so that we don't
3733 have to worry about alloca.
3734 * src/state.c (state_hash_lookup): Likewise.
3735
3736 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
3737 local var instead of casting to unsigned char, to avoid casts.
3738
3739 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
3740 STATE_ALLOC): Remove.
3741 (transitions_new, errs_new, reductions_new, state_new): Use malloc
3742 rather than calloc, and use offsetof to avoid allocating slightly
3743 too much storage.
3744 (state_new): Initialize all members.
3745

3747
3748 * src/symtab.c (symbol_free): Remove; unused.

3754 (symbol_processor): Remove.
3755 (symbols_do): Remove decl; now static.

3759 (<inttypes.>, <stdint.h>): Include if available.
3760 (uintptr_t): New type, if system lacks it.

3763 new macros.
3764
3765 * src/tables.c (table_size): Now int, to pacify GCC.
3766 (table_grow, table_ninf_remap): Use signed table size.

3777
3778 2002-12-09 Paul Eggert <eggert@twinsun.com>
3779
3780 Change identifier spellings to avoid collisions with names
3781 that are reserved by POSIX.
3782
3783 Don't use names ending in _t, since POSIX reserves them.
3784 For consistency, remove _e and _s endings -- they're weren't
3785 needed to remove ambiguity. All uses changed.
3786 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
3787 turn was just renamed from struniq_t.
3788 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
3789 which in turn was just renamed from struniq_processor_t.

3861 value_t_as_yystype -> value_as_yystype.
3862
3863 Don't include <errno.h> in the mainstream code, since it
3864 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
3865 * lib/get-errno.c, lib/get-errno.h: New files.
3866 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
3867 get-errno.c.

3876 (TAB_EXT): Renamed from EXT_TAB.
3877 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
3878
3879 Avoid str[a-z]*, since <string.h> reserves that name space.
3880 Change all instances of "struniq" in names to "uniqstr", and
3881 likewise for "STRUNIQ" and "UNIQSTR".
3882 * src/uniqstr.c: Renamed from src/struniq.c.
3883 * src/uniqstr.h: Renamed from src/struniq.h.

3906 (BASE_MINIMUM): Renamed from BASE_MIN.
3907 (ACTION_MAX): Remove; unused.
3908 (ACTION_NUMBER_MINIMUM): Renamed from ACTION_MIN.
3909 Unnecessary casts removed from above defines.
3910
3911
3912 Fix misspelling in names.
3913 * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e.
3914 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
3915 G_NODE_ALIGNEMENT.

3917
3918 * lib/timevar.c (timevar_report): Renamed from time_report,
3919 for consistency with other names.
3920 * lib/timevar.h (timevar_report): New decl.
3921 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
3922
3923
3924 Sort include-file uses.
3925
3926 Reorder all include files under src to be in the order "system.h".
3927 then the ../lib include files in angle brackets (alphabetized),
3928 then the . include files in double-quotes (alphabetized). Fix
3929 dependency breakages encountered in this process, as follows:
3930 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
3931 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
3932 * src/state.h: Include "symtab.h".
3933
3934 2002-12-08 Paul Eggert <eggert@twinsun.com>
3935
3936 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
3937 since this causes problems when __file__ contains character
3938 sequences like "@" that are treated specially by src/scan-skel.l.
3939 Instead, just use the file's basename. This fixes the bug
3940 reported by Martin Mokrejs in
3941 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
3942
3943 2002-12-06 Paul Eggert <eggert@twinsun.com>
3944
3945 Add support for rules that do not have trailing semicolons, as
3946 POSIX requires. Improve the quality of locations in Bison
3947 diagnostics.
3948
3949 * src/location.c: Include <quotearg.h>.
3950 (empty_location): Now const.
3951 (location_print): New function. Follow the recommendation of the
3952 GNU Coding Standards for locations that span file boundaries.
3953 * src/location.h: Do not include <quotearg.h>; no longer needed.
3954 (boundary): New type.
3955 (location_t): Use it. This allows locations to span file boundaries.
3956 All member uses changed: file -> start.file or end.file (as needed),
3957 first_line -> start.line, first_column -> start.column,
3958 last_line -> end.line, last_column -> end.column.
3959 (equal_boundaries): New function.
3960 (LOCATION_RESET, LOCATION_STEP): Remove.
3961 (LOCATION_PRINT): Remove. All callers changed to use location_print.
3962 (empty_location): Now const.
3963 (location_print): New decl.
3964 * src/parse-gram.y (lloc_default): New function, which handles
3965 empty locations more accurately.
3966 (YYLLOC_DEFAULT): Use it.
3967 (%token COLON): Remove.
3968 (%token ID_COLON): New token.
3969 (rules): Use it.
3970 (declarations, rules): Remove trailing semicolon.
3971 (declaration, rules_or_grammar_declaration):
3972 Allow empty (";") declaration.
3973 (symbol_def): Remove empty actions; no longer needed.
3974 (rules_or_grammar_declaration): Remove trailing semicolon.
3975 (semi_colon.opt): Remove.
3976 * src/reader.h: Include location.h.
3977 (scanner_cursor): New decl.
3978 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
3979 rolling our own.
3980 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
3981 of *loc.
3982 (STEP): Remove. No longer needed, now that adjust_location does
3983 the work. All uses removed.
3984 (scanner_cursor): New var.
3985 (adjust_location): Renamed from extend_location. It now sets
3986 *loc and adjusts the scanner cursor. All uses changed.
3987 Don't bother testing for CR.
3988 (handle_syncline): Remove location arg; now updates scanner cursor.
3989 All callers changed.
3990 (unexpected_end_of_file): Now accepts start boundary of token or
3991 comment, not location. All callers changed. Update scanner cursor,
3992 not the location.
3993 (SC_AFTER_IDENTIFIER): New state.
3994 (context_state): Renamed from c_context. All uses changed.
3995 (id_loc, code_start, token_start): New local vars.
3996 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
3997 processing of Yacc white space and equivalents here.
3998 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
3999 instead of returning ID immediately, since we need to search for
4000 a subsequent colon.
4001 (<INITIAL>"'", "\""): Save token_start.
4002 (<INITIAL>"%{", "{", "%%"): Save code_start.
4003 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
4004 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
4005 BEGIN context_state at end, not INITIAL.
4006 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
4007 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
4008 Return correct token start.
4009 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
4010 the start of a character, string or multiline comment is found.
4011 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
4012 Reduction): Adjust reported locations to match the more-precise
4013 results now expected.
4014 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
4015 * tests/reduce.at (Useless Rules, Reduced Automaton,
4016 Underivable Rules): Likewise.
4017 * tests/regression.at (Invalid inputs): No longer `expecting ";"
4018 or "|"' now that so many other tokens are allowed by the new grammar.
4019
4020 * src/complain.h (current_file): Remove duplicate decl;
4021 current_file is now owned by files.h.
4022 * src/complain.c, src/scan-gram.l: Include files.h.
4023
4024 2002-12-06 Paul Eggert <eggert@twinsun.com>
4025
4026 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
4027 promotes to int; it might be unsigned int.
4028 * data/yacc.c (yy_reduce_print): Likewise.
4029
4030 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
4031 be #defined in the prologue, not in the Bison declarations.
4032 This fixes Debian Bug 102878, reported by Shaul Karl.
4033
4034 2002-12-02 Paul Eggert <eggert@twinsun.com>
4035
4036 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
4037 * lib/strtoul.c: New file, from gnulib.
4038 This fixes a porting bug reported by Peter Klein in
4039 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
4040
4041 2002-11-30 Paul Eggert <eggert@twinsun.com>
4042
4043 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
4044 and put only a forward declaration in the prologue. This is for
4045 consistency with the other scanner helper functions.
4046
4047 Type clashes now generate warnings, not errors, since it
4048 appears that POSIX may allow some grammars with type clashes.
4049 * src/reader.c (grammar_current_rule_check): Warn about
4050 type clashes instead of complaining.
4051 * tests/input.at (Type Clashes): Expect warnings, not complaints.
4052
4053 Add Yacc library, since POSIX requires it.
4054 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
4055 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
4056 * lib/main.c, lib/yyerror.c: New files.
4057
4058 gram_error can be static; it need not be extern.
4059 * src/reader.h (gram_error): Remove decl.
4060 * src/parse-gram.y (gram_error): Now static. Add static decl.
4061 (print_token_value): Omit parameter names from forward decl,
4062 for consistency.
4063
4064 2002-11-29 Paul Eggert <eggert@twinsun.com>
4065
4066 * doc/bison.texinfo: Emphasize that yylex and yyerror must
4067 be declared before being used. E.g., one should typically
4068 declare them in the prologue. Use GNU coding style in examples.
4069 Put "const" consistently after the type it modifies. Mention
4070 that C99 supports "inline". Mention that yyerror traditionally
4071 returns "int".
4072
4073 %parse-param and %lex-param now take just one argument, the
4074 declaration; the argument name is deduced from the declaration.
4075
4076 * doc/bison.texinfo (Parser Function, Pure Calling, Error
4077 Reporting, Table of Symbols): Document this.
4078 * src/parse-gram.y (add_param): New function.
4079 (COMMA): Remove.
4080 (declaration): Implement new rule for %parse-param and %lex-param.
4081 * src/scan-gram.l: "," now elicits a warning, rather than being
4082 a token; this is more compatible with byacc.
4083 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
4084
4085 2002-11-27 Paul Eggert <eggert@twinsun.com>
4086
4087 Rename identifiers to avoid real and potential collisions.
4088
4089 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
4090 to avoid collision with lex macro described by Bruce Lilly in
4091 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
4092 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
4093 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
4094 * src/parse-gram.y (print_token_value): Renamed from yyprint.
4095 All uses changed.
4096 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
4097 The name "yycontrol" violates the name space rules, and this stuff
4098 wasn't being used anyway.
4099 (input): Remove action; this stuff wasn't being used.
4100 (gram_error): Rename local variable yylloc -> loc.
4101 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
4102 (YY_DECL): Don't use "yy" at start of local variables.
4103 All uses changed, e.g., yylloc -> loc.
4104 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
4105 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
4106 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
4107 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
4108
4109 * src/parse-gram.y (gram_error): loc is now const *.
4110 * src/reader.h (gram_error): Likewise.
4111
4112 2002-11-24 Paul Eggert <eggert@twinsun.com>
4113
4114 Version 1.75c.
4115
4116 * tests/actions.at (Actions after errors): Use an output format
4117 more similar to that of the Printers and Destructors test.
4118 Test the position of the ';' token too.
4119 (Printers and Destructors): Likewise.
4120 (Printers and Destructors: %glr-parser): Remove for now, to avoid
4121 unnecessarily alarming people when the test fails.
4122
4123 * data/yacc.c (yyerrlab1): Move this label down, so that the
4124 parser does not discard the lookahead token if the user code
4125 invokes YYERROR. This change is required for POSIX conformance.
4126
4127 * lib/error.c: Sync with gnulib.
4128
4129 2002-11-22 Paul Eggert <eggert@twinsun.com>
4130
4131 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
4132 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
4133 * lib/xmalloc.c: Likewise.
4134
4135 2002-11-20 Paul Eggert <eggert@twinsun.com>
4136
4137 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
4138
4139 2002-11-20 Paul Eggert <eggert@twinsun.com>
4140
4141 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
4142 should use `if (! x) abort ();' rather than `assert (x);', and
4143 anyway it's one less thing to worry about configuring.
4144
4145 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
4146 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
4147 and replace all instances of assert with abort.
4148 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
4149 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
4150
4151 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
4152 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
4153 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,

4172 (ARGMATCH_ASSERT): Use it.
4173
4174 * src/system.h (verify): New macro.

4176 rather than assert.
4177 * src/tables.c (tables_generate): Likewise.
4178
4179 * src/struniq.c (struniq_assert): Now returns void, and aborts

4183
4184 2002-11-18 Paul Eggert <eggert@twinsun.com>
4185
4186 * data/glr.c (yygetLRActions): Replace `yyindex' with
4187 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
4188 This fixes the regression with Sun ONE Studio 7 cc that I reported in
4189 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
4190
4191 2002-11-18 Akim Demaille <akim@epita.fr>
4192
4193 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
4194 space.
4195 From Tim Van Holder.
4196
4197 2002-11-17 Paul Eggert <eggert@twinsun.com>
4198
4199 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
4200 to "SyntaxError" for consistency with my 2002-11-15 change.
4201
4202 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
4203 not define to {}, since this breaks the common use of `YYDPRINTF
4204 ((...));' if a single statement is desired (e.g. before `else').
4205 Work around GCC warnings by surrounding corresponding calls with
4206 {} if needed.
4207 (yyhasResolvedValue): Remove unused function.
4208 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
4209 loop body.
4210 (yyreportSyntaxError): Renamed from yyreportParseError.
4211 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
4212 All uses changed.
4213 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
4214 extern when possible. Remove unused initializations.
4215
4216 2002-11-16 Akim Demaille <akim@epita.fr>
4217
4218 Augment the similarity between GLR and LALR traces.
4219
4220 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
4221 (YY_REDUCE_PRINT): New.
4222 (yyparse): Use them.
4223 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
4224 YYDPRINT here.
4225 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
4226 state reached after the reduction/recovery, since...
4227 (yyparse, yyprocessOneStack): Report the state we are entering in.
4228
4229 2002-11-16 Akim Demaille <akim@epita.fr>
4230
4231 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
4232 Add support for --trace=skeleton.
4233 * src/scan-skel.l: %option debug.
4234 Scan strings of non-@ or \n instead of character by character.
4235 (scan_skel): Handle trace_skeleton.
4236 (QPUTS): New.
4237 (@output_parser_name@, @output_header_name@): ``Restore'' their
4238 support (used to be M4 macros).
4239 * data/yacc.c: Quote larger chunks, a la glr.c.
4240 * data/lalr1.cc: Likewise.
4241 The header guards are no longer available, so use some other
4242 string than `YYLSP_NEEDED'.
4243
4244 2002-11-16 Akim Demaille <akim@epita.fr>
4245
4246 Make the ``Printers and Destructors'' test more verbose, taking
4247 `yacc.c''s behavior as (possibly wrong) reference.
4248
4249 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
4250 instead of fprint on stdout.
4251 Set and report the last_line of the symbols.
4252 Consistently display values and locations.
4253
4254 2002-11-16 Paul Eggert <eggert@twinsun.com>
4255
4256 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
4257
4258 2002-11-15 Paul Eggert <eggert@twinsun.com>
4259
4260 * tests/actions.at (Actions after errors): New test case.
4261
4262 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
4263 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
4264 tests/action.at, tests/calc.at, tests/conflicts.at,
4265 tests/cxx-type.at, tests/regression.at:
4266 "parse error" -> "syntax error" for POSIX compatibility.
4267 "parsing stack overflow..." -> "parser stack overflow" so
4268 that code matches Bison documentation.
4269
4270 2002-11-15 Akim Demaille <akim@epita.fr>
4271
4272 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
4273 take two BRACED_CODE, not two string_content.
4274 Free the scanner's obstack when we are done.
4275 (code_content): New.
4276 * tests/calc.at: Adjust.
4277 * doc/bison.texinfo: Adjust.
4278 Also, make sure to include the `,' for these declarations.
4279
4280 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
4281
4282 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
4283 definition; avoids potential autoreconf problems.
4284
4285 2002-11-15 Akim Demaille <akim@epita.fr>
4286
4287 Always check the value returned by yyparse.
4288
4289 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
4290 returned by yyparse.
4291 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
4292 Adjust calls.
4293 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
4294 returned by yyparse.
4295
4296 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4297
4298 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
4299 on input.at test.
4300
4301 2002-11-14 Paul Eggert <eggert@twinsun.com>
4302
4303 * src/output.c (output_skeleton): Call xfopen instead of
4304 duplicating xfopen's body.
4305
4306 Fix bugs reported by Nelson H. F. Beebe in
4307 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
4308
4309 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
4310 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
4311 Group compiler. Instead, use "$CC -E bar.c". Include the .h
4312 file twice in the grammar, as an extra check.
4313
4314 * tests/input.at (Torturing the Scanner): Surround the
4315 backslash-newline tests with "#if 0", to make it less likely that
4316 we'll run into compiler bugs. Bring back solitary \ inside
4317 comment, but add a closing comment to work around HP C bug. Don't
4318 test backslash-newline in C character constant.
4319
4320 2002-11-14 Akim Demaille <akim@epita.fr>
4321
4322 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
4323 status of the compiler.
4324 Calling `exit 1' is no longer needed.
4325 Reported by Nelson H. F. Beebe.
4326
4327 2002-11-14 Akim Demaille <akim@epita.fr>
4328
4329 * tests/atlocal.in (CPPFLAGS): We have config.h.
4330 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
4331 New.
4332 * tests/actions.at, tests/calc.at, tests/conflicts.at,
4333 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
4334 * tests/regression.at, tests/torture.at: Use them for all the
4335 grammars that are to be compiled.
4336 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
4337 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
4338 * doc/bison.texinfo (GLR Parsers): Document `inline'.
4339
4340 2002-11-14 Akim Demaille <akim@epita.fr>
4341
4342 * doc/bison.texinfo: Various formatting changes (alignments in
4343 samples, additional @group/@end group, GCS in samples.
4344 Use @deffn instead of simple @table to define the directives,
4345 macros, variables etc.
4346
4347 2002-11-13 Paul Eggert <eggert@twinsun.com>
4348
4349 Fix some bugs reported by Albert Chin-A-Young in
4350 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
4351
4352 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
4353 -o c"; the HP C compiler chatters during compilation.
4354 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
4355 * tests/headers.at (export YYLTYPE): Likewise.
4356
4357 * tests/input.at (Torturing the Scanner): Remove lines containing
4358 solitary backslashes, as they tickle a bug in the HP C compiler.
4359
4360 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
4361 comments, since they're not portable. Use GNU coding style.
4362
4363 2002-11-13 Akim Demaille <akim@epita.fr>
4364
4365 * data/yacc.c: Leave bigger chunks of quoted text.
4366 (YYDSYMPRINTF): New.
4367 Use it to report symbol activities.
4368 * data/glr.c (YYDSYMPRINTF): New.
4369 Use it.
4370
4371 2002-11-12 Paul Eggert <eggert@twinsun.com>
4372
4373 Version 1.75b.
4374
4375 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
4376 (yyglrReduce): Return yyok, not 0.
4377 This should avoid the enumerated-type warnings reported
4378 by Nelson H. F. Beebe in
4379 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
4380
4381 * lib/bbitset.h (BITSET_INLINE): Remove.
4382 * lib/bitset.h [! BITSET_INLINE]: Remove.
4383 (bitset_set, bitset_reset, bitset_test): Rename local vars
4384 to avoid shadowing warnings by GCC.
4385
4386 * data/glr.c (inline): Remove #define. It's the user's
4387 responsibility to #define it away, just like 'const'.
4388 This fixes one of the bugs reported by Nelson H. F. Beebe in
4389 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
4390
4391 * Makefile.maint (po-check): Scan .l and .y files instead of the
4392 .c and the .h files that they generate. This fixes the bug
4393 reported by Tim Van Holder in:
4394 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
4395 Look for N_ as well as for _. Try to avoid matching #define for
4396 N_ and _.
4397 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
4398 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
4399 * src/scan-gram.l: Revamp regular expressions so that " and '
4400 do not confuse xgettext.
4401
4402 * src/struniq.h (struniq_new): Do not declare the return type
4403 to be 'const'; this violates the C standard.
4404 * src/struniq.c (struniq_new): Likewise.
4405
4406 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
4407
4408 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
4409 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
4410 linker.
4411
4412 2002-11-12 Akim Demaille <akim@epita.fr>
4413
4414 * Makefile.maint: Sync with Autoconf:
4415 (local_updates): New.
4416
4417 2002-11-12 Akim Demaille <akim@epita.fr>
4418

4424 locations.
4425
4426 2002-11-12 Akim Demaille <akim@epita.fr>
4427
4428 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
4429 not yyvalue.
4430
4431 2002-11-12 Akim Demaille <akim@epita.fr>
4432
4433 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
4434 Use it to test the GLR parser.
4435
4436 2002-11-12 Akim Demaille <akim@epita.fr>
4437
4438 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
4439 defines it.
4440 * data/glr.c (yystos): New.
4441 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
4442 (YYDSYMPRINT): New.

4445 * data/yacc.c (yysymprint): Remove, rather...
4446 (b4_yysymprint_generate): invoke.
4447 * data/c.m4 (b4_yysymprint_generate): New.
4448 Accept pointers as arguments, as opposed to the version from
4449 yacc.c.
4450 (b4_yydestruct_generate): Likewise.
4451 * tests/cations.at (Printers and Destructors): Use Bison directives
4452 instead of CPP macros.
4453 Don't rely on internal details.
4454
4455 2002-11-12 Akim Demaille <akim@epita.fr>
4456
4457 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
4458 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
4459 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
4460 it against YYEMPTY and so forth), work on yytoken (i.e., set
4461 it to YYEMPTY etc.).
4462 (yydestruct): Replace with a b4_yydestruct_generate invocation.
4463 (b4_symbol_actions): Remove.
4464 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
4465 for 0, end-of-input.

4468
4469 * doc/bison.texinfo (Destructor Decl): New.

4472
4473 * src/tables.c (tables_generate): Use free for pointers that
4474 cannot be NULL, not XFREE.

4480 the file name.
4481
4482 2002-11-12 Akim Demaille <akim@epita.fr>
4483
4484 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
4485 Restore.
4486 * src/scan-gram.l (last_string): Is global to the file, not to
4487 yylex.
4488 * src/parse-gram.y (input): Don't append the epilogue here,
4489 (epilogue.opt): do it here, and free the scanner's obstack.
4490 * src/reader.c (epilogue_set): Rename as...
4491 (epilogue_augment): this.
4492 * data/c.m4 (b4_epilogue): Defaults to empty.
4493

4510 (symbol_type_set): Adjust.
4511 * src/symtab.c (symbol_new): Takes a struniq.
4512 (symbol_free): Don't free the tag member.

4534 file names.
4535 Don't free the input file name.
4536
4537 2002-11-12 Akim Demaille <akim@epita.fr>
4538
4539 * src/symtab.c (symbol_free): Remove dead deactivated code:

4550 2002-11-11 Paul Eggert <eggert@twinsun.com>
4551
4552 Revamp to fix many (but not all) of the C- and M4-related quoting
4553 problems. Among other things, this fixes the Bison bug reported
4554 by Jan Hubicka when processing the Bash grammar; see:
4555 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
4556
4557 Use new @ escapes consistently. Represent brackets with @{ and @}
4558 rather than @<:@ and @:>@, since this works a bit better with dumb
4559 editors like vi. Represent @ with @@, since @ is now consistently
4560 an escape. Use @oline@ and @ofile@ rather than __oline__ and
4561 __ofile__, to avoid unexpected expansions. Similarly, use @output
4562 rather than #output.
4563
4564 * data/c.m4 (b4_copyright): Omit file name from comment, since
4565 the file name could contain "*/".
4566 (b4_synclines_flag): Don't quote the 2nd argument; it should already
4567 be quoted. All uses changed.
4568
4569 * data/glr.c: Use new @ escapes consistently.
4570 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
4571 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
4572 Remove, since they couldn't handle arbitrary characters in file
4573 names.
4574 * data/lalr1.cc: Likewise.
4575 * data/yacc.c: Likewise.
4576
4577 * src/files.c (output_infix): Remove; all uses removed.
4578 * src/files.h: Likewise.
4579
4580 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
4581 mishandled funny characters in file names, and anyway it isn't
4582 needed any more.
4583 * data/yacc.c: Likewise.
4584 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
4585
4586 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
4587 * data/yacc.c: Likewise.
4588
4589 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
4590 strings now.
4591 (muscle_init): Quote filename as a C string.
4592 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
4593 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
4594 * src/output.c (escaped_file_name_output): New function.
4595 (prepare_symbols): Quote tokens for M4.
4596 (prepare): Don't insert output_infix, output_prefix,
4597 output_parser_name, output_header_name; this is now down by scan-skel.
4598 Insert skeleton as a C string.
4599
4600 * src/output.c (user_actions_output, symbol_destructors_output,
4601 symbol_printers_output): Quote filenames for C and M4.
4602 * src/reader.c (prologue_augment, epilogue_set): Likewise.
4603
4604 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
4605 escapes other than \\ and \'; this simplifies the code.
4606 (<SC_STRING>): Likewise, for \\ and \".
4607 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
4608 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
4609 Use new escapes @{ and @} for [ and ].
4610
4611 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
4612 them with auto vars.
4613 Switch to new escape scheme, where @ is the escape character uniformly.
4614 Abort if a stray escape character is found. Avoid unbounded input
4615 buffer when parsing non-escaped text.
4616
4617 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
4618 __oline__, #output, $@, and @{ do not have unintended meanings.
4619
4620 2002-11-09 Paul Eggert <eggert@twinsun.com>
4621
4622 Fix the test failure due to GCC warnings described in
4623 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
4624 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
4625 evaluate to 0 if it's impossible for NINF to be in the respective
4626 table.
4627 (yygetLRActions, yyrecoverParseError): Use them.
4628
4629 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
4630 counted in the token inserted at end of file. Now takes
4631 location_t *, not location_t, so that the location can be
4632 adjusted. All uses changed.
4633
4634 * tests/regression.at (Invalid inputs): Adjust wording in
4635 diagnostic to match the new behavior.
4636
4637 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
4638 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
4639 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
4640 abort ();'. This reduces the runtime of the "Many lookaheads"
4641 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
4642 GCC 3.2.
4643
4644 2002-11-07 Paul Eggert <eggert@twinsun.com>
4645
4646 * src/parse-gram.y (CHARACTER): Remove unused token.
4647 All uses removed.
4648
4649 * src/scan-gram.l: Remove stack option. We no longer use the
4650 stack, since the stack was never deeper than 1; instead, use the
4651 new auto var c_context to record the stacked value.
4652
4653 Remove nounput option. At an unexpected end of file, we now unput
4654 the minimal input necessary to end cleanly; this simplifies the
4655 code.
4656
4657 Avoid unbounded token sizes where this is easy.
4658
4659 (unexpected_end_of_file): New function.
4660 Use it to systematize the error message on unexpected EOF.
4661 (last-string): Now auto, not static.
4662 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
4663 (scanner_last_string_free): Remove; not used.
4664 (percent_percent_count): Move decl to just before use.
4665 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
4666 not the (never otherwised-used) CHARACTER.
4667
4668 2002-11-07 Akim Demaille <akim@epita.fr>
4669
4670 Let yyerror always receive the msg as last argument, so that
4671 yyerror can be variadic.
4672
4673 * data/yacc.c (b4_yyerror_args): New.
4674 Use it when calling yyerror.
4675 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
4676 Use it when calling yyerror.
4677 * doc/bison.texinfo (Error Reporting): Adjust.
4678 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
4679 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
4680
4681 2002-11-06 Akim Demaille <akim@epita.fr>
4682
4683 #line should have quoted strings.
4684 Ideally, this should be done by m4_quotearg.
4685
4686 * src/scan-skel.l: Include quotearg.h.
4687 Quote __ofile__.
4688 * src/output.c (symbol_printers_output)
4689 (symbol_destructors_output): Quote the file name.
4690
4691 2002-11-06 Akim Demaille <akim@epita.fr>
4692
4693 * tests/regression.at (Invalid inputs): Adjust to the recent
4694 messages.
4695
4696 2002-11-06 Akim Demaille <akim@epita.fr>
4697
4698 Restore --no-lines.
4699 Reported by Jim Kent.
4700
4701 * data/c.m4 (b4_syncline): New.
4702 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
4703 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
4704 * src/output.c (user_actions_output): Likewise.
4705 (prepare): Define 'b4_synclines_flag'.
4706 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
4707
4708 2002-11-06 Akim Demaille <akim@epita.fr>
4709
4710 * src/main.c (main): Free `infile'.
4711 * src/scan-gram.l (handle_syncline): New.
4712 Recognize `#line'.
4713 * src/output.c (user_actions_output, symbol_destructors_output)
4714 (symbol_printers_output): Use the location's file name, not
4715 infile.
4716 * src/reader.c (prologue_augment, epilogue_set): Likewise.
4717
4718 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4719
4720 * src/tables.c (matching_state): Don't allow states to match if
4721 either has GLR conflict entries.
4722
4723 2002-11-05 Paul Eggert <eggert@twinsun.com>
4724
4725 * src/scan-gram.l: Use more accurate diagnostics, e.g.
4726 "integer out of range" rather than "invalid value".
4727 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
4728 accordingly.
4729
4730 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
4731 Also, remove one static variable in the scanner.
4732
4733 * src/scan-gram.l (braces_level): Now auto, not static.
4734 Initialize to zero if the compiler is being picky.
4735 (INITIAL): Clear braces_level instead of incrementing it.
4736 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
4737 as POSIX 1003.1-2001 requires.
4738 * src/system.h (IF_LINT): New macro, taken from coreutils.
4739 * configure.ac: Define "lint" if --enable-gcc-warnings.
4740
4741 2002-11-05 Akim Demaille <akim@epita.fr>
4742
4743 * src/scan-gram.l: When it starts with `%', complain about the
4744 whole directive, not just that `invalid character: %'.
4745
4746 2002-11-04 Akim Demaille <akim@epita.fr>
4747
4748 * Makefile.maint: Update from Autoconf.
4749 (update, cvs-update, po-update, do-po-update): New.
4750
4751 2002-11-04 Akim Demaille <akim@epita.fr>
4752
4753 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
4754 and yyerror.
4755 Have yyerror `use' its arguments.
4756 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
4757 returns true when location & yacc & pure & parse-param.
4758 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
4759
4760 2002-11-04 Akim Demaille <akim@epita.fr>
4761
4762 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
4763 clashes.
4764 * src/scan-gram.l: Use [\'] instead of ['] to pacify
4765 font-lock-mode.
4766 Use complain_at.
4767 Use quote, not quote_n since LOCATION_PRINT no longer uses the
4768 slot 0.
4769
4770 2002-11-03 Paul Eggert <eggert@twinsun.com>
4771
4772 * src/reader.c (get_merge_function, grammar_current_rule_check):
4773 Use consistent diagnostics for reporting type name clashes.
4774 Quote the types with <>, for consistency with Yacc.
4775 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
4776
4777 2002-11-03 Akim Demaille <akim@epita.fr>
4778
4779 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
4780 New.
4781 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
4782 (b4_parse_param): Remove.
4783 Use b4_identification.
4784 Propagate b4_pure_args where needed to pass them to yyerror.
4785 * data/glr.m4 (b4_parse_param): Remove.
4786 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
4787 (b4_lpure_formals): New.
4788 Use b4_identification.
4789 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
4790 b4_user_formals and b4_user_args.
4791 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
4792 (yyreportAmbiguity): When using a pure parser, also need
4793 the location, and the parse-params.
4794 Adjust callers.
4795 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
4796 When using a pure parser, also need the parse-params.
4797 Adjust callers.
4798 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
4799 (%pure-parser + %parse-param) LALR and GLR parsers.
4800 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
4801 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
4802 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
4803 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
4804 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
4805 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
4806 * doc/bison.texinfo: Untabify the whole file.
4807 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
4808 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
4809 (Error Reporting): Adjust to these new directives.
4810 Document %error-verbose, deprecate YYERROR_VERBOSE.
4811
4812 2002-11-03 Akim Demaille <akim@epita.fr>
4813
4814 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
4815 AT_CHECK_CALC_GLR invocations to use % directives, instead of
4816 command line options.
4817 * tests/cxx-type.at: Formatting changes.
4818
4819 2002-11-03 Paul Eggert <eggert@twinsun.com>
4820
4821 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
4822 to count columns correctly, and to check for invalid inputs.
4823
4824 Use mbsnwidth to count columns correctly. Account for tabs, too.
4825 Include mbswidth.h.
4826 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
4827 (extend_location): New function.
4828 (YY_LINES): Remove.
4829
4830 Handle CRLF in C code rather than in Lex code.
4831 (YY_INPUT): New macro.
4832 (no_cr_read): New function.
4833
4834 Scan UCNs, even though we don't fully handle them yet.
4835 (convert_ucn_to_byte): New function.
4836
4837 Handle backslash-newline correctly in C code.
4838 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
4839 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
4840 all uses changed.
4841 (tag, splice): New EREs. Do not allow NUL or newline in tags.
4842 Use {splice} wherever C allows backslash-newline.
4843 YY_STEP after space, newline, vertical-tab.
4844 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
4845
4846 (letter, id): Don't assume ASCII; e.g., spell out a-z.
4847
4848 ({int}, handle_action_dollar, handle_action_at): Check for integer
4849 overflow.
4850
4851 (YY_STEP): Omit trailing semicolon, so that it's more like C.
4852
4853 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
4854 as well as \000. Check for UCHAR_MAX, not 255.
4855 Allow \x with an arbitrary positive number of digits, as in C.
4856 Check for overflow here.
4857 Allow \? and UCNs, for compatibility with C.
4858
4859 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
4860 with quote slot used by complain_at.
4861
4862 * tests/input.at: Add tests for backslash-newline, m4 quotes
4863 in symbols, long literals, and funny escapes in strings.
4864
4865 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
4866 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
4867 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
4868 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
4869 * m4/mbswidth.m4: New file, from GNU coreutils.
4870
4871 * doc/bison.texinfo (Grammar Outline): Document // comments.
4872 (Symbols): Document that trigraphs have no special meaning in Bison,
4873 nor is backslash-newline allowed.
4874 (Actions): Document that trigraphs have no special meaning.
4875
4876 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
4877 no longer used.
4878
4879 2002-11-02 Paul Eggert <eggert@twinsun.com>
4880
4881 * src/reader.c: Don't include quote.h; not needed.
4882 (get_merge_function): Reword warning to be consistent with
4883 type clash diagnostic in grammar_current_rule_check.
4884
4885 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
4886 bug in trigraph handling.
4887
4888 * src/output.c (prepare_symbols): When printing token names,
4889 escape "[" as "@<:@" and likewise for "]".
4890
4891 * src/system.h (errno): Remove declaration, as we are now
4892 assuming C89 or better, and C89 guarantees errno.
4893
4894 2002-10-30 Paul Eggert <eggert@twinsun.com>
4895
4896 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
4897 Check for close failures.
4898 * src/files.h (xfclose): Return void, not int, since it always
4899 returned zero.
4900 * src/files.c (xfclose): Likewise. Report I/O error if ferror
4901 indicates one.
4902 * src/output.c (output_skeleton): Use xfclose rather than fclose
4903 and ferror. xfclose now checks ferror.
4904
4905 * data/glr.c (YYLEFTMOST_STATE): Remove.
4906 (yyreportTree): Use a stack-based leftmost state. This avoids
4907 our continuing battles with bogus warnings about initializers.
4908
4909 2002-10-30 Akim Demaille <akim@epita.fr>
4910
4911 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
4912 #if.
4913
4914 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4915
4916 * tests/glr-regr1.at: New test for reported regressions.
4917 * tests/testsuite.at: Add glr-regr1.at test.
4918 * tests/Makefile.am: Add glr-regr1.at test.
4919
4920 2002-10-24 Paul Eggert <eggert@twinsun.com>
4921
4922 Version 1.75a.
4923
4924 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
4925 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
4926 we use malloc. Don't assume 'A' through 'Z' are contiguous.
4927 Don't assume strdup exists; POSIX says its an XSI extension.
4928 Check for buffer overflow on input.
4929
4930 2002-10-24 Akim Demaille <akim@epita.fr>
4931
4932 * src/output.c (output_skeleton): Don't disable M4sugar comments
4933 too soon: it results in comments being expanded.
4934 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
4935 first output.
4936
4937 2002-10-24 Akim Demaille <akim@epita.fr>
4938
4939 * data/yacc.c (m4_int_type): New.
4940 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
4941 char' as only yacc.c wants K&R portability.
4942 * data/glr.c (yysigned_char): Remove.
4943 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
4944 Reported by Quoc Peyrot.
4945
4946 2002-10-23 Paul Eggert <eggert@twinsun.com>
4947
4948 * src/main.c (main): With --trace=time, report times even if a
4949 non-fatal error occurs. Formerly, the times were reported in some
4950 such cases but not in others.
4951 * src/reader.c (reader): Just return if a complaint has been issued,
4952 instead of exiting, so that 'main' can report times.
4953
4954 2002-10-22 Akim Demaille <akim@epita.fr>
4955
4956 * src/system.h: Include sys/types.
4957 Reported by Bert Deknuydt.
4958
4959 2002-10-23 Paul Eggert <eggert@twinsun.com>
4960
4961 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
4962 Suggested by Art Haas.
4963
4964 2002-10-22 Paul Eggert <eggert@twinsun.com>
4965
4966 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
4967 decl; not needed any more.
4968 * src/main.c (main): Use return to exit, undoing yesterday's change.
4969 The last OS that we could find where this wouldn't work is
4970 SunOS 3.5, and that's too old to worry about now.
4971
4972 * data/glr.c (struct yyltype): Define members even when not
4973 doing locations. This is more consistent with yacc.c, and it
4974 works around the following bug reports:
4975 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
4976 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
4977
4978 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
4979 @acronym consistently. Standardize on "Yacc" instead of "YACC",
4980 "Algol" instead of "ALGOL". Give a bit more history about BNF.
4981
4982 2002-10-22 Akim Demaille <akim@epita.fr>
4983
4984 * data/README: New.
4985
4986 2002-10-21 Paul Eggert <eggert@twinsun.com>
4987
4988 Be consistent about 'bool'; the old code used an enum in one
4989 module and an int in another, and this violates the C standard.
4990 * m4/stdbool.m4: New file, from coreutils 4.5.3.
4991 * configure.ac (AC_HEADER_STDBOOL): Add.
4992 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
4993 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
4994 * src/symtab.c (hash_compare_symbol_t): Likewise.
4995 * src/system.h (bool, false, true): Use a definition consistent
4996 with ../lib/hash.c. All uses changed.
4997
4998 * src/complain.c (warning_issued): Renamed from warn_message_count,
4999 so that we needn't worry about integer overflow (!).
5000 Now of type bool. All uses changed.
5001 (complaint_issued): Renamed from complain_message_count; likewise.
5002
5003 * src/main.c (main): Use exit to exit with failure.
5004

5012 "Try `bison --help'".
5013
5014 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
5015 What was that "2" for?
5016

5018 * src/getargs.c (usage): Likewise.
5019
5020 * src/getargs.c (getargs): When there are too few operands, report
5021 the last one. When there are too many, report the first extra
5022 one. This is how diffutils does it.

5025
5026 Remove K&R vestiges.
5027 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

5031 fatal): Assume prototypes.
5032 * src/complain.h: Assume prototypes.
5033 * src/system.h (PARAMS): Remove.
5034 Include <limits.h> unconditionally, since it's guaranteeed even
5035 for a freestanding C89 compiler.
5036 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
5037 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

5052 arguments and output `void'.
5053 (b4_c_function): Rename as...
5054 (b4_c_function_def): this.
5055 (b4_c_function_decl, b4_c_ansi_function_def)
5056 (b4_c_ansi_function_decl): New.
5057 Change the interpretation of the arguments: before `int, foo', now
5058 `int foo, foo'.
5059 * data/yacc.c (yyparse): Prototype and define thanks to these.
5060 Adjust b4_c_function_def uses.
5061 * data/glr.c (yyparse): Likewise, but ANSI only.

5064
5065 * src/output.c (prepare): Move the definition of `tokens_number',

5098 2002-10-19 Paul Eggert <eggert@twinsun.com>
5099
5100 Do not create a temporary file, as that involves security and
5101 cleanup headaches. Instead, use a pair of pipes.
5102 Derived from a suggestion by Florian Krohm.
5103 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
5104 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
5105 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
5106 (BISON_PREREQ_SUBPIPE): Add.
5107 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

5114 (output_skeleton): Use pipe rather than temporary file for m4 input.
5115 Check that m4sugar.m4 is readable, to avoid deadlock.
5116 Check for pipe I/O error.
5117 * src/scan-skel.l (readpipe): Remove decl.
5118 (scan_skel): New function, to be used in place of m4_invoke.
5119 Read from stream rather than file.
5120
5121 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
5122 float, as this generates a warning on Solaris 8 + GCC 3.2 with
5123 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
5124 this generates a more-accurate value anyway.
5125
5126 * lib/timevar.c (timervar_accumulate): Rename locals to
5127 avoid confusion with similarly-named more-global.
5128 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
5129

5134
5135 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
5136 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
5137 Use them to have `calc.y' ready for %pure-parser.
5138 * data/yacc.c (YYLEX): Pass a yylex return type to
5139 b4_c_function_call.
5140
5141 2002-10-19 Akim Demaille <akim@epita.fr>
5142
5143 Prototype support of %lex-param and %parse-param.
5144
5145 * src/parse-gram.y: Add the definition of the %lex-param and
5146 %parse-param tokens, plus their rules.
5147 Drop the `_' version of %glr-parser.
5148 Add the "," token.
5149 * src/scan-gram.l (INITIAL): Scan them.
5150 * src/muscle_tab.c: Comment changes.
5151 (muscle_insert, muscle_find): Rename `pair' as `probe'.

5156 MUSCLE_INSERT_STRING.
5157 Initialize the obstack earlier.
5158 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
5159 (muscle_pair_list_grow): New.
5160 * data/c.m4 (b4_c_function_call, b4_c_args): New.
5161 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
5162 * tests/calc.at: Use %locations, not --locations.
5163 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
5164
5165 2002-10-19 Akim Demaille <akim@epita.fr>
5166
5167 * src/getargs.c (usage): Take status as argument and exit
5168 accordingly.
5169 Report the traditional `Try ... --help' message when status != 0.
5170 (usage, version): Don't take a FILE * as arg, it is pointless.
5171 (getargs): When there is an incorrect number of arguments, make it
5172 an error, and report it GNUlically thanks to `usage ()'.
5173
5174 2002-10-18 Paul Eggert <eggert@twinsun.com>
5175
5176 * data/glr.c (yyreportParseError): Don't assume that sprintf
5177 yields the length of the printed string, as this is not true
5178 on SunOS 4.1.4. Reported by Peter Klein.
5179
5180 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
5181 * tests/conflicts.at (%nonassoc and eof): Likewise.
5182 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
5183
5184 2002-10-17 Akim Demaille <akim@epita.fr>
5185

5187 * src/getargs.c (trace_types, trace_args): Adjust.
5188 * src/reader.c (grammar_current_rule_prec_set)
5189 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
5190 Standardize error messages.
5191 And s/@prec/%prec/!
5192 (reader): Use trace_flag to enable scanner/parser debugging,
5193 instead of an adhoc scheme.
5194 * src/scan-gram.l: Remove trailing debugging code.
5195
5196 2002-10-16 Paul Eggert <eggert@twinsun.com>
5197
5198 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
5199 MUSCLE_TAB_H.
5200
5201 * NEWS: Officially drop support for building Bison with K&R C,
5202 since it didn't work anyway and it's not worth worrying about.
5203 * Makefile.maint (wget_files): Remove ansi2knr.c.
5204 (ansi2knr.c-url_prefix): Remove.
5205 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

5208
5209 2002-10-15 Paul Eggert <eggert@twinsun.com>
5210
5211 Stop using the "enum_" trick for K&R-style function definitions;
5212 it confused me, and I was the author! Instead, assume that people
5213 who want to use K&R C compilers (when using these modules in GCC,
5214 perhaps?) will run ansi2knr.
5215
5216 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
5217 All uses of "enum_" changed to "enum ".
5218 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

5220

5229 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
5230 Use function prototypes; this removes the need for declaring
5231 static functions simply to provide their prototypes.
5232 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

5294
5295 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
5296 member.

5306 tests/cxx-type.at, tests/headers.at, tests/input.at,
5307 tests/regression.at, tests/synclines.at, tests/torture.at:
5308 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
5309 so that the tests still work even if POSIXLY_CORRECT is set.
5310 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
5311
5312 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
5313 for portability to K&R hosts. Fix typo: signed char is guaranteed
5314 only to 127, not to 128.
5315 * data/glr.c (yysigned_char): New type.
5316 * data/yacc.c (yysigned_char): Likewise.
5317 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
5318
5319 2002-10-13 Paul Eggert <eggert@twinsun.com>
5320
5321 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
5322 true due to limited range of data type" warning from GCC.
5323
5324 * data/c.m4 (b4_token_defines): Protect against double-inclusion
5325 by wrapping enum yytokentype's definition inside #ifndef
5326 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
5327
5328 2002-10-13 Akim Demaille <akim@epita.fr>
5329
5330 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
5331 Un yy- yyrhs to avoid the name clash with the global YYRHS.
5332
5333 2002-10-13 Akim Demaille <akim@epita.fr>
5334
5335 * Makefile.maint: Update from Autoconf 2.54.

5344 2002-10-13 Akim Demaille <akim@epita.fr>
5345
5346 Let nondeterministic skeletons be usable with deterministic
5347 tables.
5348
5349 With the patch, GAWK compiled by GCC without -O2 passes its test
5350 suite using a GLR parser driven by LALR tables. It fails with -O2
5351 because `struct stat' gives two different answers on my machine:
5352 88 (definition of an auto var) and later 96 (memset on this var).
5353 Hence the stack is badly corrumpted. The headers inclusion is to
5354 blame: if I move the awk.h inclusion before GLR's system header
5355 inclusion, the two struct stat have the same size.
5356
5357 * src/tables.c (pack_table): Always create conflict_table.
5358 (token_actions): Always create conflict_list.
5359 * data/glr.c (YYFLAG): Remove, unused.
5360
5361 2002-10-13 Akim Demaille <akim@epita.fr>

5371
5372 2002-10-13 Akim Demaille <akim@epita.fr>
5373
5374 * data/glr.c: Formatting changes.
5375 Tweak some trace messages to match yacc.c's.
5376
5377 2002-10-13 Akim Demaille <akim@epita.fr>
5378
5379 GLR parsers sometimes raise parse errors instead of performing the
5380 default reduction.
5381 Reported by Charles-Henry de Boysson.
5382
5383 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
5384 check the length of the traces when %glr.
5385 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
5386 GLR's traces.
5387 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
5388 Test GLR parsers.
5389 * data/glr.c (YYLEFTMOST_STATE): Fix its value.

5392 (yygetLRActions): Map error action number from YYTABLE from
5393 YYTABLE_NINF to 0.
5394 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
5395 (which was a bug: it should have been YYTABEL_NINF, and yet it was
5396 not satisfying as we could compare an YYACTION computed from
5397 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
5398 only value for error actions.
5399 (yyreportParseError): In verbose parse error messages, don't issue
5400 `error' in the list of expected tokens.
5401 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
5402 next action to perform to match glr.c's decoding.
5403 (yytable): Complete its comment.
5404

5406
5407 Fix problem reported by Henrik Grubbstroem in
5408 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
5409 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
5410 because the Bison parser reads the second action before reducing
5411 the first one.
5412 * src/scan-gram.l (rule_length): New static var.
5413 Use it to keep track of the rule length in the scanner, since
5414 we can't expect the parser to be in lock-step sync with the scanner.
5415 (handle_action_dollar, handle_action_at): Use this var.
5416 * tests/actions.at (Exotic Dollars): Test for the problem.
5417
5418 2002-10-12 Paul Eggert <eggert@twinsun.com>
5419
5420 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
5421 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
5422 Include <sys/time.h> when checking for clock_t and struct tms.
5423 Use same include order as source.
5424 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
5425 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
5426
5427 * lib/timevar.c: Update copyright date and clarify comments.
5428 (get_time) [IN_GCC]: Keep the GCC version for reference.
5429
5430 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
5431 GCC version as of today, then merge Bison's changes.
5432 Change "GCC" to "Bison" in copyright notice. timevar.def's
5433 author is Akim, so change that too.
5434
5435 * src/reader.c (grammar_current_rule_check):
5436 Don't worry about the default action if $$ is untyped.
5437 Prevents bogus warnings reported by Jim Gifford in
5438 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
5439
5440 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
5441 * data/glr.c, data/lalr1.cc, data/yacc.c:
5442 Output token definitions before the first part of user declarations.
5443 Fixes compatibility problem reported by Jim Gifford for kbd in
5444 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
5445
5446 2002-10-11 Paul Eggert <eggert@twinsun.com>
5447
5448 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
5449 (yyparse): here. This undoes some of the 2002-07-25 change.
5450 Compatibility problem reported by Ralf S. Engelschall with
5451 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
5452
5453 2002-10-11 Akim Demaille <akim@epita.fr>
5454
5455 * tests/regression.at Characters Escapes): New.
5456 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
5457 characters.
5458 Reported by Jan Nieuwenhuizen.
5459
5460 2002-10-11 Akim Demaille <akim@epita.fr>

5463
5464 2002-10-10 Paul Eggert <eggert@twinsun.com>
5465
5466 Portability fixes for bitsets; this also avoids several GCC
5467 warnings.
5468
5469 * lib/abitset.c: Include <stddef.h>, for offsetof.
5470 * lib/lbitset.c: Likewise.
5471
5472 * lib/abitset.c (abitset_bytes): Return a size that is aligned
5473 properly for vectors of objects. Do not assume that adding a
5474 header size to a multiple of a word size yields a value that is
5475 properly aligned for the whole union.
5476 * lib/bitsetv.c (bitsetv_alloc): Likewise.
5477
5478 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
5479 unique names for structures.
5480 * lib/ebitset.c (ebitset_bytes): Likewise.
5481 * lib/lbitset.c (lbitset_bytes): Likewise.
5482
5483 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
5484 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
5485 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
5486 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
5487 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
5488 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
5489 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
5490 to improve the type-checking that GCC can do.
5491 * lib/bitset.c (bitset_op4_cmp): Likewise.
5492 * lib/bitset_stats.c (bitset_stats_count,
5493 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
5494 bitset_stats_copy, bitset_stats_disjoint_p,
5495 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
5496 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
5497 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
5498 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
5499 bitset_stats_and_or_cmp, bitset_stats_andn_or,
5500 bitset_stats_andn_or_cmp, bitset_stats_or_and,
5501 bitset_stats_or_and_cmp): Likewise.
5502 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
5503 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
5504 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
5505 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
5506
5507 * lib/abitset.h: Include bitset.h, not bbitset.h.
5508 * lib/ebitset.h: Likewise.
5509 * lib/lbitset.h: Likewise.
5510
5511 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
5512 All instances of parameters of type enum bitset_opts are now of
5513 type enum_bitset_opts, to conform to the C Standard, and similarly
5514 for enum_bitset_type.
5515 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
5516 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
5517
5518 Do not use "struct bitset_struct" to mean different things in
5519 different modules. Not only is this confusing, it violates
5520 the C Standard, which requires that structure types in different
5521 modules must be compatible if one is to be passed to the other.
5522 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
5523 All instances of "struct bitset_struct *" replaced with "bitset".
5524 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
5525 (union bitset_union, struct abitset_struct, struct ebitset_struct,
5526 struct lbitset_struct, struct bitset_stats_struct): New types.
5527 All uses of struct bitset_struct changed to union bitset_union,
5528 etc.
5529 * lib/abitset.c (struct abitset_struct, abitset,
5530 struct bitset_struct): Remove.
5531 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
5532 struct bitset_struct): Remove.
5533 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
5534 bitset_struct): Remove.
5535 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
5536 Likewise.
5537
5538 Do not call a function of type T using a call that assumes the
5539 function is of a different type U. Standard C requires that a
5540 function must be called with a type that is compatible with its
5541 definition.
5542 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
5543 New decls.
5544 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
5545 New functions.
5546 * lib/ebitset.c (PFV): Remove.
5547 * lib/lbitset.c (PFV): Likewise.
5548 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
5549 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
5550 decls.
5551 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
5552 (ebitset_vtable): Use them.
5553 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
5554 lbitset_xor): New functions.
5555 (lbitset_vtable): Use them.
5556
5557 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
5558 Declare.
5559
5560 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
5561 GCC warning.
5562 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
5563 Use offsetof, for simplicity.
5564
5565 2002-10-06 Paul Eggert <eggert@twinsun.com>
5566
5567 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
5568 the same width as int. This reapplies a hunk of the 2002-08-12 patch
5569 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
5570 which was inadvertently undone by the 2002-09-30 patch.
5571 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
5572 the same width as int.
5573
5574 2002-10-04 Paul Eggert <eggert@twinsun.com>
5575
5576 Version 1.50.
5577
5578 * configure.ac (AC_INIT), NEWS: Increment version number.
5579
5580 * doc/bison.texinfo: Minor spelling, grammar, and white space
5581 fixes.
5582 (Symbols): Mention that any negative value returned from yylex
5583 signifies end-of-input. Warn about negative chars. Mention
5584 the portable Standard C character set.
5585
5586 The GNU coding standard says CFLAGS and YFLAGS are reserved
5587 for the installer to set.
5588 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
5589 * src/Makefile.am (AM_CFLAGS): Likewise.
5590 (AM_YFLAGS): Renamed from YFLAGS.
5591
5592 Fix some MAX and MIN problems.
5593 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
5594 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
5595 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
5596 * src/reader.c (reader): Use it.
5597
5598 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
5599 POSIX 1003.1-2001 has removed fgrep.
5600
5601 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
5602
5603 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
5604 interpreted as signed.
5605 * lib/ebitset.c (ebitset_list): Fix bug.
5606
5607 2002-10-01 Paul Eggert <eggert@twinsun.com>
5608
5609 More fixes for 64-bit hosts and large bitsets.
5610
5611 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
5612 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
5613 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
5614 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
5615 struct bitset_vtable.list, struct bitset_vtable.list_reverse,
5616 bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,

5632 Likewise.
5633
5634 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
5635 Use size_t, not unsigned int, to count bytes.
5636 * lib/abitset.h (abitset_bytes): Likewise.
5637 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
5638 Likewise.
5639 * lib/bitset.h (bitset_bytes): Likewise.
5640 * lib/bitset_stats.c (bitset_stats_bytes, bitset_stats_init): Likewise.
5641 * lib/bitset_stats.h (bitset_stats_bytes): Likewise.
5642 * lib/bitsetv.c (bitsetv_alloc): Likewise.

5652 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
5653 abitset_or_and, abitset_or_and_cmp):
5654 Use bitset_windex instead of unsigned int.
5655 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
5656 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
5657 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,
5658 ebitset_elt_find, ebitset_list_reverse, ebitset_list, ebitset_init):
5659 Likewise.
5660 * lib/lbitset.c (lbitset_ones, lbitset_not): Likewise.

5670 * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
5671 BITSET_SIZE_MAX): New macros.
5672 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
5673 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
5674 to BITSET_WINDEX_MAX.
5675
5676 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
5677 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
5678 since we now return the bitset_bindex type (not int).
5679
5680 * lib/bitsetv.c (bitsetv_alloc): Check for arithmetic overflow

5777
5778 * doc/bison.texinfo (Conditions): Make explicit that the GPL
5779 exception applies only to yacc.c. This is a modification of a
5780 patch originally suggested by Akim Demaille.
5781
5782 2002-09-06 Akim Demaille <akim@epita.fr>
5783
5784 * data/c.m4 (b4_copyright): Move the GPL exception comment from
5785 here to...
5786 * data/yacc.c: here.
5787
5788 * data/lalr1.cc (struct yyltype): Don't define it, since we use
5789 LocationType.
5790 (b4_ltype): Default to yy::Location from location.hh.
5791
5792 2002-09-04 Jim Meyering <jim@meyering.net>
5793

5798
5799 * configure.in: Rename as...

5806 * src/lalr.c, src/LR0.c, src/relation.c, src/tables.c: Don't
5807 translate maintainer only messages.

5827 (yyreportParseError): Use size_t for yysize.
5828 (yy_yypstack): No longer nested inside yypstates, as nested
5829 functions are not portable. Do not assume size_t is the
5830 same width as int.
5831 (yypstates): Do not assume that ptrdiff_t is the same width
5832 as int, and similarly for yyposn and YYINDEX.
5833
5834 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
5835
5836 * lib/Makefile.am (INCLUDES): Do not include from the intl
5837 directory, which has been removed.
5838 * src/Makefile.am (INCLUDES): Likewise.

5871 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
5872
5873 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
5874 PROTOTYPES to check for prototypes, and "defined __STDC__" to
5875 check for void *.
5876
5877 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
5878 size_t; the old version tried to do this but casted improperly.
5879 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
5880 (bitset_test): Now returns int, not unsigned long.
5881
5882 * lib/bitset_stats.c: Include "gettext.h".
5883 (_): New macro.
5884 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
5885 name locals "index", as it generates unnecessary warnings on some
5886 hosts that have an "index" function.
5887
5888 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
5889 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

5910 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
5911 lib/timevar.c.
5912 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
5913 manual recommends.
5914 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
5915
5916 * src/complain.c (strerror_r): Remove decl; not needed.
5917 (strerror): Use same pattern as ../lib/error.c.
5918
5919 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
5920
5921 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
5922
5923 * src/main.c (main): Cast result of bindtextdomain and textdomain
5924 to void, to avoid a GCC warning when --disable-nls is in effect.
5925
5926 * src/scan-gram.l: Use strings rather than escapes when possible,
5927 to minimize the number of warnings from xgettext.
5928 (handle_action_dollar, handle_action_at): Don't use isdigit,
5929 as it mishandles negative chars and it may not work as expected
5930 outside the C locale.
5931
5932 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
5933 this is a GCC extension and is not portable to other compilers.
5934
5935 * src/system.h (alloca): Use same pattern as ../lib/error.c.
5936 Do not include <ctype.h>; no longer needed.
5937 Do not include <malloc.h>; no longer needed (and generates
5938 warnings on OpenBSD 3.0).
5939
5940 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
5941 it's not portable.
5942
5943 * tests/regression.at: Do not use 'cc -c input.c -o input';
5944 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
5945
5946 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
5947 exit status as failure, not just exit status 1. Sun C exits
5948 with status 2 sometimes.
5949
5950 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
5951 Use it for the two large tests.
5952
5953 2002-08-02 Akim Demaille <akim@epita.fr>
5954
5955 * src/conflicts.c (conflicts_output): Don't output rules never
5956 reduced here, since anyway that computation doesn't work.
5957 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
5958 (rule_useless_p, rule_never_reduced_p): New.
5959 (grammar_rules_partial_print): Use a filter instead of a range.
5960 Display the title only if needed.

5963 * src/tables.c (action_row): Move the computation of rules never
5964 reduced to...
5965 (token_actions): here.
5966 * src/main.c (main): Make the parser before making the report, so
5967 that rules never reduced are computed.
5968 Call grammar_rules_never_reduced_report.
5969 * src/print.c (print_results): Report rules never reduced.
5970 * tests/conflicts.at, tests/reduce.at: Adjust.
5971
5972 2002-08-01 Akim Demaille <akim@epita.fr>
5973
5974 Instead of attaching lookaheads and duplicating the rules being
5975 reduced by a state, attach the lookaheads to the reductions.
5976
5977 * src/state.h (state_t): Remove the `lookaheads',
5978 `lookaheads_rule' member.
5979 (reductions_t): Add a `lookaheads' member.
5980 Use a regular array for the `rules'.

5982 to 0.

5991 (initialize_LA): this.
5992 (lalr_free): Adjust.
5993 * src/main.c (main): Don't free nullable and derives too early: it
5994 is used by --verbose.
5995 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
5996
5997 2002-08-01 Akim Demaille <akim@epita.fr>

6003 Adjust all dependencies.
6004 * src/nullable.c (set_nullable, free_nullable): Rename as...
6005 (nullable_compute, nullable_free): these.
6006 (rule_list_t): Store rule_t *, not rule_number_t.
6007 * src/state.c (state_rule_lookaheads_print): Directly compare rule
6008 pointers, instead of their numbers.
6009 * src/main.c (main): Call nullable_free, and derives_free earlier,
6010 as they were lo longer used.
6011
6012 2002-08-01 Akim Demaille <akim@epita.fr>
6013
6014 * lib/timevar.c (get_time): Include children time.
6015 * src/lalr.h (LA, LArule): Don't export them: used with the
6016 state_t.
6017 * src/lalr.c (LA, LArule): Static.

6020 * src/tables.c (pack_vector): Check whether loc is >= to the
6021 table_size, not >.
6022 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
6023 (tables_generate): do it, since that's also it which allocates
6024 them.
6025 Don't free LA and LArule, main does.
6026
6027 2002-07-31 Akim Demaille <akim@epita.fr>

6063 * src/getargs.h, src/getargs.c: Support trace_time for
6064 --trace=time.
6065 * src/main.c (stage): Remove.
6066 (main): Replace `stage' invocations with timevar calls.
6067 * src/output.c: Insert pertinent timevar calls.
6068
6069 2002-07-31 Akim Demaille <akim@epita.fr>
6070

6072
6073 * src/getargs.h (enum trace_e): New.
6074 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
6075 (long_options, short_options): --trace/-T takes an optional
6076 argument.
6077 Change all the uses of trace_flag to reflect the new flags.
6078 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.

6090
6091 In verbose parse error message, don't report `error' as an
6092 expected token.
6093 * tests/actions.at (Printers and Destructors): Adjust.
6094 * tests/calc.at (Calculator $1): Adjust.
6095 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
6096 error message, do not report the parser accepts the error token in
6097 that state.
6098
6099 2002-07-30 Akim Demaille <akim@epita.fr>

6112 by conflicts.
6113
6114 * src/LR0.c (save_reductions): Don't make the final state too
6115 different: save its reduction (accept) instead of having a state
6116 without any action (no shift or goto, no reduce).
6117 Note: the final state is now a ``regular'' state, i.e., the
6118 parsers now contain `reduce 0' as default reduction.
6119 Nevertheless, since they decide to `accept' when yystate =
6120 final_state, they still will not reduce rule 0.
6121 * src/print.c (print_actions, print_reduction): Adjust.
6122 * src/output.c (action_row): Track reduced rules.
6123 (token_actions): Report rules never reduced.

6136
6137 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not

6148
6149 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
6150 (endtoken, accept): these.
6151 * src/reader.c (reader): Set endtoken's default tag to "$end".
6152 Set undeftoken's tag to "$undefined" instead of "$undefined.".
6153 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
6154 Adjust.
6155
6156 2002-07-29 Akim Demaille <akim@epita.fr>
6157
6158 * src/reduce.c (reduce_grammar): When the language is empty,
6159 complain about the start symbol, not the axiom.
6160 Use its location.
6161 * tests/reduce.at (Empty Language): New.
6162
6163 2002-07-26 Akim Demaille <akim@epita.fr>
6164
6165 * src/reader.h, src/reader.c (gram_error): ... can't get
6166 yycontrol without making too strong assumptions on the parser
6167 itself.
6168 * src/output.c (prepare_tokens): Use the real 0th value of
6169 token_translations instead of `0'.
6170 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
6171 visible here.
6172 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
6173 for the time being: %locations ought to provide it to yyerror.
6174
6175 2002-07-25 Akim Demaille <akim@epita.fr>
6176
6177 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
6178 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
6179 * tests/regression.at (Web2c Actions): Adjust.
6180
6181 2002-07-25 Akim Demaille <akim@epita.fr>

6186 * src/nullable.c, src/output.c, src/print.c, src/reader.c
6187 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
6188 Iterate from 0 to nrules.
6189 Use rule_number_as_item_number and item_number_as_rule_number.
6190 Adjust to `derive' now containing possibly 0.
6191 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
6192 Handle the `- 1' part in rule numbers from/to item numbers.
6193 * src/conflicts.c (log_resolution): Fix the message which reversed
6194 shift and reduce.
6195 * src/output.c (action_row): Initialize default_rule to -1.

6210

7322 assigning twice the same user number to a token, so that we can
7323 use it in...
7324 * src/lex.c (lex): here.
7325 Also use `symbol_class_set' instead of hand written code.
7326 * src/reader.c (parse_assoc_decl): Likewise.

7335
7336 2002-06-10 Akim Demaille <akim@epita.fr>
7337
7338 Remove `%thong' support as it is undocumented, unused, duplicates
7339 `%token's job, and creates useless e-mail traffic with people who
7340 want to know what it is, why it is undocumented, unused, and
7341 duplicates `%token's job.
7342
7343 * src/reader.c (parse_thong_decl): Remove.

7409
7410 2002-05-27 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
7411
7412 * src/output.c (output_skeleton): Put an explicit path in front of
7413 the skeleton file name, rather than relying on the -I directory,
7414 to partially alleviate effects of having a skeleton file lying around

7418
7419 * src/conflicts.c (log_resolution): Correct typo:

7486 and Paul Eggert <eggert@twinsun.com>
7487
7488 * data/bison.simple (yyparse): Correct error handling to conform to

7496
7497 * data/bison.simple (yyr1): Don't use yy_token_number_type as element

7501 the latter can be removed.

7714 Adjust callers.
7715 (copy_at, copy_dollar): Instead of outputting the hard coded
7716 values of $$, $n and so forth, output invocation to b4_lhs_value,
7717 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
7718 Note: this patch partially drops `semantic-parser' support: it
7719 always does `rule_length - n', where semantic parsers ought to
7720 always use `-n'.

7825 2002-04-22 Akim Demaille <akim@epita.fr>
7826
7827 * src/reader.c (token_translations_init): 256 is now the default
7828 value for the error token, i.e., it will be assigned another
7829 number if the user assigned 256 to one of her tokens.
7830 (reader): Don't force 256 to error.
7831 * doc/bison.texinfo (Symbols): Adjust.
7832 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
7833 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
7834 etc. instead of 10, 20, 30 (which was used to `jump' over error

7836
7837 2002-04-22 Akim Demaille <akim@epita.fr>
7838

7871
7872 2002-04-09 Akim Demaille <akim@epita.fr>
7873
7874 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
7875 full stderr, and strip it according to the bison options, instead
7876 of composing the error message from different bits.
7877 This makes it easier to check for several error messages.
7878 Adjust all the invocations.
7879 Add an invocation exercising the error token.
7880 Add an invocation demonstrating a stupid error message.
7881 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

7892 * src/symtab.h: here.
7893 (state_t.number): Is a token_number_t.
7894 * src/print.c, src/reader.c: Use undeftoken->number instead of
7895 hard coded 2.
7896 (Even though this 2 is not the same as above: the number of the
7897 undeftoken remains being 2, it is its user token number which
7898 might not be 2).
7899 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
7900 `user_token_number_max'.
7901 Output `undef_token_number'.
7902 * data/bison.simple, data/bison.c++: Use them.
7903 Be sure to map invalid yylex return values to
7904 `undef_token_number'. This saves us from gratuitous SEGV.

7921
7922 * src/gram.h (item_number_t): New, the type of item numbers in
7923 RITEM. Note that it must be able to code symbol numbers as
7924 positive number, and the negation of rule numbers as negative
7925 numbers.
7926 Adjust all dependencies (pretty many).
7927 * src/reduce.c (rule): Remove this `short *' pointer: use
7928 item_number_t.
7929 * src/system.h (MINSHORT, MAXSHORT): Remove.
7930 Include `limits.h'.
7931 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

7937 * tests/torture.at (Big triangle): Move the limit from 254 to
7938 500.
7939 * tests/regression.at (Web2c Actions): Ajust.
7940
7941 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
7942 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
7943 passes, but produces negative #line number, once fixed, GCC is
7944 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
7945 C), it passes.
7946 * src/state.h (state_h): Code input lines on ints, not shorts.
7947
7948 2002-04-08 Akim Demaille <akim@epita.fr>

7963 New.
7964 Use them to define yy_token_number_type/TokenNumberType.
7965 Use this type for yytranslate.
7966 * tests/torture.at (Big triangle): Push the limit from 124 to
7967 253.

8416 translator friendly scheme for the bgr
8417 copyright notice.
8418
8419 2002-02-25 Akim Demaille <akim@epita.fr>
8420
8421 * src/output.c (header_output): Remove, now handled completely via
8422 M4.
8423
8424 2002-02-25 Akim Demaille <akim@epita.fr>
8425
8426 * m4/m4.m4: New, from CVS Autoconf.
8427 * configure.in: Invoke it.
8428 * src/output.c (output_skeleton): Use its result instead of the
8429 hard coded name.
8430
8431 2002-02-25 Akim Demaille <akim@epita.fr>
8432
8433 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
8434 Fileutils 4.1.5.
8435 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
8436 * src/output.c (output_skeleton): Use mkstemp to create a real
8437 temporary file.
8438 Move the filling of `skeleton' and its muscle to...
8439 (prepare): here.
8440 (output): Move the definition of the prologue muscle to...
8441 (prepare): here.
8442 * src/system.h (DEFAULT_TMPDIR): New.
8443
8444 2002-02-14 Paul Eggert <eggert@twinsun.com>
8445
8446 Remove the support for C++ namespace cleanliness; it was
8447 causing more problems than it was curing, since it didn't work
8448 properly on some nonstandard C++ compilers. This can wait
8449 for a proper C++ parser.
8450
8451 * NEWS: Document this.
8452 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
8453 of C++, as it's treated like C now.
8454 * src/bison.simple (YYSTD): Remove.
8455 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
8456 Treat C++ just like Standard C instead of trying to support
8457 namespace cleanliness.
8458
8459 2002-02-14 Akim Demaille <akim@epita.fr>
8460
8461 * tests/regression.at (else): Adjust to Andreas' change.
8462
8463 2002-02-14 Akim Demaille <akim@epita.fr>
8464
8465 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
8466
8467 2002-02-13 Andreas Schwab <schwab@suse.de>
8468
8469 * src/output.c (output_rule_data): Don't output NULL, it might
8470 not be defined yet.
8471
8472 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
8473
8474 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
8475 (Copyright notice): Update.
8476
8477 2002-02-11 Akim Demaille <akim@epita.fr>
8478
8479 * tests/regression.at (%nonassoc and eof): Don't include
8480 nonportable headers.
8481
8482 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
8483
8484 * data/bison.c++: Correct error recovery. Make the user able to
8485 initialize the starting location.
8486
8487 2002-02-07 Akim Demaille <akim@epita.fr>
8488
8489 * tests/input.at: New.
8490
8491 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
8492
8493 * data/bison.c++: Replace some direct m4 expansions by constants. Be
8494 more consistent when naming methods and variables. Put preprocessor
8495 directives around tables only needed for debugging.
8496
8497 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
8498
8499 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
8500 C++ parsers.
8501 (yy::b4_name::parse): Use print_.
8502
8503 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
8504
8505 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
8506
8507 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
8508
8509 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
8510 C++ parsers.
8511 (yy::b4_name::parse): Build verbose error messages, and use error_.
8512
8513 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
8514
8515 * data/bison.c++: Fix m4 quoting in comments.
8516
8517 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
8518
8519 * data/bison.c++: Adjust the parser code. Fix some muscles that were
8520 not expanded by m4.
8521
8522 2002-02-05 Akim Demaille <akim@epita.fr>
8523
8524 * data/bison.c++: Adjust to the M4 back end.
8525 More is certainly needed.
8526
8527 2002-02-05 Akim Demaille <akim@epita.fr>
8528
8529 Give a try to M4 as a back end.
8530
8531 * lib/readpipe.c: New, from wdiff.
8532 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
8533 BISON_HAIRY.
8534 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
8535 specific values. Now it is m4 that performs the lookup.
8536 * src/parse-skel.y: Remove.
8537 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
8538 * src/output.c (actions_output, guards_output)
8539 (token_definitions_output): No longer keeps track of the output
8540 line number, hence remove the second argument.
8541 (guards_output): Check against the guard member of a rule, not the
8542 action member.
8543 Adjust callers.
8544 (output_skeleton): Don't look for the skeleton location, let m4 do
8545 that.
8546 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
8547 file will be used.
8548 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
8549 (prepare): Given that for the time being changesyntax is not
8550 usable in M4, rename the muscles using `-' to `_'.
8551 Define `defines_flag', `output_parser_name' and `output_header_name'.
8552 * src/output.h (actions_output, guards_output)
8553 (token_definitions_output): Adjust prototypes.
8554 * src/scan-skel.l: Instead of scanning the skeletons, it now
8555 processes the output of m4: `__oline__' and `#output'.
8556 * data/bison.simple: Adjust to be used by M4(sugar).
8557 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
8558 to date.
8559 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
8560 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
8561 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
8562 shamelessly stolen from CVS Autoconf.
8563
8564 2002-02-05 Akim Demaille <akim@epita.fr>
8565
8566 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
8567 * configure.in: Check for the declarations of free and malloc.
8568 * src/muscle_tab.c: Adjust.
8569
8570 2002-02-05 Akim Demaille <akim@epita.fr>
8571
8572 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
8573 which have no values.
8574
8575 2002-02-05 Akim Demaille <akim@epita.fr>
8576
8577 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
8578 * data/: here.
8579
8580 2002-01-29 Paul Eggert <eggert@twinsun.com>
8581
8582 * src/bison.simple (YYSIZE_T): Do not define merely because
8583 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
8584 On some platforms, <alloca.h> does not declare YYSTD (size_t).
8585
8586 2002-01-27 Akim Demaille <akim@epita.fr>
8587
8588 Fix `%nonassoc and eof'.
8589
8590 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
8591 which were not properly copied! Replace
8592 memcpy (res->errs, src->errs, src->nerrs);
8593 with
8594 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
8595 !!!
8596 * tests/regression.at (%nonassoc and eof): Adjust to newest
8597 Autotest: `.' is not in the PATH.
8598
8599 2002-01-27 Akim Demaille <akim@epita.fr>
8600
8601 * tests/sets.at (AT_EXTRACT_SETS): New.
8602 (Nullable): Use it.
8603 (Firsts): New.
8604
8605 2002-01-26 Akim Demaille <akim@epita.fr>
8606
8607 * tests/actions.at, tests/calc.at, tests/headers.at,
8608 * tests/torture.at: Adjust to the newest Autotest which no longer
8609 forces `.' in the PATH.
8610
8611 2002-01-25 Akim Demaille <akim@epita.fr>
8612
8613 * tests/regression.at (%nonassoc and eof): New.
8614 Suggested by Robert Anisko.
8615
8616 2002-01-24 Akim Demaille <akim@epita.fr>
8617
8618 Bison dumps core when trying to complain about broken input files.
8619 Reported by Cris van Pelt.
8620
8621 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
8622 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
8623 into...
8624 (Invalid inputs): Strengthen: exercise parse_percent_token.
8625
8626 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
8627
8628 * src/Makefile.am: Add bison.c++.
8629 * src/bison.c++: New skeleton.
8630
8631 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
8632
8633 * po/it.po: New.
8634
8635 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
8636
8637 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
8638
8639 2002-01-20 Marc Autret <marc@gnu.org>
8640
8641 * src/files.c (compute_output_file_names): Fix
8642
8643 2002-01-20 Marc Autret <marc@gnu.org>
8644
8645 * tests/output.at: New test.
8646 * src/files.c (compute_base_names): Don't map extensions when
8647 the YACC flag is set, use defaults.
8648 Reported by Evgeny Stambulchik.
8649
8650 2002-01-20 Marc Autret <marc@gnu.org>
8651
8652 * src/system.h: Need to define __attribute__ away for non-GCC
8653 compilers as well (i.e. the vendor C compiler).
8654 Suggested by Albert Chin-A-Young.
8655
8656 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
8657
8658 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
8659 canonical definition.
8660 * src/system.h: Use the canonical definition for PARAMS (avoids
8661 a conflict with the macro from lib/hash.h).
8662
8663 2002-01-11 Akim Demaille <akim@epita.fr>
8664
8665 * configure.in: Use AC_FUNC_STRNLEN.
8666 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
8667
8668 2002-01-09 Akim Demaille <akim@epita.fr>
8669
8670 * src/files.c, src/files.h (output_infix): New.
8671 (tab_extension): Remove.
8672 (compute_base_names): Compute the former, drop the latter.
8673 * src/output.c (prepare): Insert the muscles `output-infix', and
8674 `output-suffix'.
8675 * src/parse-skel.y (string, string.1): New.
8676 (section.header): Use it.
8677 (section.yacc): Remove.
8678 (prefix): Remove too.
8679 * src/scan-skel.l: Adjust.
8680 * src/bison.simple, src/bison.hairy: Adjust.
8681
8682 2002-01-09 Akim Demaille <akim@epita.fr>
8683
8684 * configure.in (WERROR_CFLAGS): Compute it.
8685 * src/Makefile.am (CFLAGS): Pass it.
8686 * tests/atlocal.in (CFLAGS): Idem.
8687 * src/files.c: Fix a few warnings.
8688 (get_extension_index): Remove, unused.
8689
8690 2002-01-08 Akim Demaille <akim@epita.fr>
8691
8692 * src/getargs.c (AS_FILE_NAME): New.
8693 (getargs): Use it to convert DOSish file names.
8694 * src/files.c (base_name): Rename as full_base_name to avoid
8695 clashes with `base_name ()'.
8696 (filename_split): New.
8697 (compute_base_names): N-th rewrite, using filename_split.
8698
8699 2002-01-08 Akim Demaille <akim@epita.fr>
8700
8701 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
8702 New, stolen from the Fileutils 4.1.
8703 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
8704 * configure.in: Check for the presence of memrchr, and of its
8705 prototype.
8706
8707 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
8708
8709 * lib/hash.h (__P): Added definition for this macro.
8710 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
8711 BUILT_SOURCES, to ensure they are generated first.
8712 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
8713 %error-verbose to allow bootstrapping with bison 1.30x.
8714
8715 2002-01-06 Akim Demaille <akim@epita.fr>
8716
8717 * src/reader.c (parse_braces): Don't fetch the next char, the
8718 convention is to fetch on entry.
8719 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
8720 'switch' without a following semicolon.
8721 * tests/regression.at (braces parsing): New.
8722
8723 2002-01-06 Akim Demaille <akim@epita.fr>
8724
8725 Bison is dead wrong in its RR conflict reports.
8726
8727 * tests/torture.at (GNU Cim Grammar): New.
8728 * src/conflicts.c (count_rr_conflicts): Fix.
8729
8730 2002-01-06 Akim Demaille <akim@epita.fr>
8731
8732 Creating package.m4 from configure.ac causes too many problems.
8733
8734 * tests/Makefile.am (package.m4): Create it by hand,
8735 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
8736
8737 2002-01-06 Akim Demaille <akim@epita.fr>
8738
8739 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
8740 skeleton.h.
8741
8742 2002-01-04 Paul Eggert <eggert@twinsun.com>
8743
8744 * doc/bison.texinfo (Debugging):
8745 Remove YYSTDERR; it's no longer defined or used.
8746 Also, s/cstdio.h/cstdio/.
8747
8748 2002-01-03 Akim Demaille <akim@epita.fr>
8749
8750 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
8751
8752 2002-01-03 Akim Demaille <akim@epita.fr>
8753
8754 * src/parse-skel.y (process_skeleton): Don't bind the parser's
8755 tracing code to --trace, wait for a better --trace option, with
8756 args.
8757
8758 2002-01-03 Akim Demaille <akim@epita.fr>
8759
8760 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
8761 The ISO C++ standard is extremely clear about it: stderr is
8762 considered a macro, not a regular symbol (see table 94 `Header
8763 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
8764 Therefore std:: does not apply to it. It still does with fprintf.
8765 Also, s/cstdio.h/cstdio/.
8766
8767 2002-01-03 Akim Demaille <akim@epita.fr>
8768
8769 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
8770 for non system headers.
8771
8772 2002-01-02 Akim Demaille <akim@epita.fr>
8773
8774 Equip the skeleton chain with location tracking, runtime trace,
8775 pure parser and scanner.
8776
8777 * src/parse-skel.y: Request a pure parser, locations, and prefix
8778 renaming.
8779 (%union): Having several members with the same type does not help
8780 type mismatches, simplify.
8781 (YYPRINT, yyprint): New.
8782 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
8783 (skel_error): this.
8784 Handle locations.
8785 * src/scan-skel.l: Adjust to these changes.
8786 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
8787 (LOCATION_PRINT, skel_control_t): New.
8788
8789 2001-12-30 Akim Demaille <akim@epita.fr>
8790
8791 * src/parse-skel.y: Get rid of the shift/reduce conflict:
8792 replace `gb' with BLANKS.
8793 * src/scan-skel.l: Adjust.
8794
8795 2001-12-30 Akim Demaille <akim@epita.fr>
8796
8797 * src/system.h: We don't need nor want bcopy.
8798 Throw away MS-DOS crap: we don't need getpid.
8799 * configure.in: We don't need strndup. It was even causing
8800 problems: because Flex includes the headers *before* us,
8801 _GNU_SOURCE is not defined by config.h, and therefore strndup was
8802 not visible.
8803 * lib/xstrndup.c: New.
8804 * src/scan-skel.l: Use it.
8805 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
8806 * src/parse-skel.y: Use %directives instead of #defines.
8807
8808 2001-12-30 Akim Demaille <akim@epita.fr>
8809
8810 * src/skeleton.h: New.
8811 * src/output.c (output_parser, output_master_parser): Remove, dead
8812 code.
8813 * src/output.h (get_lines_number, actions_output, guards_output)
8814 (token_definitions_output): Prototype them.
8815 * src/parse-skel.y: Add the license notice.
8816 Include output.h and skeleton.h.
8817 (process_skeleton): Returns void, and takes a single parameter.
8818 * src/scan-skel.l: Add the license notice.
8819 Include skeleton.h.
8820 Don't use %option yylineno: it seems that then Flex imagines
8821 REJECT has been used, and therefore it won't reallocate its
8822 buffers (which makes no other sense to me than a bug). It results
8823 in warnings for `unused: yy_flex_realloc'.
8824
8825 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
8826
8827 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
8828 (MUSCLE_INSERT_PREFIX): ...to there.
8829 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
8830 (MUSCLE_INSERT_PREFIX): Move from here...
8831
8832 * src/bison.hairy: Add a section directive. Put braces around muscle
8833 names. This parser skeleton is still broken, but Bison should not
8834 choke on a bad muscle 'syntax'.
8835 * src/bison.simple: Add a section directive. Put braces around muscle
8836 names.
8837
8838 * src/files.h (strsuffix, stringappend): Add declarations.
8839 (tab_extension): Add declaration.
8840 (short_base_name): Add declaration.
8841
8842 * src/files.c (strsuffix, stringappend): No longer static. These
8843 functions are used in the skeleton parser.
8844 (tab_extension): New.
8845 (compute_base_names): Use the computations done in this function
8846 to guess if the generated parsers should have '.tab' in their
8847 names.
8848 (short_base_name): No longer static.
8849
8850 * src/output.c (output_skeleton): New.
8851 (output): Disable call to output_master_parser, and give a try to
8852 a new skeleton handling system.
8853 (guards_output, actions_output): No longer static.
8854 (token_definitions_output, get_lines_number): No longer static.
8855
8856 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
8857
8858 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
8859 parse-skel.y.
8860
8861 * src/parse-skel.y: New file.
8862 * src/scan-skel.l: New file.
8863
8864 2001-12-29 Akim Demaille <akim@epita.fr>
8865
8866 %name-prefix is broken.
8867
8868 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
8869 Adjust all dependencies.
8870 * tests/headers.at (export YYLTYPE): Strengthen this test: use
8871 %name-prefix.
8872
8873 Renaming yylval but not yylloc is not consistent. Now we do.
8874
8875 * src/bison.simple: Prefix yylloc if used.
8876 * doc/bison.texinfo (Decl Summary): Document that.
8877
8878 2001-12-29 Akim Demaille <akim@epita.fr>
8879
8880 * doc/bison.texinfo: Promote `%long-directive' over
8881 `%long_directive'.
8882 Remove all references to fixed-output-files, yacc is enough.
8883
8884 2001-12-29 Akim Demaille <akim@epita.fr>
8885
8886 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
8887 user prologue. These are defaults.
8888 * tests/actions.at (Mid-rule actions): Make sure the user can
8889 define YYDEBUG and YYERROR_VERBOSE.
8890
8891 2001-12-29 Akim Demaille <akim@epita.fr>
8892
8893 * src/output.c (header_output): Don't forget to export YYLTYPE and
8894 yylloc.
8895 * tests/headers.at (export YYLTYPE): New, make sure it does.
8896 * tests/regression.at (%union and --defines, Invalid CPP headers):
8897 Move to...
8898 * tests/headers.at: here.
8899
8900 2001-12-29 Akim Demaille <akim@epita.fr>
8901
8902 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
8903
8904 2001-12-29 Akim Demaille <akim@epita.fr>
8905
8906 * tests/actions.at (Mid-rule actions): Output on a single line
8907 instead of several.
8908
8909 2001-12-29 Akim Demaille <akim@epita.fr>
8910
8911 * doc/bison.texinfo: Formatting changes.
8912
8913 2001-12-29 Akim Demaille <akim@epita.fr>
8914
8915 Don't store the token defs in a muscle, just be ready to output it
8916 on command. Now possible via `symbols'. Fixes a memory leak.
8917
8918 * src/output.c (token_definitions_output): New.
8919 (output_parser, header_output): Use it.
8920 * src/reader.c (symbols_save): Remove.
8921
8922 2001-12-29 Akim Demaille <akim@epita.fr>
8923
8924 * src/bison.simple: Do not provide a default for YYSTYPE and
8925 YYLTYPE before the user's prologue. Otherwise it's hardly... a
8926 default.
8927
8928 2001-12-29 Akim Demaille <akim@epita.fr>
8929
8930 Mid-rule actions are simply... ignored!
8931
8932 * src/reader.c (readgram): Be sure to attach mid-rule actions to
8933 the empty-rule associated to the dummy symbol, not to the host
8934 rule.
8935 * tests/actions.at (Mid-rule actions): New.
8936
8937 2001-12-29 Akim Demaille <akim@epita.fr>
8938
8939 Memory leak.
8940
8941 * src/reader.c (reader): Free grammar.
8942
8943 2001-12-29 Akim Demaille <akim@epita.fr>
8944
8945 Memory leak.
8946
8947 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
8948 since it allocates it for each state, although only one is needed.
8949 (allocate_storage): Do it here.
8950
8951 2001-12-29 Akim Demaille <akim@epita.fr>
8952
8953 * src/options.h, src/options.c (create_long_option_table): Rename
8954 as...
8955 (long_option_table_new): this, with a clearer prototype.
8956 (percent_table): Remove, unused,
8957 * src/getargs.c (getargs): Adjust.
8958
8959 2001-12-29 Akim Demaille <akim@epita.fr>
8960
8961 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
8962 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
8963 as states.
8964
8965 2001-12-29 Akim Demaille <akim@epita.fr>
8966
8967 * src/lalr.c (build_relations): Rename `states' as `states1'.
8968 Sorry, I don't understand exactly what it is, no better name...
8969
8970 2001-12-29 Akim Demaille <akim@epita.fr>
8971
8972 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
8973 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
8974 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
8975 as rules.
8976
8977 2001-12-29 Akim Demaille <akim@epita.fr>
8978
8979 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
8980 ago.
8981
8982 2001-12-29 Akim Demaille <akim@epita.fr>
8983
8984 * src/reader.c, src/reader.h (user_toknums): Remove.
8985 Adjust all users to use symbols[i]->user_token_number.
8986
8987 2001-12-29 Akim Demaille <akim@epita.fr>
8988
8989 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
8990 Adjust all users to use symbols[i]->prec or ->assoc.
8991
8992 2001-12-29 Akim Demaille <akim@epita.fr>
8993
8994 * src/reader.c, src/reader.h (tags): Remove.
8995 Adjust all users to use symbols[i]->tag.
8996
8997 2001-12-29 Akim Demaille <akim@epita.fr>
8998
8999 * src/gram.h, src/gram.c (symbols): New, similar to state_table
9000 and rule_table.
9001 * src/reader.c (packsymbols): Fill this table.
9002 Drop sprec.
9003 * src/conflicts.c (resolve_sr_conflict): Adjust.
9004 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
9005 single table.
9006 Use symbols[i]->tag instead of tags[i].
9007
9008 2001-12-29 Akim Demaille <akim@epita.fr>
9009
9010 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
9011 In addition, put a comment in there, to replace...
9012 * tests/regression.at (%union and C comments): Remove.
9013
9014 2001-12-29 Akim Demaille <akim@epita.fr>
9015
9016 * tests/regression.at (Web2c Actions): Blindly move the actual
9017 output as expected output. The contents *seem* right to me, but I
9018 can't pretend reading perfectly parser tables... Nonetheless, all
9019 the other tests pass correctly, the table look OK, even though the
9020 presence of `$axiom' is to be noted: AFAICS it is useless (but
9021 harmless).
9022
9023 2001-12-29 Akim Demaille <akim@epita.fr>
9024
9025 * src/reader.c (readgram): Don't add the rule 0 if there were no
9026 rules read. In other words, add it _after_ having performed
9027 grammar sanity checks.
9028 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
9029
9030 2001-12-29 Akim Demaille <akim@epita.fr>
9031
9032 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
9033 visible, and some states have now a different number.
9034
9035 2001-12-29 Akim Demaille <akim@epita.fr>
9036
9037 * src/reader.c (readgram): Bind the initial rule's lineno to that
9038 of the first rule.
9039 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
9040 (Solved SR Conflicts): Adjust rule 0's line number.
9041
9042 2001-12-29 Akim Demaille <akim@epita.fr>
9043
9044 Fix the `GAWK Grammar' failure.
9045
9046 * src/LR0.c (final_state): Initialize to -1 so that we do compute
9047 the reductions of the first state which was mistakenly confused
9048 with the final state because precisely final_state was initialized
9049 to 0.
9050 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
9051 now noticed by Bison.
9052 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
9053 have a reduction on $default.
9054
9055 2001-12-29 Akim Demaille <akim@epita.fr>
9056
9057 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
9058 rule line numbers.
9059 * src/closure.c (print_closure): Likewise.
9060 * src/derives.c (print_derives): Likewise.
9061 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
9062 now.
9063
9064 2001-12-29 Akim Demaille <akim@epita.fr>
9065
9066 * src/lalr.c (lookaheads_print): New.
9067 (lalr): Call it when --trace-flag.
9068 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
9069 are dumped.
9070
9071 2001-12-29 Akim Demaille <akim@epita.fr>
9072
9073 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
9074 when walking through ritem, even via rule->rhs.
9075 * src/reduce.c (dump_grammar, useful_production, reduce_output)
9076 (useful_production, useless_nonterminals): Likewise.
9077 (reduce_grammar_tables): Likewise, plus update nritems.
9078 * src/nullable.c (set_nullable): Likewise.
9079 * src/lalr.c (build_relations): Likewise.
9080 * tests/sets.at (Nullable): Adjust.
9081 Fortunately, now, the $axiom is no longer nullable.
9082
9083 2001-12-29 Akim Demaille <akim@epita.fr>
9084
9085 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
9086 the 0-sentinel.
9087 * src/gram.c (ritem_longest_rhs): Likewise.
9088 * src/reduce.c (nonterminals_reduce): Likewise.
9089 * src/print_graph.c (print_graph): Likewise.
9090 * src/output.c (output_rule_data): Likewise.
9091 * src/nullable.c (set_nullable): Likewise.
9092
9093 2001-12-29 Akim Demaille <akim@epita.fr>
9094
9095 * src/output.c: Comment changes.
9096
9097 2001-12-27 Paul Eggert <eggert@twinsun.com>
9098
9099 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
9100 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
9101 Sparc, as they were causing more porting problems than the
9102 (minor) performance improvement was worth.
9103
9104 Also, catch up with 1.31's YYSTD.
9105
9106 2001-12-27 Akim Demaille <akim@epita.fr>
9107
9108 * src/output.c (output_gram): Rely on nritems, not the
9109 0-sentinel. See below.
9110 Use -1 as separator, not 0.
9111 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
9112 Rely on -1 as separator in yyrhs, instead of 0.
9113 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
9114 twice `Now at end of input', therefore there are two lines less to
9115 expect.
9116
9117 2001-12-27 Akim Demaille <akim@epita.fr>
9118
9119 * tests/regression.at (Unresolved SR Conflicts):
9120 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
9121 below.
9122
9123 2001-12-27 Akim Demaille <akim@epita.fr>
9124
9125 * src/LR0.c (new_state): Recognize the final state by the fact it
9126 is reached by eoftoken.
9127 (insert_start_shifting_state, insert_eof_shifting_state)
9128 (insert_accepting_state, augment_automaton): Remove, since now
9129 these states are automatically computed from the initial state.
9130 (generate_states): Adjust.
9131 * src/print.c: When reporting a rule number to the user, substract
9132 1, so that the axiom rule is rule 0, and the first user rule is 1.
9133 * src/reduce.c: Likewise.
9134 * src/print_graph.c (print_core): For the time being, just as for
9135 the report, depend upon --trace-flags to dump the full set of
9136 items.
9137 * src/reader.c (readgram): Once the grammar read, insert the rule
9138 0: `$axiom: START-SYMBOL $'.
9139 * tests/set.at: Adjust: rule 0 is now displayed, and since the
9140 number of the states has changed (the final state is no longer
9141 necessarily the last), catch up.
9142
9143 2001-12-27 Akim Demaille <akim@epita.fr>
9144
9145 Try to make the use of the eoftoken valid. Given that its value
9146 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
9147 is used instead of > 0 where appropriate, (ii), depend upon nritems
9148 instead of the 0-sentinel.
9149
9150 * src/gram.h, src/gram.c (nritems): New.
9151 Expected to be duplication of nitems, but for the time being...
9152 * src/reader.c (packgram): Assert nritems and nitems are equal.
9153 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
9154 * src/closure.c (print_closure, print_fderives): Likewise.
9155 * src/gram.c (ritem_print): Likewise.
9156 * src/print.c (print_core, print_grammar): Likewise.
9157 * src/print_graph.c: Likewise.
9158
9159 2001-12-27 Akim Demaille <akim@epita.fr>
9160
9161 * src/main.c (main): If there are complains after grammar
9162 reductions, then output the report anyway if requested, then die.
9163 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
9164 * src/reader.c (eoftoken): New.
9165 (parse_token_decl): If the token being defined has value `0', it
9166 is the eoftoken.
9167 (packsymbols): No longer hack `tags' to insert `$' by hand.
9168 Be sure to preserve the value of the eoftoken.
9169 (reader): Make sure eoftoken is defined.
9170 Initialize nsyms to 0: now eoftoken is created just like the others.
9171 * src/print.c (print_grammar): Don't special case the eof token.
9172 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
9173 lie anyway, albeit pleasant.
9174 * tests/calc.at: Exercise error messages with eoftoken.
9175 Change the grammar so that empty input is invalid.
9176 Adjust expectations.
9177 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
9178
9179 2001-12-27 Akim Demaille <akim@epita.fr>
9180
9181 * configure.in: Check the protos of strchr ans strspn.
9182 Replace strchr if needed.
9183 * src/system.h: Provide the protos of strchr, strspn and memchr if
9184 missing.
9185 * lib/strchr.c: New.
9186 * src/reader.c (symbols_save): Use strchr.
9187
9188 2001-12-27 Akim Demaille <akim@epita.fr>
9189
9190 * src/print.c, src/print_graph.c (escape): New.
9191 Use it to quote the TAGS outputs.
9192 * src/print_graph.c (print_state): Now errors are in red, and
9193 reductions in green.
9194 Prefer high to wide: output the state number on a line of its own.
9195
9196 2001-12-27 Akim Demaille <akim@epita.fr>
9197
9198 * src/state.h, src/state.c (reductions_new): New.
9199 * src/LR0.c (set_state_table): Let all the states have a
9200 `reductions', even if reduced to 0.
9201 (save_reductions): Adjust.
9202 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
9203 * src/print.c (print_reductions, print_actions): Adjust.
9204 * src/output.c (action_row): Adjust.
9205
9206 2001-12-27 Akim Demaille <akim@epita.fr>
9207
9208 * src/state.h, src/state.c (errs_new, errs_dup): New.
9209 * src/LR0.c (set_state_table): Let all the states have an errs,
9210 even if reduced to 0.
9211 * src/print.c (print_errs, print_reductions): Adjust.
9212 * src/output.c (output_actions, action_row): Adjust.
9213 * src/conflicts.c (resolve_sr_conflict): Adjust.
9214
9215 2001-12-27 Akim Demaille <akim@epita.fr>
9216
9217 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
9218
9219 2001-12-27 Akim Demaille <akim@epita.fr>
9220
9221 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
9222 * src/print.c: here.
9223 (lookaheadset, shiftset): New, used as additional storage by
9224 print_reductions.
9225 (print_results): Adjust.
9226 (print_shifts, print_gotos, print_errs): New, extracted from...
9227 (print_actions): here.
9228 * src/print_graph.c (print_actions): Remove dead code.
9229
9230 2001-12-27 Akim Demaille <akim@epita.fr>
9231
9232 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
9233 `$n' and `@n'.
9234
9235 2001-12-27 Akim Demaille <akim@epita.fr>
9236
9237 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
9238 (build_relations): Adjust.
9239
9240 2001-12-27 Akim Demaille <akim@epita.fr>
9241
9242 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
9243 duplication.
9244
9245 2001-12-27 Akim Demaille <akim@epita.fr>
9246
9247 * src/reader.c (packgram): Catch nitems overflows.
9248
9249 2001-12-27 Akim Demaille <akim@epita.fr>
9250
9251 * src/files.c, src/files.h (guard_obstack): Remove.
9252 * src/output.c (output): Adjust.
9253 * src/reader.c (parse_braces): New, factoring...
9254 (copy_action, copy_guard): these two which are renamed as...
9255 (parse_action, parse_guard): these.
9256 As a voluntary consequence, using braces around guards is now
9257 mandatory.
9258
9259 2001-12-27 Akim Demaille <akim@epita.fr>
9260
9261 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
9262 * src/reader.c (symbol_list): `guard' and `guard_line' are new
9263 members.
9264 (symbol_list_new): Adjust.
9265 (copy_action): action_line is the first line, not the last.
9266 (copy_guard): Just as for actions, store the `action' only, not
9267 the switch/case/break flesh.
9268 Don't parse the user action that might follow the guard, let...
9269 (readgram): do it, i.e., now, there can be an action after a
9270 guard.
9271 In other words the guard is just explicitly optional.
9272 (packgram): Adjust.
9273 * src/output.c (guards_output): New.
9274 (output_parser): Call it when needed.
9275 (output): Also free the guard and attrs obstacks.
9276 * src/files.c, src/files.h (obstack_save): Remove.
9277 (output_files): Remove.
9278 As a result, if one needs the former `.act' file, using an
9279 appropriate skeleton which requires actions and guards is now
9280 required.
9281 * src/main.c (main): Adjust.
9282 * tests/semantic.at: New.
9283 * tests/regression.at: Use `input.y' as input file name.
9284 Avoid 8+3 problems by requiring input.c when the test needs the
9285 parser.
9286
9287 2001-12-27 Akim Demaille <akim@epita.fr>
9288
9289 * src/reader.c (symbol_list_new): Be sure to initialize all the
9290 fields.
9291
9292 2001-12-27 Akim Demaille <akim@epita.fr>
9293
9294 All the hacks using a final pseudo state are now useless.
9295
9296 * src/LR0.c (set_state_table): state_table holds exactly nstates.
9297 * src/lalr.c (nLA): New.
9298 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
9299 instead of lookaheadsp from the pseudo state (nstate + 1).
9300
9301 2001-12-27 Akim Demaille <akim@epita.fr>
9302
9303 * src/output.c (action_row, token_actions): Use a state_t instead
9304 of a integer, and nlookaheads instead of the following state's
9305 lookaheadsp.
9306
9307 2001-12-27 Akim Demaille <akim@epita.fr>
9308
9309 * src/conflicts.c (log_resolution, flush_shift)
9310 (resolve_sr_conflict, set_conflicts, solve_conflicts)
9311 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
9312 (conflicts_print, print_reductions): Use a state_t instead of an
9313 integer when referring to a state.
9314 As much as possible, depend upon nlookaheads, instead of the
9315 `lookaheadsp' member of the following state (since lookaheads of
9316 successive states are successive, the difference between state n + 1
9317 and n served as the number of lookaheads for state n).
9318 * src/lalr.c (add_lookback_edge): Likewise.
9319 * src/print.c (print_core, print_actions, print_state)
9320 (print_results): Likewise.
9321 * src/print_graph.c (print_core, print_actions, print_state)
9322 (print_graph): Likewise.
9323 * src/conflicts.h: Adjust.
9324
9325 2001-12-27 Akim Demaille <akim@epita.fr>
9326
9327 * src/bison.hairy: Formatting/comment changes.
9328 ANSIfy.
9329 Remove `register' indications.
9330 Add plenty of `static'.
9331
9332 2001-12-27 Akim Demaille <akim@epita.fr>
9333
9334 * src/output.c (prepare): Drop the muscle `ntbase' which
9335 duplicates ntokens.
9336 * src/bison.simple: Formatting/comment changes.
9337 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
9338 is an undocumented synonym.
9339
9340 2001-12-22 Akim Demaille <akim@epita.fr>
9341
9342 * src/output.c (output_table_data): Change the prototype to use
9343 `int' for array ranges: some invocations do pass an int, not a
9344 short.
9345 Reported by Wayne Green.
9346
9347 2001-12-22 Akim Demaille <akim@epita.fr>
9348
9349 Some actions of web2c.y are improperly triggered.
9350 Reported by Mike Castle.
9351
9352 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
9353 * tests/regression.at (Web2c): Rename as...
9354 (Web2c Report): this.
9355 (Web2c Actions): New.
9356
9357 2001-12-22 Akim Demaille <akim@epita.fr>
9358
9359 Reductions in web2c.y are improperly reported.
9360 Reported by Mike Castle.
9361
9362 * src/conflicts.c (print_reductions): Fix.
9363 * tests/regression.at (Web2c): New.
9364
9365 2001-12-18 Akim Demaille <akim@epita.fr>
9366
9367 Some host fail on `assert (!"foo")', which expands to
9368 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
9369 Reported by Nelson Beebee.
9370
9371 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
9372 `#define it_succeeded 0' and `assert (it_succeeded)'.
9373
9374 2001-12-17 Marc Autret <autret_m@epita.fr>
9375
9376 * src/bison.simple: Don't hard code the skeleton line and filename.
9377 * src/output.c (output_parser): Rename 'line' as 'output_line'.
9378 New line counter 'skeleton_line' (skeleton-line muscle).
9379
9380 2001-12-17 Paul Eggert <eggert@twinsun.com>
9381
9382 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
9383 YYDEBUG must be defined to a nonzero value.
9384
9385 * src/bison.simple (yytname): Do not assume that the user defines
9386 YYDEBUG to a properly parenthesized expression.
9387
9388 2001-12-17 Akim Demaille <akim@epita.fr>
9389
9390 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
9391 nlookaheads is a new member.
9392 Adjust all users.
9393 * src/lalr.h (nlookaheads): Remove this orphan declaration.
9394 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
9395 state.
9396
9397 2001-12-17 Akim Demaille <akim@epita.fr>
9398
9399 * src/files.h, src/files.c (open_files, close_files): Remove.
9400 * src/main.c (main): Don't open/close files, nor invoke lex_free,
9401 let...
9402 * src/reader.c (reader): Do it.
9403
9404 2001-12-17 Akim Demaille <akim@epita.fr>
9405
9406 * src/conflicts.c (print_reductions): Formatting changes.
9407
9408 2001-12-17 Akim Demaille <akim@epita.fr>
9409
9410 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
9411 (flush_reduce): New.
9412 (resolve_sr_conflict): Adjust.
9413
9414 2001-12-17 Akim Demaille <akim@epita.fr>
9415
9416 * src/output.c (output_obstack): Be static and rename as...
9417 (format_obstack): this, to avoid any confusion with files.c's
9418 output_obstack.
9419 * src/reader.h (muscle_obstack): Move to...
9420 * src/output.h: here, since it's defined in output.c.
9421
9422 2001-12-17 Akim Demaille <akim@epita.fr>
9423
9424 * src/output.c (action_row, save_column, default_goto)
9425 (sort_actions, matching_state, pack_vector): Better variable
9426 locality.
9427
9428 2001-12-17 Akim Demaille <akim@epita.fr>
9429
9430 * src/output.c: Various formatting changes.
9431
9432 2001-12-17 Akim Demaille <akim@epita.fr>
9433
9434 * src/files.c (output_files): Free the output_obstack.
9435 * src/main.c (main): Call print and print_graph conditionally.
9436 * src/print.c (print): Work unconditionally.
9437 * src/print_graph.c (print_graph): Work unconditionally.
9438 * src/conflicts.c (log_resolution): Output only if verbose_flag.
9439
9440 2001-12-16 Marc Autret <autret_m@epita.fr>
9441
9442 * src/output.c (actions_output): Fix. When we use %no-lines,
9443 there is one less line per action.
9444
9445 2001-12-16 Marc Autret <autret_m@epita.fr>
9446
9447 * src/bison.simple: Remove a useless #line directive.
9448 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
9449 * src/output.c (get_lines_number): New.
9450 (output_parser): Adjust, now takes care about the lines of a
9451 output muscles.
9452 Fix line numbering.
9453 (actions_output): Computes the number of lines taken by actions.
9454 (output_master_parser): Insert new skeleton which is the name of
9455 the output parser file name.
9456
9457 2001-12-15 Marc Autret <autret_m@epita.fr>
9458
9459 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
9460
9461 2001-12-15 Marc Autret <autret_m@epita.fr>
9462
9463 * src/output.c (output_gram): Keep track of the hairy one.
9464
9465 2001-12-15 Akim Demaille <akim@epita.fr>
9466
9467 Make `make distcheck' work.
9468
9469 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
9470 system.h which uses libgettext.h.
9471
9472 2001-12-15 Akim Demaille <akim@epita.fr>
9473
9474 * src/nullable.c (set_nullable): Useless rules must be skipped,
9475 otherwise, since we range over their symbols, we might look at a
9476 nonterminal which no longer ``exists'', i.e., it is not counted in
9477 `nvars', hence we overflow our arrays.
9478
9479 2001-12-15 Akim Demaille <akim@epita.fr>
9480
9481 The header can also be produced directly, without any obstack!
9482 Yahoo!
9483
9484 * src/files.c, src/files.h (defines_obstack): Remove.
9485 (compute_header_macro): Global.
9486 (defines_obstack_save): Remove.
9487 * src/reader.c (parse_union_decl): No longer output to
9488 defines_obstack: its content can be found in the `stype' muscle
9489 anyway.
9490 (output_token_translations): Merge into...
9491 (symbols_output): this.
9492 Rename as...
9493 (symbols_save): this.
9494 (reader): Adjust.
9495 * src/output.c (header_output): New.
9496 (output): Call it.
9497
9498 2001-12-15 Akim Demaille <akim@epita.fr>
9499
9500 * src/reader.c (parse_union_decl): Instead of handling two obstack
9501 simultaneously, use one to define the `stype' muscle, and use the
9502 value of the latter to fill defines_obstack.
9503 (copy_comment): Remove.
9504 (copy_comment2): Work for a single obstack.
9505 Rename as...
9506 (copy_comment): this.
9507
9508 2001-12-15 Akim Demaille <akim@epita.fr>
9509
9510 * src/lex.c, src/lex.h (xgetc): No longer static.
9511 * src/reader.c (parse_union_decl): Revamp.
9512
9513 2001-12-15 Akim Demaille <akim@epita.fr>
9514
9515 Still making progress in separating Bison into (i) input, (ii)
9516 process, (iii) output: now we can directly output the parser file
9517 without using table_obstack at all.
9518
9519 * src/files.c, src/files.h (table_obstack): Bye bye.
9520 (parser_file_name): New.
9521 * src/files.c (compute_output_file_names): Compute it.
9522 * src/output.c (actions_output, output_parser)
9523 (output_master_parser): To a file instead of an obstack.
9524
9525 2001-12-15 Akim Demaille <akim@epita.fr>
9526
9527 Attach actions to rules, instead of pre-outputting them to
9528 actions_obstack.
9529
9530 * src/gram.h (rule_t): action and action_line are new members.
9531 * src/reader.c (symbol_list): Likewise.
9532 (copy_action): Save the actions within the rule.
9533 (packgram): Save them in rule_table.
9534 * src/output.c (actions_output): New.
9535 (output_parser): Use it on `%%actions'.
9536 (output_rule_data): Don't free rule_table.
9537 (output): Do it.
9538 (prepare): Don't save the `action' muscle.
9539 * src/bison.simple: s/%%action/%%actions/.
9540
9541 2001-12-15 Akim Demaille <akim@epita.fr>
9542
9543 * src/reader.c (copy_action): When --yacc, don't append a `;'
9544 to the user action: let it fail if lacking.
9545 Suggested by Arnold Robbins and Tom Tromey.
9546
9547 2001-12-14 Akim Demaille <akim@epita.fr>
9548
9549 * src/lex.c (literalchar): Simply return the char you decoded, non
9550 longer mess around with obstacks and int pointers.
9551 Adjust all callers.
9552
9553 2001-12-14 Akim Demaille <akim@epita.fr>
9554
9555 * src/lex.c (literalchar): Don't escape the special characters,
9556 just decode them, and keep them as char (before, eol was output as
9557 the 2 char string `\n' etc.).
9558 * src/output.c (output_rule_data): Use quotearg to output the
9559 token strings.
9560
9561 2001-12-13 Paul Eggert <eggert@twinsun.com>
9562
9563 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
9564 Do not infringe on the global user namespace when using C++.
9565 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
9566 All uses of `fprintf' and `stderr' changed.
9567
9568 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
9569
9570 2001-12-13 Akim Demaille <akim@epita.fr>
9571
9572 The computation of nullable is broken: it doesn't handle empty
9573 RHS's properly.
9574
9575 * tests/torture.at (GNU AWK Grammar): New.
9576 * tests/sets.at (Nullable): New.
9577 * src/nullable.c (set_nullable): Instead of blindly looping over
9578 `ritems', loop over the rules, and then over their rhs's.
9579
9580 Work around Autotest bugs.
9581
9582 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
9583 frame, because Autotest understand lines starting with a `+' as
9584 traces from the shell. Then, they are not processed properly.
9585 Admittedly an Autotest bug, but we don't have time to wait for
9586 Autotest to catch up.
9587 * tests/regression.at (Broken Closure): Adjust to the new table
9588 frames.
9589 Move to...
9590 * tests/sets.at: here.
9591
9592 2001-12-13 Akim Demaille <akim@epita.fr>
9593
9594 * src/closure.c (closure): Use nrules instead of playing tricks
9595 with BITS_PER_WORD.
9596
9597 2001-12-13 Akim Demaille <akim@epita.fr>
9598
9599 * src/print.c (print_actions): Output the handling of `$' as the
9600 traces do: shifting the token EOF. Before EOF was treated as a
9601 nonterminal.
9602 * tests/regression.at: Adjust some tests.
9603 * src/print_graph.c (print_core): Complete the set of items via
9604 closure. The next-to-final and final states are still unsatisfying,
9605 but that's to be addressed elsewhere.
9606 No longer output the rule numbers, but do output the state number.
9607 A single loop for the shifts + gotos is enough, but picked a
9608 distinct color for each.
9609 (print_graph): Initialize and finalize closure.
9610
9611 2001-12-13 Akim Demaille <akim@epita.fr>
9612
9613 * src/reader.c (readgram): Remove dead code, an strip useless
9614 braces.
9615 (get_type): Remove, unused.
9616
9617 2001-12-12 Akim Demaille <akim@epita.fr>
9618
9619 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
9620 on that of lib/error.c.
9621
9622 2001-12-12 Akim Demaille <akim@epita.fr>
9623
9624 Some hosts don't like `/' in includes.
9625
9626 * src/system.h: Include libgettext.h without qualifying the path.
9627 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
9628 $(top_srcdir).
9629
9630 2001-12-11 Marc Autret <autret_m@epita.fr>
9631
9632 * src/output.c (output_parser): Remove useless muscle.
9633
9634 2001-12-11 Marc Autret <autret_m@epita.fr>
9635
9636 * src/bison.simple: Remove #line just before %%epilogue. It
9637 is now handled in ...
9638 * src/reader.c (read_additionnal_code): Add the output of a
9639 #line for the epilogue.
9640
9641 2001-12-10 Marc Autret <autret_m@epita.fr>
9642
9643 * src/reader.c (copy_definition): Re-use CPP-outed code which
9644 replace precedent remove.
9645 * src/bison.simple: Remove #line before %%prologue because
9646 %%input-line is wrong at this time.
9647
9648 2001-12-10 Marc Autret <autret_m@epita.fr>
9649
9650 * src/reader.c (symbols_output): Clean up.
9651 * src/output.c (output_gram, output): Clean up.
9652
9653 2001-12-10 Akim Demaille <akim@epita.fr>
9654
9655 * src/lalr.c (initialize_lookaheads): New. Extracted from...
9656 * src/LR0.c (set_state_table): here.
9657 * src/lalr.c (lalr): Call it.
9658
9659 2001-12-10 Akim Demaille <akim@epita.fr>
9660
9661 * src/state.h (shifts): Remove the `number' member: shifts are
9662 attached to state, hence no longer need to be labelled with a
9663 state number.
9664
9665 2001-12-10 Akim Demaille <akim@epita.fr>
9666
9667 Now that states have a complete set of members, the linked list of
9668 shifts is useless: just fill directly the state's shifts member.
9669
9670 * src/state.h (shifts): Remove the `next' member.
9671 * src/LR0.c (first_state, last_state): Remove.
9672 Adjust the callers.
9673 (augment_automaton): Don't look for the shifts that must be added
9674 a shift on EOF: it is those of the state we looked for! But now,
9675 since shifts are attached, it is no longer needed to looking
9676 merely by its id: its number.
9677
9678 2001-12-10 Akim Demaille <akim@epita.fr>
9679
9680 * src/LR0.c (augment_automaton): Better variable locality.
9681 Remove an impossible branch: if there is a state corresponding to
9682 the start symbol being shifted, then there is shift for the start
9683 symbol from the initial state.
9684
9685 2001-12-10 Akim Demaille <akim@epita.fr>
9686
9687 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
9688 only when appropriate: when insert_start_shifting_state' is not
9689 invoked.
9690 * tests/regression.at (Rule Line Numbers): Adjust.
9691
9692 2001-12-10 Akim Demaille <akim@epita.fr>
9693
9694 * src/LR0.c (augment_automaton): Now that all states have shifts,
9695 merge the two cases addition shifts to the initial state.
9696
9697 2001-12-10 Akim Demaille <akim@epita.fr>
9698
9699 * src/lalr.c (set_state_table): Move to...
9700 * src/LR0.c: here.
9701 * src/lalr.c (lalr): Don't call it...
9702 * src/LR0.c (generate_states): do it.
9703 * src/LR0.h (first_state): Remove, only the table is used.
9704
9705 2001-12-10 Akim Demaille <akim@epita.fr>
9706
9707 * src/LR0.h (first_shift, first_reduction): Remove.
9708 * src/lalr.c: Don't use first_shift: find shifts through the
9709 states.
9710
9711 2001-12-10 Akim Demaille <akim@epita.fr>
9712
9713 * src/LR0.c: Attach shifts to states as soon as they are
9714 computed.
9715 * src/lalr.c (set_state_table): Instead of assigning shifts to
9716 state, just assert that the mapping was properly done.
9717
9718 2001-12-10 Akim Demaille <akim@epita.fr>
9719
9720 * src/LR0.c (insert_start_shift): Rename as...
9721 (insert_start_shifting_state): this.
9722 (insert_eof_shifting_state, insert_accepting_state): New.
9723 (augment_automaton): Adjust.
9724 Better locality of the variables.
9725 When looking if the start_symbol is shifted from the initial
9726 state, using `while (... symbol != start_symbol ...)' sounds
9727 better than `while (... symbol < start_symbol ...)': If fail
9728 to see how the order between symbols could be relevant!
9729
9730 2001-12-10 Akim Demaille <akim@epita.fr>
9731
9732 * src/getargs.h: Don't declare `spec_name_prefix' and
9733 `spec_file_prefix', declared by src/files.h.
9734 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
9735 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
9736 * src/output.c (prepare): Adjust.
9737 * src/reader.c (symbols_output): Likewise.
9738 * src/vmsgetargs.c: Vaguely adjust, but who cares?
9739
9740 2001-12-10 Akim Demaille <akim@epita.fr>
9741
9742 * src/muscle_tab.c (muscle_init): NULL is a better default than
9743 `"0"'.
9744
9745 2001-12-10 Akim Demaille <akim@epita.fr>
9746
9747 * src/reader.c (reader): Calling symbols_output once is enough.
9748
9749 2001-12-10 Akim Demaille <akim@epita.fr>
9750
9751 Now that states have a complete set of members, the linked list of
9752 reductions is useless: just fill directly the state's reductions
9753 member.
9754
9755 * src/state.h (struct reductions): Remove member `number' and
9756 `next'.
9757 * src/LR0.c (first_reduction, last_reduction): Remove.
9758 (save_reductions): Don't link the new reductions, store them in
9759 this_state.
9760 * src/lalr.c (set_state_table): No need to attach reductions to
9761 states, it's already done.
9762 * src/output.c (output_actions): No longer free the shifts, then
9763 the reductions, then the states: free all the states and their
9764 members.
9765
9766 2001-12-10 Akim Demaille <akim@epita.fr>
9767
9768 * src/options.c (OPTN, DRTV, BOTH): New.
9769 (option_table): Use them.
9770
9771 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
9772 the job of system.h.
9773 * src/options.c: Don't include stdio.h and xalloc.h for the same
9774 reasons.
9775
9776 2001-12-10 Akim Demaille <akim@epita.fr>
9777

9786 (parse_skel_decl): Be static.
9787 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
9788 * src/options.h (create_long_option_table): Have a real prototype.
9789 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
9790 (hash_delete_at): Return const void *.
9791 Adjust casts to preserve the const.
9792
9793 2001-12-10 Akim Demaille <akim@epita.fr>
9794
9795 * configure.in: Require 2.52g.
9796 M4 is not needed, but AUTOM4TE is.
9797 * m4/m4.m4: Remove.
9798 * tests/Makefile.am: Adjust.
9799
9800 2001-12-10 Akim Demaille <akim@epita.fr>
9801
9802 One structure for states is enough, even though theoretically
9803 there are LR(0) states and LALR(1) states.
9804
9805 * src/lalr.h (state_t): Remove.
9806 (state_table): Be state_t **, not state_t *.
9807 * src/state.h (core, CORE_ALLOC): Rename as...
9808 (state_t, STATE_ALLOC): this.
9809 Add the LALR(1) members: shifts, reductions, errs.
9810 * src/LR0.c (state_table): Rename as...
9811 (state_hash): this, to avoid name clashes with the global
9812 `state_table'.
9813 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
9814 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
9815
9816 2001-12-10 Akim Demaille <akim@epita.fr>
9817
9818 Bison dumps core on bash.y.
9819 Reported by Pascal Bart.
9820
9821 * src/warshall.c (bitmatrix_print): New.
9822 (TC): Use it.
9823 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
9824 j must be the outer loop.
9825 * tests/regression.at (Broken Closure): New.
9826
9827 2001-12-05 Akim Demaille <akim@epita.fr>
9828
9829 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and

9840
9841 2001-12-05 Akim Demaille <akim@epita.fr>
9842
9843 * src/reduce.c (reduce_grammar_tables): No longer disable the
9844 removal of useless rules via CPP but via `if (0)', so that the
9845 compiler still check the code is valid.
9846 For instance, it should have noticed `rline' no longer exists: use
9847 the `line' member of rule_t.
9848 * src/gram.c (dummy, rline): Remove, unused.
9849
9850 2001-12-05 Akim Demaille <akim@epita.fr>
9851
9852 * src/output.c (pack_vector): Use assert, not berror.
9853 * src/main.c (berror): Remove, unused.
9854
9855 2001-12-05 Akim Demaille <akim@epita.fr>
9856
9857 New experimental feature: if --verbose --trace output all the
9858 items of a state, not only its kernel.
9859
9860 * src/print.c (print_core): If `trace_flag', then invoke closure
9861 before outputting the items of the state (print_core is no longer
9862 a correct name them).
9863 (print_results): Invoke new_closure/free_closure if needed.
9864
9865 2001-12-05 Akim Demaille <akim@epita.fr>
9866
9867 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.

9869 (nitemset): for consistency with the rest of the project.
9870
9871 2001-12-05 Akim Demaille <akim@epita.fr>
9872
9873 * src/closure.c (print_closure): Improve.
9874 (closure): Use it for printing input and output.
9875
9876 2001-12-05 Akim Demaille <akim@epita.fr>
9877
9878 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
9879 indexed by nonterminals.
9880
9881 2001-12-05 Akim Demaille <akim@epita.fr>
9882
9883 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
9884 what it was!).
9885 * src/warshall.h: Remove accidental duplication of the content.
9886
9887 2001-12-05 Akim Demaille <akim@epita.fr>
9888

9896
9897 * src/closure.c (set_firsts): De-obfuscate.
9898
9899 2001-12-05 Akim Demaille <akim@epita.fr>
9900
9901 * src/output.c (action_row): De-obfuscate
9902 using the good o' techniques: arrays not pointers, variable
9903 locality, BITISSET, RESETBIT etc.
9904
9905 2001-12-05 Akim Demaille <akim@epita.fr>
9906
9907 Pessimize the code to simplify it: from now on, all the states
9908 have a valid SHIFTS, which NSHIFTS is possibly 0.
9909
9910 * src/LR0.c (shifts_new): Be global and move to..
9911 * src/state.c, src/state.h: here.
9912 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
9913 * src/print_graph: Adjust.
9914
9915 2001-12-05 Akim Demaille <akim@epita.fr>
9916
9917 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
9918 * src/conflicts.c: Use it.
9919 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
9920 incorrectly ``simplified''.
9921
9922 2001-12-05 Akim Demaille <akim@epita.fr>
9923
9924 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

9926 locality, BITISSET, RESETBIT etc.
9927
9928 2001-12-05 Akim Demaille <akim@epita.fr>
9929

9934
9935 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
9936 (print_reductions): De-obfuscate using the good o' techniques:
9937 arrays not pointers, variable locality, BITISSET.
9938
9939 2001-12-05 Akim Demaille <akim@epita.fr>
9940
9941 * src/conflicts.c (print_reductions): Arrays, not pointers.
9942 Use BITISSET.
9943
9944 2001-12-05 Akim Demaille <akim@epita.fr>
9945
9946 * src/conflicts.c (print_reductions): Pessimize, but clarify.
9947
9948 2001-12-05 Akim Demaille <akim@epita.fr>
9949

9955
9956 2001-12-05 Akim Demaille <akim@epita.fr>
9957
9958 * src/conflicts.c (print_reductions): Improve variable locality.
9959
9960 2001-12-05 Akim Demaille <akim@epita.fr>
9961
9962 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
9963 * src/lalr.c: Use them.
9964
9965 2001-12-05 Akim Demaille <akim@epita.fr>
9966
9967 * src/LR0.c (augment_automaton): Formatting changes.
9968 Better variable locality.
9969
9970 2001-12-05 Akim Demaille <akim@epita.fr>
9971
9972 * src/lalr.c (matrix_print): New.
9973 (transpose): Use it.
9974 Use arrays instead of pointers.
9975
9976 2001-12-05 Akim Demaille <akim@epita.fr>
9977
9978 * src/lalr.c (maxrhs): Move to...
9979 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
9980 * src/lalr.c (build_relations): Adjust.
9981
9982 2001-12-05 Akim Demaille <akim@epita.fr>
9983
9984 * src/lalr.c (transpose): Free the memory allocated to the
9985 argument, as it is replaced by the results by the unique caller.
9986 (build_relations): Merely invoke transpose: it handles the memory
9987 deallocation.
9988 Improve variable locality.
9989 Avoid variables used as mere abbreviations.
9990 (compute_lookaheads): Use arrays instead of pointers.
9991
9992 2001-12-05 Akim Demaille <akim@epita.fr>
9993
9994 * src/lalr.c (initialize_F): Improve variable locality.
9995 Avoid variables used as mere abbreviations.

10003
10004 2001-12-05 Akim Demaille <akim@epita.fr>
10005
10006 * src/lalr.c (traverse): Use arrays instead of pointers.
10007
10008 2001-12-05 Akim Demaille <akim@epita.fr>
10009
10010 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
10011 the handling of squeue.
10012 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
10013
10014 2001-12-05 Akim Demaille <akim@epita.fr>
10015
10016 Because useless nonterminals are now kept alive (instead of being
10017 `destroyed'), we now sometimes examine them, and store information
10018 related to them. Hence we need to know their number, and adjust
10019 memory allocations.
10020
10021 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
10022 static.
10023 * src/LR0.c (allocate_itemsets): The memory allocated to
10024 `symbol_count' was used for two different purpose: once to count
10025 the number of occurrences of each symbol, and later reassigned to
10026 `shift_symbol', containing the symbol that can be shifted from a
10027 given state.
10028 Deobfuscate, i.e., allocate, use and free `symbol_count' here
10029 only, and...
10030 (new_itemsets): Allocate `shift_symbol' here.
10031 (allocate_itemsets): symbol_count includes useless nonterminals.
10032 Make room for them.
10033 (free_storage): Use `free', not `XFREE', for pointers that cannot
10034 be null.
10035
10036 2001-12-05 Akim Demaille <akim@epita.fr>
10037
10038 * src/nullable.c (set_nullable): Deobfuscate the handling of
10039 ritem.
10040 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
10041
10042 2001-12-05 Akim Demaille <akim@epita.fr>
10043
10044 * src/gram.c, src/gram.h (ritem_print): New.
10045 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
10046 (This useless function was defined only to work around VMS linkers
10047 that can't handle compilation units with variables only).
10048 * src/reduce.c (dump_grammar): Use it to trace the construction of
10049 ritem.
10050
10051 2001-12-04 Paul Eggert <eggert@twinsun.com>
10052
10053 * src/bison.simple (union yyalloc): Change member names
10054 to be the same as the stack names.
10055 (yyparse): yyptr is now union yyalloc *, not char *.
10056 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
10057 and may generate better code on some machines.
10058 (yystpcpy): Use prototype if __STDC__ is defined, not just
10059 if __cplusplus is defined.
10060
10061 2001-11-30 Akim Demaille <akim@epita.fr>
10062
10063 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
10064 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
10065 Gettext doesn't compile cleanly, and dies with -Werror.
10066 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
10067 Include WARNING_CFLAGS here.
10068 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
10069 before being defined.
10070
10071 2001-11-27 Paul Eggert <eggert@twinsun.com>
10072
10073 * lib/quotearg.h (quotearg_n, quotearg_n_style):
10074 First arg is int, not unsigned.
10075 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
10076 (SIZE_MAX, UINT_MAX): New macros.
10077 (quotearg_n_options): Abort if N is negative.
10078 Avoid overflow check on hosts where size_t is 64 bits and int
10079 is 32 bits, as overflow is impossible there.
10080 Fix off-by-one typo that caused unnecessary reallocation.
10081
10082 2001-11-29 Paul Eggert <eggert@twinsun.com>
10083
10084 Name space cleanup in generated parser.
10085
10086 * doc/bison.texinfo (Bison Parser): Discuss system headers
10087 and their effect on the user name space.
10088
10089 * src/bison.simple:
10090 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
10091 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
10092 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
10093
10094 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
10095 on user names when possible.
10096
10097 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
10098 Simplify test for whather <alloca.h> exists.
10099
10100 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
10101
10102 (<stdio.h>): Include if YYDEBUG.
10103
10104 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
10105 ! defined (yyoverflow) && ! defined (yymemcpy).
10106
10107 (yymemcpy, yyparse): Rename local variables as needed so that
10108 they all begin with 'yy'.
10109
10110 (yystrlen, yystpcpy): New functions.
10111
10112 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
10113 All uses changed.
10114
10115 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
10116 instead of relying on string.h functions. Use YYSTACK_ALLOC
10117 and YYSTACK_FREE instead of malloc and free.
10118
10119 2001-11-30 Akim Demaille <akim@epita.fr>
10120
10121 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
10122 before their first uses.
10123 (YYBISON, YYPURE): Move to the top of the output.
10124
10125 2001-11-30 Akim Demaille <akim@epita.fr>
10126
10127 * tests/reduce.at (Useless Nonterminals): Fix.
10128
10129 2001-11-30 Akim Demaille <akim@epita.fr>
10130
10131 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
10132 if body instead of `;' to pacify GCC's warnings.
10133
10134 2001-11-30 Akim Demaille <akim@epita.fr>
10135
10136 Instead of mapping the LHS of unused rules to -1, keep the LHS
10137 valid, but flag the rules as invalid.
10138
10139 * src/gram.h (rule_t): `useful' is a new member.
10140 * src/print.c (print_grammar): Adjust.
10141 * src/derives.c (set_derives): Likewise.
10142 * src/reader.c (packgram, reduce_output): Likewise.
10143 * src/reduce.c (reduce_grammar_tables): Likewise.
10144 * tests/reduce.at (Underivable Rules, Useless Rules): New.
10145
10146 2001-11-30 Akim Demaille <akim@epita.fr>
10147
10148 * src/reduce.c (reduce_output): Formatting changes.
10149 * src/print.c (print_results, print_grammar): Likewise.
10150 * tests/regression.at (Rule Line Numbers)
10151 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
10152
10153 2001-11-30 Akim Demaille <akim@epita.fr>
10154
10155 * src/reduce.c (nonterminals_reduce): Instead of throwing away
10156 useless nonterminals, move them at the end of the symbol arrays.
10157 (reduce_output): Adjust.
10158 * tests/reduce.at (Useless Nonterminals): Adjust.
10159
10160 2001-11-30 Akim Demaille <akim@epita.fr>
10161
10162 * src/reduce.c: Various comment/formatting changes.
10163 (nonterminals_reduce): New, extracted from...
10164 (reduce_grammar_tables): here.
10165 (reduce_grammar): Call nonterminals_reduce.
10166
10167 2001-11-29 Paul Eggert <eggert@twinsun.com>
10168
10169 * src/bison.simple (YYSTACK_REALLOC): Remove.
10170 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
10171 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
10172 New macros.
10173 (union yyalloc): New type.
10174 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
10175 an arbitrary restriction on hosts where size_t is wider than int.
10176
10177 (yyparse): Don't dump core if alloca or malloc fails; instead, report
10178 a parser stack overflow. Allocate just one block of memory for all
10179 three stacks, instead of allocating three blocks; this typically is
10180 faster and reduces fragmentation.
10181
10182 Do not limit the number of items in the stack to a value that fits
10183 in 'int', as this is an arbitrary limit on hosts with 64-bit
10184 size_t and 32-bit int.
10185
10186 2001-11-29 Marc Autret <autret_m@epita.fr>
10187
10188 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
10189 of defining YYERROR_VERBOSE.

10195 (parse_skel_decl): Use it.
10196 * src/lex.h: Add its prototype.
10197 * src/lex.c (literalchar): Become not static.
10198
10199 2001-11-28 Marc Autret <autret_m@epita.fr>
10200
10201 * src/output.h: And put its extern declaration here.

10203 (prepare): Echo name modification.
10204 * src/getargs.h: Clean its extern declaration.
10205 * src/getargs.c (error_verbose_flag): Remove.
10206 (getargs): Remove case 'e'.

10208 percent option.
10209 Include output.h.
10210
10211 * src/reader.c (read_declarations): Remove case tok_include.
10212 (parse_include_decl): Remove.
10213 * src/lex.h (token_t): Remove tok_include.
10214 * src/options.c (option_table): 'include' is now a simple command line
10215 option.

10511 2001-11-19 Akim Demaille <akim@epita.fr>
10512

10516 (print_actions): Don't output the actions as part of the nodes,
10517 since that's the job of the edges.

10611 * tests/calc.at, tests/output.at, tests/regression.at,
10612 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
10613 now the tests are run in private dirs, therefore AC_CLEANUP and
10614 family can be simplified to 0-ary.
10615 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
10616 use abs. path to find config.h.
10617 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
10618 stderr, there can be way too much random noise.
10619 Instead pass -Werror to GCC and rely on the exit status.

10635
10636 * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):

10639 braces to pacify GCC's warnings for `if () if () {} else {}'.
10640 * src/lex.c (parse_percent_token): Replace equal_offset with
10641 arg_offset.
10642 arg is const.

11569

11571 obstack. It was done too late here.
11572
11573 * src/reader.c (parse_macro_decl): Fix. Use of the macro obstack was

11626 function should now be in the skeletons.
11627 (output_trailers): Remove.

11653 first step in making Bison's output process (a lot) more flexible.
11654 (output_parser): Use the macro table.

11981 2001-02-21 Akim Demaille <akim@epita.fr>
11982
11983 * src/reader.c (gensym): `gensym_count' is your own.

11988
11989 * src/conflicts.c (conflict_report): Be sure not to append to res

11996 New, from fileutils 4.0.37.
11997 * configure.in: Require Autoconf 2.49c. I took some time before
11998 making this decision. This is the only way out for portability
11999 issues in Bison, it would mean way too much duplicate effort to
12000 import in Bison features implemented in 2.49c since 2.13.
12001 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

12019
12020 * src/lex.h: Rename all the tokens:
12021 s/\bENDFILE\b/tok_eof/g;
12022 s/\bIDENTIFIER\b/tok_identifier/g;
12023 etc.

12035
12036 * src/lex.c (percent_table): Also accept `%yacc',
12037 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

12042 * src/reader.c (read_declarations): Adjust.
12043 * src/files.c (open_files): Don't call `compute_base_names', don't
12044 compute `attrsfile' since they depend upon data which might be
12045 *in* the input file now.
12046 (output_files): Do it here.
12047 * src/output.c (output_headers): Document the fact that this patch
12048 introduces a guaranteed SEGV for semantic parsers.

12075 2000-12-20 Akim Demaille <akim@epita.fr>
12076

12113

12150 2000-12-19 Akim Demaille <akim@epita.fr>
12151
12152 * src/files.c (open_files): Yipee! We no longer need all the code
12153 looking for `/tmp' since we have no tmp file.

12235 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
12236 argument `data' for consistency with the prototypes.
12237 Qualify it `const'.
12238 (obstack_copy, obstack_copy0): Rename the second argument as

12386 properly.
12387
12388 2000-10-04 Akim Demaille <akim@epita.fr>
12389
12390 * src/reader.c (parse_expect_decl): Keep `count' within the size
12391 of `buffer'.
12392 From Neil Booth.
12393
12394 2000-10-02 Paul Eggert <eggert@twinsun.com>
12395
12396 * bison.s1 (yyparse): Assign the default value
12397 unconditionally, to avoid a GCC warning and make the parser a
12398 tad smaller.
12399
12400 2000-10-02 Akim Demaille <akim@epita.fr>
12401
12402 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
12403 options.
12404
12405 2000-10-02 Akim Demaille <akim@epita.fr>
12406
12407 * src/derives.c, src/print.c, src/reduce.c: To ease the
12408 translation, move some `\n' out of the translated strings.
12409
12410 2000-10-02 Akim Demaille <akim@epita.fr>
12411
12412 The location tracking mechanism is precious for parse error
12413 messages. Nevertheless, it is enabled only when `@n' is used in
12414 the grammar, which is a different issue (you can use it in error
12415 message, but not in the grammar per se). Therefore, there should
12416 be another means to enable it.
12417
12418 * src/getargs.c (getargs): Support `--locations'.
12419 (usage): Report it.
12420 * src/getargs.h (locationsflag): Export it.
12421 * src/lex.c (percent_table): Support `%locations'.
12422 * src/reader.c (yylsp_needed): Remove this variable, now replaced
12423 with `locationsflag'.
12424 * doc/bison.texinfo: Document `--locations' and `%locations'.
12425 Sort the options.
12426 * tests/calc.m4: Test it.
12427
12428 For regularity of the names, replace each
12429 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
12430 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
12431 In addition replace each `flag' with `_flag'.
12432
12433 2000-10-02 Akim Demaille <akim@epita.fr>
12434
12435 Also test parse error messages, including with YYERROR_VERBOSE.
12436
12437 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
12438 associative).
12439 Use it to check the computations.
12440 Use it to check `nonassoc' is honored.
12441 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
12442 `--yyerror-verbose'.
12443 (_AT_CHECK_CALC): Adjust to this option.
12444 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
12445
12446 2000-10-02 Akim Demaille <akim@epita.fr>
12447
12448 Test also `--verbose', `--defines' and `--name-prefix'. Testing
12449 the latter demonstrates a flaw in the handling of non debugging
12450 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
12451 was used in order to simplify:
12452
12453 #if YYDEBUG
12454 if (yydebug)
12455 {
12456 ...
12457 }
12458 #endif
12459
12460 into
12461
12462 if (yydebug)
12463 {
12464 ...
12465 }
12466
12467 unfortunately this leads to a CPP conflict when
12468 `--name-prefix=foo' is used since it produces `#define yydebug
12469 foodebug'.
12470
12471 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
12472 (YYDPRINTF): New macro.
12473 Spread its use.
12474 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
12475 the bison options.
12476 Also test `--verbose', `--defines' and `--name-prefix'.
12477
12478 2000-10-02 Akim Demaille <akim@epita.fr>
12479
12480 Improve the readability of the produced parsers.
12481
12482 * src/bison.s1: Formatting changes.
12483 Improve the comment related to the `$' mark.
12484 (yydefault): Don't fall through to `yyresume': `goto' there.
12485 * src/output.c (output_parser): When the `$' is met, skip the end
12486 of its line.
12487 New variable, `number_of_dollar_signs', to check there's exactly
12488 one `$' in the parser skeleton.
12489
12490 2000-10-02 Akim Demaille <akim@epita.fr>
12491
12492 * lib/xstrdup.c: New file, from the fileutils.
12493 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
12494 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
12495 instead of strlen + xmalloc + strcpy.
12496 * src/symtab.c (copys): Remove, use xstrdup instead.
12497
12498 2000-10-02 Akim Demaille <akim@epita.fr>
12499
12500 * src/gram.h (associativity): New enum type which replaces the
12501 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
12502 `right_assoc', `left_assoc' and `non_assoc'.
12503 Adjust all dependencies.
12504 * src/reader.c: Formatting changes.
12505 (LTYPESTR): Don't define it, use it as a literal in
12506 `reader_output_yylsp'.
12507 * src/symtab.h (symbol_class): New enum type which replaces the
12508 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
12509 `sunknown', `stoken and `snterm'.
12510
12511 2000-10-02 Akim Demaille <akim@epita.fr>
12512
12513 * src/getargs.c (fixed_outfiles): Rename as...
12514 (yaccflag): for consistency and accuracy.
12515 Adjust dependencies.
12516
12517 2000-10-02 Akim Demaille <akim@epita.fr>
12518
12519 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
12520 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
12521 difficult and introduced a lot of core dump. It turns out that
12522 Bison used an implementation of `xmalloc' based on `calloc', and
12523 at various places it does depend upon the initialization to 0. I
12524 have not tried to isolate the pertinent places, and all the former
12525 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
12526 someone should address this issue.
12527
12528 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
12529 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

12574 Propagate its inclusion.
12575
12576 2000-10-02 Akim Demaille <akim@epita.fr>

12624 YYDEFACT, that makes it possible for this function to use
12625 output_short_table.
12626
12627 2000-10-02 Akim Demaille <akim@epita.fr>
12628
12629 `user_toknums' is output as a `short[]' in `output.c', while it is
12630 defined as a `int[]' in `reader.c'. For consistency with the
12631 other output tables, `user_toknums' is now defined as a table of
12632 shorts.
12633
12634 * src/reader.c (user_toknums): Be a short table instead of an int
12635 table.

12673 inclusion.
12674 Don't define PARAMS.
12675 * src/system.h: Define PARAMS.

12678 definitions in config.h.
12679
12680 2000-09-20 Akim Demaille <akim@epita.fr>

12895
12896 Change the handling of @s so that they behave exactly like $s.
12897 There is now a pseudo variable @$ (readble and writable), location
12898 of the lhs of the rule (by default ranging from the location of
12899 the first symbol of the rhs, to the location of the last symbol,
12900 or, if the rhs is empty, YYLLOC).

12904 (yyparse): When providing a default semantic action, provide a

12935 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
12936 One `#if YYDEBUG' remains, since it uses variables which are
12937 defined only if `YYDEBUG != 0'.
12938

13663 way to specify the flags -n, -l, and -r. Also added hooks for
