[bison.git] / ChangeLog
1 2003-02-01 Paul Eggert <eggert@twinsun.com>
2
3 Version 1.875a.
4
5 * po/LINGUAS: Add ms.
6
7 2003-01-30 Akim Demaille <akim@epita.fr>
8
9 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10
11 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12
13 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
14 of $1.
15
16 Changes in response to error report by S. Eken: GLR mode does not
17 handle negative $ indices or $ indices in embedded rules correctly.
18 See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
19
20 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
21 (b4_rhs_location): Ditto.
22 (yyfill): New function to copy from stack tree into array
23 incrementally.
24 (yyuserAction): Modify to allow incremental move of semantic values
25 to rhs array when in GLR mode.
26 Define YYFILL to use in user-defined actions to fill semantic array
27 as needed.
28 Remove dummy use of yystack, as there is now a guaranteed use.
29 (yydoAction): Modify to allow incremental move of semantic values
30 to rhs array when in GLR mode.
31 (yyresolveAction): Ditto.
32 (yyglrShiftDefer): Update comment.
33 (yyresolveStates): Use X == NULL for pointers, not !X.
34 (yyglrReduce): Ditto.
35 (yydoAction): Ditto
36
37 * tests/glr-regr1.at: Rename to ...
38 * tests/glr-regression.at: Add new regression test for the problems
39 described above (adapted from S. Eken).
40 Update copyright notice.
41 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
42 * tests/Makefile.am: Ditto.
43
44 2003-01-28 Paul Eggert <eggert@twinsun.com>
45
46 * data/lalr1.cc: Do not use @output_header_name@ unless
47 b4_defines_flag is set. This fixes two bugs reported by
48 Tim Van Holder in
49 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
50 and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
51
52 2003-01-21 Paul Eggert <eggert@twinsun.com>
53
54 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
55 we don't need to worry about yyerrlab1 being reported as an
56 "unused label" by non-GCC C compilers. The downside is that if
57 locations are used then a couple of statements are duplicated each
58 time YYERROR is invoked, but the upside is that the warnings
59 should vanish.
60 (yyerrlab1): Move code to YERROR.
61 (yyerrlab2): Remove. Change uses back to yyerrlab1.
62 This reverts some of the 2002-12-27 change.
63
64 2003-01-17 Paul Eggert <eggert@twinsun.com>
65
66 * src/output.c (symbol_printers_output): Fix typo that led
67 to core dump. Problem reported by Antonio Rus in
68 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
69
70 2003-01-13 Akim Demaille <akim@epita.fr>,
71 Quoc Peyrot <chojin@lrde.epita.fr>,
72 Robert Anisko <anisko_r@lrde.epita.fr>
73
74 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
75 when the stacks contain one element, as the loop would otherwise
76 free the last state, and then use the top state (the one we just
77 popped). This means that the initial elements will not be freed
78 explicitly, as is the case in yacc.c; it is not a problem, as
79 these elements have fake values.
80
81 2003-01-11 Paul Eggert <eggert@twinsun.com>
82
83 * NEWS: %expect-violations are now just warnings, reverting
84 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
85 bootstrapping problem reported by Matthias Klose; see
86 <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
87 * src/conflicts.c (conflicts_print): Likewise.
88 * tests/conflicts.at (%expect not enough, %expect too much,
89 %expect with reduce conflicts): Likewise.
90 * doc/bison.texinfo (Expect Decl): Document this. Also mention
91 that the warning is enabled if the number of conflicts changes
92 (not necessarily increases).
93
94 * src/getargs.c (version): Update copyright year.
95
96 2003-01-09 Akim Demaille <akim@epita.fr>
97
98 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
99
100 2003-01-08 Paul Eggert <eggert@twinsun.com>
101
102 * Makefile.maint (WGETFLAGS):
103 New macro, containing "-C off" to disable proxy caches.
104 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
105 (rel-check): Use $(WGET) instead of wget.
106
107 2003-01-06 Paul Eggert <eggert@twinsun.com>
108
109 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
110 the GLR paper of Scott, Johnstone and Hussain.
111
112 2003-01-04 Paul Eggert <eggert@twinsun.com>
113
114 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
115 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
116 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
117 (EXTRA_LIBRARIES): New var, for liby.a.
118 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
119 (EXTRA_SCRIPTS): New var, for yacc.
120
121 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
122 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
123 Problem reported by Nelson H. F. Beebe.
124
125 2003-01-03 Paul Eggert <eggert@twinsun.com>
126
127 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
128 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
129 when compiling Bison 1.875's `bitset bset = obstack_alloc
130 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
131
132 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
133 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
134 grow to a huge size with typical invocation.
135
136 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
137 Use the pattern recommended by Autoconf 2.57, except also protect
138 against double-definition.
139 * src/system.h: Likewise.
140 Portability issues reported by Nelson H. F. Beebe.
141
142 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
143 All uses changed. Provide a definition in both C and C++.
144 (yytrue, yyfalse): Define even if defined (__cplusplus).
145
146 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
147 Reported by Nelson H. F. Beebe.
148
149 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
150
151 2003-01-02 Paul Eggert <eggert@twinsun.com>
152
153 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
154 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
155 Bug reported by Nelson H. F. Beebe.
156
157 2003-01-01 Paul Eggert <eggert@twinsun.com>
158
159 * Version 1.875.
160
161 2002-12-30 Paul Eggert <eggert@twinsun.com>
162
163 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
164 Moved here from...
165 (<INITIAL>","): Here. This causes stray "," to be treated
166 more uniformly.
167
168 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
169 last brace in braced code when not in Yacc mode, for compatibility
170 with Bison 1.35. This resurrects the 2001-12-15 patch to
171 src/reader.c.
172
173 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
174 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
175
176 2002-12-28 Paul Eggert <eggert@twinsun.com>
177
178 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
179 that of SYM's type. This fixes Debian bug 168069, reported by
180 Thomas Olsson.
181
182 2002-12-28 Paul Eggert <eggert@twinsun.com>
183
184 Version 1.75f.
185
186 Switch back to the Yacc style of conflict reports, undoing some
187 of the 2002-07-30 change.
188 * doc/bison.texinfo (Understanding): Use Yacc style for
189 conflict reports. Also, use new way of locating rules.
190 * src/conflicts.c (conflict_report):
191 Renamed from conflict_report_yacc, removing the old
192 'conflict_report'. Translate the entire conflict report at once,
193 so that we don't assume that "," has the same interpretation in
194 all languages.
195 (conflicts_output): Use Yacc-style conflict report for each state,
196 instead of our more-complicated style.
197 (conflicts_print): Use Yacc-style conflict report, except print
198 the input file name when not emulating Yacc.
199 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
200 Conflicted Reduction, %expect not enough, %expect too much,
201 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
202 * tests/existing.at (GNU Cim Grammar): Likewise.
203 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
204
205 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
206 fatal): Don't invoke fflush; it's not needed and it might even be
207 harmful for stdout, as stdout might not be open.
208 * src/reduce.c (reduce_print): Likewise.
209
210 2002-12-27 Paul Eggert <eggert@twinsun.com>
211
212 Fix a bug where error locations were not being recorded correctly.
213 This problem was originally reported by Paul Hilfinger in
214 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
215
216 * data/yacc.c (yyparse): New local var yylerrsp, to record the
217 top of the location stack's error locations.
218 (yyerrlab): Set it. When discarding a token, push its location
219 onto yylerrsp so that we don't lose track of the error's end.
220 (yyerrlab1): Now is only the target of YYERROR, so that we can
221 properly record the location of the action that failed. For GCC
222 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
223 GCC warning about yyerrlab1 being unused if YYERROR is unused.
224 (yyerrlab2): New label, which yyerrlab now falls through to.
225 Compute the error's location by applying YYLLOC_DEFAULT to
226 the locations of all the symbols that went into the error.
227 * doc/bison.texinfo (Location Default Action): Mention that
228 YYLLOC_DEFAULT is also invoked for syntax errors.
229 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
230 Error locations include the locations of all the tokens that were
231 discarded, not just the last token.
232
233 2002-12-26 Paul Eggert <eggert@twinsun.com>
234
235 * src/files.c: Include quote.h.
236 (compute_output_file_names): Warn if we detect conflicting
237 outputs to the same file. This should catch the misunderstanding
238 exemplified by Debian Bug 165349, reported by Bruce Stephens..
239
240 * src/conflicts.c (conflicts_print): If the user specifies
241 "%expect N", report an error if there are any reduce/reduce
242 conflicts. This is what the manual says should happen.
243 This fixes Debian bug 130890, reported by Anthony DeRobertis.
244 * tests/conflicts.at (%expect with reduce conflicts): New test.
245
246 Don't use m4_include on relative file names, as it doesn't work as
247 desired if there happens to be a file with that name under ".".
248
249 * m4sugar/version.m4: Remove; it was included but it wasn't used.
250 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
251 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
252 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
253 * src/output.c (output_skeleton): Use full path names when
254 specifying a file to include; don't rely on include path, as
255 it's unreliable when the working file contains a file with
256 that name.
257
258 2002-12-25 Paul Eggert <eggert@twinsun.com>
259
260 Remove obsolete references to bison.simple and bison.hairy.
261 Problem mentioned by Aubin Mahe in
262 <http://mail.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
263 * data/glr.c: Comment fix.
264 * doc/bison.1: Remove references. Also, mention "yacc".
265
266 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
267 with -g option.
268
269 * src/parse-gram.y (declaration): Use enum "report_states" rather
270 than its numeric value 1.
271
272 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
273 opening a new one. This fixes Debian bug 165349, reported by
274 Bruce Stephens.
275
276 2002-12-24 Paul Eggert <eggert@twinsun.com>
277
278 Version 1.75e.
279
280 * Makefile.maint (cvs-update): Don't assume that the shell
281 supports $(...), as Solaris sh doesn't.
282
283 * src/parse-gram.y (lloc_default): Remove test for empty
284 nonterminals at the end, since it didn't change the result.
285
286 2002-12-24 Paul Eggert <eggert@twinsun.com>
287
288 If the user does not define YYSTYPE as a macro, Bison now declares it
289 using typedef instead of defining it as a macro. POSIX requires this.
290 For consistency, YYLTYPE is also declared instead of defined.
291
292 %union directives can now have a tag before the `{', e.g., the
293 directive `%union foo {...}' now generates the C code
294 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
295 The default union tag is `YYSTYPE', for compatibility with Solaris 9
296 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
297 instead of `yyltype'.
298
299 `yystype' and `yyltype' are now obsolescent macros instead of being
300 typedefs or tags; they are no longer documented and will be
301 withdrawn in a future release.
302
303 * data/glr.c (b4_location_type): Remove.
304 (YYSTYPE): Renamed from yystype.
305 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
306 (struct YYLTYPE): Renamed from struct yyltype.
307 (YYLTYPE): Renamed from yyltype.
308 (yyltype, yystype): New (and obsolescent) macros,
309 for backward compatibility.
310 * data/yacc.c: Likewise.
311
312 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
313 does not specify a union tag. This is for compatibility with
314 Solaris 9 yacc.
315
316 * src/parse-gram.y (add_param): 2nd arg is now char * not char
317 const *, since it is now modified by stripping surrounding { }.
318 (current_braced_code): Remove.
319 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
320 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
321 trailing " {...}". Now of type <chars>.
322 (grammar_declaration): Adjust to bundled tokens.
323 (code_content): Remove; stripping is now done by add_param.
324 (print_token_value): Print contents of bundled tokens.
325 (token_name): New function.
326
327 * src/reader.h (braced_code, current_braced_code): Remove.
328 (token_name): New decl.
329
330 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
331 token_type, not braced_code code_kind. All uses changed.
332 (SC_PRE_CODE): New state, for scanning after a keyword that
333 has (or usually has) an immediately-following braced code.
334 (token_type): New local var, to keep track of which token type
335 to return when scanning braced code.
336 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
337 <INITIAL>"%parse-param", <INITIAL>"%printer",
338 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
339 instead of returning a token type immediately.
340 (<INITIAL>"{"): Set token type.
341 (<SC_BRACED_CODE>"}"): Use it.
342 (handle_action_dollar, handle_action_at): Now returns bool
343 indicating success. Fail if ! current_rule; this prevents a core dump.
344 (handle_symbol_code_dollar, handle_symbol_code_at):
345 Remove; merge body into caller.
346 (handle_dollar, handle_at): Complain in invalid contexts.
347
348 * NEWS, doc/bison.texinfo: Document the above.
349 * NEWS: Fix years and program names in copyright notice.
350
351 2002-12-17 Paul Eggert <eggert@twinsun.com>
352
353 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
354 Reporting, Table of Symbols): Omit mentions of %lex-param and
355 %parse-param from the documentation for now.
356
357 2002-12-15 Paul Eggert <eggert@twinsun.com>
358
359 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
360 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
361 lookahead symbol, and which sets yychar in parser actions) and it
362 disagreed with the Bison documentation. Bug
363 reported by Andrew Walrond.
364
365 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
366 as the caller now does that.
367 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
368 (YYEMPTY): Parenthesize right hand side, since others use it.
369 (yyparse): Don't assume that our generated code is the only code
370 that sets yychar.
371
372 2002-12-13 Paul Eggert <eggert@twinsun.com>
373
374 Version 1.75d.
375
376 POSIX requires a "yacc" command.
377 * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
378 (MOSTLYCLEANFILES): Add yacc.
379 (yacc): New rule.
380 * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
381 as an alias for bison y.
382
383 * po/LINGUAS: Add da.
384
385 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around
386 problem with latest <getopt.h>.
387 (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro.
388
389 * doc/fdl.texi: Upgrade to 1.2.
390 * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
391 lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,
392 lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with
393 gnulib.
394 * config/install-sh: Sync with autotools.
395
396 Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
397 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
398 * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
399 locations are requested.
400 (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
401 locations are requested.
402
403 2002-12-12 Paul Eggert <eggert@twinsun.com>
404
405 Remove unportable casts and storage allocation tricks.
406 While we're at it, remove almost all casts, since they
407 usually aren't needed and are a sign of trouble.
408
409 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
410
411 * src/derives.c (derives_compute): Do not subtract NTOKENS from
412 the pointer DSET returned by malloc; this isn't portable.
413 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
414 Similarly for DERIVES.
415 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
416 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
417 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
418
419 * src/derives.c (derives_compute): Do not bother invoking
420 int_of_rule_number, since rule numbers are integers.
421
422 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
423 rather than XMALLOC (char, N).
424
425 * src/files.c (filename_split): Rewrite to avoid cast.
426
427 * src/gram.h (symbol_number_as_item_number,
428 item_number_as_symbol_number, rule_number_as_item_number,
429 item_number_as_rule_number):
430 Now inline functions rather than macros, to avoid casts.
431 * src/state.h (state_number_as_int): Likewise.
432 * src/tables.c (state_number_to_vector_number,
433 symbol_number_to_vector_number): Likewise.
434
435 * src/gram.h (int_of_rule_number): Remove; no longer used.
436
437 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
438 since the resulting storage is always stored into.
439
440 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
441 where it's needed.
442
443 * src/muscle_tab.c (muscle_m4_output):
444 Now inline. Return bool, not int.
445 * src/state.c (state_compare): Likewise.
446 * src/symtab.c (symbol_check_defined,
447 symbol_check_alias_consistency, symbol_pack, symbol_translation,
448 hash_compare_symbol, hash_symbol):
449 Likewise.
450 * src/uniqstr.c (uniqstr_print): Likewise.
451 * src/muscle_tab.c (muscle_m4_output_processor):
452 New function, to avoid casts.
453 * src/state.c (state_comparator, stage_hasher): Likewise.
454 * src/symtab.c (symbol_check_defined_processor,
455 symbol_check_alias_consistency_processor, symbol_pack_processor,

457 hash_symbol_hasher): Likewise.
458 * src/uniqstr.c (uniqstr_print_processor): Likewise.
459 * src/muscle_tab.c (muscles_m4_output):
460 Use new functions instead of casting old functions unportably.

466
467 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
468 var instead of casting to long, to avoid casts.

470 have to worry about alloca.
471 * src/state.c (state_hash_lookup): Likewise.
472
473 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char

477 STATE_ALLOC): Remove.
478 (transitions_new, errs_new, reductions_new, state_new): Use malloc
479 rather than calloc, and use offsetof to avoid allocating slightly
480 too much storage.
481 (state_new): Initialize all members.
482
483 * src/state.c (state_hash): Use unsigned accumulator, not signed.
484
485 * src/symtab.c (symbol_free): Remove; unused.
486 (symbol_get): Remove cast in lhs of assignment.

491 (symbol_processor): Remove.
492 (symbols_do): Remove decl; now static.
493

496 (<inttypes.>, <stdint.h>): Include if available.
497 (uintptr_t): New type, if system lacks it.
498 (CALLOC, MALLOC, REALLOC): New macros.

507
508 * src/vcg.h: Correct misspellings.
509
510 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
511
512
513 * src/getargs.c (getargs): Don't assume EOF == -1.
514
515 2002-12-09 Paul Eggert <eggert@twinsun.com>
516
517 Change identifier spellings to avoid collisions with names
518 that are reserved by POSIX.
519
520 Don't use names ending in _t, since POSIX reserves them.
521 For consistency, remove _e and _s endings -- they're weren't
522 needed to remove ambiguity. All uses changed.
523 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
524 turn was just renamed from struniq_t.
525 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
526 which in turn was just renamed from struniq_processor_t.

598 value_t_as_yystype -> value_as_yystype.
599
600 Don't include <errno.h> in the mainstream code, since it
601 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
602 * lib/get-errno.c, lib/get-errno.h: New files.
603 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,
604 get-errno.c.

613 (TAB_EXT): Renamed from EXT_TAB.
614 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
615
616 Avoid str[a-z]*, since <string.h> reserves that name space.
617 Change all instances of "struniq" in names to "uniqstr", and
618 likewise for "STRUNIQ" and "UNIQSTR".
619 * src/uniqstr.c: Renamed from src/struniq.c.
620 * src/uniqstr.h: Renamed from src/struniq.h.
621 * src/Makefile.am (bison_SOURCES): Adjust to these renamings.

651 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
652 G_NODE_ALIGNEMENT.
653
654

656 for consistency with other names.
657 * lib/timevar.h (timevar_report): New decl.
658 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
659
660
661 Sort include-file uses.
662
663 Reorder all include files under src to be in the order "system.h".
664 then the ../lib include files in angle brackets (alphabetized),
665 then the . include files in double-quotes (alphabetized). Fix
666 dependency breakages encountered in this process, as follows:
667 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
668 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
669 * src/state.h: Include "symtab.h".
670
671 2002-12-08 Paul Eggert <eggert@twinsun.com>
672
673 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
674 since this causes problems when __file__ contains character
675 sequences like "@" that are treated specially by src/scan-skel.l.
676 Instead, just use the file's basename. This fixes the bug
677 reported by Martin Mokrejs in
678 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
679
680 2002-12-06 Paul Eggert <eggert@twinsun.com>
681
682 Add support for rules that do not have trailing semicolons, as
683 POSIX requires. Improve the quality of locations in Bison
684 diagnostics.
685
686 * src/location.c: Include <quotearg.h>.
687 (empty_location): Now const.
688 (location_print): New function. Follow the recommendation of the
689 GNU Coding Standards for locations that span file boundaries.
690 * src/location.h: Do not include <quotearg.h>; no longer needed.
691 (boundary): New type.
692 (location_t): Use it. This allows locations to span file boundaries.
693 All member uses changed: file -> start.file or end.file (as needed),
694 first_line -> start.line, first_column -> start.column,
695 last_line -> end.line, last_column -> end.column.
696 (equal_boundaries): New function.
697 (LOCATION_RESET, LOCATION_STEP): Remove.
698 (LOCATION_PRINT): Remove. All callers changed to use location_print.
699 (empty_location): Now const.
700 (location_print): New decl.
701 * src/parse-gram.y (lloc_default): New function, which handles
702 empty locations more accurately.
703 (YYLLOC_DEFAULT): Use it.
704 (%token COLON): Remove.
705 (%token ID_COLON): New token.
706 (rules): Use it.

711 (rules_or_grammar_declaration): Remove trailing semicolon.
712 (semi_colon.opt): Remove.
713 * src/reader.h: Include location.h.
714 (scanner_cursor): New decl.
715 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
716 rolling our own.
717 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
718 of *loc.
719 (STEP): Remove. No longer needed, now that adjust_location does
720 the work. All uses removed.
721 (scanner_cursor): New var.
722 (adjust_location): Renamed from extend_location. It now sets
723 *loc and adjusts the scanner cursor. All uses changed.
724 Don't bother testing for CR.
725 (handle_syncline): Remove location arg; now updates scanner cursor.
726 All callers changed.
727 (unexpected_end_of_file): Now accepts start boundary of token or
728 comment, not location. All callers changed. Update scanner cursor,
729 not the location.
730 (SC_AFTER_IDENTIFIER): New state.
731 (context_state): Renamed from c_context. All uses changed.
732 (id_loc, code_start, token_start): New local vars.
733 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
734 processing of Yacc white space and equivalents here.
735 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
736 instead of returning ID immediately, since we need to search for
737 a subsequent colon.
738 (<INITIAL>"'", "\""): Save token_start.
739 (<INITIAL>"%{", "{", "%%"): Save code_start.
740 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
741 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
742 BEGIN context_state at end, not INITIAL.
743 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
744 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
745 Return correct token start.
746 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
747 the start of a character, string or multiline comment is found.
748 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
749 Reduction): Adjust reported locations to match the more-precise
750 results now expected.
751 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
752 * tests/reduce.at (Useless Rules, Reduced Automaton,
753 Underivable Rules): Likewise.
754 * tests/regression.at (Invalid inputs): No longer `expecting ";"
755 or "|"' now that so many other tokens are allowed by the new grammar.
756
757 * src/complain.h (current_file): Remove duplicate decl;
758 current_file is now owned by files.h.
759 * src/complain.c, src/scan-gram.l: Include files.h.
760
761 2002-12-06 Paul Eggert <eggert@twinsun.com>
762
763 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
764 promotes to int; it might be unsigned int.
765 * data/yacc.c (yy_reduce_print): Likewise.
766
767 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
768 be #defined in the prologue, not in the Bison declarations.
769 This fixes Debian Bug 102878, reported by Shaul Karl.
770
771 2002-12-02 Paul Eggert <eggert@twinsun.com>
772
773 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
774 * lib/strtoul.c: New file, from gnulib.
775 This fixes a porting bug reported by Peter Klein in
776 <http://mail.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
777
778 2002-11-30 Paul Eggert <eggert@twinsun.com>
779
780 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
781 and put only a forward declaration in the prologue. This is for
782 consistency with the other scanner helper functions.
783
784 Type clashes now generate warnings, not errors, since it
785 appears that POSIX may allow some grammars with type clashes.
786 * src/reader.c (grammar_current_rule_check): Warn about
787 type clashes instead of complaining.
788 * tests/input.at (Type Clashes): Expect warnings, not complaints.
789
790 Add Yacc library, since POSIX requires it.
791 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
792 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
793 * lib/main.c, lib/yyerror.c: New files.
794
795 gram_error can be static; it need not be extern.
796 * src/reader.h (gram_error): Remove decl.
797 * src/parse-gram.y (gram_error): Now static. Add static decl.
798 (print_token_value): Omit parameter names from forward decl,
799 for consistency.
800
801 2002-11-29 Paul Eggert <eggert@twinsun.com>
802
803 * doc/bison.texinfo: Emphasize that yylex and yyerror must
804 be declared before being used. E.g., one should typically
805 declare them in the prologue. Use GNU coding style in examples.
806 Put "const" consistently after the type it modifies. Mention
807 that C99 supports "inline". Mention that yyerror traditionally
808 returns "int".
809
810 %parse-param and %lex-param now take just one argument, the
811 declaration; the argument name is deduced from the declaration.
812
813 * doc/bison.texinfo (Parser Function, Pure Calling, Error
814 Reporting, Table of Symbols): Document this.
815 * src/parse-gram.y (add_param): New function.
816 (COMMA): Remove.
817 (declaration): Implement new rule for %parse-param and %lex-param.
818 * src/scan-gram.l: "," now elicits a warning, rather than being
819 a token; this is more compatible with byacc.
820 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
821
822 2002-11-27 Paul Eggert <eggert@twinsun.com>
823
824 Rename identifiers to avoid real and potential collisions.
825
826 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
827 to avoid collision with lex macro described by Bruce Lilly in
828 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
829 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
830 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
831 * src/parse-gram.y (print_token_value): Renamed from yyprint.
832 All uses changed.
833 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
834 The name "yycontrol" violates the name space rules, and this stuff
835 wasn't being used anyway.
836 (input): Remove action; this stuff wasn't being used.
837 (gram_error): Rename local variable yylloc -> loc.
838 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
839 (YY_DECL): Don't use "yy" at start of local variables.
840 All uses changed, e.g., yylloc -> loc.
841 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
842 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
843 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
844 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
845
846 * src/parse-gram.y (gram_error): loc is now const *.
847 * src/reader.h (gram_error): Likewise.
848
849 2002-11-24 Paul Eggert <eggert@twinsun.com>
850
851 Version 1.75c.
852
853 * tests/actions.at (Actions after errors): Use an output format
854 more similar to that of the Printers and Destructors test.
855 Test the position of the ';' token too.
856 (Printers and Destructors): Likewise.
857 (Printers and Destructors: %glr-parser): Remove for now, to avoid
858 unnecessarily alarming people when the test fails.
859
860 * data/yacc.c (yyerrlab1): Move this label down, so that the
861 parser does not discard the lookahead token if the user code
862 invokes YYERROR. This change is required for POSIX conformance.
863
864 * lib/error.c: Sync with gnulib.
865
866 2002-11-22 Paul Eggert <eggert@twinsun.com>
867
868 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
869 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
870 * lib/xmalloc.c: Likewise.
871
872 2002-11-20 Paul Eggert <eggert@twinsun.com>
873
874 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
875
876 2002-11-20 Paul Eggert <eggert@twinsun.com>
877
878 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
879 should use `if (! x) abort ();' rather than `assert (x);', and
880 anyway it's one less thing to worry about configuring.
881
882 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
883 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
884 and replace all instances of assert with abort.

886 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
887
888 * data/glr.c (yydoAction, yyglrReduce, yysplitStack, yyresolveStates,
889 yyresolveAction, yyprocessOneStack): Use abort rather than assert.
890 * lib/hash.c (hash_lookup, hash_get_first, hash_get_next,
891 hash_find_entry, hash_rehash, hash_insert): Likewise.
892 * src/conflicts.c (resolve_sr_conflict): Likewise.

920
921 2002-11-18 Paul Eggert <eggert@twinsun.com>
922
923 * data/glr.c (yygetLRActions): Replace `yyindex' with
924 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
925 This fixes the regression with Sun ONE Studio 7 cc that I reported in
926 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
927
928 2002-11-18 Akim Demaille <akim@epita.fr>
929
930 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
931 space.
932 From Tim Van Holder.
933
934 2002-11-17 Paul Eggert <eggert@twinsun.com>
935
936 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
937 to "SyntaxError" for consistency with my 2002-11-15 change.
938
939 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
940 not define to {}, since this breaks the common use of `YYDPRINTF
941 ((...));' if a single statement is desired (e.g. before `else').
942 Work around GCC warnings by surrounding corresponding calls with
943 {} if needed.
944 (yyhasResolvedValue): Remove unused function.
945 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
946 loop body.
947 (yyreportSyntaxError): Renamed from yyreportParseError.
948 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
949 All uses changed.
950 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
951 extern when possible. Remove unused initializations.
952
953 2002-11-16 Akim Demaille <akim@epita.fr>
954
955 Augment the similarity between GLR and LALR traces.
956
957 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
958 (YY_REDUCE_PRINT): New.
959 (yyparse): Use them.
960 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
961 YYDPRINT here.
962 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
963 state reached after the reduction/recovery, since...
964 (yyparse, yyprocessOneStack): Report the state we are entering in.
965
966 2002-11-16 Akim Demaille <akim@epita.fr>
967
968 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
969 Add support for --trace=skeleton.
970 * src/scan-skel.l: %option debug.
971 Scan strings of non-@ or \n instead of character by character.
972 (scan_skel): Handle trace_skeleton.
973 (QPUTS): New.
974 (@output_parser_name@, @output_header_name@): ``Restore'' their
975 support (used to be M4 macros).
976 * data/yacc.c: Quote larger chunks, a la glr.c.
977 * data/lalr1.cc: Likewise.
978 The header guards are no longer available, so use some other
979 string than `YYLSP_NEEDED'.
980
981 2002-11-16 Akim Demaille <akim@epita.fr>
982
983 Make the ``Printers and Destructors'' test more verbose, taking
984 `yacc.c''s behavior as (possibly wrong) reference.
985
986 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
987 instead of fprint on stdout.
988 Set and report the last_line of the symbols.
989 Consistently display values and locations.
990
991 2002-11-16 Paul Eggert <eggert@twinsun.com>
992
993 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
994
995 2002-11-15 Paul Eggert <eggert@twinsun.com>
996
997 * tests/actions.at (Actions after errors): New test case.
998
999 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
1000 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
1001 tests/action.at, tests/calc.at, tests/conflicts.at,
1002 tests/cxx-type.at, tests/regression.at:
1003 "parse error" -> "syntax error" for POSIX compatibility.
1004 "parsing stack overflow..." -> "parser stack overflow" so
1005 that code matches Bison documentation.
1006
1007 2002-11-15 Akim Demaille <akim@epita.fr>
1008
1009 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
1010 take two BRACED_CODE, not two string_content.
1011 Free the scanner's obstack when we are done.
1012 (code_content): New.
1013 * tests/calc.at: Adjust.
1014 * doc/bison.texinfo: Adjust.
1015 Also, make sure to include the `,' for these declarations.
1016
1017 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
1018
1019 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
1020 definition; avoids potential autoreconf problems.
1021
1022 2002-11-15 Akim Demaille <akim@epita.fr>
1023
1024 Always check the value returned by yyparse.
1025
1026 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
1027 returned by yyparse.
1028 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
1029 Adjust calls.
1030 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
1031 returned by yyparse.
1032
1033 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1034
1035 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
1036 on input.at test.
1037
1038 2002-11-14 Paul Eggert <eggert@twinsun.com>
1039
1040 * src/output.c (output_skeleton): Call xfopen instead of
1041 duplicating xfopen's body.
1042
1043 Fix bugs reported by Nelson H. F. Beebe in
1044 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
1045
1046 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
1047 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
1048 Group compiler. Instead, use "$CC -E bar.c". Include the .h
1049 file twice in the grammar, as an extra check.
1050
1051 * tests/input.at (Torturing the Scanner): Surround the
1052 backslash-newline tests with "#if 0", to make it less likely that
1053 we'll run into compiler bugs. Bring back solitary \ inside
1054 comment, but add a closing comment to work around HP C bug. Don't
1055 test backslash-newline in C character constant.
1056
1057 2002-11-14 Akim Demaille <akim@epita.fr>
1058
1059 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
1060 status of the compiler.
1061 Calling `exit 1' is no longer needed.
1062 Reported by Nelson H. F. Beebe.
1063
1064 2002-11-14 Akim Demaille <akim@epita.fr>
1065
1066 * tests/atlocal.in (CPPFLAGS): We have config.h.
1067 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
1068 New.
1069 * tests/actions.at, tests/calc.at, tests/conflicts.at,
1070 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
1071 * tests/regression.at, tests/torture.at: Use them for all the
1072 grammars that are to be compiled.
1073 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
1074 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
1075 * doc/bison.texinfo (GLR Parsers): Document `inline'.
1076
1077 2002-11-14 Akim Demaille <akim@epita.fr>
1078
1079 * doc/bison.texinfo: Various formatting changes (alignments in
1080 samples, additional @group/@end group, GCS in samples.
1081 Use @deffn instead of simple @table to define the directives,
1082 macros, variables etc.
1083
1084 2002-11-13 Paul Eggert <eggert@twinsun.com>
1085
1086 Fix some bugs reported by Albert Chin-A-Young in
1087 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
1088
1089 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
1090 -o c"; the HP C compiler chatters during compilation.
1091 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
1092 * tests/headers.at (export YYLTYPE): Likewise.
1093
1094 * tests/input.at (Torturing the Scanner): Remove lines containing
1095 solitary backslashes, as they tickle a bug in the HP C compiler.
1096
1097 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
1098 comments, since they're not portable. Use GNU coding style.
1099
1100 2002-11-13 Akim Demaille <akim@epita.fr>
1101
1102 * data/yacc.c: Leave bigger chunks of quoted text.
1103 (YYDSYMPRINTF): New.
1104 Use it to report symbol activities.
1105 * data/glr.c (YYDSYMPRINTF): New.
1106 Use it.
1107
1108 2002-11-12 Paul Eggert <eggert@twinsun.com>
1109
1110 Version 1.75b.
1111
1112 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
1113 (yyglrReduce): Return yyok, not 0.
1114 This should avoid the enumerated-type warnings reported
1115 by Nelson H. F. Beebe in
1116 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
1117
1118 * lib/bbitset.h (BITSET_INLINE): Remove.
1119 * lib/bitset.h [! BITSET_INLINE]: Remove.
1120 (bitset_set, bitset_reset, bitset_test): Rename local vars
1121 to avoid shadowing warnings by GCC.
1122
1123 * data/glr.c (inline): Remove #define. It's the user's
1124 responsibility to #define it away, just like 'const'.
1125 This fixes one of the bugs reported by Nelson H. F. Beebe in
1126 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
1127
1128 * Makefile.maint (po-check): Scan .l and .y files instead of the
1129 .c and the .h files that they generate. This fixes the bug
1130 reported by Tim Van Holder in:
1131 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
1132 Look for N_ as well as for _. Try to avoid matching #define for
1133 N_ and _.
1134 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
1135 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
1136 * src/scan-gram.l: Revamp regular expressions so that " and '
1137 do not confuse xgettext.
1138
1139 * src/struniq.h (struniq_new): Do not declare the return type
1140 to be 'const'; this violates the C standard.
1141 * src/struniq.c (struniq_new): Likewise.
1142
1143 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
1144
1145 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
1146 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
1147 linker.
1148
1149 2002-11-12 Akim Demaille <akim@epita.fr>
1150
1151 * Makefile.maint: Sync with Autoconf:
1152 (local_updates): New.
1153
1154 2002-11-12 Akim Demaille <akim@epita.fr>
1155

1159
1160 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
1161 locations.
1162
1163 2002-11-12 Akim Demaille <akim@epita.fr>
1164
1165 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
1166 not yyvalue.
1167
1168 2002-11-12 Akim Demaille <akim@epita.fr>
1169
1170 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
1171 Use it to test the GLR parser.
1172
1173 2002-11-12 Akim Demaille <akim@epita.fr>
1174
1175 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
1176 defines it.
1177 * data/glr.c (yystos): New.
1178 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
1179 (YYDSYMPRINT): New.

1181 (yyrecoverParseError): Free verbosely the discarded symbols.
1182 * data/yacc.c (yysymprint): Remove, rather...
1183 (b4_yysymprint_generate): invoke.
1184 * data/c.m4 (b4_yysymprint_generate): New.
1185 Accept pointers as arguments, as opposed to the version from
1186 yacc.c.
1187 (b4_yydestruct_generate): Likewise.
1188 * tests/cations.at (Printers and Destructors): Use Bison directives
1189 instead of CPP macros.
1190 Don't rely on internal details.
1191
1192 2002-11-12 Akim Demaille <akim@epita.fr>
1193
1194 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
1195 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
1196 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
1197 it against YYEMPTY and so forth), work on yytoken (i.e., set
1198 it to YYEMPTY etc.).
1199 (yydestruct): Replace with a b4_yydestruct_generate invocation.
1200 (b4_symbol_actions): Remove.
1201 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
1202 for 0, end-of-input.
1203
1204 2002-11-12 Akim Demaille <akim@epita.fr>
1205
1206 * doc/bison.texinfo (Destructor Decl): New.
1207
1208 2002-11-12 Akim Demaille <akim@epita.fr>
1209
1210 * src/tables.c (tables_generate): Use free for pointers that
1211 cannot be NULL, not XFREE.

1217 the file name.
1218
1219 2002-11-12 Akim Demaille <akim@epita.fr>
1220
1221 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
1222 Restore.
1223 * src/scan-gram.l (last_string): Is global to the file, not to
1224 yylex.
1225 * src/parse-gram.y (input): Don't append the epilogue here,
1226 (epilogue.opt): do it here, and free the scanner's obstack.
1227 * src/reader.c (epilogue_set): Rename as...
1228 (epilogue_augment): this.
1229 * data/c.m4 (b4_epilogue): Defaults to empty.
1230
1231 2002-11-12 Akim Demaille <akim@epita.fr>
1232
1233 * src/getargs.c (long_options): Remove duplicates.

1243
1244 Use struniq for symbols.
1245
1246 * src/symtab.h (symbol_t): The tag member is a struniq.
1247 (symbol_type_set): Adjust.
1248 * src/symtab.c (symbol_new): Takes a struniq.
1249 (symbol_free): Don't free the tag member.

1271 file names.
1272 Don't free the input file name.
1273
1274 2002-11-12 Akim Demaille <akim@epita.fr>
1275
1276 * src/symtab.c (symbol_free): Remove dead deactivated code:
1277 type_name are properly removed.
1278 Don't use XFREE to free items that cannot be NULL.
1279 * src/struniq.h, src/struniq.c: New.
1280 * src/main.c (main): Initialize/free struniqs.

1287 2002-11-11 Paul Eggert <eggert@twinsun.com>
1288
1289 Revamp to fix many (but not all) of the C- and M4-related quoting
1290 problems. Among other things, this fixes the Bison bug reported
1291 by Jan Hubicka when processing the Bash grammar; see:
1292 <http://mail.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
1293
1294 Use new @ escapes consistently. Represent brackets with @{ and @}
1295 rather than @<:@ and @:>@, since this works a bit better with dumb
1296 editors like vi. Represent @ with @@, since @ is now consistently
1297 an escape. Use @oline@ and @ofile@ rather than __oline__ and
1298 __ofile__, to avoid unexpected expansions. Similarly, use @output
1299 rather than #output.
1300
1301 * data/c.m4 (b4_copyright): Omit file name from comment, since
1302 the file name could contain "*/".
1303 (b4_synclines_flag): Don't quote the 2nd argument; it should already
1304 be quoted. All uses changed.
1305
1306 * data/glr.c: Use new @ escapes consistently.
1307 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
1308 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
1309 Remove, since they couldn't handle arbitrary characters in file
1310 names.
1311 * data/lalr1.cc: Likewise.
1312 * data/yacc.c: Likewise.
1313
1314 * src/files.c (output_infix): Remove; all uses removed.
1315 * src/files.h: Likewise.
1316
1317 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
1318 mishandled funny characters in file names, and anyway it isn't
1319 needed any more.
1320 * data/yacc.c: Likewise.
1321 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
1322
1323 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
1324 * data/yacc.c: Likewise.
1325
1326 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
1327 strings now.
1328 (muscle_init): Quote filename as a C string.
1329 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
1330 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
1331 * src/output.c (escaped_file_name_output): New function.
1332 (prepare_symbols): Quote tokens for M4.
1333 (prepare): Don't insert output_infix, output_prefix,
1334 output_parser_name, output_header_name; this is now down by scan-skel.
1335 Insert skeleton as a C string.
1336
1337 * src/output.c (user_actions_output, symbol_destructors_output,
1338 symbol_printers_output): Quote filenames for C and M4.
1339 * src/reader.c (prologue_augment, epilogue_set): Likewise.
1340
1341 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
1342 escapes other than \\ and \'; this simplifies the code.
1343 (<SC_STRING>): Likewise, for \\ and \".
1344 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
1345 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
1346 Use new escapes @{ and @} for [ and ].
1347
1348 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
1349 them with auto vars.
1350 Switch to new escape scheme, where @ is the escape character uniformly.
1351 Abort if a stray escape character is found. Avoid unbounded input
1352 buffer when parsing non-escaped text.
1353
1354 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
1355 __oline__, #output, $@, and @{ do not have unintended meanings.
1356
1357 2002-11-09 Paul Eggert <eggert@twinsun.com>
1358
1359 Fix the test failure due to GCC warnings described in
1360 <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
1361 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
1362 evaluate to 0 if it's impossible for NINF to be in the respective
1363 table.
1364 (yygetLRActions, yyrecoverParseError): Use them.
1365
1366 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
1367 counted in the token inserted at end of file. Now takes
1368 location_t *, not location_t, so that the location can be
1369 adjusted. All uses changed.
1370
1371 * tests/regression.at (Invalid inputs): Adjust wording in
1372 diagnostic to match the new behavior.
1373
1374 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
1375 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
1376 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
1377 abort ();'. This reduces the runtime of the "Many lookaheads"
1378 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
1379 GCC 3.2.
1380
1381 2002-11-07 Paul Eggert <eggert@twinsun.com>
1382
1383 * src/parse-gram.y (CHARACTER): Remove unused token.
1384 All uses removed.
1385
1386 * src/scan-gram.l: Remove stack option. We no longer use the
1387 stack, since the stack was never deeper than 1; instead, use the
1388 new auto var c_context to record the stacked value.
1389
1390 Remove nounput option. At an unexpected end of file, we now unput
1391 the minimal input necessary to end cleanly; this simplifies the
1392 code.
1393
1394 Avoid unbounded token sizes where this is easy.
1395
1396 (unexpected_end_of_file): New function.
1397 Use it to systematize the error message on unexpected EOF.
1398 (last-string): Now auto, not static.
1399 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
1400 (scanner_last_string_free): Remove; not used.
1401 (percent_percent_count): Move decl to just before use.
1402 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
1403 not the (never otherwised-used) CHARACTER.
1404
1405 2002-11-07 Akim Demaille <akim@epita.fr>
1406
1407 Let yyerror always receive the msg as last argument, so that
1408 yyerror can be variadic.
1409
1410 * data/yacc.c (b4_yyerror_args): New.
1411 Use it when calling yyerror.
1412 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
1413 Use it when calling yyerror.
1414 * doc/bison.texinfo (Error Reporting): Adjust.
1415 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
1416 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
1417
1418 2002-11-06 Akim Demaille <akim@epita.fr>
1419
1420 #line should have quoted strings.
1421 Ideally, this should be done by m4_quotearg.
1422
1423 * src/scan-skel.l: Include quotearg.h.
1424 Quote __ofile__.
1425 * src/output.c (symbol_printers_output)
1426 (symbol_destructors_output): Quote the file name.
1427
1428 2002-11-06 Akim Demaille <akim@epita.fr>
1429
1430 * tests/regression.at (Invalid inputs): Adjust to the recent
1431 messages.
1432
1433 2002-11-06 Akim Demaille <akim@epita.fr>
1434
1435 Restore --no-lines.
1436 Reported by Jim Kent.
1437
1438 * data/c.m4 (b4_syncline): New.
1439 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
1440 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
1441 * src/output.c (user_actions_output): Likewise.
1442 (prepare): Define 'b4_synclines_flag'.
1443 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
1444
1445 2002-11-06 Akim Demaille <akim@epita.fr>
1446
1447 * src/main.c (main): Free `infile'.
1448 * src/scan-gram.l (handle_syncline): New.
1449 Recognize `#line'.
1450 * src/output.c (user_actions_output, symbol_destructors_output)
1451 (symbol_printers_output): Use the location's file name, not
1452 infile.
1453 * src/reader.c (prologue_augment, epilogue_set): Likewise.
1454
1455 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1456
1457 * src/tables.c (matching_state): Don't allow states to match if
1458 either has GLR conflict entries.
1459
1460 2002-11-05 Paul Eggert <eggert@twinsun.com>
1461
1462 * src/scan-gram.l: Use more accurate diagnostics, e.g.
1463 "integer out of range" rather than "invalid value".
1464 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
1465 accordingly.
1466
1467 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
1468 Also, remove one static variable in the scanner.
1469
1470 * src/scan-gram.l (braces_level): Now auto, not static.
1471 Initialize to zero if the compiler is being picky.
1472 (INITIAL): Clear braces_level instead of incrementing it.
1473 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
1474 as POSIX 1003.1-2001 requires.
1475 * src/system.h (IF_LINT): New macro, taken from coreutils.
1476 * configure.ac: Define "lint" if --enable-gcc-warnings.
1477
1478 2002-11-05 Akim Demaille <akim@epita.fr>
1479
1480 * src/scan-gram.l: When it starts with `%', complain about the
1481 whole directive, not just that `invalid character: %'.
1482
1483 2002-11-04 Akim Demaille <akim@epita.fr>
1484
1485 * Makefile.maint: Update from Autoconf.
1486 (update, cvs-update, po-update, do-po-update): New.
1487
1488 2002-11-04 Akim Demaille <akim@epita.fr>
1489
1490 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
1491 and yyerror.
1492 Have yyerror `use' its arguments.
1493 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
1494 returns true when location & yacc & pure & parse-param.
1495 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
1496
1497 2002-11-04 Akim Demaille <akim@epita.fr>
1498
1499 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
1500 clashes.
1501 * src/scan-gram.l: Use [\'] instead of ['] to pacify
1502 font-lock-mode.
1503 Use complain_at.
1504 Use quote, not quote_n since LOCATION_PRINT no longer uses the
1505 slot 0.
1506
1507 2002-11-03 Paul Eggert <eggert@twinsun.com>
1508
1509 * src/reader.c (get_merge_function, grammar_current_rule_check):
1510 Use consistent diagnostics for reporting type name clashes.
1511 Quote the types with <>, for consistency with Yacc.
1512 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
1513
1514 2002-11-03 Akim Demaille <akim@epita.fr>
1515
1516 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
1517 New.
1518 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
1519 (b4_parse_param): Remove.
1520 Use b4_identification.
1521 Propagate b4_pure_args where needed to pass them to yyerror.
1522 * data/glr.m4 (b4_parse_param): Remove.
1523 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
1524 (b4_lpure_formals): New.
1525 Use b4_identification.
1526 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
1527 b4_user_formals and b4_user_args.
1528 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
1529 (yyreportAmbiguity): When using a pure parser, also need
1530 the location, and the parse-params.
1531 Adjust callers.
1532 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
1533 When using a pure parser, also need the parse-params.
1534 Adjust callers.
1535 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
1536 (%pure-parser + %parse-param) LALR and GLR parsers.
1537 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
1538 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
1539 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
1540 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
1541 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
1542 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
1543 * doc/bison.texinfo: Untabify the whole file.
1544 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
1545 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
1546 (Error Reporting): Adjust to these new directives.
1547 Document %error-verbose, deprecate YYERROR_VERBOSE.
1548
1549 2002-11-03 Akim Demaille <akim@epita.fr>
1550
1551 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
1552 AT_CHECK_CALC_GLR invocations to use % directives, instead of
1553 command line options.
1554 * tests/cxx-type.at: Formatting changes.
1555
1556 2002-11-03 Paul Eggert <eggert@twinsun.com>
1557
1558 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
1559 to count columns correctly, and to check for invalid inputs.
1560
1561 Use mbsnwidth to count columns correctly. Account for tabs, too.
1562 Include mbswidth.h.
1563 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
1564 (extend_location): New function.
1565 (YY_LINES): Remove.
1566
1567 Handle CRLF in C code rather than in Lex code.
1568 (YY_INPUT): New macro.
1569 (no_cr_read): New function.
1570
1571 Scan UCNs, even though we don't fully handle them yet.
1572 (convert_ucn_to_byte): New function.
1573
1574 Handle backslash-newline correctly in C code.
1575 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
1576 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
1577 all uses changed.
1578 (tag, splice): New EREs. Do not allow NUL or newline in tags.
1579 Use {splice} wherever C allows backslash-newline.
1580 YY_STEP after space, newline, vertical-tab.
1581 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
1582
1583 (letter, id): Don't assume ASCII; e.g., spell out a-z.
1584
1585 ({int}, handle_action_dollar, handle_action_at): Check for integer
1586 overflow.
1587
1588 (YY_STEP): Omit trailing semicolon, so that it's more like C.
1589
1590 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
1591 as well as \000. Check for UCHAR_MAX, not 255.
1592 Allow \x with an arbitrary positive number of digits, as in C.
1593 Check for overflow here.
1594 Allow \? and UCNs, for compatibility with C.
1595
1596 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
1597 with quote slot used by complain_at.
1598
1599 * tests/input.at: Add tests for backslash-newline, m4 quotes
1600 in symbols, long literals, and funny escapes in strings.
1601
1602 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
1603 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
1604 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
1605 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
1606 * m4/mbswidth.m4: New file, from GNU coreutils.
1607
1608 * doc/bison.texinfo (Grammar Outline): Document // comments.
1609 (Symbols): Document that trigraphs have no special meaning in Bison,
1610 nor is backslash-newline allowed.
1611 (Actions): Document that trigraphs have no special meaning.
1612
1613 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
1614 no longer used.
1615
1616 2002-11-02 Paul Eggert <eggert@twinsun.com>
1617
1618 * src/reader.c: Don't include quote.h; not needed.
1619 (get_merge_function): Reword warning to be consistent with
1620 type clash diagnostic in grammar_current_rule_check.
1621
1622 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
1623 bug in trigraph handling.
1624
1625 * src/output.c (prepare_symbols): When printing token names,
1626 escape "[" as "@<:@" and likewise for "]".
1627
1628 * src/system.h (errno): Remove declaration, as we are now
1629 assuming C89 or better, and C89 guarantees errno.
1630
1631 2002-10-30 Paul Eggert <eggert@twinsun.com>
1632
1633 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
1634 Check for close failures.
1635 * src/files.h (xfclose): Return void, not int, since it always
1636 returned zero.
1637 * src/files.c (xfclose): Likewise. Report I/O error if ferror
1638 indicates one.
1639 * src/output.c (output_skeleton): Use xfclose rather than fclose
1640 and ferror. xfclose now checks ferror.
1641
1642 * data/glr.c (YYLEFTMOST_STATE): Remove.
1643 (yyreportTree): Use a stack-based leftmost state. This avoids
1644 our continuing battles with bogus warnings about initializers.
1645
1646 2002-10-30 Akim Demaille <akim@epita.fr>
1647
1648 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
1649 #if.
1650
1651 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
1652
1653 * tests/glr-regr1.at: New test for reported regressions.
1654 * tests/testsuite.at: Add glr-regr1.at test.
1655 * tests/Makefile.am: Add glr-regr1.at test.
1656
1657 2002-10-24 Paul Eggert <eggert@twinsun.com>
1658
1659 Version 1.75a.
1660
1661 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
1662 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
1663 we use malloc. Don't assume 'A' through 'Z' are contiguous.
1664 Don't assume strdup exists; POSIX says its an XSI extension.
1665 Check for buffer overflow on input.
1666
1667 2002-10-24 Akim Demaille <akim@epita.fr>
1668
1669 * src/output.c (output_skeleton): Don't disable M4sugar comments
1670 too soon: it results in comments being expanded.
1671 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
1672 first output.
1673
1674 2002-10-24 Akim Demaille <akim@epita.fr>
1675
1676 * data/yacc.c (m4_int_type): New.
1677 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
1678 char' as only yacc.c wants K&R portability.
1679 * data/glr.c (yysigned_char): Remove.
1680 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
1681 Reported by Quoc Peyrot.
1682
1683 2002-10-23 Paul Eggert <eggert@twinsun.com>
1684
1685 * src/main.c (main): With --trace=time, report times even if a
1686 non-fatal error occurs. Formerly, the times were reported in some
1687 such cases but not in others.
1688 * src/reader.c (reader): Just return if a complaint has been issued,
1689 instead of exiting, so that 'main' can report times.
1690
1691 2002-10-22 Akim Demaille <akim@epita.fr>
1692
1693 * src/system.h: Include sys/types.
1694 Reported by Bert Deknuydt.
1695
1696 2002-10-23 Paul Eggert <eggert@twinsun.com>
1697
1698 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
1699 Suggested by Art Haas.
1700
1701 2002-10-22 Paul Eggert <eggert@twinsun.com>
1702
1703 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
1704 decl; not needed any more.
1705 * src/main.c (main): Use return to exit, undoing yesterday's change.
1706 The last OS that we could find where this wouldn't work is
1707 SunOS 3.5, and that's too old to worry about now.
1708
1709 * data/glr.c (struct yyltype): Define members even when not
1710 doing locations. This is more consistent with yacc.c, and it
1711 works around the following bug reports:
1712 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
1713 http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
1714
1715 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
1716 @acronym consistently. Standardize on "Yacc" instead of "YACC",
1717 "Algol" instead of "ALGOL". Give a bit more history about BNF.
1718
1719 2002-10-22 Akim Demaille <akim@epita.fr>
1720
1721 * data/README: New.
1722
1723 2002-10-21 Paul Eggert <eggert@twinsun.com>
1724
1725 Be consistent about 'bool'; the old code used an enum in one
1726 module and an int in another, and this violates the C standard.
1727 * m4/stdbool.m4: New file, from coreutils 4.5.3.
1728 * configure.ac (AC_HEADER_STDBOOL): Add.
1729 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
1730 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
1731 * src/symtab.c (hash_compare_symbol_t): Likewise.
1732 * src/system.h (bool, false, true): Use a definition consistent
1733 with ../lib/hash.c. All uses changed.
1734
1735 * src/complain.c (warning_issued): Renamed from warn_message_count,
1736 so that we needn't worry about integer overflow (!).
1737 Now of type bool. All uses changed.
1738 (complaint_issued): Renamed from complain_message_count; likewise.
1739
1740 * src/main.c (main): Use exit to exit with failure.
1741

1749 "Try `bison --help'".
1750
1751 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
1752 What was that "2" for?
1753

1755 * src/getargs.c (usage): Likewise.
1756
1757 * src/getargs.c (getargs): When there are too few operands, report
1758 the last one. When there are too many, report the first extra
1759 one. This is how diffutils does it.

1762
1763 Remove K&R vestiges.
1764 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.

1768 fatal): Assume prototypes.
1769 * src/complain.h: Assume prototypes.
1770 * src/system.h (PARAMS): Remove.
1771 Include <limits.h> unconditionally, since it's guaranteeed even
1772 for a freestanding C89 compiler.
1773 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
1774 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.

1789 arguments and output `void'.
1790 (b4_c_function): Rename as...
1791 (b4_c_function_def): this.
1792 (b4_c_function_decl, b4_c_ansi_function_def)
1793 (b4_c_ansi_function_decl): New.
1794 Change the interpretation of the arguments: before `int, foo', now
1795 `int foo, foo'.
1796 * data/yacc.c (yyparse): Prototype and define thanks to these.
1797 Adjust b4_c_function_def uses.
1798 * data/glr.c (yyparse): Likewise, but ANSI only.

1801
1802 * src/output.c (prepare): Move the definition of `tokens_number',

1834
1835 2002-10-19 Paul Eggert <eggert@twinsun.com>
1836
1837 Do not create a temporary file, as that involves security and
1838 cleanup headaches. Instead, use a pair of pipes.
1839 Derived from a suggestion by Florian Krohm.
1840 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
1841 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
1842 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
1843 (BISON_PREREQ_SUBPIPE): Add.
1844 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.

1854 * src/scan-skel.l (readpipe): Remove decl.
1855 (scan_skel): New function, to be used in place of m4_invoke.
1856 Read from stream rather than file.
1857
1858 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
1859 float, as this generates a warning on Solaris 8 + GCC 3.2 with
1860 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
1861 this generates a more-accurate value anyway.
1862
1863 * lib/timevar.c (timervar_accumulate): Rename locals to
1864 avoid confusion with similarly-named more-global.
1865 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
1866
1867 * src/output.c (prepare): Use xstrdup to convert char const *

1871
1872 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
1873 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
1874 Use them to have `calc.y' ready for %pure-parser.
1875 * data/yacc.c (YYLEX): Pass a yylex return type to
1876 b4_c_function_call.
1877
1878 2002-10-19 Akim Demaille <akim@epita.fr>
1879
1880 Prototype support of %lex-param and %parse-param.
1881
1882 * src/parse-gram.y: Add the definition of the %lex-param and
1883 %parse-param tokens, plus their rules.
1884 Drop the `_' version of %glr-parser.
1885 Add the "," token.
1886 * src/scan-gram.l (INITIAL): Scan them.
1887 * src/muscle_tab.c: Comment changes.
1888 (muscle_insert, muscle_find): Rename `pair' as `probe'.

1893 MUSCLE_INSERT_STRING.
1894 Initialize the obstack earlier.
1895 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
1896 (muscle_pair_list_grow): New.
1897 * data/c.m4 (b4_c_function_call, b4_c_args): New.
1898 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
1899 * tests/calc.at: Use %locations, not --locations.
1900 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
1901
1902 2002-10-19 Akim Demaille <akim@epita.fr>
1903
1904 * src/getargs.c (usage): Take status as argument and exit
1905 accordingly.
1906 Report the traditional `Try ... --help' message when status != 0.
1907 (usage, version): Don't take a FILE * as arg, it is pointless.
1908 (getargs): When there is an incorrect number of arguments, make it
1909 an error, and report it GNUlically thanks to `usage ()'.
1910
1911 2002-10-18 Paul Eggert <eggert@twinsun.com>
1912
1913 * data/glr.c (yyreportParseError): Don't assume that sprintf
1914 yields the length of the printed string, as this is not true
1915 on SunOS 4.1.4. Reported by Peter Klein.
1916
1917 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
1918 * tests/conflicts.at (%nonassoc and eof): Likewise.
1919 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
1920
1921 2002-10-17 Akim Demaille <akim@epita.fr>
1922

1924 * src/getargs.c (trace_types, trace_args): Adjust.
1925 * src/reader.c (grammar_current_rule_prec_set)
1926 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
1927 Standardize error messages.
1928 And s/@prec/%prec/!
1929 (reader): Use trace_flag to enable scanner/parser debugging,
1930 instead of an adhoc scheme.
1931 * src/scan-gram.l: Remove trailing debugging code.
1932
1933 2002-10-16 Paul Eggert <eggert@twinsun.com>
1934
1935 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
1936 MUSCLE_TAB_H.
1937
1938 * NEWS: Officially drop support for building Bison with K&R C,
1939 since it didn't work anyway and it's not worth worrying about.
1940 * Makefile.maint (wget_files): Remove ansi2knr.c.
1941 (ansi2knr.c-url_prefix): Remove.
1942 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

1945
1946 2002-10-15 Paul Eggert <eggert@twinsun.com>
1947
1948 Stop using the "enum_" trick for K&R-style function definitions;
1949 it confused me, and I was the author! Instead, assume that people
1950 who want to use K&R C compilers (when using these modules in GCC,
1951 perhaps?) will run ansi2knr.
1952
1953 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
1954 All uses of "enum_" changed to "enum ".
1955 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.

1957
1958 * lib/abitset.c (abitset_and, abitset_and_cmp, abitset_and_or,

1966 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):
1967 Use function prototypes; this removes the need for declaring
1968 static functions simply to provide their prototypes.
1969 * lib/bitset.c (bitset_alloc, bitset_and_or_, bitset_and_or_cmp_,

2043 tests/cxx-type.at, tests/headers.at, tests/input.at,
2044 tests/regression.at, tests/synclines.at, tests/torture.at:
2045 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
2046 so that the tests still work even if POSIXLY_CORRECT is set.
2047 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
2048
2049 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
2050 for portability to K&R hosts. Fix typo: signed char is guaranteed
2051 only to 127, not to 128.
2052 * data/glr.c (yysigned_char): New type.
2053 * data/yacc.c (yysigned_char): Likewise.
2054 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
2055
2056 2002-10-13 Paul Eggert <eggert@twinsun.com>
2057
2058 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
2059 true due to limited range of data type" warning from GCC.
2060
2061 * data/c.m4 (b4_token_defines): Protect against double-inclusion
2062 by wrapping enum yytokentype's definition inside #ifndef
2063 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
2064
2065 2002-10-13 Akim Demaille <akim@epita.fr>
2066
2067 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
2068 Un yy- yyrhs to avoid the name clash with the global YYRHS.
2069
2070 2002-10-13 Akim Demaille <akim@epita.fr>

2081 2002-10-13 Akim Demaille <akim@epita.fr>
2082
2083 Let nondeterministic skeletons be usable with deterministic
2084 tables.
2085
2086 With the patch, GAWK compiled by GCC without -O2 passes its test
2087 suite using a GLR parser driven by LALR tables. It fails with -O2
2088 because `struct stat' gives two different answers on my machine:
2089 88 (definition of an auto var) and later 96 (memset on this var).
2090 Hence the stack is badly corrumpted. The headers inclusion is to
2091 blame: if I move the awk.h inclusion before GLR's system header
2092 inclusion, the two struct stat have the same size.
2093
2094 * src/tables.c (pack_table): Always create conflict_table.
2095 (token_actions): Always create conflict_list.
2096 * data/glr.c (YYFLAG): Remove, unused.
2097
2098 2002-10-13 Akim Demaille <akim@epita.fr>

2106 (maintainer-check-g++): New.
2107 * Makefile.am (maintainer-check): New.
2108
2109 2002-10-13 Akim Demaille <akim@epita.fr>
2110
2111 * data/glr.c: Formatting changes.
2112 Tweak some trace messages to match yacc.c's.
2113
2114 2002-10-13 Akim Demaille <akim@epita.fr>
2115
2116 GLR parsers sometimes raise parse errors instead of performing the
2117 default reduction.
2118 Reported by Charles-Henry de Boysson.
2119
2120 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
2121 check the length of the traces when %glr.
2122 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
2123 GLR's traces.
2124 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
2125 Test GLR parsers.
2126 * data/glr.c (YYLEFTMOST_STATE): Fix its value.

2128 (yytable): Complete its comment.
2129 (yygetLRActions): Map error action number from YYTABLE from
2130 YYTABLE_NINF to 0.
2131 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
2132 (which was a bug: it should have been YYTABEL_NINF, and yet it was
2133 not satisfying as we could compare an YYACTION computed from
2134 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
2135 only value for error actions.
2136 (yyreportParseError): In verbose parse error messages, don't issue
2137 `error' in the list of expected tokens.
2138 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
2139 next action to perform to match glr.c's decoding.
2140 (yytable): Complete its comment.
2141

2143
2144 Fix problem reported by Henrik Grubbstroem in
2145 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
2146 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
2147 because the Bison parser reads the second action before reducing
2148 the first one.
2149 * src/scan-gram.l (rule_length): New static var.
2150 Use it to keep track of the rule length in the scanner, since
2151 we can't expect the parser to be in lock-step sync with the scanner.
2152 (handle_action_dollar, handle_action_at): Use this var.
2153 * tests/actions.at (Exotic Dollars): Test for the problem.
2154
2155 2002-10-12 Paul Eggert <eggert@twinsun.com>
2156
2157 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
2158 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
2159 Include <sys/time.h> when checking for clock_t and struct tms.
2160 Use same include order as source.
2161 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
2162 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
2163
2164 * lib/timevar.c: Update copyright date and clarify comments.
2165 (get_time) [IN_GCC]: Keep the GCC version for reference.
2166
2167 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
2168 GCC version as of today, then merge Bison's changes.
2169 Change "GCC" to "Bison" in copyright notice. timevar.def's
2170 author is Akim, so change that too.
2171
2172 * src/reader.c (grammar_current_rule_check):
2173 Don't worry about the default action if $$ is untyped.
2174 Prevents bogus warnings reported by Jim Gifford in
2175 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
2176
2177 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
2178 * data/glr.c, data/lalr1.cc, data/yacc.c:
2179 Output token definitions before the first part of user declarations.
2180 Fixes compatibility problem reported by Jim Gifford for kbd in
2181 <http://mail.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
2182
2183 2002-10-11 Paul Eggert <eggert@twinsun.com>
2184
2185 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
2186 (yyparse): here. This undoes some of the 2002-07-25 change.
2187 Compatibility problem reported by Ralf S. Engelschall with
2188 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
2189
2190 2002-10-11 Akim Demaille <akim@epita.fr>
2191
2192 * tests/regression.at Characters Escapes): New.
2193 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Accept \' in strings and
2194 characters.
2195 Reported by Jan Nieuwenhuizen.
2196
2197 2002-10-11 Akim Demaille <akim@epita.fr>
2198
2199 * po/id.po: New.
2200
2201 2002-10-10 Paul Eggert <eggert@twinsun.com>
2202
2203 Portability fixes for bitsets; this also avoids several GCC
2204 warnings.
2205
2206 * lib/abitset.c: Include <stddef.h>, for offsetof.
2207 * lib/lbitset.c: Likewise.
2208
2209 * lib/abitset.c (abitset_bytes): Return a size that is aligned
2210 properly for vectors of objects. Do not assume that adding a
2211 header size to a multiple of a word size yields a value that is
2212 properly aligned for the whole union.
2213 * lib/bitsetv.c (bitsetv_alloc): Likewise.
2214
2215 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
2216 unique names for structures.
2217 * lib/ebitset.c (ebitset_bytes): Likewise.
2218 * lib/lbitset.c (lbitset_bytes): Likewise.
2219
2220 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
2221 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
2222 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
2223 abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
2224 abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
2225 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
2226 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
2227 to improve the type-checking that GCC can do.
2228 * lib/bitset.c (bitset_op4_cmp): Likewise.
2229 * lib/bitset_stats.c (bitset_stats_count,
2230 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
2231 bitset_stats_copy, bitset_stats_disjoint_p,
2232 bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
2233 bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
2234 bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
2235 bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
2236 bitset_stats_and_or_cmp, bitset_stats_andn_or,
2237 bitset_stats_andn_or_cmp, bitset_stats_or_and,
2238 bitset_stats_or_and_cmp): Likewise.
2239 * lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
2240 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
2241 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
2242 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
2243
2244 * lib/abitset.h: Include bitset.h, not bbitset.h.
2245 * lib/ebitset.h: Likewise.
2246 * lib/lbitset.h: Likewise.
2247
2248 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
2249 All instances of parameters of type enum bitset_opts are now of
2250 type enum_bitset_opts, to conform to the C Standard, and similarly
2251 for enum_bitset_type.
2252 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
2253 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
2254
2255 Do not use "struct bitset_struct" to mean different things in
2256 different modules. Not only is this confusing, it violates
2257 the C Standard, which requires that structure types in different
2258 modules must be compatible if one is to be passed to the other.
2259 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
2260 All instances of "struct bitset_struct *" replaced with "bitset".
2261 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
2262 (union bitset_union, struct abitset_struct, struct ebitset_struct,
2263 struct lbitset_struct, struct bitset_stats_struct): New types.
2264 All uses of struct bitset_struct changed to union bitset_union,
2265 etc.
2266 * lib/abitset.c (struct abitset_struct, abitset,
2267 struct bitset_struct): Remove.
2268 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
2269 struct bitset_struct): Remove.
2270 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
2271 bitset_struct): Remove.
2272 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
2273 Likewise.
2274
2275 Do not call a function of type T using a call that assumes the
2276 function is of a different type U. Standard C requires that a
2277 function must be called with a type that is compatible with its
2278 definition.
2279 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
2280 New decls.
2281 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
2282 New functions.
2283 * lib/ebitset.c (PFV): Remove.
2284 * lib/lbitset.c (PFV): Likewise.
2285 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
2286 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
2287 decls.
2288 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
2289 (ebitset_vtable): Use them.
2290 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
2291 lbitset_xor): New functions.
2292 (lbitset_vtable): Use them.
2293
2294 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
2295 Declare.
2296
2297 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
2298 GCC warning.
2299 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
2300 Use offsetof, for simplicity.
2301
2302 2002-10-06 Paul Eggert <eggert@twinsun.com>
2303
2304 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
2305 the same width as int. This reapplies a hunk of the 2002-08-12 patch
2306 <http://mail.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
2307 which was inadvertently undone by the 2002-09-30 patch.
2308 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
2309 the same width as int.
2310
2311 2002-10-04 Paul Eggert <eggert@twinsun.com>
2312
2313 Version 1.50.
2314
2315 * configure.ac (AC_INIT), NEWS: Increment version number.
2316
2317 * doc/bison.texinfo: Minor spelling, grammar, and white space
2318 fixes.
2319 (Symbols): Mention that any negative value returned from yylex
2320 signifies end-of-input. Warn about negative chars. Mention
2321 the portable Standard C character set.
2322
2323 The GNU coding standard says CFLAGS and YFLAGS are reserved
2324 for the installer to set.
2325 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
2326 * src/Makefile.am (AM_CFLAGS): Likewise.
2327 (AM_YFLAGS): Renamed from YFLAGS.
2328
2329 Fix some MAX and MIN problems.
2330 * src/gram.h (ITEM_NUMBER_MIN): MIN_MAX -> INT_MIN.
2331 * src/lalr.h (GOTO_NUMBER_MAX): INT_MAX -> SHRT_MAX.
2332 * src/symtab.h (SYMBOL_NUMBER_MAX): New macro.
2333 * src/reader.c (reader): Use it.
2334
2335 * tests/regression.at (Braces parsing): Use grep, not fgrep, as
2336 POSIX 1003.1-2001 has removed fgrep.
2337
2338 2002-10-04 Michael Hayes <m.hayes@elec.canterbury.ac.nz>
2339
2340 * lib/bbitset.h (BITSET_WINDEX_MAX): Redefine so that it cannot be
2341 interpreted as signed.
2342 * lib/ebitset.c (ebitset_list): Fix bug.
2343
2344 2002-10-01 Paul Eggert <eggert@twinsun.com>
2345
2346 More fixes for 64-bit hosts and large bitsets.
2347
2348 * lib/abitset.c (struct abitset_struct.n_bits, abitset_small_list,
2349 abitset_size, abitset_list, abitset_list_reverse, abitset_list):
2350 Use bitset_bindex, not int or unsigned int or size_t, to count bits.
2351 * lib/bbitset.h (struct bitset_vtable.size, struct bitset_vtable.count,
2352 struct bitset_vtable.list, struct bitset_vtable.list_reverse,
2353 bitset_count_, bitset_next, bitset_prev, bitset_first, bitset_last,
2354 bitset_count_): Likewise.

2369 Likewise.
2370
2371 * lib/abitset.c (abitset_ones, abitset_zero, abitset_bytes):
2372 Use size_t, not unsigned int, to count bytes.
2373 * lib/abitset.h (abitset_bytes): Likewise.
2374 * lib/bitset.c (bitset_bytes, bitset_alloc, bitset_obstack_alloc):
2375 Likewise.
2376 * lib/bitset.h (bitset_bytes): Likewise.
2377 * lib/bitset_stats.c (bitset_stats_bytes, bitset_stats_init): Likewise.
2378 * lib/bitset_stats.h (bitset_stats_bytes): Likewise.
2379 * lib/bitsetv.c (bitsetv_alloc): Likewise.
2380 * lib/ebitset.c (ebitset_bytes): Likewise.

2389 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
2390 abitset_or_and, abitset_or_and_cmp):
2391 Use bitset_windex instead of unsigned int.
2392 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
2393 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
2394 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,
2395 ebitset_elt_find, ebitset_list_reverse, ebitset_list, ebitset_init):
2396 Likewise.
2397 * lib/lbitset.c (lbitset_ones, lbitset_not): Likewise.

2407 * lib/bbitset.h (BITSET_BINDEX_MAX, BITSET_WINDEX_MAX,
2408 BITSET_SIZE_MAX): New macros.
2409 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
2410 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
2411 to BITSET_WINDEX_MAX.
2412
2413 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
2414 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
2415 since we now return the bitset_bindex type (not int).
2416
2417 * lib/bitsetv.c (bitsetv_alloc): Check for arithmetic overflow

2514
2515 * doc/bison.texinfo (Conditions): Make explicit that the GPL
2516 exception applies only to yacc.c. This is a modification of a
2517 patch originally suggested by Akim Demaille.
2518
2519 2002-09-06 Akim Demaille <akim@epita.fr>
2520

2531 * data/yacc.c: Guard the declaration of yytoknum also with
2532 `#ifdef YYPRINT', so it is declared only when used.
2533
2534 2002-09-04 Akim Demaille <akim@epita.fr>
2535
2536 * configure.in: Rename as...

2543 * src/lalr.c, src/LR0.c, src/relation.c, src/tables.c: Don't
2544 translate maintainer only messages.

2547
2548 Version 1.49b.
2549
2550 * Makefile.am (SUBDIRS): Remove intl.

2564 (yyreportParseError): Use size_t for yysize.
2565 (yy_yypstack): No longer nested inside yypstates, as nested
2566 functions are not portable. Do not assume size_t is the
2567 same width as int.
2568 (yypstates): Do not assume that ptrdiff_t is the same width
2569 as int, and similarly for yyposn and YYINDEX.
2570
2571 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
2572
2573 * lib/Makefile.am (INCLUDES): Do not include from the intl
2574 directory, which has been removed.
2575 * src/Makefile.am (INCLUDES): Likewise.
2576

2582 * tests/Makefile.am (EXTRA_DIST): Likewise.
2583
2584 * lib/abitset.c (abitset_reverse_list, ebitset_reverse_list):

2608 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
2609
2610 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
2611 PROTOTYPES to check for prototypes, and "defined __STDC__" to
2612 check for void *.
2613
2614 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
2615 size_t; the old version tried to do this but casted improperly.
2616 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
2617 (bitset_test): Now returns int, not unsigned long.
2618
2619 * lib/bitset_stats.c: Include "gettext.h".
2620 (_): New macro.
2621 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
2622 name locals "index", as it generates unnecessary warnings on some
2623 hosts that have an "index" function.
2624
2625 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
2626 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

2640 glibc21.m4, isc-posix.m4 lcmessage.m4, stage.m4.
2641 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.

2647 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
2648 lib/timevar.c.
2649 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
2650 manual recommends.
2651 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
2652
2653 * src/complain.c (strerror_r): Remove decl; not needed.
2654 (strerror): Use same pattern as ../lib/error.c.
2655
2656 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
2657
2658 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
2659
2660 * src/main.c (main): Cast result of bindtextdomain and textdomain
2661 to void, to avoid a GCC warning when --disable-nls is in effect.
2662
2663 * src/scan-gram.l: Use strings rather than escapes when possible,
2664 to minimize the number of warnings from xgettext.
2665 (handle_action_dollar, handle_action_at): Don't use isdigit,
2666 as it mishandles negative chars and it may not work as expected
2667 outside the C locale.
2668
2669 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
2670 this is a GCC extension and is not portable to other compilers.
2671
2672 * src/system.h (alloca): Use same pattern as ../lib/error.c.
2673 Do not include <ctype.h>; no longer needed.
2674 Do not include <malloc.h>; no longer needed (and generates
2675 warnings on OpenBSD 3.0).
2676
2677 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
2678 it's not portable.
2679
2680 * tests/regression.at: Do not use 'cc -c input.c -o input';
2681 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
2682
2683 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
2684 exit status as failure, not just exit status 1. Sun C exits
2685 with status 2 sometimes.
2686
2687 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
2688 Use it for the two large tests.
2689
2690 2002-08-02 Akim Demaille <akim@epita.fr>
2691
2692 * src/conflicts.c (conflicts_output): Don't output rules never
2693 reduced here, since anyway that computation doesn't work.
2694 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
2695 (rule_useless_p, rule_never_reduced_p): New.
2696 (grammar_rules_partial_print): Use a filter instead of a range.
2697 Display the title only if needed.

2699 (grammar_rules_never_reduced_report): New.
2700 * src/tables.c (action_row): Move the computation of rules never
2701 reduced to...
2702 (token_actions): here.
2703 * src/main.c (main): Make the parser before making the report, so
2704 that rules never reduced are computed.
2705 Call grammar_rules_never_reduced_report.
2706 * src/print.c (print_results): Report rules never reduced.
2707 * tests/conflicts.at, tests/reduce.at: Adjust.
2708
2709 2002-08-01 Akim Demaille <akim@epita.fr>
2710
2711 Instead of attaching lookaheads and duplicating the rules being
2712 reduced by a state, attach the lookaheads to the reductions.
2713
2714 * src/state.h (state_t): Remove the `lookaheads',
2715 `lookaheads_rule' member.
2716 (reductions_t): Add a `lookaheads' member.
2717 Use a regular array for the `rules'.
2718 * src/state.c (reductions_new): Initialize the lookaheads member
2719 to 0.
2720 (state_rule_lookaheads_print): Adjust.
2721 * src/state.h, src/state.c (state_reductions_find): New.

2728 (initialize_LA): this.
2729 (lalr_free): Adjust.
2730 * src/main.c (main): Don't free nullable and derives too early: it
2731 is used by --verbose.
2732 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
2733
2734 2002-08-01 Akim Demaille <akim@epita.fr>

2740 Adjust all dependencies.
2741 * src/nullable.c (set_nullable, free_nullable): Rename as...
2742 (nullable_compute, nullable_free): these.
2743 (rule_list_t): Store rule_t *, not rule_number_t.
2744 * src/state.c (state_rule_lookaheads_print): Directly compare rule
2745 pointers, instead of their numbers.
2746 * src/main.c (main): Call nullable_free, and derives_free earlier,
2747 as they were lo longer used.
2748
2749 2002-08-01 Akim Demaille <akim@epita.fr>
2750
2751 * lib/timevar.c (get_time): Include children time.
2752 * src/lalr.h (LA, LArule): Don't export them: used with the
2753 state_t.
2754 * src/lalr.c (LA, LArule): Static.
2755 * src/lalr.h, src/lalr.c (lalr_free): New.
2756 * src/main.c (main): Call it.
2757 * src/tables.c (pack_vector): Check whether loc is >= to the
2758 table_size, not >.
2759 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
2760 (tables_generate): do it, since that's also it which allocates
2761 them.
2762 Don't free LA and LArule, main does.
2763
2764 2002-07-31 Akim Demaille <akim@epita.fr>

2784 (output_check): Merge into...

2800 * src/getargs.h, src/getargs.c: Support trace_time for
2801 --trace=time.
2802 * src/main.c (stage): Remove.
2803 (main): Replace `stage' invocations with timevar calls.
2804 * src/output.c: Insert pertinent timevar calls.
2805
2806 2002-07-31 Akim Demaille <akim@epita.fr>
2807

2809
2810 * src/getargs.h (enum trace_e): New.
2811 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
2812 (long_options, short_options): --trace/-T takes an optional
2813 argument.
2814 Change all the uses of trace_flag to reflect the new flags.
2815 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
2816

2827
2828 In verbose parse error message, don't report `error' as an
2829 expected token.
2830 * tests/actions.at (Printers and Destructors): Adjust.
2831 * tests/calc.at (Calculator $1): Adjust.
2832 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
2833 error message, do not report the parser accepts the error token in
2834 that state.
2835
2836 2002-07-30 Akim Demaille <akim@epita.fr>
2837

2849 by conflicts.
2850
2851 * src/LR0.c (save_reductions): Don't make the final state too
2852 different: save its reduction (accept) instead of having a state
2853 without any action (no shift or goto, no reduce).
2854 Note: the final state is now a ``regular'' state, i.e., the
2855 parsers now contain `reduce 0' as default reduction.
2856 Nevertheless, since they decide to `accept' when yystate =
2857 final_state, they still will not reduce rule 0.
2858 * src/print.c (print_actions, print_reduction): Adjust.
2859 * src/output.c (action_row): Track reduced rules.
2860 (token_actions): Report rules never reduced.

2873
2874 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not

2882 2002-07-29 Akim Demaille <akim@epita.fr>
2883

2885
2886 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
2887 (endtoken, accept): these.
2888 * src/reader.c (reader): Set endtoken's default tag to "$end".
2889 Set undeftoken's tag to "$undefined" instead of "$undefined.".
2890 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
2891 Adjust.
2892
2893 2002-07-29 Akim Demaille <akim@epita.fr>
2894
2895 * src/reduce.c (reduce_grammar): When the language is empty,
2896 complain about the start symbol, not the axiom.
2897 Use its location.
2898 * tests/reduce.at (Empty Language): New.
2899
2900 2002-07-26 Akim Demaille <akim@epita.fr>
2901
2902 * src/reader.h, src/reader.c (gram_error): ... can't get
2903 yycontrol without making too strong assumptions on the parser
2904 itself.
2905 * src/output.c (prepare_tokens): Use the real 0th value of
2906 token_translations instead of `0'.
2907 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
2908 visible here.
2909 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
2910 for the time being: %locations ought to provide it to yyerror.
2911
2912 2002-07-25 Akim Demaille <akim@epita.fr>
2913
2914 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
2915 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
2916 * tests/regression.at (Web2c Actions): Adjust.
2917
2918 2002-07-25 Akim Demaille <akim@epita.fr>

2923 * src/nullable.c, src/output.c, src/print.c, src/reader.c
2924 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
2925 Iterate from 0 to nrules.
2926 Use rule_number_as_item_number and item_number_as_rule_number.
2927 Adjust to `derive' now containing possibly 0.
2928 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
2929 Handle the `- 1' part in rule numbers from/to item numbers.
2930 * src/conflicts.c (log_resolution): Fix the message which reversed
2931 shift and reduce.
2932 * src/output.c (action_row): Initialize default_rule to -1.

4059 assigning twice the same user number to a token, so that we can
4060 use it in...
4061 * src/lex.c (lex): here.
4062 Also use `symbol_class_set' instead of hand written code.
4063 * src/reader.c (parse_assoc_decl): Likewise.

4072
4073 2002-06-10 Akim Demaille <akim@epita.fr>
4074
4075 Remove `%thong' support as it is undocumented, unused, duplicates
4076 `%token's job, and creates useless e-mail traffic with people who
4077 want to know what it is, why it is undocumented, unused, and
4078 duplicates `%token's job.
4079
4080 * src/reader.c (parse_thong_decl): Remove.

4146
4147 2002-05-27 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
4148
4149 * src/output.c (output_skeleton): Put an explicit path in front of
4150 the skeleton file name, rather than relying on the -I directory,
4151 to partially alleviate effects of having a skeleton file lying around

4155
4156 * src/conflicts.c (log_resolution): Correct typo:

4223 and Paul Eggert <eggert@twinsun.com>
4224
4225 * data/bison.simple (yyparse): Correct error handling to conform to

4233
4234 * data/bison.simple (yyr1): Don't use yy_token_number_type as element

4451 Adjust callers.
4452 (copy_at, copy_dollar): Instead of outputting the hard coded
4453 values of $$, $n and so forth, output invocation to b4_lhs_value,
4454 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
4455 Note: this patch partially drops `semantic-parser' support: it
4456 always does `rule_length - n', where semantic parsers ought to
4457 always use `-n'.

4562 2002-04-22 Akim Demaille <akim@epita.fr>
4563
4564 * src/reader.c (token_translations_init): 256 is now the default
4565 value for the error token, i.e., it will be assigned another
4566 number if the user assigned 256 to one of her tokens.

4568 * doc/bison.texinfo (Symbols): Adjust.
4569 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
4570 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
4571 etc. instead of 10, 20, 30 (which was used to `jump' over error

4609 2002-04-09 Akim Demaille <akim@epita.fr>
4610
4611 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
4612 full stderr, and strip it according to the bison options, instead
4613 of composing the error message from different bits.
4614 This makes it easier to check for several error messages.
4615 Adjust all the invocations.
4616 Add an invocation exercising the error token.
4617 Add an invocation demonstrating a stupid error message.
4618 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

4629 * src/symtab.h: here.
4630 (state_t.number): Is a token_number_t.
4631 * src/print.c, src/reader.c: Use undeftoken->number instead of
4632 hard coded 2.
4633 (Even though this 2 is not the same as above: the number of the
4634 undeftoken remains being 2, it is its user token number which
4635 might not be 2).
4636 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
4637 `user_token_number_max'.
4638 Output `undef_token_number'.
4639 * data/bison.simple, data/bison.c++: Use them.
4640 Be sure to map invalid yylex return values to
4641 `undef_token_number'. This saves us from gratuitous SEGV.

4658
4659 * src/gram.h (item_number_t): New, the type of item numbers in
4660 RITEM. Note that it must be able to code symbol numbers as
4661 positive number, and the negation of rule numbers as negative
4662 numbers.
4663 Adjust all dependencies (pretty many).
4664 * src/reduce.c (rule): Remove this `short *' pointer: use
4665 item_number_t.
4666 * src/system.h (MINSHORT, MAXSHORT): Remove.
4667 Include `limits.h'.
4668 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

4674 * tests/torture.at (Big triangle): Move the limit from 254 to
4675 500.
4676 * tests/regression.at (Web2c Actions): Ajust.
4677
4678 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
4679 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
4680 passes, but produces negative #line number, once fixed, GCC is
4681 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
4682 C), it passes.
4683 * src/state.h (state_h): Code input lines on ints, not shorts.
4684
4685 2002-04-08 Akim Demaille <akim@epita.fr>
4686
4687 * src/reduce.c (reduce_grammar): First reduce the nonterminals,
4688 and then the grammar.
4689

4699 * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
4700 New.
4701 Use them to define yy_token_number_type/TokenNumberType.
4702 Use this type for yytranslate.

4704 253.

5149
5150 2002-02-25 Akim Demaille <akim@epita.fr>
5151
5152 * src/getargs.c (version): Give the name of the authors, and use a
5153 translator friendly scheme for the bgr
5154 copyright notice.
5155
5156 2002-02-25 Akim Demaille <akim@epita.fr>
5157
5158 * src/output.c (header_output): Remove, now handled completely via
5159 M4.
5160
5161 2002-02-25 Akim Demaille <akim@epita.fr>
5162
5163 * m4/m4.m4: New, from CVS Autoconf.
5164 * configure.in: Invoke it.
5165 * src/output.c (output_skeleton): Use its result instead of the
5166 hard coded name.
5167
5168 2002-02-25 Akim Demaille <akim@epita.fr>
5169
5170 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
5171 Fileutils 4.1.5.
5172 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
5173 * src/output.c (output_skeleton): Use mkstemp to create a real
5174 temporary file.
5175 Move the filling of `skeleton' and its muscle to...
5176 (prepare): here.
5177 (output): Move the definition of the prologue muscle to...
5178 (prepare): here.
5179 * src/system.h (DEFAULT_TMPDIR): New.
5180
5181 2002-02-14 Paul Eggert <eggert@twinsun.com>
5182
5183 Remove the support for C++ namespace cleanliness; it was
5184 causing more problems than it was curing, since it didn't work
5185 properly on some nonstandard C++ compilers. This can wait
5186 for a proper C++ parser.
5187
5188 * NEWS: Document this.
5189 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
5190 of C++, as it's treated like C now.
5191 * src/bison.simple (YYSTD): Remove.
5192 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
5193 Treat C++ just like Standard C instead of trying to support
5194 namespace cleanliness.
5195
5196 2002-02-14 Akim Demaille <akim@epita.fr>
5197
5198 * tests/regression.at (else): Adjust to Andreas' change.
5199
5200 2002-02-14 Akim Demaille <akim@epita.fr>
5201
5202 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
5203
5204 2002-02-13 Andreas Schwab <schwab@suse.de>
5205
5206 * src/output.c (output_rule_data): Don't output NULL, it might
5207 not be defined yet.
5208
5209 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
5210
5211 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
5212 (Copyright notice): Update.
5213
5214 2002-02-11 Akim Demaille <akim@epita.fr>
5215
5216 * tests/regression.at (%nonassoc and eof): Don't include
5217 nonportable headers.
5218
5219 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
5220
5221 * data/bison.c++: Correct error recovery. Make the user able to
5222 initialize the starting location.
5223
5224 2002-02-07 Akim Demaille <akim@epita.fr>
5225
5226 * tests/input.at: New.
5227
5228 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
5229
5230 * data/bison.c++: Replace some direct m4 expansions by constants. Be
5231 more consistent when naming methods and variables. Put preprocessor
5232 directives around tables only needed for debugging.
5233
5234 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
5235
5236 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
5237 C++ parsers.
5238 (yy::b4_name::parse): Use print_.
5239
5240 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
5241
5242 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
5243
5244 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
5245
5246 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
5247 C++ parsers.
5248 (yy::b4_name::parse): Build verbose error messages, and use error_.
5249
5250 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
5251
5252 * data/bison.c++: Fix m4 quoting in comments.
5253
5254 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
5255
5256 * data/bison.c++: Adjust the parser code. Fix some muscles that were
5257 not expanded by m4.
5258
5259 2002-02-05 Akim Demaille <akim@epita.fr>
5260
5261 * data/bison.c++: Adjust to the M4 back end.
5262 More is certainly needed.
5263
5264 2002-02-05 Akim Demaille <akim@epita.fr>
5265
5266 Give a try to M4 as a back end.
5267
5268 * lib/readpipe.c: New, from wdiff.
5269 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
5270 BISON_HAIRY.
5271 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
5272 specific values. Now it is m4 that performs the lookup.
5273 * src/parse-skel.y: Remove.
5274 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
5275 * src/output.c (actions_output, guards_output)
5276 (token_definitions_output): No longer keeps track of the output
5277 line number, hence remove the second argument.
5278 (guards_output): Check against the guard member of a rule, not the
5279 action member.
5280 Adjust callers.
5281 (output_skeleton): Don't look for the skeleton location, let m4 do
5282 that.
5283 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
5284 file will be used.
5285 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
5286 (prepare): Given that for the time being changesyntax is not
5287 usable in M4, rename the muscles using `-' to `_'.
5288 Define `defines_flag', `output_parser_name' and `output_header_name'.
5289 * src/output.h (actions_output, guards_output)
5290 (token_definitions_output): Adjust prototypes.
5291 * src/scan-skel.l: Instead of scanning the skeletons, it now
5292 processes the output of m4: `__oline__' and `#output'.
5293 * data/bison.simple: Adjust to be used by M4(sugar).
5294 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
5295 to date.
5296 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
5297 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
5298 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
5299 shamelessly stolen from CVS Autoconf.
5300
5301 2002-02-05 Akim Demaille <akim@epita.fr>
5302
5303 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
5304 * configure.in: Check for the declarations of free and malloc.
5305 * src/muscle_tab.c: Adjust.
5306
5307 2002-02-05 Akim Demaille <akim@epita.fr>
5308
5309 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
5310 which have no values.
5311
5312 2002-02-05 Akim Demaille <akim@epita.fr>
5313
5314 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
5315 * data/: here.
5316
5317 2002-01-29 Paul Eggert <eggert@twinsun.com>
5318
5319 * src/bison.simple (YYSIZE_T): Do not define merely because
5320 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
5321 On some platforms, <alloca.h> does not declare YYSTD (size_t).
5322
5323 2002-01-27 Akim Demaille <akim@epita.fr>
5324
5325 Fix `%nonassoc and eof'.
5326
5327 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
5328 which were not properly copied! Replace
5329 memcpy (res->errs, src->errs, src->nerrs);
5330 with
5331 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
5332 !!!
5333 * tests/regression.at (%nonassoc and eof): Adjust to newest
5334 Autotest: `.' is not in the PATH.
5335
5336 2002-01-27 Akim Demaille <akim@epita.fr>
5337
5338 * tests/sets.at (AT_EXTRACT_SETS): New.
5339 (Nullable): Use it.
5340 (Firsts): New.
5341
5342 2002-01-26 Akim Demaille <akim@epita.fr>
5343
5344 * tests/actions.at, tests/calc.at, tests/headers.at,
5345 * tests/torture.at: Adjust to the newest Autotest which no longer
5346 forces `.' in the PATH.
5347
5348 2002-01-25 Akim Demaille <akim@epita.fr>
5349
5350 * tests/regression.at (%nonassoc and eof): New.
5351 Suggested by Robert Anisko.
5352
5353 2002-01-24 Akim Demaille <akim@epita.fr>
5354
5355 Bison dumps core when trying to complain about broken input files.
5356 Reported by Cris van Pelt.
5357
5358 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
5359 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
5360 into...
5361 (Invalid inputs): Strengthen: exercise parse_percent_token.
5362
5363 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
5364
5365 * src/Makefile.am: Add bison.c++.
5366 * src/bison.c++: New skeleton.
5367
5368 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
5369
5370 * po/it.po: New.
5371
5372 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
5373
5374 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
5375
5376 2002-01-20 Marc Autret <marc@gnu.org>
5377
5378 * src/files.c (compute_output_file_names): Fix
5379
5380 2002-01-20 Marc Autret <marc@gnu.org>
5381
5382 * tests/output.at: New test.
5383 * src/files.c (compute_base_names): Don't map extensions when
5384 the YACC flag is set, use defaults.
5385 Reported by Evgeny Stambulchik.
5386
5387 2002-01-20 Marc Autret <marc@gnu.org>
5388
5389 * src/system.h: Need to define __attribute__ away for non-GCC
5390 compilers as well (i.e. the vendor C compiler).
5391 Suggested by Albert Chin-A-Young.
5392
5393 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
5394
5395 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
5396 canonical definition.
5397 * src/system.h: Use the canonical definition for PARAMS (avoids
5398 a conflict with the macro from lib/hash.h).
5399
5400 2002-01-11 Akim Demaille <akim@epita.fr>
5401
5402 * configure.in: Use AC_FUNC_STRNLEN.
5403 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
5404
5405 2002-01-09 Akim Demaille <akim@epita.fr>
5406
5407 * src/files.c, src/files.h (output_infix): New.
5408 (tab_extension): Remove.
5409 (compute_base_names): Compute the former, drop the latter.
5410 * src/output.c (prepare): Insert the muscles `output-infix', and
5411 `output-suffix'.
5412 * src/parse-skel.y (string, string.1): New.
5413 (section.header): Use it.
5414 (section.yacc): Remove.
5415 (prefix): Remove too.
5416 * src/scan-skel.l: Adjust.
5417 * src/bison.simple, src/bison.hairy: Adjust.
5418
5419 2002-01-09 Akim Demaille <akim@epita.fr>
5420
5421 * configure.in (WERROR_CFLAGS): Compute it.
5422 * src/Makefile.am (CFLAGS): Pass it.
5423 * tests/atlocal.in (CFLAGS): Idem.
5424 * src/files.c: Fix a few warnings.
5425 (get_extension_index): Remove, unused.
5426
5427 2002-01-08 Akim Demaille <akim@epita.fr>
5428
5429 * src/getargs.c (AS_FILE_NAME): New.
5430 (getargs): Use it to convert DOSish file names.
5431 * src/files.c (base_name): Rename as full_base_name to avoid
5432 clashes with `base_name ()'.
5433 (filename_split): New.
5434 (compute_base_names): N-th rewrite, using filename_split.
5435
5436 2002-01-08 Akim Demaille <akim@epita.fr>
5437
5438 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
5439 New, stolen from the Fileutils 4.1.
5440 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
5441 * configure.in: Check for the presence of memrchr, and of its
5442 prototype.
5443
5444 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
5445
5446 * lib/hash.h (__P): Added definition for this macro.
5447 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
5448 BUILT_SOURCES, to ensure they are generated first.
5449 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
5450 %error-verbose to allow bootstrapping with bison 1.30x.
5451
5452 2002-01-06 Akim Demaille <akim@epita.fr>
5453
5454 * src/reader.c (parse_braces): Don't fetch the next char, the
5455 convention is to fetch on entry.
5456 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
5457 'switch' without a following semicolon.
5458 * tests/regression.at (braces parsing): New.
5459
5460 2002-01-06 Akim Demaille <akim@epita.fr>
5461
5462 Bison is dead wrong in its RR conflict reports.
5463
5464 * tests/torture.at (GNU Cim Grammar): New.
5465 * src/conflicts.c (count_rr_conflicts): Fix.
5466
5467 2002-01-06 Akim Demaille <akim@epita.fr>
5468
5469 Creating package.m4 from configure.ac causes too many problems.
5470
5471 * tests/Makefile.am (package.m4): Create it by hand,
5472 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
5473
5474 2002-01-06 Akim Demaille <akim@epita.fr>
5475
5476 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
5477 skeleton.h.
5478
5479 2002-01-04 Paul Eggert <eggert@twinsun.com>
5480
5481 * doc/bison.texinfo (Debugging):
5482 Remove YYSTDERR; it's no longer defined or used.
5483 Also, s/cstdio.h/cstdio/.
5484
5485 2002-01-03 Akim Demaille <akim@epita.fr>
5486
5487 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
5488
5489 2002-01-03 Akim Demaille <akim@epita.fr>
5490
5491 * src/parse-skel.y (process_skeleton): Don't bind the parser's
5492 tracing code to --trace, wait for a better --trace option, with
5493 args.
5494
5495 2002-01-03 Akim Demaille <akim@epita.fr>
5496
5497 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
5498 The ISO C++ standard is extremely clear about it: stderr is
5499 considered a macro, not a regular symbol (see table 94 `Header
5500 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
5501 Therefore std:: does not apply to it. It still does with fprintf.
5502 Also, s/cstdio.h/cstdio/.
5503
5504 2002-01-03 Akim Demaille <akim@epita.fr>
5505
5506 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
5507 for non system headers.
5508
5509 2002-01-02 Akim Demaille <akim@epita.fr>
5510
5511 Equip the skeleton chain with location tracking, runtime trace,
5512 pure parser and scanner.
5513
5514 * src/parse-skel.y: Request a pure parser, locations, and prefix
5515 renaming.
5516 (%union): Having several members with the same type does not help
5517 type mismatches, simplify.
5518 (YYPRINT, yyprint): New.
5519 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
5520 (skel_error): this.
5521 Handle locations.
5522 * src/scan-skel.l: Adjust to these changes.
5523 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
5524 (LOCATION_PRINT, skel_control_t): New.
5525
5526 2001-12-30 Akim Demaille <akim@epita.fr>
5527
5528 * src/parse-skel.y: Get rid of the shift/reduce conflict:
5529 replace `gb' with BLANKS.
5530 * src/scan-skel.l: Adjust.
5531
5532 2001-12-30 Akim Demaille <akim@epita.fr>
5533
5534 * src/system.h: We don't need nor want bcopy.
5535 Throw away MS-DOS crap: we don't need getpid.
5536 * configure.in: We don't need strndup. It was even causing
5537 problems: because Flex includes the headers *before* us,
5538 _GNU_SOURCE is not defined by config.h, and therefore strndup was
5539 not visible.
5540 * lib/xstrndup.c: New.
5541 * src/scan-skel.l: Use it.
5542 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
5543 * src/parse-skel.y: Use %directives instead of #defines.
5544
5545 2001-12-30 Akim Demaille <akim@epita.fr>
5546
5547 * src/skeleton.h: New.
5548 * src/output.c (output_parser, output_master_parser): Remove, dead
5549 code.
5550 * src/output.h (get_lines_number, actions_output, guards_output)
5551 (token_definitions_output): Prototype them.
5552 * src/parse-skel.y: Add the license notice.
5553 Include output.h and skeleton.h.
5554 (process_skeleton): Returns void, and takes a single parameter.
5555 * src/scan-skel.l: Add the license notice.
5556 Include skeleton.h.
5557 Don't use %option yylineno: it seems that then Flex imagines
5558 REJECT has been used, and therefore it won't reallocate its
5559 buffers (which makes no other sense to me than a bug). It results
5560 in warnings for `unused: yy_flex_realloc'.
5561
5562 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
5563
5564 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
5565 (MUSCLE_INSERT_PREFIX): ...to there.
5566 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
5567 (MUSCLE_INSERT_PREFIX): Move from here...
5568
5569 * src/bison.hairy: Add a section directive. Put braces around muscle
5570 names. This parser skeleton is still broken, but Bison should not
5571 choke on a bad muscle 'syntax'.
5572 * src/bison.simple: Add a section directive. Put braces around muscle
5573 names.
5574
5575 * src/files.h (strsuffix, stringappend): Add declarations.
5576 (tab_extension): Add declaration.
5577 (short_base_name): Add declaration.
5578
5579 * src/files.c (strsuffix, stringappend): No longer static. These
5580 functions are used in the skeleton parser.
5581 (tab_extension): New.
5582 (compute_base_names): Use the computations done in this function
5583 to guess if the generated parsers should have '.tab' in their
5584 names.
5585 (short_base_name): No longer static.
5586
5587 * src/output.c (output_skeleton): New.
5588 (output): Disable call to output_master_parser, and give a try to
5589 a new skeleton handling system.
5590 (guards_output, actions_output): No longer static.
5591 (token_definitions_output, get_lines_number): No longer static.
5592
5593 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
5594
5595 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
5596 parse-skel.y.
5597
5598 * src/parse-skel.y: New file.
5599 * src/scan-skel.l: New file.
5600
5601 2001-12-29 Akim Demaille <akim@epita.fr>
5602
5603 %name-prefix is broken.
5604
5605 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
5606 Adjust all dependencies.
5607 * tests/headers.at (export YYLTYPE): Strengthen this test: use
5608 %name-prefix.
5609
5610 Renaming yylval but not yylloc is not consistent. Now we do.
5611
5612 * src/bison.simple: Prefix yylloc if used.
5613 * doc/bison.texinfo (Decl Summary): Document that.
5614
5615 2001-12-29 Akim Demaille <akim@epita.fr>
5616
5617 * doc/bison.texinfo: Promote `%long-directive' over
5618 `%long_directive'.
5619 Remove all references to fixed-output-files, yacc is enough.
5620
5621 2001-12-29 Akim Demaille <akim@epita.fr>
5622
5623 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
5624 user prologue. These are defaults.
5625 * tests/actions.at (Mid-rule actions): Make sure the user can
5626 define YYDEBUG and YYERROR_VERBOSE.
5627
5628 2001-12-29 Akim Demaille <akim@epita.fr>
5629
5630 * src/output.c (header_output): Don't forget to export YYLTYPE and
5631 yylloc.
5632 * tests/headers.at (export YYLTYPE): New, make sure it does.
5633 * tests/regression.at (%union and --defines, Invalid CPP headers):
5634 Move to...
5635 * tests/headers.at: here.
5636
5637 2001-12-29 Akim Demaille <akim@epita.fr>
5638
5639 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
5640
5641 2001-12-29 Akim Demaille <akim@epita.fr>
5642
5643 * tests/actions.at (Mid-rule actions): Output on a single line
5644 instead of several.
5645
5646 2001-12-29 Akim Demaille <akim@epita.fr>
5647
5648 * doc/bison.texinfo: Formatting changes.
5649
5650 2001-12-29 Akim Demaille <akim@epita.fr>
5651
5652 Don't store the token defs in a muscle, just be ready to output it
5653 on command. Now possible via `symbols'. Fixes a memory leak.
5654
5655 * src/output.c (token_definitions_output): New.
5656 (output_parser, header_output): Use it.
5657 * src/reader.c (symbols_save): Remove.
5658
5659 2001-12-29 Akim Demaille <akim@epita.fr>
5660
5661 * src/bison.simple: Do not provide a default for YYSTYPE and
5662 YYLTYPE before the user's prologue. Otherwise it's hardly... a
5663 default.
5664
5665 2001-12-29 Akim Demaille <akim@epita.fr>
5666
5667 Mid-rule actions are simply... ignored!
5668
5669 * src/reader.c (readgram): Be sure to attach mid-rule actions to
5670 the empty-rule associated to the dummy symbol, not to the host
5671 rule.
5672 * tests/actions.at (Mid-rule actions): New.
5673
5674 2001-12-29 Akim Demaille <akim@epita.fr>
5675
5676 Memory leak.
5677
5678 * src/reader.c (reader): Free grammar.
5679
5680 2001-12-29 Akim Demaille <akim@epita.fr>
5681
5682 Memory leak.
5683
5684 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
5685 since it allocates it for each state, although only one is needed.
5686 (allocate_storage): Do it here.
5687
5688 2001-12-29 Akim Demaille <akim@epita.fr>
5689
5690 * src/options.h, src/options.c (create_long_option_table): Rename
5691 as...
5692 (long_option_table_new): this, with a clearer prototype.
5693 (percent_table): Remove, unused,
5694 * src/getargs.c (getargs): Adjust.
5695
5696 2001-12-29 Akim Demaille <akim@epita.fr>
5697
5698 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
5699 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
5700 as states.
5701
5702 2001-12-29 Akim Demaille <akim@epita.fr>
5703
5704 * src/lalr.c (build_relations): Rename `states' as `states1'.
5705 Sorry, I don't understand exactly what it is, no better name...
5706
5707 2001-12-29 Akim Demaille <akim@epita.fr>
5708
5709 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
5710 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
5711 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
5712 as rules.
5713
5714 2001-12-29 Akim Demaille <akim@epita.fr>
5715
5716 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
5717 ago.
5718
5719 2001-12-29 Akim Demaille <akim@epita.fr>
5720
5721 * src/reader.c, src/reader.h (user_toknums): Remove.
5722 Adjust all users to use symbols[i]->user_token_number.
5723
5724 2001-12-29 Akim Demaille <akim@epita.fr>
5725
5726 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
5727 Adjust all users to use symbols[i]->prec or ->assoc.
5728
5729 2001-12-29 Akim Demaille <akim@epita.fr>
5730
5731 * src/reader.c, src/reader.h (tags): Remove.
5732 Adjust all users to use symbols[i]->tag.
5733
5734 2001-12-29 Akim Demaille <akim@epita.fr>
5735
5736 * src/gram.h, src/gram.c (symbols): New, similar to state_table
5737 and rule_table.
5738 * src/reader.c (packsymbols): Fill this table.
5739 Drop sprec.
5740 * src/conflicts.c (resolve_sr_conflict): Adjust.
5741 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
5742 single table.
5743 Use symbols[i]->tag instead of tags[i].
5744
5745 2001-12-29 Akim Demaille <akim@epita.fr>
5746
5747 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
5748 In addition, put a comment in there, to replace...
5749 * tests/regression.at (%union and C comments): Remove.
5750
5751 2001-12-29 Akim Demaille <akim@epita.fr>
5752
5753 * tests/regression.at (Web2c Actions): Blindly move the actual
5754 output as expected output. The contents *seem* right to me, but I
5755 can't pretend reading perfectly parser tables... Nonetheless, all
5756 the other tests pass correctly, the table look OK, even though the
5757 presence of `$axiom' is to be noted: AFAICS it is useless (but
5758 harmless).
5759
5760 2001-12-29 Akim Demaille <akim@epita.fr>
5761
5762 * src/reader.c (readgram): Don't add the rule 0 if there were no
5763 rules read. In other words, add it _after_ having performed
5764 grammar sanity checks.
5765 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
5766
5767 2001-12-29 Akim Demaille <akim@epita.fr>
5768
5769 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
5770 visible, and some states have now a different number.
5771
5772 2001-12-29 Akim Demaille <akim@epita.fr>
5773
5774 * src/reader.c (readgram): Bind the initial rule's lineno to that
5775 of the first rule.
5776 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
5777 (Solved SR Conflicts): Adjust rule 0's line number.
5778
5779 2001-12-29 Akim Demaille <akim@epita.fr>
5780
5781 Fix the `GAWK Grammar' failure.
5782
5783 * src/LR0.c (final_state): Initialize to -1 so that we do compute
5784 the reductions of the first state which was mistakenly confused
5785 with the final state because precisely final_state was initialized
5786 to 0.
5787 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
5788 now noticed by Bison.
5789 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
5790 have a reduction on $default.
5791
5792 2001-12-29 Akim Demaille <akim@epita.fr>
5793
5794 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
5795 rule line numbers.
5796 * src/closure.c (print_closure): Likewise.
5797 * src/derives.c (print_derives): Likewise.
5798 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
5799 now.
5800
5801 2001-12-29 Akim Demaille <akim@epita.fr>
5802
5803 * src/lalr.c (lookaheads_print): New.
5804 (lalr): Call it when --trace-flag.
5805 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
5806 are dumped.
5807
5808 2001-12-29 Akim Demaille <akim@epita.fr>
5809
5810 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
5811 when walking through ritem, even via rule->rhs.
5812 * src/reduce.c (dump_grammar, useful_production, reduce_output)
5813 (useful_production, useless_nonterminals): Likewise.
5814 (reduce_grammar_tables): Likewise, plus update nritems.
5815 * src/nullable.c (set_nullable): Likewise.
5816 * src/lalr.c (build_relations): Likewise.
5817 * tests/sets.at (Nullable): Adjust.
5818 Fortunately, now, the $axiom is no longer nullable.
5819
5820 2001-12-29 Akim Demaille <akim@epita.fr>
5821
5822 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
5823 the 0-sentinel.
5824 * src/gram.c (ritem_longest_rhs): Likewise.
5825 * src/reduce.c (nonterminals_reduce): Likewise.
5826 * src/print_graph.c (print_graph): Likewise.
5827 * src/output.c (output_rule_data): Likewise.
5828 * src/nullable.c (set_nullable): Likewise.
5829
5830 2001-12-29 Akim Demaille <akim@epita.fr>
5831
5832 * src/output.c: Comment changes.
5833
5834 2001-12-27 Paul Eggert <eggert@twinsun.com>
5835
5836 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
5837 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
5838 Sparc, as they were causing more porting problems than the
5839 (minor) performance improvement was worth.
5840
5841 Also, catch up with 1.31's YYSTD.
5842
5843 2001-12-27 Akim Demaille <akim@epita.fr>
5844
5845 * src/output.c (output_gram): Rely on nritems, not the
5846 0-sentinel. See below.
5847 Use -1 as separator, not 0.
5848 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
5849 Rely on -1 as separator in yyrhs, instead of 0.
5850 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
5851 twice `Now at end of input', therefore there are two lines less to
5852 expect.
5853
5854 2001-12-27 Akim Demaille <akim@epita.fr>
5855
5856 * tests/regression.at (Unresolved SR Conflicts):
5857 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
5858 below.
5859
5860 2001-12-27 Akim Demaille <akim@epita.fr>
5861
5862 * src/LR0.c (new_state): Recognize the final state by the fact it
5863 is reached by eoftoken.
5864 (insert_start_shifting_state, insert_eof_shifting_state)
5865 (insert_accepting_state, augment_automaton): Remove, since now
5866 these states are automatically computed from the initial state.
5867 (generate_states): Adjust.
5868 * src/print.c: When reporting a rule number to the user, substract
5869 1, so that the axiom rule is rule 0, and the first user rule is 1.
5870 * src/reduce.c: Likewise.
5871 * src/print_graph.c (print_core): For the time being, just as for
5872 the report, depend upon --trace-flags to dump the full set of
5873 items.
5874 * src/reader.c (readgram): Once the grammar read, insert the rule
5875 0: `$axiom: START-SYMBOL $'.
5876 * tests/set.at: Adjust: rule 0 is now displayed, and since the
5877 number of the states has changed (the final state is no longer
5878 necessarily the last), catch up.
5879
5880 2001-12-27 Akim Demaille <akim@epita.fr>
5881
5882 Try to make the use of the eoftoken valid. Given that its value
5883 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
5884 is used instead of > 0 where appropriate, (ii), depend upon nritems
5885 instead of the 0-sentinel.
5886
5887 * src/gram.h, src/gram.c (nritems): New.
5888 Expected to be duplication of nitems, but for the time being...
5889 * src/reader.c (packgram): Assert nritems and nitems are equal.
5890 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
5891 * src/closure.c (print_closure, print_fderives): Likewise.
5892 * src/gram.c (ritem_print): Likewise.
5893 * src/print.c (print_core, print_grammar): Likewise.
5894 * src/print_graph.c: Likewise.
5895
5896 2001-12-27 Akim Demaille <akim@epita.fr>
5897
5898 * src/main.c (main): If there are complains after grammar
5899 reductions, then output the report anyway if requested, then die.
5900 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
5901 * src/reader.c (eoftoken): New.
5902 (parse_token_decl): If the token being defined has value `0', it
5903 is the eoftoken.
5904 (packsymbols): No longer hack `tags' to insert `$' by hand.
5905 Be sure to preserve the value of the eoftoken.
5906 (reader): Make sure eoftoken is defined.
5907 Initialize nsyms to 0: now eoftoken is created just like the others.
5908 * src/print.c (print_grammar): Don't special case the eof token.
5909 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
5910 lie anyway, albeit pleasant.
5911 * tests/calc.at: Exercise error messages with eoftoken.
5912 Change the grammar so that empty input is invalid.
5913 Adjust expectations.
5914 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
5915
5916 2001-12-27 Akim Demaille <akim@epita.fr>
5917
5918 * configure.in: Check the protos of strchr ans strspn.
5919 Replace strchr if needed.
5920 * src/system.h: Provide the protos of strchr, strspn and memchr if
5921 missing.
5922 * lib/strchr.c: New.
5923 * src/reader.c (symbols_save): Use strchr.
5924
5925 2001-12-27 Akim Demaille <akim@epita.fr>
5926
5927 * src/print.c, src/print_graph.c (escape): New.
5928 Use it to quote the TAGS outputs.
5929 * src/print_graph.c (print_state): Now errors are in red, and
5930 reductions in green.
5931 Prefer high to wide: output the state number on a line of its own.
5932
5933 2001-12-27 Akim Demaille <akim@epita.fr>
5934
5935 * src/state.h, src/state.c (reductions_new): New.
5936 * src/LR0.c (set_state_table): Let all the states have a
5937 `reductions', even if reduced to 0.
5938 (save_reductions): Adjust.
5939 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
5940 * src/print.c (print_reductions, print_actions): Adjust.
5941 * src/output.c (action_row): Adjust.
5942
5943 2001-12-27 Akim Demaille <akim@epita.fr>
5944
5945 * src/state.h, src/state.c (errs_new, errs_dup): New.
5946 * src/LR0.c (set_state_table): Let all the states have an errs,
5947 even if reduced to 0.
5948 * src/print.c (print_errs, print_reductions): Adjust.
5949 * src/output.c (output_actions, action_row): Adjust.
5950 * src/conflicts.c (resolve_sr_conflict): Adjust.

5952 2001-12-27 Akim Demaille <akim@epita.fr>
5953
5954 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
5955
5956 2001-12-27 Akim Demaille <akim@epita.fr>
5957
5958 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
5959 * src/print.c: here.
5960 (lookaheadset, shiftset): New, used as additional storage by
5961 print_reductions.
5962 (print_results): Adjust.
5963 (print_shifts, print_gotos, print_errs): New, extracted from...
5964 (print_actions): here.
5965 * src/print_graph.c (print_actions): Remove dead code.
5966
5967 2001-12-27 Akim Demaille <akim@epita.fr>
5968
5969 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
5970 `$n' and `@n'.
5971
5972 2001-12-27 Akim Demaille <akim@epita.fr>
5973
5974 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
5975 (build_relations): Adjust.
5976
5977 2001-12-27 Akim Demaille <akim@epita.fr>
5978
5979 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
5980 duplication.
5981
5982 2001-12-27 Akim Demaille <akim@epita.fr>
5983
5984 * src/reader.c (packgram): Catch nitems overflows.
5985
5986 2001-12-27 Akim Demaille <akim@epita.fr>
5987
5988 * src/files.c, src/files.h (guard_obstack): Remove.
5989 * src/output.c (output): Adjust.
5990 * src/reader.c (parse_braces): New, factoring...
5991 (copy_action, copy_guard): these two which are renamed as...
5992 (parse_action, parse_guard): these.
5993 As a voluntary consequence, using braces around guards is now
5994 mandatory.
5995
5996 2001-12-27 Akim Demaille <akim@epita.fr>
5997
5998 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
5999 * src/reader.c (symbol_list): `guard' and `guard_line' are new
6000 members.
6001 (symbol_list_new): Adjust.
6002 (copy_action): action_line is the first line, not the last.
6003 (copy_guard): Just as for actions, store the `action' only, not
6004 the switch/case/break flesh.
6005 Don't parse the user action that might follow the guard, let...
6006 (readgram): do it, i.e., now, there can be an action after a
6007 guard.
6008 In other words the guard is just explicitly optional.
6009 (packgram): Adjust.
6010 * src/output.c (guards_output): New.
6011 (output_parser): Call it when needed.
6012 (output): Also free the guard and attrs obstacks.
6013 * src/files.c, src/files.h (obstack_save): Remove.
6014 (output_files): Remove.
6015 As a result, if one needs the former `.act' file, using an
6016 appropriate skeleton which requires actions and guards is now
6017 required.
6018 * src/main.c (main): Adjust.
6019 * tests/semantic.at: New.
6020 * tests/regression.at: Use `input.y' as input file name.
6021 Avoid 8+3 problems by requiring input.c when the test needs the
6022 parser.
6023
6024 2001-12-27 Akim Demaille <akim@epita.fr>
6025
6026 * src/reader.c (symbol_list_new): Be sure to initialize all the
6027 fields.
6028
6029 2001-12-27 Akim Demaille <akim@epita.fr>
6030
6031 All the hacks using a final pseudo state are now useless.
6032
6033 * src/LR0.c (set_state_table): state_table holds exactly nstates.
6034 * src/lalr.c (nLA): New.
6035 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
6036 instead of lookaheadsp from the pseudo state (nstate + 1).
6037
6038 2001-12-27 Akim Demaille <akim@epita.fr>
6039
6040 * src/output.c (action_row, token_actions): Use a state_t instead
6041 of a integer, and nlookaheads instead of the following state's
6042 lookaheadsp.
6043
6044 2001-12-27 Akim Demaille <akim@epita.fr>
6045
6046 * src/conflicts.c (log_resolution, flush_shift)
6047 (resolve_sr_conflict, set_conflicts, solve_conflicts)
6048 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
6049 (conflicts_print, print_reductions): Use a state_t instead of an
6050 integer when referring to a state.
6051 As much as possible, depend upon nlookaheads, instead of the
6052 `lookaheadsp' member of the following state (since lookaheads of
6053 successive states are successive, the difference between state n + 1
6054 and n served as the number of lookaheads for state n).
6055 * src/lalr.c (add_lookback_edge): Likewise.
6056 * src/print.c (print_core, print_actions, print_state)
6057 (print_results): Likewise.
6058 * src/print_graph.c (print_core, print_actions, print_state)
6059 (print_graph): Likewise.
6060 * src/conflicts.h: Adjust.
6061
6062 2001-12-27 Akim Demaille <akim@epita.fr>
6063
6064 * src/bison.hairy: Formatting/comment changes.
6065 ANSIfy.
6066 Remove `register' indications.
6067 Add plenty of `static'.
6068
6069 2001-12-27 Akim Demaille <akim@epita.fr>
6070
6071 * src/output.c (prepare): Drop the muscle `ntbase' which
6072 duplicates ntokens.
6073 * src/bison.simple: Formatting/comment changes.
6074 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
6075 is an undocumented synonym.
6076
6077 2001-12-22 Akim Demaille <akim@epita.fr>
6078
6079 * src/output.c (output_table_data): Change the prototype to use
6080 `int' for array ranges: some invocations do pass an int, not a
6081 short.
6082 Reported by Wayne Green.
6083
6084 2001-12-22 Akim Demaille <akim@epita.fr>
6085
6086 Some actions of web2c.y are improperly triggered.
6087 Reported by Mike Castle.
6088
6089 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
6090 * tests/regression.at (Web2c): Rename as...
6091 (Web2c Report): this.
6092 (Web2c Actions): New.
6093
6094 2001-12-22 Akim Demaille <akim@epita.fr>
6095
6096 Reductions in web2c.y are improperly reported.
6097 Reported by Mike Castle.
6098
6099 * src/conflicts.c (print_reductions): Fix.
6100 * tests/regression.at (Web2c): New.
6101
6102 2001-12-18 Akim Demaille <akim@epita.fr>
6103
6104 Some host fail on `assert (!"foo")', which expands to
6105 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
6106 Reported by Nelson Beebee.
6107
6108 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
6109 `#define it_succeeded 0' and `assert (it_succeeded)'.
6110
6111 2001-12-17 Marc Autret <autret_m@epita.fr>
6112
6113 * src/bison.simple: Don't hard code the skeleton line and filename.
6114 * src/output.c (output_parser): Rename 'line' as 'output_line'.
6115 New line counter 'skeleton_line' (skeleton-line muscle).
6116
6117 2001-12-17 Paul Eggert <eggert@twinsun.com>
6118
6119 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
6120 YYDEBUG must be defined to a nonzero value.
6121
6122 * src/bison.simple (yytname): Do not assume that the user defines
6123 YYDEBUG to a properly parenthesized expression.
6124
6125 2001-12-17 Akim Demaille <akim@epita.fr>
6126
6127 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
6128 nlookaheads is a new member.
6129 Adjust all users.
6130 * src/lalr.h (nlookaheads): Remove this orphan declaration.
6131 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
6132 state.
6133
6134 2001-12-17 Akim Demaille <akim@epita.fr>
6135
6136 * src/files.h, src/files.c (open_files, close_files): Remove.
6137 * src/main.c (main): Don't open/close files, nor invoke lex_free,
6138 let...
6139 * src/reader.c (reader): Do it.
6140
6141 2001-12-17 Akim Demaille <akim@epita.fr>
6142
6143 * src/conflicts.c (print_reductions): Formatting changes.
6144
6145 2001-12-17 Akim Demaille <akim@epita.fr>
6146
6147 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
6148 (flush_reduce): New.
6149 (resolve_sr_conflict): Adjust.
6150
6151 2001-12-17 Akim Demaille <akim@epita.fr>
6152
6153 * src/output.c (output_obstack): Be static and rename as...
6154 (format_obstack): this, to avoid any confusion with files.c's
6155 output_obstack.
6156 * src/reader.h (muscle_obstack): Move to...
6157 * src/output.h: here, since it's defined in output.c.
6158
6159 2001-12-17 Akim Demaille <akim@epita.fr>
6160
6161 * src/output.c (action_row, save_column, default_goto)
6162 (sort_actions, matching_state, pack_vector): Better variable
6163 locality.
6164
6165 2001-12-17 Akim Demaille <akim@epita.fr>
6166
6167 * src/output.c: Various formatting changes.
6168
6169 2001-12-17 Akim Demaille <akim@epita.fr>
6170
6171 * src/files.c (output_files): Free the output_obstack.
6172 * src/main.c (main): Call print and print_graph conditionally.
6173 * src/print.c (print): Work unconditionally.
6174 * src/print_graph.c (print_graph): Work unconditionally.
6175 * src/conflicts.c (log_resolution): Output only if verbose_flag.
6176
6177 2001-12-16 Marc Autret <autret_m@epita.fr>
6178
6179 * src/output.c (actions_output): Fix. When we use %no-lines,
6180 there is one less line per action.
6181
6182 2001-12-16 Marc Autret <autret_m@epita.fr>
6183
6184 * src/bison.simple: Remove a useless #line directive.
6185 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
6186 * src/output.c (get_lines_number): New.
6187 (output_parser): Adjust, now takes care about the lines of a
6188 output muscles.
6189 Fix line numbering.
6190 (actions_output): Computes the number of lines taken by actions.
6191 (output_master_parser): Insert new skeleton which is the name of
6192 the output parser file name.
6193
6194 2001-12-15 Marc Autret <autret_m@epita.fr>
6195
6196 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
6197
6198 2001-12-15 Marc Autret <autret_m@epita.fr>
6199
6200 * src/output.c (output_gram): Keep track of the hairy one.
6201
6202 2001-12-15 Akim Demaille <akim@epita.fr>
6203
6204 Make `make distcheck' work.
6205
6206 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
6207 system.h which uses libgettext.h.
6208
6209 2001-12-15 Akim Demaille <akim@epita.fr>
6210
6211 * src/nullable.c (set_nullable): Useless rules must be skipped,
6212 otherwise, since we range over their symbols, we might look at a
6213 nonterminal which no longer ``exists'', i.e., it is not counted in
6214 `nvars', hence we overflow our arrays.
6215
6216 2001-12-15 Akim Demaille <akim@epita.fr>
6217
6218 The header can also be produced directly, without any obstack!
6219 Yahoo!
6220
6221 * src/files.c, src/files.h (defines_obstack): Remove.
6222 (compute_header_macro): Global.
6223 (defines_obstack_save): Remove.
6224 * src/reader.c (parse_union_decl): No longer output to
6225 defines_obstack: its content can be found in the `stype' muscle
6226 anyway.
6227 (output_token_translations): Merge into...
6228 (symbols_output): this.
6229 Rename as...
6230 (symbols_save): this.
6231 (reader): Adjust.
6232 * src/output.c (header_output): New.
6233 (output): Call it.
6234
6235 2001-12-15 Akim Demaille <akim@epita.fr>
6236
6237 * src/reader.c (parse_union_decl): Instead of handling two obstack
6238 simultaneously, use one to define the `stype' muscle, and use the
6239 value of the latter to fill defines_obstack.
6240 (copy_comment): Remove.
6241 (copy_comment2): Work for a single obstack.
6242 Rename as...
6243 (copy_comment): this.
6244
6245 2001-12-15 Akim Demaille <akim@epita.fr>
6246
6247 * src/lex.c, src/lex.h (xgetc): No longer static.
6248 * src/reader.c (parse_union_decl): Revamp.
6249
6250 2001-12-15 Akim Demaille <akim@epita.fr>
6251
6252 Still making progress in separating Bison into (i) input, (ii)
6253 process, (iii) output: now we can directly output the parser file
6254 without using table_obstack at all.
6255
6256 * src/files.c, src/files.h (table_obstack): Bye bye.
6257 (parser_file_name): New.
6258 * src/files.c (compute_output_file_names): Compute it.
6259 * src/output.c (actions_output, output_parser)
6260 (output_master_parser): To a file instead of an obstack.
6261
6262 2001-12-15 Akim Demaille <akim@epita.fr>
6263
6264 Attach actions to rules, instead of pre-outputting them to
6265 actions_obstack.
6266
6267 * src/gram.h (rule_t): action and action_line are new members.
6268 * src/reader.c (symbol_list): Likewise.
6269 (copy_action): Save the actions within the rule.
6270 (packgram): Save them in rule_table.
6271 * src/output.c (actions_output): New.
6272 (output_parser): Use it on `%%actions'.
6273 (output_rule_data): Don't free rule_table.
6274 (output): Do it.
6275 (prepare): Don't save the `action' muscle.
6276 * src/bison.simple: s/%%action/%%actions/.
6277
6278 2001-12-15 Akim Demaille <akim@epita.fr>
6279
6280 * src/reader.c (copy_action): When --yacc, don't append a `;'
6281 to the user action: let it fail if lacking.
6282 Suggested by Arnold Robbins and Tom Tromey.
6283
6284 2001-12-14 Akim Demaille <akim@epita.fr>
6285
6286 * src/lex.c (literalchar): Simply return the char you decoded, non
6287 longer mess around with obstacks and int pointers.
6288 Adjust all callers.
6289
6290 2001-12-14 Akim Demaille <akim@epita.fr>
6291
6292 * src/lex.c (literalchar): Don't escape the special characters,
6293 just decode them, and keep them as char (before, eol was output as
6294 the 2 char string `\n' etc.).
6295 * src/output.c (output_rule_data): Use quotearg to output the
6296 token strings.
6297
6298 2001-12-13 Paul Eggert <eggert@twinsun.com>
6299
6300 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
6301 Do not infringe on the global user namespace when using C++.
6302 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
6303 All uses of `fprintf' and `stderr' changed.
6304
6305 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
6306
6307 2001-12-13 Akim Demaille <akim@epita.fr>
6308
6309 The computation of nullable is broken: it doesn't handle empty
6310 RHS's properly.
6311
6312 * tests/torture.at (GNU AWK Grammar): New.
6313 * tests/sets.at (Nullable): New.
6314 * src/nullable.c (set_nullable): Instead of blindly looping over
6315 `ritems', loop over the rules, and then over their rhs's.
6316
6317 Work around Autotest bugs.
6318
6319 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
6320 frame, because Autotest understand lines starting with a `+' as
6321 traces from the shell. Then, they are not processed properly.
6322 Admittedly an Autotest bug, but we don't have time to wait for
6323 Autotest to catch up.
6324 * tests/regression.at (Broken Closure): Adjust to the new table
6325 frames.
6326 Move to...
6327 * tests/sets.at: here.
6328
6329 2001-12-13 Akim Demaille <akim@epita.fr>
6330
6331 * src/closure.c (closure): Use nrules instead of playing tricks
6332 with BITS_PER_WORD.
6333
6334 2001-12-13 Akim Demaille <akim@epita.fr>
6335
6336 * src/print.c (print_actions): Output the handling of `$' as the
6337 traces do: shifting the token EOF. Before EOF was treated as a
6338 nonterminal.
6339 * tests/regression.at: Adjust some tests.
6340 * src/print_graph.c (print_core): Complete the set of items via
6341 closure. The next-to-final and final states are still unsatisfying,
6342 but that's to be addressed elsewhere.
6343 No longer output the rule numbers, but do output the state number.
6344 A single loop for the shifts + gotos is enough, but picked a
6345 distinct color for each.
6346 (print_graph): Initialize and finalize closure.
6347
6348 2001-12-13 Akim Demaille <akim@epita.fr>
6349
6350 * src/reader.c (readgram): Remove dead code, an strip useless
6351 braces.
6352 (get_type): Remove, unused.
6353
6354 2001-12-12 Akim Demaille <akim@epita.fr>
6355
6356 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
6357 on that of lib/error.c.
6358
6359 2001-12-12 Akim Demaille <akim@epita.fr>
6360
6361 Some hosts don't like `/' in includes.
6362
6363 * src/system.h: Include libgettext.h without qualifying the path.
6364 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
6365 $(top_srcdir).
6366
6367 2001-12-11 Marc Autret <autret_m@epita.fr>
6368
6369 * src/output.c (output_parser): Remove useless muscle.
6370
6371 2001-12-11 Marc Autret <autret_m@epita.fr>
6372
6373 * src/bison.simple: Remove #line just before %%epilogue. It
6374 is now handled in ...
6375 * src/reader.c (read_additionnal_code): Add the output of a
6376 #line for the epilogue.
6377
6378 2001-12-10 Marc Autret <autret_m@epita.fr>
6379
6380 * src/reader.c (copy_definition): Re-use CPP-outed code which
6381 replace precedent remove.
6382 * src/bison.simple: Remove #line before %%prologue because
6383 %%input-line is wrong at this time.
6384
6385 2001-12-10 Marc Autret <autret_m@epita.fr>
6386
6387 * src/reader.c (symbols_output): Clean up.
6388 * src/output.c (output_gram, output): Clean up.
6389
6390 2001-12-10 Akim Demaille <akim@epita.fr>
6391
6392 * src/lalr.c (initialize_lookaheads): New. Extracted from...
6393 * src/LR0.c (set_state_table): here.
6394 * src/lalr.c (lalr): Call it.
6395
6396 2001-12-10 Akim Demaille <akim@epita.fr>
6397
6398 * src/state.h (shifts): Remove the `number' member: shifts are
6399 attached to state, hence no longer need to be labelled with a
6400 state number.
6401
6402 2001-12-10 Akim Demaille <akim@epita.fr>
6403
6404 Now that states have a complete set of members, the linked list of
6405 shifts is useless: just fill directly the state's shifts member.
6406
6407 * src/state.h (shifts): Remove the `next' member.
6408 * src/LR0.c (first_state, last_state): Remove.
6409 Adjust the callers.
6410 (augment_automaton): Don't look for the shifts that must be added
6411 a shift on EOF: it is those of the state we looked for! But now,
6412 since shifts are attached, it is no longer needed to looking
6413 merely by its id: its number.
6414
6415 2001-12-10 Akim Demaille <akim@epita.fr>
6416
6417 * src/LR0.c (augment_automaton): Better variable locality.
6418 Remove an impossible branch: if there is a state corresponding to
6419 the start symbol being shifted, then there is shift for the start
6420 symbol from the initial state.
6421
6422 2001-12-10 Akim Demaille <akim@epita.fr>
6423
6424 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
6425 only when appropriate: when insert_start_shifting_state' is not
6426 invoked.
6427 * tests/regression.at (Rule Line Numbers): Adjust.
6428
6429 2001-12-10 Akim Demaille <akim@epita.fr>
6430
6431 * src/LR0.c (augment_automaton): Now that all states have shifts,
6432 merge the two cases addition shifts to the initial state.
6433
6434 2001-12-10 Akim Demaille <akim@epita.fr>
6435
6436 * src/lalr.c (set_state_table): Move to...
6437 * src/LR0.c: here.
6438 * src/lalr.c (lalr): Don't call it...
6439 * src/LR0.c (generate_states): do it.
6440 * src/LR0.h (first_state): Remove, only the table is used.
6441
6442 2001-12-10 Akim Demaille <akim@epita.fr>
6443
6444 * src/LR0.h (first_shift, first_reduction): Remove.
6445 * src/lalr.c: Don't use first_shift: find shifts through the
6446 states.
6447
6448 2001-12-10 Akim Demaille <akim@epita.fr>
6449
6450 * src/LR0.c: Attach shifts to states as soon as they are
6451 computed.
6452 * src/lalr.c (set_state_table): Instead of assigning shifts to
6453 state, just assert that the mapping was properly done.
6454
6455 2001-12-10 Akim Demaille <akim@epita.fr>
6456
6457 * src/LR0.c (insert_start_shift): Rename as...
6458 (insert_start_shifting_state): this.
6459 (insert_eof_shifting_state, insert_accepting_state): New.
6460 (augment_automaton): Adjust.
6461 Better locality of the variables.
6462 When looking if the start_symbol is shifted from the initial
6463 state, using `while (... symbol != start_symbol ...)' sounds
6464 better than `while (... symbol < start_symbol ...)': If fail
6465 to see how the order between symbols could be relevant!
6466
6467 2001-12-10 Akim Demaille <akim@epita.fr>
6468
6469 * src/getargs.h: Don't declare `spec_name_prefix' and
6470 `spec_file_prefix', declared by src/files.h.
6471 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
6472 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
6473 * src/output.c (prepare): Adjust.
6474 * src/reader.c (symbols_output): Likewise.
6475 * src/vmsgetargs.c: Vaguely adjust, but who cares?
6476
6477 2001-12-10 Akim Demaille <akim@epita.fr>
6478
6479 * src/muscle_tab.c (muscle_init): NULL is a better default than
6480 `"0"'.
6481
6482 2001-12-10 Akim Demaille <akim@epita.fr>
6483
6484 * src/reader.c (reader): Calling symbols_output once is enough.
6485
6486 2001-12-10 Akim Demaille <akim@epita.fr>
6487
6488 Now that states have a complete set of members, the linked list of
6489 reductions is useless: just fill directly the state's reductions
6490 member.
6491
6492 * src/state.h (struct reductions): Remove member `number' and
6493 `next'.
6494 * src/LR0.c (first_reduction, last_reduction): Remove.
6495 (save_reductions): Don't link the new reductions, store them in
6496 this_state.
6497 * src/lalr.c (set_state_table): No need to attach reductions to
6498 states, it's already done.
6499 * src/output.c (output_actions): No longer free the shifts, then
6500 the reductions, then the states: free all the states and their
6501 members.
6502
6503 2001-12-10 Akim Demaille <akim@epita.fr>
6504
6505 * src/options.c (OPTN, DRTV, BOTH): New.
6506 (option_table): Use them.
6507
6508 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
6509 the job of system.h.
6510 * src/options.c: Don't include stdio.h and xalloc.h for the same
6511 reasons.
6512
6513 2001-12-10 Akim Demaille <akim@epita.fr>
6514
6515 * src/output.c (output, prepare): Make sure the values of the
6516 muscles `action' and `prologue' are 0-terminated.
6517
6518 2001-12-10 Akim Demaille <akim@epita.fr>
6519
6520 Clean up GCC warnings.
6521
6522 * src/reader.c (copy_action): `buf' is not used.
6523 (parse_skel_decl): Be static.
6524 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
6525 * src/options.h (create_long_option_table): Have a real prototype.
6526 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
6527 (hash_delete_at): Return const void *.
6528 Adjust casts to preserve the const.
6529
6530 2001-12-10 Akim Demaille <akim@epita.fr>
6531
6532 * configure.in: Require 2.52g.
6533 M4 is not needed, but AUTOM4TE is.
6534 * m4/m4.m4: Remove.
6535 * tests/Makefile.am: Adjust.
6536
6537 2001-12-10 Akim Demaille <akim@epita.fr>
6538
6539 One structure for states is enough, even though theoretically
6540 there are LR(0) states and LALR(1) states.
6541
6542 * src/lalr.h (state_t): Remove.
6543 (state_table): Be state_t **, not state_t *.
6544 * src/state.h (core, CORE_ALLOC): Rename as...
6545 (state_t, STATE_ALLOC): this.
6546 Add the LALR(1) members: shifts, reductions, errs.
6547 * src/LR0.c (state_table): Rename as...
6548 (state_hash): this, to avoid name clashes with the global
6549 `state_table'.
6550 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
6551 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
6552
6553 2001-12-10 Akim Demaille <akim@epita.fr>
6554
6555 Bison dumps core on bash.y.
6556 Reported by Pascal Bart.
6557
6558 * src/warshall.c (bitmatrix_print): New.
6559 (TC): Use it.
6560 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
6561 j must be the outer loop.
6562 * tests/regression.at (Broken Closure): New.
6563
6564 2001-12-05 Akim Demaille <akim@epita.fr>
6565
6566 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
6567 its argument.

6573 (resolve_sr_conflict): Adjust.
6574 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
6575 Rename as...
6576 (state_t.reductions, state_t.shifts): this.
6577
6578 2001-12-05 Akim Demaille <akim@epita.fr>
6579
6580 * src/reduce.c (reduce_grammar_tables): No longer disable the
6581 removal of useless rules via CPP but via `if (0)', so that the
6582 compiler still check the code is valid.
6583 For instance, it should have noticed `rline' no longer exists: use
6584 the `line' member of rule_t.
6585 * src/gram.c (dummy, rline): Remove, unused.
6586
6587 2001-12-05 Akim Demaille <akim@epita.fr>
6588
6589 * src/output.c (pack_vector): Use assert, not berror.
6590 * src/main.c (berror): Remove, unused.
6591
6592 2001-12-05 Akim Demaille <akim@epita.fr>
6593
6594 New experimental feature: if --verbose --trace output all the
6595 items of a state, not only its kernel.
6596
6597 * src/print.c (print_core): If `trace_flag', then invoke closure
6598 before outputting the items of the state (print_core is no longer
6599 a correct name them).
6600 (print_results): Invoke new_closure/free_closure if needed.
6601
6602 2001-12-05 Akim Demaille <akim@epita.fr>
6603
6604 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
6605 * src/closure.c, src/closure.h (itemsetsize): Rename as...
6606 (nitemset): for consistency with the rest of the project.
6607
6608 2001-12-05 Akim Demaille <akim@epita.fr>
6609
6610 * src/closure.c (print_closure): Improve.
6611 (closure): Use it for printing input and output.
6612
6613 2001-12-05 Akim Demaille <akim@epita.fr>
6614
6615 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
6616 indexed by nonterminals.
6617
6618 2001-12-05 Akim Demaille <akim@epita.fr>
6619
6620 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
6621 what it was!).
6622 * src/warshall.h: Remove accidental duplication of the content.
6623
6624 2001-12-05 Akim Demaille <akim@epita.fr>
6625
6626 * src/closure.c (set_fderives): De-obfuscate.
6627

6631
6632 2001-12-05 Akim Demaille <akim@epita.fr>
6633
6634 * src/closure.c (set_firsts): De-obfuscate.
6635
6636 2001-12-05 Akim Demaille <akim@epita.fr>
6637
6638 * src/output.c (action_row): De-obfuscate
6639 using the good o' techniques: arrays not pointers, variable
6640 locality, BITISSET, RESETBIT etc.
6641
6642 2001-12-05 Akim Demaille <akim@epita.fr>
6643
6644 Pessimize the code to simplify it: from now on, all the states
6645 have a valid SHIFTS, which NSHIFTS is possibly 0.
6646
6647 * src/LR0.c (shifts_new): Be global and move to..
6648 * src/state.c, src/state.h: here.
6649 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
6650 * src/print_graph: Adjust.
6651
6652 2001-12-05 Akim Demaille <akim@epita.fr>
6653
6654 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
6655 * src/conflicts.c: Use it.
6656 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
6657 incorrectly ``simplified''.
6658
6659 2001-12-05 Akim Demaille <akim@epita.fr>
6660
6661 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
6662 using the good o' techniques: arrays not pointers, variable
6663 locality, BITISSET, RESETBIT etc.
6664
6665 2001-12-05 Akim Demaille <akim@epita.fr>
6666
6667 * src/state.h (SHIFT_SYMBOL): New.
6668 * src/conflicts.c: Use it to deobfuscate.
6669
6670 2001-12-05 Akim Demaille <akim@epita.fr>
6671
6672 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
6673 (print_reductions): De-obfuscate using the good o' techniques:
6674 arrays not pointers, variable locality, BITISSET.
6675
6676 2001-12-05 Akim Demaille <akim@epita.fr>
6677
6678 * src/conflicts.c (print_reductions): Arrays, not pointers.
6679 Use BITISSET.
6680
6681 2001-12-05 Akim Demaille <akim@epita.fr>
6682
6683 * src/conflicts.c (print_reductions): Pessimize, but clarify.
6684
6685 2001-12-05 Akim Demaille <akim@epita.fr>
6686

6688
6689 2001-12-05 Akim Demaille <akim@epita.fr>
6690
6691 * src/conflicts.c (print_reductions): Pessimize, but clarify.
6692
6693 2001-12-05 Akim Demaille <akim@epita.fr>
6694
6695 * src/conflicts.c (print_reductions): Improve variable locality.
6696
6697 2001-12-05 Akim Demaille <akim@epita.fr>
6698
6699 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
6700 * src/lalr.c: Use them.
6701
6702 2001-12-05 Akim Demaille <akim@epita.fr>
6703
6704 * src/LR0.c (augment_automaton): Formatting changes.
6705 Better variable locality.
6706
6707 2001-12-05 Akim Demaille <akim@epita.fr>
6708
6709 * src/lalr.c (matrix_print): New.
6710 (transpose): Use it.
6711 Use arrays instead of pointers.
6712
6713 2001-12-05 Akim Demaille <akim@epita.fr>
6714
6715 * src/lalr.c (maxrhs): Move to...
6716 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
6717 * src/lalr.c (build_relations): Adjust.
6718
6719 2001-12-05 Akim Demaille <akim@epita.fr>
6720
6721 * src/lalr.c (transpose): Free the memory allocated to the
6722 argument, as it is replaced by the results by the unique caller.
6723 (build_relations): Merely invoke transpose: it handles the memory
6724 deallocation.
6725 Improve variable locality.
6726 Avoid variables used as mere abbreviations.
6727 (compute_lookaheads): Use arrays instead of pointers.
6728
6729 2001-12-05 Akim Demaille <akim@epita.fr>
6730
6731 * src/lalr.c (initialize_F): Improve variable locality.
6732 Avoid variables used as mere abbreviations.
6733
6734 2001-12-05 Akim Demaille <akim@epita.fr>
6735
6736 * src/derives.c (print_derives): Display the ruleno.
6737 * src/lalr.c (initialize_F, transpose): Better variable locality
6738 to improve readability.
6739 Avoid variables used as mere abbreviations.
6740
6741 2001-12-05 Akim Demaille <akim@epita.fr>
6742
6743 * src/lalr.c (traverse): Use arrays instead of pointers.
6744
6745 2001-12-05 Akim Demaille <akim@epita.fr>
6746
6747 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
6748 the handling of squeue.
6749 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
6750
6751 2001-12-05 Akim Demaille <akim@epita.fr>
6752
6753 Because useless nonterminals are now kept alive (instead of being
6754 `destroyed'), we now sometimes examine them, and store information
6755 related to them. Hence we need to know their number, and adjust
6756 memory allocations.
6757
6758 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
6759 static.
6760 * src/LR0.c (allocate_itemsets): The memory allocated to
6761 `symbol_count' was used for two different purpose: once to count
6762 the number of occurrences of each symbol, and later reassigned to
6763 `shift_symbol', containing the symbol that can be shifted from a
6764 given state.
6765 Deobfuscate, i.e., allocate, use and free `symbol_count' here
6766 only, and...
6767 (new_itemsets): Allocate `shift_symbol' here.
6768 (allocate_itemsets): symbol_count includes useless nonterminals.
6769 Make room for them.
6770 (free_storage): Use `free', not `XFREE', for pointers that cannot
6771 be null.
6772
6773 2001-12-05 Akim Demaille <akim@epita.fr>
6774
6775 * src/nullable.c (set_nullable): Deobfuscate the handling of
6776 ritem.
6777 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
6778
6779 2001-12-05 Akim Demaille <akim@epita.fr>
6780
6781 * src/gram.c, src/gram.h (ritem_print): New.
6782 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
6783 (This useless function was defined only to work around VMS linkers
6784 that can't handle compilation units with variables only).
6785 * src/reduce.c (dump_grammar): Use it to trace the construction of
6786 ritem.
6787
6788 2001-12-04 Paul Eggert <eggert@twinsun.com>
6789
6790 * src/bison.simple (union yyalloc): Change member names
6791 to be the same as the stack names.
6792 (yyparse): yyptr is now union yyalloc *, not char *.
6793 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
6794 and may generate better code on some machines.
6795 (yystpcpy): Use prototype if __STDC__ is defined, not just
6796 if __cplusplus is defined.
6797
6798 2001-11-30 Akim Demaille <akim@epita.fr>
6799
6800 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
6801 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
6802 Gettext doesn't compile cleanly, and dies with -Werror.
6803 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
6804 Include WARNING_CFLAGS here.
6805 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
6806 before being defined.
6807
6808 2001-11-27 Paul Eggert <eggert@twinsun.com>
6809
6810 * lib/quotearg.h (quotearg_n, quotearg_n_style):
6811 First arg is int, not unsigned.
6812 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
6813 (SIZE_MAX, UINT_MAX): New macros.
6814 (quotearg_n_options): Abort if N is negative.
6815 Avoid overflow check on hosts where size_t is 64 bits and int
6816 is 32 bits, as overflow is impossible there.
6817 Fix off-by-one typo that caused unnecessary reallocation.
6818
6819 2001-11-29 Paul Eggert <eggert@twinsun.com>
6820
6821 Name space cleanup in generated parser.
6822
6823 * doc/bison.texinfo (Bison Parser): Discuss system headers
6824 and their effect on the user name space.
6825
6826 * src/bison.simple:
6827 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
6828 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
6829 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
6830
6831 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
6832 on user names when possible.
6833
6834 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
6835 Simplify test for whather <alloca.h> exists.
6836
6837 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
6838
6839 (<stdio.h>): Include if YYDEBUG.
6840
6841 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
6842 ! defined (yyoverflow) && ! defined (yymemcpy).
6843
6844 (yymemcpy, yyparse): Rename local variables as needed so that
6845 they all begin with 'yy'.
6846
6847 (yystrlen, yystpcpy): New functions.
6848
6849 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
6850 All uses changed.
6851
6852 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
6853 instead of relying on string.h functions. Use YYSTACK_ALLOC
6854 and YYSTACK_FREE instead of malloc and free.
6855
6856 2001-11-30 Akim Demaille <akim@epita.fr>
6857
6858 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
6859 before their first uses.

6861
6862 2001-11-30 Akim Demaille <akim@epita.fr>
6863
6864 * tests/reduce.at (Useless Nonterminals): Fix.
6865
6866 2001-11-30 Akim Demaille <akim@epita.fr>
6867
6868 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
6869 if body instead of `;' to pacify GCC's warnings.
6870
6871 2001-11-30 Akim Demaille <akim@epita.fr>
6872
6873 Instead of mapping the LHS of unused rules to -1, keep the LHS
6874 valid, but flag the rules as invalid.
6875
6876 * src/gram.h (rule_t): `useful' is a new member.
6877 * src/print.c (print_grammar): Adjust.
6878 * src/derives.c (set_derives): Likewise.
6879 * src/reader.c (packgram, reduce_output): Likewise.
6880 * src/reduce.c (reduce_grammar_tables): Likewise.
6881 * tests/reduce.at (Underivable Rules, Useless Rules): New.
6882
6883 2001-11-30 Akim Demaille <akim@epita.fr>
6884
6885 * src/reduce.c (reduce_output): Formatting changes.
6886 * src/print.c (print_results, print_grammar): Likewise.
6887 * tests/regression.at (Rule Line Numbers)
6888 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
6889
6890 2001-11-30 Akim Demaille <akim@epita.fr>
6891
6892 * src/reduce.c (nonterminals_reduce): Instead of throwing away
6893 useless nonterminals, move them at the end of the symbol arrays.
6894 (reduce_output): Adjust.
6895 * tests/reduce.at (Useless Nonterminals): Adjust.
6896
6897 2001-11-30 Akim Demaille <akim@epita.fr>
6898
6899 * src/reduce.c: Various comment/formatting changes.
6900 (nonterminals_reduce): New, extracted from...
6901 (reduce_grammar_tables): here.
6902 (reduce_grammar): Call nonterminals_reduce.
6903
6904 2001-11-29 Paul Eggert <eggert@twinsun.com>
6905
6906 * src/bison.simple (YYSTACK_REALLOC): Remove.
6907 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
6908 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
6909 New macros.
6910 (union yyalloc): New type.
6911 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
6912 an arbitrary restriction on hosts where size_t is wider than int.
6913
6914 (yyparse): Don't dump core if alloca or malloc fails; instead, report
6915 a parser stack overflow. Allocate just one block of memory for all
6916 three stacks, instead of allocating three blocks; this typically is
6917 faster and reduces fragmentation.
6918
6919 Do not limit the number of items in the stack to a value that fits
6920 in 'int', as this is an arbitrary limit on hosts with 64-bit
6921 size_t and 32-bit int.
6922
6923 2001-11-29 Marc Autret <autret_m@epita.fr>
6924
6925 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
6926 of defining YYERROR_VERBOSE.
6927 [AT_DATA]: $4 is now out of C declarations in the prologue.
6928
6929 2001-11-28 Marc Autret <autret_m@epita.fr>
6930
6931 * src/reader.c (parse_dquoted_param): New.
6932 (parse_skel_decl): Use it.
6933 * src/lex.h: Add its prototype.
6934 * src/lex.c (literalchar): Become not static.
6935
6936 2001-11-28 Marc Autret <autret_m@epita.fr>
6937
6938 * src/output.h: And put its extern declaration here.
6939 * src/output.c (error_verbose): Define here.
6940 (prepare): Echo name modification.
6941 * src/getargs.h: Clean its extern declaration.
6942 * src/getargs.c (error_verbose_flag): Remove.
6943 (getargs): Remove case 'e'.
6944 * src/options.c (option_table): 'error-verbose' is now seen as simple
6945 percent option.
6946 Include output.h.
6947
6948 * src/reader.c (read_declarations): Remove case tok_include.
6949 (parse_include_decl): Remove.
6950 * src/lex.h (token_t): Remove tok_include.
6951 * src/options.c (option_table): 'include' is now a simple command line
6952 option.
6953
6954 2001-11-28 Marc Autret <autret_m@epita.fr>
6955
6956 * src/bison.simple: Adjust muscle names.
6957 * src/muscle_tab.c (muscle_init): Also rename the muscles.
6958 * src/output.c (prepare): s/_/-/ for the muscles names.

7347
7348 * tests/calc.at, tests/output.at, tests/regression.at,
7349 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
7350 now the tests are run in private dirs, therefore AC_CLEANUP and

7353 use abs. path to find config.h.
7354 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

7359 2001-11-14 Akim Demaille <akim@epita.fr>
7360
7361 * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be

7377 * src/lex.c (parse_percent_token): Replace equal_offset with
7378 arg_offset.
7379 arg is const.
7380 Be sure to strdup `arg' when used, since there is no reason for

7399 (Language and Grammar): ANSIfy the example.
7400 Adjust its layout for info/notinfo.
7401 (Location Tracking Calc): Output error messages to stderr.
7402 Output locations in a more GNUtically correct way.

8738 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

8772
8773 * src/lex.c (percent_table): Also accept `%yacc',
8774 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
8775 `%debug'.
8776 Handle the actions for `%semantic_parser' and `%pure_parser' here,
8777 instead of returning a token.
8778 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
8779 * src/reader.c (read_declarations): Adjust.
8780 * src/files.c (open_files): Don't call `compute_base_names', don't
8781 compute `attrsfile' since they depend upon data which might be
8782 *in* the input file now.
8783 (output_files): Do it here.
8784 * src/output.c (output_headers): Document the fact that this patch
8785 introduces a guaranteed SEGV for semantic parsers.
8786 * doc/bison.texinfo: Document them.
8787 * tests/suite.at: Exercise these %options.
8788

8807
8808 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
8809 (copy_dollar): Now that everything uses obstacks, get rid of the
8810 FILE * parameters.
8811
8812 2000-12-20 Akim Demaille <akim@epita.fr>
8813
8814 * src/files.c (open_files): Actually the `.output' file is based

8817
8818 2000-12-20 Akim Demaille <akim@epita.fr>

8842
8843 * src/files.c (strsuffix): New.
8844 (stringappend): Be just like strcat but allocate.
8845 (base_names): Eve out from open_files.
8846 Try to simplify the rather hairy computation of base_name and

8850

8866
8867 2000-12-19 Akim Demaille <akim@epita.fr>
8868

8886
8887 2000-12-19 Akim Demaille <akim@epita.fr>
8888
8889 * src/files.c (open_files): Yipee! We no longer need all the code
8890 looking for `/tmp' since we have no tmp file.
8891
8892 2000-12-19 Akim Demaille <akim@epita.fr>
8893
8894 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

8920
8921 * lib/obstack.h: Formatting changes.
8922 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
8923 prevents type checking.
8924 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
8925 cast the value to (void *): assigning a `foo *' to a `void *'
8926 variable is valid.
8927 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
8928 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

8932
8933 * tests/Makefile.am (suite.m4, regression.m4, calc.m4): Rename

8942
8943 2000-11-17 Akim Demaille <akim@epita.fr>
8944
8945 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
8946 macros.

8971 * src/output.c (output): Remove useless variables.
8972 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
8973 argument `data' for consistency with the prototypes.
8974 Qualify it `const'.
8975 (obstack_copy, obstack_copy0): Rename the second argument as
8976 `address' for consistency. Qualify it `const'.
8977 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
8978 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
8979 `const' their input argument (`data' or `address').
8980 Adjust the corresponding macros to include `const' in casts.
8981
8982 2000-11-03 Akim Demaille <akim@epita.fr>
8983

9003
9004 * src/files.c (obstack_save): New function.
9005 (done): Rename as...
9006 (output_files): this.
9007 Use `obstack_save'.
9008 * src/main.c (main): Don't use `atexit' to register `done', since
9009 it no longer has to remove tmp files, just call `output_files'
9010 when there are no errors.
9011
9012 2000-11-02 Akim Demaille <akim@epita.fr>
9013

9021
9022 * src/files.c (fdefines, ftable): Removed.
9023 (defines_ostack, table_obstack): New.

9033
9034 Change each use of `fattrs' into a use of `attrs_obstack'.
9035
9036 * src/reader.c (copy_at): Typo: s/yylloc/yyloc/.
9037 * src/files.c (fattrs): Remove.

9072
9073 2000-10-16 Akim Demaille <akim@epita.fr>
9074
9075 * src/lex.c (read_typename): New function.
9076 (lex): Use it.
9077 * src/reader.c (copy_dollar): Likewise.
9078
9079 2000-10-16 Akim Demaille <akim@epita.fr>
9080
9081 * src/reader.c (copy_comment2): Expect the input stream to be on
9082 the `/' which is suspected to open a comment, instead of being
9083 called after `//' or `/*' was read.
9084 (copy_comment, copy_definition, parse_union_decl, copy_action)
9085 (copy_guard): Adjust.
9086
9087 2000-10-16 Akim Demaille <akim@epita.fr>
9088
9089 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

9093
9094 * src/reader.c (copy_dollar): New function.

9096
9097 2000-10-16 Akim Demaille <akim@epita.fr>
9098
9099 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:

9104
9105 2000-10-04 Akim Demaille <akim@epita.fr>
9106
9107 * lib/error.c, lib/error.h: New files, needed by xmalloc.c.
9108
9109 2000-10-04 Akim Demaille <akim@epita.fr>
9110
9111 * doc/bison.texinfo: Various typos spotted by Neil Booth.
9112
9113 2000-10-04 Akim Demaille <akim@epita.fr>
9114
9115 When a literal string is used to define two different tokens,
9116 `bison -v' segfaults.
9117 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
9118
9119 * tests/regression.m4: New file.
9120 Include the core of the sample provided by Piotr Gackiewicz.

9122 properly.
9123
9124 2000-10-04 Akim Demaille <akim@epita.fr>
9125
9126 * src/reader.c (parse_expect_decl): Keep `count' within the size
9127 of `buffer'.
9128 From Neil Booth.
9129
9130 2000-10-02 Paul Eggert <eggert@twinsun.com>
9131
9132 * bison.s1 (yyparse): Assign the default value
9133 unconditionally, to avoid a GCC warning and make the parser a
9134 tad smaller.
9135
9136 2000-10-02 Akim Demaille <akim@epita.fr>
9137
9138 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
9139 options.
9140
9141 2000-10-02 Akim Demaille <akim@epita.fr>
9142
9143 * src/derives.c, src/print.c, src/reduce.c: To ease the
9144 translation, move some `\n' out of the translated strings.
9145
9146 2000-10-02 Akim Demaille <akim@epita.fr>
9147
9148 The location tracking mechanism is precious for parse error
9149 messages. Nevertheless, it is enabled only when `@n' is used in
9150 the grammar, which is a different issue (you can use it in error
9151 message, but not in the grammar per se). Therefore, there should
9152 be another means to enable it.
9153
9154 * src/getargs.c (getargs): Support `--locations'.
9155 (usage): Report it.
9156 * src/getargs.h (locationsflag): Export it.
9157 * src/lex.c (percent_table): Support `%locations'.
9158 * src/reader.c (yylsp_needed): Remove this variable, now replaced
9159 with `locationsflag'.
9160 * doc/bison.texinfo: Document `--locations' and `%locations'.
9161 Sort the options.
9162 * tests/calc.m4: Test it.
9163
9164 For regularity of the names, replace each
9165 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
9166 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
9167 In addition replace each `flag' with `_flag'.
9168
9169 2000-10-02 Akim Demaille <akim@epita.fr>
9170
9171 Also test parse error messages, including with YYERROR_VERBOSE.
9172
9173 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
9174 associative).
9175 Use it to check the computations.
9176 Use it to check `nonassoc' is honored.
9177 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
9178 `--yyerror-verbose'.
9179 (_AT_CHECK_CALC): Adjust to this option.
9180 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
9181
9182 2000-10-02 Akim Demaille <akim@epita.fr>
9183
9184 Test also `--verbose', `--defines' and `--name-prefix'. Testing
9185 the latter demonstrates a flaw in the handling of non debugging
9186 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
9187 was used in order to simplify:
9188
9189 #if YYDEBUG
9190 if (yydebug)
9191 {
9192 ...
9193 }
9194 #endif
9195
9196 into
9197
9198 if (yydebug)
9199 {
9200 ...
9201 }
9202
9203 unfortunately this leads to a CPP conflict when
9204 `--name-prefix=foo' is used since it produces `#define yydebug
9205 foodebug'.
9206
9207 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
9208 (YYDPRINTF): New macro.
9209 Spread its use.
9210 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
9211 the bison options.
9212 Also test `--verbose', `--defines' and `--name-prefix'.
9213
9214 2000-10-02 Akim Demaille <akim@epita.fr>
9215
9216 Improve the readability of the produced parsers.
9217
9218 * src/bison.s1: Formatting changes.
9219 Improve the comment related to the `$' mark.
9220 (yydefault): Don't fall through to `yyresume': `goto' there.
9221 * src/output.c (output_parser): When the `$' is met, skip the end
9222 of its line.
9223 New variable, `number_of_dollar_signs', to check there's exactly
9224 one `$' in the parser skeleton.
9225
9226 2000-10-02 Akim Demaille <akim@epita.fr>
9227
9228 * lib/xstrdup.c: New file, from the fileutils.
9229 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
9230 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
9231 instead of strlen + xmalloc + strcpy.
9232 * src/symtab.c (copys): Remove, use xstrdup instead.
9233
9234 2000-10-02 Akim Demaille <akim@epita.fr>
9235
9236 * src/gram.h (associativity): New enum type which replaces the
9237 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
9238 `right_assoc', `left_assoc' and `non_assoc'.
9239 Adjust all dependencies.
9240 * src/reader.c: Formatting changes.
9241 (LTYPESTR): Don't define it, use it as a literal in
9242 `reader_output_yylsp'.
9243 * src/symtab.h (symbol_class): New enum type which replaces the
9244 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
9245 `sunknown', `stoken and `snterm'.
9246
9247 2000-10-02 Akim Demaille <akim@epita.fr>
9248
9249 * src/getargs.c (fixed_outfiles): Rename as...
9250 (yaccflag): for consistency and accuracy.
9251 Adjust dependencies.
9252
9253 2000-10-02 Akim Demaille <akim@epita.fr>
9254
9255 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
9256 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
9257 difficult and introduced a lot of core dump. It turns out that
9258 Bison used an implementation of `xmalloc' based on `calloc', and
9259 at various places it does depend upon the initialization to 0. I
9260 have not tried to isolate the pertinent places, and all the former
9261 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
9262 someone should address this issue.
9263
9264 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
9265 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

9362
9363 2000-10-02 Akim Demaille <akim@epita.fr>
9364
9365 `user_toknums' is output as a `short[]' in `output.c', while it is
9366 defined as a `int[]' in `reader.c'. For consistency with the
9367 other output tables, `user_toknums' is now defined as a table of
9368 shorts.

9387 from output.c.

9409 inclusion.
9410 Don't define PARAMS.
9411 * src/system.h: Define PARAMS.
9412 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
9413 purpose of config.h. system.h must not try to fix wrong
9414 definitions in config.h.
9415
9416 2000-09-20 Akim Demaille <akim@epita.fr>
9417

9549 * lib/: New directory.
9550 * Makefile.am (SUBDIRS): Adjust.
9551 * configure.in: Adjust.

9579
9580 On syntax errors, report the token on which we choked.

9628 (copy_guard): Likewise.
9629
9630 2000-03-17 Akim Demaille <akim@epita.fr>
9631
9632 Change the handling of @s so that they behave exactly like $s.
9633 There is now a pseudo variable @$ (readble and writable), location
9634 of the lhs of the rule (by default ranging from the location of
9635 the first symbol of the rhs, to the location of the last symbol,
9636 or, if the rhs is empty, YYLLOC).
9637
9638 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
9639 yyval.
9640 (yyparse): When providing a default semantic action, provide a

9663 * src/output.c (output_rule_data): Output the documentation of

9668 2000-03-16 Akim Demaille <akim@epita.fr>
9669
9670 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
9671 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
9672 One `#if YYDEBUG' remains, since it uses variables which are
9673 defined only if `YYDEBUG != 0'.
9674
9675 2000-03-16 Akim Demaille <akim@epita.fr>
9676

9687
9688 2000-03-16 Akim Demaille <akim@epita.fr>

9707 the proper line number and file name.
9708 (DEFS): Propagate the location of bison library files and of the
9709 locale files.
9710 (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
9711 builddir.
9712 * acinclude.m4: Remove, replaced by the directory m4.
9713 * m4/Makefile.am (EXTRA_DIST): New variable.
9714 * m4/gettext.m4: New file, from the fileutils.

9720
9721 * src/closure.c:
9722 Formatting changes of various comments.
9723 Respect the GNU coding standards at various places.
9724 Don't use `_()' when no translation is needed.

10350 declaration to allow a multi-character symbol as an alias.
10351 (parse_thong_decl): New function.

10362 Revised and use multiple warnxxx functions to avoid using VARARGS1.
10363 (read_declarations): Improve the error message for
10364 an invalid character. Do not abort.
10365 (read_declarations, copy_guard, copy_action): Use
10366 printable_version to avoid unprintable characters in printed output.

10390 (safegetc): New function to deal with EOF gracefully.
10391 (literalchar); new function to deal with reading \ escapes.
10392 (lex): Use literalchar.
10393 (lex): Implemented "..." tokens.
10394 (literalchar, lex, parse_percent_token): Made tokenbuffer
10395 always contain the token. This includes growing the token
10396 buffer while reading an integer.
10397 (parse_percent_token): Replaced if-else statement with percent_table.
10398 (parse_percent_token): Added % declarations as another
10399 way to specify the flags -n, -l, and -r. Also added hooks for
10400 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
10401 major changes to files.c.
10402 (lex) Retain in the incoming stream a character following
10403 an incorrect '/'.
10404 (skip_white_space, lex): Revised most error messages
