2
3 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
4 C++ parsers.
5 (yy::b4_name::parse): Build verbose error messages, and use error_.
6
7 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
8
9 * data/bison.c++: Fix m4 quoting in comments.
10
11 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
12
13 * data/bison.c++: Adjust the parser code. Fix some muscles that were
14 not expanded by m4.
15
16 2002-02-05 Akim Demaille <akim@epita.fr>
17
18 * data/bison.c++: Adjust to the M4 back end.
19 More is certainly needed.
20
21 2002-02-05 Akim Demaille <akim@epita.fr>
22
23 Give a try to M4 as a back end.
24
25 * lib/readpipe.c: New, from wdiff.
26 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
27 BISON_HAIRY.
28 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
29 specific values. Now it is m4 that performs the lookup.
30 * src/parse-skel.y: Remove.
31 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
32 * src/output.c (actions_output, guards_output)
33 (token_definitions_output): No longer keeps track of the output
34 line number, hence remove the second argument.
35 (guards_output): Check against the guard member of a rule, not the
36 action member.
37 Adjust callers.
38 (output_skeleton): Don't look for the skeleton location, let m4 do
39 that.
40 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
41 file will be used.
42 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
43 (prepare): Given that for the time being changesyntax is not
44 usable in M4, rename the muscles using `-' to `_'.
45 Define `defines_flag', `output_parser_name' and `output_header_name'.
46 * src/output.h (actions_output, guards_output)
47 (token_definitions_output): Adjust prototypes.
48 * src/scan-skel.l: Instead of scanning the skeletons, it now
49 processes the output of m4: `__oline__' and `#output'.
50 * data/bison.simple: Adjust to be used by M4(sugar).
51 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
52 to date.
53 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
54 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
55 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
56 shamelessly stolen from CVS Autoconf.
57
58 2002-02-05 Akim Demaille <akim@epita.fr>
59
60 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
61 * configure.in: Check for the declarations of free and malloc.
62 * src/muscle_tab.c: Adjust.
63
64 2002-02-05 Akim Demaille <akim@epita.fr>
65
66 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
67 which have no values.
68
69 2002-02-05 Akim Demaille <akim@epita.fr>
70
71 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
72 * data/: here.
73
74 2002-01-29 Paul Eggert <eggert@twinsun.com>
75
76 * src/bison.simple (YYSIZE_T): Do not define merely because
77 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
78 On some platforms, <alloca.h> does not declare YYSTD (size_t).
79
80 2002-01-27 Akim Demaille <akim@epita.fr>
81
82 Fix `%nonassoc and eof'.
83
84 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
85 which were not properly copied! Replace
86 memcpy (res->errs, src->errs, src->nerrs);
87 with
88 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
89 !!!
90 * tests/regression.at (%nonassoc and eof): Adjust to newest
91 Autotest: `.' is not in the PATH.
92
93 2002-01-27 Akim Demaille <akim@epita.fr>
94
95 * tests/sets.at (AT_EXTRACT_SETS): New.
96 (Nullable): Use it.
97 (Firsts): New.
98
99 2002-01-26 Akim Demaille <akim@epita.fr>
100
101 * tests/actions.at, tests/calc.at, tests/headers.at,
102 * tests/torture.at: Adjust to the newest Autotest which no longer
103 forces `.' in the PATH.
104
105 2002-01-25 Akim Demaille <akim@epita.fr>
106
107 * tests/regression.at (%nonassoc and eof): New.
108 Suggested by Robert Anisko.
109
110 2002-01-24 Akim Demaille <akim@epita.fr>
111
112 Bison dumps core when trying to complain about broken input files.
113 Reported by Cris van Pelt.
114
115 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
116 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
117 into...
118 (Invalid inputs): Strengthen: exercise parse_percent_token.
119
120 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
121
122 * src/Makefile.am: Add bison.c++.
123 * src/bison.c++: New skeleton.
124
125 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
126
127 * po/it.po: New.
128
129 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
130
131 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
132
133 2002-01-20 Marc Autret <marc@gnu.org>
134
135 * src/files.c (compute_output_file_names): Fix
136
137 2002-01-20 Marc Autret <marc@gnu.org>
138
139 * tests/output.at: New test.
140 * src/files.c (compute_base_names): Don't map extensions when
141 the YACC flag is set, use defaults.
142 Reported by Evgeny Stambulchik.
143
144 2002-01-20 Marc Autret <marc@gnu.org>
145
146 * src/system.h: Need to define __attribute__ away for non-GCC
147 compilers as well (i.e. the vendor C compiler).
148 Suggested by Albert Chin-A-Young.
149
150 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
151
152 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
153 canonical definition.
154 * src/system.h: Use the canonical definition for PARAMS (avoids
155 a conflict with the macro from lib/hash.h).
156
157 2002-01-11 Akim Demaille <akim@epita.fr>
158
159 * configure.in: Use AC_FUNC_STRNLEN.
160 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
161
162 2002-01-09 Akim Demaille <akim@epita.fr>
163
164 * src/files.c, src/files.h (output_infix): New.
165 (tab_extension): Remove.
166 (compute_base_names): Compute the former, drop the latter.
167 * src/output.c (prepare): Insert the muscles `output-infix', and
168 `output-suffix'.
169 * src/parse-skel.y (string, string.1): New.
170 (section.header): Use it.
171 (section.yacc): Remove.
172 (prefix): Remove too.
173 * src/scan-skel.l: Adjust.
174 * src/bison.simple, src/bison.hairy: Adjust.
175
176 2002-01-09 Akim Demaille <akim@epita.fr>
177
178 * configure.in (WERROR_CFLAGS): Compute it.
179 * src/Makefile.am (CFLAGS): Pass it.
180 * tests/atlocal.in (CFLAGS): Idem.
181 * src/files.c: Fix a few warnings.
182 (get_extension_index): Remove, unused.
183
184 2002-01-08 Akim Demaille <akim@epita.fr>
185
186 * src/getargs.c (AS_FILE_NAME): New.
187 (getargs): Use it to convert DOSish file names.
188 * src/files.c (base_name): Rename as full_base_name to avoid
189 clashes with `base_name ()'.
190 (filename_split): New.
191 (compute_base_names): N-th rewrite, using filename_split.
192
193 2002-01-08 Akim Demaille <akim@epita.fr>
194
195 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
196 New, stolen from the Fileutils 4.1.
197 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
198 * configure.in: Check for the presence of memrchr, and of its
199 prototype.
200
201 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
202
203 * lib/hash.h (__P): Added definition for this macro.
204 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
205 BUILT_SOURCES, to ensure they are generated first.
206 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
207 %error-verbose to allow bootstrapping with bison 1.30x.
208
209 2002-01-06 Akim Demaille <akim@epita.fr>
210
211 * src/reader.c (parse_braces): Don't fetch the next char, the
212 convention is to fetch on entry.
213 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
214 'switch' without a following semicolon.
215 * tests/regression.at (braces parsing): New.
216
217 2002-01-06 Akim Demaille <akim@epita.fr>
218
219 Bison is dead wrong in its RR conflict reports.
220
221 * tests/torture.at (GNU Cim Grammar): New.
222 * src/conflicts.c (count_rr_conflicts): Fix.
223
224 2002-01-06 Akim Demaille <akim@epita.fr>
225
226 Creating package.m4 from configure.ac causes too many problems.
227
228 * tests/Makefile.am (package.m4): Create it by hand,
229 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
230
231 2002-01-06 Akim Demaille <akim@epita.fr>
232
233 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
234 skeleton.h.
235
236 2002-01-04 Paul Eggert <eggert@twinsun.com>
237
238 * doc/bison.texinfo (Debugging):
239 Remove YYSTDERR; it's no longer defined or used.
240 Also, s/cstdio.h/cstdio/.
241
242 2002-01-03 Akim Demaille <akim@epita.fr>
243
244 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
245
246 2002-01-03 Akim Demaille <akim@epita.fr>
247
248 * src/parse-skel.y (process_skeleton): Don't bind the parser's
249 tracing code to --trace, wait for a better --trace option, with
250 args.
251
252 2002-01-03 Akim Demaille <akim@epita.fr>
253
254 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
255 The ISO C++ standard is extremely clear about it: stderr is
256 considered a macro, not a regular symbol (see table 94 `Header
257 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
258 Therefore std:: does not apply to it. It still does with fprintf.
259 Also, s/cstdio.h/cstdio/.
260
261 2002-01-03 Akim Demaille <akim@epita.fr>
262
263 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
264 for non system headers.
265
266 2002-01-02 Akim Demaille <akim@epita.fr>
267
268 Equip the skeleton chain with location tracking, runtime trace,
269 pure parser and scanner.
270
271 * src/parse-skel.y: Request a pure parser, locations, and prefix
272 renaming.
273 (%union): Having several members with the same type does not help
274 type mismatches, simplify.
275 (YYPRINT, yyprint): New.
276 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
277 (skel_error): this.
278 Handle locations.
279 * src/scan-skel.l: Adjust to these changes.
280 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
281 (LOCATION_PRINT, skel_control_t): New.
282
283 2001-12-30 Akim Demaille <akim@epita.fr>
284
285 * src/parse-skel.y: Get rid of the shift/reduce conflict:
286 replace `gb' with BLANKS.
287 * src/scan-skel.l: Adjust.
288
289 2001-12-30 Akim Demaille <akim@epita.fr>
290
291 * src/system.h: We don't need nor want bcopy.
292 Throw away MS-DOS crap: we don't need getpid.
293 * configure.in: We don't need strndup. It was even causing
294 problems: because Flex includes the headers *before* us,
295 _GNU_SOURCE is not defined by config.h, and therefore strndup was
296 not visible.
297 * lib/xstrndup.c: New.
298 * src/scan-skel.l: Use it.
299 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
300 * src/parse-skel.y: Use %directives instead of #defines.
301
302 2001-12-30 Akim Demaille <akim@epita.fr>
303
304 * src/skeleton.h: New.
305 * src/output.c (output_parser, output_master_parser): Remove, dead
306 code.
307 * src/output.h (get_lines_number, actions_output, guards_output)
308 (token_definitions_output): Prototype them.
309 * src/parse-skel.y: Add the license notice.
310 Include output.h and skeleton.h.
311 (process_skeleton): Returns void, and takes a single parameter.
312 * src/scan-skel.l: Add the license notice.
313 Include skeleton.h.
314 Don't use %option yylineno: it seems that then Flex imagines
315 REJECT has been used, and therefore it won't reallocate its
316 buffers (which makes no other sense to me than a bug). It results
317 in warnings for `unused: yy_flex_realloc'.
318
319 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
320
321 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
322 (MUSCLE_INSERT_PREFIX): ...to there.
323 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
324 (MUSCLE_INSERT_PREFIX): Move from here...
325
326 * src/bison.hairy: Add a section directive. Put braces around muscle
327 names. This parser skeleton is still broken, but Bison should not
328 choke on a bad muscle 'syntax'.
329 * src/bison.simple: Add a section directive. Put braces around muscle
330 names.
331
332 * src/files.h (strsuffix, stringappend): Add declarations.
333 (tab_extension): Add declaration.
334 (short_base_name): Add declaration.
335
336 * src/files.c (strsuffix, stringappend): No longer static. These
337 functions are used in the skeleton parser.
338 (tab_extension): New.
339 (compute_base_names): Use the computations done in this function
340 to guess if the generated parsers should have '.tab' in their
341 names.
342 (short_base_name): No longer static.
343
344 * src/output.c (output_skeleton): New.
345 (output): Disable call to output_master_parser, and give a try to
346 a new skeleton handling system.
347 (guards_output, actions_output): No longer static.
348 (token_definitions_output, get_lines_number): No longer static.
349
350 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
351
352 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
353 parse-skel.y.
354
355 * src/parse-skel.y: New file.
356 * src/scan-skel.l: New file.
357
358 2001-12-29 Akim Demaille <akim@epita.fr>
359
360 %name-prefix is broken.
361
362 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
363 Adjust all dependencies.
364 * tests/headers.at (export YYLTYPE): Strengthen this test: use
365 %name-prefix.
366
367 Renaming yylval but not yylloc is not consistent. Now we do.
368
369 * src/bison.simple: Prefix yylloc if used.
370 * doc/bison.texinfo (Decl Summary): Document that.
371
372 2001-12-29 Akim Demaille <akim@epita.fr>
373
374 * doc/bison.texinfo: Promote `%long-directive' over
375 `%long_directive'.
376 Remove all references to fixed-output-files, yacc is enough.
377
378 2001-12-29 Akim Demaille <akim@epita.fr>
379
380 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
381 user prologue. These are defaults.
382 * tests/actions.at (Mid-rule actions): Make sure the user can
383 define YYDEBUG and YYERROR_VERBOSE.
384
385 2001-12-29 Akim Demaille <akim@epita.fr>
386
387 * src/output.c (header_output): Don't forget to export YYLTYPE and
388 yylloc.
389 * tests/headers.at (export YYLTYPE): New, make sure it does.
390 * tests/regression.at (%union and --defines, Invalid CPP headers):
391 Move to...
392 * tests/headers.at: here.
393
394 2001-12-29 Akim Demaille <akim@epita.fr>
395
396 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
397
398 2001-12-29 Akim Demaille <akim@epita.fr>
399
400 * tests/actions.at (Mid-rule actions): Output on a single line
401 instead of several.
402
403 2001-12-29 Akim Demaille <akim@epita.fr>
404
405 * doc/bison.texinfo: Formatting changes.
406
407 2001-12-29 Akim Demaille <akim@epita.fr>
408
409 Don't store the token defs in a muscle, just be ready to output it
410 on command. Now possible via `symbols'. Fixes a memory leak.
411
412 * src/output.c (token_definitions_output): New.
413 (output_parser, header_output): Use it.
414 * src/reader.c (symbols_save): Remove.
415
416 2001-12-29 Akim Demaille <akim@epita.fr>
417
418 * src/bison.simple: Do not provide a default for YYSTYPE and
419 YYLTYPE before the user's prologue. Otherwise it's hardly... a
420 default.
421
422 2001-12-29 Akim Demaille <akim@epita.fr>
423
424 Mid-rule actions are simply... ignored!
425
426 * src/reader.c (readgram): Be sure to attach mid-rule actions to
427 the empty-rule associated to the dummy symbol, not to the host
428 rule.
429 * tests/actions.at (Mid-rule actions): New.
430
431 2001-12-29 Akim Demaille <akim@epita.fr>
432
433 Memory leak.
434
435 * src/reader.c (reader): Free grammar.
436
437 2001-12-29 Akim Demaille <akim@epita.fr>
438
439 Memory leak.
440
441 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
442 since it allocates it for each state, although only one is needed.
443 (allocate_storage): Do it here.
444
445 2001-12-29 Akim Demaille <akim@epita.fr>
446
447 * src/options.h, src/options.c (create_long_option_table): Rename
448 as...
449 (long_option_table_new): this, with a clearer prototype.
450 (percent_table): Remove, unused,
451 * src/getargs.c (getargs): Adjust.
452
453 2001-12-29 Akim Demaille <akim@epita.fr>
454
455 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
456 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
457 as states.
458
459 2001-12-29 Akim Demaille <akim@epita.fr>
460
461 * src/lalr.c (build_relations): Rename `states' as `states1'.
462 Sorry, I don't understand exactly what it is, no better name...
463
464 2001-12-29 Akim Demaille <akim@epita.fr>
465
466 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
467 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
468 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
469 as rules.
470
471 2001-12-29 Akim Demaille <akim@epita.fr>
472
473 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
474 ago.
475
476 2001-12-29 Akim Demaille <akim@epita.fr>
477
478 * src/reader.c, src/reader.h (user_toknums): Remove.
479 Adjust all users to use symbols[i]->user_token_number.
480
481 2001-12-29 Akim Demaille <akim@epita.fr>
482
483 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
484 Adjust all users to use symbols[i]->prec or ->assoc.
485
486 2001-12-29 Akim Demaille <akim@epita.fr>
487
488 * src/reader.c, src/reader.h (tags): Remove.
489 Adjust all users to use symbols[i]->tag.
490
491 2001-12-29 Akim Demaille <akim@epita.fr>
492
493 * src/gram.h, src/gram.c (symbols): New, similar to state_table
494 and rule_table.
495 * src/reader.c (packsymbols): Fill this table.
496 Drop sprec.
497 * src/conflicts.c (resolve_sr_conflict): Adjust.
498 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
499 single table.
500 Use symbols[i]->tag instead of tags[i].
501
502 2001-12-29 Akim Demaille <akim@epita.fr>
503
504 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
505 In addition, put a comment in there, to replace...
506 * tests/regression.at (%union and C comments): Remove.
507
508 2001-12-29 Akim Demaille <akim@epita.fr>
509
510 * tests/regression.at (Web2c Actions): Blindly move the actual
511 output as expected output. The contents *seem* right to me, but I
512 can't pretend reading perfectly parser tables... Nonetheless, all
513 the other tests pass correctly, the table look OK, even though the
514 presence of `$axiom' is to be noted: AFAICS it is useless (but
515 harmless).
516
517 2001-12-29 Akim Demaille <akim@epita.fr>
518
519 * src/reader.c (readgram): Don't add the rule 0 if there were no
520 rules read. In other words, add it _after_ having performed
521 grammar sanity checks.
522 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
523
524 2001-12-29 Akim Demaille <akim@epita.fr>
525
526 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
527 visible, and some states have now a different number.
528
529 2001-12-29 Akim Demaille <akim@epita.fr>
530
531 * src/reader.c (readgram): Bind the initial rule's lineno to that
532 of the first rule.
533 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
534 (Solved SR Conflicts): Adjust rule 0's line number.
535
536 2001-12-29 Akim Demaille <akim@epita.fr>
537
538 Fix the `GAWK Grammar' failure.
539
540 * src/LR0.c (final_state): Initialize to -1 so that we do compute
541 the reductions of the first state which was mistakenly confused
542 with the final state because precisely final_state was initialized
543 to 0.
544 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
545 now noticed by Bison.
546 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
547 have a reduction on $default.
548
549 2001-12-29 Akim Demaille <akim@epita.fr>
550
551 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
552 rule line numbers.
553 * src/closure.c (print_closure): Likewise.
554 * src/derives.c (print_derives): Likewise.
555 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
556 now.
557
558 2001-12-29 Akim Demaille <akim@epita.fr>
559
560 * src/lalr.c (lookaheads_print): New.
561 (lalr): Call it when --trace-flag.
562 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
563 are dumped.
564
565 2001-12-29 Akim Demaille <akim@epita.fr>
566
567 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
568 when walking through ritem, even via rule->rhs.
569 * src/reduce.c (dump_grammar, useful_production, reduce_output)
570 (useful_production, useless_nonterminals): Likewise.
571 (reduce_grammar_tables): Likewise, plus update nritems.
572 * src/nullable.c (set_nullable): Likewise.
573 * src/lalr.c (build_relations): Likewise.
574 * tests/sets.at (Nullable): Adjust.
575 Fortunately, now, the $axiom is no longer nullable.
576
577 2001-12-29 Akim Demaille <akim@epita.fr>
578
579 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
580 the 0-sentinel.
581 * src/gram.c (ritem_longest_rhs): Likewise.
582 * src/reduce.c (nonterminals_reduce): Likewise.
583 * src/print_graph.c (print_graph): Likewise.
584 * src/output.c (output_rule_data): Likewise.
585 * src/nullable.c (set_nullable): Likewise.
586
587 2001-12-29 Akim Demaille <akim@epita.fr>
588
589 * src/output.c: Comment changes.
590
591 2001-12-27 Paul Eggert <eggert@twinsun.com>
592
593 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
594 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
595 Sparc, as they were causing more porting problems than the
596 (minor) performance improvement was worth.
597
598 Also, catch up with 1.31's YYSTD.
599
600 2001-12-27 Akim Demaille <akim@epita.fr>
601
602 * src/output.c (output_gram): Rely on nritems, not the
603 0-sentinel. See below.
604 Use -1 as separator, not 0.
605 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
606 Rely on -1 as separator in yyrhs, instead of 0.
607 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
608 twice `Now at end of input', therefore there are two lines less to
609 expect.
610
611 2001-12-27 Akim Demaille <akim@epita.fr>
612
613 * tests/regression.at (Unresolved SR Conflicts):
614 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
615 below.
616
617 2001-12-27 Akim Demaille <akim@epita.fr>
618
619 * src/LR0.c (new_state): Recognize the final state by the fact it
620 is reached by eoftoken.
621 (insert_start_shifting_state, insert_eof_shifting_state)
622 (insert_accepting_state, augment_automaton): Remove, since now
623 these states are automatically computed from the initial state.
624 (generate_states): Adjust.
625 * src/print.c: When reporting a rule number to the user, substract
626 1, so that the axiom rule is rule 0, and the first user rule is 1.
627 * src/reduce.c: Likewise.
628 * src/print_graph.c (print_core): For the time being, just as for
629 the report, depend upon --trace-flags to dump the full set of
630 items.
631 * src/reader.c (readgram): Once the grammar read, insert the rule
632 0: `$axiom: START-SYMBOL $'.
633 * tests/set.at: Adjust: rule 0 is now displayed, and since the
634 number of the states has changed (the final state is no longer
635 necessarily the last), catch up.
636
637 2001-12-27 Akim Demaille <akim@epita.fr>
638
639 Try to make the use of the eoftoken valid. Given that its value
640 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
641 is used instead of > 0 where appropriate, (ii), depend upon nritems
642 instead of the 0-sentinel.
643
644 * src/gram.h, src/gram.c (nritems): New.
645 Expected to be duplication of nitems, but for the time being...
646 * src/reader.c (packgram): Assert nritems and nitems are equal.
647 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
648 * src/closure.c (print_closure, print_fderives): Likewise.
649 * src/gram.c (ritem_print): Likewise.
650 * src/print.c (print_core, print_grammar): Likewise.
651 * src/print_graph.c: Likewise.
652
653 2001-12-27 Akim Demaille <akim@epita.fr>
654
655 * src/main.c (main): If there are complains after grammar
656 reductions, then output the report anyway if requested, then die.
657 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
658 * src/reader.c (eoftoken): New.
659 (parse_token_decl): If the token being defined has value `0', it
660 is the eoftoken.
661 (packsymbols): No longer hack `tags' to insert `$' by hand.
662 Be sure to preserve the value of the eoftoken.
663 (reader): Make sure eoftoken is defined.
664 Initialize nsyms to 0: now eoftoken is created just like the others.
665 * src/print.c (print_grammar): Don't special case the eof token.
666 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
667 lie anyway, albeit pleasant.
668 * tests/calc.at: Exercise error messages with eoftoken.
669 Change the grammar so that empty input is invalid.
670 Adjust expectations.
671 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
672
673 2001-12-27 Akim Demaille <akim@epita.fr>
674
675 * configure.in: Check the protos of strchr ans strspn.
676 Replace strchr if needed.
677 * src/system.h: Provide the protos of strchr, strspn and memchr if
678 missing.
679 * lib/strchr.c: New.
680 * src/reader.c (symbols_save): Use strchr.
681
682 2001-12-27 Akim Demaille <akim@epita.fr>
683
684 * src/print.c, src/print_graph.c (escape): New.
685 Use it to quote the TAGS outputs.
686 * src/print_graph.c (print_state): Now errors are in red, and
687 reductions in green.
688 Prefer high to wide: output the state number on a line of its own.
689
690 2001-12-27 Akim Demaille <akim@epita.fr>
691
692 * src/state.h, src/state.c (reductions_new): New.
693 * src/LR0.c (set_state_table): Let all the states have a
694 `reductions', even if reduced to 0.
695 (save_reductions): Adjust.
696 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
697 * src/print.c (print_reductions, print_actions): Adjust.
698 * src/output.c (action_row): Adjust.
699

712
713 2001-12-27 Akim Demaille <akim@epita.fr>
714
715 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
716 * src/print.c: here.
717 (lookaheadset, shiftset): New, used as additional storage by
718 print_reductions.
719 (print_results): Adjust.
720 (print_shifts, print_gotos, print_errs): New, extracted from...
721 (print_actions): here.
722 * src/print_graph.c (print_actions): Remove dead code.
723
724 2001-12-27 Akim Demaille <akim@epita.fr>
725
726 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
727 `$n' and `@n'.
728
729 2001-12-27 Akim Demaille <akim@epita.fr>
730
731 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
732 (build_relations): Adjust.
733
734 2001-12-27 Akim Demaille <akim@epita.fr>
735
736 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
737 duplication.
738
739 2001-12-27 Akim Demaille <akim@epita.fr>
740
741 * src/reader.c (packgram): Catch nitems overflows.
742
743 2001-12-27 Akim Demaille <akim@epita.fr>
744
745 * src/files.c, src/files.h (guard_obstack): Remove.
746 * src/output.c (output): Adjust.
747 * src/reader.c (parse_braces): New, factoring...
748 (copy_action, copy_guard): these two which are renamed as...
749 (parse_action, parse_guard): these.
750 As a voluntary consequence, using braces around guards is now
751 mandatory.
752
753 2001-12-27 Akim Demaille <akim@epita.fr>
754
755 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
756 * src/reader.c (symbol_list): `guard' and `guard_line' are new
757 members.
758 (symbol_list_new): Adjust.
759 (copy_action): action_line is the first line, not the last.
760 (copy_guard): Just as for actions, store the `action' only, not
761 the switch/case/break flesh.
762 Don't parse the user action that might follow the guard, let...
763 (readgram): do it, i.e., now, there can be an action after a
764 guard.
765 In other words the guard is just explicitly optional.
766 (packgram): Adjust.
767 * src/output.c (guards_output): New.
768 (output_parser): Call it when needed.
769 (output): Also free the guard and attrs obstacks.
770 * src/files.c, src/files.h (obstack_save): Remove.
771 (output_files): Remove.
772 As a result, if one needs the former `.act' file, using an
773 appropriate skeleton which requires actions and guards is now
774 required.
775 * src/main.c (main): Adjust.
776 * tests/semantic.at: New.
777 * tests/regression.at: Use `input.y' as input file name.
778 Avoid 8+3 problems by requiring input.c when the test needs the
779 parser.
780
781 2001-12-27 Akim Demaille <akim@epita.fr>
782
783 * src/reader.c (symbol_list_new): Be sure to initialize all the
784 fields.
785
786 2001-12-27 Akim Demaille <akim@epita.fr>
787
788 All the hacks using a final pseudo state are now useless.
789
790 * src/LR0.c (set_state_table): state_table holds exactly nstates.
791 * src/lalr.c (nLA): New.
792 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
793 instead of lookaheadsp from the pseudo state (nstate + 1).
794
795 2001-12-27 Akim Demaille <akim@epita.fr>
796
797 * src/output.c (action_row, token_actions): Use a state_t instead
798 of a integer, and nlookaheads instead of the following state's
799 lookaheadsp.
800
801 2001-12-27 Akim Demaille <akim@epita.fr>
802
803 * src/conflicts.c (log_resolution, flush_shift)
804 (resolve_sr_conflict, set_conflicts, solve_conflicts)
805 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
806 (conflicts_print, print_reductions): Use a state_t instead of an
807 integer when referring to a state.
808 As much as possible, depend upon nlookaheads, instead of the
809 `lookaheadsp' member of the following state (since lookaheads of
810 successive states are successive, the difference between state n + 1
811 and n served as the number of lookaheads for state n).
812 * src/lalr.c (add_lookback_edge): Likewise.
813 * src/print.c (print_core, print_actions, print_state)
814 (print_results): Likewise.
815 * src/print_graph.c (print_core, print_actions, print_state)
816 (print_graph): Likewise.
817 * src/conflicts.h: Adjust.
818
819 2001-12-27 Akim Demaille <akim@epita.fr>
820
821 * src/bison.hairy: Formatting/comment changes.
822 ANSIfy.
823 Remove `register' indications.
824 Add plenty of `static'.
825
826 2001-12-27 Akim Demaille <akim@epita.fr>
827
828 * src/output.c (prepare): Drop the muscle `ntbase' which
829 duplicates ntokens.
830 * src/bison.simple: Formatting/comment changes.
831 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
832 is an undocumented synonym.
833
834 2001-12-22 Akim Demaille <akim@epita.fr>
835
836 * src/output.c (output_table_data): Change the prototype to use
837 `int' for array ranges: some invocations do pass an int, not a
838 short.
839 Reported by Wayne Green.
840
841 2001-12-22 Akim Demaille <akim@epita.fr>
842
843 Some actions of web2c.y are improperly triggered.
844 Reported by Mike Castle.
845
846 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
847 * tests/regression.at (Web2c): Rename as...
848 (Web2c Report): this.
849 (Web2c Actions): New.
850
851 2001-12-22 Akim Demaille <akim@epita.fr>
852
853 Reductions in web2c.y are improperly reported.
854 Reported by Mike Castle.
855
856 * src/conflicts.c (print_reductions): Fix.
857 * tests/regression.at (Web2c): New.
858
859 2001-12-18 Akim Demaille <akim@epita.fr>
860
861 Some host fail on `assert (!"foo")', which expands to
862 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
863 Reported by Nelson Beebee.
864
865 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
866 `#define it_succeeded 0' and `assert (it_succeeded)'.
867
868 2001-12-17 Marc Autret <autret_m@epita.fr>
869
870 * src/bison.simple: Don't hard code the skeleton line and filename.
871 * src/output.c (output_parser): Rename 'line' as 'output_line'.
872 New line counter 'skeleton_line' (skeleton-line muscle).
873
874 2001-12-17 Paul Eggert <eggert@twinsun.com>
875
876 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
877 YYDEBUG must be defined to a nonzero value.
878
879 * src/bison.simple (yytname): Do not assume that the user defines
880 YYDEBUG to a properly parenthesized expression.
881
882 2001-12-17 Akim Demaille <akim@epita.fr>
883
884 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
885 nlookaheads is a new member.
886 Adjust all users.
887 * src/lalr.h (nlookaheads): Remove this orphan declaration.
888 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
889 state.
890
891 2001-12-17 Akim Demaille <akim@epita.fr>
892
893 * src/files.h, src/files.c (open_files, close_files): Remove.
894 * src/main.c (main): Don't open/close files, nor invoke lex_free,
895 let...
896 * src/reader.c (reader): Do it.
897
898 2001-12-17 Akim Demaille <akim@epita.fr>
899

909
910 * src/output.c (output_obstack): Be static and rename as...
911 (format_obstack): this, to avoid any confusion with files.c's
912 output_obstack.
913 * src/reader.h (muscle_obstack): Move to...
914 * src/output.h: here, since it's defined in output.c.
915
916 2001-12-17 Akim Demaille <akim@epita.fr>
917
918 * src/output.c (action_row, save_column, default_goto)
919 (sort_actions, matching_state, pack_vector): Better variable
920 locality.
921
922 2001-12-17 Akim Demaille <akim@epita.fr>
923
924 * src/output.c: Various formatting changes.
925
926 2001-12-17 Akim Demaille <akim@epita.fr>
927
928 * src/files.c (output_files): Free the output_obstack.
929 * src/main.c (main): Call print and print_graph conditionally.
930 * src/print.c (print): Work unconditionally.
931 * src/print_graph.c (print_graph): Work unconditionally.
932 * src/conflicts.c (log_resolution): Output only if verbose_flag.
933
934 2001-12-16 Marc Autret <autret_m@epita.fr>

936 * src/output.c (actions_output): Fix. When we use %no-lines,
937 there is one less line per action.
938
939 2001-12-16 Marc Autret <autret_m@epita.fr>
940
941 * src/bison.simple: Remove a useless #line directive.
942 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
943 * src/output.c (get_lines_number): New.
944 (output_parser): Adjust, now takes care about the lines of a
945 output muscles.
946 Fix line numbering.
947 (actions_output): Computes the number of lines taken by actions.
948 (output_master_parser): Insert new skeleton which is the name of
949 the output parser file name.
950
951 2001-12-15 Marc Autret <autret_m@epita.fr>
952
953 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
954
955 2001-12-15 Marc Autret <autret_m@epita.fr>
956
957 * src/output.c (output_gram): Keep track of the hairy one.
958
959 2001-12-15 Akim Demaille <akim@epita.fr>
960
961 Make `make distcheck' work.
962
963 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
964 system.h which uses libgettext.h.
965
966 2001-12-15 Akim Demaille <akim@epita.fr>
967
968 * src/nullable.c (set_nullable): Useless rules must be skipped,
969 otherwise, since we range over their symbols, we might look at a
970 nonterminal which no longer ``exists'', i.e., it is not counted in
971 `nvars', hence we overflow our arrays.
972
973 2001-12-15 Akim Demaille <akim@epita.fr>
974
975 The header can also be produced directly, without any obstack!
976 Yahoo!
977
978 * src/files.c, src/files.h (defines_obstack): Remove.
979 (compute_header_macro): Global.
980 (defines_obstack_save): Remove.
981 * src/reader.c (parse_union_decl): No longer output to
982 defines_obstack: its content can be found in the `stype' muscle
983 anyway.
984 (output_token_translations): Merge into...
985 (symbols_output): this.
986 Rename as...
987 (symbols_save): this.
988 (reader): Adjust.
989 * src/output.c (header_output): New.
990 (output): Call it.
991
992 2001-12-15 Akim Demaille <akim@epita.fr>
993
994 * src/reader.c (parse_union_decl): Instead of handling two obstack
995 simultaneously, use one to define the `stype' muscle, and use the
996 value of the latter to fill defines_obstack.
997 (copy_comment): Remove.
998 (copy_comment2): Work for a single obstack.
999 Rename as...
1000 (copy_comment): this.
1001
1002 2001-12-15 Akim Demaille <akim@epita.fr>
1003
1004 * src/lex.c, src/lex.h (xgetc): No longer static.
1005 * src/reader.c (parse_union_decl): Revamp.
1006
1007 2001-12-15 Akim Demaille <akim@epita.fr>
1008
1009 Still making progress in separating Bison into (i) input, (ii)
1010 process, (iii) output: now we can directly output the parser file
1011 without using table_obstack at all.
1012
1013 * src/files.c, src/files.h (table_obstack): Bye bye.
1014 (parser_file_name): New.
1015 * src/files.c (compute_output_file_names): Compute it.
1016 * src/output.c (actions_output, output_parser)
1017 (output_master_parser): To a file instead of an obstack.
1018
1019 2001-12-15 Akim Demaille <akim@epita.fr>
1020
1021 Attach actions to rules, instead of pre-outputting them to
1022 actions_obstack.
1023
1024 * src/gram.h (rule_t): action and action_line are new members.
1025 * src/reader.c (symbol_list): Likewise.
1026 (copy_action): Save the actions within the rule.
1027 (packgram): Save them in rule_table.
1028 * src/output.c (actions_output): New.
1029 (output_parser): Use it on `%%actions'.
1030 (output_rule_data): Don't free rule_table.
1031 (output): Do it.
1032 (prepare): Don't save the `action' muscle.
1033 * src/bison.simple: s/%%action/%%actions/.
1034
1035 2001-12-15 Akim Demaille <akim@epita.fr>
1036
1037 * src/reader.c (copy_action): When --yacc, don't append a `;'
1038 to the user action: let it fail if lacking.
1039 Suggested by Arnold Robbins and Tom Tromey.
1040
1041 2001-12-14 Akim Demaille <akim@epita.fr>
1042
1043 * src/lex.c (literalchar): Simply return the char you decoded, non
1044 longer mess around with obstacks and int pointers.
1045 Adjust all callers.
1046
1047 2001-12-14 Akim Demaille <akim@epita.fr>
1048
1049 * src/lex.c (literalchar): Don't escape the special characters,
1050 just decode them, and keep them as char (before, eol was output as
1051 the 2 char string `\n' etc.).
1052 * src/output.c (output_rule_data): Use quotearg to output the
1053 token strings.
1054
1055 2001-12-13 Paul Eggert <eggert@twinsun.com>
1056
1057 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1058 Do not infringe on the global user namespace when using C++.
1059 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1060 All uses of `fprintf' and `stderr' changed.
1061
1062 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1063
1064 2001-12-13 Akim Demaille <akim@epita.fr>
1065
1066 The computation of nullable is broken: it doesn't handle empty
1067 RHS's properly.
1068
1069 * tests/torture.at (GNU AWK Grammar): New.
1070 * tests/sets.at (Nullable): New.
1071 * src/nullable.c (set_nullable): Instead of blindly looping over
1072 `ritems', loop over the rules, and then over their rhs's.
1073
1074 Work around Autotest bugs.
1075
1076 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1077 frame, because Autotest understand lines starting with a `+' as
1078 traces from the shell. Then, they are not processed properly.
1079 Admittedly an Autotest bug, but we don't have time to wait for
1080 Autotest to catch up.
1081 * tests/regression.at (Broken Closure): Adjust to the new table
1082 frames.
1083 Move to...
1084 * tests/sets.at: here.
1085
1086 2001-12-13 Akim Demaille <akim@epita.fr>
1087
1088 * src/closure.c (closure): Use nrules instead of playing tricks
1089 with BITS_PER_WORD.
1090
1091 2001-12-13 Akim Demaille <akim@epita.fr>
1092
1093 * src/print.c (print_actions): Output the handling of `$' as the
1094 traces do: shifting the token EOF. Before EOF was treated as a
1095 nonterminal.
1096 * tests/regression.at: Adjust some tests.
1097 * src/print_graph.c (print_core): Complete the set of items via
1098 closure. The next-to-final and final states are still unsatisfying,
1099 but that's to be addressed elsewhere.
1100 No longer output the rule numbers, but do output the state number.
1101 A single loop for the shifts + gotos is enough, but picked a
1102 distinct color for each.
1103 (print_graph): Initialize and finalize closure.
1104
1105 2001-12-13 Akim Demaille <akim@epita.fr>
1106
1107 * src/reader.c (readgram): Remove dead code, an strip useless
1108 braces.
1109 (get_type): Remove, unused.
1110
1111 2001-12-12 Akim Demaille <akim@epita.fr>
1112
1113 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1114 on that of lib/error.c.
1115
1116 2001-12-12 Akim Demaille <akim@epita.fr>
1117
1118 Some hosts don't like `/' in includes.
1119
1120 * src/system.h: Include libgettext.h without qualifying the path.
1121 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1122 $(top_srcdir).
1123
1124 2001-12-11 Marc Autret <autret_m@epita.fr>
1125
1126 * src/output.c (output_parser): Remove useless muscle.
1127
1128 2001-12-11 Marc Autret <autret_m@epita.fr>
1129
1130 * src/bison.simple: Remove #line just before %%epilogue. It
1131 is now handled in ...
1132 * src/reader.c (read_additionnal_code): Add the output of a
1133 #line for the epilogue.
1134
1135 2001-12-10 Marc Autret <autret_m@epita.fr>
1136
1137 * src/reader.c (copy_definition): Re-use CPP-outed code which
1138 replace precedent remove.
1139 * src/bison.simple: Remove #line before %%prologue because
1140 %%input-line is wrong at this time.
1141
1142 2001-12-10 Marc Autret <autret_m@epita.fr>
1143
1144 * src/reader.c (symbols_output): Clean up.
1145 * src/output.c (output_gram, output): Clean up.
1146
1147 2001-12-10 Akim Demaille <akim@epita.fr>
1148
1149 * src/lalr.c (initialize_lookaheads): New. Extracted from...
1150 * src/LR0.c (set_state_table): here.
1151 * src/lalr.c (lalr): Call it.
1152
1153 2001-12-10 Akim Demaille <akim@epita.fr>
1154
1155 * src/state.h (shifts): Remove the `number' member: shifts are
1156 attached to state, hence no longer need to be labelled with a
1157 state number.
1158
1159 2001-12-10 Akim Demaille <akim@epita.fr>
1160
1161 Now that states have a complete set of members, the linked list of
1162 shifts is useless: just fill directly the state's shifts member.
1163
1164 * src/state.h (shifts): Remove the `next' member.
1165 * src/LR0.c (first_state, last_state): Remove.
1166 Adjust the callers.
1167 (augment_automaton): Don't look for the shifts that must be added
1168 a shift on EOF: it is those of the state we looked for! But now,
1169 since shifts are attached, it is no longer needed to looking
1170 merely by its id: its number.
1171
1172 2001-12-10 Akim Demaille <akim@epita.fr>
1173
1174 * src/LR0.c (augment_automaton): Better variable locality.
1175 Remove an impossible branch: if there is a state corresponding to
1176 the start symbol being shifted, then there is shift for the start
1177 symbol from the initial state.
1178
1179 2001-12-10 Akim Demaille <akim@epita.fr>
1180
1181 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1182 only when appropriate: when insert_start_shifting_state' is not
1183 invoked.
1184 * tests/regression.at (Rule Line Numbers): Adjust.
1185
1186 2001-12-10 Akim Demaille <akim@epita.fr>
1187
1188 * src/LR0.c (augment_automaton): Now that all states have shifts,
1189 merge the two cases addition shifts to the initial state.
1190
1191 2001-12-10 Akim Demaille <akim@epita.fr>
1192
1193 * src/lalr.c (set_state_table): Move to...
1194 * src/LR0.c: here.
1195 * src/lalr.c (lalr): Don't call it...
1196 * src/LR0.c (generate_states): do it.
1197 * src/LR0.h (first_state): Remove, only the table is used.
1198
1199 2001-12-10 Akim Demaille <akim@epita.fr>
1200
1201 * src/LR0.h (first_shift, first_reduction): Remove.
1202 * src/lalr.c: Don't use first_shift: find shifts through the
1203 states.
1204
1205 2001-12-10 Akim Demaille <akim@epita.fr>
1206
1207 * src/LR0.c: Attach shifts to states as soon as they are
1208 computed.
1209 * src/lalr.c (set_state_table): Instead of assigning shifts to
1210 state, just assert that the mapping was properly done.
1211
1212 2001-12-10 Akim Demaille <akim@epita.fr>
1213
1214 * src/LR0.c (insert_start_shift): Rename as...
1215 (insert_start_shifting_state): this.
1216 (insert_eof_shifting_state, insert_accepting_state): New.
1217 (augment_automaton): Adjust.
1218 Better locality of the variables.
1219 When looking if the start_symbol is shifted from the initial
1220 state, using `while (... symbol != start_symbol ...)' sounds
1221 better than `while (... symbol < start_symbol ...)': If fail
1222 to see how the order between symbols could be relevant!
1223
1224 2001-12-10 Akim Demaille <akim@epita.fr>
1225
1226 * src/getargs.h: Don't declare `spec_name_prefix' and
1227 `spec_file_prefix', declared by src/files.h.
1228 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1229 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1230 * src/output.c (prepare): Adjust.
1231 * src/reader.c (symbols_output): Likewise.
1232 * src/vmsgetargs.c: Vaguely adjust, but who cares?
1233
1234 2001-12-10 Akim Demaille <akim@epita.fr>
1235
1236 * src/muscle_tab.c (muscle_init): NULL is a better default than
1237 `"0"'.
1238
1239 2001-12-10 Akim Demaille <akim@epita.fr>
1240
1241 * src/reader.c (reader): Calling symbols_output once is enough.
1242
1243 2001-12-10 Akim Demaille <akim@epita.fr>
1244
1245 Now that states have a complete set of members, the linked list of
1246 reductions is useless: just fill directly the state's reductions
1247 member.
1248
1249 * src/state.h (struct reductions): Remove member `number' and
1250 `next'.
1251 * src/LR0.c (first_reduction, last_reduction): Remove.
1252 (save_reductions): Don't link the new reductions, store them in
1253 this_state.
1254 * src/lalr.c (set_state_table): No need to attach reductions to
1255 states, it's already done.
1256 * src/output.c (output_actions): No longer free the shifts, then
1257 the reductions, then the states: free all the states and their
1258 members.
1259
1260 2001-12-10 Akim Demaille <akim@epita.fr>
1261
1262 * src/options.c (OPTN, DRTV, BOTH): New.
1263 (option_table): Use them.
1264
1265 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1266 the job of system.h.
1267 * src/options.c: Don't include stdio.h and xalloc.h for the same
1268 reasons.
1269
1270 2001-12-10 Akim Demaille <akim@epita.fr>
1271
1272 * src/output.c (output, prepare): Make sure the values of the
1273 muscles `action' and `prologue' are 0-terminated.
1274
1275 2001-12-10 Akim Demaille <akim@epita.fr>
1276
1277 Clean up GCC warnings.
1278
1279 * src/reader.c (copy_action): `buf' is not used.
1280 (parse_skel_decl): Be static.
1281 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1282 * src/options.h (create_long_option_table): Have a real prototype.
1283 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1284 (hash_delete_at): Return const void *.
1285 Adjust casts to preserve the const.
1286
1287 2001-12-10 Akim Demaille <akim@epita.fr>
1288
1289 * configure.in: Require 2.52g.
1290 M4 is not needed, but AUTOM4TE is.
1291 * m4/m4.m4: Remove.
1292 * tests/Makefile.am: Adjust.
1293
1294 2001-12-10 Akim Demaille <akim@epita.fr>
1295
1296 One structure for states is enough, even though theoretically
1297 there are LR(0) states and LALR(1) states.
1298
1299 * src/lalr.h (state_t): Remove.
1300 (state_table): Be state_t **, not state_t *.
1301 * src/state.h (core, CORE_ALLOC): Rename as...
1302 (state_t, STATE_ALLOC): this.
1303 Add the LALR(1) members: shifts, reductions, errs.
1304 * src/LR0.c (state_table): Rename as...
1305 (state_hash): this, to avoid name clashes with the global
1306 `state_table'.
1307 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1308 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1309
1310 2001-12-10 Akim Demaille <akim@epita.fr>
1311
1312 Bison dumps core on bash.y.
1313 Reported by Pascal Bart.
1314
1315 * src/warshall.c (bitmatrix_print): New.
1316 (TC): Use it.
1317 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1318 j must be the outer loop.
1319 * tests/regression.at (Broken Closure): New.
1320
1321 2001-12-05 Akim Demaille <akim@epita.fr>
1322
1323 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1324 its argument.
1325 Reported by Peter Hámorský.
1326
1327 2001-12-05 Akim Demaille <akim@epita.fr>
1328
1329 * src/conflicts.c (err_table): Remove.
1330 (resolve_sr_conflict): Adjust.
1331 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1332 Rename as...
1333 (state_t.reductions, state_t.shifts): this.
1334
1335 2001-12-05 Akim Demaille <akim@epita.fr>
1336
1337 * src/reduce.c (reduce_grammar_tables): No longer disable the
1338 removal of useless rules via CPP but via `if (0)', so that the
1339 compiler still check the code is valid.
1340 For instance, it should have noticed `rline' no longer exists: use
1341 the `line' member of rule_t.
1342 * src/gram.c (dummy, rline): Remove, unused.
1343
1344 2001-12-05 Akim Demaille <akim@epita.fr>
1345
1346 * src/output.c (pack_vector): Use assert, not berror.
1347 * src/main.c (berror): Remove, unused.
1348
1349 2001-12-05 Akim Demaille <akim@epita.fr>
1350
1351 New experimental feature: if --verbose --trace output all the
1352 items of a state, not only its kernel.
1353
1354 * src/print.c (print_core): If `trace_flag', then invoke closure
1355 before outputting the items of the state (print_core is no longer
1356 a correct name them).
1357 (print_results): Invoke new_closure/free_closure if needed.
1358
1359 2001-12-05 Akim Demaille <akim@epita.fr>
1360
1361 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1362 * src/closure.c, src/closure.h (itemsetsize): Rename as...
1363 (nitemset): for consistency with the rest of the project.
1364
1365 2001-12-05 Akim Demaille <akim@epita.fr>
1366
1367 * src/closure.c (print_closure): Improve.
1368 (closure): Use it for printing input and output.
1369
1370 2001-12-05 Akim Demaille <akim@epita.fr>
1371
1372 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1373 indexed by nonterminals.
1374
1375 2001-12-05 Akim Demaille <akim@epita.fr>
1376
1377 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1378 what it was!).
1379 * src/warshall.h: Remove accidental duplication of the content.
1380
1381 2001-12-05 Akim Demaille <akim@epita.fr>
1382
1383 * src/closure.c (set_fderives): De-obfuscate.
1384
1385 2001-12-05 Akim Demaille <akim@epita.fr>
1386
1387 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1388
1389 2001-12-05 Akim Demaille <akim@epita.fr>
1390
1391 * src/closure.c (set_firsts): De-obfuscate.
1392
1393 2001-12-05 Akim Demaille <akim@epita.fr>
1394
1395 * src/output.c (action_row): De-obfuscate
1396 using the good o' techniques: arrays not pointers, variable
1397 locality, BITISSET, RESETBIT etc.
1398
1399 2001-12-05 Akim Demaille <akim@epita.fr>
1400
1401 Pessimize the code to simplify it: from now on, all the states
1402 have a valid SHIFTS, which NSHIFTS is possibly 0.
1403
1404 * src/LR0.c (shifts_new): Be global and move to..
1405 * src/state.c, src/state.h: here.
1406 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1407 * src/print_graph: Adjust.
1408
1409 2001-12-05 Akim Demaille <akim@epita.fr>
1410
1411 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1412 * src/conflicts.c: Use it.
1413 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1414 incorrectly ``simplified''.
1415

1417
1418 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

1428
1429 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1430 (print_reductions): De-obfuscate using the good o' techniques:

1465
1466 * src/lalr.c (matrix_print): New.
1467 (transpose): Use it.
1468 Use arrays instead of pointers.
1469
1470 2001-12-05 Akim Demaille <akim@epita.fr>
1471
1472 * src/lalr.c (maxrhs): Move to...
1473 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1474 * src/lalr.c (build_relations): Adjust.
1475
1476 2001-12-05 Akim Demaille <akim@epita.fr>
1477
1478 * src/lalr.c (transpose): Free the memory allocated to the
1479 argument, as it is replaced by the results by the unique caller.
1480 (build_relations): Merely invoke transpose: it handles the memory
1481 deallocation.
1482 Improve variable locality.
1483 Avoid variables used as mere abbreviations.
1484 (compute_lookaheads): Use arrays instead of pointers.
1485

1500 * src/lalr.c (traverse): Use arrays instead of pointers.
1501
1502 2001-12-05 Akim Demaille <akim@epita.fr>
1503
1504 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1505 the handling of squeue.
1506 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1507
1508 2001-12-05 Akim Demaille <akim@epita.fr>
1509
1510 Because useless nonterminals are now kept alive (instead of being
1511 `destroyed'), we now sometimes examine them, and store information
1512 related to them. Hence we need to know their number, and adjust
1513 memory allocations.
1514
1515 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1516 static.
1517 * src/LR0.c (allocate_itemsets): The memory allocated to
1518 `symbol_count' was used for two different purpose: once to count
1519 the number of occurrences of each symbol, and later reassigned to
1520 `shift_symbol', containing the symbol that can be shifted from a
1521 given state.
1522 Deobfuscate, i.e., allocate, use and free `symbol_count' here
1523 only, and...
1524 (new_itemsets): Allocate `shift_symbol' here.
1525 (allocate_itemsets): symbol_count includes useless nonterminals.
1526 Make room for them.
1527 (free_storage): Use `free', not `XFREE', for pointers that cannot
1528 be null.
1529
1530 2001-12-05 Akim Demaille <akim@epita.fr>
1531
1532 * src/nullable.c (set_nullable): Deobfuscate the handling of
1533 ritem.
1534 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1535
1536 2001-12-05 Akim Demaille <akim@epita.fr>
1537
1538 * src/gram.c, src/gram.h (ritem_print): New.
1539 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1540 (This useless function was defined only to work around VMS linkers
1541 that can't handle compilation units with variables only).
1542 * src/reduce.c (dump_grammar): Use it to trace the construction of
1543 ritem.
1544
1545 2001-12-04 Paul Eggert <eggert@twinsun.com>
1546
1547 * src/bison.simple (union yyalloc): Change member names
1548 to be the same as the stack names.
1549 (yyparse): yyptr is now union yyalloc *, not char *.
1550 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
1551 and may generate better code on some machines.
1552 (yystpcpy): Use prototype if __STDC__ is defined, not just
1553 if __cplusplus is defined.
1554
1555 2001-11-30 Akim Demaille <akim@epita.fr>
1556
1557 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1558 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1559 Gettext doesn't compile cleanly, and dies with -Werror.
1560 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1561 Include WARNING_CFLAGS here.
1562 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1563 before being defined.
1564
1565 2001-11-27 Paul Eggert <eggert@twinsun.com>
1566
1567 * lib/quotearg.h (quotearg_n, quotearg_n_style):
1568 First arg is int, not unsigned.

1570 (SIZE_MAX, UINT_MAX): New macros.
1571 (quotearg_n_options): Abort if N is negative.
1572 Avoid overflow check on hosts where size_t is 64 bits and int
1573 is 32 bits, as overflow is impossible there.
1574 Fix off-by-one typo that caused unnecessary reallocation.
1575
1576 2001-11-29 Paul Eggert <eggert@twinsun.com>
1577

1579
1580 * doc/bison.texinfo (Bison Parser): Discuss system headers

1583 * src/bison.simple:
1584 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1585 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1586 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1587
1588 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
1589 on user names when possible.
1590
1591 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1592 Simplify test for whather <alloca.h> exists.
1593
1594 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1595
1596 (<stdio.h>): Include if YYDEBUG.
1597
1598 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
1599 ! defined (yyoverflow) && ! defined (yymemcpy).
1600
1601 (yymemcpy, yyparse): Rename local variables as needed so that
1602 they all begin with 'yy'.
1603
1604 (yystrlen, yystpcpy): New functions.
1605
1606 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1607 All uses changed.
1608
1609 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
1610 instead of relying on string.h functions. Use YYSTACK_ALLOC
1611 and YYSTACK_FREE instead of malloc and free.
1612
1613 2001-11-30 Akim Demaille <akim@epita.fr>

1622
1623 2001-11-30 Akim Demaille <akim@epita.fr>
1624
1625 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1626 if body instead of `;' to pacify GCC's warnings.
1627
1628 2001-11-30 Akim Demaille <akim@epita.fr>
1629
1630 Instead of mapping the LHS of unused rules to -1, keep the LHS
1631 valid, but flag the rules as invalid.
1632
1633 * src/gram.h (rule_t): `useful' is a new member.
1634 * src/print.c (print_grammar): Adjust.
1635 * src/derives.c (set_derives): Likewise.
1636 * src/reader.c (packgram, reduce_output): Likewise.

1639
1640 2001-11-30 Akim Demaille <akim@epita.fr>

1646
1647 2001-11-30 Akim Demaille <akim@epita.fr>
1648
1649 * src/reduce.c (nonterminals_reduce): Instead of throwing away
1650 useless nonterminals, move them at the end of the symbol arrays.
1651 (reduce_output): Adjust.
1652 * tests/reduce.at (Useless Nonterminals): Adjust.
1653
1654 2001-11-30 Akim Demaille <akim@epita.fr>

1664 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1665 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1666 New macros.
1667 (union yyalloc): New type.
1668 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1669 an arbitrary restriction on hosts where size_t is wider than int.
1670
1671 (yyparse): Don't dump core if alloca or malloc fails; instead, report
1672 a parser stack overflow. Allocate just one block of memory for all
1673 three stacks, instead of allocating three blocks; this typically is
1674 faster and reduces fragmentation.
1675
1676 Do not limit the number of items in the stack to a value that fits
1677 in 'int', as this is an arbitrary limit on hosts with 64-bit
1678 size_t and 32-bit int.
1679
1680 2001-11-29 Marc Autret <autret_m@epita.fr>

2110 use abs. path to find config.h.
2111 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

3511
3512 2001-01-19 Akim Demaille <akim@epita.fr>
3513
3514 * src/lex.h: Rename all the tokens:
3515 s/\bENDFILE\b/tok_eof/g;

3534 instead of returning a token.
3535 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3536 * src/reader.c (read_declarations): Adjust.
3537 * src/files.c (open_files): Don't call `compute_base_names', don't
3538 compute `attrsfile' since they depend upon data which might be
3539 *in* the input file now.
3540 (output_files): Do it here.
3541 * src/output.c (output_headers): Document the fact that this patch
3542 introduces a guaranteed SEGV for semantic parsers.
3543 * doc/bison.texinfo: Document them.
3544 * tests/suite.at: Exercise these %options.

3564
3565 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

3568
3569 2000-12-20 Akim Demaille <akim@epita.fr>
3570
3571 * src/files.c (open_files): Actually the `.output' file is based

3601 (stringappend): Be just like strcat but allocate.
3602 (base_names): Eve out from open_files.
3603 Try to simplify the rather hairy computation of base_name and
3604 short_base_name.
3605 (open_files): Use it.
3606 * tests/suite.at (Checking output file names): New test.
3607

3643
3644 2000-12-19 Akim Demaille <akim@epita.fr>
3645
3646 * src/files.c (open_files): Yipee! We no longer need all the code

3648
3649 2000-12-19 Akim Demaille <akim@epita.fr>
3650

3680 prevents type checking.
3681 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

3731 Qualify it `const'.
3732 (obstack_copy, obstack_copy0): Rename the second argument as

3762 (done): Rename as...
3763 (output_files): this.
3764 Use `obstack_save'.
3765 * src/main.c (main): Don't use `atexit' to register `done', since
3766 it no longer has to remove tmp files, just call `output_files'
3767 when there are no errors.
3768
3769 2000-11-02 Akim Demaille <akim@epita.fr>
3770

3834 * src/reader.c (copy_dollar): Likewise.
3835
3836 2000-10-16 Akim Demaille <akim@epita.fr>
3837
3838 * src/reader.c (copy_comment2): Expect the input stream to be on
3839 the `/' which is suspected to open a comment, instead of being
3840 called after `//' or `/*' was read.
3841 (copy_comment, copy_definition, parse_union_decl, copy_action)
3842 (copy_guard): Adjust.
3843
3844 2000-10-16 Akim Demaille <akim@epita.fr>

3869
3870 2000-10-04 Akim Demaille <akim@epita.fr>
3871
3872 When a literal string is used to define two different tokens,
3873 `bison -v' segfaults.

3882
3883 * src/reader.c (parse_expect_decl): Keep `count' within the size
3884 of `buffer'.
3885 From Neil Booth.
3886
3887 2000-10-02 Paul Eggert <eggert@twinsun.com>
3888
3889 * bison.s1 (yyparse): Assign the default value
3890 unconditionally, to avoid a GCC warning and make the parser a
3891 tad smaller.
3892
3893 2000-10-02 Akim Demaille <akim@epita.fr>
3894
3895 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3896 options.
3897
3898 2000-10-02 Akim Demaille <akim@epita.fr>
3899
3900 * src/derives.c, src/print.c, src/reduce.c: To ease the
3901 translation, move some `\n' out of the translated strings.
3902
3903 2000-10-02 Akim Demaille <akim@epita.fr>
3904
3905 The location tracking mechanism is precious for parse error
3906 messages. Nevertheless, it is enabled only when `@n' is used in
3907 the grammar, which is a different issue (you can use it in error
3908 message, but not in the grammar per se). Therefore, there should
3909 be another means to enable it.
3910
3911 * src/getargs.c (getargs): Support `--locations'.
3912 (usage): Report it.
3913 * src/getargs.h (locationsflag): Export it.
3914 * src/lex.c (percent_table): Support `%locations'.
3915 * src/reader.c (yylsp_needed): Remove this variable, now replaced
3916 with `locationsflag'.
3917 * doc/bison.texinfo: Document `--locations' and `%locations'.
3918 Sort the options.
3919 * tests/calc.m4: Test it.
3920
3921 For regularity of the names, replace each
3922 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
3923 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
3924 In addition replace each `flag' with `_flag'.
3925
3926 2000-10-02 Akim Demaille <akim@epita.fr>
3927
3928 Also test parse error messages, including with YYERROR_VERBOSE.
3929
3930 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
3931 associative).
3932 Use it to check the computations.
3933 Use it to check `nonassoc' is honored.
3934 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
3935 `--yyerror-verbose'.
3936 (_AT_CHECK_CALC): Adjust to this option.
3937 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3938
3939 2000-10-02 Akim Demaille <akim@epita.fr>
3940
3941 Test also `--verbose', `--defines' and `--name-prefix'. Testing
3942 the latter demonstrates a flaw in the handling of non debugging
3943 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
3944 was used in order to simplify:
3945
3946 #if YYDEBUG
3947 if (yydebug)
3948 {
3949 ...
3950 }
3951 #endif
3952
3953 into
3954
3955 if (yydebug)
3956 {
3957 ...
3958 }
3959
3960 unfortunately this leads to a CPP conflict when
3961 `--name-prefix=foo' is used since it produces `#define yydebug
3962 foodebug'.
3963
3964 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3965 (YYDPRINTF): New macro.
3966 Spread its use.
3967 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3968 the bison options.
3969 Also test `--verbose', `--defines' and `--name-prefix'.
3970
3971 2000-10-02 Akim Demaille <akim@epita.fr>
3972
3973 Improve the readability of the produced parsers.
3974
3975 * src/bison.s1: Formatting changes.
3976 Improve the comment related to the `$' mark.
3977 (yydefault): Don't fall through to `yyresume': `goto' there.
3978 * src/output.c (output_parser): When the `$' is met, skip the end
3979 of its line.
3980 New variable, `number_of_dollar_signs', to check there's exactly
3981 one `$' in the parser skeleton.
3982
3983 2000-10-02 Akim Demaille <akim@epita.fr>
3984
3985 * lib/xstrdup.c: New file, from the fileutils.
3986 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
3987 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
3988 instead of strlen + xmalloc + strcpy.
3989 * src/symtab.c (copys): Remove, use xstrdup instead.
3990
3991 2000-10-02 Akim Demaille <akim@epita.fr>
3992
3993 * src/gram.h (associativity): New enum type which replaces the
3994 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
3995 `right_assoc', `left_assoc' and `non_assoc'.
3996 Adjust all dependencies.
3997 * src/reader.c: Formatting changes.
3998 (LTYPESTR): Don't define it, use it as a literal in
3999 `reader_output_yylsp'.
4000 * src/symtab.h (symbol_class): New enum type which replaces the
4001 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4002 `sunknown', `stoken and `snterm'.
4003
4004 2000-10-02 Akim Demaille <akim@epita.fr>
4005
4006 * src/getargs.c (fixed_outfiles): Rename as...
4007 (yaccflag): for consistency and accuracy.
4008 Adjust dependencies.
4009
4010 2000-10-02 Akim Demaille <akim@epita.fr>
4011
4012 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4013 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
4014 difficult and introduced a lot of core dump. It turns out that
4015 Bison used an implementation of `xmalloc' based on `calloc', and
4016 at various places it does depend upon the initialization to 0. I
4017 have not tried to isolate the pertinent places, and all the former
4018 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
4019 someone should address this issue.
4020
4021 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4022 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4029
4030 Various anti-`extern in *.c' changes.
4031
4032 * src/system.h: Include `assert.h'.
4033
4034 2000-10-02 Akim Demaille <akim@epita.fr>
4035
4036 * src/state.h (nstates, final_state, first_state, first_shift)
4037 (first_reduction): Move their exportation from here...
4038 * src/LR0.h: to here.
4039 Adjust dependencies.
4040 * src/getargs.c (statisticsflag): New variable.
4041 Add support for `--statistics'.
4042 Adjust dependencies.
4043
4044 Remove a lot of now useless `extern' statements in most files.

4064 (print_conflicts): this function.
4065 Adjust dependencies.
4066 * src/conflicts.h: New file.
4067 Propagate its inclusion.
4068
4069 2000-10-02 Akim Demaille <akim@epita.fr>

4108 2000-10-02 Akim Demaille <akim@epita.fr>
4109
4110 * src/lalr.h: New file.

4113
4114 2000-10-02 Akim Demaille <akim@epita.fr>
4115
4116 * src/output.c (token_actions): Introduce a temporary array,
4117 YYDEFACT, that makes it possible for this function to use
4118 output_short_table.
4119
4120 2000-10-02 Akim Demaille <akim@epita.fr>
4121
4122 `user_toknums' is output as a `short[]' in `output.c', while it is
4123 defined as a `int[]' in `reader.c'. For consistency with the
4124 other output tables, `user_toknums' is now defined as a table of
4125 shorts.
4126
4127 * src/reader.c (user_toknums): Be a short table instead of an int
4128 table.
4129 Adjust dependencies.
4130
4131 Factor the short table outputs.
4132
4133 * src/output.c (output_short_table): New function.
4134 * src/output.c (output_gram, output_stos, output_rule_data)
4135 (output_base, output_table, output_check): Use it.
4136
4137 2000-10-02 Akim Demaille <akim@epita.fr>
4138
4139 * src/output.c (output): Topological sort of the functions, in
4140 order to get rid of the `static' prototypes.
4141 No longer use `register'.
4142 * src/output.h: New file.
4143 Propagate its inclusion in files explicitly prototyping functions
4144 from output.c.
4145
4146 2000-09-21 Akim Demaille <akim@epita.fr>

4166 inclusion.
4167 Don't define PARAMS.
4168 * src/system.h: Define PARAMS.
4169 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4170 purpose of config.h. system.h must not try to fix wrong
4171 definitions in config.h.
4172
4173 2000-09-20 Akim Demaille <akim@epita.fr>
4174
4175 * src/derives.h: New file.

4389 Change the handling of @s so that they behave exactly like $s.
4390 There is now a pseudo variable @$ (readble and writable), location
4391 of the lhs of the rule (by default ranging from the location of
4392 the first symbol of the rhs, to the location of the last symbol,
4393 or, if the rhs is empty, YYLLOC).

4428 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

5151 (literalchar, lex, parse_percent_token): Made tokenbuffer
5152 always contain the token. This includes growing the token

5154 (parse_percent_token): Replaced if-else statement with percent_table.
5155 (parse_percent_token): Added % declarations as another
5156 way to specify the flags -n, -l, and -r. Also added hooks for
5157 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
5158 major changes to files.c.
5159 (lex) Retain in the incoming stream a character following
5160 an incorrect '/'.
5161 (skip_white_space, lex): Revised most error messages
5162 and changed fatal to warn to avoid aborting.
5163 (percent_table): Added %thong declarations.

5166
5167 * src/files.c (openfiles, open_extra_files, done):
