5 2002-03-04 Akim Demaille <akim@epita.fr>
7 * src/closure.c (ruleset): Be a bitset.
11 2002-03-04 Akim Demaille <akim@epita.fr>
13 * lib/bitset-int.h, lib/bitset.c, lib/bitset.h, lib/bitsetv.c,
14 * lib/bitsetv.h, lib/ebitset.c, lib/ebitset.h, lib/lbitset.c,
15 * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
16 * src/closure.c (fderives): Be an array of bitsets.
18 2002-02-28 Robert Anisko <robert@lrde.epita.fr>

21 notice in each output file.
23 2002-02-28 Akim Demaille <akim@epita.fr>
25 * data/bison.c++: Copy the prologue of bison.simple to fetch
26 useful M4 definitions, such as b4_header_guard.
28 2002-02-25 Akim Demaille <akim@epita.fr>
30 * src/getargs.c (version): Give the name of the authors, and use a
31 translator friendly scheme for the bgr
34 2002-02-25 Akim Demaille <akim@epita.fr>
36 * src/output.c (header_output): Remove, now handled completely via

51 * src/output.c (output_skeleton): Use mkstemp to create a real
53 Move the filling of `skeleton' and its muscle to...
55 (output): Move the definition of the prologue muscle to...
57 * src/system.h (DEFAULT_TMPDIR): New.
59 2002-02-14 Paul Eggert <eggert@twinsun.com>
61 Remove the support for C++ namespace cleanliness; it was
62 causing more problems than it was curing, since it didn't work
63 properly on some nonstandard C++ compilers. This can wait
64 for a proper C++ parser.
66 * NEWS: Document this.
67 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
68 of C++, as it's treated like C now.
69 * src/bison.simple (YYSTD): Remove.
70 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
71 Treat C++ just like Standard C instead of trying to support
72 namespace cleanliness.
74 2002-02-14 Akim Demaille <akim@epita.fr>
76 * tests/regression.at (else): Adjust to Andreas' change.
78 2002-02-14 Akim Demaille <akim@epita.fr>
80 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
82 2002-02-13 Andreas Schwab <schwab@suse.de>
84 * src/output.c (output_rule_data): Don't output NULL, it might

89 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
90 (Copyright notice): Update.
92 2002-02-11 Akim Demaille <akim@epita.fr>
94 * tests/regression.at (%nonassoc and eof): Don't include
97 2002-02-08 Robert Anisko <robert@lrde.epita.fr>

100 initialize the starting location.
102 2002-02-07 Akim Demaille <akim@epita.fr>
104 * tests/input.at: New.
106 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
108 * data/bison.c++: Replace some direct m4 expansions by constants. Be
109 more consistent when naming methods and variables. Put preprocessor
110 directives around tables only needed for debugging.
112 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
114 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
116 (yy::b4_name::parse): Use print_.
118 2002-02-07 Robert Anisko <robert@lrde.epita.fr>

130 * data/bison.c++: Fix m4 quoting in comments.
132 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
134 * data/bison.c++: Adjust the parser code. Fix some muscles that were
137 2002-02-05 Akim Demaille <akim@epita.fr>
139 * data/bison.c++: Adjust to the M4 back end.
140 More is certainly needed.
142 2002-02-05 Akim Demaille <akim@epita.fr>
144 Give a try to M4 as a back end.
146 * lib/readpipe.c: New, from wdiff.
147 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
149 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
150 specific values. Now it is m4 that performs the lookup.
151 * src/parse-skel.y: Remove.
152 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
153 * src/output.c (actions_output, guards_output)
154 (token_definitions_output): No longer keeps track of the output
155 line number, hence remove the second argument.
156 (guards_output): Check against the guard member of a rule, not the
159 (output_skeleton): Don't look for the skeleton location, let m4 do
161 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
163 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
164 (prepare): Given that for the time being changesyntax is not
165 usable in M4, rename the muscles using `-' to `_'.
166 Define `defines_flag', `output_parser_name' and `output_header_name'.
167 * src/output.h (actions_output, guards_output)
168 (token_definitions_output): Adjust prototypes.
169 * src/scan-skel.l: Instead of scanning the skeletons, it now
170 processes the output of m4: `__oline__' and `#output'.
171 * data/bison.simple: Adjust to be used by M4(sugar).
172 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
174 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
175 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
176 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
177 shamelessly stolen from CVS Autoconf.
179 2002-02-05 Akim Demaille <akim@epita.fr>
181 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
182 * configure.in: Check for the declarations of free and malloc.
183 * src/muscle_tab.c: Adjust.
185 2002-02-05 Akim Demaille <akim@epita.fr>
187 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
188 which have no values.
190 2002-02-05 Akim Demaille <akim@epita.fr>
192 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
195 2002-01-29 Paul Eggert <eggert@twinsun.com>
197 * src/bison.simple (YYSIZE_T): Do not define merely because
198 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
199 On some platforms, <alloca.h> does not declare YYSTD (size_t).
201 2002-01-27 Akim Demaille <akim@epita.fr>
203 Fix `%nonassoc and eof'.
205 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
206 which were not properly copied! Replace
207 memcpy (res->errs, src->errs, src->nerrs);
209 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
211 * tests/regression.at (%nonassoc and eof): Adjust to newest
212 Autotest: `.' is not in the PATH.
214 2002-01-27 Akim Demaille <akim@epita.fr>
216 * tests/sets.at (AT_EXTRACT_SETS): New.
220 2002-01-26 Akim Demaille <akim@epita.fr>
222 * tests/actions.at, tests/calc.at, tests/headers.at,
223 * tests/torture.at: Adjust to the newest Autotest which no longer
224 forces `.' in the PATH.
226 2002-01-25 Akim Demaille <akim@epita.fr>
228 * tests/regression.at (%nonassoc and eof): New.
229 Suggested by Robert Anisko.
231 2002-01-24 Akim Demaille <akim@epita.fr>
233 Bison dumps core when trying to complain about broken input files.
234 Reported by Cris van Pelt.
236 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
237 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
239 (Invalid inputs): Strengthen: exercise parse_percent_token.
241 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
243 * src/Makefile.am: Add bison.c++.
244 * src/bison.c++: New skeleton.
246 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
250 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
252 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
254 2002-01-20 Marc Autret <marc@gnu.org>
256 * src/files.c (compute_output_file_names): Fix
258 2002-01-20 Marc Autret <marc@gnu.org>
260 * tests/output.at: New test.
261 * src/files.c (compute_base_names): Don't map extensions when
262 the YACC flag is set, use defaults.
263 Reported by Evgeny Stambulchik.
265 2002-01-20 Marc Autret <marc@gnu.org>
267 * src/system.h: Need to define __attribute__ away for non-GCC
268 compilers as well (i.e. the vendor C compiler).
269 Suggested by Albert Chin-A-Young.
271 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
273 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
274 canonical definition.
275 * src/system.h: Use the canonical definition for PARAMS (avoids
276 a conflict with the macro from lib/hash.h).
278 2002-01-11 Akim Demaille <akim@epita.fr>
280 * configure.in: Use AC_FUNC_STRNLEN.
281 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
283 2002-01-09 Akim Demaille <akim@epita.fr>
285 * src/files.c, src/files.h (output_infix): New.
286 (tab_extension): Remove.
287 (compute_base_names): Compute the former, drop the latter.
288 * src/output.c (prepare): Insert the muscles `output-infix', and
290 * src/parse-skel.y (string, string.1): New.
291 (section.header): Use it.
292 (section.yacc): Remove.
293 (prefix): Remove too.
294 * src/scan-skel.l: Adjust.
295 * src/bison.simple, src/bison.hairy: Adjust.
297 2002-01-09 Akim Demaille <akim@epita.fr>
299 * configure.in (WERROR_CFLAGS): Compute it.
300 * src/Makefile.am (CFLAGS): Pass it.
301 * tests/atlocal.in (CFLAGS): Idem.
302 * src/files.c: Fix a few warnings.
303 (get_extension_index): Remove, unused.
305 2002-01-08 Akim Demaille <akim@epita.fr>
307 * src/getargs.c (AS_FILE_NAME): New.
308 (getargs): Use it to convert DOSish file names.
309 * src/files.c (base_name): Rename as full_base_name to avoid
310 clashes with `base_name ()'.
311 (filename_split): New.
312 (compute_base_names): N-th rewrite, using filename_split.
314 2002-01-08 Akim Demaille <akim@epita.fr>
316 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
317 New, stolen from the Fileutils 4.1.
318 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
319 * configure.in: Check for the presence of memrchr, and of its
322 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
324 * lib/hash.h (__P): Added definition for this macro.
325 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
326 BUILT_SOURCES, to ensure they are generated first.
327 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
328 %error-verbose to allow bootstrapping with bison 1.30x.
330 2002-01-06 Akim Demaille <akim@epita.fr>
332 * src/reader.c (parse_braces): Don't fetch the next char, the
333 convention is to fetch on entry.
334 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
335 'switch' without a following semicolon.
336 * tests/regression.at (braces parsing): New.
338 2002-01-06 Akim Demaille <akim@epita.fr>
340 Bison is dead wrong in its RR conflict reports.
342 * tests/torture.at (GNU Cim Grammar): New.
343 * src/conflicts.c (count_rr_conflicts): Fix.
345 2002-01-06 Akim Demaille <akim@epita.fr>
347 Creating package.m4 from configure.ac causes too many problems.
349 * tests/Makefile.am (package.m4): Create it by hand,
350 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
352 2002-01-06 Akim Demaille <akim@epita.fr>
354 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
357 2002-01-04 Paul Eggert <eggert@twinsun.com>
359 * doc/bison.texinfo (Debugging):
360 Remove YYSTDERR; it's no longer defined or used.
361 Also, s/cstdio.h/cstdio/.
363 2002-01-03 Akim Demaille <akim@epita.fr>
365 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
367 2002-01-03 Akim Demaille <akim@epita.fr>
369 * src/parse-skel.y (process_skeleton): Don't bind the parser's
370 tracing code to --trace, wait for a better --trace option, with
373 2002-01-03 Akim Demaille <akim@epita.fr>
375 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
376 The ISO C++ standard is extremely clear about it: stderr is
377 considered a macro, not a regular symbol (see table 94 `Header
378 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
379 Therefore std:: does not apply to it. It still does with fprintf.
380 Also, s/cstdio.h/cstdio/.
382 2002-01-03 Akim Demaille <akim@epita.fr>
384 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
385 for non system headers.
387 2002-01-02 Akim Demaille <akim@epita.fr>
389 Equip the skeleton chain with location tracking, runtime trace,
390 pure parser and scanner.
392 * src/parse-skel.y: Request a pure parser, locations, and prefix
394 (%union): Having several members with the same type does not help
395 type mismatches, simplify.
396 (YYPRINT, yyprint): New.
397 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
400 * src/scan-skel.l: Adjust to these changes.
401 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
402 (LOCATION_PRINT, skel_control_t): New.
404 2001-12-30 Akim Demaille <akim@epita.fr>
406 * src/parse-skel.y: Get rid of the shift/reduce conflict:
407 replace `gb' with BLANKS.
408 * src/scan-skel.l: Adjust.
410 2001-12-30 Akim Demaille <akim@epita.fr>
412 * src/system.h: We don't need nor want bcopy.
413 Throw away MS-DOS crap: we don't need getpid.
414 * configure.in: We don't need strndup. It was even causing
415 problems: because Flex includes the headers *before* us,
416 _GNU_SOURCE is not defined by config.h, and therefore strndup was
418 * lib/xstrndup.c: New.
419 * src/scan-skel.l: Use it.
420 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
421 * src/parse-skel.y: Use %directives instead of #defines.
423 2001-12-30 Akim Demaille <akim@epita.fr>
425 * src/skeleton.h: New.
426 * src/output.c (output_parser, output_master_parser): Remove, dead
428 * src/output.h (get_lines_number, actions_output, guards_output)
429 (token_definitions_output): Prototype them.
430 * src/parse-skel.y: Add the license notice.
431 Include output.h and skeleton.h.
432 (process_skeleton): Returns void, and takes a single parameter.
433 * src/scan-skel.l: Add the license notice.
435 Don't use %option yylineno: it seems that then Flex imagines
436 REJECT has been used, and therefore it won't reallocate its
437 buffers (which makes no other sense to me than a bug). It results
438 in warnings for `unused: yy_flex_realloc'.
440 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
442 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
443 (MUSCLE_INSERT_PREFIX): ...to there.
444 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
445 (MUSCLE_INSERT_PREFIX): Move from here...
447 * src/bison.hairy: Add a section directive. Put braces around muscle
448 names. This parser skeleton is still broken, but Bison should not
449 choke on a bad muscle 'syntax'.
450 * src/bison.simple: Add a section directive. Put braces around muscle
453 * src/files.h (strsuffix, stringappend): Add declarations.
454 (tab_extension): Add declaration.
455 (short_base_name): Add declaration.
457 * src/files.c (strsuffix, stringappend): No longer static. These
458 functions are used in the skeleton parser.
459 (tab_extension): New.
460 (compute_base_names): Use the computations done in this function
461 to guess if the generated parsers should have '.tab' in their
463 (short_base_name): No longer static.
465 * src/output.c (output_skeleton): New.
466 (output): Disable call to output_master_parser, and give a try to
467 a new skeleton handling system.
468 (guards_output, actions_output): No longer static.
469 (token_definitions_output, get_lines_number): No longer static.
471 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
473 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
476 * src/parse-skel.y: New file.
477 * src/scan-skel.l: New file.
479 2001-12-29 Akim Demaille <akim@epita.fr>
481 %name-prefix is broken.
483 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
484 Adjust all dependencies.
485 * tests/headers.at (export YYLTYPE): Strengthen this test: use
488 Renaming yylval but not yylloc is not consistent. Now we do.
490 * src/bison.simple: Prefix yylloc if used.
491 * doc/bison.texinfo (Decl Summary): Document that.
493 2001-12-29 Akim Demaille <akim@epita.fr>
495 * doc/bison.texinfo: Promote `%long-directive' over
497 Remove all references to fixed-output-files, yacc is enough.
499 2001-12-29 Akim Demaille <akim@epita.fr>
501 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
502 user prologue. These are defaults.
503 * tests/actions.at (Mid-rule actions): Make sure the user can
504 define YYDEBUG and YYERROR_VERBOSE.
506 2001-12-29 Akim Demaille <akim@epita.fr>
508 * src/output.c (header_output): Don't forget to export YYLTYPE and
510 * tests/headers.at (export YYLTYPE): New, make sure it does.
511 * tests/regression.at (%union and --defines, Invalid CPP headers):
513 * tests/headers.at: here.
515 2001-12-29 Akim Demaille <akim@epita.fr>
517 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
519 2001-12-29 Akim Demaille <akim@epita.fr>
521 * tests/actions.at (Mid-rule actions): Output on a single line
524 2001-12-29 Akim Demaille <akim@epita.fr>
526 * doc/bison.texinfo: Formatting changes.
528 2001-12-29 Akim Demaille <akim@epita.fr>
530 Don't store the token defs in a muscle, just be ready to output it
531 on command. Now possible via `symbols'. Fixes a memory leak.
533 * src/output.c (token_definitions_output): New.
534 (output_parser, header_output): Use it.
535 * src/reader.c (symbols_save): Remove.
537 2001-12-29 Akim Demaille <akim@epita.fr>
539 * src/bison.simple: Do not provide a default for YYSTYPE and
540 YYLTYPE before the user's prologue. Otherwise it's hardly... a
543 2001-12-29 Akim Demaille <akim@epita.fr>
545 Mid-rule actions are simply... ignored!
547 * src/reader.c (readgram): Be sure to attach mid-rule actions to
548 the empty-rule associated to the dummy symbol, not to the host
550 * tests/actions.at (Mid-rule actions): New.
552 2001-12-29 Akim Demaille <akim@epita.fr>
556 * src/reader.c (reader): Free grammar.
558 2001-12-29 Akim Demaille <akim@epita.fr>
562 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
563 since it allocates it for each state, although only one is needed.
564 (allocate_storage): Do it here.
566 2001-12-29 Akim Demaille <akim@epita.fr>
568 * src/options.h, src/options.c (create_long_option_table): Rename
570 (long_option_table_new): this, with a clearer prototype.
571 (percent_table): Remove, unused,
572 * src/getargs.c (getargs): Adjust.
574 2001-12-29 Akim Demaille <akim@epita.fr>
576 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
577 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
580 2001-12-29 Akim Demaille <akim@epita.fr>
582 * src/lalr.c (build_relations): Rename `states' as `states1'.
583 Sorry, I don't understand exactly what it is, no better name...
585 2001-12-29 Akim Demaille <akim@epita.fr>
587 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
588 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
589 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
592 2001-12-29 Akim Demaille <akim@epita.fr>
594 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
597 2001-12-29 Akim Demaille <akim@epita.fr>
599 * src/reader.c, src/reader.h (user_toknums): Remove.
600 Adjust all users to use symbols[i]->user_token_number.
602 2001-12-29 Akim Demaille <akim@epita.fr>
604 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
605 Adjust all users to use symbols[i]->prec or ->assoc.
607 2001-12-29 Akim Demaille <akim@epita.fr>
609 * src/reader.c, src/reader.h (tags): Remove.
610 Adjust all users to use symbols[i]->tag.
612 2001-12-29 Akim Demaille <akim@epita.fr>
614 * src/gram.h, src/gram.c (symbols): New, similar to state_table
616 * src/reader.c (packsymbols): Fill this table.
618 * src/conflicts.c (resolve_sr_conflict): Adjust.
619 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
621 Use symbols[i]->tag instead of tags[i].
623 2001-12-29 Akim Demaille <akim@epita.fr>
625 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
626 In addition, put a comment in there, to replace...
627 * tests/regression.at (%union and C comments): Remove.
629 2001-12-29 Akim Demaille <akim@epita.fr>
631 * tests/regression.at (Web2c Actions): Blindly move the actual
632 output as expected output. The contents *seem* right to me, but I
633 can't pretend reading perfectly parser tables... Nonetheless, all
634 the other tests pass correctly, the table look OK, even though the
635 presence of `$axiom' is to be noted: AFAICS it is useless (but
638 2001-12-29 Akim Demaille <akim@epita.fr>
640 * src/reader.c (readgram): Don't add the rule 0 if there were no
641 rules read. In other words, add it _after_ having performed
642 grammar sanity checks.
643 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
645 2001-12-29 Akim Demaille <akim@epita.fr>
647 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
648 visible, and some states have now a different number.
650 2001-12-29 Akim Demaille <akim@epita.fr>
652 * src/reader.c (readgram): Bind the initial rule's lineno to that
654 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
655 (Solved SR Conflicts): Adjust rule 0's line number.
657 2001-12-29 Akim Demaille <akim@epita.fr>
659 Fix the `GAWK Grammar' failure.
661 * src/LR0.c (final_state): Initialize to -1 so that we do compute
662 the reductions of the first state which was mistakenly confused
663 with the final state because precisely final_state was initialized
665 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
666 now noticed by Bison.
667 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
668 have a reduction on $default.
670 2001-12-29 Akim Demaille <akim@epita.fr>
672 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
674 * src/closure.c (print_closure): Likewise.
675 * src/derives.c (print_derives): Likewise.
676 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
679 2001-12-29 Akim Demaille <akim@epita.fr>
681 * src/lalr.c (lookaheads_print): New.
682 (lalr): Call it when --trace-flag.
683 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
686 2001-12-29 Akim Demaille <akim@epita.fr>
688 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
689 when walking through ritem, even via rule->rhs.
690 * src/reduce.c (dump_grammar, useful_production, reduce_output)
691 (useful_production, useless_nonterminals): Likewise.
692 (reduce_grammar_tables): Likewise, plus update nritems.
693 * src/nullable.c (set_nullable): Likewise.
694 * src/lalr.c (build_relations): Likewise.
695 * tests/sets.at (Nullable): Adjust.
696 Fortunately, now, the $axiom is no longer nullable.
698 2001-12-29 Akim Demaille <akim@epita.fr>
700 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
702 * src/gram.c (ritem_longest_rhs): Likewise.
703 * src/reduce.c (nonterminals_reduce): Likewise.
704 * src/print_graph.c (print_graph): Likewise.
705 * src/output.c (output_rule_data): Likewise.
706 * src/nullable.c (set_nullable): Likewise.
708 2001-12-29 Akim Demaille <akim@epita.fr>
710 * src/output.c: Comment changes.
712 2001-12-27 Paul Eggert <eggert@twinsun.com>
714 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
715 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
716 Sparc, as they were causing more porting problems than the
717 (minor) performance improvement was worth.
719 Also, catch up with 1.31's YYSTD.
721 2001-12-27 Akim Demaille <akim@epita.fr>
723 * src/output.c (output_gram): Rely on nritems, not the
724 0-sentinel. See below.
725 Use -1 as separator, not 0.
726 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
727 Rely on -1 as separator in yyrhs, instead of 0.
728 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
729 twice `Now at end of input', therefore there are two lines less to
732 2001-12-27 Akim Demaille <akim@epita.fr>
734 * tests/regression.at (Unresolved SR Conflicts):
735 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
738 2001-12-27 Akim Demaille <akim@epita.fr>
740 * src/LR0.c (new_state): Recognize the final state by the fact it
741 is reached by eoftoken.
742 (insert_start_shifting_state, insert_eof_shifting_state)
743 (insert_accepting_state, augment_automaton): Remove, since now
744 these states are automatically computed from the initial state.
745 (generate_states): Adjust.
746 * src/print.c: When reporting a rule number to the user, substract
747 1, so that the axiom rule is rule 0, and the first user rule is 1.
748 * src/reduce.c: Likewise.
749 * src/print_graph.c (print_core): For the time being, just as for
750 the report, depend upon --trace-flags to dump the full set of
752 * src/reader.c (readgram): Once the grammar read, insert the rule
753 0: `$axiom: START-SYMBOL $'.
754 * tests/set.at: Adjust: rule 0 is now displayed, and since the
755 number of the states has changed (the final state is no longer
756 necessarily the last), catch up.
758 2001-12-27 Akim Demaille <akim@epita.fr>
760 Try to make the use of the eoftoken valid. Given that its value
761 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
762 is used instead of > 0 where appropriate, (ii), depend upon nritems
763 instead of the 0-sentinel.
765 * src/gram.h, src/gram.c (nritems): New.
766 Expected to be duplication of nitems, but for the time being...
767 * src/reader.c (packgram): Assert nritems and nitems are equal.
768 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
769 * src/closure.c (print_closure, print_fderives): Likewise.
770 * src/gram.c (ritem_print): Likewise.
771 * src/print.c (print_core, print_grammar): Likewise.
772 * src/print_graph.c: Likewise.
774 2001-12-27 Akim Demaille <akim@epita.fr>
776 * src/main.c (main): If there are complains after grammar
777 reductions, then output the report anyway if requested, then die.
778 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
779 * src/reader.c (eoftoken): New.
780 (parse_token_decl): If the token being defined has value `0', it
782 (packsymbols): No longer hack `tags' to insert `$' by hand.
783 Be sure to preserve the value of the eoftoken.
784 (reader): Make sure eoftoken is defined.
785 Initialize nsyms to 0: now eoftoken is created just like the others.
786 * src/print.c (print_grammar): Don't special case the eof token.
787 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
788 lie anyway, albeit pleasant.
789 * tests/calc.at: Exercise error messages with eoftoken.
790 Change the grammar so that empty input is invalid.
792 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
794 2001-12-27 Akim Demaille <akim@epita.fr>
796 * configure.in: Check the protos of strchr ans strspn.
797 Replace strchr if needed.
798 * src/system.h: Provide the protos of strchr, strspn and memchr if
801 * src/reader.c (symbols_save): Use strchr.
803 2001-12-27 Akim Demaille <akim@epita.fr>
805 * src/print.c, src/print_graph.c (escape): New.
806 Use it to quote the TAGS outputs.
807 * src/print_graph.c (print_state): Now errors are in red, and
809 Prefer high to wide: output the state number on a line of its own.
811 2001-12-27 Akim Demaille <akim@epita.fr>
813 * src/state.h, src/state.c (reductions_new): New.
814 * src/LR0.c (set_state_table): Let all the states have a
815 `reductions', even if reduced to 0.
816 (save_reductions): Adjust.

818 * src/print.c (print_reductions, print_actions): Adjust.

825 even if reduced to 0.
826 * src/print.c (print_errs, print_reductions): Adjust.
827 * src/output.c (output_actions, action_row): Adjust.
828 * src/conflicts.c (resolve_sr_conflict): Adjust.
830 2001-12-27 Akim Demaille <akim@epita.fr>
832 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
834 2001-12-27 Akim Demaille <akim@epita.fr>
836 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
838 (lookaheadset, shiftset): New, used as additional storage by
840 (print_results): Adjust.
841 (print_shifts, print_gotos, print_errs): New, extracted from...
842 (print_actions): here.
843 * src/print_graph.c (print_actions): Remove dead code.
845 2001-12-27 Akim Demaille <akim@epita.fr>
847 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
850 2001-12-27 Akim Demaille <akim@epita.fr>
852 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

862 * src/reader.c (packgram): Catch nitems overflows.
864 2001-12-27 Akim Demaille <akim@epita.fr>
866 * src/files.c, src/files.h (guard_obstack): Remove.
867 * src/output.c (output): Adjust.
868 * src/reader.c (parse_braces): New, factoring...
869 (copy_action, copy_guard): these two which are renamed as...
870 (parse_action, parse_guard): these.
871 As a voluntary consequence, using braces around guards is now
874 2001-12-27 Akim Demaille <akim@epita.fr>
876 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
877 * src/reader.c (symbol_list): `guard' and `guard_line' are new
879 (symbol_list_new): Adjust.
880 (copy_action): action_line is the first line, not the last.
881 (copy_guard): Just as for actions, store the `action' only, not
882 the switch/case/break flesh.
883 Don't parse the user action that might follow the guard, let...
884 (readgram): do it, i.e., now, there can be an action after a
886 In other words the guard is just explicitly optional.
888 * src/output.c (guards_output): New.
889 (output_parser): Call it when needed.
890 (output): Also free the guard and attrs obstacks.
891 * src/files.c, src/files.h (obstack_save): Remove.
892 (output_files): Remove.
893 As a result, if one needs the former `.act' file, using an
894 appropriate skeleton which requires actions and guards is now
896 * src/main.c (main): Adjust.
897 * tests/semantic.at: New.
898 * tests/regression.at: Use `input.y' as input file name.
899 Avoid 8+3 problems by requiring input.c when the test needs the

904 * src/reader.c (symbol_list_new): Be sure to initialize all the

909 All the hacks using a final pseudo state are now useless.
911 * src/LR0.c (set_state_table): state_table holds exactly nstates.
912 * src/lalr.c (nLA): New.
913 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
914 instead of lookaheadsp from the pseudo state (nstate + 1).
916 2001-12-27 Akim Demaille <akim@epita.fr>
918 * src/output.c (action_row, token_actions): Use a state_t instead
919 of a integer, and nlookaheads instead of the following state's

925 (resolve_sr_conflict, set_conflicts, solve_conflicts)
926 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
927 (conflicts_print, print_reductions): Use a state_t instead of an
928 integer when referring to a state.
929 As much as possible, depend upon nlookaheads, instead of the
930 `lookaheadsp' member of the following state (since lookaheads of
931 successive states are successive, the difference between state n + 1
932 and n served as the number of lookaheads for state n).
933 * src/lalr.c (add_lookback_edge): Likewise.
934 * src/print.c (print_core, print_actions, print_state)
935 (print_results): Likewise.
936 * src/print_graph.c (print_core, print_actions, print_state)

942 * src/bison.hairy: Formatting/comment changes.
944 Remove `register' indications.
945 Add plenty of `static'.
947 2001-12-27 Akim Demaille <akim@epita.fr>
949 * src/output.c (prepare): Drop the muscle `ntbase' which
951 * src/bison.simple: Formatting/comment changes.
952 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
953 is an undocumented synonym.
955 2001-12-22 Akim Demaille <akim@epita.fr>
957 * src/output.c (output_table_data): Change the prototype to use
958 `int' for array ranges: some invocations do pass an int, not a
960 Reported by Wayne Green.
962 2001-12-22 Akim Demaille <akim@epita.fr>
964 Some actions of web2c.y are improperly triggered.
965 Reported by Mike Castle.

978 * tests/regression.at (Web2c): New.
980 2001-12-18 Akim Demaille <akim@epita.fr>
982 Some host fail on `assert (!"foo")', which expands to
983 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
984 Reported by Nelson Beebee.
986 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
987 `#define it_succeeded 0' and `assert (it_succeeded)'.
989 2001-12-17 Marc Autret <autret_m@epita.fr>
991 * src/bison.simple: Don't hard code the skeleton line and filename.
992 * src/output.c (output_parser): Rename 'line' as 'output_line'.
993 New line counter 'skeleton_line' (skeleton-line muscle).
995 2001-12-17 Paul Eggert <eggert@twinsun.com>
997 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
998 YYDEBUG must be defined to a nonzero value.
1000 * src/bison.simple (yytname): Do not assume that the user defines
1001 YYDEBUG to a properly parenthesized expression.
1003 2001-12-17 Akim Demaille <akim@epita.fr>
1005 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

1021 * src/conflicts.c (print_reductions): Formatting changes.
1023 2001-12-17 Akim Demaille <akim@epita.fr>
1025 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1026 (flush_reduce): New.
1027 (resolve_sr_conflict): Adjust.
1029 2001-12-17 Akim Demaille <akim@epita.fr>
1031 * src/output.c (output_obstack): Be static and rename as...
1032 (format_obstack): this, to avoid any confusion with files.c's
1034 * src/reader.h (muscle_obstack): Move to...
1035 * src/output.h: here, since it's defined in output.c.
1037 2001-12-17 Akim Demaille <akim@epita.fr>
1039 * src/output.c (action_row, save_column, default_goto)
1040 (sort_actions, matching_state, pack_vector): Better variable
1043 2001-12-17 Akim Demaille <akim@epita.fr>
1045 * src/output.c: Various formatting changes.
1047 2001-12-17 Akim Demaille <akim@epita.fr>

1055 2001-12-16 Marc Autret <autret_m@epita.fr>
1057 * src/output.c (actions_output): Fix. When we use %no-lines,
1058 there is one less line per action.
1060 2001-12-16 Marc Autret <autret_m@epita.fr>
1062 * src/bison.simple: Remove a useless #line directive.
1063 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1064 * src/output.c (get_lines_number): New.
1065 (output_parser): Adjust, now takes care about the lines of a
1068 (actions_output): Computes the number of lines taken by actions.
1069 (output_master_parser): Insert new skeleton which is the name of

1078 * src/output.c (output_gram): Keep track of the hairy one.
1080 2001-12-15 Akim Demaille <akim@epita.fr>
1082 Make `make distcheck' work.
1084 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1085 system.h which uses libgettext.h.
1087 2001-12-15 Akim Demaille <akim@epita.fr>
1089 * src/nullable.c (set_nullable): Useless rules must be skipped,
1090 otherwise, since we range over their symbols, we might look at a
1091 nonterminal which no longer ``exists'', i.e., it is not counted in
1092 `nvars', hence we overflow our arrays.
1094 2001-12-15 Akim Demaille <akim@epita.fr>
1096 The header can also be produced directly, without any obstack!
1099 * src/files.c, src/files.h (defines_obstack): Remove.
1100 (compute_header_macro): Global.
1101 (defines_obstack_save): Remove.
1102 * src/reader.c (parse_union_decl): No longer output to
1103 defines_obstack: its content can be found in the `stype' muscle
1105 (output_token_translations): Merge into...
1106 (symbols_output): this.
1108 (symbols_save): this.
1110 * src/output.c (header_output): New.
1113 2001-12-15 Akim Demaille <akim@epita.fr>
1115 * src/reader.c (parse_union_decl): Instead of handling two obstack
1116 simultaneously, use one to define the `stype' muscle, and use the
1117 value of the latter to fill defines_obstack.
1118 (copy_comment): Remove.
1119 (copy_comment2): Work for a single obstack.
1121 (copy_comment): this.

1125 * src/lex.c, src/lex.h (xgetc): No longer static.
1126 * src/reader.c (parse_union_decl): Revamp.
1128 2001-12-15 Akim Demaille <akim@epita.fr>
1130 Still making progress in separating Bison into (i) input, (ii)
1131 process, (iii) output: now we can directly output the parser file
1132 without using table_obstack at all.
1134 * src/files.c, src/files.h (table_obstack): Bye bye.
1135 (parser_file_name): New.
1136 * src/files.c (compute_output_file_names): Compute it.
1137 * src/output.c (actions_output, output_parser)
1138 (output_master_parser): To a file instead of an obstack.
1140 2001-12-15 Akim Demaille <akim@epita.fr>
1142 Attach actions to rules, instead of pre-outputting them to
1145 * src/gram.h (rule_t): action and action_line are new members.
1146 * src/reader.c (symbol_list): Likewise.
1147 (copy_action): Save the actions within the rule.
1148 (packgram): Save them in rule_table.
1149 * src/output.c (actions_output): New.
1150 (output_parser): Use it on `%%actions'.
1151 (output_rule_data): Don't free rule_table.
1153 (prepare): Don't save the `action' muscle.
1154 * src/bison.simple: s/%%action/%%actions/.
1156 2001-12-15 Akim Demaille <akim@epita.fr>
1158 * src/reader.c (copy_action): When --yacc, don't append a `;'
1159 to the user action: let it fail if lacking.
1160 Suggested by Arnold Robbins and Tom Tromey.
1162 2001-12-14 Akim Demaille <akim@epita.fr>
1164 * src/lex.c (literalchar): Simply return the char you decoded, non
1165 longer mess around with obstacks and int pointers.
1168 2001-12-14 Akim Demaille <akim@epita.fr>
1170 * src/lex.c (literalchar): Don't escape the special characters,
1171 just decode them, and keep them as char (before, eol was output as
1172 the 2 char string `\n' etc.).
1173 * src/output.c (output_rule_data): Use quotearg to output the
1176 2001-12-13 Paul Eggert <eggert@twinsun.com>
1178 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1179 Do not infringe on the global user namespace when using C++.
1180 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1181 All uses of `fprintf' and `stderr' changed.
1183 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1185 2001-12-13 Akim Demaille <akim@epita.fr>
1187 The computation of nullable is broken: it doesn't handle empty
1190 * tests/torture.at (GNU AWK Grammar): New.
1191 * tests/sets.at (Nullable): New.
1192 * src/nullable.c (set_nullable): Instead of blindly looping over
1193 `ritems', loop over the rules, and then over their rhs's.
1195 Work around Autotest bugs.
1197 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1198 frame, because Autotest understand lines starting with a `+' as
1199 traces from the shell. Then, they are not processed properly.
1200 Admittedly an Autotest bug, but we don't have time to wait for
1201 Autotest to catch up.
1202 * tests/regression.at (Broken Closure): Adjust to the new table
1205 * tests/sets.at: here.
1207 2001-12-13 Akim Demaille <akim@epita.fr>
1209 * src/closure.c (closure): Use nrules instead of playing tricks
1212 2001-12-13 Akim Demaille <akim@epita.fr>
1214 * src/print.c (print_actions): Output the handling of `$' as the
1215 traces do: shifting the token EOF. Before EOF was treated as a
1217 * tests/regression.at: Adjust some tests.
1218 * src/print_graph.c (print_core): Complete the set of items via
1219 closure. The next-to-final and final states are still unsatisfying,
1220 but that's to be addressed elsewhere.
1221 No longer output the rule numbers, but do output the state number.
1222 A single loop for the shifts + gotos is enough, but picked a
1223 distinct color for each.
1224 (print_graph): Initialize and finalize closure.
1226 2001-12-13 Akim Demaille <akim@epita.fr>
1228 * src/reader.c (readgram): Remove dead code, an strip useless
1230 (get_type): Remove, unused.
1232 2001-12-12 Akim Demaille <akim@epita.fr>
1234 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1235 on that of lib/error.c.
1237 2001-12-12 Akim Demaille <akim@epita.fr>
1239 Some hosts don't like `/' in includes.
1241 * src/system.h: Include libgettext.h without qualifying the path.
1242 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1245 2001-12-11 Marc Autret <autret_m@epita.fr>
1247 * src/output.c (output_parser): Remove useless muscle.
1249 2001-12-11 Marc Autret <autret_m@epita.fr>
1251 * src/bison.simple: Remove #line just before %%epilogue. It
1252 is now handled in ...
1253 * src/reader.c (read_additionnal_code): Add the output of a
1254 #line for the epilogue.
1256 2001-12-10 Marc Autret <autret_m@epita.fr>
1258 * src/reader.c (copy_definition): Re-use CPP-outed code which
1259 replace precedent remove.
1260 * src/bison.simple: Remove #line before %%prologue because
1261 %%input-line is wrong at this time.
1263 2001-12-10 Marc Autret <autret_m@epita.fr>
1265 * src/reader.c (symbols_output): Clean up.
1266 * src/output.c (output_gram, output): Clean up.
1268 2001-12-10 Akim Demaille <akim@epita.fr>
1270 * src/lalr.c (initialize_lookaheads): New. Extracted from...
1271 * src/LR0.c (set_state_table): here.
1272 * src/lalr.c (lalr): Call it.
1274 2001-12-10 Akim Demaille <akim@epita.fr>
1276 * src/state.h (shifts): Remove the `number' member: shifts are
1277 attached to state, hence no longer need to be labelled with a
1280 2001-12-10 Akim Demaille <akim@epita.fr>
1282 Now that states have a complete set of members, the linked list of
1283 shifts is useless: just fill directly the state's shifts member.
1285 * src/state.h (shifts): Remove the `next' member.
1286 * src/LR0.c (first_state, last_state): Remove.
1288 (augment_automaton): Don't look for the shifts that must be added
1289 a shift on EOF: it is those of the state we looked for! But now,
1290 since shifts are attached, it is no longer needed to looking
1291 merely by its id: its number.
1293 2001-12-10 Akim Demaille <akim@epita.fr>
1295 * src/LR0.c (augment_automaton): Better variable locality.
1296 Remove an impossible branch: if there is a state corresponding to
1297 the start symbol being shifted, then there is shift for the start
1298 symbol from the initial state.
1300 2001-12-10 Akim Demaille <akim@epita.fr>
1302 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1303 only when appropriate: when insert_start_shifting_state' is not
1305 * tests/regression.at (Rule Line Numbers): Adjust.
1307 2001-12-10 Akim Demaille <akim@epita.fr>
1309 * src/LR0.c (augment_automaton): Now that all states have shifts,
1310 merge the two cases addition shifts to the initial state.
1312 2001-12-10 Akim Demaille <akim@epita.fr>
1314 * src/lalr.c (set_state_table): Move to...
1316 * src/lalr.c (lalr): Don't call it...
1317 * src/LR0.c (generate_states): do it.
1318 * src/LR0.h (first_state): Remove, only the table is used.
1320 2001-12-10 Akim Demaille <akim@epita.fr>
1322 * src/LR0.h (first_shift, first_reduction): Remove.
1323 * src/lalr.c: Don't use first_shift: find shifts through the
1326 2001-12-10 Akim Demaille <akim@epita.fr>
1328 * src/LR0.c: Attach shifts to states as soon as they are
1330 * src/lalr.c (set_state_table): Instead of assigning shifts to
1331 state, just assert that the mapping was properly done.
1333 2001-12-10 Akim Demaille <akim@epita.fr>
1335 * src/LR0.c (insert_start_shift): Rename as...
1336 (insert_start_shifting_state): this.
1337 (insert_eof_shifting_state, insert_accepting_state): New.
1338 (augment_automaton): Adjust.
1339 Better locality of the variables.
1340 When looking if the start_symbol is shifted from the initial
1341 state, using `while (... symbol != start_symbol ...)' sounds
1342 better than `while (... symbol < start_symbol ...)': If fail
1343 to see how the order between symbols could be relevant!
1345 2001-12-10 Akim Demaille <akim@epita.fr>
1347 * src/getargs.h: Don't declare `spec_name_prefix' and
1348 `spec_file_prefix', declared by src/files.h.
1349 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1350 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1351 * src/output.c (prepare): Adjust.
1352 * src/reader.c (symbols_output): Likewise.
1353 * src/vmsgetargs.c: Vaguely adjust, but who cares?
1355 2001-12-10 Akim Demaille <akim@epita.fr>
1357 * src/muscle_tab.c (muscle_init): NULL is a better default than
1360 2001-12-10 Akim Demaille <akim@epita.fr>
1362 * src/reader.c (reader): Calling symbols_output once is enough.
1364 2001-12-10 Akim Demaille <akim@epita.fr>
1366 Now that states have a complete set of members, the linked list of
1367 reductions is useless: just fill directly the state's reductions
1370 * src/state.h (struct reductions): Remove member `number' and
1372 * src/LR0.c (first_reduction, last_reduction): Remove.
1373 (save_reductions): Don't link the new reductions, store them in
1375 * src/lalr.c (set_state_table): No need to attach reductions to
1376 states, it's already done.
1377 * src/output.c (output_actions): No longer free the shifts, then
1378 the reductions, then the states: free all the states and their
1381 2001-12-10 Akim Demaille <akim@epita.fr>
1383 * src/options.c (OPTN, DRTV, BOTH): New.
1384 (option_table): Use them.
1386 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1387 the job of system.h.
1388 * src/options.c: Don't include stdio.h and xalloc.h for the same
1391 2001-12-10 Akim Demaille <akim@epita.fr>
1393 * src/output.c (output, prepare): Make sure the values of the
1394 muscles `action' and `prologue' are 0-terminated.
1396 2001-12-10 Akim Demaille <akim@epita.fr>
1398 Clean up GCC warnings.
1400 * src/reader.c (copy_action): `buf' is not used.
1401 (parse_skel_decl): Be static.
1402 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1403 * src/options.h (create_long_option_table): Have a real prototype.
1404 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1405 (hash_delete_at): Return const void *.
1406 Adjust casts to preserve the const.
1408 2001-12-10 Akim Demaille <akim@epita.fr>
1410 * configure.in: Require 2.52g.
1411 M4 is not needed, but AUTOM4TE is.
1413 * tests/Makefile.am: Adjust.
1415 2001-12-10 Akim Demaille <akim@epita.fr>
1417 One structure for states is enough, even though theoretically
1418 there are LR(0) states and LALR(1) states.
1420 * src/lalr.h (state_t): Remove.
1421 (state_table): Be state_t **, not state_t *.
1422 * src/state.h (core, CORE_ALLOC): Rename as...
1423 (state_t, STATE_ALLOC): this.
1424 Add the LALR(1) members: shifts, reductions, errs.
1425 * src/LR0.c (state_table): Rename as...
1426 (state_hash): this, to avoid name clashes with the global
1428 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1429 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1431 2001-12-10 Akim Demaille <akim@epita.fr>
1433 Bison dumps core on bash.y.
1434 Reported by Pascal Bart.
1436 * src/warshall.c (bitmatrix_print): New.
1438 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1439 j must be the outer loop.
1440 * tests/regression.at (Broken Closure): New.
1442 2001-12-05 Akim Demaille <akim@epita.fr>
1444 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1446 Reported by Peter Hámorský.
1448 2001-12-05 Akim Demaille <akim@epita.fr>
1450 * src/conflicts.c (err_table): Remove.
1451 (resolve_sr_conflict): Adjust.
1452 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1454 (state_t.reductions, state_t.shifts): this.
1456 2001-12-05 Akim Demaille <akim@epita.fr>
1458 * src/reduce.c (reduce_grammar_tables): No longer disable the
1459 removal of useless rules via CPP but via `if (0)', so that the
1460 compiler still check the code is valid.
1461 For instance, it should have noticed `rline' no longer exists: use
1462 the `line' member of rule_t.
1463 * src/gram.c (dummy, rline): Remove, unused.
1465 2001-12-05 Akim Demaille <akim@epita.fr>
1467 * src/output.c (pack_vector): Use assert, not berror.
1468 * src/main.c (berror): Remove, unused.
1470 2001-12-05 Akim Demaille <akim@epita.fr>
1472 New experimental feature: if --verbose --trace output all the
1473 items of a state, not only its kernel.
1475 * src/print.c (print_core): If `trace_flag', then invoke closure
1476 before outputting the items of the state (print_core is no longer
1477 a correct name them).
1478 (print_results): Invoke new_closure/free_closure if needed.
1480 2001-12-05 Akim Demaille <akim@epita.fr>
1482 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1483 * src/closure.c, src/closure.h (itemsetsize): Rename as...
1484 (nitemset): for consistency with the rest of the project.
1486 2001-12-05 Akim Demaille <akim@epita.fr>
1488 * src/closure.c (print_closure): Improve.
1489 (closure): Use it for printing input and output.
1491 2001-12-05 Akim Demaille <akim@epita.fr>
1493 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1494 indexed by nonterminals.
1496 2001-12-05 Akim Demaille <akim@epita.fr>
1498 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1500 * src/warshall.h: Remove accidental duplication of the content.
1502 2001-12-05 Akim Demaille <akim@epita.fr>

1514 2001-12-05 Akim Demaille <akim@epita.fr>
1516 * src/output.c (action_row): De-obfuscate
1517 using the good o' techniques: arrays not pointers, variable
1518 locality, BITISSET, RESETBIT etc.
1520 2001-12-05 Akim Demaille <akim@epita.fr>
1522 Pessimize the code to simplify it: from now on, all the states
1523 have a valid SHIFTS, which NSHIFTS is possibly 0.
1525 * src/LR0.c (shifts_new): Be global and move to..
1526 * src/state.c, src/state.h: here.
1527 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1528 * src/print_graph: Adjust.
1530 2001-12-05 Akim Demaille <akim@epita.fr>
1532 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1533 * src/conflicts.c: Use it.
1534 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1535 incorrectly ``simplified''.
1537 2001-12-05 Akim Demaille <akim@epita.fr>
1539 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1540 using the good o' techniques: arrays not pointers, variable
1541 locality, BITISSET, RESETBIT etc.
1543 2001-12-05 Akim Demaille <akim@epita.fr>
1545 * src/state.h (SHIFT_SYMBOL): New.

1550 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1551 (print_reductions): De-obfuscate using the good o' techniques:
1552 arrays not pointers, variable locality, BITISSET.
1554 2001-12-05 Akim Demaille <akim@epita.fr>
1556 * src/conflicts.c (print_reductions): Arrays, not pointers.
1559 2001-12-05 Akim Demaille <akim@epita.fr>
1561 * src/conflicts.c (print_reductions): Pessimize, but clarify.

1571 2001-12-05 Akim Demaille <akim@epita.fr>
1573 * src/conflicts.c (print_reductions): Improve variable locality.
1575 2001-12-05 Akim Demaille <akim@epita.fr>

1580 2001-12-05 Akim Demaille <akim@epita.fr>
1582 * src/LR0.c (augment_automaton): Formatting changes.
1583 Better variable locality.

1588 (transpose): Use it.
1589 Use arrays instead of pointers.
1591 2001-12-05 Akim Demaille <akim@epita.fr>
1593 * src/lalr.c (maxrhs): Move to...
1594 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1595 * src/lalr.c (build_relations): Adjust.
1597 2001-12-05 Akim Demaille <akim@epita.fr>
1599 * src/lalr.c (transpose): Free the memory allocated to the
1600 argument, as it is replaced by the results by the unique caller.
1601 (build_relations): Merely invoke transpose: it handles the memory
1603 Improve variable locality.
1604 Avoid variables used as mere abbreviations.
1605 (compute_lookaheads): Use arrays instead of pointers.
1607 2001-12-05 Akim Demaille <akim@epita.fr>
1609 * src/lalr.c (initialize_F): Improve variable locality.
1610 Avoid variables used as mere abbreviations.

1614 * src/derives.c (print_derives): Display the ruleno.
1615 * src/lalr.c (initialize_F, transpose): Better variable locality
1616 to improve readability.
1617 Avoid variables used as mere abbreviations.
1619 2001-12-05 Akim Demaille <akim@epita.fr>
1621 * src/lalr.c (traverse): Use arrays instead of pointers.
1623 2001-12-05 Akim Demaille <akim@epita.fr>
1625 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1626 the handling of squeue.
1627 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1629 2001-12-05 Akim Demaille <akim@epita.fr>
1631 Because useless nonterminals are now kept alive (instead of being
1632 `destroyed'), we now sometimes examine them, and store information
1633 related to them. Hence we need to know their number, and adjust
1636 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1638 * src/LR0.c (allocate_itemsets): The memory allocated to
1639 `symbol_count' was used for two different purpose: once to count
1640 the number of occurrences of each symbol, and later reassigned to
1641 `shift_symbol', containing the symbol that can be shifted from a
1643 Deobfuscate, i.e., allocate, use and free `symbol_count' here
1645 (new_itemsets): Allocate `shift_symbol' here.
1646 (allocate_itemsets): symbol_count includes useless nonterminals.
1648 (free_storage): Use `free', not `XFREE', for pointers that cannot
1651 2001-12-05 Akim Demaille <akim@epita.fr>
1653 * src/nullable.c (set_nullable): Deobfuscate the handling of
1655 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1657 2001-12-05 Akim Demaille <akim@epita.fr>
1659 * src/gram.c, src/gram.h (ritem_print): New.
1660 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1661 (This useless function was defined only to work around VMS linkers
1662 that can't handle compilation units with variables only).
1663 * src/reduce.c (dump_grammar): Use it to trace the construction of
1666 2001-12-04 Paul Eggert <eggert@twinsun.com>
1668 * src/bison.simple (union yyalloc): Change member names
1669 to be the same as the stack names.
1670 (yyparse): yyptr is now union yyalloc *, not char *.
1671 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
1672 and may generate better code on some machines.
1673 (yystpcpy): Use prototype if __STDC__ is defined, not just
1674 if __cplusplus is defined.
1676 2001-11-30 Akim Demaille <akim@epita.fr>

1723 they all begin with 'yy'.
1725 (yystrlen, yystpcpy): New functions.
1727 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1730 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
1731 instead of relying on string.h functions. Use YYSTACK_ALLOC
1732 and YYSTACK_FREE instead of malloc and free.
1734 2001-11-30 Akim Demaille <akim@epita.fr>
1736 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1737 before their first uses.

1749 2001-11-30 Akim Demaille <akim@epita.fr>
1751 Instead of mapping the LHS of unused rules to -1, keep the LHS
1752 valid, but flag the rules as invalid.

1755 * src/print.c (print_grammar): Adjust.

1788 (union yyalloc): New type.
1789 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1790 an arbitrary restriction on hosts where size_t is wider than int.
1792 (yyparse): Don't dump core if alloca or malloc fails; instead, report
1793 a parser stack overflow. Allocate just one block of memory for all
1794 three stacks, instead of allocating three blocks; this typically is
1795 faster and reduces fragmentation.
1797 Do not limit the number of items in the stack to a value that fits
1798 in 'int', as this is an arbitrary limit on hosts with 64-bit
1799 size_t and 32-bit int.
1801 2001-11-29 Marc Autret <autret_m@epita.fr>
1803 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

3851 argument `data' for consistency with the prototypes.
3853 (obstack_copy, obstack_copy0): Rename the second argument as

3884 (output_files): this.
3886 * src/main.c (main): Don't use `atexit' to register `done', since
3887 it no longer has to remove tmp files, just call `output_files'
3888 when there are no errors.
3890 2000-11-02 Akim Demaille <akim@epita.fr>
3892 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3991 2000-10-04 Akim Demaille <akim@epita.fr>
3993 When a literal string is used to define two different tokens,
3994 `bison -v' segfaults.
3995 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3997 * tests/regression.m4: New file.
3998 Include the core of the sample provided by Piotr Gackiewicz.

4022 translation, move some `\n' out of the translated strings.
4024 2000-10-02 Akim Demaille <akim@epita.fr>
4026 The location tracking mechanism is precious for parse error
4027 messages. Nevertheless, it is enabled only when `@n' is used in
4028 the grammar, which is a different issue (you can use it in error
4029 message, but not in the grammar per se). Therefore, there should
4030 be another means to enable it.
4032 * src/getargs.c (getargs): Support `--locations'.
4034 * src/getargs.h (locationsflag): Export it.
4035 * src/lex.c (percent_table): Support `%locations'.

4047 2000-10-02 Akim Demaille <akim@epita.fr>
4049 Also test parse error messages, including with YYERROR_VERBOSE.
4051 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4053 Use it to check the computations.
4054 Use it to check `nonassoc' is honored.
4055 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4056 `--yyerror-verbose'.

4058 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4060 2000-10-02 Akim Demaille <akim@epita.fr>
4062 Test also `--verbose', `--defines' and `--name-prefix'. Testing
4063 the latter demonstrates a flaw in the handling of non debugging
4064 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4065 was used in order to simplify:
4081 unfortunately this leads to a CPP conflict when
4082 `--name-prefix=foo' is used since it produces `#define yydebug
4085 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4086 (YYDPRINTF): New macro.
4088 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4090 Also test `--verbose', `--defines' and `--name-prefix'.

4094 Improve the readability of the produced parsers.
4096 * src/bison.s1: Formatting changes.
4097 Improve the comment related to the `$' mark.
4098 (yydefault): Don't fall through to `yyresume': `goto' there.
4099 * src/output.c (output_parser): When the `$' is met, skip the end
4101 New variable, `number_of_dollar_signs', to check there's exactly
4102 one `$' in the parser skeleton.
4104 2000-10-02 Akim Demaille <akim@epita.fr>
4106 * lib/xstrdup.c: New file, from the fileutils.

4109 instead of strlen + xmalloc + strcpy.
4110 * src/symtab.c (copys): Remove, use xstrdup instead.
4112 2000-10-02 Akim Demaille <akim@epita.fr>
4114 * src/gram.h (associativity): New enum type which replaces the
4115 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4116 `right_assoc', `left_assoc' and `non_assoc'.
4117 Adjust all dependencies.
4118 * src/reader.c: Formatting changes.
4119 (LTYPESTR): Don't define it, use it as a literal in
4120 `reader_output_yylsp'.
4121 * src/symtab.h (symbol_class): New enum type which replaces the
4122 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

4128 (yaccflag): for consistency and accuracy.
4129 Adjust dependencies.
4131 2000-10-02 Akim Demaille <akim@epita.fr>
4133 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4134 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
4135 difficult and introduced a lot of core dump. It turns out that
4136 Bison used an implementation of `xmalloc' based on `calloc', and
4137 at various places it does depend upon the initialization to 0. I
4138 have not tried to isolate the pertinent places, and all the former
4139 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
4140 someone should address this issue.
4142 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

4243 `user_toknums' is output as a `short[]' in `output.c', while it is
4244 defined as a `int[]' in `reader.c'. For consistency with the
4245 other output tables, `user_toknums' is now defined as a table of

4549 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

5222 * src/reader.c (reader_output_yylsp):
5224 (readgram): Use `#if 0' around code that accepted %command
5225 inside grammar rules: The documentation doesn't allow it,
5226 and it will fail since the %command processors scan for the next %.

5228 declaration to allow a multi-character symbol as an alias.
5229 (parse_thong_decl): New function.
5230 (read_declarations): Added %thong declarations.

5240 Revised and use multiple warnxxx functions to avoid using VARARGS1.
5241 (read_declarations): Improve the error message for
5242 an invalid character. Do not abort.
5243 (read_declarations, copy_guard, copy_action): Use
5244 printable_version to avoid unprintable characters in printed output.
5245 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
5246 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):

5270 (lex): Use literalchar.
5271 (lex): Implemented "..." tokens.

5273 always contain the token. This includes growing the token
5274 buffer while reading an integer.
5275 (parse_percent_token): Replaced if-else statement with percent_table.
5276 (parse_percent_token): Added % declarations as another
5277 way to specify the flags -n, -l, and -r. Also added hooks for
5278 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
5279 major changes to files.c.
5280 (lex) Retain in the incoming stream a character following
5282 (skip_white_space, lex): Revised most error messages
5283 and changed fatal to warn to avoid aborting.
5284 (percent_table): Added %thong declarations.
