1 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
3 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
5 (yy::b4_name::parse): Build verbose error messages, and use error_.
7 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
9 * data/bison.c++: Fix m4 quoting in comments.
11 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
13 * data/bison.c++: Adjust the parser code. Fix some muscles that were
16 2002-02-05 Akim Demaille <akim@epita.fr>
18 * data/bison.c++: Adjust to the M4 back end.
19 More is certainly needed.
21 2002-02-05 Akim Demaille <akim@epita.fr>
23 Give a try to M4 as a back end.
25 * lib/readpipe.c: New, from wdiff.
26 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
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
38 (output_skeleton): Don't look for the skeleton location, let m4 do
40 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
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
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.
58 2002-02-05 Akim Demaille <akim@epita.fr>
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.
64 2002-02-05 Akim Demaille <akim@epita.fr>
66 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
69 2002-02-05 Akim Demaille <akim@epita.fr>
71 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
74 2002-01-29 Paul Eggert <eggert@twinsun.com>
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).
80 2002-01-27 Akim Demaille <akim@epita.fr>
82 Fix `%nonassoc and eof'.
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);
88 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
90 * tests/regression.at (%nonassoc and eof): Adjust to newest
91 Autotest: `.' is not in the PATH.
93 2002-01-27 Akim Demaille <akim@epita.fr>
95 * tests/sets.at (AT_EXTRACT_SETS): New.
99 2002-01-26 Akim Demaille <akim@epita.fr>
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.
105 2002-01-25 Akim Demaille <akim@epita.fr>
107 * tests/regression.at (%nonassoc and eof): New.
108 Suggested by Robert Anisko.
110 2002-01-24 Akim Demaille <akim@epita.fr>
112 Bison dumps core when trying to complain about broken input files.
113 Reported by Cris van Pelt.
115 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
116 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
118 (Invalid inputs): Strengthen: exercise parse_percent_token.
120 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
122 * src/Makefile.am: Add bison.c++.
123 * src/bison.c++: New skeleton.
125 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
129 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
131 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
133 2002-01-20 Marc Autret <marc@gnu.org>
135 * src/files.c (compute_output_file_names): Fix
137 2002-01-20 Marc Autret <marc@gnu.org>
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.
144 2002-01-20 Marc Autret <marc@gnu.org>
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.
150 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
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).
157 2002-01-11 Akim Demaille <akim@epita.fr>
159 * configure.in: Use AC_FUNC_STRNLEN.
160 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
162 2002-01-09 Akim Demaille <akim@epita.fr>
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
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.
176 2002-01-09 Akim Demaille <akim@epita.fr>
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.
184 2002-01-08 Akim Demaille <akim@epita.fr>
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.
193 2002-01-08 Akim Demaille <akim@epita.fr>
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
201 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
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.
209 2002-01-06 Akim Demaille <akim@epita.fr>
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.
217 2002-01-06 Akim Demaille <akim@epita.fr>
219 Bison is dead wrong in its RR conflict reports.
221 * tests/torture.at (GNU Cim Grammar): New.
222 * src/conflicts.c (count_rr_conflicts): Fix.
224 2002-01-06 Akim Demaille <akim@epita.fr>
226 Creating package.m4 from configure.ac causes too many problems.
228 * tests/Makefile.am (package.m4): Create it by hand,
229 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
231 2002-01-06 Akim Demaille <akim@epita.fr>
233 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
236 2002-01-04 Paul Eggert <eggert@twinsun.com>
238 * doc/bison.texinfo (Debugging):
239 Remove YYSTDERR; it's no longer defined or used.
240 Also, s/cstdio.h/cstdio/.
242 2002-01-03 Akim Demaille <akim@epita.fr>
244 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
246 2002-01-03 Akim Demaille <akim@epita.fr>
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
252 2002-01-03 Akim Demaille <akim@epita.fr>
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/.
261 2002-01-03 Akim Demaille <akim@epita.fr>
263 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
264 for non system headers.
266 2002-01-02 Akim Demaille <akim@epita.fr>
268 Equip the skeleton chain with location tracking, runtime trace,
269 pure parser and scanner.
271 * src/parse-skel.y: Request a pure parser, locations, and prefix
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...
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.
283 2001-12-30 Akim Demaille <akim@epita.fr>
285 * src/parse-skel.y: Get rid of the shift/reduce conflict:
286 replace `gb' with BLANKS.
287 * src/scan-skel.l: Adjust.
289 2001-12-30 Akim Demaille <akim@epita.fr>
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
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.
302 2001-12-30 Akim Demaille <akim@epita.fr>
304 * src/skeleton.h: New.
305 * src/output.c (output_parser, output_master_parser): Remove, dead
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.
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'.
319 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
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...
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
332 * src/files.h (strsuffix, stringappend): Add declarations.
333 (tab_extension): Add declaration.
334 (short_base_name): Add declaration.
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
342 (short_base_name): No longer static.
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.
350 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
352 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
355 * src/parse-skel.y: New file.
356 * src/scan-skel.l: New file.
358 2001-12-29 Akim Demaille <akim@epita.fr>
360 %name-prefix is broken.
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
367 Renaming yylval but not yylloc is not consistent. Now we do.
369 * src/bison.simple: Prefix yylloc if used.
370 * doc/bison.texinfo (Decl Summary): Document that.
372 2001-12-29 Akim Demaille <akim@epita.fr>
374 * doc/bison.texinfo: Promote `%long-directive' over
376 Remove all references to fixed-output-files, yacc is enough.
378 2001-12-29 Akim Demaille <akim@epita.fr>
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.
385 2001-12-29 Akim Demaille <akim@epita.fr>
387 * src/output.c (header_output): Don't forget to export YYLTYPE and
389 * tests/headers.at (export YYLTYPE): New, make sure it does.
390 * tests/regression.at (%union and --defines, Invalid CPP headers):
392 * tests/headers.at: here.
394 2001-12-29 Akim Demaille <akim@epita.fr>
396 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
398 2001-12-29 Akim Demaille <akim@epita.fr>
400 * tests/actions.at (Mid-rule actions): Output on a single line
403 2001-12-29 Akim Demaille <akim@epita.fr>
405 * doc/bison.texinfo: Formatting changes.
407 2001-12-29 Akim Demaille <akim@epita.fr>
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.
412 * src/output.c (token_definitions_output): New.
413 (output_parser, header_output): Use it.
414 * src/reader.c (symbols_save): Remove.
416 2001-12-29 Akim Demaille <akim@epita.fr>
418 * src/bison.simple: Do not provide a default for YYSTYPE and
419 YYLTYPE before the user's prologue. Otherwise it's hardly... a
422 2001-12-29 Akim Demaille <akim@epita.fr>
424 Mid-rule actions are simply... ignored!
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
429 * tests/actions.at (Mid-rule actions): New.
431 2001-12-29 Akim Demaille <akim@epita.fr>
435 * src/reader.c (reader): Free grammar.
437 2001-12-29 Akim Demaille <akim@epita.fr>
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.
445 2001-12-29 Akim Demaille <akim@epita.fr>
447 * src/options.h, src/options.c (create_long_option_table): Rename
449 (long_option_table_new): this, with a clearer prototype.
450 (percent_table): Remove, unused,
451 * src/getargs.c (getargs): Adjust.
453 2001-12-29 Akim Demaille <akim@epita.fr>
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
459 2001-12-29 Akim Demaille <akim@epita.fr>
461 * src/lalr.c (build_relations): Rename `states' as `states1'.
462 Sorry, I don't understand exactly what it is, no better name...
464 2001-12-29 Akim Demaille <akim@epita.fr>
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
471 2001-12-29 Akim Demaille <akim@epita.fr>
473 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
476 2001-12-29 Akim Demaille <akim@epita.fr>
478 * src/reader.c, src/reader.h (user_toknums): Remove.
479 Adjust all users to use symbols[i]->user_token_number.
481 2001-12-29 Akim Demaille <akim@epita.fr>
483 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
484 Adjust all users to use symbols[i]->prec or ->assoc.
486 2001-12-29 Akim Demaille <akim@epita.fr>
488 * src/reader.c, src/reader.h (tags): Remove.
489 Adjust all users to use symbols[i]->tag.
491 2001-12-29 Akim Demaille <akim@epita.fr>
493 * src/gram.h, src/gram.c (symbols): New, similar to state_table
495 * src/reader.c (packsymbols): Fill this table.
497 * src/conflicts.c (resolve_sr_conflict): Adjust.
498 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
500 Use symbols[i]->tag instead of tags[i].
502 2001-12-29 Akim Demaille <akim@epita.fr>
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.
508 2001-12-29 Akim Demaille <akim@epita.fr>
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
517 2001-12-29 Akim Demaille <akim@epita.fr>
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.
524 2001-12-29 Akim Demaille <akim@epita.fr>
526 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
527 visible, and some states have now a different number.
529 2001-12-29 Akim Demaille <akim@epita.fr>
531 * src/reader.c (readgram): Bind the initial rule's lineno to that
533 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
534 (Solved SR Conflicts): Adjust rule 0's line number.
536 2001-12-29 Akim Demaille <akim@epita.fr>
538 Fix the `GAWK Grammar' failure.
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
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.
549 2001-12-29 Akim Demaille <akim@epita.fr>
551 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
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
558 2001-12-29 Akim Demaille <akim@epita.fr>
560 * src/lalr.c (lookaheads_print): New.
561 (lalr): Call it when --trace-flag.
562 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
565 2001-12-29 Akim Demaille <akim@epita.fr>
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.
577 2001-12-29 Akim Demaille <akim@epita.fr>
579 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
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.
587 2001-12-29 Akim Demaille <akim@epita.fr>
589 * src/output.c: Comment changes.
591 2001-12-27 Paul Eggert <eggert@twinsun.com>
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.
598 Also, catch up with 1.31's YYSTD.
600 2001-12-27 Akim Demaille <akim@epita.fr>
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
611 2001-12-27 Akim Demaille <akim@epita.fr>
613 * tests/regression.at (Unresolved SR Conflicts):
614 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
617 2001-12-27 Akim Demaille <akim@epita.fr>
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
631 * src/reader.c (readgram): Once the grammar read, insert the rule
632 0: `$axiom: START-SYMBOL $'.
633 * tests/set.at: Adjust: rule 0 is now displayed, and since the
634 number of the states has changed (the final state is no longer
635 necessarily the last), catch up.
637 2001-12-27 Akim Demaille <akim@epita.fr>
639 Try to make the use of the eoftoken valid. Given that its value
640 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
641 is used instead of > 0 where appropriate, (ii), depend upon nritems
642 instead of the 0-sentinel.
644 * src/gram.h, src/gram.c (nritems): New.
645 Expected to be duplication of nitems, but for the time being...
646 * src/reader.c (packgram): Assert nritems and nitems are equal.
647 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
648 * src/closure.c (print_closure, print_fderives): Likewise.
649 * src/gram.c (ritem_print): Likewise.
650 * src/print.c (print_core, print_grammar): Likewise.
651 * src/print_graph.c: Likewise.
653 2001-12-27 Akim Demaille <akim@epita.fr>
655 * src/main.c (main): If there are complains after grammar
656 reductions, then output the report anyway if requested, then die.
657 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
658 * src/reader.c (eoftoken): New.
659 (parse_token_decl): If the token being defined has value `0', it
661 (packsymbols): No longer hack `tags' to insert `$' 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.
671 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
673 2001-12-27 Akim Demaille <akim@epita.fr>
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
680 * src/reader.c (symbols_save): Use strchr.
682 2001-12-27 Akim Demaille <akim@epita.fr>
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
688 Prefer high to wide: output the state number on a line of its own.
690 2001-12-27 Akim Demaille <akim@epita.fr>
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.
700 2001-12-27 Akim Demaille <akim@epita.fr>
702 * src/state.h, src/state.c (errs_new, errs_dup): New.
703 * src/LR0.c (set_state_table): Let all the states have an errs,
704 even if reduced to 0.
705 * src/print.c (print_errs, print_reductions): Adjust.
706 * src/output.c (output_actions, action_row): Adjust.
707 * src/conflicts.c (resolve_sr_conflict): Adjust.
709 2001-12-27 Akim Demaille <akim@epita.fr>
711 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
713 2001-12-27 Akim Demaille <akim@epita.fr>
715 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
717 (lookaheadset, shiftset): New, used as additional storage by
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.
724 2001-12-27 Akim Demaille <akim@epita.fr>
726 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
729 2001-12-27 Akim Demaille <akim@epita.fr>
731 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
732 (build_relations): Adjust.
734 2001-12-27 Akim Demaille <akim@epita.fr>

741 * src/reader.c (packgram): Catch nitems overflows.
743 2001-12-27 Akim Demaille <akim@epita.fr>
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
753 2001-12-27 Akim Demaille <akim@epita.fr>
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
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
765 In other words the guard is just explicitly optional.
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
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

783 * src/reader.c (symbol_list_new): Be sure to initialize all the
786 2001-12-27 Akim Demaille <akim@epita.fr>
788 All the hacks using a final pseudo state are now useless.
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).
795 2001-12-27 Akim Demaille <akim@epita.fr>
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
801 2001-12-27 Akim Demaille <akim@epita.fr>
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)

821 * src/bison.hairy: Formatting/comment changes.
823 Remove `register' indications.
824 Add plenty of `static'.
826 2001-12-27 Akim Demaille <akim@epita.fr>
828 * src/output.c (prepare): Drop the muscle `ntbase' which
830 * src/bison.simple: Formatting/comment changes.
831 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
832 is an undocumented synonym.
834 2001-12-22 Akim Demaille <akim@epita.fr>
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
839 Reported by Wayne Green.
841 2001-12-22 Akim Demaille <akim@epita.fr>
843 Some actions of web2c.y are improperly triggered.
844 Reported by Mike Castle.
846 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

848 (Web2c Report): this.
849 (Web2c Actions): New.
851 2001-12-22 Akim Demaille <akim@epita.fr>
853 Reductions in web2c.y are improperly reported.
854 Reported by Mike Castle.
856 * src/conflicts.c (print_reductions): Fix.
857 * tests/regression.at (Web2c): New.
859 2001-12-18 Akim Demaille <akim@epita.fr>
861 Some host fail on `assert (!"foo")', which expands to
862 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
863 Reported by Nelson Beebee.
865 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
866 `#define it_succeeded 0' and `assert (it_succeeded)'.
868 2001-12-17 Marc Autret <autret_m@epita.fr>
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).
874 2001-12-17 Paul Eggert <eggert@twinsun.com>
876 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
877 YYDEBUG must be defined to a nonzero value.
879 * src/bison.simple (yytname): Do not assume that the user defines
880 YYDEBUG to a properly parenthesized expression.
882 2001-12-17 Akim Demaille <akim@epita.fr>
884 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
885 nlookaheads is a new member.
887 * src/lalr.h (nlookaheads): Remove this orphan declaration.
888 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
891 2001-12-17 Akim Demaille <akim@epita.fr>
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,
896 * src/reader.c (reader): Do it.
898 2001-12-17 Akim Demaille <akim@epita.fr>
900 * src/conflicts.c (print_reductions): Formatting changes.
902 2001-12-17 Akim Demaille <akim@epita.fr>
904 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
906 (resolve_sr_conflict): Adjust.
908 2001-12-17 Akim Demaille <akim@epita.fr>
910 * src/output.c (output_obstack): Be static and rename as...
911 (format_obstack): this, to avoid any confusion with files.c's
913 * src/reader.h (muscle_obstack): Move to...
914 * src/output.h: here, since it's defined in output.c.
916 2001-12-17 Akim Demaille <akim@epita.fr>
918 * src/output.c (action_row, save_column, default_goto)
919 (sort_actions, matching_state, pack_vector): Better variable
922 2001-12-17 Akim Demaille <akim@epita.fr>
924 * src/output.c: Various formatting changes.
926 2001-12-17 Akim Demaille <akim@epita.fr>
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.
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.
939 2001-12-16 Marc Autret <autret_m@epita.fr>
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
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.
951 2001-12-15 Marc Autret <autret_m@epita.fr>
953 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
955 2001-12-15 Marc Autret <autret_m@epita.fr>
957 * src/output.c (output_gram): Keep track of the hairy one.
959 2001-12-15 Akim Demaille <akim@epita.fr>
961 Make `make distcheck' work.
963 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
964 system.h which uses libgettext.h.
966 2001-12-15 Akim Demaille <akim@epita.fr>
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.
973 2001-12-15 Akim Demaille <akim@epita.fr>
975 The header can also be produced directly, without any obstack!
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
984 (output_token_translations): Merge into...
985 (symbols_output): this.
987 (symbols_save): this.
989 * src/output.c (header_output): New.
992 2001-12-15 Akim Demaille <akim@epita.fr>
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.
1000 (copy_comment): this.
1002 2001-12-15 Akim Demaille <akim@epita.fr>
1004 * src/lex.c, src/lex.h (xgetc): No longer static.
1005 * src/reader.c (parse_union_decl): Revamp.
1007 2001-12-15 Akim Demaille <akim@epita.fr>
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.
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.
1019 2001-12-15 Akim Demaille <akim@epita.fr>
1021 Attach actions to rules, instead of pre-outputting them to
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.
1032 (prepare): Don't save the `action' muscle.
1033 * src/bison.simple: s/%%action/%%actions/.
1035 2001-12-15 Akim Demaille <akim@epita.fr>
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.
1041 2001-12-14 Akim Demaille <akim@epita.fr>
1043 * src/lex.c (literalchar): Simply return the char you decoded, non
1044 longer mess around with obstacks and int pointers.
1047 2001-12-14 Akim Demaille <akim@epita.fr>
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
1055 2001-12-13 Paul Eggert <eggert@twinsun.com>
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.
1062 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1064 2001-12-13 Akim Demaille <akim@epita.fr>
1066 The computation of nullable is broken: it doesn't handle empty
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.
1074 Work around Autotest bugs.
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
1084 * tests/sets.at: here.
1086 2001-12-13 Akim Demaille <akim@epita.fr>
1088 * src/closure.c (closure): Use nrules instead of playing tricks
1091 2001-12-13 Akim Demaille <akim@epita.fr>
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
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.
1105 2001-12-13 Akim Demaille <akim@epita.fr>
1107 * src/reader.c (readgram): Remove dead code, an strip useless
1109 (get_type): Remove, unused.
1111 2001-12-12 Akim Demaille <akim@epita.fr>
1113 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1114 on that of lib/error.c.
1116 2001-12-12 Akim Demaille <akim@epita.fr>
1118 Some hosts don't like `/' in includes.
1120 * src/system.h: Include libgettext.h without qualifying the path.
1121 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1124 2001-12-11 Marc Autret <autret_m@epita.fr>
1126 * src/output.c (output_parser): Remove useless muscle.
1128 2001-12-11 Marc Autret <autret_m@epita.fr>
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.
1135 2001-12-10 Marc Autret <autret_m@epita.fr>
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.
1142 2001-12-10 Marc Autret <autret_m@epita.fr>
1144 * src/reader.c (symbols_output): Clean up.
1145 * src/output.c (output_gram, output): Clean up.
1147 2001-12-10 Akim Demaille <akim@epita.fr>
1149 * src/lalr.c (initialize_lookaheads): New. Extracted from...
1150 * src/LR0.c (set_state_table): here.
1151 * src/lalr.c (lalr): Call it.
1153 2001-12-10 Akim Demaille <akim@epita.fr>
1155 * src/state.h (shifts): Remove the `number' member: shifts are
1156 attached to state, hence no longer need to be labelled with a
1159 2001-12-10 Akim Demaille <akim@epita.fr>
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.
1164 * src/state.h (shifts): Remove the `next' member.
1165 * src/LR0.c (first_state, last_state): Remove.
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.
1172 2001-12-10 Akim Demaille <akim@epita.fr>
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.
1179 2001-12-10 Akim Demaille <akim@epita.fr>
1181 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1182 only when appropriate: when insert_start_shifting_state' is not
1184 * tests/regression.at (Rule Line Numbers): Adjust.
1186 2001-12-10 Akim Demaille <akim@epita.fr>
1188 * src/LR0.c (augment_automaton): Now that all states have shifts,
1189 merge the two cases addition shifts to the initial state.
1191 2001-12-10 Akim Demaille <akim@epita.fr>
1193 * src/lalr.c (set_state_table): Move to...
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.
1199 2001-12-10 Akim Demaille <akim@epita.fr>
1201 * src/LR0.h (first_shift, first_reduction): Remove.
1202 * src/lalr.c: Don't use first_shift: find shifts through the
1205 2001-12-10 Akim Demaille <akim@epita.fr>
1207 * src/LR0.c: Attach shifts to states as soon as they are
1209 * src/lalr.c (set_state_table): Instead of assigning shifts to
1210 state, just assert that the mapping was properly done.
1212 2001-12-10 Akim Demaille <akim@epita.fr>
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!
1224 2001-12-10 Akim Demaille <akim@epita.fr>
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?
1234 2001-12-10 Akim Demaille <akim@epita.fr>
1236 * src/muscle_tab.c (muscle_init): NULL is a better default than
1239 2001-12-10 Akim Demaille <akim@epita.fr>
1241 * src/reader.c (reader): Calling symbols_output once is enough.
1243 2001-12-10 Akim Demaille <akim@epita.fr>
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
1249 * src/state.h (struct reductions): Remove member `number' and
1251 * src/LR0.c (first_reduction, last_reduction): Remove.
1252 (save_reductions): Don't link the new reductions, store them in
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
1260 2001-12-10 Akim Demaille <akim@epita.fr>
1262 * src/options.c (OPTN, DRTV, BOTH): New.
1263 (option_table): Use them.
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
1270 2001-12-10 Akim Demaille <akim@epita.fr>
1272 * src/output.c (output, prepare): Make sure the values of the
1273 muscles `action' and `prologue' are 0-terminated.
1275 2001-12-10 Akim Demaille <akim@epita.fr>
1277 Clean up GCC warnings.
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.
1287 2001-12-10 Akim Demaille <akim@epita.fr>
1289 * configure.in: Require 2.52g.
1290 M4 is not needed, but AUTOM4TE is.
1292 * tests/Makefile.am: Adjust.
1294 2001-12-10 Akim Demaille <akim@epita.fr>
1296 One structure for states is enough, even though theoretically
1297 there are LR(0) states and LALR(1) states.
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
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.
1310 2001-12-10 Akim Demaille <akim@epita.fr>
1312 Bison dumps core on bash.y.
1313 Reported by Pascal Bart.
1315 * src/warshall.c (bitmatrix_print): New.
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.
1321 2001-12-05 Akim Demaille <akim@epita.fr>
1323 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1325 Reported by Peter Hámorský.

1330 (resolve_sr_conflict): Adjust.
1331 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1333 (state_t.reductions, state_t.shifts): this.
1335 2001-12-05 Akim Demaille <akim@epita.fr>
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.
1344 2001-12-05 Akim Demaille <akim@epita.fr>
1346 * src/output.c (pack_vector): Use assert, not berror.
1347 * src/main.c (berror): Remove, unused.
1349 2001-12-05 Akim Demaille <akim@epita.fr>
1351 New experimental feature: if --verbose --trace output all the
1352 items of a state, not only its kernel.
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.
1359 2001-12-05 Akim Demaille <akim@epita.fr>
1361 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1362 * src/closure.c, src/closure.h (itemsetsize): Rename as...

1368 (closure): Use it for printing input and output.
1370 2001-12-05 Akim Demaille <akim@epita.fr>
1372 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1373 indexed by nonterminals.
1375 2001-12-05 Akim Demaille <akim@epita.fr>
1377 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

1397 locality, BITISSET, RESETBIT etc.
1399 2001-12-05 Akim Demaille <akim@epita.fr>
1401 Pessimize the code to simplify it: from now on, all the states
1402 have a valid SHIFTS, which NSHIFTS is possibly 0.
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,

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''.

1418 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1419 using the good o' techniques: arrays not pointers, variable

1476 2001-12-05 Akim Demaille <akim@epita.fr>
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
1482 Improve variable locality.
1483 Avoid variables used as mere abbreviations.
1484 (compute_lookaheads): Use arrays instead of pointers.
1486 2001-12-05 Akim Demaille <akim@epita.fr>

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'.
1508 2001-12-05 Akim Demaille <akim@epita.fr>
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
1515 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
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
1522 Deobfuscate, i.e., allocate, use and free `symbol_count' here
1524 (new_itemsets): Allocate `shift_symbol' here.
1525 (allocate_itemsets): symbol_count includes useless nonterminals.
1527 (free_storage): Use `free', not `XFREE', for pointers that cannot
1530 2001-12-05 Akim Demaille <akim@epita.fr>
1532 * src/nullable.c (set_nullable): Deobfuscate the handling of
1534 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.

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
1545 2001-12-04 Paul Eggert <eggert@twinsun.com>
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.
1555 2001-11-30 Akim Demaille <akim@epita.fr>
1557 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1558 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU

1561 Include WARNING_CFLAGS here.
1562 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

1567 * lib/quotearg.h (quotearg_n, quotearg_n_style):
1568 First arg is int, not unsigned.
1569 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
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.
1576 2001-11-29 Paul Eggert <eggert@twinsun.com>
1578 Name space cleanup in generated parser.
1580 * doc/bison.texinfo (Bison Parser): Discuss system headers
1581 and their effect on the user name space.
1584 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

1586 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1588 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
1589 on user names when possible.
1591 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1592 Simplify test for whather <alloca.h> exists.
1594 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1596 (<stdio.h>): Include if YYDEBUG.
1598 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
1599 ! defined (yyoverflow) && ! defined (yymemcpy).
1601 (yymemcpy, yyparse): Rename local variables as needed so that
1602 they all begin with 'yy'.
1604 (yystrlen, yystpcpy): New functions.
1606 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
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.
1613 2001-11-30 Akim Demaille <akim@epita.fr>
1615 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1616 before their first uses.

1625 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1626 if body instead of `;' to pacify GCC's warnings.
1628 2001-11-30 Akim Demaille <akim@epita.fr>
1630 Instead of mapping the LHS of unused rules to -1, keep the LHS
1631 valid, but flag the rules as invalid.
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.

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.
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.
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.

3836 2000-10-16 Akim Demaille <akim@epita.fr>
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.
3844 2000-10-16 Akim Demaille <akim@epita.fr>
3846 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

3856 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
3857 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:
3858 New files, from Fileutils 4.0.27.
3859 * src/main.c (printable_version): Remove.
3860 * src/lex.c, src/reader.c: Use `quote'.
3862 2000-10-04 Akim Demaille <akim@epita.fr>

3866 2000-10-04 Akim Demaille <akim@epita.fr>
3868 * doc/bison.texinfo: Various typos spotted by Neil Booth.
3870 2000-10-04 Akim Demaille <akim@epita.fr>
3872 When a literal string is used to define two different tokens,
3873 `bison -v' segfaults.
3874 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
3876 * tests/regression.m4: New file.
3877 Include the core of the sample provided by Piotr Gackiewicz.
3878 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
3881 2000-10-04 Akim Demaille <akim@epita.fr>
3883 * src/reader.c (parse_expect_decl): Keep `count' within the size
3887 2000-10-02 Paul Eggert <eggert@twinsun.com>

3895 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
3898 2000-10-02 Akim Demaille <akim@epita.fr>

3901 translation, move some `\n' out of the translated strings.
3903 2000-10-02 Akim Demaille <akim@epita.fr>
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.
3911 * src/getargs.c (getargs): Support `--locations'.
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'.
3919 * tests/calc.m4: Test it.
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'.
3926 2000-10-02 Akim Demaille <akim@epita.fr>
3928 Also test parse error messages, including with YYERROR_VERBOSE.
3930 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
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'.

3937 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
3939 2000-10-02 Akim Demaille <akim@epita.fr>
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:
3960 unfortunately this leads to a CPP conflict when
3961 `--name-prefix=foo' is used since it produces `#define yydebug
3964 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
3965 (YYDPRINTF): New macro.
3967 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
3969 Also test `--verbose', `--defines' and `--name-prefix'.

3973 Improve the readability of the produced parsers.
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
3980 New variable, `number_of_dollar_signs', to check there's exactly
3981 one `$' in the parser skeleton.
3983 2000-10-02 Akim Demaille <akim@epita.fr>
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.
3991 2000-10-02 Akim Demaille <akim@epita.fr>
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

4007 (yaccflag): for consistency and accuracy.
4008 Adjust dependencies.
4010 2000-10-02 Akim Demaille <akim@epita.fr>
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.
4021 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

4120 2000-10-02 Akim Demaille <akim@epita.fr>
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

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).
4395 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4397 (yyparse): When providing a default semantic action, provide a
4398 default location action.

5087 1995-10-15 Richard Stallman <rms@gnu.org>
5089 * src/vmsgetargs.c, src/getargs.c:
5090 Added -n, -k, and -raw switches.

5094 New #define for adding aliases to %token.
5095 (struct bucket): Added `alias' field.
5097 * src/reduce.c (reduce_grammar):
5098 Revise error message.
5099 (print_notices): Remove final `.' from error message.
5101 * src/reader.c (reader_output_yylsp):
5103 (readgram): Use `#if 0' around code that accepted %command
5104 inside grammar rules: The documentation doesn't allow it,
5105 and it will fail since the %command processors scan for the next %.
5106 (parse_token_decl): Extended the %token
5107 declaration to allow a multi-character symbol as an alias.
5108 (parse_thong_decl): New function.
5109 (read_declarations): Added %thong declarations.
5110 (read_declarations): Handle NOOP to deal with allowing
5111 % declarations as another means to specify the flags.
5112 (readgram): Allow %prec prior to semantics embedded in a rule.
5113 (skip_to_char, read_declarations, copy_definition)
5114 (parse_token_decl, parse_start_decl, parse_type_decl)
5115 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
5116 (get_type_name, copy_guard, copy_action, readgram)
5117 (get_type, packsymbols): Revised most error messages.
5118 Changed `fatal' to `warnxxx' to avoid aborting for error.
5119 Revised and use multiple warnxxx functions to avoid using VARARGS1.
5120 (read_declarations): Improve the error message for
5121 an invalid character. Do not abort.
5122 (read_declarations, copy_guard, copy_action): Use
5123 printable_version to avoid unprintable characters in printed output.
5124 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
5125 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
5126 Allow the type of a non-terminal can be given
5127 more than once, as long as all specifications give the same type.
5130 (output_headers, output_trailers, output, output_gram)
5131 (output_rule_data): Implement noparserflag variable.
5132 Implement toknumflag variable.
5133 (output): Call reader_output_yylsp to output LTYPESTR.
5135 * src/main.c (main):
5136 If reader sees an error, don't process the grammar.
5137 (fatals): Updated to not use VARARGS1.
5138 (printable_version, int_to_string, warn, warni, warns, warnss)
5139 (warnsss): New error reporting functions. Avoid abort for error.
5142 Added THONG and NOOP for alias processing.
5143 Added SETOPT for the new code that allows setting options with %flags.
5146 Include getopt.h. Add some extern decls.
5147 (safegetc): New function to deal with EOF gracefully.
5148 (literalchar); new function to deal with reading \ escapes.
5149 (lex): Use literalchar.
5150 (lex): Implemented "..." tokens.
5151 (literalchar, lex, parse_percent_token): Made tokenbuffer
5152 always contain the token. This includes growing the token
5153 buffer while reading an integer.
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
5161 (skip_white_space, lex): Revised most error messages
5162 and changed fatal to warn to avoid aborting.
5163 (percent_table): Added %thong declarations.
5165 * src/gram.h: Comment changes.
5167 * src/files.c (openfiles, open_extra_files, done):
5169 and actfile file. Handle noparserflag. Both for -n switch.
