321 to minimize the number of warnings from xgettext.
322 (handle_action_dollar, handle_action_at): Don't use isdigit,
323 as it mishandles negative chars and it may not work as expected
324 outside the C locale.

567 for the time being: %locations ought to provide it to yyerror.
569 2002-07-25 Akim Demaille <akim@epita.fr>
571 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

2943 (prepare): Given that for the time being changesyntax is not
2944 usable in M4, rename the muscles using `-' to `_'.

2977 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

2982 Fix `%nonassoc and eof'.
2984 * src/state.c (errs_dup): Aaaah! The failure was due to bytes

3095 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3096 New, stolen from the Fileutils 4.1.
3097 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3098 * configure.in: Check for the presence of memrchr, and of its
3101 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
3103 * lib/hash.h (__P): Added definition for this macro.
3104 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3105 BUILT_SOURCES, to ensure they are generated first.
3106 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3107 %error-verbose to allow bootstrapping with bison 1.30x.
3109 2002-01-06 Akim Demaille <akim@epita.fr>
3111 * src/reader.c (parse_braces): Don't fetch the next char, the
3112 convention is to fetch on entry.
3113 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3114 'switch' without a following semicolon.
3115 * tests/regression.at (braces parsing): New.
3117 2002-01-06 Akim Demaille <akim@epita.fr>
3119 Bison is dead wrong in its RR conflict reports.
3121 * tests/torture.at (GNU Cim Grammar): New.
3122 * src/conflicts.c (count_rr_conflicts): Fix.
3124 2002-01-06 Akim Demaille <akim@epita.fr>
3126 Creating package.m4 from configure.ac causes too many problems.
3128 * tests/Makefile.am (package.m4): Create it by hand,
3129 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3131 2002-01-06 Akim Demaille <akim@epita.fr>
3133 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3136 2002-01-04 Paul Eggert <eggert@twinsun.com>
3138 * doc/bison.texinfo (Debugging):
3139 Remove YYSTDERR; it's no longer defined or used.
3140 Also, s/cstdio.h/cstdio/.
3142 2002-01-03 Akim Demaille <akim@epita.fr>
3144 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3146 2002-01-03 Akim Demaille <akim@epita.fr>
3148 * src/parse-skel.y (process_skeleton): Don't bind the parser's
3149 tracing code to --trace, wait for a better --trace option, with
3152 2002-01-03 Akim Demaille <akim@epita.fr>
3154 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3155 The ISO C++ standard is extremely clear about it: stderr is
3156 considered a macro, not a regular symbol (see table 94 `Header
3157 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3158 Therefore std:: does not apply to it. It still does with fprintf.
3159 Also, s/cstdio.h/cstdio/.
3161 2002-01-03 Akim Demaille <akim@epita.fr>
3163 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3164 for non system headers.
3166 2002-01-02 Akim Demaille <akim@epita.fr>
3168 Equip the skeleton chain with location tracking, runtime trace,
3169 pure parser and scanner.
3171 * src/parse-skel.y: Request a pure parser, locations, and prefix
3173 (%union): Having several members with the same type does not help
3174 type mismatches, simplify.
3175 (YYPRINT, yyprint): New.
3176 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3179 * src/scan-skel.l: Adjust to these changes.
3180 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3181 (LOCATION_PRINT, skel_control_t): New.
3183 2001-12-30 Akim Demaille <akim@epita.fr>
3185 * src/parse-skel.y: Get rid of the shift/reduce conflict:
3186 replace `gb' with BLANKS.
3187 * src/scan-skel.l: Adjust.
3189 2001-12-30 Akim Demaille <akim@epita.fr>
3191 * src/system.h: We don't need nor want bcopy.
3192 Throw away MS-DOS crap: we don't need getpid.
3193 * configure.in: We don't need strndup. It was even causing
3194 problems: because Flex includes the headers *before* us,
3195 _GNU_SOURCE is not defined by config.h, and therefore strndup was
3197 * lib/xstrndup.c: New.
3198 * src/scan-skel.l: Use it.
3199 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3200 * src/parse-skel.y: Use %directives instead of #defines.
3202 2001-12-30 Akim Demaille <akim@epita.fr>
3204 * src/skeleton.h: New.
3205 * src/output.c (output_parser, output_master_parser): Remove, dead
3207 * src/output.h (get_lines_number, actions_output, guards_output)
3208 (token_definitions_output): Prototype them.
3209 * src/parse-skel.y: Add the license notice.
3210 Include output.h and skeleton.h.
3211 (process_skeleton): Returns void, and takes a single parameter.
3212 * src/scan-skel.l: Add the license notice.
3214 Don't use %option yylineno: it seems that then Flex imagines
3215 REJECT has been used, and therefore it won't reallocate its
3216 buffers (which makes no other sense to me than a bug). It results
3217 in warnings for `unused: yy_flex_realloc'.
3219 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
3221 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3222 (MUSCLE_INSERT_PREFIX): ...to there.
3223 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3224 (MUSCLE_INSERT_PREFIX): Move from here...
3226 * src/bison.hairy: Add a section directive. Put braces around muscle
3227 names. This parser skeleton is still broken, but Bison should not
3228 choke on a bad muscle 'syntax'.
3229 * src/bison.simple: Add a section directive. Put braces around muscle
3232 * src/files.h (strsuffix, stringappend): Add declarations.
3233 (tab_extension): Add declaration.
3234 (short_base_name): Add declaration.
3236 * src/files.c (strsuffix, stringappend): No longer static. These
3237 functions are used in the skeleton parser.
3238 (tab_extension): New.
3239 (compute_base_names): Use the computations done in this function
3240 to guess if the generated parsers should have '.tab' in their
3242 (short_base_name): No longer static.
3244 * src/output.c (output_skeleton): New.
3245 (output): Disable call to output_master_parser, and give a try to
3246 a new skeleton handling system.
3247 (guards_output, actions_output): No longer static.
3248 (token_definitions_output, get_lines_number): No longer static.
3250 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3252 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3255 * src/parse-skel.y: New file.
3256 * src/scan-skel.l: New file.
3258 2001-12-29 Akim Demaille <akim@epita.fr>
3260 %name-prefix is broken.
3262 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3263 Adjust all dependencies.
3264 * tests/headers.at (export YYLTYPE): Strengthen this test: use
3267 Renaming yylval but not yylloc is not consistent. Now we do.
3269 * src/bison.simple: Prefix yylloc if used.
3270 * doc/bison.texinfo (Decl Summary): Document that.
3272 2001-12-29 Akim Demaille <akim@epita.fr>
3274 * doc/bison.texinfo: Promote `%long-directive' over
3276 Remove all references to fixed-output-files, yacc is enough.
3278 2001-12-29 Akim Demaille <akim@epita.fr>
3280 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3281 user prologue. These are defaults.
3282 * tests/actions.at (Mid-rule actions): Make sure the user can
3283 define YYDEBUG and YYERROR_VERBOSE.
3285 2001-12-29 Akim Demaille <akim@epita.fr>
3287 * src/output.c (header_output): Don't forget to export YYLTYPE and
3289 * tests/headers.at (export YYLTYPE): New, make sure it does.
3290 * tests/regression.at (%union and --defines, Invalid CPP headers):
3292 * tests/headers.at: here.
3294 2001-12-29 Akim Demaille <akim@epita.fr>
3296 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3298 2001-12-29 Akim Demaille <akim@epita.fr>
3300 * tests/actions.at (Mid-rule actions): Output on a single line
3303 2001-12-29 Akim Demaille <akim@epita.fr>
3305 * doc/bison.texinfo: Formatting changes.
3307 2001-12-29 Akim Demaille <akim@epita.fr>
3309 Don't store the token defs in a muscle, just be ready to output it
3310 on command. Now possible via `symbols'. Fixes a memory leak.
3312 * src/output.c (token_definitions_output): New.
3313 (output_parser, header_output): Use it.
3314 * src/reader.c (symbols_save): Remove.
3316 2001-12-29 Akim Demaille <akim@epita.fr>
3318 * src/bison.simple: Do not provide a default for YYSTYPE and
3319 YYLTYPE before the user's prologue. Otherwise it's hardly... a
3322 2001-12-29 Akim Demaille <akim@epita.fr>
3324 Mid-rule actions are simply... ignored!
3326 * src/reader.c (readgram): Be sure to attach mid-rule actions to
3327 the empty-rule associated to the dummy symbol, not to the host
3329 * tests/actions.at (Mid-rule actions): New.
3331 2001-12-29 Akim Demaille <akim@epita.fr>
3335 * src/reader.c (reader): Free grammar.
3337 2001-12-29 Akim Demaille <akim@epita.fr>
3341 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3342 since it allocates it for each state, although only one is needed.
3343 (allocate_storage): Do it here.
3345 2001-12-29 Akim Demaille <akim@epita.fr>
3347 * src/options.h, src/options.c (create_long_option_table): Rename
3349 (long_option_table_new): this, with a clearer prototype.
3350 (percent_table): Remove, unused,
3351 * src/getargs.c (getargs): Adjust.
3353 2001-12-29 Akim Demaille <akim@epita.fr>
3355 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3356 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3359 2001-12-29 Akim Demaille <akim@epita.fr>
3361 * src/lalr.c (build_relations): Rename `states' as `states1'.
3362 Sorry, I don't understand exactly what it is, no better name...
3364 2001-12-29 Akim Demaille <akim@epita.fr>
3366 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3367 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3368 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3371 2001-12-29 Akim Demaille <akim@epita.fr>
3373 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3376 2001-12-29 Akim Demaille <akim@epita.fr>
3378 * src/reader.c, src/reader.h (user_toknums): Remove.
3379 Adjust all users to use symbols[i]->user_token_number.
3381 2001-12-29 Akim Demaille <akim@epita.fr>
3383 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3384 Adjust all users to use symbols[i]->prec or ->assoc.
3386 2001-12-29 Akim Demaille <akim@epita.fr>
3388 * src/reader.c, src/reader.h (tags): Remove.
3389 Adjust all users to use symbols[i]->tag.
3391 2001-12-29 Akim Demaille <akim@epita.fr>
3393 * src/gram.h, src/gram.c (symbols): New, similar to state_table
3395 * src/reader.c (packsymbols): Fill this table.
3397 * src/conflicts.c (resolve_sr_conflict): Adjust.
3398 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3400 Use symbols[i]->tag instead of tags[i].
3402 2001-12-29 Akim Demaille <akim@epita.fr>
3404 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3405 In addition, put a comment in there, to replace...
3406 * tests/regression.at (%union and C comments): Remove.
3408 2001-12-29 Akim Demaille <akim@epita.fr>
3410 * tests/regression.at (Web2c Actions): Blindly move the actual
3411 output as expected output. The contents *seem* right to me, but I
3412 can't pretend reading perfectly parser tables... Nonetheless, all
3413 the other tests pass correctly, the table look OK, even though the
3414 presence of `$axiom' is to be noted: AFAICS it is useless (but
3417 2001-12-29 Akim Demaille <akim@epita.fr>
3419 * src/reader.c (readgram): Don't add the rule 0 if there were no
3420 rules read. In other words, add it _after_ having performed
3421 grammar sanity checks.
3422 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3424 2001-12-29 Akim Demaille <akim@epita.fr>
3426 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3427 visible, and some states have now a different number.
3429 2001-12-29 Akim Demaille <akim@epita.fr>
3431 * src/reader.c (readgram): Bind the initial rule's lineno to that
3433 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3434 (Solved SR Conflicts): Adjust rule 0's line number.
3436 2001-12-29 Akim Demaille <akim@epita.fr>
3438 Fix the `GAWK Grammar' failure.
3440 * src/LR0.c (final_state): Initialize to -1 so that we do compute
3441 the reductions of the first state which was mistakenly confused
3442 with the final state because precisely final_state was initialized
3444 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3445 now noticed by Bison.
3446 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3447 have a reduction on $default.
3449 2001-12-29 Akim Demaille <akim@epita.fr>
3451 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3453 * src/closure.c (print_closure): Likewise.
3454 * src/derives.c (print_derives): Likewise.
3455 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3458 2001-12-29 Akim Demaille <akim@epita.fr>
3460 * src/lalr.c (lookaheads_print): New.
3461 (lalr): Call it when --trace-flag.
3462 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3465 2001-12-29 Akim Demaille <akim@epita.fr>
3467 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3468 when walking through ritem, even via rule->rhs.
3469 * src/reduce.c (dump_grammar, useful_production, reduce_output)
3470 (useful_production, useless_nonterminals): Likewise.
3471 (reduce_grammar_tables): Likewise, plus update nritems.
3472 * src/nullable.c (set_nullable): Likewise.
3473 * src/lalr.c (build_relations): Likewise.
3474 * tests/sets.at (Nullable): Adjust.
3475 Fortunately, now, the $axiom is no longer nullable.
3477 2001-12-29 Akim Demaille <akim@epita.fr>
3479 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3481 * src/gram.c (ritem_longest_rhs): Likewise.
3482 * src/reduce.c (nonterminals_reduce): Likewise.
3483 * src/print_graph.c (print_graph): Likewise.
3484 * src/output.c (output_rule_data): Likewise.
3485 * src/nullable.c (set_nullable): Likewise.
3487 2001-12-29 Akim Demaille <akim@epita.fr>
3489 * src/output.c: Comment changes.
3491 2001-12-27 Paul Eggert <eggert@twinsun.com>
3493 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3494 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3495 Sparc, as they were causing more porting problems than the
3496 (minor) performance improvement was worth.
3498 Also, catch up with 1.31's YYSTD.
3500 2001-12-27 Akim Demaille <akim@epita.fr>
3502 * src/output.c (output_gram): Rely on nritems, not the
3503 0-sentinel. See below.
3504 Use -1 as separator, not 0.
3505 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3506 Rely on -1 as separator in yyrhs, instead of 0.
3507 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3508 twice `Now at end of input', therefore there are two lines less to
3511 2001-12-27 Akim Demaille <akim@epita.fr>
3513 * tests/regression.at (Unresolved SR Conflicts):
3514 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3517 2001-12-27 Akim Demaille <akim@epita.fr>
3519 * src/LR0.c (new_state): Recognize the final state by the fact it
3520 is reached by eoftoken.
3521 (insert_start_shifting_state, insert_eof_shifting_state)
3522 (insert_accepting_state, augment_automaton): Remove, since now
3523 these states are automatically computed from the initial state.
3524 (generate_states): Adjust.
3525 * src/print.c: When reporting a rule number to the user, substract
3526 1, so that the axiom rule is rule 0, and the first user rule is 1.
3527 * src/reduce.c: Likewise.
3528 * src/print_graph.c (print_core): For the time being, just as for
3529 the report, depend upon --trace-flags to dump the full set of
3531 * src/reader.c (readgram): Once the grammar read, insert the rule
3532 0: `$axiom: START-SYMBOL $'.
3533 * tests/set.at: Adjust: rule 0 is now displayed, and since the
3534 number of the states has changed (the final state is no longer
3535 necessarily the last), catch up.
3537 2001-12-27 Akim Demaille <akim@epita.fr>
3539 Try to make the use of the eoftoken valid. Given that its value
3540 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3541 is used instead of > 0 where appropriate, (ii), depend upon nritems
3542 instead of the 0-sentinel.
3544 * src/gram.h, src/gram.c (nritems): New.
3545 Expected to be duplication of nitems, but for the time being...
3546 * src/reader.c (packgram): Assert nritems and nitems are equal.
3547 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3548 * src/closure.c (print_closure, print_fderives): Likewise.
3549 * src/gram.c (ritem_print): Likewise.
3550 * src/print.c (print_core, print_grammar): Likewise.
3551 * src/print_graph.c: Likewise.
3553 2001-12-27 Akim Demaille <akim@epita.fr>
3555 * src/main.c (main): If there are complains after grammar
3556 reductions, then output the report anyway if requested, then die.
3557 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3558 * src/reader.c (eoftoken): New.
3559 (parse_token_decl): If the token being defined has value `0', it
3561 (packsymbols): No longer hack `tags' to insert `$' by hand.
3562 Be sure to preserve the value of the eoftoken.
3563 (reader): Make sure eoftoken is defined.
3564 Initialize nsyms to 0: now eoftoken is created just like the others.
3565 * src/print.c (print_grammar): Don't special case the eof token.
3566 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3567 lie anyway, albeit pleasant.
3568 * tests/calc.at: Exercise error messages with eoftoken.
3569 Change the grammar so that empty input is invalid.
3570 Adjust expectations.
3571 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3573 2001-12-27 Akim Demaille <akim@epita.fr>
3575 * configure.in: Check the protos of strchr ans strspn.
3576 Replace strchr if needed.
3577 * src/system.h: Provide the protos of strchr, strspn and memchr if
3579 * lib/strchr.c: New.
3580 * src/reader.c (symbols_save): Use strchr.
3582 2001-12-27 Akim Demaille <akim@epita.fr>
3584 * src/print.c, src/print_graph.c (escape): New.
3585 Use it to quote the TAGS outputs.
3586 * src/print_graph.c (print_state): Now errors are in red, and
3587 reductions in green.
3588 Prefer high to wide: output the state number on a line of its own.
3590 2001-12-27 Akim Demaille <akim@epita.fr>
3592 * src/state.h, src/state.c (reductions_new): New.
3593 * src/LR0.c (set_state_table): Let all the states have a
3594 `reductions', even if reduced to 0.
3595 (save_reductions): Adjust.

3597 * src/print.c (print_reductions, print_actions): Adjust.
3598 * src/output.c (action_row): Adjust.
3600 2001-12-27 Akim Demaille <akim@epita.fr>
3602 * src/state.h, src/state.c (errs_new, errs_dup): New.
3603 * src/LR0.c (set_state_table): Let all the states have an errs,
3604 even if reduced to 0.
3605 * src/print.c (print_errs, print_reductions): Adjust.
3606 * src/output.c (output_actions, action_row): Adjust.
3607 * src/conflicts.c (resolve_sr_conflict): Adjust.
3609 2001-12-27 Akim Demaille <akim@epita.fr>
3611 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3613 2001-12-27 Akim Demaille <akim@epita.fr>
3615 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3616 * src/print.c: here.
3617 (lookaheadset, shiftset): New, used as additional storage by
3619 (print_results): Adjust.
3620 (print_shifts, print_gotos, print_errs): New, extracted from...
3621 (print_actions): here.
3622 * src/print_graph.c (print_actions): Remove dead code.
3624 2001-12-27 Akim Demaille <akim@epita.fr>
3626 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3629 2001-12-27 Akim Demaille <akim@epita.fr>
3631 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3632 (build_relations): Adjust.
3634 2001-12-27 Akim Demaille <akim@epita.fr>
3636 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3639 2001-12-27 Akim Demaille <akim@epita.fr>
3641 * src/reader.c (packgram): Catch nitems overflows.
3643 2001-12-27 Akim Demaille <akim@epita.fr>
3645 * src/files.c, src/files.h (guard_obstack): Remove.
3646 * src/output.c (output): Adjust.
3647 * src/reader.c (parse_braces): New, factoring...
3648 (copy_action, copy_guard): these two which are renamed as...
3649 (parse_action, parse_guard): these.
3650 As a voluntary consequence, using braces around guards is now
3653 2001-12-27 Akim Demaille <akim@epita.fr>
3655 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3656 * src/reader.c (symbol_list): `guard' and `guard_line' are new
3658 (symbol_list_new): Adjust.
3659 (copy_action): action_line is the first line, not the last.
3660 (copy_guard): Just as for actions, store the `action' only, not
3661 the switch/case/break flesh.
3662 Don't parse the user action that might follow the guard, let...
3663 (readgram): do it, i.e., now, there can be an action after a
3665 In other words the guard is just explicitly optional.
3667 * src/output.c (guards_output): New.
3668 (output_parser): Call it when needed.
3669 (output): Also free the guard and attrs obstacks.
3670 * src/files.c, src/files.h (obstack_save): Remove.
3671 (output_files): Remove.
3672 As a result, if one needs the former `.act' file, using an
3673 appropriate skeleton which requires actions and guards is now
3675 * src/main.c (main): Adjust.
3676 * tests/semantic.at: New.
3677 * tests/regression.at: Use `input.y' as input file name.
3678 Avoid 8+3 problems by requiring input.c when the test needs the

3683 * src/reader.c (symbol_list_new): Be sure to initialize all the
3686 2001-12-27 Akim Demaille <akim@epita.fr>
3688 All the hacks using a final pseudo state are now useless.
3690 * src/LR0.c (set_state_table): state_table holds exactly nstates.
3691 * src/lalr.c (nLA): New.
3692 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3693 instead of lookaheadsp from the pseudo state (nstate + 1).
3695 2001-12-27 Akim Demaille <akim@epita.fr>
3697 * src/output.c (action_row, token_actions): Use a state_t instead
3698 of a integer, and nlookaheads instead of the following state's
3701 2001-12-27 Akim Demaille <akim@epita.fr>
3703 * src/conflicts.c (log_resolution, flush_shift)
3704 (resolve_sr_conflict, set_conflicts, solve_conflicts)
3705 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3706 (conflicts_print, print_reductions): Use a state_t instead of an
3707 integer when referring to a state.
3708 As much as possible, depend upon nlookaheads, instead of the
3709 `lookaheadsp' member of the following state (since lookaheads of
3710 successive states are successive, the difference between state n + 1
3711 and n served as the number of lookaheads for state n).
3712 * src/lalr.c (add_lookback_edge): Likewise.
3713 * src/print.c (print_core, print_actions, print_state)
3714 (print_results): Likewise.

3719 2001-12-27 Akim Demaille <akim@epita.fr>
3721 * src/bison.hairy: Formatting/comment changes.
3723 Remove `register' indications.
3724 Add plenty of `static'.
3726 2001-12-27 Akim Demaille <akim@epita.fr>
3728 * src/output.c (prepare): Drop the muscle `ntbase' which
3730 * src/bison.simple: Formatting/comment changes.
3731 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3732 is an undocumented synonym.
3734 2001-12-22 Akim Demaille <akim@epita.fr>
3736 * src/output.c (output_table_data): Change the prototype to use
3737 `int' for array ranges: some invocations do pass an int, not a
3739 Reported by Wayne Green.
3741 2001-12-22 Akim Demaille <akim@epita.fr>
3743 Some actions of web2c.y are improperly triggered.
3744 Reported by Mike Castle.
3746 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

3748 (Web2c Report): this.
3749 (Web2c Actions): New.
3751 2001-12-22 Akim Demaille <akim@epita.fr>
3753 Reductions in web2c.y are improperly reported.
3754 Reported by Mike Castle.
3756 * src/conflicts.c (print_reductions): Fix.
3757 * tests/regression.at (Web2c): New.
3759 2001-12-18 Akim Demaille <akim@epita.fr>
3761 Some host fail on `assert (!"foo")', which expands to
3762 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3763 Reported by Nelson Beebee.
3765 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3766 `#define it_succeeded 0' and `assert (it_succeeded)'.
3768 2001-12-17 Marc Autret <autret_m@epita.fr>
3770 * src/bison.simple: Don't hard code the skeleton line and filename.
3771 * src/output.c (output_parser): Rename 'line' as 'output_line'.
3772 New line counter 'skeleton_line' (skeleton-line muscle).
3774 2001-12-17 Paul Eggert <eggert@twinsun.com>
3776 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3777 YYDEBUG must be defined to a nonzero value.
3779 * src/bison.simple (yytname): Do not assume that the user defines
3780 YYDEBUG to a properly parenthesized expression.
3782 2001-12-17 Akim Demaille <akim@epita.fr>
3784 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3785 nlookaheads is a new member.
3787 * src/lalr.h (nlookaheads): Remove this orphan declaration.
3788 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
3791 2001-12-17 Akim Demaille <akim@epita.fr>

3794 * src/main.c (main): Don't open/close files, nor invoke lex_free,
3796 * src/reader.c (reader): Do it.
3798 2001-12-17 Akim Demaille <akim@epita.fr>
3800 * src/conflicts.c (print_reductions): Formatting changes.
3802 2001-12-17 Akim Demaille <akim@epita.fr>
3804 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
3805 (flush_reduce): New.
3806 (resolve_sr_conflict): Adjust.
3808 2001-12-17 Akim Demaille <akim@epita.fr>
3810 * src/output.c (output_obstack): Be static and rename as...
3811 (format_obstack): this, to avoid any confusion with files.c's
3813 * src/reader.h (muscle_obstack): Move to...
3814 * src/output.h: here, since it's defined in output.c.
3816 2001-12-17 Akim Demaille <akim@epita.fr>
3818 * src/output.c (action_row, save_column, default_goto)
3819 (sort_actions, matching_state, pack_vector): Better variable
3822 2001-12-17 Akim Demaille <akim@epita.fr>
3824 * src/output.c: Various formatting changes.
3826 2001-12-17 Akim Demaille <akim@epita.fr>
3828 * src/files.c (output_files): Free the output_obstack.
3829 * src/main.c (main): Call print and print_graph conditionally.
3830 * src/print.c (print): Work unconditionally.
3831 * src/print_graph.c (print_graph): Work unconditionally.
3832 * src/conflicts.c (log_resolution): Output only if verbose_flag.
3834 2001-12-16 Marc Autret <autret_m@epita.fr>
3836 * src/output.c (actions_output): Fix. When we use %no-lines,
3837 there is one less line per action.
3839 2001-12-16 Marc Autret <autret_m@epita.fr>
3841 * src/bison.simple: Remove a useless #line directive.
3842 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3843 * src/output.c (get_lines_number): New.
3844 (output_parser): Adjust, now takes care about the lines of a
3847 (actions_output): Computes the number of lines taken by actions.
3848 (output_master_parser): Insert new skeleton which is the name of
3849 the output parser file name.
3851 2001-12-15 Marc Autret <autret_m@epita.fr>
3853 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
3855 2001-12-15 Marc Autret <autret_m@epita.fr>
3857 * src/output.c (output_gram): Keep track of the hairy one.
3859 2001-12-15 Akim Demaille <akim@epita.fr>
3861 Make `make distcheck' work.
3863 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3864 system.h which uses libgettext.h.
3866 2001-12-15 Akim Demaille <akim@epita.fr>
3868 * src/nullable.c (set_nullable): Useless rules must be skipped,
3869 otherwise, since we range over their symbols, we might look at a
3870 nonterminal which no longer ``exists'', i.e., it is not counted in
3871 `nvars', hence we overflow our arrays.
3873 2001-12-15 Akim Demaille <akim@epita.fr>
3875 The header can also be produced directly, without any obstack!
3878 * src/files.c, src/files.h (defines_obstack): Remove.
3879 (compute_header_macro): Global.
3880 (defines_obstack_save): Remove.
3881 * src/reader.c (parse_union_decl): No longer output to
3882 defines_obstack: its content can be found in the `stype' muscle
3884 (output_token_translations): Merge into...
3885 (symbols_output): this.
3887 (symbols_save): this.
3889 * src/output.c (header_output): New.
3892 2001-12-15 Akim Demaille <akim@epita.fr>
3894 * src/reader.c (parse_union_decl): Instead of handling two obstack
3895 simultaneously, use one to define the `stype' muscle, and use the
3896 value of the latter to fill defines_obstack.
3897 (copy_comment): Remove.
3898 (copy_comment2): Work for a single obstack.
3900 (copy_comment): this.
3902 2001-12-15 Akim Demaille <akim@epita.fr>
3904 * src/lex.c, src/lex.h (xgetc): No longer static.
3905 * src/reader.c (parse_union_decl): Revamp.
3907 2001-12-15 Akim Demaille <akim@epita.fr>
3909 Still making progress in separating Bison into (i) input, (ii)
3910 process, (iii) output: now we can directly output the parser file
3911 without using table_obstack at all.
3913 * src/files.c, src/files.h (table_obstack): Bye bye.
3914 (parser_file_name): New.
3915 * src/files.c (compute_output_file_names): Compute it.
3916 * src/output.c (actions_output, output_parser)
3917 (output_master_parser): To a file instead of an obstack.
3919 2001-12-15 Akim Demaille <akim@epita.fr>
3921 Attach actions to rules, instead of pre-outputting them to
3924 * src/gram.h (rule_t): action and action_line are new members.
3925 * src/reader.c (symbol_list): Likewise.
3926 (copy_action): Save the actions within the rule.
3927 (packgram): Save them in rule_table.
3928 * src/output.c (actions_output): New.
3929 (output_parser): Use it on `%%actions'.
3930 (output_rule_data): Don't free rule_table.
3932 (prepare): Don't save the `action' muscle.
3933 * src/bison.simple: s/%%action/%%actions/.
3935 2001-12-15 Akim Demaille <akim@epita.fr>
3937 * src/reader.c (copy_action): When --yacc, don't append a `;'
3938 to the user action: let it fail if lacking.
3939 Suggested by Arnold Robbins and Tom Tromey.
3941 2001-12-14 Akim Demaille <akim@epita.fr>
3943 * src/lex.c (literalchar): Simply return the char you decoded, non
3944 longer mess around with obstacks and int pointers.
3947 2001-12-14 Akim Demaille <akim@epita.fr>
3949 * src/lex.c (literalchar): Don't escape the special characters,
3950 just decode them, and keep them as char (before, eol was output as
3951 the 2 char string `\n' etc.).
3952 * src/output.c (output_rule_data): Use quotearg to output the
3955 2001-12-13 Paul Eggert <eggert@twinsun.com>
3957 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3958 Do not infringe on the global user namespace when using C++.
3959 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3960 All uses of `fprintf' and `stderr' changed.
3962 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3964 2001-12-13 Akim Demaille <akim@epita.fr>
3966 The computation of nullable is broken: it doesn't handle empty
3969 * tests/torture.at (GNU AWK Grammar): New.
3970 * tests/sets.at (Nullable): New.
3971 * src/nullable.c (set_nullable): Instead of blindly looping over
3972 `ritems', loop over the rules, and then over their rhs's.
3974 Work around Autotest bugs.
3976 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3977 frame, because Autotest understand lines starting with a `+' as
3978 traces from the shell. Then, they are not processed properly.
3979 Admittedly an Autotest bug, but we don't have time to wait for
3980 Autotest to catch up.
3981 * tests/regression.at (Broken Closure): Adjust to the new table
3984 * tests/sets.at: here.
3986 2001-12-13 Akim Demaille <akim@epita.fr>
3988 * src/closure.c (closure): Use nrules instead of playing tricks
3991 2001-12-13 Akim Demaille <akim@epita.fr>
3993 * src/print.c (print_actions): Output the handling of `$' as the
3994 traces do: shifting the token EOF. Before EOF was treated as a
3996 * tests/regression.at: Adjust some tests.
3997 * src/print_graph.c (print_core): Complete the set of items via
3998 closure. The next-to-final and final states are still unsatisfying,
3999 but that's to be addressed elsewhere.
4000 No longer output the rule numbers, but do output the state number.
4001 A single loop for the shifts + gotos is enough, but picked a
4002 distinct color for each.
4003 (print_graph): Initialize and finalize closure.
4005 2001-12-13 Akim Demaille <akim@epita.fr>
4007 * src/reader.c (readgram): Remove dead code, an strip useless
4009 (get_type): Remove, unused.
4011 2001-12-12 Akim Demaille <akim@epita.fr>
4013 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4014 on that of lib/error.c.
4016 2001-12-12 Akim Demaille <akim@epita.fr>
4018 Some hosts don't like `/' in includes.
4020 * src/system.h: Include libgettext.h without qualifying the path.
4021 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4024 2001-12-11 Marc Autret <autret_m@epita.fr>
4026 * src/output.c (output_parser): Remove useless muscle.
4028 2001-12-11 Marc Autret <autret_m@epita.fr>
4030 * src/bison.simple: Remove #line just before %%epilogue. It
4031 is now handled in ...
4032 * src/reader.c (read_additionnal_code): Add the output of a
4033 #line for the epilogue.
4035 2001-12-10 Marc Autret <autret_m@epita.fr>
4037 * src/reader.c (copy_definition): Re-use CPP-outed code which
4038 replace precedent remove.
4039 * src/bison.simple: Remove #line before %%prologue because
4040 %%input-line is wrong at this time.
4042 2001-12-10 Marc Autret <autret_m@epita.fr>
4044 * src/reader.c (symbols_output): Clean up.
4045 * src/output.c (output_gram, output): Clean up.
4047 2001-12-10 Akim Demaille <akim@epita.fr>
4049 * src/lalr.c (initialize_lookaheads): New. Extracted from...
4050 * src/LR0.c (set_state_table): here.
4051 * src/lalr.c (lalr): Call it.
4053 2001-12-10 Akim Demaille <akim@epita.fr>
4055 * src/state.h (shifts): Remove the `number' member: shifts are
4056 attached to state, hence no longer need to be labelled with a
4059 2001-12-10 Akim Demaille <akim@epita.fr>
4061 Now that states have a complete set of members, the linked list of
4062 shifts is useless: just fill directly the state's shifts member.
4064 * src/state.h (shifts): Remove the `next' member.
4065 * src/LR0.c (first_state, last_state): Remove.
4067 (augment_automaton): Don't look for the shifts that must be added
4068 a shift on EOF: it is those of the state we looked for! But now,
4069 since shifts are attached, it is no longer needed to looking
4070 merely by its id: its number.
4072 2001-12-10 Akim Demaille <akim@epita.fr>
4074 * src/LR0.c (augment_automaton): Better variable locality.
4075 Remove an impossible branch: if there is a state corresponding to
4076 the start symbol being shifted, then there is shift for the start
4077 symbol from the initial state.
4079 2001-12-10 Akim Demaille <akim@epita.fr>
4081 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4082 only when appropriate: when insert_start_shifting_state' is not
4084 * tests/regression.at (Rule Line Numbers): Adjust.
4086 2001-12-10 Akim Demaille <akim@epita.fr>
4088 * src/LR0.c (augment_automaton): Now that all states have shifts,
4089 merge the two cases addition shifts to the initial state.
4091 2001-12-10 Akim Demaille <akim@epita.fr>
4093 * src/lalr.c (set_state_table): Move to...
4095 * src/lalr.c (lalr): Don't call it...
4096 * src/LR0.c (generate_states): do it.
4097 * src/LR0.h (first_state): Remove, only the table is used.
4099 2001-12-10 Akim Demaille <akim@epita.fr>
4101 * src/LR0.h (first_shift, first_reduction): Remove.
4102 * src/lalr.c: Don't use first_shift: find shifts through the
4105 2001-12-10 Akim Demaille <akim@epita.fr>
4107 * src/LR0.c: Attach shifts to states as soon as they are
4109 * src/lalr.c (set_state_table): Instead of assigning shifts to
4110 state, just assert that the mapping was properly done.
4112 2001-12-10 Akim Demaille <akim@epita.fr>
4114 * src/LR0.c (insert_start_shift): Rename as...
4115 (insert_start_shifting_state): this.
4116 (insert_eof_shifting_state, insert_accepting_state): New.
4117 (augment_automaton): Adjust.
4118 Better locality of the variables.
4119 When looking if the start_symbol is shifted from the initial
4120 state, using `while (... symbol != start_symbol ...)' sounds
4121 better than `while (... symbol < start_symbol ...)': If fail
4122 to see how the order between symbols could be relevant!
4124 2001-12-10 Akim Demaille <akim@epita.fr>
4126 * src/getargs.h: Don't declare `spec_name_prefix' and
4127 `spec_file_prefix', declared by src/files.h.
4128 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4129 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4130 * src/output.c (prepare): Adjust.
4131 * src/reader.c (symbols_output): Likewise.
4132 * src/vmsgetargs.c: Vaguely adjust, but who cares?
4134 2001-12-10 Akim Demaille <akim@epita.fr>
4136 * src/muscle_tab.c (muscle_init): NULL is a better default than
4139 2001-12-10 Akim Demaille <akim@epita.fr>
4141 * src/reader.c (reader): Calling symbols_output once is enough.
4143 2001-12-10 Akim Demaille <akim@epita.fr>
4145 Now that states have a complete set of members, the linked list of
4146 reductions is useless: just fill directly the state's reductions
4149 * src/state.h (struct reductions): Remove member `number' and
4151 * src/LR0.c (first_reduction, last_reduction): Remove.
4152 (save_reductions): Don't link the new reductions, store them in
4154 * src/lalr.c (set_state_table): No need to attach reductions to
4155 states, it's already done.
4156 * src/output.c (output_actions): No longer free the shifts, then
4157 the reductions, then the states: free all the states and their
4160 2001-12-10 Akim Demaille <akim@epita.fr>
4162 * src/options.c (OPTN, DRTV, BOTH): New.
4163 (option_table): Use them.
4165 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's

4167 * src/options.c: Don't include stdio.h and xalloc.h for the same
4170 2001-12-10 Akim Demaille <akim@epita.fr>
4172 * src/output.c (output, prepare): Make sure the values of the

4192 * tests/Makefile.am: Adjust.
4194 2001-12-10 Akim Demaille <akim@epita.fr>
4196 One structure for states is enough, even though theoretically
4197 there are LR(0) states and LALR(1) states.
4199 * src/lalr.h (state_t): Remove.
4200 (state_table): Be state_t **, not state_t *.
4201 * src/state.h (core, CORE_ALLOC): Rename as...
4202 (state_t, STATE_ALLOC): this.
4203 Add the LALR(1) members: shifts, reductions, errs.
4204 * src/LR0.c (state_table): Rename as...
4205 (state_hash): this, to avoid name clashes with the global
4207 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c

4212 Bison dumps core on bash.y.
4213 Reported by Pascal Bart.
4215 * src/warshall.c (bitmatrix_print): New.
4217 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),

4221 2001-12-05 Akim Demaille <akim@epita.fr>
4223 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and

4237 * src/reduce.c (reduce_grammar_tables): No longer disable the
4238 removal of useless rules via CPP but via `if (0)', so that the
4239 compiler still check the code is valid.
4240 For instance, it should have noticed `rline' no longer exists: use
4241 the `line' member of rule_t.
4242 * src/gram.c (dummy, rline): Remove, unused.
4244 2001-12-05 Akim Demaille <akim@epita.fr>

4247 * src/main.c (berror): Remove, unused.
4249 2001-12-05 Akim Demaille <akim@epita.fr>
4251 New experimental feature: if --verbose --trace output all the
4252 items of a state, not only its kernel.
4254 * src/print.c (print_core): If `trace_flag', then invoke closure
4255 before outputting the items of the state (print_core is no longer
4256 a correct name them).

4273 indexed by nonterminals.
4275 2001-12-05 Akim Demaille <akim@epita.fr>
4277 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

4297 locality, BITISSET, RESETBIT etc.
4299 2001-12-05 Akim Demaille <akim@epita.fr>
4301 Pessimize the code to simplify it: from now on, all the states
4302 have a valid SHIFTS, which NSHIFTS is possibly 0.
4304 * src/LR0.c (shifts_new): Be global and move to..
4305 * src/state.c, src/state.h: here.
4306 * src/conflicts, src/lalr.c, src/output.c, src/print.c,

4370 2001-12-05 Akim Demaille <akim@epita.fr>
4372 * src/lalr.c (maxrhs): Move to...
4373 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4374 * src/lalr.c (build_relations): Adjust.
4376 2001-12-05 Akim Demaille <akim@epita.fr>
4378 * src/lalr.c (transpose): Free the memory allocated to the
4379 argument, as it is replaced by the results by the unique caller.
4380 (build_relations): Merely invoke transpose: it handles the memory
4382 Improve variable locality.
4383 Avoid variables used as mere abbreviations.
4384 (compute_lookaheads): Use arrays instead of pointers.
4386 2001-12-05 Akim Demaille <akim@epita.fr>

4402 2001-12-05 Akim Demaille <akim@epita.fr>
4404 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4405 the handling of squeue.
4406 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4408 2001-12-05 Akim Demaille <akim@epita.fr>
4410 Because useless nonterminals are now kept alive (instead of being
4411 `destroyed'), we now sometimes examine them, and store information
4412 related to them. Hence we need to know their number, and adjust
4415 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4417 * src/LR0.c (allocate_itemsets): The memory allocated to
4418 `symbol_count' was used for two different purpose: once to count
4419 the number of occurrences of each symbol, and later reassigned to
4420 `shift_symbol', containing the symbol that can be shifted from a
4422 Deobfuscate, i.e., allocate, use and free `symbol_count' here
4424 (new_itemsets): Allocate `shift_symbol' here.
4425 (allocate_itemsets): symbol_count includes useless nonterminals.
4427 (free_storage): Use `free', not `XFREE', for pointers that cannot
4430 2001-12-05 Akim Demaille <akim@epita.fr>
4432 * src/nullable.c (set_nullable): Deobfuscate the handling of
4434 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4436 2001-12-05 Akim Demaille <akim@epita.fr>
4438 * src/gram.c, src/gram.h (ritem_print): New.
4439 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4440 (This useless function was defined only to work around VMS linkers
4441 that can't handle compilation units with variables only).
4442 * src/reduce.c (dump_grammar): Use it to trace the construction of
4445 2001-12-04 Paul Eggert <eggert@twinsun.com>
4447 * src/bison.simple (union yyalloc): Change member names
4448 to be the same as the stack names.
4449 (yyparse): yyptr is now union yyalloc *, not char *.
4450 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
4451 and may generate better code on some machines.
4452 (yystpcpy): Use prototype if __STDC__ is defined, not just
4453 if __cplusplus is defined.
4455 2001-11-30 Akim Demaille <akim@epita.fr>
4457 * configure.in (WARNING_CFLAGS): Add -Werror when possible.

4461 Include WARNING_CFLAGS here.
4462 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

4470 (SIZE_MAX, UINT_MAX): New macros.
4471 (quotearg_n_options): Abort if N is negative.
4472 Avoid overflow check on hosts where size_t is 64 bits and int
4473 is 32 bits, as overflow is impossible there.
4474 Fix off-by-one typo that caused unnecessary reallocation.
4476 2001-11-29 Paul Eggert <eggert@twinsun.com>
4478 Name space cleanup in generated parser.
4480 * doc/bison.texinfo (Bison Parser): Discuss system headers
4481 and their effect on the user name space.
4484 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

4491 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4492 Simplify test for whather <alloca.h> exists.
4494 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4496 (<stdio.h>): Include if YYDEBUG.
4498 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
4499 ! defined (yyoverflow) && ! defined (yymemcpy).
4501 (yymemcpy, yyparse): Rename local variables as needed so that
4502 they all begin with 'yy'.
4504 (yystrlen, yystpcpy): New functions.
4506 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4509 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
4510 instead of relying on string.h functions. Use YYSTACK_ALLOC
4511 and YYSTACK_FREE instead of malloc and free.
4513 2001-11-30 Akim Demaille <akim@epita.fr>
4515 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4516 before their first uses.

4523 2001-11-30 Akim Demaille <akim@epita.fr>
4525 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4526 if body instead of `;' to pacify GCC's warnings.
4528 2001-11-30 Akim Demaille <akim@epita.fr>
4530 Instead of mapping the LHS of unused rules to -1, keep the LHS
4531 valid, but flag the rules as invalid.
4533 * src/gram.h (rule_t): `useful' is a new member.
4534 * src/print.c (print_grammar): Adjust.
4535 * src/derives.c (set_derives): Likewise.
4536 * src/reader.c (packgram, reduce_output): Likewise.

4547 2001-11-30 Akim Demaille <akim@epita.fr>
4549 * src/reduce.c (nonterminals_reduce): Instead of throwing away
4550 useless nonterminals, move them at the end of the symbol arrays.
4551 (reduce_output): Adjust.

4565 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4567 (union yyalloc): New type.
4568 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4569 an arbitrary restriction on hosts where size_t is wider than int.
4571 (yyparse): Don't dump core if alloca or malloc fails; instead, report
4572 a parser stack overflow. Allocate just one block of memory for all
4573 three stacks, instead of allocating three blocks; this typically is
4574 faster and reduces fragmentation.
4576 Do not limit the number of items in the stack to a value that fits
4577 in 'int', as this is an arbitrary limit on hosts with 64-bit
4578 size_t and 32-bit int.
4580 2001-11-29 Marc Autret <autret_m@epita.fr>
4582 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4583 of defining YYERROR_VERBOSE.

4633 2001-11-28 Akim Demaille <akim@epita.fr>
4635 * src/closure.c (closure): Instead of looping over word in array
4636 then bits in words, loop over bits in array.
4638 2001-11-28 Akim Demaille <akim@epita.fr>
4640 * src/closure.c (closure): No longer optimize the special case
4641 where all the bits of `ruleset[r]' are set to 0, to make the code
4644 2001-11-28 Akim Demaille <akim@epita.fr>
4646 * src/closure.c (closure): `r' and `c' are new variables, used to
4647 de-obfuscate accesses to RULESET and CORE.

4660 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
4661 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
4662 as all tags are free'ed afterwards.
4665 2001-11-27 Paul Eggert <eggert@twinsun.com>
4667 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
4668 use alloca when we didn't want to, and vice versa.
4670 2001-11-27 Marc Autret <autret_m@epita.fr>
4672 * src/muscle_tab.c (muscle_init): Remove 'verbose' muscle

6381 2001-02-08 Akim Demaille <akim@epita.fr>
6383 * src/conflicts.c (conflict_report): Be sure not to append to res
6384 between two calls, which could happen if both first sprintf were
6385 skipped, but not the first cp += strlen.
6387 2001-02-08 Akim Demaille <akim@epita.fr>
6389 * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
6390 New, from fileutils 4.0.37.
6391 * configure.in: Require Autoconf 2.49c. I took some time before
6392 making this decision. This is the only way out for portability
6393 issues in Bison, it would mean way too much duplicate effort to
6394 import in Bison features implemented in 2.49c since 2.13.
6395 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
6397 2001-02-02 Akim Demaille <akim@epita.fr>

6402 2001-01-19 Akim Demaille <akim@epita.fr>
6404 Get rid of the ad hoc handling of token_buffer in the scanner: use
6407 * src/lex.c (token_obstack): New.
6408 (init_lex): Initialize it. No longer call...

6414 * src/lex.h: Rename all the tokens:
6415 s/\bENDFILE\b/tok_eof/g;
6416 s/\bIDENTIFIER\b/tok_identifier/g;
6418 Let them be enums, not #define, to ease debugging.

6431 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
6433 Handle the actions for `%semantic_parser' and `%pure_parser' here,
6434 instead of returning a token.
6435 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
6436 * src/reader.c (read_declarations): Adjust.
6437 * src/files.c (open_files): Don't call `compute_base_names', don't
6438 compute `attrsfile' since they depend upon data which might be
6439 *in* the input file now.
6440 (output_files): Do it here.
6441 * src/output.c (output_headers): Document the fact that this patch
6442 introduces a guaranteed SEGV for semantic parsers.
6443 * doc/bison.texinfo: Document them.
6444 * tests/suite.at: Exercise these %options.
6446 2000-12-20 Akim Demaille <akim@epita.fr>

6471 * src/files.c (open_files): Actually the `.output' file is based
6472 on the short_base_name, not base_name.
6473 * tests/suite.at (Checking output file names): Adjust.
6475 2000-12-20 Akim Demaille <akim@epita.fr>

6500 * src/files.c (strsuffix): New.
6501 (stringappend): Be just like strcat but allocate.

6517 2000-12-19 Akim Demaille <akim@epita.fr>
6519 * src/output.c (output_parser): Compute the `#line' lines when
6521 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
6522 Suggested by Hans Aberg.
6524 2000-12-19 Akim Demaille <akim@epita.fr>

6544 2000-12-19 Akim Demaille <akim@epita.fr>
6546 * src/files.c (open_files): Yipee! We no longer need all the code
6547 looking for `/tmp' since we have no tmp file.
6549 2000-12-19 Akim Demaille <akim@epita.fr>
6551 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

6578 * lib/obstack.h: Formatting changes.
6579 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6580 prevents type checking.
6581 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6582 cast the value to (void *): assigning a `foo *' to a `void *'

6585 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6593 * tests/atgeneral.m4: Update from CVS Autoconf.
6595 2000-11-17 Akim Demaille <akim@epita.fr>
6597 * tests/regression.m4 (%union and --defines): New test,
6598 demonstrating a current bug in the obstack implementation.
6600 2000-11-17 Akim Demaille <akim@epita.fr>
6602 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

6629 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
6630 argument `data' for consistency with the prototypes.
6632 (obstack_copy, obstack_copy0): Rename the second argument as
6633 `address' for consistency. Qualify it `const'.
6634 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
6635 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
6636 `const' their input argument (`data' or `address').
6637 Adjust the corresponding macros to include `const' in casts.
6639 2000-11-03 Akim Demaille <akim@epita.fr>
6641 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.
6642 s/PFILE1/BISON_HAIRY/.

6647 For some reason, this was not applied.
6649 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
6650 `unlink': it's no longer used.
6652 2000-11-03 Akim Demaille <akim@epita.fr>
6654 * src/files.c (skeleton_find): New function, eved out of...

6657 2000-11-03 Akim Demaille <akim@epita.fr>
6661 * src/files.c (obstack_save): New function.
6662 (done): Rename as...
6663 (output_files): this.
6665 * src/main.c (main): Don't use `atexit' to register `done', since
6666 it no longer has to remove tmp files, just call `output_files'
6667 when there are no errors.
6669 2000-11-02 Akim Demaille <akim@epita.fr>
6671 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
6672 `unlink': it's no longer used.
6673 * src/files.h: Formatting changes.
6675 2000-11-02 Akim Demaille <akim@epita.fr>

6736 2000-10-16 Akim Demaille <akim@epita.fr>
6738 * src/reader.c (copy_comment2): Expect the input stream to be on
6739 the `/' which is suspected to open a comment, instead of being
6740 called after `//' or `/*' was read.
6741 (copy_comment, copy_definition, parse_union_decl, copy_action)
6742 (copy_guard): Adjust.
6744 2000-10-16 Akim Demaille <akim@epita.fr>
6746 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

6751 * src/reader.c (copy_dollar): New function.
6752 (copy_guard, copy_action): Use it.
6754 2000-10-16 Akim Demaille <akim@epita.fr>
6756 * lib/quote.h, lib/quote.c, lib/quotearg.h, lib/quotearg.c:
6757 * m4/prereq.m4, m4/c-bs-a.m4, m4/mbstate.m4:

6766 2000-10-04 Akim Demaille <akim@epita.fr>
6768 * doc/bison.texinfo: Various typos spotted by Neil Booth.
6770 2000-10-04 Akim Demaille <akim@epita.fr>
6772 When a literal string is used to define two different tokens,
6773 `bison -v' segfaults.
6774 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6776 * tests/regression.m4: New file.
6777 Include the core of the sample provided by Piotr Gackiewicz.
6778 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
6781 2000-10-04 Akim Demaille <akim@epita.fr>
6783 * src/reader.c (parse_expect_decl): Keep `count' within the size
6787 2000-10-02 Paul Eggert <eggert@twinsun.com>

6793 2000-10-02 Akim Demaille <akim@epita.fr>
6795 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
6798 2000-10-02 Akim Demaille <akim@epita.fr>

6801 translation, move some `\n' out of the translated strings.
6803 2000-10-02 Akim Demaille <akim@epita.fr>
6805 The location tracking mechanism is precious for parse error
6806 messages. Nevertheless, it is enabled only when `@n' is used in
6807 the grammar, which is a different issue (you can use it in error
6808 message, but not in the grammar per se). Therefore, there should
6809 be another means to enable it.
6811 * src/getargs.c (getargs): Support `--locations'.
6813 * src/getargs.h (locationsflag): Export it.
6814 * src/lex.c (percent_table): Support `%locations'.
6815 * src/reader.c (yylsp_needed): Remove this variable, now replaced
6816 with `locationsflag'.
6817 * doc/bison.texinfo: Document `--locations' and `%locations'.
6819 * tests/calc.m4: Test it.
6821 For regularity of the names, replace each
6822 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6823 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6824 In addition replace each `flag' with `_flag'.
6826 2000-10-02 Akim Demaille <akim@epita.fr>
6828 Also test parse error messages, including with YYERROR_VERBOSE.
6830 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6832 Use it to check the computations.
6833 Use it to check `nonassoc' is honored.
6834 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6835 `--yyerror-verbose'.
6836 (_AT_CHECK_CALC): Adjust to this option.
6837 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6839 2000-10-02 Akim Demaille <akim@epita.fr>
6841 Test also `--verbose', `--defines' and `--name-prefix'. Testing
6842 the latter demonstrates a flaw in the handling of non debugging
6843 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6844 was used in order to simplify:
6860 unfortunately this leads to a CPP conflict when
6861 `--name-prefix=foo' is used since it produces `#define yydebug
6864 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6865 (YYDPRINTF): New macro.
6867 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6869 Also test `--verbose', `--defines' and `--name-prefix'.

6873 Improve the readability of the produced parsers.
6875 * src/bison.s1: Formatting changes.
6876 Improve the comment related to the `$' mark.
6877 (yydefault): Don't fall through to `yyresume': `goto' there.
6878 * src/output.c (output_parser): When the `$' is met, skip the end
6880 New variable, `number_of_dollar_signs', to check there's exactly
6881 one `$' in the parser skeleton.
6883 2000-10-02 Akim Demaille <akim@epita.fr>
6885 * lib/xstrdup.c: New file, from the fileutils.
6886 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6887 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6888 instead of strlen + xmalloc + strcpy.

6893 * src/gram.h (associativity): New enum type which replaces the
6894 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6895 `right_assoc', `left_assoc' and `non_assoc'.
6896 Adjust all dependencies.

6910 2000-10-02 Akim Demaille <akim@epita.fr>
6912 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6913 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6914 difficult and introduced a lot of core dump. It turns out that
6915 Bison used an implementation of `xmalloc' based on `calloc', and
6916 at various places it does depend upon the initialization to 0. I
6917 have not tried to isolate the pertinent places, and all the former
6918 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6919 someone should address this issue.

7022 `user_toknums' is output as a `short[]' in `output.c', while it is
7023 defined as a `int[]' in `reader.c'. For consistency with the

7068 * src/system.h: Define PARAMS.

7293 or, if the rhs is empty, YYLLOC).
7295 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7297 (yyparse): When providing a default semantic action, provide a
7298 default location action.
7299 (after the $): No longer change `*YYLSP', just stack YYLOC the
7300 same way you stack YYVAL.
7301 * src/reader.c (read_declarations): Use warns.

7328 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7329 One `#if YYDEBUG' remains, since it uses variables which are

7334 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

8056 way to specify the flags -n, -l, and -r. Also added hooks for
8057 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
8058 major changes to files.c.
