355 (handle_action_dollar, handle_action_at): Don't use isdigit,
356 as it mishandles negative chars and it may not work as expected
357 outside the C locale.

599 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
600 for the time being: %locations ought to provide it to yyerror.
602 2002-07-25 Akim Demaille <akim@epita.fr>
604 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

2871 2002-02-14 Paul Eggert <eggert@twinsun.com>
2873 Remove the support for C++ namespace cleanliness; it was

2971 (output_skeleton): Don't look for the skeleton location, let m4 do
2973 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
2975 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2976 (prepare): Given that for the time being changesyntax is not
2977 usable in M4, rename the muscles using `-' to `_'.

2979 * src/output.h (actions_output, guards_output)
2980 (token_definitions_output): Adjust prototypes.

3009 * src/bison.simple (YYSIZE_T): Do not define merely because
3010 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.

3015 Fix `%nonassoc and eof'.
3017 * src/state.c (errs_dup): Aaaah! The failure was due to bytes

3079 * src/system.h: Need to define __attribute__ away for non-GCC
3080 compilers as well (i.e. the vendor C compiler).
3081 Suggested by Albert Chin-A-Young.
3083 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
3085 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
3086 canonical definition.
3087 * src/system.h: Use the canonical definition for PARAMS (avoids
3088 a conflict with the macro from lib/hash.h).

3099 (compute_base_names): Compute the former, drop the latter.
3100 * src/output.c (prepare): Insert the muscles `output-infix', and
3102 * src/parse-skel.y (string, string.1): New.
3103 (section.header): Use it.
3104 (section.yacc): Remove.
3105 (prefix): Remove too.
3106 * src/scan-skel.l: Adjust.
3107 * src/bison.simple, src/bison.hairy: Adjust.
3109 2002-01-09 Akim Demaille <akim@epita.fr>
3111 * configure.in (WERROR_CFLAGS): Compute it.
3112 * src/Makefile.am (CFLAGS): Pass it.
3113 * tests/atlocal.in (CFLAGS): Idem.
3114 * src/files.c: Fix a few warnings.
3115 (get_extension_index): Remove, unused.
3117 2002-01-08 Akim Demaille <akim@epita.fr>
3119 * src/getargs.c (AS_FILE_NAME): New.
3120 (getargs): Use it to convert DOSish file names.
3121 * src/files.c (base_name): Rename as full_base_name to avoid
3122 clashes with `base_name ()'.
3123 (filename_split): New.
3124 (compute_base_names): N-th rewrite, using filename_split.
3126 2002-01-08 Akim Demaille <akim@epita.fr>
3128 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3129 New, stolen from the Fileutils 4.1.
3130 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3131 * configure.in: Check for the presence of memrchr, and of its
3134 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
3136 * lib/hash.h (__P): Added definition for this macro.
3137 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3138 BUILT_SOURCES, to ensure they are generated first.
3139 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3140 %error-verbose to allow bootstrapping with bison 1.30x.
3142 2002-01-06 Akim Demaille <akim@epita.fr>
3144 * src/reader.c (parse_braces): Don't fetch the next char, the
3145 convention is to fetch on entry.
3146 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3147 'switch' without a following semicolon.
3148 * tests/regression.at (braces parsing): New.
3150 2002-01-06 Akim Demaille <akim@epita.fr>
3152 Bison is dead wrong in its RR conflict reports.
3154 * tests/torture.at (GNU Cim Grammar): New.
3155 * src/conflicts.c (count_rr_conflicts): Fix.
3157 2002-01-06 Akim Demaille <akim@epita.fr>
3159 Creating package.m4 from configure.ac causes too many problems.
3161 * tests/Makefile.am (package.m4): Create it by hand,
3162 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3164 2002-01-06 Akim Demaille <akim@epita.fr>
3166 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3169 2002-01-04 Paul Eggert <eggert@twinsun.com>
3171 * doc/bison.texinfo (Debugging):
3172 Remove YYSTDERR; it's no longer defined or used.
3173 Also, s/cstdio.h/cstdio/.
3175 2002-01-03 Akim Demaille <akim@epita.fr>
3177 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3179 2002-01-03 Akim Demaille <akim@epita.fr>
3181 * src/parse-skel.y (process_skeleton): Don't bind the parser's
3182 tracing code to --trace, wait for a better --trace option, with
3185 2002-01-03 Akim Demaille <akim@epita.fr>
3187 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3188 The ISO C++ standard is extremely clear about it: stderr is
3189 considered a macro, not a regular symbol (see table 94 `Header
3190 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3191 Therefore std:: does not apply to it. It still does with fprintf.
3192 Also, s/cstdio.h/cstdio/.
3194 2002-01-03 Akim Demaille <akim@epita.fr>
3196 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3197 for non system headers.
3199 2002-01-02 Akim Demaille <akim@epita.fr>
3201 Equip the skeleton chain with location tracking, runtime trace,
3202 pure parser and scanner.
3204 * src/parse-skel.y: Request a pure parser, locations, and prefix
3206 (%union): Having several members with the same type does not help
3207 type mismatches, simplify.
3208 (YYPRINT, yyprint): New.
3209 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3212 * src/scan-skel.l: Adjust to these changes.
3213 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3214 (LOCATION_PRINT, skel_control_t): New.
3216 2001-12-30 Akim Demaille <akim@epita.fr>
3218 * src/parse-skel.y: Get rid of the shift/reduce conflict:
3219 replace `gb' with BLANKS.
3220 * src/scan-skel.l: Adjust.
3222 2001-12-30 Akim Demaille <akim@epita.fr>
3224 * src/system.h: We don't need nor want bcopy.
3225 Throw away MS-DOS crap: we don't need getpid.
3226 * configure.in: We don't need strndup. It was even causing
3227 problems: because Flex includes the headers *before* us,
3228 _GNU_SOURCE is not defined by config.h, and therefore strndup was
3230 * lib/xstrndup.c: New.
3231 * src/scan-skel.l: Use it.
3232 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3233 * src/parse-skel.y: Use %directives instead of #defines.
3235 2001-12-30 Akim Demaille <akim@epita.fr>
3237 * src/skeleton.h: New.
3238 * src/output.c (output_parser, output_master_parser): Remove, dead
3240 * src/output.h (get_lines_number, actions_output, guards_output)
3241 (token_definitions_output): Prototype them.
3242 * src/parse-skel.y: Add the license notice.
3243 Include output.h and skeleton.h.
3244 (process_skeleton): Returns void, and takes a single parameter.
3245 * src/scan-skel.l: Add the license notice.
3247 Don't use %option yylineno: it seems that then Flex imagines
3248 REJECT has been used, and therefore it won't reallocate its
3249 buffers (which makes no other sense to me than a bug). It results
3250 in warnings for `unused: yy_flex_realloc'.
3252 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
3254 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3255 (MUSCLE_INSERT_PREFIX): ...to there.
3256 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3257 (MUSCLE_INSERT_PREFIX): Move from here...
3259 * src/bison.hairy: Add a section directive. Put braces around muscle
3260 names. This parser skeleton is still broken, but Bison should not
3261 choke on a bad muscle 'syntax'.
3262 * src/bison.simple: Add a section directive. Put braces around muscle
3265 * src/files.h (strsuffix, stringappend): Add declarations.
3266 (tab_extension): Add declaration.
3267 (short_base_name): Add declaration.
3269 * src/files.c (strsuffix, stringappend): No longer static. These
3270 functions are used in the skeleton parser.
3271 (tab_extension): New.
3272 (compute_base_names): Use the computations done in this function
3273 to guess if the generated parsers should have '.tab' in their
3275 (short_base_name): No longer static.
3277 * src/output.c (output_skeleton): New.
3278 (output): Disable call to output_master_parser, and give a try to
3279 a new skeleton handling system.
3280 (guards_output, actions_output): No longer static.
3281 (token_definitions_output, get_lines_number): No longer static.
3283 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3285 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3288 * src/parse-skel.y: New file.
3289 * src/scan-skel.l: New file.
3291 2001-12-29 Akim Demaille <akim@epita.fr>
3293 %name-prefix is broken.
3295 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3296 Adjust all dependencies.
3297 * tests/headers.at (export YYLTYPE): Strengthen this test: use
3300 Renaming yylval but not yylloc is not consistent. Now we do.
3302 * src/bison.simple: Prefix yylloc if used.
3303 * doc/bison.texinfo (Decl Summary): Document that.
3305 2001-12-29 Akim Demaille <akim@epita.fr>
3307 * doc/bison.texinfo: Promote `%long-directive' over
3309 Remove all references to fixed-output-files, yacc is enough.
3311 2001-12-29 Akim Demaille <akim@epita.fr>
3313 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3314 user prologue. These are defaults.
3315 * tests/actions.at (Mid-rule actions): Make sure the user can
3316 define YYDEBUG and YYERROR_VERBOSE.
3318 2001-12-29 Akim Demaille <akim@epita.fr>
3320 * src/output.c (header_output): Don't forget to export YYLTYPE and
3322 * tests/headers.at (export YYLTYPE): New, make sure it does.
3323 * tests/regression.at (%union and --defines, Invalid CPP headers):
3325 * tests/headers.at: here.
3327 2001-12-29 Akim Demaille <akim@epita.fr>
3329 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3331 2001-12-29 Akim Demaille <akim@epita.fr>
3333 * tests/actions.at (Mid-rule actions): Output on a single line
3336 2001-12-29 Akim Demaille <akim@epita.fr>
3338 * doc/bison.texinfo: Formatting changes.
3340 2001-12-29 Akim Demaille <akim@epita.fr>
3342 Don't store the token defs in a muscle, just be ready to output it
3343 on command. Now possible via `symbols'. Fixes a memory leak.
3345 * src/output.c (token_definitions_output): New.
3346 (output_parser, header_output): Use it.
3347 * src/reader.c (symbols_save): Remove.
3349 2001-12-29 Akim Demaille <akim@epita.fr>
3351 * src/bison.simple: Do not provide a default for YYSTYPE and
3352 YYLTYPE before the user's prologue. Otherwise it's hardly... a
3355 2001-12-29 Akim Demaille <akim@epita.fr>
3357 Mid-rule actions are simply... ignored!
3359 * src/reader.c (readgram): Be sure to attach mid-rule actions to
3360 the empty-rule associated to the dummy symbol, not to the host
3362 * tests/actions.at (Mid-rule actions): New.
3364 2001-12-29 Akim Demaille <akim@epita.fr>
3368 * src/reader.c (reader): Free grammar.
3370 2001-12-29 Akim Demaille <akim@epita.fr>
3374 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3375 since it allocates it for each state, although only one is needed.
3376 (allocate_storage): Do it here.
3378 2001-12-29 Akim Demaille <akim@epita.fr>
3380 * src/options.h, src/options.c (create_long_option_table): Rename
3382 (long_option_table_new): this, with a clearer prototype.
3383 (percent_table): Remove, unused,
3384 * src/getargs.c (getargs): Adjust.
3386 2001-12-29 Akim Demaille <akim@epita.fr>
3388 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3389 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3392 2001-12-29 Akim Demaille <akim@epita.fr>
3394 * src/lalr.c (build_relations): Rename `states' as `states1'.
3395 Sorry, I don't understand exactly what it is, no better name...
3397 2001-12-29 Akim Demaille <akim@epita.fr>
3399 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3400 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3401 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3404 2001-12-29 Akim Demaille <akim@epita.fr>
3406 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3409 2001-12-29 Akim Demaille <akim@epita.fr>
3411 * src/reader.c, src/reader.h (user_toknums): Remove.
3412 Adjust all users to use symbols[i]->user_token_number.
3414 2001-12-29 Akim Demaille <akim@epita.fr>
3416 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3417 Adjust all users to use symbols[i]->prec or ->assoc.
3419 2001-12-29 Akim Demaille <akim@epita.fr>
3421 * src/reader.c, src/reader.h (tags): Remove.
3422 Adjust all users to use symbols[i]->tag.
3424 2001-12-29 Akim Demaille <akim@epita.fr>
3426 * src/gram.h, src/gram.c (symbols): New, similar to state_table
3428 * src/reader.c (packsymbols): Fill this table.
3430 * src/conflicts.c (resolve_sr_conflict): Adjust.
3431 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3433 Use symbols[i]->tag instead of tags[i].
3435 2001-12-29 Akim Demaille <akim@epita.fr>
3437 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3438 In addition, put a comment in there, to replace...
3439 * tests/regression.at (%union and C comments): Remove.
3441 2001-12-29 Akim Demaille <akim@epita.fr>
3443 * tests/regression.at (Web2c Actions): Blindly move the actual
3444 output as expected output. The contents *seem* right to me, but I
3445 can't pretend reading perfectly parser tables... Nonetheless, all
3446 the other tests pass correctly, the table look OK, even though the
3447 presence of `$axiom' is to be noted: AFAICS it is useless (but
3450 2001-12-29 Akim Demaille <akim@epita.fr>
3452 * src/reader.c (readgram): Don't add the rule 0 if there were no
3453 rules read. In other words, add it _after_ having performed
3454 grammar sanity checks.
3455 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3457 2001-12-29 Akim Demaille <akim@epita.fr>
3459 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3460 visible, and some states have now a different number.
3462 2001-12-29 Akim Demaille <akim@epita.fr>
3464 * src/reader.c (readgram): Bind the initial rule's lineno to that
3466 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3467 (Solved SR Conflicts): Adjust rule 0's line number.
3469 2001-12-29 Akim Demaille <akim@epita.fr>
3471 Fix the `GAWK Grammar' failure.
3473 * src/LR0.c (final_state): Initialize to -1 so that we do compute
3474 the reductions of the first state which was mistakenly confused
3475 with the final state because precisely final_state was initialized
3477 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3478 now noticed by Bison.
3479 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3480 have a reduction on $default.
3482 2001-12-29 Akim Demaille <akim@epita.fr>
3484 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3486 * src/closure.c (print_closure): Likewise.
3487 * src/derives.c (print_derives): Likewise.
3488 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3491 2001-12-29 Akim Demaille <akim@epita.fr>
3493 * src/lalr.c (lookaheads_print): New.
3494 (lalr): Call it when --trace-flag.
3495 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3498 2001-12-29 Akim Demaille <akim@epita.fr>
3500 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3501 when walking through ritem, even via rule->rhs.
3502 * src/reduce.c (dump_grammar, useful_production, reduce_output)
3503 (useful_production, useless_nonterminals): Likewise.
3504 (reduce_grammar_tables): Likewise, plus update nritems.
3505 * src/nullable.c (set_nullable): Likewise.
3506 * src/lalr.c (build_relations): Likewise.
3507 * tests/sets.at (Nullable): Adjust.
3508 Fortunately, now, the $axiom is no longer nullable.
3510 2001-12-29 Akim Demaille <akim@epita.fr>
3512 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3514 * src/gram.c (ritem_longest_rhs): Likewise.
3515 * src/reduce.c (nonterminals_reduce): Likewise.
3516 * src/print_graph.c (print_graph): Likewise.
3517 * src/output.c (output_rule_data): Likewise.
3518 * src/nullable.c (set_nullable): Likewise.
3520 2001-12-29 Akim Demaille <akim@epita.fr>
3522 * src/output.c: Comment changes.
3524 2001-12-27 Paul Eggert <eggert@twinsun.com>
3526 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3527 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3528 Sparc, as they were causing more porting problems than the
3529 (minor) performance improvement was worth.
3531 Also, catch up with 1.31's YYSTD.
3533 2001-12-27 Akim Demaille <akim@epita.fr>
3535 * src/output.c (output_gram): Rely on nritems, not the
3536 0-sentinel. See below.
3537 Use -1 as separator, not 0.
3538 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3539 Rely on -1 as separator in yyrhs, instead of 0.
3540 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3541 twice `Now at end of input', therefore there are two lines less to
3544 2001-12-27 Akim Demaille <akim@epita.fr>
3546 * tests/regression.at (Unresolved SR Conflicts):
3547 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3550 2001-12-27 Akim Demaille <akim@epita.fr>
3552 * src/LR0.c (new_state): Recognize the final state by the fact it
3553 is reached by eoftoken.
3554 (insert_start_shifting_state, insert_eof_shifting_state)
3555 (insert_accepting_state, augment_automaton): Remove, since now
3556 these states are automatically computed from the initial state.
3557 (generate_states): Adjust.
3558 * src/print.c: When reporting a rule number to the user, substract
3559 1, so that the axiom rule is rule 0, and the first user rule is 1.
3560 * src/reduce.c: Likewise.
3561 * src/print_graph.c (print_core): For the time being, just as for
3562 the report, depend upon --trace-flags to dump the full set of
3564 * src/reader.c (readgram): Once the grammar read, insert the rule
3565 0: `$axiom: START-SYMBOL $'.
3566 * tests/set.at: Adjust: rule 0 is now displayed, and since the
3567 number of the states has changed (the final state is no longer
3568 necessarily the last), catch up.
3570 2001-12-27 Akim Demaille <akim@epita.fr>
3572 Try to make the use of the eoftoken valid. Given that its value
3573 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3574 is used instead of > 0 where appropriate, (ii), depend upon nritems
3575 instead of the 0-sentinel.
3577 * src/gram.h, src/gram.c (nritems): New.
3578 Expected to be duplication of nitems, but for the time being...
3579 * src/reader.c (packgram): Assert nritems and nitems are equal.
3580 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3581 * src/closure.c (print_closure, print_fderives): Likewise.
3582 * src/gram.c (ritem_print): Likewise.
3583 * src/print.c (print_core, print_grammar): Likewise.
3584 * src/print_graph.c: Likewise.
3586 2001-12-27 Akim Demaille <akim@epita.fr>
3588 * src/main.c (main): If there are complains after grammar
3589 reductions, then output the report anyway if requested, then die.
3590 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3591 * src/reader.c (eoftoken): New.
3592 (parse_token_decl): If the token being defined has value `0', it
3594 (packsymbols): No longer hack `tags' to insert `$' by hand.
3595 Be sure to preserve the value of the eoftoken.
3596 (reader): Make sure eoftoken is defined.
3597 Initialize nsyms to 0: now eoftoken is created just like the others.
3598 * src/print.c (print_grammar): Don't special case the eof token.
3599 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3600 lie anyway, albeit pleasant.
3601 * tests/calc.at: Exercise error messages with eoftoken.
3602 Change the grammar so that empty input is invalid.
3603 Adjust expectations.
3604 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3606 2001-12-27 Akim Demaille <akim@epita.fr>
3608 * configure.in: Check the protos of strchr ans strspn.
3609 Replace strchr if needed.
3610 * src/system.h: Provide the protos of strchr, strspn and memchr if
3612 * lib/strchr.c: New.
3613 * src/reader.c (symbols_save): Use strchr.
3615 2001-12-27 Akim Demaille <akim@epita.fr>
3617 * src/print.c, src/print_graph.c (escape): New.
3618 Use it to quote the TAGS outputs.
3619 * src/print_graph.c (print_state): Now errors are in red, and
3620 reductions in green.
3621 Prefer high to wide: output the state number on a line of its own.
3623 2001-12-27 Akim Demaille <akim@epita.fr>
3625 * src/state.h, src/state.c (reductions_new): New.

3646 2001-12-27 Akim Demaille <akim@epita.fr>
3648 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3649 * src/print.c: here.
3650 (lookaheadset, shiftset): New, used as additional storage by
3652 (print_results): Adjust.
3653 (print_shifts, print_gotos, print_errs): New, extracted from...
3654 (print_actions): here.
3655 * src/print_graph.c (print_actions): Remove dead code.
3657 2001-12-27 Akim Demaille <akim@epita.fr>
3659 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3662 2001-12-27 Akim Demaille <akim@epita.fr>
3664 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

3667 2001-12-27 Akim Demaille <akim@epita.fr>
3669 * src/lalr.c (set_goto_map): Remove a wrong but benign loop

3674 * src/reader.c (packgram): Catch nitems overflows.
3676 2001-12-27 Akim Demaille <akim@epita.fr>
3678 * src/files.c, src/files.h (guard_obstack): Remove.
3679 * src/output.c (output): Adjust.
3680 * src/reader.c (parse_braces): New, factoring...
3681 (copy_action, copy_guard): these two which are renamed as...
3682 (parse_action, parse_guard): these.
3683 As a voluntary consequence, using braces around guards is now
3686 2001-12-27 Akim Demaille <akim@epita.fr>
3688 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3689 * src/reader.c (symbol_list): `guard' and `guard_line' are new
3691 (symbol_list_new): Adjust.
3692 (copy_action): action_line is the first line, not the last.
3693 (copy_guard): Just as for actions, store the `action' only, not
3694 the switch/case/break flesh.
3695 Don't parse the user action that might follow the guard, let...
3696 (readgram): do it, i.e., now, there can be an action after a
3698 In other words the guard is just explicitly optional.
3700 * src/output.c (guards_output): New.
3701 (output_parser): Call it when needed.
3702 (output): Also free the guard and attrs obstacks.
3703 * src/files.c, src/files.h (obstack_save): Remove.
3704 (output_files): Remove.
3705 As a result, if one needs the former `.act' file, using an
3706 appropriate skeleton which requires actions and guards is now
3708 * src/main.c (main): Adjust.
3709 * tests/semantic.at: New.
3710 * tests/regression.at: Use `input.y' as input file name.
3711 Avoid 8+3 problems by requiring input.c when the test needs the

3716 * src/reader.c (symbol_list_new): Be sure to initialize all the
3719 2001-12-27 Akim Demaille <akim@epita.fr>
3721 All the hacks using a final pseudo state are now useless.
3723 * src/LR0.c (set_state_table): state_table holds exactly nstates.
3724 * src/lalr.c (nLA): New.
3725 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3726 instead of lookaheadsp from the pseudo state (nstate + 1).
3728 2001-12-27 Akim Demaille <akim@epita.fr>
3730 * src/output.c (action_row, token_actions): Use a state_t instead
3731 of a integer, and nlookaheads instead of the following state's
3734 2001-12-27 Akim Demaille <akim@epita.fr>
3736 * src/conflicts.c (log_resolution, flush_shift)
3737 (resolve_sr_conflict, set_conflicts, solve_conflicts)
3738 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3739 (conflicts_print, print_reductions): Use a state_t instead of an
3740 integer when referring to a state.
3741 As much as possible, depend upon nlookaheads, instead of the
3742 `lookaheadsp' member of the following state (since lookaheads of
3743 successive states are successive, the difference between state n + 1
3744 and n served as the number of lookaheads for state n).
3745 * src/lalr.c (add_lookback_edge): Likewise.
3746 * src/print.c (print_core, print_actions, print_state)
3747 (print_results): Likewise.

3754 * src/bison.hairy: Formatting/comment changes.
3756 Remove `register' indications.
3757 Add plenty of `static'.
3759 2001-12-27 Akim Demaille <akim@epita.fr>
3761 * src/output.c (prepare): Drop the muscle `ntbase' which
3763 * src/bison.simple: Formatting/comment changes.
3764 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3765 is an undocumented synonym.
3767 2001-12-22 Akim Demaille <akim@epita.fr>
3769 * src/output.c (output_table_data): Change the prototype to use
3770 `int' for array ranges: some invocations do pass an int, not a
3772 Reported by Wayne Green.
3774 2001-12-22 Akim Demaille <akim@epita.fr>
3776 Some actions of web2c.y are improperly triggered.
3777 Reported by Mike Castle.
3779 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

3781 (Web2c Report): this.
3782 (Web2c Actions): New.
3784 2001-12-22 Akim Demaille <akim@epita.fr>
3786 Reductions in web2c.y are improperly reported.
3787 Reported by Mike Castle.
3789 * src/conflicts.c (print_reductions): Fix.
3790 * tests/regression.at (Web2c): New.
3792 2001-12-18 Akim Demaille <akim@epita.fr>
3794 Some host fail on `assert (!"foo")', which expands to
3795 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3796 Reported by Nelson Beebee.
3798 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3799 `#define it_succeeded 0' and `assert (it_succeeded)'.
3801 2001-12-17 Marc Autret <autret_m@epita.fr>
3803 * src/bison.simple: Don't hard code the skeleton line and filename.
3804 * src/output.c (output_parser): Rename 'line' as 'output_line'.
3805 New line counter 'skeleton_line' (skeleton-line muscle).
3807 2001-12-17 Paul Eggert <eggert@twinsun.com>
3809 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3810 YYDEBUG must be defined to a nonzero value.
3812 * src/bison.simple (yytname): Do not assume that the user defines
3813 YYDEBUG to a properly parenthesized expression.
3815 2001-12-17 Akim Demaille <akim@epita.fr>
3817 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3818 nlookaheads is a new member.
3820 * src/lalr.h (nlookaheads): Remove this orphan declaration.
3821 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
3824 2001-12-17 Akim Demaille <akim@epita.fr>

3827 * src/main.c (main): Don't open/close files, nor invoke lex_free,
3829 * src/reader.c (reader): Do it.
3831 2001-12-17 Akim Demaille <akim@epita.fr>
3833 * src/conflicts.c (print_reductions): Formatting changes.
3835 2001-12-17 Akim Demaille <akim@epita.fr>
3837 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
3838 (flush_reduce): New.
3839 (resolve_sr_conflict): Adjust.
3841 2001-12-17 Akim Demaille <akim@epita.fr>
3843 * src/output.c (output_obstack): Be static and rename as...
3844 (format_obstack): this, to avoid any confusion with files.c's
3846 * src/reader.h (muscle_obstack): Move to...
3847 * src/output.h: here, since it's defined in output.c.
3849 2001-12-17 Akim Demaille <akim@epita.fr>
3851 * src/output.c (action_row, save_column, default_goto)
3852 (sort_actions, matching_state, pack_vector): Better variable
3855 2001-12-17 Akim Demaille <akim@epita.fr>
3857 * src/output.c: Various formatting changes.
3859 2001-12-17 Akim Demaille <akim@epita.fr>
3861 * src/files.c (output_files): Free the output_obstack.
3862 * src/main.c (main): Call print and print_graph conditionally.
3863 * src/print.c (print): Work unconditionally.
3864 * src/print_graph.c (print_graph): Work unconditionally.
3865 * src/conflicts.c (log_resolution): Output only if verbose_flag.
3867 2001-12-16 Marc Autret <autret_m@epita.fr>
3869 * src/output.c (actions_output): Fix. When we use %no-lines,
3870 there is one less line per action.
3872 2001-12-16 Marc Autret <autret_m@epita.fr>
3874 * src/bison.simple: Remove a useless #line directive.
3875 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3876 * src/output.c (get_lines_number): New.
3877 (output_parser): Adjust, now takes care about the lines of a
3880 (actions_output): Computes the number of lines taken by actions.
3881 (output_master_parser): Insert new skeleton which is the name of
3882 the output parser file name.
3884 2001-12-15 Marc Autret <autret_m@epita.fr>
3886 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
3888 2001-12-15 Marc Autret <autret_m@epita.fr>
3890 * src/output.c (output_gram): Keep track of the hairy one.
3892 2001-12-15 Akim Demaille <akim@epita.fr>
3894 Make `make distcheck' work.
3896 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3897 system.h which uses libgettext.h.
3899 2001-12-15 Akim Demaille <akim@epita.fr>
3901 * src/nullable.c (set_nullable): Useless rules must be skipped,
3902 otherwise, since we range over their symbols, we might look at a
3903 nonterminal which no longer ``exists'', i.e., it is not counted in
3904 `nvars', hence we overflow our arrays.
3906 2001-12-15 Akim Demaille <akim@epita.fr>
3908 The header can also be produced directly, without any obstack!
3911 * src/files.c, src/files.h (defines_obstack): Remove.
3912 (compute_header_macro): Global.
3913 (defines_obstack_save): Remove.
3914 * src/reader.c (parse_union_decl): No longer output to
3915 defines_obstack: its content can be found in the `stype' muscle
3917 (output_token_translations): Merge into...
3918 (symbols_output): this.
3920 (symbols_save): this.
3922 * src/output.c (header_output): New.
3925 2001-12-15 Akim Demaille <akim@epita.fr>
3927 * src/reader.c (parse_union_decl): Instead of handling two obstack
3928 simultaneously, use one to define the `stype' muscle, and use the
3929 value of the latter to fill defines_obstack.
3930 (copy_comment): Remove.
3931 (copy_comment2): Work for a single obstack.
3933 (copy_comment): this.
3935 2001-12-15 Akim Demaille <akim@epita.fr>
3937 * src/lex.c, src/lex.h (xgetc): No longer static.
3938 * src/reader.c (parse_union_decl): Revamp.
3940 2001-12-15 Akim Demaille <akim@epita.fr>
3942 Still making progress in separating Bison into (i) input, (ii)
3943 process, (iii) output: now we can directly output the parser file
3944 without using table_obstack at all.
3946 * src/files.c, src/files.h (table_obstack): Bye bye.
3947 (parser_file_name): New.
3948 * src/files.c (compute_output_file_names): Compute it.
3949 * src/output.c (actions_output, output_parser)
3950 (output_master_parser): To a file instead of an obstack.
3952 2001-12-15 Akim Demaille <akim@epita.fr>
3954 Attach actions to rules, instead of pre-outputting them to
3957 * src/gram.h (rule_t): action and action_line are new members.
3958 * src/reader.c (symbol_list): Likewise.
3959 (copy_action): Save the actions within the rule.
3960 (packgram): Save them in rule_table.
3961 * src/output.c (actions_output): New.
3962 (output_parser): Use it on `%%actions'.
3963 (output_rule_data): Don't free rule_table.
3965 (prepare): Don't save the `action' muscle.
3966 * src/bison.simple: s/%%action/%%actions/.
3968 2001-12-15 Akim Demaille <akim@epita.fr>
3970 * src/reader.c (copy_action): When --yacc, don't append a `;'
3971 to the user action: let it fail if lacking.
3972 Suggested by Arnold Robbins and Tom Tromey.
3974 2001-12-14 Akim Demaille <akim@epita.fr>
3976 * src/lex.c (literalchar): Simply return the char you decoded, non
3977 longer mess around with obstacks and int pointers.
3980 2001-12-14 Akim Demaille <akim@epita.fr>
3982 * src/lex.c (literalchar): Don't escape the special characters,
3983 just decode them, and keep them as char (before, eol was output as
3984 the 2 char string `\n' etc.).
3985 * src/output.c (output_rule_data): Use quotearg to output the
3988 2001-12-13 Paul Eggert <eggert@twinsun.com>
3990 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3991 Do not infringe on the global user namespace when using C++.
3992 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3993 All uses of `fprintf' and `stderr' changed.
3995 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3997 2001-12-13 Akim Demaille <akim@epita.fr>
3999 The computation of nullable is broken: it doesn't handle empty
4002 * tests/torture.at (GNU AWK Grammar): New.
4003 * tests/sets.at (Nullable): New.
4004 * src/nullable.c (set_nullable): Instead of blindly looping over
4005 `ritems', loop over the rules, and then over their rhs's.
4007 Work around Autotest bugs.
4009 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4010 frame, because Autotest understand lines starting with a `+' as
4011 traces from the shell. Then, they are not processed properly.
4012 Admittedly an Autotest bug, but we don't have time to wait for
4013 Autotest to catch up.
4014 * tests/regression.at (Broken Closure): Adjust to the new table
4017 * tests/sets.at: here.
4019 2001-12-13 Akim Demaille <akim@epita.fr>
4021 * src/closure.c (closure): Use nrules instead of playing tricks
4024 2001-12-13 Akim Demaille <akim@epita.fr>
4026 * src/print.c (print_actions): Output the handling of `$' as the
4027 traces do: shifting the token EOF. Before EOF was treated as a
4029 * tests/regression.at: Adjust some tests.
4030 * src/print_graph.c (print_core): Complete the set of items via
4031 closure. The next-to-final and final states are still unsatisfying,
4032 but that's to be addressed elsewhere.
4033 No longer output the rule numbers, but do output the state number.
4034 A single loop for the shifts + gotos is enough, but picked a
4035 distinct color for each.
4036 (print_graph): Initialize and finalize closure.
4038 2001-12-13 Akim Demaille <akim@epita.fr>
4040 * src/reader.c (readgram): Remove dead code, an strip useless
4042 (get_type): Remove, unused.
4044 2001-12-12 Akim Demaille <akim@epita.fr>
4046 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4047 on that of lib/error.c.
4049 2001-12-12 Akim Demaille <akim@epita.fr>
4051 Some hosts don't like `/' in includes.
4053 * src/system.h: Include libgettext.h without qualifying the path.
4054 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4057 2001-12-11 Marc Autret <autret_m@epita.fr>
4059 * src/output.c (output_parser): Remove useless muscle.
4061 2001-12-11 Marc Autret <autret_m@epita.fr>
4063 * src/bison.simple: Remove #line just before %%epilogue. It
4064 is now handled in ...
4065 * src/reader.c (read_additionnal_code): Add the output of a
4066 #line for the epilogue.
4068 2001-12-10 Marc Autret <autret_m@epita.fr>
4070 * src/reader.c (copy_definition): Re-use CPP-outed code which
4071 replace precedent remove.
4072 * src/bison.simple: Remove #line before %%prologue because
4073 %%input-line is wrong at this time.
4075 2001-12-10 Marc Autret <autret_m@epita.fr>
4077 * src/reader.c (symbols_output): Clean up.
4078 * src/output.c (output_gram, output): Clean up.
4080 2001-12-10 Akim Demaille <akim@epita.fr>
4082 * src/lalr.c (initialize_lookaheads): New. Extracted from...
4083 * src/LR0.c (set_state_table): here.
4084 * src/lalr.c (lalr): Call it.
4086 2001-12-10 Akim Demaille <akim@epita.fr>
4088 * src/state.h (shifts): Remove the `number' member: shifts are
4089 attached to state, hence no longer need to be labelled with a
4092 2001-12-10 Akim Demaille <akim@epita.fr>
4094 Now that states have a complete set of members, the linked list of
4095 shifts is useless: just fill directly the state's shifts member.
4097 * src/state.h (shifts): Remove the `next' member.
4098 * src/LR0.c (first_state, last_state): Remove.
4100 (augment_automaton): Don't look for the shifts that must be added
4101 a shift on EOF: it is those of the state we looked for! But now,
4102 since shifts are attached, it is no longer needed to looking
4103 merely by its id: its number.
4105 2001-12-10 Akim Demaille <akim@epita.fr>
4107 * src/LR0.c (augment_automaton): Better variable locality.
4108 Remove an impossible branch: if there is a state corresponding to
4109 the start symbol being shifted, then there is shift for the start
4110 symbol from the initial state.
4112 2001-12-10 Akim Demaille <akim@epita.fr>
4114 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4115 only when appropriate: when insert_start_shifting_state' is not
4117 * tests/regression.at (Rule Line Numbers): Adjust.
4119 2001-12-10 Akim Demaille <akim@epita.fr>
4121 * src/LR0.c (augment_automaton): Now that all states have shifts,
4122 merge the two cases addition shifts to the initial state.
4124 2001-12-10 Akim Demaille <akim@epita.fr>
4126 * src/lalr.c (set_state_table): Move to...
4128 * src/lalr.c (lalr): Don't call it...
4129 * src/LR0.c (generate_states): do it.
4130 * src/LR0.h (first_state): Remove, only the table is used.
4132 2001-12-10 Akim Demaille <akim@epita.fr>
4134 * src/LR0.h (first_shift, first_reduction): Remove.
4135 * src/lalr.c: Don't use first_shift: find shifts through the
4138 2001-12-10 Akim Demaille <akim@epita.fr>
4140 * src/LR0.c: Attach shifts to states as soon as they are
4142 * src/lalr.c (set_state_table): Instead of assigning shifts to
4143 state, just assert that the mapping was properly done.
4145 2001-12-10 Akim Demaille <akim@epita.fr>
4147 * src/LR0.c (insert_start_shift): Rename as...
4148 (insert_start_shifting_state): this.
4149 (insert_eof_shifting_state, insert_accepting_state): New.
4150 (augment_automaton): Adjust.
4151 Better locality of the variables.
4152 When looking if the start_symbol is shifted from the initial
4153 state, using `while (... symbol != start_symbol ...)' sounds
4154 better than `while (... symbol < start_symbol ...)': If fail
4155 to see how the order between symbols could be relevant!
4157 2001-12-10 Akim Demaille <akim@epita.fr>
4159 * src/getargs.h: Don't declare `spec_name_prefix' and
4160 `spec_file_prefix', declared by src/files.h.
4161 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".

4163 * src/output.c (prepare): Adjust.
4164 * src/reader.c (symbols_output): Likewise.

4167 2001-12-10 Akim Demaille <akim@epita.fr>
4169 * src/muscle_tab.c (muscle_init): NULL is a better default than
4172 2001-12-10 Akim Demaille <akim@epita.fr>
4174 * src/reader.c (reader): Calling symbols_output once is enough.
4176 2001-12-10 Akim Demaille <akim@epita.fr>
4178 Now that states have a complete set of members, the linked list of
4179 reductions is useless: just fill directly the state's reductions
4182 * src/state.h (struct reductions): Remove member `number' and
4184 * src/LR0.c (first_reduction, last_reduction): Remove.
4185 (save_reductions): Don't link the new reductions, store them in
4187 * src/lalr.c (set_state_table): No need to attach reductions to
4188 states, it's already done.
4189 * src/output.c (output_actions): No longer free the shifts, then
4190 the reductions, then the states: free all the states and their
4193 2001-12-10 Akim Demaille <akim@epita.fr>
4195 * src/options.c (OPTN, DRTV, BOTH): New.
4196 (option_table): Use them.
4198 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4199 the job of system.h.
4200 * src/options.c: Don't include stdio.h and xalloc.h for the same
4203 2001-12-10 Akim Demaille <akim@epita.fr>
4205 * src/output.c (output, prepare): Make sure the values of the
4206 muscles `action' and `prologue' are 0-terminated.
4208 2001-12-10 Akim Demaille <akim@epita.fr>
4210 Clean up GCC warnings.

4225 * tests/Makefile.am: Adjust.
4227 2001-12-10 Akim Demaille <akim@epita.fr>
4229 One structure for states is enough, even though theoretically
4230 there are LR(0) states and LALR(1) states.
4232 * src/lalr.h (state_t): Remove.
4233 (state_table): Be state_t **, not state_t *.
4234 * src/state.h (core, CORE_ALLOC): Rename as...
4235 (state_t, STATE_ALLOC): this.
4236 Add the LALR(1) members: shifts, reductions, errs.
4237 * src/LR0.c (state_table): Rename as...
4238 (state_hash): this, to avoid name clashes with the global
4240 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4241 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
4243 2001-12-10 Akim Demaille <akim@epita.fr>
4245 Bison dumps core on bash.y.
4246 Reported by Pascal Bart.
4248 * src/warshall.c (bitmatrix_print): New.
4250 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4251 j must be the outer loop.
4252 * tests/regression.at (Broken Closure): New.
4254 2001-12-05 Akim Demaille <akim@epita.fr>
4256 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and

4264 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4266 (state_t.reductions, state_t.shifts): this.
4268 2001-12-05 Akim Demaille <akim@epita.fr>
4270 * src/reduce.c (reduce_grammar_tables): No longer disable the
4271 removal of useless rules via CPP but via `if (0)', so that the
4272 compiler still check the code is valid.
4273 For instance, it should have noticed `rline' no longer exists: use
4274 the `line' member of rule_t.
4275 * src/gram.c (dummy, rline): Remove, unused.
4277 2001-12-05 Akim Demaille <akim@epita.fr>
4279 * src/output.c (pack_vector): Use assert, not berror.
4280 * src/main.c (berror): Remove, unused.
4282 2001-12-05 Akim Demaille <akim@epita.fr>
4284 New experimental feature: if --verbose --trace output all the
4285 items of a state, not only its kernel.
4287 * src/print.c (print_core): If `trace_flag', then invoke closure
4288 before outputting the items of the state (print_core is no longer
4289 a correct name them).
4290 (print_results): Invoke new_closure/free_closure if needed.
4292 2001-12-05 Akim Demaille <akim@epita.fr>

4301 (closure): Use it for printing input and output.
4303 2001-12-05 Akim Demaille <akim@epita.fr>
4305 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4306 indexed by nonterminals.
4308 2001-12-05 Akim Demaille <akim@epita.fr>
4310 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

4330 locality, BITISSET, RESETBIT etc.
4332 2001-12-05 Akim Demaille <akim@epita.fr>
4334 Pessimize the code to simplify it: from now on, all the states
4335 have a valid SHIFTS, which NSHIFTS is possibly 0.
4337 * src/LR0.c (shifts_new): Be global and move to..
4338 * src/state.c, src/state.h: here.
4339 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4340 * src/print_graph: Adjust.
4342 2001-12-05 Akim Demaille <akim@epita.fr>
4344 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4345 * src/conflicts.c: Use it.
4346 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4347 incorrectly ``simplified''.

4351 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4352 using the good o' techniques: arrays not pointers, variable

4362 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4363 (print_reductions): De-obfuscate using the good o' techniques:

4401 Use arrays instead of pointers.
4403 2001-12-05 Akim Demaille <akim@epita.fr>
4405 * src/lalr.c (maxrhs): Move to...
4406 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4407 * src/lalr.c (build_relations): Adjust.
4409 2001-12-05 Akim Demaille <akim@epita.fr>
4411 * src/lalr.c (transpose): Free the memory allocated to the
4412 argument, as it is replaced by the results by the unique caller.
4413 (build_relations): Merely invoke transpose: it handles the memory
4415 Improve variable locality.
4416 Avoid variables used as mere abbreviations.
4417 (compute_lookaheads): Use arrays instead of pointers.
4419 2001-12-05 Akim Demaille <akim@epita.fr>
4421 * src/lalr.c (initialize_F): Improve variable locality.

4426 * src/derives.c (print_derives): Display the ruleno.
4427 * src/lalr.c (initialize_F, transpose): Better variable locality
4428 to improve readability.
4429 Avoid variables used as mere abbreviations.
4431 2001-12-05 Akim Demaille <akim@epita.fr>
4433 * src/lalr.c (traverse): Use arrays instead of pointers.
4435 2001-12-05 Akim Demaille <akim@epita.fr>
4437 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4438 the handling of squeue.
4439 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4441 2001-12-05 Akim Demaille <akim@epita.fr>
4443 Because useless nonterminals are now kept alive (instead of being
4444 `destroyed'), we now sometimes examine them, and store information
4445 related to them. Hence we need to know their number, and adjust
4448 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4450 * src/LR0.c (allocate_itemsets): The memory allocated to
4451 `symbol_count' was used for two different purpose: once to count
4452 the number of occurrences of each symbol, and later reassigned to
4453 `shift_symbol', containing the symbol that can be shifted from a
4455 Deobfuscate, i.e., allocate, use and free `symbol_count' here
4457 (new_itemsets): Allocate `shift_symbol' here.
4458 (allocate_itemsets): symbol_count includes useless nonterminals.
4460 (free_storage): Use `free', not `XFREE', for pointers that cannot
4463 2001-12-05 Akim Demaille <akim@epita.fr>
4465 * src/nullable.c (set_nullable): Deobfuscate the handling of
4467 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4469 2001-12-05 Akim Demaille <akim@epita.fr>
4471 * src/gram.c, src/gram.h (ritem_print): New.
4472 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4473 (This useless function was defined only to work around VMS linkers
4474 that can't handle compilation units with variables only).
4475 * src/reduce.c (dump_grammar): Use it to trace the construction of
4478 2001-12-04 Paul Eggert <eggert@twinsun.com>
4480 * src/bison.simple (union yyalloc): Change member names
4481 to be the same as the stack names.
4482 (yyparse): yyptr is now union yyalloc *, not char *.
4483 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
4484 and may generate better code on some machines.
4485 (yystpcpy): Use prototype if __STDC__ is defined, not just
4486 if __cplusplus is defined.
4488 2001-11-30 Akim Demaille <akim@epita.fr>
4490 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4491 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU

4493 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4494 Include WARNING_CFLAGS here.
4495 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared

4500 * lib/quotearg.h (quotearg_n, quotearg_n_style):
4501 First arg is int, not unsigned.
4502 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4503 (SIZE_MAX, UINT_MAX): New macros.
4504 (quotearg_n_options): Abort if N is negative.
4505 Avoid overflow check on hosts where size_t is 64 bits and int
4506 is 32 bits, as overflow is impossible there.
4507 Fix off-by-one typo that caused unnecessary reallocation.
4509 2001-11-29 Paul Eggert <eggert@twinsun.com>
4511 Name space cleanup in generated parser.
4513 * doc/bison.texinfo (Bison Parser): Discuss system headers
4514 and their effect on the user name space.
4517 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4518 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4519 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4521 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
4522 on user names when possible.
4524 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4525 Simplify test for whather <alloca.h> exists.
4527 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4529 (<stdio.h>): Include if YYDEBUG.
4531 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
4532 ! defined (yyoverflow) && ! defined (yymemcpy).
4534 (yymemcpy, yyparse): Rename local variables as needed so that
4535 they all begin with 'yy'.
4537 (yystrlen, yystpcpy): New functions.
4539 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4542 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
4543 instead of relying on string.h functions. Use YYSTACK_ALLOC
4544 and YYSTACK_FREE instead of malloc and free.
4546 2001-11-30 Akim Demaille <akim@epita.fr>
4548 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4549 before their first uses.

4552 2001-11-30 Akim Demaille <akim@epita.fr>
4554 * tests/reduce.at (Useless Nonterminals): Fix.
4556 2001-11-30 Akim Demaille <akim@epita.fr>
4558 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4559 if body instead of `;' to pacify GCC's warnings.
4561 2001-11-30 Akim Demaille <akim@epita.fr>
4563 Instead of mapping the LHS of unused rules to -1, keep the LHS
4564 valid, but flag the rules as invalid.
4566 * src/gram.h (rule_t): `useful' is a new member.
4567 * src/print.c (print_grammar): Adjust.
4568 * src/derives.c (set_derives): Likewise.
4569 * src/reader.c (packgram, reduce_output): Likewise.
4570 * src/reduce.c (reduce_grammar_tables): Likewise.
4571 * tests/reduce.at (Underivable Rules, Useless Rules): New.
4573 2001-11-30 Akim Demaille <akim@epita.fr>

4576 * src/print.c (print_results, print_grammar): Likewise.
4577 * tests/regression.at (Rule Line Numbers)
4578 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4580 2001-11-30 Akim Demaille <akim@epita.fr>
4582 * src/reduce.c (nonterminals_reduce): Instead of throwing away
4583 useless nonterminals, move them at the end of the symbol arrays.
4584 (reduce_output): Adjust.
4585 * tests/reduce.at (Useless Nonterminals): Adjust.
4587 2001-11-30 Akim Demaille <akim@epita.fr>

4597 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4598 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4600 (union yyalloc): New type.
4601 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4602 an arbitrary restriction on hosts where size_t is wider than int.
4604 (yyparse): Don't dump core if alloca or malloc fails; instead, report
4605 a parser stack overflow. Allocate just one block of memory for all
4606 three stacks, instead of allocating three blocks; this typically is
4607 faster and reduces fragmentation.
4609 Do not limit the number of items in the stack to a value that fits
4610 in 'int', as this is an arbitrary limit on hosts with 64-bit
4611 size_t and 32-bit int.
4613 2001-11-29 Marc Autret <autret_m@epita.fr>
4615 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4616 of defining YYERROR_VERBOSE.

4628 * src/output.h: And put its extern declaration here.
4629 * src/output.c (error_verbose): Define here.
4630 (prepare): Echo name modification.
4631 * src/getargs.h: Clean its extern declaration.
4632 * src/getargs.c (error_verbose_flag): Remove.
4633 (getargs): Remove case 'e'.

4661 2001-11-28 Akim Demaille <akim@epita.fr>
4663 * src/closure.c (closure): `b' and `ruleno' denote the same value:
4666 2001-11-28 Akim Demaille <akim@epita.fr>
4668 * src/closure.c (closure): Instead of looping over word in array
4669 then bits in words, loop over bits in array.
4671 2001-11-28 Akim Demaille <akim@epita.fr>
4673 * src/closure.c (closure): No longer optimize the special case
4674 where all the bits of `ruleset[r]' are set to 0, to make the code
4677 2001-11-28 Akim Demaille <akim@epita.fr>
4679 * src/closure.c (closure): `r' and `c' are new variables, used to
4680 de-obfuscate accesses to RULESET and CORE.
4682 2001-11-28 Akim Demaille <akim@epita.fr>
4684 * src/reduce.c (reduce_print): Use ngettext.

6416 * src/conflicts.c (conflict_report): Be sure not to append to res
6417 between two calls, which could happen if both first sprintf were

6423 New, from fileutils 4.0.37.
6424 * configure.in: Require Autoconf 2.49c. I took some time before
6425 making this decision. This is the only way out for portability
6426 issues in Bison, it would mean way too much duplicate effort to
6427 import in Bison features implemented in 2.49c since 2.13.
6428 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

6475 introduces a guaranteed SEGV for semantic parsers.

6552 * src/output.c (output_parser): Compute the `#line' lines when
6554 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
6555 Suggested by Hans Aberg.
6557 2000-12-19 Akim Demaille <akim@epita.fr>

6613 prevents type checking.
6614 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't

6695 (done): Rename as...
6696 (output_files): this.

6699 it no longer has to remove tmp files, just call `output_files'
6700 when there are no errors.
6702 2000-11-02 Akim Demaille <akim@epita.fr>
6704 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
6705 `unlink': it's no longer used.
6706 * src/files.h: Formatting changes.

6807 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6809 * tests/regression.m4: New file.
6810 Include the core of the sample provided by Piotr Gackiewicz.

6834 translation, move some `\n' out of the translated strings.
6836 2000-10-02 Akim Demaille <akim@epita.fr>
6838 The location tracking mechanism is precious for parse error
6839 messages. Nevertheless, it is enabled only when `@n' is used in
6840 the grammar, which is a different issue (you can use it in error
6841 message, but not in the grammar per se). Therefore, there should
6842 be another means to enable it.

6847 * src/lex.c (percent_table): Support `%locations'.

6857 In addition replace each `flag' with `_flag'.
6859 2000-10-02 Akim Demaille <akim@epita.fr>
6861 Also test parse error messages, including with YYERROR_VERBOSE.
6863 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6865 Use it to check the computations.
6866 Use it to check `nonassoc' is honored.

6872 2000-10-02 Akim Demaille <akim@epita.fr>
6874 Test also `--verbose', `--defines' and `--name-prefix'. Testing
6875 the latter demonstrates a flaw in the handling of non debugging
6876 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6877 was used in order to simplify:
6893 unfortunately this leads to a CPP conflict when
6894 `--name-prefix=foo' is used since it produces `#define yydebug
6897 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6898 (YYDPRINTF): New macro.
6900 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6902 Also test `--verbose', `--defines' and `--name-prefix'.
6904 2000-10-02 Akim Demaille <akim@epita.fr>
6906 Improve the readability of the produced parsers.
6908 * src/bison.s1: Formatting changes.
6909 Improve the comment related to the `$' mark.
6910 (yydefault): Don't fall through to `yyresume': `goto' there.
6911 * src/output.c (output_parser): When the `$' is met, skip the end
6913 New variable, `number_of_dollar_signs', to check there's exactly
6914 one `$' in the parser skeleton.
6916 2000-10-02 Akim Demaille <akim@epita.fr>
6918 * lib/xstrdup.c: New file, from the fileutils.
6919 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6920 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6921 instead of strlen + xmalloc + strcpy.
6922 * src/symtab.c (copys): Remove, use xstrdup instead.
6924 2000-10-02 Akim Demaille <akim@epita.fr>
6926 * src/gram.h (associativity): New enum type which replaces the
6927 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6928 `right_assoc', `left_assoc' and `non_assoc'.
6929 Adjust all dependencies.
6930 * src/reader.c: Formatting changes.

6932 `reader_output_yylsp'.
6933 * src/symtab.h (symbol_class): New enum type which replaces the
6934 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

6941 Adjust dependencies.
6943 2000-10-02 Akim Demaille <akim@epita.fr>
6945 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6946 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6947 difficult and introduced a lot of core dump. It turns out that
6948 Bison used an implementation of `xmalloc' based on `calloc', and
6949 at various places it does depend upon the initialization to 0. I
6950 have not tried to isolate the pertinent places, and all the former
6951 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6952 someone should address this issue.
6954 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

7053 2000-10-02 Akim Demaille <akim@epita.fr>
7055 `user_toknums' is output as a `short[]' in `output.c', while it is
7056 defined as a `int[]' in `reader.c'. For consistency with the
7057 other output tables, `user_toknums' is now defined as a table of

7101 * src/system.h: Define PARAMS.
7102 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

7324 of the lhs of the rule (by default ranging from the location of
7325 the first symbol of the rhs, to the location of the last symbol,
7326 or, if the rhs is empty, YYLLOC).
7328 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7330 (yyparse): When providing a default semantic action, provide a
7331 default location action.
7332 (after the $): No longer change `*YYLSP', just stack YYLOC the
7333 same way you stack YYVAL.
7334 * src/reader.c (read_declarations): Use warns.
7335 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

7361 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7362 One `#if YYDEBUG' remains, since it uses variables which are
7363 defined only if `YYDEBUG != 0'.
7365 2000-03-16 Akim Demaille <akim@epita.fr>
7367 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

7387 Bump to bison 1.28a, 1.29 has never been released.
7388 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
7389 handled via src/Makefile.am.
