3 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
4 the same width as int. This reapplies a hunk of the 2002-08-12 patch
5 <http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
6 which was inadvertently undone by the 2002-09-30 patch.

110 to BITSET_WINDEX_MAX.
112 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
113 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,
114 since we now return the bitset_bindex type (not int).

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

510 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.

516 Strengthen `stage' portability.

608 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
609 for the time being: %locations ought to provide it to yyerror.

613 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

2982 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
2984 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2985 (prepare): Given that for the time being changesyntax is not
2986 usable in M4, rename the muscles using `-' to `_'.

3024 Fix `%nonassoc and eof'.

3095 canonical definition.
3096 * src/system.h: Use the canonical definition for PARAMS (avoids
3097 a conflict with the macro from lib/hash.h).
3099 2002-01-11 Akim Demaille <akim@epita.fr>
3101 * configure.in: Use AC_FUNC_STRNLEN.
3102 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
3104 2002-01-09 Akim Demaille <akim@epita.fr>
3106 * src/files.c, src/files.h (output_infix): New.
3107 (tab_extension): Remove.
3108 (compute_base_names): Compute the former, drop the latter.
3109 * src/output.c (prepare): Insert the muscles `output-infix', and
3111 * src/parse-skel.y (string, string.1): New.
3112 (section.header): Use it.
3113 (section.yacc): Remove.
3114 (prefix): Remove too.
3115 * src/scan-skel.l: Adjust.
3116 * src/bison.simple, src/bison.hairy: Adjust.
3118 2002-01-09 Akim Demaille <akim@epita.fr>
3120 * configure.in (WERROR_CFLAGS): Compute it.
3121 * src/Makefile.am (CFLAGS): Pass it.
3122 * tests/atlocal.in (CFLAGS): Idem.
3123 * src/files.c: Fix a few warnings.
3124 (get_extension_index): Remove, unused.
3126 2002-01-08 Akim Demaille <akim@epita.fr>
3128 * src/getargs.c (AS_FILE_NAME): New.
3129 (getargs): Use it to convert DOSish file names.
3130 * src/files.c (base_name): Rename as full_base_name to avoid
3131 clashes with `base_name ()'.
3132 (filename_split): New.
3133 (compute_base_names): N-th rewrite, using filename_split.
3135 2002-01-08 Akim Demaille <akim@epita.fr>
3137 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
3138 New, stolen from the Fileutils 4.1.
3139 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
3140 * configure.in: Check for the presence of memrchr, and of its
3143 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
3145 * lib/hash.h (__P): Added definition for this macro.
3146 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
3147 BUILT_SOURCES, to ensure they are generated first.
3148 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
3149 %error-verbose to allow bootstrapping with bison 1.30x.
3151 2002-01-06 Akim Demaille <akim@epita.fr>
3153 * src/reader.c (parse_braces): Don't fetch the next char, the
3154 convention is to fetch on entry.
3155 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
3156 'switch' without a following semicolon.
3157 * tests/regression.at (braces parsing): New.
3159 2002-01-06 Akim Demaille <akim@epita.fr>
3161 Bison is dead wrong in its RR conflict reports.
3163 * tests/torture.at (GNU Cim Grammar): New.
3164 * src/conflicts.c (count_rr_conflicts): Fix.
3166 2002-01-06 Akim Demaille <akim@epita.fr>
3168 Creating package.m4 from configure.ac causes too many problems.
3170 * tests/Makefile.am (package.m4): Create it by hand,
3171 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
3173 2002-01-06 Akim Demaille <akim@epita.fr>
3175 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
3178 2002-01-04 Paul Eggert <eggert@twinsun.com>
3180 * doc/bison.texinfo (Debugging):
3181 Remove YYSTDERR; it's no longer defined or used.
3182 Also, s/cstdio.h/cstdio/.
3184 2002-01-03 Akim Demaille <akim@epita.fr>
3186 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
3188 2002-01-03 Akim Demaille <akim@epita.fr>
3190 * src/parse-skel.y (process_skeleton): Don't bind the parser's
3191 tracing code to --trace, wait for a better --trace option, with
3194 2002-01-03 Akim Demaille <akim@epita.fr>
3196 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
3197 The ISO C++ standard is extremely clear about it: stderr is
3198 considered a macro, not a regular symbol (see table 94 `Header
3199 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
3200 Therefore std:: does not apply to it. It still does with fprintf.
3201 Also, s/cstdio.h/cstdio/.
3203 2002-01-03 Akim Demaille <akim@epita.fr>
3205 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
3206 for non system headers.
3208 2002-01-02 Akim Demaille <akim@epita.fr>
3210 Equip the skeleton chain with location tracking, runtime trace,
3211 pure parser and scanner.
3213 * src/parse-skel.y: Request a pure parser, locations, and prefix
3215 (%union): Having several members with the same type does not help
3216 type mismatches, simplify.
3217 (YYPRINT, yyprint): New.
3218 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
3221 * src/scan-skel.l: Adjust to these changes.
3222 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
3223 (LOCATION_PRINT, skel_control_t): New.
3225 2001-12-30 Akim Demaille <akim@epita.fr>
3227 * src/parse-skel.y: Get rid of the shift/reduce conflict:
3228 replace `gb' with BLANKS.
3229 * src/scan-skel.l: Adjust.
3231 2001-12-30 Akim Demaille <akim@epita.fr>
3233 * src/system.h: We don't need nor want bcopy.
3234 Throw away MS-DOS crap: we don't need getpid.
3235 * configure.in: We don't need strndup. It was even causing
3236 problems: because Flex includes the headers *before* us,
3237 _GNU_SOURCE is not defined by config.h, and therefore strndup was
3239 * lib/xstrndup.c: New.
3240 * src/scan-skel.l: Use it.
3241 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
3242 * src/parse-skel.y: Use %directives instead of #defines.
3244 2001-12-30 Akim Demaille <akim@epita.fr>
3246 * src/skeleton.h: New.
3247 * src/output.c (output_parser, output_master_parser): Remove, dead
3249 * src/output.h (get_lines_number, actions_output, guards_output)
3250 (token_definitions_output): Prototype them.
3251 * src/parse-skel.y: Add the license notice.
3252 Include output.h and skeleton.h.
3253 (process_skeleton): Returns void, and takes a single parameter.
3254 * src/scan-skel.l: Add the license notice.
3256 Don't use %option yylineno: it seems that then Flex imagines
3257 REJECT has been used, and therefore it won't reallocate its
3258 buffers (which makes no other sense to me than a bug). It results
3259 in warnings for `unused: yy_flex_realloc'.
3261 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
3263 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3264 (MUSCLE_INSERT_PREFIX): ...to there.
3265 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3266 (MUSCLE_INSERT_PREFIX): Move from here...
3268 * src/bison.hairy: Add a section directive. Put braces around muscle
3269 names. This parser skeleton is still broken, but Bison should not
3270 choke on a bad muscle 'syntax'.
3271 * src/bison.simple: Add a section directive. Put braces around muscle
3274 * src/files.h (strsuffix, stringappend): Add declarations.
3275 (tab_extension): Add declaration.
3276 (short_base_name): Add declaration.
3278 * src/files.c (strsuffix, stringappend): No longer static. These
3279 functions are used in the skeleton parser.
3280 (tab_extension): New.
3281 (compute_base_names): Use the computations done in this function
3282 to guess if the generated parsers should have '.tab' in their
3284 (short_base_name): No longer static.
3286 * src/output.c (output_skeleton): New.
3287 (output): Disable call to output_master_parser, and give a try to
3288 a new skeleton handling system.
3289 (guards_output, actions_output): No longer static.
3290 (token_definitions_output, get_lines_number): No longer static.
3292 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3294 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3297 * src/parse-skel.y: New file.
3298 * src/scan-skel.l: New file.
3300 2001-12-29 Akim Demaille <akim@epita.fr>
3302 %name-prefix is broken.
3304 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3305 Adjust all dependencies.
3306 * tests/headers.at (export YYLTYPE): Strengthen this test: use
3309 Renaming yylval but not yylloc is not consistent. Now we do.
3311 * src/bison.simple: Prefix yylloc if used.
3312 * doc/bison.texinfo (Decl Summary): Document that.
3314 2001-12-29 Akim Demaille <akim@epita.fr>
3316 * doc/bison.texinfo: Promote `%long-directive' over
3318 Remove all references to fixed-output-files, yacc is enough.
3320 2001-12-29 Akim Demaille <akim@epita.fr>
3322 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3323 user prologue. These are defaults.
3324 * tests/actions.at (Mid-rule actions): Make sure the user can
3325 define YYDEBUG and YYERROR_VERBOSE.
3327 2001-12-29 Akim Demaille <akim@epita.fr>
3329 * src/output.c (header_output): Don't forget to export YYLTYPE and
3331 * tests/headers.at (export YYLTYPE): New, make sure it does.
3332 * tests/regression.at (%union and --defines, Invalid CPP headers):
3334 * tests/headers.at: here.
3336 2001-12-29 Akim Demaille <akim@epita.fr>
3338 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3340 2001-12-29 Akim Demaille <akim@epita.fr>
3342 * tests/actions.at (Mid-rule actions): Output on a single line
3345 2001-12-29 Akim Demaille <akim@epita.fr>
3347 * doc/bison.texinfo: Formatting changes.
3349 2001-12-29 Akim Demaille <akim@epita.fr>
3351 Don't store the token defs in a muscle, just be ready to output it
3352 on command. Now possible via `symbols'. Fixes a memory leak.
3354 * src/output.c (token_definitions_output): New.
3355 (output_parser, header_output): Use it.
3356 * src/reader.c (symbols_save): Remove.
3358 2001-12-29 Akim Demaille <akim@epita.fr>
3360 * src/bison.simple: Do not provide a default for YYSTYPE and
3361 YYLTYPE before the user's prologue. Otherwise it's hardly... a
3364 2001-12-29 Akim Demaille <akim@epita.fr>
3366 Mid-rule actions are simply... ignored!
3368 * src/reader.c (readgram): Be sure to attach mid-rule actions to
3369 the empty-rule associated to the dummy symbol, not to the host
3371 * tests/actions.at (Mid-rule actions): New.
3373 2001-12-29 Akim Demaille <akim@epita.fr>
3377 * src/reader.c (reader): Free grammar.
3379 2001-12-29 Akim Demaille <akim@epita.fr>
3383 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3384 since it allocates it for each state, although only one is needed.
3385 (allocate_storage): Do it here.
3387 2001-12-29 Akim Demaille <akim@epita.fr>
3389 * src/options.h, src/options.c (create_long_option_table): Rename
3391 (long_option_table_new): this, with a clearer prototype.
3392 (percent_table): Remove, unused,
3393 * src/getargs.c (getargs): Adjust.
3395 2001-12-29 Akim Demaille <akim@epita.fr>
3397 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3398 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3401 2001-12-29 Akim Demaille <akim@epita.fr>
3403 * src/lalr.c (build_relations): Rename `states' as `states1'.
3404 Sorry, I don't understand exactly what it is, no better name...
3406 2001-12-29 Akim Demaille <akim@epita.fr>
3408 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3409 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3410 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3413 2001-12-29 Akim Demaille <akim@epita.fr>
3415 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3418 2001-12-29 Akim Demaille <akim@epita.fr>
3420 * src/reader.c, src/reader.h (user_toknums): Remove.
3421 Adjust all users to use symbols[i]->user_token_number.
3423 2001-12-29 Akim Demaille <akim@epita.fr>
3425 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3426 Adjust all users to use symbols[i]->prec or ->assoc.
3428 2001-12-29 Akim Demaille <akim@epita.fr>
3430 * src/reader.c, src/reader.h (tags): Remove.
3431 Adjust all users to use symbols[i]->tag.
3433 2001-12-29 Akim Demaille <akim@epita.fr>
3435 * src/gram.h, src/gram.c (symbols): New, similar to state_table
3437 * src/reader.c (packsymbols): Fill this table.
3439 * src/conflicts.c (resolve_sr_conflict): Adjust.
3440 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3442 Use symbols[i]->tag instead of tags[i].
3444 2001-12-29 Akim Demaille <akim@epita.fr>
3446 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3447 In addition, put a comment in there, to replace...
3448 * tests/regression.at (%union and C comments): Remove.
3450 2001-12-29 Akim Demaille <akim@epita.fr>
3452 * tests/regression.at (Web2c Actions): Blindly move the actual
3453 output as expected output. The contents *seem* right to me, but I
3454 can't pretend reading perfectly parser tables... Nonetheless, all
3455 the other tests pass correctly, the table look OK, even though the
3456 presence of `$axiom' is to be noted: AFAICS it is useless (but
3459 2001-12-29 Akim Demaille <akim@epita.fr>
3461 * src/reader.c (readgram): Don't add the rule 0 if there were no
3462 rules read. In other words, add it _after_ having performed
3463 grammar sanity checks.
3464 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3466 2001-12-29 Akim Demaille <akim@epita.fr>
3468 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3469 visible, and some states have now a different number.
3471 2001-12-29 Akim Demaille <akim@epita.fr>
3473 * src/reader.c (readgram): Bind the initial rule's lineno to that
3475 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3476 (Solved SR Conflicts): Adjust rule 0's line number.
3478 2001-12-29 Akim Demaille <akim@epita.fr>
3480 Fix the `GAWK Grammar' failure.
3482 * src/LR0.c (final_state): Initialize to -1 so that we do compute
3483 the reductions of the first state which was mistakenly confused
3484 with the final state because precisely final_state was initialized
3486 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3487 now noticed by Bison.
3488 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3489 have a reduction on $default.
3491 2001-12-29 Akim Demaille <akim@epita.fr>
3493 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3495 * src/closure.c (print_closure): Likewise.
3496 * src/derives.c (print_derives): Likewise.
3497 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3500 2001-12-29 Akim Demaille <akim@epita.fr>
3502 * src/lalr.c (lookaheads_print): New.
3503 (lalr): Call it when --trace-flag.
3504 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3507 2001-12-29 Akim Demaille <akim@epita.fr>
3509 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3510 when walking through ritem, even via rule->rhs.
3511 * src/reduce.c (dump_grammar, useful_production, reduce_output)
3512 (useful_production, useless_nonterminals): Likewise.
3513 (reduce_grammar_tables): Likewise, plus update nritems.
3514 * src/nullable.c (set_nullable): Likewise.
3515 * src/lalr.c (build_relations): Likewise.
3516 * tests/sets.at (Nullable): Adjust.
3517 Fortunately, now, the $axiom is no longer nullable.
3519 2001-12-29 Akim Demaille <akim@epita.fr>
3521 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3523 * src/gram.c (ritem_longest_rhs): Likewise.
3524 * src/reduce.c (nonterminals_reduce): Likewise.
3525 * src/print_graph.c (print_graph): Likewise.
3526 * src/output.c (output_rule_data): Likewise.
3527 * src/nullable.c (set_nullable): Likewise.
3529 2001-12-29 Akim Demaille <akim@epita.fr>
3531 * src/output.c: Comment changes.
3533 2001-12-27 Paul Eggert <eggert@twinsun.com>
3535 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3536 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3537 Sparc, as they were causing more porting problems than the
3538 (minor) performance improvement was worth.
3540 Also, catch up with 1.31's YYSTD.
3542 2001-12-27 Akim Demaille <akim@epita.fr>
3544 * src/output.c (output_gram): Rely on nritems, not the
3545 0-sentinel. See below.
3546 Use -1 as separator, not 0.
3547 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3548 Rely on -1 as separator in yyrhs, instead of 0.
3549 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3550 twice `Now at end of input', therefore there are two lines less to
3553 2001-12-27 Akim Demaille <akim@epita.fr>
3555 * tests/regression.at (Unresolved SR Conflicts):
3556 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3559 2001-12-27 Akim Demaille <akim@epita.fr>
3561 * src/LR0.c (new_state): Recognize the final state by the fact it
3562 is reached by eoftoken.
3563 (insert_start_shifting_state, insert_eof_shifting_state)
3564 (insert_accepting_state, augment_automaton): Remove, since now
3565 these states are automatically computed from the initial state.
3566 (generate_states): Adjust.
3567 * src/print.c: When reporting a rule number to the user, substract
3568 1, so that the axiom rule is rule 0, and the first user rule is 1.
3569 * src/reduce.c: Likewise.
3570 * src/print_graph.c (print_core): For the time being, just as for
3571 the report, depend upon --trace-flags to dump the full set of
3573 * src/reader.c (readgram): Once the grammar read, insert the rule
3574 0: `$axiom: START-SYMBOL $'.
3575 * tests/set.at: Adjust: rule 0 is now displayed, and since the
3576 number of the states has changed (the final state is no longer
3577 necessarily the last), catch up.
3579 2001-12-27 Akim Demaille <akim@epita.fr>
3581 Try to make the use of the eoftoken valid. Given that its value
3582 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3583 is used instead of > 0 where appropriate, (ii), depend upon nritems
3584 instead of the 0-sentinel.
3586 * src/gram.h, src/gram.c (nritems): New.
3587 Expected to be duplication of nitems, but for the time being...
3588 * src/reader.c (packgram): Assert nritems and nitems are equal.
3589 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3590 * src/closure.c (print_closure, print_fderives): Likewise.
3591 * src/gram.c (ritem_print): Likewise.
3592 * src/print.c (print_core, print_grammar): Likewise.
3593 * src/print_graph.c: Likewise.
3595 2001-12-27 Akim Demaille <akim@epita.fr>
3597 * src/main.c (main): If there are complains after grammar
3598 reductions, then output the report anyway if requested, then die.
3599 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3600 * src/reader.c (eoftoken): New.
3601 (parse_token_decl): If the token being defined has value `0', it
3603 (packsymbols): No longer hack `tags' to insert `$' by hand.
3604 Be sure to preserve the value of the eoftoken.
3605 (reader): Make sure eoftoken is defined.
3606 Initialize nsyms to 0: now eoftoken is created just like the others.
3607 * src/print.c (print_grammar): Don't special case the eof token.
3608 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3609 lie anyway, albeit pleasant.
3610 * tests/calc.at: Exercise error messages with eoftoken.
3611 Change the grammar so that empty input is invalid.
3612 Adjust expectations.
3613 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3615 2001-12-27 Akim Demaille <akim@epita.fr>
3617 * configure.in: Check the protos of strchr ans strspn.
3618 Replace strchr if needed.
3619 * src/system.h: Provide the protos of strchr, strspn and memchr if
3621 * lib/strchr.c: New.
3622 * src/reader.c (symbols_save): Use strchr.
3624 2001-12-27 Akim Demaille <akim@epita.fr>
3626 * src/print.c, src/print_graph.c (escape): New.
3627 Use it to quote the TAGS outputs.
3628 * src/print_graph.c (print_state): Now errors are in red, and
3629 reductions in green.
3630 Prefer high to wide: output the state number on a line of its own.
3632 2001-12-27 Akim Demaille <akim@epita.fr>
3634 * src/state.h, src/state.c (reductions_new): New.

3657 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3658 * src/print.c: here.
3659 (lookaheadset, shiftset): New, used as additional storage by
3661 (print_results): Adjust.
3662 (print_shifts, print_gotos, print_errs): New, extracted from...
3663 (print_actions): here.
3664 * src/print_graph.c (print_actions): Remove dead code.
3666 2001-12-27 Akim Demaille <akim@epita.fr>
3668 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3671 2001-12-27 Akim Demaille <akim@epita.fr>
3673 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.

3685 2001-12-27 Akim Demaille <akim@epita.fr>
3687 * src/files.c, src/files.h (guard_obstack): Remove.
3688 * src/output.c (output): Adjust.
3689 * src/reader.c (parse_braces): New, factoring...
3690 (copy_action, copy_guard): these two which are renamed as...
3691 (parse_action, parse_guard): these.
3692 As a voluntary consequence, using braces around guards is now
3695 2001-12-27 Akim Demaille <akim@epita.fr>
3697 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3698 * src/reader.c (symbol_list): `guard' and `guard_line' are new
3700 (symbol_list_new): Adjust.
3701 (copy_action): action_line is the first line, not the last.
3702 (copy_guard): Just as for actions, store the `action' only, not
3703 the switch/case/break flesh.
3704 Don't parse the user action that might follow the guard, let...
3705 (readgram): do it, i.e., now, there can be an action after a
3707 In other words the guard is just explicitly optional.
3709 * src/output.c (guards_output): New.
3710 (output_parser): Call it when needed.
3711 (output): Also free the guard and attrs obstacks.
3712 * src/files.c, src/files.h (obstack_save): Remove.
3713 (output_files): Remove.
3714 As a result, if one needs the former `.act' file, using an
3715 appropriate skeleton which requires actions and guards is now
3717 * src/main.c (main): Adjust.
3718 * tests/semantic.at: New.
3719 * tests/regression.at: Use `input.y' as input file name.
3720 Avoid 8+3 problems by requiring input.c when the test needs the

3725 * src/reader.c (symbol_list_new): Be sure to initialize all the

3733 * src/lalr.c (nLA): New.
3734 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it

3737 2001-12-27 Akim Demaille <akim@epita.fr>
3739 * src/output.c (action_row, token_actions): Use a state_t instead
3740 of a integer, and nlookaheads instead of the following state's

3745 * src/conflicts.c (log_resolution, flush_shift)
3746 (resolve_sr_conflict, set_conflicts, solve_conflicts)
3747 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3748 (conflicts_print, print_reductions): Use a state_t instead of an
3749 integer when referring to a state.
3750 As much as possible, depend upon nlookaheads, instead of the
3751 `lookaheadsp' member of the following state (since lookaheads of
3752 successive states are successive, the difference between state n + 1
3753 and n served as the number of lookaheads for state n).
3754 * src/lalr.c (add_lookback_edge): Likewise.
3755 * src/print.c (print_core, print_actions, print_state)
3756 (print_results): Likewise.

3763 * src/bison.hairy: Formatting/comment changes.
3765 Remove `register' indications.
3766 Add plenty of `static'.

3770 * src/output.c (prepare): Drop the muscle `ntbase' which
3772 * src/bison.simple: Formatting/comment changes.
3773 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3774 is an undocumented synonym.
3776 2001-12-22 Akim Demaille <akim@epita.fr>
3778 * src/output.c (output_table_data): Change the prototype to use
3779 `int' for array ranges: some invocations do pass an int, not a
3781 Reported by Wayne Green.
3783 2001-12-22 Akim Demaille <akim@epita.fr>
3785 Some actions of web2c.y are improperly triggered.
3786 Reported by Mike Castle.
3788 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.

3791 (Web2c Actions): New.
3793 2001-12-22 Akim Demaille <akim@epita.fr>
3795 Reductions in web2c.y are improperly reported.
3796 Reported by Mike Castle.
3798 * src/conflicts.c (print_reductions): Fix.
3799 * tests/regression.at (Web2c): New.
3801 2001-12-18 Akim Demaille <akim@epita.fr>
3803 Some host fail on `assert (!"foo")', which expands to
3804 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3805 Reported by Nelson Beebee.
3807 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3808 `#define it_succeeded 0' and `assert (it_succeeded)'.
3810 2001-12-17 Marc Autret <autret_m@epita.fr>
3812 * src/bison.simple: Don't hard code the skeleton line and filename.
3813 * src/output.c (output_parser): Rename 'line' as 'output_line'.
3814 New line counter 'skeleton_line' (skeleton-line muscle).
3816 2001-12-17 Paul Eggert <eggert@twinsun.com>
3818 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3819 YYDEBUG must be defined to a nonzero value.
3821 * src/bison.simple (yytname): Do not assume that the user defines
3822 YYDEBUG to a properly parenthesized expression.
3824 2001-12-17 Akim Demaille <akim@epita.fr>
3826 * src/state.h (state_t): Rename lookaheads as lookaheadsp.

3836 * src/main.c (main): Don't open/close files, nor invoke lex_free,
3838 * src/reader.c (reader): Do it.
3840 2001-12-17 Akim Demaille <akim@epita.fr>
3842 * src/conflicts.c (print_reductions): Formatting changes.
3844 2001-12-17 Akim Demaille <akim@epita.fr>
3846 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
3847 (flush_reduce): New.
3848 (resolve_sr_conflict): Adjust.
3850 2001-12-17 Akim Demaille <akim@epita.fr>
3852 * src/output.c (output_obstack): Be static and rename as...
3853 (format_obstack): this, to avoid any confusion with files.c's
3855 * src/reader.h (muscle_obstack): Move to...
3856 * src/output.h: here, since it's defined in output.c.
3858 2001-12-17 Akim Demaille <akim@epita.fr>
3860 * src/output.c (action_row, save_column, default_goto)
3861 (sort_actions, matching_state, pack_vector): Better variable
3864 2001-12-17 Akim Demaille <akim@epita.fr>
3866 * src/output.c: Various formatting changes.
3868 2001-12-17 Akim Demaille <akim@epita.fr>
3870 * src/files.c (output_files): Free the output_obstack.
3871 * src/main.c (main): Call print and print_graph conditionally.
3872 * src/print.c (print): Work unconditionally.
3873 * src/print_graph.c (print_graph): Work unconditionally.
3874 * src/conflicts.c (log_resolution): Output only if verbose_flag.
3876 2001-12-16 Marc Autret <autret_m@epita.fr>
3878 * src/output.c (actions_output): Fix. When we use %no-lines,
3879 there is one less line per action.
3881 2001-12-16 Marc Autret <autret_m@epita.fr>
3883 * src/bison.simple: Remove a useless #line directive.
3884 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3885 * src/output.c (get_lines_number): New.
3886 (output_parser): Adjust, now takes care about the lines of a
3889 (actions_output): Computes the number of lines taken by actions.
3890 (output_master_parser): Insert new skeleton which is the name of
3891 the output parser file name.
3893 2001-12-15 Marc Autret <autret_m@epita.fr>
3895 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
3897 2001-12-15 Marc Autret <autret_m@epita.fr>
3899 * src/output.c (output_gram): Keep track of the hairy one.
3901 2001-12-15 Akim Demaille <akim@epita.fr>
3903 Make `make distcheck' work.
3905 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3906 system.h which uses libgettext.h.
3908 2001-12-15 Akim Demaille <akim@epita.fr>
3910 * src/nullable.c (set_nullable): Useless rules must be skipped,
3911 otherwise, since we range over their symbols, we might look at a
3912 nonterminal which no longer ``exists'', i.e., it is not counted in
3913 `nvars', hence we overflow our arrays.
3915 2001-12-15 Akim Demaille <akim@epita.fr>
3917 The header can also be produced directly, without any obstack!
3920 * src/files.c, src/files.h (defines_obstack): Remove.
3921 (compute_header_macro): Global.
3922 (defines_obstack_save): Remove.
3923 * src/reader.c (parse_union_decl): No longer output to
3924 defines_obstack: its content can be found in the `stype' muscle
3926 (output_token_translations): Merge into...
3927 (symbols_output): this.
3929 (symbols_save): this.
3931 * src/output.c (header_output): New.
3934 2001-12-15 Akim Demaille <akim@epita.fr>
3936 * src/reader.c (parse_union_decl): Instead of handling two obstack
3937 simultaneously, use one to define the `stype' muscle, and use the
3938 value of the latter to fill defines_obstack.
3939 (copy_comment): Remove.
3940 (copy_comment2): Work for a single obstack.
3942 (copy_comment): this.
3944 2001-12-15 Akim Demaille <akim@epita.fr>
3946 * src/lex.c, src/lex.h (xgetc): No longer static.
3947 * src/reader.c (parse_union_decl): Revamp.
3949 2001-12-15 Akim Demaille <akim@epita.fr>
3951 Still making progress in separating Bison into (i) input, (ii)
3952 process, (iii) output: now we can directly output the parser file
3953 without using table_obstack at all.
3955 * src/files.c, src/files.h (table_obstack): Bye bye.
3956 (parser_file_name): New.
3957 * src/files.c (compute_output_file_names): Compute it.
3958 * src/output.c (actions_output, output_parser)
3959 (output_master_parser): To a file instead of an obstack.
3961 2001-12-15 Akim Demaille <akim@epita.fr>
3963 Attach actions to rules, instead of pre-outputting them to
3966 * src/gram.h (rule_t): action and action_line are new members.
3967 * src/reader.c (symbol_list): Likewise.
3968 (copy_action): Save the actions within the rule.
3969 (packgram): Save them in rule_table.
3970 * src/output.c (actions_output): New.
3971 (output_parser): Use it on `%%actions'.
3972 (output_rule_data): Don't free rule_table.
3974 (prepare): Don't save the `action' muscle.
3975 * src/bison.simple: s/%%action/%%actions/.
3977 2001-12-15 Akim Demaille <akim@epita.fr>
3979 * src/reader.c (copy_action): When --yacc, don't append a `;'
3980 to the user action: let it fail if lacking.
3981 Suggested by Arnold Robbins and Tom Tromey.
3983 2001-12-14 Akim Demaille <akim@epita.fr>
3985 * src/lex.c (literalchar): Simply return the char you decoded, non
3986 longer mess around with obstacks and int pointers.
3989 2001-12-14 Akim Demaille <akim@epita.fr>
3991 * src/lex.c (literalchar): Don't escape the special characters,
3992 just decode them, and keep them as char (before, eol was output as
3993 the 2 char string `\n' etc.).
3994 * src/output.c (output_rule_data): Use quotearg to output the
3997 2001-12-13 Paul Eggert <eggert@twinsun.com>
3999 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
4000 Do not infringe on the global user namespace when using C++.
4001 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
4002 All uses of `fprintf' and `stderr' changed.
4004 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
4006 2001-12-13 Akim Demaille <akim@epita.fr>
4008 The computation of nullable is broken: it doesn't handle empty
4011 * tests/torture.at (GNU AWK Grammar): New.
4012 * tests/sets.at (Nullable): New.
4013 * src/nullable.c (set_nullable): Instead of blindly looping over
4014 `ritems', loop over the rules, and then over their rhs's.
4016 Work around Autotest bugs.
4018 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
4019 frame, because Autotest understand lines starting with a `+' as
4020 traces from the shell. Then, they are not processed properly.
4021 Admittedly an Autotest bug, but we don't have time to wait for
4022 Autotest to catch up.
4023 * tests/regression.at (Broken Closure): Adjust to the new table
4026 * tests/sets.at: here.
4028 2001-12-13 Akim Demaille <akim@epita.fr>
4030 * src/closure.c (closure): Use nrules instead of playing tricks
4033 2001-12-13 Akim Demaille <akim@epita.fr>
4035 * src/print.c (print_actions): Output the handling of `$' as the
4036 traces do: shifting the token EOF. Before EOF was treated as a
4038 * tests/regression.at: Adjust some tests.
4039 * src/print_graph.c (print_core): Complete the set of items via
4040 closure. The next-to-final and final states are still unsatisfying,
4041 but that's to be addressed elsewhere.
4042 No longer output the rule numbers, but do output the state number.
4043 A single loop for the shifts + gotos is enough, but picked a
4044 distinct color for each.
4045 (print_graph): Initialize and finalize closure.
4047 2001-12-13 Akim Demaille <akim@epita.fr>
4049 * src/reader.c (readgram): Remove dead code, an strip useless
4051 (get_type): Remove, unused.
4053 2001-12-12 Akim Demaille <akim@epita.fr>
4055 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
4056 on that of lib/error.c.
4058 2001-12-12 Akim Demaille <akim@epita.fr>
4060 Some hosts don't like `/' in includes.
4062 * src/system.h: Include libgettext.h without qualifying the path.
4063 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
4066 2001-12-11 Marc Autret <autret_m@epita.fr>
4068 * src/output.c (output_parser): Remove useless muscle.
4070 2001-12-11 Marc Autret <autret_m@epita.fr>
4072 * src/bison.simple: Remove #line just before %%epilogue. It
4073 is now handled in ...
4074 * src/reader.c (read_additionnal_code): Add the output of a
4075 #line for the epilogue.
4077 2001-12-10 Marc Autret <autret_m@epita.fr>
4079 * src/reader.c (copy_definition): Re-use CPP-outed code which
4080 replace precedent remove.
4081 * src/bison.simple: Remove #line before %%prologue because
4082 %%input-line is wrong at this time.
4084 2001-12-10 Marc Autret <autret_m@epita.fr>
4086 * src/reader.c (symbols_output): Clean up.
4087 * src/output.c (output_gram, output): Clean up.
4089 2001-12-10 Akim Demaille <akim@epita.fr>
4091 * src/lalr.c (initialize_lookaheads): New. Extracted from...
4092 * src/LR0.c (set_state_table): here.
4093 * src/lalr.c (lalr): Call it.
4095 2001-12-10 Akim Demaille <akim@epita.fr>
4097 * src/state.h (shifts): Remove the `number' member: shifts are
4098 attached to state, hence no longer need to be labelled with a
4101 2001-12-10 Akim Demaille <akim@epita.fr>
4103 Now that states have a complete set of members, the linked list of
4104 shifts is useless: just fill directly the state's shifts member.
4106 * src/state.h (shifts): Remove the `next' member.
4107 * src/LR0.c (first_state, last_state): Remove.
4109 (augment_automaton): Don't look for the shifts that must be added
4110 a shift on EOF: it is those of the state we looked for! But now,
4111 since shifts are attached, it is no longer needed to looking
4112 merely by its id: its number.
4114 2001-12-10 Akim Demaille <akim@epita.fr>
4116 * src/LR0.c (augment_automaton): Better variable locality.
4117 Remove an impossible branch: if there is a state corresponding to
4118 the start symbol being shifted, then there is shift for the start
4119 symbol from the initial state.
4121 2001-12-10 Akim Demaille <akim@epita.fr>
4123 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
4124 only when appropriate: when insert_start_shifting_state' is not
4126 * tests/regression.at (Rule Line Numbers): Adjust.
4128 2001-12-10 Akim Demaille <akim@epita.fr>
4130 * src/LR0.c (augment_automaton): Now that all states have shifts,
4131 merge the two cases addition shifts to the initial state.
4133 2001-12-10 Akim Demaille <akim@epita.fr>
4135 * src/lalr.c (set_state_table): Move to...
4137 * src/lalr.c (lalr): Don't call it...
4138 * src/LR0.c (generate_states): do it.
4139 * src/LR0.h (first_state): Remove, only the table is used.
4141 2001-12-10 Akim Demaille <akim@epita.fr>
4143 * src/LR0.h (first_shift, first_reduction): Remove.
4144 * src/lalr.c: Don't use first_shift: find shifts through the
4147 2001-12-10 Akim Demaille <akim@epita.fr>
4149 * src/LR0.c: Attach shifts to states as soon as they are
4151 * src/lalr.c (set_state_table): Instead of assigning shifts to
4152 state, just assert that the mapping was properly done.
4154 2001-12-10 Akim Demaille <akim@epita.fr>
4156 * src/LR0.c (insert_start_shift): Rename as...
4157 (insert_start_shifting_state): this.
4158 (insert_eof_shifting_state, insert_accepting_state): New.
4159 (augment_automaton): Adjust.
4160 Better locality of the variables.
4161 When looking if the start_symbol is shifted from the initial
4162 state, using `while (... symbol != start_symbol ...)' sounds
4163 better than `while (... symbol < start_symbol ...)': If fail
4164 to see how the order between symbols could be relevant!
4166 2001-12-10 Akim Demaille <akim@epita.fr>
4168 * src/getargs.h: Don't declare `spec_name_prefix' and
4169 `spec_file_prefix', declared by src/files.h.
4170 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
4171 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
4172 * src/output.c (prepare): Adjust.
4173 * src/reader.c (symbols_output): Likewise.

4176 2001-12-10 Akim Demaille <akim@epita.fr>
4178 * src/muscle_tab.c (muscle_init): NULL is a better default than
4181 2001-12-10 Akim Demaille <akim@epita.fr>
4183 * src/reader.c (reader): Calling symbols_output once is enough.
4185 2001-12-10 Akim Demaille <akim@epita.fr>
4187 Now that states have a complete set of members, the linked list of
4188 reductions is useless: just fill directly the state's reductions
4191 * src/state.h (struct reductions): Remove member `number' and
4193 * src/LR0.c (first_reduction, last_reduction): Remove.
4194 (save_reductions): Don't link the new reductions, store them in
4196 * src/lalr.c (set_state_table): No need to attach reductions to
4197 states, it's already done.
4198 * src/output.c (output_actions): No longer free the shifts, then
4199 the reductions, then the states: free all the states and their
4202 2001-12-10 Akim Demaille <akim@epita.fr>
4204 * src/options.c (OPTN, DRTV, BOTH): New.
4205 (option_table): Use them.
4207 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
4208 the job of system.h.
4209 * src/options.c: Don't include stdio.h and xalloc.h for the same
4212 2001-12-10 Akim Demaille <akim@epita.fr>
4214 * src/output.c (output, prepare): Make sure the values of the
4215 muscles `action' and `prologue' are 0-terminated.
4217 2001-12-10 Akim Demaille <akim@epita.fr>
4219 Clean up GCC warnings.
4221 * src/reader.c (copy_action): `buf' is not used.

4224 * src/options.h (create_long_option_table): Have a real prototype.
4225 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)

4227 Adjust casts to preserve the const.
4229 2001-12-10 Akim Demaille <akim@epita.fr>
4231 * configure.in: Require 2.52g.
4232 M4 is not needed, but AUTOM4TE is.
4234 * tests/Makefile.am: Adjust.
4236 2001-12-10 Akim Demaille <akim@epita.fr>
4238 One structure for states is enough, even though theoretically
4239 there are LR(0) states and LALR(1) states.
4241 * src/lalr.h (state_t): Remove.
4242 (state_table): Be state_t **, not state_t *.
4243 * src/state.h (core, CORE_ALLOC): Rename as...
4244 (state_t, STATE_ALLOC): this.
4245 Add the LALR(1) members: shifts, reductions, errs.
4246 * src/LR0.c (state_table): Rename as...
4247 (state_hash): this, to avoid name clashes with the global
4249 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4250 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
4252 2001-12-10 Akim Demaille <akim@epita.fr>
4254 Bison dumps core on bash.y.
4255 Reported by Pascal Bart.
4257 * src/warshall.c (bitmatrix_print): New.
4259 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4260 j must be the outer loop.
4261 * tests/regression.at (Broken Closure): New.
4263 2001-12-05 Akim Demaille <akim@epita.fr>
4265 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4267 Reported by Peter Hámorský.

4272 (resolve_sr_conflict): Adjust.
4273 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4275 (state_t.reductions, state_t.shifts): this.
4277 2001-12-05 Akim Demaille <akim@epita.fr>
4279 * src/reduce.c (reduce_grammar_tables): No longer disable the
4280 removal of useless rules via CPP but via `if (0)', so that the
4281 compiler still check the code is valid.
4282 For instance, it should have noticed `rline' no longer exists: use
4283 the `line' member of rule_t.
4284 * src/gram.c (dummy, rline): Remove, unused.
4286 2001-12-05 Akim Demaille <akim@epita.fr>
4288 * src/output.c (pack_vector): Use assert, not berror.
4289 * src/main.c (berror): Remove, unused.
4291 2001-12-05 Akim Demaille <akim@epita.fr>
4293 New experimental feature: if --verbose --trace output all the
4294 items of a state, not only its kernel.
4296 * src/print.c (print_core): If `trace_flag', then invoke closure
4297 before outputting the items of the state (print_core is no longer
4298 a correct name them).
4299 (print_results): Invoke new_closure/free_closure if needed.
4301 2001-12-05 Akim Demaille <akim@epita.fr>
4303 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4304 * src/closure.c, src/closure.h (itemsetsize): Rename as...
4305 (nitemset): for consistency with the rest of the project.
4307 2001-12-05 Akim Demaille <akim@epita.fr>
4309 * src/closure.c (print_closure): Improve.
4310 (closure): Use it for printing input and output.
4312 2001-12-05 Akim Demaille <akim@epita.fr>
4314 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4315 indexed by nonterminals.
4317 2001-12-05 Akim Demaille <akim@epita.fr>
4319 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of

4337 * src/output.c (action_row): De-obfuscate
4338 using the good o' techniques: arrays not pointers, variable
4339 locality, BITISSET, RESETBIT etc.
4341 2001-12-05 Akim Demaille <akim@epita.fr>
4343 Pessimize the code to simplify it: from now on, all the states
4344 have a valid SHIFTS, which NSHIFTS is possibly 0.
4346 * src/LR0.c (shifts_new): Be global and move to..
4347 * src/state.c, src/state.h: here.
4348 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4349 * src/print_graph: Adjust.
4351 2001-12-05 Akim Demaille <akim@epita.fr>
4353 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4354 * src/conflicts.c: Use it.
4355 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4356 incorrectly ``simplified''.
4358 2001-12-05 Akim Demaille <akim@epita.fr>
4360 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4361 using the good o' techniques: arrays not pointers, variable

4366 * src/state.h (SHIFT_SYMBOL): New.
4367 * src/conflicts.c: Use it to deobfuscate.

4371 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4372 (print_reductions): De-obfuscate using the good o' techniques:
4373 arrays not pointers, variable locality, BITISSET.

4409 (transpose): Use it.
4410 Use arrays instead of pointers.
4412 2001-12-05 Akim Demaille <akim@epita.fr>
4414 * src/lalr.c (maxrhs): Move to...
4415 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4416 * src/lalr.c (build_relations): Adjust.
4418 2001-12-05 Akim Demaille <akim@epita.fr>
4420 * src/lalr.c (transpose): Free the memory allocated to the
4421 argument, as it is replaced by the results by the unique caller.
4422 (build_relations): Merely invoke transpose: it handles the memory
4424 Improve variable locality.
4425 Avoid variables used as mere abbreviations.
4426 (compute_lookaheads): Use arrays instead of pointers.
4428 2001-12-05 Akim Demaille <akim@epita.fr>
4430 * src/lalr.c (initialize_F): Improve variable locality.

4435 * src/derives.c (print_derives): Display the ruleno.
4436 * src/lalr.c (initialize_F, transpose): Better variable locality
4437 to improve readability.
4438 Avoid variables used as mere abbreviations.
4440 2001-12-05 Akim Demaille <akim@epita.fr>
4442 * src/lalr.c (traverse): Use arrays instead of pointers.
4444 2001-12-05 Akim Demaille <akim@epita.fr>
4446 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4447 the handling of squeue.
4448 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4450 2001-12-05 Akim Demaille <akim@epita.fr>
4452 Because useless nonterminals are now kept alive (instead of being
4453 `destroyed'), we now sometimes examine them, and store information
4454 related to them. Hence we need to know their number, and adjust
4457 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4459 * src/LR0.c (allocate_itemsets): The memory allocated to
4460 `symbol_count' was used for two different purpose: once to count
4461 the number of occurrences of each symbol, and later reassigned to
4462 `shift_symbol', containing the symbol that can be shifted from a
4464 Deobfuscate, i.e., allocate, use and free `symbol_count' here
4466 (new_itemsets): Allocate `shift_symbol' here.
4467 (allocate_itemsets): symbol_count includes useless nonterminals.
4469 (free_storage): Use `free', not `XFREE', for pointers that cannot
4472 2001-12-05 Akim Demaille <akim@epita.fr>
4474 * src/nullable.c (set_nullable): Deobfuscate the handling of
4476 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4478 2001-12-05 Akim Demaille <akim@epita.fr>
4480 * src/gram.c, src/gram.h (ritem_print): New.
4481 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4482 (This useless function was defined only to work around VMS linkers
4483 that can't handle compilation units with variables only).
4484 * src/reduce.c (dump_grammar): Use it to trace the construction of
4487 2001-12-04 Paul Eggert <eggert@twinsun.com>
4489 * src/bison.simple (union yyalloc): Change member names
4490 to be the same as the stack names.
4491 (yyparse): yyptr is now union yyalloc *, not char *.
4492 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
4493 and may generate better code on some machines.
4494 (yystpcpy): Use prototype if __STDC__ is defined, not just
4495 if __cplusplus is defined.
4497 2001-11-30 Akim Demaille <akim@epita.fr>
4499 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4500 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4501 Gettext doesn't compile cleanly, and dies with -Werror.
4502 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4503 Include WARNING_CFLAGS here.
4504 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4505 before being defined.

4509 * lib/quotearg.h (quotearg_n, quotearg_n_style):
4510 First arg is int, not unsigned.
4511 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4512 (SIZE_MAX, UINT_MAX): New macros.
4513 (quotearg_n_options): Abort if N is negative.
4514 Avoid overflow check on hosts where size_t is 64 bits and int
4515 is 32 bits, as overflow is impossible there.
4516 Fix off-by-one typo that caused unnecessary reallocation.
4518 2001-11-29 Paul Eggert <eggert@twinsun.com>
4520 Name space cleanup in generated parser.
4522 * doc/bison.texinfo (Bison Parser): Discuss system headers
4523 and their effect on the user name space.
4526 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4527 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4528 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4530 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
4531 on user names when possible.
4533 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4534 Simplify test for whather <alloca.h> exists.
4536 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4538 (<stdio.h>): Include if YYDEBUG.
4540 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
4541 ! defined (yyoverflow) && ! defined (yymemcpy).
4543 (yymemcpy, yyparse): Rename local variables as needed so that
4544 they all begin with 'yy'.
4546 (yystrlen, yystpcpy): New functions.
4548 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4551 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
4552 instead of relying on string.h functions. Use YYSTACK_ALLOC
4553 and YYSTACK_FREE instead of malloc and free.
4555 2001-11-30 Akim Demaille <akim@epita.fr>
4557 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
4558 before their first uses.
4559 (YYBISON, YYPURE): Move to the top of the output.
4561 2001-11-30 Akim Demaille <akim@epita.fr>
4563 * tests/reduce.at (Useless Nonterminals): Fix.
4565 2001-11-30 Akim Demaille <akim@epita.fr>
4567 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4568 if body instead of `;' to pacify GCC's warnings.
4570 2001-11-30 Akim Demaille <akim@epita.fr>
4572 Instead of mapping the LHS of unused rules to -1, keep the LHS
4573 valid, but flag the rules as invalid.
4575 * src/gram.h (rule_t): `useful' is a new member.
4576 * src/print.c (print_grammar): Adjust.
4577 * src/derives.c (set_derives): Likewise.
4578 * src/reader.c (packgram, reduce_output): Likewise.
4579 * src/reduce.c (reduce_grammar_tables): Likewise.
4580 * tests/reduce.at (Underivable Rules, Useless Rules): New.
4582 2001-11-30 Akim Demaille <akim@epita.fr>
4584 * src/reduce.c (reduce_output): Formatting changes.
4585 * src/print.c (print_results, print_grammar): Likewise.
4586 * tests/regression.at (Rule Line Numbers)
4587 (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
4589 2001-11-30 Akim Demaille <akim@epita.fr>
4591 * src/reduce.c (nonterminals_reduce): Instead of throwing away
4592 useless nonterminals, move them at the end of the symbol arrays.
4593 (reduce_output): Adjust.
4594 * tests/reduce.at (Useless Nonterminals): Adjust.
4596 2001-11-30 Akim Demaille <akim@epita.fr>
4598 * src/reduce.c: Various comment/formatting changes.
4599 (nonterminals_reduce): New, extracted from...

4605 * src/bison.simple (YYSTACK_REALLOC): Remove.
4606 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4607 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4609 (union yyalloc): New type.
4610 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4611 an arbitrary restriction on hosts where size_t is wider than int.
4613 (yyparse): Don't dump core if alloca or malloc fails; instead, report
4614 a parser stack overflow. Allocate just one block of memory for all
4615 three stacks, instead of allocating three blocks; this typically is
4616 faster and reduces fragmentation.
4618 Do not limit the number of items in the stack to a value that fits
4619 in 'int', as this is an arbitrary limit on hosts with 64-bit
4620 size_t and 32-bit int.
4622 2001-11-29 Marc Autret <autret_m@epita.fr>
4624 * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
4625 of defining YYERROR_VERBOSE.

4635 2001-11-28 Marc Autret <autret_m@epita.fr>
4637 * src/output.h: And put its extern declaration here.
4638 * src/output.c (error_verbose): Define here.
4639 (prepare): Echo name modification.
4640 * src/getargs.h: Clean its extern declaration.
4641 * src/getargs.c (error_verbose_flag): Remove.
4642 (getargs): Remove case 'e'.
4643 * src/options.c (option_table): 'error-verbose' is now seen as simple
4647 * src/reader.c (read_declarations): Remove case tok_include.
4648 (parse_include_decl): Remove.
4649 * src/lex.h (token_t): Remove tok_include.

4670 2001-11-28 Akim Demaille <akim@epita.fr>
4672 * src/closure.c (closure): `b' and `ruleno' denote the same value:
4675 2001-11-28 Akim Demaille <akim@epita.fr>
4677 * src/closure.c (closure): Instead of looping over word in array
4678 then bits in words, loop over bits in array.
4680 2001-11-28 Akim Demaille <akim@epita.fr>
4682 * src/closure.c (closure): No longer optimize the special case
4683 where all the bits of `ruleset[r]' are set to 0, to make the code
4686 2001-11-28 Akim Demaille <akim@epita.fr>
4688 * src/closure.c (closure): `r' and `c' are new variables, used to
4689 de-obfuscate accesses to RULESET and CORE.
4691 2001-11-28 Akim Demaille <akim@epita.fr>

6425 * src/conflicts.c (conflict_report): Be sure not to append to res
6426 between two calls, which could happen if both first sprintf were

6432 New, from fileutils 4.0.37.
6433 * configure.in: Require Autoconf 2.49c. I took some time before
6434 making this decision. This is the only way out for portability
6435 issues in Bison, it would mean way too much duplicate effort to
6436 import in Bison features implemented in 2.49c since 2.13.
6437 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

6478 * src/reader.c (read_declarations): Adjust.
6479 * src/files.c (open_files): Don't call `compute_base_names', don't

6483 * src/output.c (output_headers): Document the fact that this patch
6484 introduces a guaranteed SEGV for semantic parsers.

6561 * src/output.c (output_parser): Compute the `#line' lines when
6563 * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
6564 Suggested by Hans Aberg.
6566 2000-12-19 Akim Demaille <akim@epita.fr>

6622 prevents type checking.
6623 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6624 cast the value to (void *): assigning a `foo *' to a `void *'

6627 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6639 * tests/regression.m4 (%union and --defines): New test,
6640 demonstrating a current bug in the obstack implementation.

6704 (done): Rename as...
6705 (output_files): this.
6707 * src/main.c (main): Don't use `atexit' to register `done', since
6708 it no longer has to remove tmp files, just call `output_files'
6709 when there are no errors.
6711 2000-11-02 Akim Demaille <akim@epita.fr>
6713 * src/files.c [VMS]: No longer include `ssdef.h', no longer define
6714 `unlink': it's no longer used.
6715 * src/files.h: Formatting changes.

6783 (copy_comment, copy_definition, parse_union_decl, copy_action)
6784 (copy_guard): Adjust.
6786 2000-10-16 Akim Demaille <akim@epita.fr>

6812 2000-10-04 Akim Demaille <akim@epita.fr>
6814 When a literal string is used to define two different tokens,
6815 `bison -v' segfaults.
6816 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
6818 * tests/regression.m4: New file.
6819 Include the core of the sample provided by Piotr Gackiewicz.
6820 * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
6823 2000-10-04 Akim Demaille <akim@epita.fr>

6843 translation, move some `\n' out of the translated strings.
6845 2000-10-02 Akim Demaille <akim@epita.fr>
6847 The location tracking mechanism is precious for parse error
6848 messages. Nevertheless, it is enabled only when `@n' is used in
6849 the grammar, which is a different issue (you can use it in error
6850 message, but not in the grammar per se). Therefore, there should
6851 be another means to enable it.
6853 * src/getargs.c (getargs): Support `--locations'.
6855 * src/getargs.h (locationsflag): Export it.
6856 * src/lex.c (percent_table): Support `%locations'.

6864 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6865 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6866 In addition replace each `flag' with `_flag'.
6868 2000-10-02 Akim Demaille <akim@epita.fr>

6881 2000-10-02 Akim Demaille <akim@epita.fr>
6883 Test also `--verbose', `--defines' and `--name-prefix'. Testing
6884 the latter demonstrates a flaw in the handling of non debugging
6885 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6886 was used in order to simplify:
6902 unfortunately this leads to a CPP conflict when
6903 `--name-prefix=foo' is used since it produces `#define yydebug
6906 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6907 (YYDPRINTF): New macro.
6909 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6911 Also test `--verbose', `--defines' and `--name-prefix'.

6915 Improve the readability of the produced parsers.
6917 * src/bison.s1: Formatting changes.
6918 Improve the comment related to the `$' mark.
6919 (yydefault): Don't fall through to `yyresume': `goto' there.
6920 * src/output.c (output_parser): When the `$' is met, skip the end
6922 New variable, `number_of_dollar_signs', to check there's exactly
6923 one `$' in the parser skeleton.
6925 2000-10-02 Akim Demaille <akim@epita.fr>
6927 * lib/xstrdup.c: New file, from the fileutils.
6928 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6929 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6930 instead of strlen + xmalloc + strcpy.
6931 * src/symtab.c (copys): Remove, use xstrdup instead.
6933 2000-10-02 Akim Demaille <akim@epita.fr>
6935 * src/gram.h (associativity): New enum type which replaces the
6936 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6937 `right_assoc', `left_assoc' and `non_assoc'.
6938 Adjust all dependencies.

6943 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

6949 (yaccflag): for consistency and accuracy.
6950 Adjust dependencies.
6952 2000-10-02 Akim Demaille <akim@epita.fr>
6954 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6955 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6956 difficult and introduced a lot of core dump. It turns out that
6957 Bison used an implementation of `xmalloc' based on `calloc', and
6958 at various places it does depend upon the initialization to 0. I
6959 have not tried to isolate the pertinent places, and all the former
6960 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6961 someone should address this issue.
6963 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

7062 2000-10-02 Akim Demaille <akim@epita.fr>
7064 `user_toknums' is output as a `short[]' in `output.c', while it is
7065 defined as a `int[]' in `reader.c'. For consistency with the
7066 other output tables, `user_toknums' is now defined as a table of

7110 * src/system.h: Define PARAMS.
7111 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

7331 Change the handling of @s so that they behave exactly like $s.
7332 There is now a pseudo variable @$ (readble and writable), location
7333 of the lhs of the rule (by default ranging from the location of
7334 the first symbol of the rhs, to the location of the last symbol,
7335 or, if the rhs is empty, YYLLOC).
7337 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
7339 (yyparse): When providing a default semantic action, provide a
7340 default location action.
7341 (after the $): No longer change `*YYLSP', just stack YYLOC the
7342 same way you stack YYVAL.
7343 * src/reader.c (read_declarations): Use warns.
7344 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

7370 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7371 One `#if YYDEBUG' remains, since it uses variables which are
7372 defined only if `YYDEBUG != 0'.
7374 2000-03-16 Akim Demaille <akim@epita.fr>
7376 * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

7396 Bump to bison 1.28a, 1.29 has never been released.
7397 * acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
7398 handled via src/Makefile.am.

8098 way to specify the flags -n, -l, and -r. Also added hooks for
8099 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
8100 major changes to files.c.
