 206 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 207
 208         Remove the support for C++ namespace cleanliness; it was
 209         causing more problems than it was curing, since it didn't work
 210         properly on some nonstandard C++ compilers.  This can wait
 211         for a proper C++ parser.
 212
 213         * NEWS: Document this.
 214         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention

 230
 231         * src/output.c (output_rule_data): Don't output NULL, it might

 252
 253 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 254
 255         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 256         more consistent when naming methods and variables.  Put preprocessor
 257         directives around tables only needed for debugging.
 258
 259 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

 282         not expanded by m4.
 283
 284 2002-02-05  Akim Demaille  <akim@epita.fr>
 285
 286         * data/bison.c++: Adjust to the M4 back end.

 300         * src/output.c (actions_output, guards_output)
 301         (token_definitions_output): No longer keeps track of the output
 302         line number, hence remove the second argument.
 303         (guards_output): Check against the guard member of a rule, not the
 304         action member.
 305         Adjust callers.
 306         (output_skeleton): Don't look for the skeleton location, let m4 do
 307         that.
 308         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 309         file will be used.
 310         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 311         (prepare): Given that for the time being changesyntax is not
 312         usable in M4, rename the muscles using `-' to `_'.
 313         Define `defines_flag', `output_parser_name' and `output_header_name'.
 314         * src/output.h (actions_output, guards_output)

 316         * src/scan-skel.l: Instead of scanning the skeletons, it now

 318         * data/bison.simple: Adjust to be used by M4(sugar).
 319         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 320         to date.
 321         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 322         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 323         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 324         shamelessly stolen from CVS Autoconf.

 341
 342 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 343
 344         * src/bison.simple (YYSIZE_T): Do not define merely because
 345         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 346         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 347
 348 2002-01-27  Akim Demaille  <akim@epita.fr>
 349
 350         Fix `%nonassoc and eof'.
 351
 352         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 353         which were not properly copied!  Replace
 354         memcpy (res->errs, src->errs, src->nerrs);
 355         with
 356         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 357         !!!
 358         * tests/regression.at (%nonassoc and eof): Adjust to newest
 359         Autotest: `.' is not in the PATH.

 370         * tests/torture.at: Adjust to the newest Autotest which no longer
 371         forces `.' in the PATH.

 375         * tests/regression.at (%nonassoc and eof): New.
 376         Suggested by Robert Anisko.
 377
 378 2002-01-24  Akim Demaille  <akim@epita.fr>
 379
 380         Bison dumps core when trying to complain about broken input files.
 381         Reported by Cris van Pelt.
 382
 383         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 384         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 385         into...
 386         (Invalid inputs): Strengthen: exercise parse_percent_token.
 387
 388 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 389
 390         * src/Makefile.am: Add bison.c++.
 391         * src/bison.c++: New skeleton.
 392
 393 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 394
 395         * po/it.po: New.
 396
 397 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 398
 399         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 400
 401 2002-01-20  Marc Autret  <marc@gnu.org>
 402
 403         * src/files.c (compute_output_file_names): Fix
 404
 405 2002-01-20  Marc Autret  <marc@gnu.org>
 406
 407         * tests/output.at: New test.
 408         * src/files.c (compute_base_names): Don't map extensions when
 409         the YACC flag is set, use defaults.
 410         Reported by Evgeny Stambulchik.
 411
 412 2002-01-20  Marc Autret  <marc@gnu.org>
 413
 414         * src/system.h: Need to define __attribute__ away for non-GCC
 415         compilers as well (i.e. the vendor C compiler).
 416         Suggested by Albert Chin-A-Young.
 417
 418 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 419
 420         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 421         canonical definition.
 422         * src/system.h: Use the canonical definition for PARAMS (avoids
 423         a conflict with the macro from lib/hash.h).
 424
 425 2002-01-11  Akim Demaille  <akim@epita.fr>
 426
 427         * configure.in: Use AC_FUNC_STRNLEN.
 428         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 429
 430 2002-01-09  Akim Demaille  <akim@epita.fr>
 431
 432         * src/files.c, src/files.h (output_infix): New.
 433         (tab_extension): Remove.
 434         (compute_base_names): Compute the former, drop the latter.
 435         * src/output.c (prepare): Insert the muscles `output-infix', and
 436         `output-suffix'.
 437         * src/parse-skel.y (string, string.1): New.
 438         (section.header): Use it.
 439         (section.yacc): Remove.
 440         (prefix): Remove too.
 441         * src/scan-skel.l: Adjust.
 442         * src/bison.simple, src/bison.hairy: Adjust.
 443
 444 2002-01-09  Akim Demaille  <akim@epita.fr>
 445
 446         * configure.in (WERROR_CFLAGS): Compute it.
 447         * src/Makefile.am (CFLAGS): Pass it.
 448         * tests/atlocal.in (CFLAGS): Idem.
 449         * src/files.c: Fix a few warnings.
 450         (get_extension_index): Remove, unused.
 451
 452 2002-01-08  Akim Demaille  <akim@epita.fr>
 453
 454         * src/getargs.c (AS_FILE_NAME): New.
 455         (getargs): Use it to convert DOSish file names.
 456         * src/files.c (base_name): Rename as full_base_name to avoid
 457         clashes with `base_name ()'.
 458         (filename_split): New.
 459         (compute_base_names): N-th rewrite, using filename_split.
 460
 461 2002-01-08  Akim Demaille  <akim@epita.fr>
 462
 463         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 464         New, stolen from the Fileutils 4.1.
 465         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 466         * configure.in: Check for the presence of memrchr, and of its
 467         prototype.
 468
 469 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 470
 471         * lib/hash.h (__P): Added definition for this macro.
 472         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 473         BUILT_SOURCES, to ensure they are generated first.
 474         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 475         %error-verbose to allow bootstrapping with bison 1.30x.
 476
 477 2002-01-06  Akim Demaille  <akim@epita.fr>
 478
 479         * src/reader.c (parse_braces): Don't fetch the next char, the
 480         convention is to fetch on entry.
 481         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 482         'switch' without a following semicolon.
 483         * tests/regression.at (braces parsing): New.
 484
 485 2002-01-06  Akim Demaille  <akim@epita.fr>
 486
 487         Bison is dead wrong in its RR conflict reports.
 488
 489         * tests/torture.at (GNU Cim Grammar): New.
 490         * src/conflicts.c (count_rr_conflicts): Fix.
 491
 492 2002-01-06  Akim Demaille  <akim@epita.fr>
 493
 494         Creating package.m4 from configure.ac causes too many problems.
 495
 496         * tests/Makefile.am (package.m4): Create it by hand,
 497         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 498
 499 2002-01-06  Akim Demaille  <akim@epita.fr>
 500
 501         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 502         skeleton.h.
 503
 504 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 505
 506         * doc/bison.texinfo (Debugging):
 507         Remove YYSTDERR; it's no longer defined or used.
 508         Also, s/cstdio.h/cstdio/.
 509
 510 2002-01-03  Akim Demaille  <akim@epita.fr>
 511
 512         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 513
 514 2002-01-03  Akim Demaille  <akim@epita.fr>
 515
 516         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 517         tracing code to --trace, wait for a better --trace option, with
 518         args.
 519
 520 2002-01-03  Akim Demaille  <akim@epita.fr>
 521
 522         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 523         The ISO C++ standard is extremely clear about it: stderr is
 524         considered a macro, not a regular symbol (see table 94 `Header
 525         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 526         Therefore std:: does not apply to it.  It still does with fprintf.
 527         Also, s/cstdio.h/cstdio/.
 528
 529 2002-01-03  Akim Demaille  <akim@epita.fr>
 530
 531         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 532         for non system headers.
 533
 534 2002-01-02  Akim Demaille  <akim@epita.fr>
 535
 536         Equip the skeleton chain with location tracking, runtime trace,
 537         pure parser and scanner.
 538
 539         * src/parse-skel.y: Request a pure parser, locations, and prefix
 540         renaming.
 541         (%union): Having several members with the same type does not help
 542         type mismatches, simplify.
 543         (YYPRINT, yyprint): New.
 544         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 545         (skel_error): this.
 546         Handle locations.
 547         * src/scan-skel.l: Adjust to these changes.
 548         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 549         (LOCATION_PRINT, skel_control_t): New.
 550
 551 2001-12-30  Akim Demaille  <akim@epita.fr>
 552
 553         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 554         replace `gb' with BLANKS.
 555         * src/scan-skel.l: Adjust.
 556
 557 2001-12-30  Akim Demaille  <akim@epita.fr>
 558
 559         * src/system.h: We don't need nor want bcopy.
 560         Throw away MS-DOS crap: we don't need getpid.
 561         * configure.in: We don't need strndup.  It was even causing
 562         problems: because Flex includes the headers *before* us,
 563         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 564         not visible.
 565         * lib/xstrndup.c: New.
 566         * src/scan-skel.l: Use it.
 567         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 568         * src/parse-skel.y: Use %directives instead of #defines.
 569
 570 2001-12-30  Akim Demaille  <akim@epita.fr>
 571
 572         * src/skeleton.h: New.
 573         * src/output.c (output_parser, output_master_parser): Remove, dead
 574         code.
 575         * src/output.h (get_lines_number, actions_output, guards_output)
 576         (token_definitions_output): Prototype them.
 577         * src/parse-skel.y: Add the license notice.
 578         Include output.h and skeleton.h.
 579         (process_skeleton): Returns void, and takes a single parameter.
 580         * src/scan-skel.l: Add the license notice.
 581         Include skeleton.h.
 582         Don't use %option yylineno: it seems that then Flex imagines
 583         REJECT has been used, and therefore it won't reallocate its
 584         buffers (which makes no other sense to me than a bug).  It results
 585         in warnings for `unused: yy_flex_realloc'.
 586
 587 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 588
 589         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 590         (MUSCLE_INSERT_PREFIX): ...to there.
 591         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 592         (MUSCLE_INSERT_PREFIX): Move from here...
 593
 594         * src/bison.hairy: Add a section directive.  Put braces around muscle
 595         names.  This parser skeleton is still broken, but Bison should not
 596         choke on a bad muscle 'syntax'.
 597         * src/bison.simple: Add a section directive.  Put braces around muscle
 598         names.
 599
 600         * src/files.h (strsuffix, stringappend): Add declarations.
 601         (tab_extension): Add declaration.
 602         (short_base_name): Add declaration.
 603
 604         * src/files.c (strsuffix, stringappend): No longer static.  These
 605         functions are used in the skeleton parser.
 606         (tab_extension): New.
 607         (compute_base_names): Use the computations done in this function
 608         to guess if the generated parsers should have '.tab' in their
 609         names.
 610         (short_base_name): No longer static.
 611
 612         * src/output.c (output_skeleton): New.
 613         (output): Disable call to output_master_parser, and give a try to
 614         a new skeleton handling system.
 615         (guards_output, actions_output): No longer static.
 616         (token_definitions_output, get_lines_number): No longer static.
 617
 618         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 619
 620         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 621         parse-skel.y.
 622
 623         * src/parse-skel.y: New file.
 624         * src/scan-skel.l: New file.
 625
 626 2001-12-29  Akim Demaille  <akim@epita.fr>
 627
 628         %name-prefix is broken.
 629
 630         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 631         Adjust all dependencies.
 632         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 633         %name-prefix.
 634
 635         Renaming yylval but not yylloc is not consistent.  Now we do.
 636
 637         * src/bison.simple: Prefix yylloc if used.
 638         * doc/bison.texinfo (Decl Summary): Document that.
 639
 640 2001-12-29  Akim Demaille  <akim@epita.fr>
 641
 642         * doc/bison.texinfo: Promote `%long-directive' over
 643         `%long_directive'.
 644         Remove all references to fixed-output-files, yacc is enough.
 645
 646 2001-12-29  Akim Demaille  <akim@epita.fr>
 647
 648         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 649         user prologue.  These are defaults.
 650         * tests/actions.at (Mid-rule actions): Make sure the user can
 651         define YYDEBUG and YYERROR_VERBOSE.
 652
 653 2001-12-29  Akim Demaille  <akim@epita.fr>
 654
 655         * src/output.c (header_output): Don't forget to export YYLTYPE and
 656         yylloc.
 657         * tests/headers.at (export YYLTYPE): New, make sure it does.
 658         * tests/regression.at (%union and --defines, Invalid CPP headers):
 659         Move to...
 660         * tests/headers.at: here.
 661
 662 2001-12-29  Akim Demaille  <akim@epita.fr>
 663
 664         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 665
 666 2001-12-29  Akim Demaille  <akim@epita.fr>
 667
 668         * tests/actions.at (Mid-rule actions): Output on a single line
 669         instead of several.
 670
 671 2001-12-29  Akim Demaille  <akim@epita.fr>
 672
 673         * doc/bison.texinfo: Formatting changes.
 674
 675 2001-12-29  Akim Demaille  <akim@epita.fr>
 676
 677         Don't store the token defs in a muscle, just be ready to output it
 678         on command.  Now possible via `symbols'.  Fixes a memory leak.
 679
 680         * src/output.c (token_definitions_output): New.
 681         (output_parser, header_output): Use it.
 682         * src/reader.c (symbols_save): Remove.
 683
 684 2001-12-29  Akim Demaille  <akim@epita.fr>
 685
 686         * src/bison.simple: Do not provide a default for YYSTYPE and
 687         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 688         default.
 689
 690 2001-12-29  Akim Demaille  <akim@epita.fr>
 691
 692         Mid-rule actions are simply... ignored!
 693
 694         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 695         the empty-rule associated to the dummy symbol, not to the host
 696         rule.
 697         * tests/actions.at (Mid-rule actions): New.
 698
 699 2001-12-29  Akim Demaille  <akim@epita.fr>
 700
 701         Memory leak.
 702
 703         * src/reader.c (reader): Free grammar.
 704
 705 2001-12-29  Akim Demaille  <akim@epita.fr>
 706
 707         Memory leak.
 708
 709         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 710         since it allocates it for each state, although only one is needed.
 711         (allocate_storage): Do it here.
 712
 713 2001-12-29  Akim Demaille  <akim@epita.fr>
 714
 715         * src/options.h, src/options.c (create_long_option_table): Rename
 716         as...
 717         (long_option_table_new): this, with a clearer prototype.
 718         (percent_table): Remove, unused,
 719         * src/getargs.c (getargs): Adjust.
 720
 721 2001-12-29  Akim Demaille  <akim@epita.fr>
 722
 723         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 724         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 725         as states.
 726
 727 2001-12-29  Akim Demaille  <akim@epita.fr>
 728
 729         * src/lalr.c (build_relations): Rename `states' as `states1'.
 730         Sorry, I don't understand exactly what it is, no better name...
 731
 732 2001-12-29  Akim Demaille  <akim@epita.fr>
 733
 734         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 735         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 736         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 737         as rules.
 738
 739 2001-12-29  Akim Demaille  <akim@epita.fr>
 740
 741         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 742         ago.
 743
 744 2001-12-29  Akim Demaille  <akim@epita.fr>
 745
 746         * src/reader.c, src/reader.h (user_toknums): Remove.
 747         Adjust all users to use symbols[i]->user_token_number.
 748
 749 2001-12-29  Akim Demaille  <akim@epita.fr>
 750
 751         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 752         Adjust all users to use symbols[i]->prec or ->assoc.
 753
 754 2001-12-29  Akim Demaille  <akim@epita.fr>
 755
 756         * src/reader.c, src/reader.h (tags): Remove.
 757         Adjust all users to use symbols[i]->tag.
 758
 759 2001-12-29  Akim Demaille  <akim@epita.fr>
 760
 761         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 762         and rule_table.
 763         * src/reader.c (packsymbols): Fill this table.
 764         Drop sprec.
 765         * src/conflicts.c (resolve_sr_conflict): Adjust.
 766         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 767         single table.
 768         Use symbols[i]->tag instead of tags[i].
 769
 770 2001-12-29  Akim Demaille  <akim@epita.fr>
 771
 772         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 773         In addition, put a comment in there, to replace...
 774         * tests/regression.at (%union and C comments): Remove.
 775
 776 2001-12-29  Akim Demaille  <akim@epita.fr>
 777
 778         * tests/regression.at (Web2c Actions): Blindly move the actual
 779         output as expected output.  The contents *seem* right to me, but I
 780         can't pretend reading perfectly parser tables...  Nonetheless, all
 781         the other tests pass correctly, the table look OK, even though the
 782         presence of `$axiom' is to be noted: AFAICS it is useless (but
 783         harmless).
 784
 785 2001-12-29  Akim Demaille  <akim@epita.fr>
 786
 787         * src/reader.c (readgram): Don't add the rule 0 if there were no
 788         rules read.  In other words, add it _after_ having performed
 789         grammar sanity checks.
 790         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 791
 792 2001-12-29  Akim Demaille  <akim@epita.fr>
 793
 794         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 795         visible, and some states have now a different number.
 796
 797 2001-12-29  Akim Demaille  <akim@epita.fr>
 798
 799         * src/reader.c (readgram): Bind the initial rule's lineno to that
 800         of the first rule.
 801         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 802         (Solved SR Conflicts): Adjust rule 0's line number.
 803
 804 2001-12-29  Akim Demaille  <akim@epita.fr>
 805
 806         Fix the `GAWK Grammar' failure.
 807
 808         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 809         the reductions of the first state which was mistakenly confused
 810         with the final state because precisely final_state was initialized
 811         to 0.
 812         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 813         now noticed by Bison.
 814         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 815         have a reduction on $default.
 816
 817 2001-12-29  Akim Demaille  <akim@epita.fr>
 818
 819         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 820         rule line numbers.
 821         * src/closure.c (print_closure): Likewise.
 822         * src/derives.c (print_derives): Likewise.
 823         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 824         now.
 825
 826 2001-12-29  Akim Demaille  <akim@epita.fr>
 827
 828         * src/lalr.c (lookaheads_print): New.
 829         (lalr): Call it when --trace-flag.
 830         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 831         are dumped.
 832
 833 2001-12-29  Akim Demaille  <akim@epita.fr>
 834
 835         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 836         when walking through ritem, even via rule->rhs.
 837         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 838         (useful_production, useless_nonterminals): Likewise.
 839         (reduce_grammar_tables): Likewise, plus update nritems.
 840         * src/nullable.c (set_nullable): Likewise.
 841         * src/lalr.c (build_relations): Likewise.
 842         * tests/sets.at (Nullable): Adjust.
 843         Fortunately, now, the $axiom is no longer nullable.
 844
 845 2001-12-29  Akim Demaille  <akim@epita.fr>
 846
 847         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 848         the 0-sentinel.
 849         * src/gram.c (ritem_longest_rhs): Likewise.
 850         * src/reduce.c (nonterminals_reduce): Likewise.
 851         * src/print_graph.c (print_graph): Likewise.
 852         * src/output.c (output_rule_data): Likewise.
 853         * src/nullable.c (set_nullable):  Likewise.
 854
 855 2001-12-29  Akim Demaille  <akim@epita.fr>
 856
 857         * src/output.c: Comment changes.
 858
 859 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 860
 861         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 862         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 863         Sparc, as they were causing more porting problems than the
 864         (minor) performance improvement was worth.
 865
 866         Also, catch up with 1.31's YYSTD.
 867
 868 2001-12-27  Akim Demaille  <akim@epita.fr>
 869
 870         * src/output.c (output_gram): Rely on nritems, not the
 871         0-sentinel.  See below.
 872         Use -1 as separator, not 0.
 873         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 874         Rely on -1 as separator in yyrhs, instead of 0.
 875         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 876         twice `Now at end of input', therefore there are two lines less to
 877         expect.
 878
 879 2001-12-27  Akim Demaille  <akim@epita.fr>
 880
 881         * tests/regression.at (Unresolved SR Conflicts):
 882         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 883         below.
 884
 885 2001-12-27  Akim Demaille  <akim@epita.fr>
 886
 887         * src/LR0.c (new_state): Recognize the final state by the fact it
 888         is reached by eoftoken.
 889         (insert_start_shifting_state, insert_eof_shifting_state)
 890         (insert_accepting_state, augment_automaton): Remove, since now
 891         these states are automatically computed from the initial state.
 892         (generate_states): Adjust.
 893         * src/print.c: When reporting a rule number to the user, substract
 894         1, so that the axiom rule is rule 0, and the first user rule is 1.
 895         * src/reduce.c: Likewise.
 896         * src/print_graph.c (print_core): For the time being, just as for
 897         the report, depend upon --trace-flags to dump the full set of
 898         items.
 899         * src/reader.c (readgram): Once the grammar read, insert the rule
 900         0: `$axiom: START-SYMBOL $'.
 901         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 902         number of the states has changed (the final state is no longer
 903         necessarily the last), catch up.
 904
 905 2001-12-27  Akim Demaille  <akim@epita.fr>
 906
 907         Try to make the use of the eoftoken valid.  Given that its value
 908         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 909         is used instead of > 0 where appropriate, (ii), depend upon nritems
 910         instead of the 0-sentinel.
 911
 912         * src/gram.h, src/gram.c (nritems): New.
 913         Expected to be duplication of nitems, but for the time being...
 914         * src/reader.c (packgram): Assert nritems and nitems are equal.
 915         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 916         * src/closure.c (print_closure, print_fderives): Likewise.
 917         * src/gram.c (ritem_print): Likewise.
 918         * src/print.c (print_core, print_grammar): Likewise.
 919         * src/print_graph.c: Likewise.
 920
 921 2001-12-27  Akim Demaille  <akim@epita.fr>
 922
 923         * src/main.c (main): If there are complains after grammar
 924         reductions, then output the report anyway if requested, then die.
 925         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 926         * src/reader.c (eoftoken): New.
 927         (parse_token_decl): If the token being defined has value `0', it
 928         is the eoftoken.
 929         (packsymbols): No longer hack `tags' to insert `$' by hand.
 930         Be sure to preserve the value of the eoftoken.
 931         (reader): Make sure eoftoken is defined.
 932         Initialize nsyms to 0: now eoftoken is created just like the others.
 933         * src/print.c (print_grammar): Don't special case the eof token.
 934         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 935         lie anyway, albeit pleasant.
 936         * tests/calc.at: Exercise error messages with eoftoken.
 937         Change the grammar so that empty input is invalid.
 938         Adjust expectations.
 939         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 940
 941 2001-12-27  Akim Demaille  <akim@epita.fr>
 942
 943         * configure.in: Check the protos of strchr ans strspn.
 944         Replace strchr if needed.
 945         * src/system.h: Provide the protos of strchr, strspn and memchr if
 946         missing.
 947         * lib/strchr.c: New.
 948         * src/reader.c (symbols_save): Use strchr.
 949
 950 2001-12-27  Akim Demaille  <akim@epita.fr>
 951
 952         * src/print.c, src/print_graph.c (escape): New.
 953         Use it to quote the TAGS outputs.
 954         * src/print_graph.c (print_state): Now errors are in red, and
 955         reductions in green.
 956         Prefer high to wide: output the state number on a line of its own.
 957
 958 2001-12-27  Akim Demaille  <akim@epita.fr>
 959
 960         * src/state.h, src/state.c (reductions_new): New.
 961         * src/LR0.c (set_state_table): Let all the states have a
 962         `reductions', even if reduced to 0.
 963         (save_reductions): Adjust.
 964         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 965         * src/print.c (print_reductions, print_actions): Adjust.
 966         * src/output.c (action_row): Adjust.
 967
 968 2001-12-27  Akim Demaille  <akim@epita.fr>
 969
 970         * src/state.h, src/state.c (errs_new, errs_dup): New.
 971         * src/LR0.c (set_state_table): Let all the states have an errs,
 972         even if reduced to 0.
 973         * src/print.c (print_errs, print_reductions): Adjust.
 974         * src/output.c (output_actions, action_row): Adjust.
 975         * src/conflicts.c (resolve_sr_conflict): Adjust.
 976
 977 2001-12-27  Akim Demaille  <akim@epita.fr>
 978
 979         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 980
 981 2001-12-27  Akim Demaille  <akim@epita.fr>
 982
 983         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 984         * src/print.c: here.
 985         (lookaheadset, shiftset): New, used as additional storage by
 986         print_reductions.
 987         (print_results): Adjust.
 988         (print_shifts, print_gotos, print_errs): New, extracted from...
 989         (print_actions): here.
 990         * src/print_graph.c (print_actions): Remove dead code.
 991
 992 2001-12-27  Akim Demaille  <akim@epita.fr>
 993
 994         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 995         `$n' and `@n'.
 996
 997 2001-12-27  Akim Demaille  <akim@epita.fr>
 998
 999         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
1000         (build_relations): Adjust.
1001
1002 2001-12-27  Akim Demaille  <akim@epita.fr>
1003
1004         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
1005         duplication.
1006
1007 2001-12-27  Akim Demaille  <akim@epita.fr>
1008
1009         * src/reader.c (packgram): Catch nitems overflows.
1010
1011 2001-12-27  Akim Demaille  <akim@epita.fr>
1012
1013         * src/files.c, src/files.h (guard_obstack): Remove.
1014         * src/output.c (output): Adjust.
1015         * src/reader.c (parse_braces): New, factoring...
1016         (copy_action, copy_guard): these two which are renamed as...
1017         (parse_action, parse_guard): these.
1018         As a voluntary consequence, using braces around guards is now
1019         mandatory.
1020
1021 2001-12-27  Akim Demaille  <akim@epita.fr>
1022
1023         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1024         * src/reader.c (symbol_list): `guard' and `guard_line' are new
1025         members.
1026         (symbol_list_new): Adjust.
1027         (copy_action): action_line is the first line, not the last.
1028         (copy_guard): Just as for actions, store the `action' only, not
1029         the switch/case/break flesh.
1030         Don't parse the user action that might follow the guard, let...
1031         (readgram): do it, i.e., now, there can be an action after a
1032         guard.
1033         In other words the guard is just explicitly optional.
1034         (packgram): Adjust.
1035         * src/output.c (guards_output): New.
1036         (output_parser): Call it when needed.
1037         (output): Also free the guard and attrs obstacks.
1038         * src/files.c, src/files.h (obstack_save): Remove.
1039         (output_files): Remove.
1040         As a result, if one needs the former `.act' file, using an
1041         appropriate skeleton which requires actions and guards is now
1042         required.
1043         * src/main.c (main): Adjust.
1044         * tests/semantic.at: New.
1045         * tests/regression.at: Use `input.y' as input file name.
1046         Avoid 8+3 problems by requiring input.c when the test needs the
1047         parser.
1048
1049 2001-12-27  Akim Demaille  <akim@epita.fr>
1050
1051         * src/reader.c (symbol_list_new): Be sure to initialize all the
1052         fields.
1053
1054 2001-12-27  Akim Demaille  <akim@epita.fr>
1055
1056         All the hacks using a final pseudo state are now useless.
1057
1058         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1059         * src/lalr.c (nLA): New.
1060         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1061         instead of lookaheadsp from the pseudo state (nstate + 1).
1062
1063 2001-12-27  Akim Demaille  <akim@epita.fr>
1064
1065         * src/output.c (action_row, token_actions): Use a state_t instead
1066         of a integer, and nlookaheads instead of the following state's
1067         lookaheadsp.
1068
1069 2001-12-27  Akim Demaille  <akim@epita.fr>
1070
1071         * src/conflicts.c (log_resolution, flush_shift)
1072         (resolve_sr_conflict, set_conflicts, solve_conflicts)
1073         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1074         (conflicts_print, print_reductions): Use a state_t instead of an
1075         integer when referring to a state.
1076         As much as possible, depend upon nlookaheads, instead of the
1077         `lookaheadsp' member of the following state (since lookaheads of
1078         successive states are successive, the difference between state n + 1
1079         and n served as the number of lookaheads for state n).
1080         * src/lalr.c (add_lookback_edge): Likewise.
1081         * src/print.c (print_core, print_actions, print_state)
1082         (print_results): Likewise.
1083         * src/print_graph.c (print_core, print_actions, print_state)
1084         (print_graph): Likewise.
1085         * src/conflicts.h: Adjust.
1086
1087 2001-12-27  Akim Demaille  <akim@epita.fr>
1088
1089         * src/bison.hairy: Formatting/comment changes.
1090         ANSIfy.
1091         Remove `register' indications.
1092         Add plenty of `static'.
1093
1094 2001-12-27  Akim Demaille  <akim@epita.fr>
1095
1096         * src/output.c (prepare): Drop the muscle `ntbase' which
1097         duplicates ntokens.
1098         * src/bison.simple: Formatting/comment changes.
1099         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1100         is an undocumented synonym.
1101
1102 2001-12-22  Akim Demaille  <akim@epita.fr>
1103
1104         * src/output.c (output_table_data): Change the prototype to use
1105         `int' for array ranges: some invocations do pass an int, not a
1106         short.
1107         Reported by Wayne Green.

1110
1111         Some actions of web2c.y are improperly triggered.
1112         Reported by Mike Castle.
1113
1114         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1115         * tests/regression.at (Web2c): Rename as...
1116         (Web2c Report): this.
1117         (Web2c Actions): New.
1118
1119 2001-12-22  Akim Demaille  <akim@epita.fr>
1120
1121         Reductions in web2c.y are improperly reported.
1122         Reported by Mike Castle.
1123
1124         * src/conflicts.c (print_reductions): Fix.
1125         * tests/regression.at (Web2c): New.
1126
1127 2001-12-18  Akim Demaille  <akim@epita.fr>
1128
1129         Some host fail on `assert (!"foo")', which expands to
1130         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1131         Reported by Nelson Beebee.
1132
1133         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1134         `#define it_succeeded 0' and `assert (it_succeeded)'.
1135
1136 2001-12-17  Marc Autret  <autret_m@epita.fr>
1137
1138         * src/bison.simple: Don't hard code the skeleton line and filename.
1139         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1140         New line counter 'skeleton_line' (skeleton-line muscle).
1141
1142 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1143
1144         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1145         YYDEBUG must be defined to a nonzero value.
1146
1147         * src/bison.simple (yytname): Do not assume that the user defines
1148         YYDEBUG to a properly parenthesized expression.
1149
1150 2001-12-17  Akim Demaille  <akim@epita.fr>
1151
1152         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1153         nlookaheads is a new member.
1154         Adjust all users.
1155         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1156         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1157         state.
1158
1159 2001-12-17  Akim Demaille  <akim@epita.fr>
1160
1161         * src/files.h, src/files.c (open_files, close_files): Remove.
1162         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1163         let...
1164         * src/reader.c (reader): Do it.
1165
1166 2001-12-17  Akim Demaille  <akim@epita.fr>
1167
1168         * src/conflicts.c (print_reductions): Formatting changes.
1169
1170 2001-12-17  Akim Demaille  <akim@epita.fr>
1171
1172         * src/conflicts.c (flush_shift): Also adjust lookaheadset.
1173         (flush_reduce): New.
1174         (resolve_sr_conflict): Adjust.
1175
1176 2001-12-17  Akim Demaille  <akim@epita.fr>
1177
1178         * src/output.c (output_obstack): Be static and rename as...
1179         (format_obstack): this, to avoid any confusion with files.c's
1180         output_obstack.
1181         * src/reader.h (muscle_obstack): Move to...
1182         * src/output.h: here, since it's defined in output.c.
1183
1184 2001-12-17  Akim Demaille  <akim@epita.fr>
1185
1186         * src/output.c (action_row, save_column, default_goto)
1187         (sort_actions, matching_state, pack_vector): Better variable
1188         locality.
1189
1190 2001-12-17  Akim Demaille  <akim@epita.fr>
1191
1192         * src/output.c: Various formatting changes.
1193
1194 2001-12-17  Akim Demaille  <akim@epita.fr>
1195
1196         * src/files.c (output_files): Free the output_obstack.
1197         * src/main.c (main): Call print and print_graph conditionally.
1198         * src/print.c (print): Work unconditionally.
1199         * src/print_graph.c (print_graph): Work unconditionally.
1200         * src/conflicts.c (log_resolution): Output only if verbose_flag.
1201
1202 2001-12-16  Marc Autret  <autret_m@epita.fr>
1203
1204         * src/output.c (actions_output): Fix. When we use %no-lines,
1205         there is one less line per action.
1206
1207 2001-12-16  Marc Autret  <autret_m@epita.fr>
1208
1209         * src/bison.simple: Remove a useless #line directive.
1210         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1211         * src/output.c (get_lines_number): New.
1212         (output_parser): Adjust, now takes care about the lines of a
1213         output muscles.
1214         Fix line numbering.
1215         (actions_output): Computes the number of lines taken by actions.
1216         (output_master_parser): Insert new skeleton which is the name of
1217         the output parser file name.
1218
1219 2001-12-15  Marc Autret  <autret_m@epita.fr>
1220
1221         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1222
1223 2001-12-15  Marc Autret  <autret_m@epita.fr>
1224
1225         * src/output.c (output_gram): Keep track of the hairy one.
1226
1227 2001-12-15  Akim Demaille  <akim@epita.fr>
1228
1229         Make `make distcheck' work.
1230
1231         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1232         system.h which uses libgettext.h.
1233
1234 2001-12-15  Akim Demaille  <akim@epita.fr>
1235
1236         * src/nullable.c (set_nullable): Useless rules must be skipped,
1237         otherwise, since we range over their symbols, we might look at a
1238         nonterminal which no longer ``exists'', i.e., it is not counted in
1239         `nvars', hence we overflow our arrays.
1240
1241 2001-12-15  Akim Demaille  <akim@epita.fr>
1242
1243         The header can also be produced directly, without any obstack!
1244         Yahoo!
1245
1246         * src/files.c, src/files.h (defines_obstack): Remove.
1247         (compute_header_macro): Global.
1248         (defines_obstack_save): Remove.
1249         * src/reader.c (parse_union_decl): No longer output to
1250         defines_obstack: its content can be found in the `stype' muscle
1251         anyway.
1252         (output_token_translations): Merge into...
1253         (symbols_output): this.
1254         Rename as...
1255         (symbols_save): this.
1256         (reader): Adjust.
1257         * src/output.c (header_output): New.
1258         (output): Call it.
1259
1260 2001-12-15  Akim Demaille  <akim@epita.fr>
1261
1262         * src/reader.c (parse_union_decl): Instead of handling two obstack
1263         simultaneously, use one to define the `stype' muscle, and use the
1264         value of the latter to fill defines_obstack.
1265         (copy_comment): Remove.
1266         (copy_comment2): Work for a single obstack.
1267         Rename as...
1268         (copy_comment): this.
1269
1270 2001-12-15  Akim Demaille  <akim@epita.fr>
1271
1272         * src/lex.c, src/lex.h (xgetc): No longer static.
1273         * src/reader.c (parse_union_decl): Revamp.
1274
1275 2001-12-15  Akim Demaille  <akim@epita.fr>
1276
1277         Still making progress in separating Bison into (i) input, (ii)
1278         process, (iii) output: now we can directly output the parser file
1279         without using table_obstack at all.
1280
1281         * src/files.c, src/files.h (table_obstack): Bye bye.
1282         (parser_file_name): New.
1283         * src/files.c (compute_output_file_names): Compute it.
1284         * src/output.c (actions_output, output_parser)
1285         (output_master_parser): To a file instead of an obstack.
1286
1287 2001-12-15  Akim Demaille  <akim@epita.fr>
1288
1289         Attach actions to rules, instead of pre-outputting them to
1290         actions_obstack.
1291
1292         * src/gram.h (rule_t): action and action_line are new members.
1293         * src/reader.c (symbol_list): Likewise.
1294         (copy_action): Save the actions within the rule.
1295         (packgram): Save them in rule_table.
1296         * src/output.c (actions_output): New.
1297         (output_parser): Use it on `%%actions'.
1298         (output_rule_data): Don't free rule_table.
1299         (output): Do it.
1300         (prepare): Don't save the `action' muscle.
1301         * src/bison.simple: s/%%action/%%actions/.
1302
1303 2001-12-15  Akim Demaille  <akim@epita.fr>
1304
1305         * src/reader.c (copy_action): When --yacc, don't append a `;'
1306         to the user action: let it fail if lacking.
1307         Suggested by Arnold Robbins and Tom Tromey.
1308
1309 2001-12-14  Akim Demaille  <akim@epita.fr>
1310
1311         * src/lex.c (literalchar): Simply return the char you decoded, non
1312         longer mess around with obstacks and int pointers.
1313         Adjust all callers.
1314
1315 2001-12-14  Akim Demaille  <akim@epita.fr>
1316
1317         * src/lex.c (literalchar): Don't escape the special characters,
1318         just decode them, and keep them as char (before, eol was output as
1319         the 2 char string `\n' etc.).
1320         * src/output.c (output_rule_data): Use quotearg to output the
1321         token strings.
1322
1323 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1324
1325         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1326         Do not infringe on the global user namespace when using C++.
1327         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1328         All uses of `fprintf' and `stderr' changed.
1329
1330         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1331
1332 2001-12-13  Akim Demaille  <akim@epita.fr>
1333
1334         The computation of nullable is broken: it doesn't handle empty
1335         RHS's properly.
1336
1337         * tests/torture.at (GNU AWK Grammar): New.
1338         * tests/sets.at (Nullable): New.
1339         * src/nullable.c (set_nullable): Instead of blindly looping over
1340         `ritems', loop over the rules, and then over their rhs's.
1341
1342         Work around Autotest bugs.
1343
1344         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1345         frame, because Autotest understand lines starting with a `+' as
1346         traces from the shell.  Then, they are not processed properly.
1347         Admittedly an Autotest bug, but we don't have time to wait for
1348         Autotest to catch up.
1349         * tests/regression.at (Broken Closure): Adjust to the new table
1350         frames.
1351         Move to...
1352         * tests/sets.at: here.
1353
1354 2001-12-13  Akim Demaille  <akim@epita.fr>
1355
1356         * src/closure.c (closure): Use nrules instead of playing tricks
1357         with BITS_PER_WORD.
1358
1359 2001-12-13  Akim Demaille  <akim@epita.fr>
1360
1361         * src/print.c (print_actions): Output the handling of `$' as the
1362         traces do: shifting the token EOF.  Before EOF was treated as a
1363         nonterminal.
1364         * tests/regression.at: Adjust some tests.
1365         * src/print_graph.c (print_core): Complete the set of items via
1366         closure.  The next-to-final and final states are still unsatisfying,
1367         but that's to be addressed elsewhere.
1368         No longer output the rule numbers, but do output the state number.
1369         A single loop for the shifts + gotos is enough, but picked a
1370         distinct color for each.
1371         (print_graph): Initialize and finalize closure.
1372
1373 2001-12-13  Akim Demaille  <akim@epita.fr>
1374
1375         * src/reader.c (readgram): Remove dead code, an strip useless
1376         braces.
1377         (get_type): Remove, unused.
1378
1379 2001-12-12  Akim Demaille  <akim@epita.fr>
1380
1381         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1382         on that of lib/error.c.
1383
1384 2001-12-12  Akim Demaille  <akim@epita.fr>
1385
1386         Some hosts don't like `/' in includes.
1387
1388         * src/system.h: Include libgettext.h without qualifying the path.
1389         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1390         $(top_srcdir).
1391
1392 2001-12-11  Marc Autret  <autret_m@epita.fr>
1393
1394         * src/output.c (output_parser): Remove useless muscle.
1395
1396 2001-12-11  Marc Autret  <autret_m@epita.fr>
1397
1398         * src/bison.simple: Remove #line just before %%epilogue. It
1399         is now handled in ...
1400         * src/reader.c (read_additionnal_code): Add the output of a
1401         #line for the epilogue.
1402
1403 2001-12-10  Marc Autret  <autret_m@epita.fr>
1404
1405         * src/reader.c (copy_definition): Re-use CPP-outed code which
1406         replace precedent remove.
1407         * src/bison.simple: Remove #line before %%prologue because
1408         %%input-line is wrong at this time.
1409
1410 2001-12-10  Marc Autret  <autret_m@epita.fr>
1411
1412         * src/reader.c (symbols_output): Clean up.
1413         * src/output.c (output_gram, output): Clean up.
1414
1415 2001-12-10  Akim Demaille  <akim@epita.fr>
1416
1417         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1418         * src/LR0.c (set_state_table): here.
1419         * src/lalr.c (lalr): Call it.
1420
1421 2001-12-10  Akim Demaille  <akim@epita.fr>
1422
1423         * src/state.h (shifts): Remove the `number' member: shifts are
1424         attached to state, hence no longer need to be labelled with a
1425         state number.
1426
1427 2001-12-10  Akim Demaille  <akim@epita.fr>
1428
1429         Now that states have a complete set of members, the linked list of
1430         shifts is useless: just fill directly the state's shifts member.
1431
1432         * src/state.h (shifts): Remove the `next' member.
1433         * src/LR0.c (first_state, last_state): Remove.
1434         Adjust the callers.
1435         (augment_automaton): Don't look for the shifts that must be added
1436         a shift on EOF: it is those of the state we looked for!  But now,
1437         since shifts are attached, it is no longer needed to looking
1438         merely by its id: its number.
1439
1440 2001-12-10  Akim Demaille  <akim@epita.fr>
1441
1442         * src/LR0.c (augment_automaton): Better variable locality.
1443         Remove an impossible branch: if there is a state corresponding to
1444         the start symbol being shifted, then there is shift for the start
1445         symbol from the initial state.
1446
1447 2001-12-10  Akim Demaille  <akim@epita.fr>
1448
1449         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1450         only when appropriate: when insert_start_shifting_state' is not
1451         invoked.
1452         * tests/regression.at (Rule Line Numbers): Adjust.
1453
1454 2001-12-10  Akim Demaille  <akim@epita.fr>
1455
1456         * src/LR0.c (augment_automaton): Now that all states have shifts,
1457         merge the two cases addition shifts to the initial state.
1458

1461         * src/lalr.c (set_state_table): Move to...
1462         * src/LR0.c: here.
1463         * src/lalr.c (lalr): Don't call it...
1464         * src/LR0.c (generate_states): do it.
1465         * src/LR0.h (first_state): Remove, only the table is used.
1466
1467 2001-12-10  Akim Demaille  <akim@epita.fr>
1468
1469         * src/LR0.h (first_shift, first_reduction): Remove.
1470         * src/lalr.c: Don't use first_shift: find shifts through the
1471         states.
1472
1473 2001-12-10  Akim Demaille  <akim@epita.fr>
1474
1475         * src/LR0.c: Attach shifts to states as soon as they are
1476         computed.
1477         * src/lalr.c (set_state_table): Instead of assigning shifts to
1478         state, just assert that the mapping was properly done.
1479
1480 2001-12-10  Akim Demaille  <akim@epita.fr>
1481
1482         * src/LR0.c (insert_start_shift): Rename as...
1483         (insert_start_shifting_state): this.
1484         (insert_eof_shifting_state, insert_accepting_state): New.
1485         (augment_automaton): Adjust.
1486         Better locality of the variables.
1487         When looking if the start_symbol is shifted from the initial
1488         state, using `while (... symbol != start_symbol ...)' sounds
1489         better than `while (... symbol < start_symbol ...)': If fail
1490         to see how the order between symbols could be relevant!
1491
1492 2001-12-10  Akim Demaille  <akim@epita.fr>
1493
1494         * src/getargs.h: Don't declare `spec_name_prefix' and
1495         `spec_file_prefix', declared by src/files.h.
1496         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1497         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1498         * src/output.c (prepare): Adjust.
1499         * src/reader.c (symbols_output): Likewise.
1500         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1501
1502 2001-12-10  Akim Demaille  <akim@epita.fr>
1503
1504         * src/muscle_tab.c (muscle_init): NULL is a better default than
1505         `"0"'.
1506
1507 2001-12-10  Akim Demaille  <akim@epita.fr>
1508
1509         * src/reader.c (reader): Calling symbols_output once is enough.
1510
1511 2001-12-10  Akim Demaille  <akim@epita.fr>
1512
1513         Now that states have a complete set of members, the linked list of
1514         reductions is useless: just fill directly the state's reductions
1515         member.
1516
1517         * src/state.h (struct reductions): Remove member `number' and
1518         `next'.
1519         * src/LR0.c (first_reduction, last_reduction): Remove.
1520         (save_reductions): Don't link the new reductions, store them in
1521         this_state.
1522         * src/lalr.c (set_state_table): No need to attach reductions to
1523         states, it's already done.
1524         * src/output.c (output_actions): No longer free the shifts, then
1525         the reductions, then the states: free all the states and their
1526         members.
1527
1528 2001-12-10  Akim Demaille  <akim@epita.fr>
1529
1530         * src/options.c (OPTN, DRTV, BOTH): New.
1531         (option_table): Use them.
1532
1533         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1534         the job of system.h.
1535         * src/options.c: Don't include stdio.h and xalloc.h for the same
1536         reasons.
1537
1538 2001-12-10  Akim Demaille  <akim@epita.fr>
1539
1540         * src/output.c (output, prepare): Make sure the values of the
1541         muscles `action' and `prologue' are 0-terminated.
1542
1543 2001-12-10  Akim Demaille  <akim@epita.fr>
1544
1545         Clean up GCC warnings.
1546
1547         * src/reader.c (copy_action): `buf' is not used.
1548         (parse_skel_decl): Be static.
1549         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1550         * src/options.h (create_long_option_table): Have a real prototype.
1551         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1552         (hash_delete_at): Return const void *.
1553         Adjust casts to preserve the const.
1554
1555 2001-12-10  Akim Demaille  <akim@epita.fr>
1556
1557         * configure.in: Require 2.52g.
1558         M4 is not needed, but AUTOM4TE is.
1559         * m4/m4.m4: Remove.
1560         * tests/Makefile.am: Adjust.
1561
1562 2001-12-10  Akim Demaille  <akim@epita.fr>
1563
1564         One structure for states is enough, even though theoretically
1565         there are LR(0) states and LALR(1) states.
1566
1567         * src/lalr.h (state_t): Remove.
1568         (state_table): Be state_t **, not state_t *.
1569         * src/state.h (core, CORE_ALLOC): Rename as...
1570         (state_t, STATE_ALLOC): this.
1571         Add the LALR(1) members: shifts, reductions, errs.
1572         * src/LR0.c (state_table): Rename as...
1573         (state_hash): this, to avoid name clashes with the global
1574         `state_table'.
1575         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1576         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
1577
1578 2001-12-10  Akim Demaille  <akim@epita.fr>
1579
1580         Bison dumps core on bash.y.
1581         Reported by Pascal Bart.
1582
1583         * src/warshall.c (bitmatrix_print): New.
1584         (TC): Use it.
1585         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1586         j must be the outer loop.
1587         * tests/regression.at (Broken Closure): New.
1588
1589 2001-12-05  Akim Demaille  <akim@epita.fr>
1590
1591         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1592         its argument.
1593         Reported by Peter Hámorský.
1594
1595 2001-12-05  Akim Demaille  <akim@epita.fr>
1596
1597         * src/conflicts.c (err_table): Remove.
1598         (resolve_sr_conflict): Adjust.
1599         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1600         Rename as...
1601         (state_t.reductions, state_t.shifts): this.
1602
1603 2001-12-05  Akim Demaille  <akim@epita.fr>
1604
1605         * src/reduce.c (reduce_grammar_tables): No longer disable the
1606         removal of useless rules via CPP but via `if (0)', so that the
1607         compiler still check the code is valid.
1608         For instance, it should have noticed `rline' no longer exists: use
1609         the `line' member of rule_t.
1610         * src/gram.c (dummy, rline): Remove, unused.
1611
1612 2001-12-05  Akim Demaille  <akim@epita.fr>
1613
1614         * src/output.c (pack_vector): Use assert, not berror.
1615         * src/main.c (berror): Remove, unused.
1616
1617 2001-12-05  Akim Demaille  <akim@epita.fr>
1618
1619         New experimental feature: if --verbose --trace output all the
1620         items of a state, not only its kernel.
1621
1622         * src/print.c (print_core): If `trace_flag', then invoke closure
1623         before outputting the items of the state (print_core is no longer
1624         a correct name them).
1625         (print_results): Invoke new_closure/free_closure if needed.
1626
1627 2001-12-05  Akim Demaille  <akim@epita.fr>
1628
1629         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1630         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1631         (nitemset): for consistency with the rest of the project.
1632
1633 2001-12-05  Akim Demaille  <akim@epita.fr>
1634
1635         * src/closure.c (print_closure): Improve.
1636         (closure): Use it for printing input and output.
1637
1638 2001-12-05  Akim Demaille  <akim@epita.fr>
1639
1640         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1641         indexed by nonterminals.
1642
1643 2001-12-05  Akim Demaille  <akim@epita.fr>
1644
1645         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1646         what it was!).
1647         * src/warshall.h: Remove accidental duplication of the content.
1648
1649 2001-12-05  Akim Demaille  <akim@epita.fr>
1650
1651         * src/closure.c (set_fderives): De-obfuscate.
1652
1653 2001-12-05  Akim Demaille  <akim@epita.fr>
1654

1660
1661 2001-12-05  Akim Demaille  <akim@epita.fr>
1662
1663         * src/output.c (action_row): De-obfuscate
1664         using the good o' techniques: arrays not pointers, variable
1665         locality, BITISSET, RESETBIT etc.
1666
1667 2001-12-05  Akim Demaille  <akim@epita.fr>
1668
1669         Pessimize the code to simplify it: from now on, all the states
1670         have a valid SHIFTS, which NSHIFTS is possibly 0.
1671
1672         * src/LR0.c (shifts_new): Be global and move to..
1673         * src/state.c, src/state.h: here.
1674         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1675         * src/print_graph: Adjust.
1676
1677 2001-12-05  Akim Demaille  <akim@epita.fr>
1678
1679         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1680         * src/conflicts.c: Use it.
1681         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1682         incorrectly ``simplified''.
1683
1684 2001-12-05  Akim Demaille  <akim@epita.fr>
1685
1686         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1687         using the good o' techniques: arrays not pointers, variable
1688         locality, BITISSET, RESETBIT etc.
1689
1690 2001-12-05  Akim Demaille  <akim@epita.fr>
1691
1692         * src/state.h (SHIFT_SYMBOL): New.
1693         * src/conflicts.c: Use it to deobfuscate.
1694
1695 2001-12-05  Akim Demaille  <akim@epita.fr>
1696
1697         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1698         (print_reductions): De-obfuscate using the good o' techniques:
1699         arrays not pointers, variable locality, BITISSET.
1700
1701 2001-12-05  Akim Demaille  <akim@epita.fr>
1702
1703         * src/conflicts.c (print_reductions): Arrays, not pointers.
1704         Use BITISSET.
1705
1706 2001-12-05  Akim Demaille  <akim@epita.fr>
1707
1708         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1709
1710 2001-12-05  Akim Demaille  <akim@epita.fr>
1711
1712         * src/conflicts.c (print_reductions): Improve variable locality.

1715

1721
1722 2001-12-05  Akim Demaille  <akim@epita.fr>
1723
1724         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1725         * src/lalr.c: Use them.
1726
1727 2001-12-05  Akim Demaille  <akim@epita.fr>
1728
1729         * src/LR0.c (augment_automaton): Formatting changes.
1730         Better variable locality.
1731
1732 2001-12-05  Akim Demaille  <akim@epita.fr>
1733
1734         * src/lalr.c (matrix_print): New.
1735         (transpose): Use it.
1736         Use arrays instead of pointers.
1737
1738 2001-12-05  Akim Demaille  <akim@epita.fr>
1739
1740         * src/lalr.c (maxrhs): Move to...
1741         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1742         * src/lalr.c (build_relations): Adjust.
1743
1744 2001-12-05  Akim Demaille  <akim@epita.fr>
1745
1746         * src/lalr.c (transpose): Free the memory allocated to the
1747         argument, as it is replaced by the results by the unique caller.
1748         (build_relations): Merely invoke transpose: it handles the memory
1749         deallocation.
1750         Improve variable locality.
1751         Avoid variables used as mere abbreviations.
1752         (compute_lookaheads): Use arrays instead of pointers.
1753
1754 2001-12-05  Akim Demaille  <akim@epita.fr>
1755
1756         * src/lalr.c (initialize_F): Improve variable locality.
1757         Avoid variables used as mere abbreviations.
1758
1759 2001-12-05  Akim Demaille  <akim@epita.fr>
1760
1761         * src/derives.c (print_derives): Display the ruleno.
1762         * src/lalr.c (initialize_F, transpose): Better variable locality
1763         to improve readability.
1764         Avoid variables used as mere abbreviations.
1765
1766 2001-12-05  Akim Demaille  <akim@epita.fr>
1767
1768         * src/lalr.c (traverse): Use arrays instead of pointers.
1769
1770 2001-12-05  Akim Demaille  <akim@epita.fr>
1771
1772         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1773         the handling of squeue.
1774         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1775
1776 2001-12-05  Akim Demaille  <akim@epita.fr>
1777
1778         Because useless nonterminals are now kept alive (instead of being
1779         `destroyed'), we now sometimes examine them, and store information
1780         related to them.  Hence we need to know their number, and adjust
1781         memory allocations.
1782
1783         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1784         static.
1785         * src/LR0.c (allocate_itemsets): The memory allocated to
1786         `symbol_count' was used for two different purpose: once to count
1787         the number of occurrences of each symbol, and later reassigned to
1788         `shift_symbol', containing the symbol that can be shifted from a
1789         given state.
1790         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1791         only, and...
1792         (new_itemsets): Allocate `shift_symbol' here.
1793         (allocate_itemsets): symbol_count includes useless nonterminals.
1794         Make room for them.
1795         (free_storage): Use `free', not `XFREE', for pointers that cannot
1796         be null.
1797
1798 2001-12-05  Akim Demaille  <akim@epita.fr>
1799
1800         * src/nullable.c (set_nullable): Deobfuscate the handling of
1801         ritem.
1802         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1803
1804 2001-12-05  Akim Demaille  <akim@epita.fr>
1805
1806         * src/gram.c, src/gram.h (ritem_print): New.
1807         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1808         (This useless function was defined only to work around VMS linkers
1809         that can't handle compilation units with variables only).
1810         * src/reduce.c (dump_grammar): Use it to trace the construction of
1811         ritem.
1812
1813 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1814
1815         * src/bison.simple (union yyalloc): Change member names
1816         to be the same as the stack names.
1817         (yyparse): yyptr is now union yyalloc *, not char *.
1818         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1819         and may generate better code on some machines.
1820         (yystpcpy): Use prototype if __STDC__ is defined, not just
1821         if __cplusplus is defined.
1822

1824
1825         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1826         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1827         Gettext doesn't compile cleanly, and dies with -Werror.
1828         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1829         Include WARNING_CFLAGS here.
1830         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1831         before being defined.

1839         (quotearg_n_options): Abort if N is negative.
1840         Avoid overflow check on hosts where size_t is 64 bits and int
1841         is 32 bits, as overflow is impossible there.
1842         Fix off-by-one typo that caused unnecessary reallocation.
1843
1844 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1845
1846         Name space cleanup in generated parser.
1847
1848         * doc/bison.texinfo (Bison Parser): Discuss system headers
1849         and their effect on the user name space.
1850
1851         * src/bison.simple:
1852         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1853         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1854         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1855
1856         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1857         on user names when possible.
1858
1859         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1860         Simplify test for whather <alloca.h> exists.
1861
1862         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.

1875         All uses changed.
1876
1877         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1878         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1879         and YYSTACK_FREE instead of malloc and free.

1895
1896 2001-11-30  Akim Demaille  <akim@epita.fr>
1897
1898         Instead of mapping the LHS of unused rules to -1, keep the LHS

1916
1917         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1918         useless nonterminals, move them at the end of the symbol arrays.

1935         (union yyalloc): New type.
1936         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1937         an arbitrary restriction on hosts where size_t is wider than int.
1938
1939         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1940         a parser stack overflow.  Allocate just one block of memory for all
1941         three stacks, instead of allocating three blocks; this typically is
1942         faster and reduces fragmentation.
1943
1944         Do not limit the number of items in the stack to a value that fits
1945         in 'int', as this is an arbitrary limit on hosts with 64-bit
1946         size_t and 32-bit int.
1947
1948 2001-11-29  Marc Autret  <autret_m@epita.fr>

2002

2005
2006 2001-11-28  Akim Demaille  <akim@epita.fr>
2007
2008         * src/closure.c (closure): No longer optimize the special case
2009         where all the bits of `ruleset[r]' are set to 0, to make the code
2010         clearer.

2013

2374         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2375         now the tests are run in private dirs, therefore AC_CLEANUP and

2403         arg_offset.

3325
3326         * src/bison.simple (yyparse): Don't take the address of an

3336         completely wrong.

3375         bound to true.
3376         (read_declarations): Add case for macro definition.
3377         (copy_identifier): New.

3413         with something new. Skeletons are now processed character by character
3414         rather than line by line, and Bison looks for '%%' macros. This is the
3415         first step in making Bison's output process (a lot) more flexible.
3416         (output_parser): Use the macro table.

3744
3745         * src/reader.c (gensym): `gensym_count' is your own.
3746         Use a static buf to create the symbol name, as token_buffer is no
3747         longer a buffer.
3748
3749 2001-02-08  Akim Demaille  <akim@epita.fr>
3750
3751         * src/conflicts.c (conflict_report): Be sure not to append to res
3752         between two calls, which could happen if both first sprintf were

3758         New, from fileutils 4.0.37.
3759         * configure.in: Require Autoconf 2.49c.  I took some time before
3760         making this decision.  This is the only way out for portability
3761         issues in Bison, it would mean way too much duplicate effort to
3762         import in Bison features implemented in 2.49c since 2.13.
3763         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

3774
3775         * src/lex.c (token_obstack): New.
3776         (init_lex): Initialize it.  No longer call...

3781
3782         * src/lex.h: Rename all the tokens:
3783         s/\bENDFILE\b/tok_eof/g;
3784         s/\bIDENTIFIER\b/tok_identifier/g;
3785         etc.
3786         Let them be enums, not #define, to ease debugging.
3787         Adjust all the code.
3788
3789 2001-01-18  Akim Demaille  <akim@epita.fr>
3790
3791         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

3793
3794 2001-01-18  Akim Demaille  <akim@epita.fr>
3795
3796         Since we now use obstacks, more % directives can be enabled.
3797
3798         * src/lex.c (percent_table): Also accept `%yacc',
3799         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3800         `%debug'.
3801         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3802         instead of returning a token.
3803         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3804         * src/reader.c (read_declarations): Adjust.
3805         * src/files.c (open_files): Don't call `compute_base_names', don't
3806         compute `attrsfile' since they depend upon data which might be
3807         *in* the input file now.
3808         (output_files): Do it here.
3809         * src/output.c (output_headers): Document the fact that this patch
3810         introduces a guaranteed SEGV for semantic parsers.
3811         * doc/bison.texinfo: Document them.

3835         FILE * parameters.
3836
3837 2000-12-20  Akim Demaille  <akim@epita.fr>
3838
3839         * src/files.c (open_files): Actually the `.output' file is based
3840         on the short_base_name, not base_name.
3841         * tests/suite.at (Checking output file names): Adjust.
3842
3843 2000-12-20  Akim Demaille  <akim@epita.fr>
3844
3845         * src/bison.s1: Remove, we now use directly...

3869         (stringappend): Be just like strcat but allocate.
3870         (base_names): Eve out from open_files.
3871         Try to simplify the rather hairy computation of base_name and
3872         short_base_name.
3873         (open_files): Use it.
3874         * tests/suite.at (Checking output file names): New test.

3884
3885 2000-12-19  Akim Demaille  <akim@epita.fr>
3886
3887         * src/output.c (output_parser): Compute the `#line' lines when
3888         there are.
3889         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.

3891
3892 2000-12-19  Akim Demaille  <akim@epita.fr>
3893
3894         Let the handling of the skeleton files be local to the procedures

3947         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3948         prevents type checking.
3949         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3950         cast the value to (void *): assigning a `foo *' to a `void *'
3951         variable is valid.
3952         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3953         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
3954         append characters.

3969
3970         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
3971         macros.

3988
3989 2000-11-07  Akim Demaille  <akim@epita.fr>
3990
3991         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

4001         `address' for consistency.  Qualify it `const'.

4003         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
4004         `const' their input argument (`data' or `address').

4011         Adjust dependencies.
4012
4013 2000-11-03  Akim Demaille  <akim@epita.fr>

4015         For some reason, this was not applied.
4016
4017         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

4033         * src/main.c (main): Don't use `atexit' to register `done', since
4034         it no longer has to remove tmp files, just call `output_files'
4035         when there are no errors.
4036
4037 2000-11-02  Akim Demaille  <akim@epita.fr>

4138 2000-10-04  Akim Demaille  <akim@epita.fr>
4139
4140         When a literal string is used to define two different tokens,
4141         `bison -v' segfaults.
4142         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4143
4144         * tests/regression.m4: New file.
4145         Include the core of the sample provided by Piotr Gackiewicz.
4146         * src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
4147         properly.
4148
4149 2000-10-04  Akim Demaille  <akim@epita.fr>
4150
4151         * src/reader.c (parse_expect_decl): Keep `count' within the size
4152         of `buffer'.
4153         From Neil Booth.
4154
4155 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4156
4157         * bison.s1 (yyparse): Assign the default value
4158         unconditionally, to avoid a GCC warning and make the parser a
4159         tad smaller.
4160
4161 2000-10-02  Akim Demaille  <akim@epita.fr>
4162
4163         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4164         options.
4165
4166 2000-10-02  Akim Demaille  <akim@epita.fr>
4167
4168         * src/derives.c, src/print.c, src/reduce.c: To ease the
4169         translation, move some `\n' out of the translated strings.
4170
4171 2000-10-02  Akim Demaille  <akim@epita.fr>
4172
4173         The location tracking mechanism is precious for parse error
4174         messages.  Nevertheless, it is enabled only when `@n' is used in
4175         the grammar, which is a different issue (you can use it in error
4176         message, but not in the grammar per se).  Therefore, there should
4177         be another means to enable it.
4178
4179         * src/getargs.c (getargs): Support `--locations'.
4180         (usage): Report it.
4181         * src/getargs.h (locationsflag): Export it.
4182         * src/lex.c (percent_table): Support `%locations'.
4183         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4184         with `locationsflag'.
4185         * doc/bison.texinfo: Document `--locations' and `%locations'.
4186         Sort the options.
4187         * tests/calc.m4: Test it.
4188
4189         For regularity of the names, replace each
4190         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4191         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4192         In addition replace each `flag' with `_flag'.
4193
4194 2000-10-02  Akim Demaille  <akim@epita.fr>
4195
4196         Also test parse error messages, including with YYERROR_VERBOSE.
4197
4198         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4199         associative).
4200         Use it to check the computations.
4201         Use it to check `nonassoc' is honored.
4202         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4203         `--yyerror-verbose'.
4204         (_AT_CHECK_CALC): Adjust to this option.
4205         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4206
4207 2000-10-02  Akim Demaille  <akim@epita.fr>
4208
4209         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4210         the latter demonstrates a flaw in the handling of non debugging
4211         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4212         was used in order to simplify:
4213
4214         #if YYDEBUG
4215         if (yydebug)
4216         {
4217         ...
4218         }
4219         #endif
4220
4221         into
4222
4223         if (yydebug)
4224         {
4225         ...
4226         }
4227
4228         unfortunately this leads to a CPP conflict when
4229         `--name-prefix=foo' is used since it produces `#define yydebug
4230         foodebug'.
4231
4232         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4233         (YYDPRINTF): New macro.
4234         Spread its use.
4235         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4236         the bison options.
4237         Also test `--verbose', `--defines' and `--name-prefix'.
4238
4239 2000-10-02  Akim Demaille  <akim@epita.fr>
4240
4241         Improve the readability of the produced parsers.
4242
4243         * src/bison.s1: Formatting changes.
4244         Improve the comment related to the `$' mark.
4245         (yydefault): Don't fall through to `yyresume': `goto' there.
4246         * src/output.c (output_parser): When the `$' is met, skip the end
4247         of its line.
4248         New variable, `number_of_dollar_signs', to check there's exactly
4249         one `$' in the parser skeleton.
4250
4251 2000-10-02  Akim Demaille  <akim@epita.fr>
4252
4253         * lib/xstrdup.c: New file, from the fileutils.
4254         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4255         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4256         instead of strlen + xmalloc + strcpy.
4257         * src/symtab.c (copys): Remove, use xstrdup instead.
4258
4259 2000-10-02  Akim Demaille  <akim@epita.fr>
4260
4261         * src/gram.h (associativity): New enum type which replaces the
4262         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4263         `right_assoc', `left_assoc' and `non_assoc'.
4264         Adjust all dependencies.
4265         * src/reader.c: Formatting changes.
4266         (LTYPESTR): Don't define it, use it as a literal in
4267         `reader_output_yylsp'.
4268         * src/symtab.h (symbol_class): New enum type which replaces the
4269         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4270         `sunknown', `stoken and `snterm'.
4271
4272 2000-10-02  Akim Demaille  <akim@epita.fr>
4273
4274         * src/getargs.c (fixed_outfiles): Rename as...
4275         (yaccflag): for consistency and accuracy.
4276         Adjust dependencies.
4277
4278 2000-10-02  Akim Demaille  <akim@epita.fr>
4279
4280         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4281         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4282         difficult and introduced a lot of core dump.  It turns out that
4283         Bison used an implementation of `xmalloc' based on `calloc', and
4284         at various places it does depend upon the initialization to 0.  I
4285         have not tried to isolate the pertinent places, and all the former
4286         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4287         someone should address this issue.
4288
4289         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4290         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4291         files.
4292         Adjust dependencies.
4293         * src/warshall.h: New file.
4294         Propagate.
4295
4296 2000-10-02  Akim Demaille  <akim@epita.fr>
4297
4298         Various anti-`extern in *.c' changes.
4299
4300         * src/system.h: Include `assert.h'.
4301
4302 2000-10-02  Akim Demaille  <akim@epita.fr>
4303
4304         * src/state.h (nstates, final_state, first_state, first_shift)

4383
4384         * src/output.c (token_actions): Introduce a temporary array,
4385         YYDEFACT, that makes it possible for this function to use
4386         output_short_table.
4387
4388 2000-10-02  Akim Demaille  <akim@epita.fr>
4389
4390         `user_toknums' is output as a `short[]' in `output.c', while it is
4391         defined as a `int[]' in `reader.c'.  For consistency with the
4392         other output tables, `user_toknums' is now defined as a table of
4393         shorts.
4394
4395         * src/reader.c (user_toknums): Be a short table instead of an int

4434         inclusion.
4435         Don't define PARAMS.
4436         * src/system.h: Define PARAMS.
4437         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4438         purpose of config.h.  system.h must not try to fix wrong
4439         definitions in config.h.

4627         copy_comment.  Removed now unused `match', `ended',
4628         `cplus_comment'.
4629         (copy_comment, copy_string): Moved, to be visible from
4630         copy_definition.

4656
4657         Change the handling of @s so that they behave exactly like $s.
4658         There is now a pseudo variable @$ (readble and writable), location
4659         of the lhs of the rule (by default ranging from the location of
4660         the first symbol of the rhs, to the location of the last symbol,
4661         or, if the rhs is empty, YYLLOC).

4667         (after the $): No longer change `*YYLSP', just stack YYLOC the
4668         same way you stack YYVAL.
4669         * src/reader.c (read_declarations): Use warns.
4670         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

4696         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

4734         locale files.
4735         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4736         builddir.
4737         * acinclude.m4: Remove, replaced by the directory m4.
4738         * m4/Makefile.am (EXTRA_DIST): New variable.
