 335
 336         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 337         more consistent when naming methods and variables.  Put preprocessor
 338         directives around tables only needed for debugging.

 340 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>

 382         (token_definitions_output): No longer keeps track of the output
 383         line number, hence remove the second argument.
 384         (guards_output): Check against the guard member of a rule, not the
 385         action member.
 386         Adjust callers.
 387         (output_skeleton): Don't look for the skeleton location, let m4 do
 388         that.
 389         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 390         file will be used.
 391         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 392         (prepare): Given that for the time being changesyntax is not
 393         usable in M4, rename the muscles using `-' to `_'.
 394         Define `defines_flag', `output_parser_name' and `output_header_name'.
 395         * src/output.h (actions_output, guards_output)
 396         (token_definitions_output): Adjust prototypes.
 397         * src/scan-skel.l: Instead of scanning the skeletons, it now
 398         processes the output of m4: `__oline__' and `#output'.
 399         * data/bison.simple: Adjust to be used by M4(sugar).
 400         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 401         to date.
 402         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 403         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 404         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 405         shamelessly stolen from CVS Autoconf.
 406
 407 2002-02-05  Akim Demaille  <akim@epita.fr>
 408
 409         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
 410         * configure.in: Check for the declarations of free and malloc.
 411         * src/muscle_tab.c: Adjust.
 412
 413 2002-02-05  Akim Demaille  <akim@epita.fr>
 414
 415         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
 416         which have no values.
 417
 418 2002-02-05  Akim Demaille  <akim@epita.fr>
 419
 420         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
 421         * data/: here.
 422
 423 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 424
 425         * src/bison.simple (YYSIZE_T): Do not define merely because
 426         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 427         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 428
 429 2002-01-27  Akim Demaille  <akim@epita.fr>
 430
 431         Fix `%nonassoc and eof'.
 432
 433         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 434         which were not properly copied!  Replace
 435         memcpy (res->errs, src->errs, src->nerrs);
 436         with
 437         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 438         !!!
 439         * tests/regression.at (%nonassoc and eof): Adjust to newest
 440         Autotest: `.' is not in the PATH.
 441
 442 2002-01-27  Akim Demaille  <akim@epita.fr>
 443
 444         * tests/sets.at (AT_EXTRACT_SETS): New.
 445         (Nullable): Use it.
 446         (Firsts): New.
 447
 448 2002-01-26  Akim Demaille  <akim@epita.fr>
 449
 450         * tests/actions.at, tests/calc.at, tests/headers.at,
 451         * tests/torture.at: Adjust to the newest Autotest which no longer
 452         forces `.' in the PATH.
 453
 454 2002-01-25  Akim Demaille  <akim@epita.fr>
 455
 456         * tests/regression.at (%nonassoc and eof): New.
 457         Suggested by Robert Anisko.
 458
 459 2002-01-24  Akim Demaille  <akim@epita.fr>
 460
 461         Bison dumps core when trying to complain about broken input files.
 462         Reported by Cris van Pelt.
 463
 464         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 465         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 466         into...
 467         (Invalid inputs): Strengthen: exercise parse_percent_token.
 468
 469 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 470
 471         * src/Makefile.am: Add bison.c++.
 472         * src/bison.c++: New skeleton.
 473
 474 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 475
 476         * po/it.po: New.
 477
 478 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 479
 480         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 481
 482 2002-01-20  Marc Autret  <marc@gnu.org>
 483
 484         * src/files.c (compute_output_file_names): Fix
 485
 486 2002-01-20  Marc Autret  <marc@gnu.org>
 487
 488         * tests/output.at: New test.
 489         * src/files.c (compute_base_names): Don't map extensions when
 490         the YACC flag is set, use defaults.
 491         Reported by Evgeny Stambulchik.
 492
 493 2002-01-20  Marc Autret  <marc@gnu.org>
 494
 495         * src/system.h: Need to define __attribute__ away for non-GCC
 496         compilers as well (i.e. the vendor C compiler).
 497         Suggested by Albert Chin-A-Young.
 498
 499 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 500
 501         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 502         canonical definition.
 503         * src/system.h: Use the canonical definition for PARAMS (avoids
 504         a conflict with the macro from lib/hash.h).
 505
 506 2002-01-11  Akim Demaille  <akim@epita.fr>
 507
 508         * configure.in: Use AC_FUNC_STRNLEN.
 509         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 510
 511 2002-01-09  Akim Demaille  <akim@epita.fr>
 512
 513         * src/files.c, src/files.h (output_infix): New.
 514         (tab_extension): Remove.
 515         (compute_base_names): Compute the former, drop the latter.
 516         * src/output.c (prepare): Insert the muscles `output-infix', and
 517         `output-suffix'.
 518         * src/parse-skel.y (string, string.1): New.
 519         (section.header): Use it.
 520         (section.yacc): Remove.
 521         (prefix): Remove too.
 522         * src/scan-skel.l: Adjust.
 523         * src/bison.simple, src/bison.hairy: Adjust.
 524
 525 2002-01-09  Akim Demaille  <akim@epita.fr>
 526
 527         * configure.in (WERROR_CFLAGS): Compute it.
 528         * src/Makefile.am (CFLAGS): Pass it.
 529         * tests/atlocal.in (CFLAGS): Idem.
 530         * src/files.c: Fix a few warnings.
 531         (get_extension_index): Remove, unused.
 532
 533 2002-01-08  Akim Demaille  <akim@epita.fr>
 534
 535         * src/getargs.c (AS_FILE_NAME): New.
 536         (getargs): Use it to convert DOSish file names.
 537         * src/files.c (base_name): Rename as full_base_name to avoid
 538         clashes with `base_name ()'.
 539         (filename_split): New.
 540         (compute_base_names): N-th rewrite, using filename_split.
 541
 542 2002-01-08  Akim Demaille  <akim@epita.fr>
 543
 544         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 545         New, stolen from the Fileutils 4.1.
 546         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 547         * configure.in: Check for the presence of memrchr, and of its
 548         prototype.
 549
 550 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 551
 552         * lib/hash.h (__P): Added definition for this macro.
 553         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 554         BUILT_SOURCES, to ensure they are generated first.
 555         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 556         %error-verbose to allow bootstrapping with bison 1.30x.
 557
 558 2002-01-06  Akim Demaille  <akim@epita.fr>
 559
 560         * src/reader.c (parse_braces): Don't fetch the next char, the
 561         convention is to fetch on entry.
 562         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 563         'switch' without a following semicolon.
 564         * tests/regression.at (braces parsing): New.
 565
 566 2002-01-06  Akim Demaille  <akim@epita.fr>
 567
 568         Bison is dead wrong in its RR conflict reports.
 569
 570         * tests/torture.at (GNU Cim Grammar): New.
 571         * src/conflicts.c (count_rr_conflicts): Fix.
 572
 573 2002-01-06  Akim Demaille  <akim@epita.fr>
 574
 575         Creating package.m4 from configure.ac causes too many problems.
 576
 577         * tests/Makefile.am (package.m4): Create it by hand,
 578         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 579
 580 2002-01-06  Akim Demaille  <akim@epita.fr>
 581
 582         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 583         skeleton.h.
 584
 585 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 586
 587         * doc/bison.texinfo (Debugging):
 588         Remove YYSTDERR; it's no longer defined or used.
 589         Also, s/cstdio.h/cstdio/.
 590
 591 2002-01-03  Akim Demaille  <akim@epita.fr>
 592
 593         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 594
 595 2002-01-03  Akim Demaille  <akim@epita.fr>
 596
 597         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 598         tracing code to --trace, wait for a better --trace option, with
 599         args.
 600
 601 2002-01-03  Akim Demaille  <akim@epita.fr>
 602
 603         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 604         The ISO C++ standard is extremely clear about it: stderr is
 605         considered a macro, not a regular symbol (see table 94 `Header
 606         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 607         Therefore std:: does not apply to it.  It still does with fprintf.
 608         Also, s/cstdio.h/cstdio/.
 609
 610 2002-01-03  Akim Demaille  <akim@epita.fr>
 611
 612         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 613         for non system headers.
 614
 615 2002-01-02  Akim Demaille  <akim@epita.fr>
 616
 617         Equip the skeleton chain with location tracking, runtime trace,
 618         pure parser and scanner.
 619
 620         * src/parse-skel.y: Request a pure parser, locations, and prefix
 621         renaming.
 622         (%union): Having several members with the same type does not help
 623         type mismatches, simplify.
 624         (YYPRINT, yyprint): New.
 625         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 626         (skel_error): this.
 627         Handle locations.
 628         * src/scan-skel.l: Adjust to these changes.
 629         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 630         (LOCATION_PRINT, skel_control_t): New.
 631
 632 2001-12-30  Akim Demaille  <akim@epita.fr>
 633
 634         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 635         replace `gb' with BLANKS.
 636         * src/scan-skel.l: Adjust.
 637
 638 2001-12-30  Akim Demaille  <akim@epita.fr>
 639
 640         * src/system.h: We don't need nor want bcopy.
 641         Throw away MS-DOS crap: we don't need getpid.
 642         * configure.in: We don't need strndup.  It was even causing
 643         problems: because Flex includes the headers *before* us,
 644         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 645         not visible.
 646         * lib/xstrndup.c: New.
 647         * src/scan-skel.l: Use it.
 648         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 649         * src/parse-skel.y: Use %directives instead of #defines.
 650
 651 2001-12-30  Akim Demaille  <akim@epita.fr>
 652
 653         * src/skeleton.h: New.
 654         * src/output.c (output_parser, output_master_parser): Remove, dead
 655         code.
 656         * src/output.h (get_lines_number, actions_output, guards_output)
 657         (token_definitions_output): Prototype them.
 658         * src/parse-skel.y: Add the license notice.
 659         Include output.h and skeleton.h.
 660         (process_skeleton): Returns void, and takes a single parameter.
 661         * src/scan-skel.l: Add the license notice.
 662         Include skeleton.h.
 663         Don't use %option yylineno: it seems that then Flex imagines
 664         REJECT has been used, and therefore it won't reallocate its
 665         buffers (which makes no other sense to me than a bug).  It results
 666         in warnings for `unused: yy_flex_realloc'.
 667
 668 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 669
 670         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 671         (MUSCLE_INSERT_PREFIX): ...to there.
 672         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 673         (MUSCLE_INSERT_PREFIX): Move from here...
 674
 675         * src/bison.hairy: Add a section directive.  Put braces around muscle
 676         names.  This parser skeleton is still broken, but Bison should not
 677         choke on a bad muscle 'syntax'.
 678         * src/bison.simple: Add a section directive.  Put braces around muscle
 679         names.
 680
 681         * src/files.h (strsuffix, stringappend): Add declarations.
 682         (tab_extension): Add declaration.
 683         (short_base_name): Add declaration.
 684
 685         * src/files.c (strsuffix, stringappend): No longer static.  These
 686         functions are used in the skeleton parser.
 687         (tab_extension): New.
 688         (compute_base_names): Use the computations done in this function
 689         to guess if the generated parsers should have '.tab' in their
 690         names.
 691         (short_base_name): No longer static.
 692
 693         * src/output.c (output_skeleton): New.
 694         (output): Disable call to output_master_parser, and give a try to
 695         a new skeleton handling system.
 696         (guards_output, actions_output): No longer static.
 697         (token_definitions_output, get_lines_number): No longer static.
 698
 699         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 700
 701         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 702         parse-skel.y.
 703
 704         * src/parse-skel.y: New file.
 705         * src/scan-skel.l: New file.
 706
 707 2001-12-29  Akim Demaille  <akim@epita.fr>
 708
 709         %name-prefix is broken.
 710
 711         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 712         Adjust all dependencies.
 713         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 714         %name-prefix.
 715
 716         Renaming yylval but not yylloc is not consistent.  Now we do.
 717
 718         * src/bison.simple: Prefix yylloc if used.
 719         * doc/bison.texinfo (Decl Summary): Document that.
 720
 721 2001-12-29  Akim Demaille  <akim@epita.fr>
 722
 723         * doc/bison.texinfo: Promote `%long-directive' over
 724         `%long_directive'.
 725         Remove all references to fixed-output-files, yacc is enough.
 726
 727 2001-12-29  Akim Demaille  <akim@epita.fr>
 728
 729         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 730         user prologue.  These are defaults.
 731         * tests/actions.at (Mid-rule actions): Make sure the user can
 732         define YYDEBUG and YYERROR_VERBOSE.
 733
 734 2001-12-29  Akim Demaille  <akim@epita.fr>
 735
 736         * src/output.c (header_output): Don't forget to export YYLTYPE and
 737         yylloc.
 738         * tests/headers.at (export YYLTYPE): New, make sure it does.
 739         * tests/regression.at (%union and --defines, Invalid CPP headers):
 740         Move to...
 741         * tests/headers.at: here.
 742
 743 2001-12-29  Akim Demaille  <akim@epita.fr>
 744
 745         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 746
 747 2001-12-29  Akim Demaille  <akim@epita.fr>
 748
 749         * tests/actions.at (Mid-rule actions): Output on a single line
 750         instead of several.
 751
 752 2001-12-29  Akim Demaille  <akim@epita.fr>
 753
 754         * doc/bison.texinfo: Formatting changes.
 755
 756 2001-12-29  Akim Demaille  <akim@epita.fr>
 757
 758         Don't store the token defs in a muscle, just be ready to output it
 759         on command.  Now possible via `symbols'.  Fixes a memory leak.
 760
 761         * src/output.c (token_definitions_output): New.
 762         (output_parser, header_output): Use it.
 763         * src/reader.c (symbols_save): Remove.
 764
 765 2001-12-29  Akim Demaille  <akim@epita.fr>
 766
 767         * src/bison.simple: Do not provide a default for YYSTYPE and
 768         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 769         default.
 770
 771 2001-12-29  Akim Demaille  <akim@epita.fr>
 772
 773         Mid-rule actions are simply... ignored!
 774
 775         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 776         the empty-rule associated to the dummy symbol, not to the host
 777         rule.
 778         * tests/actions.at (Mid-rule actions): New.
 779
 780 2001-12-29  Akim Demaille  <akim@epita.fr>
 781
 782         Memory leak.
 783
 784         * src/reader.c (reader): Free grammar.
 785
 786 2001-12-29  Akim Demaille  <akim@epita.fr>
 787
 788         Memory leak.
 789
 790         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 791         since it allocates it for each state, although only one is needed.
 792         (allocate_storage): Do it here.
 793
 794 2001-12-29  Akim Demaille  <akim@epita.fr>
 795
 796         * src/options.h, src/options.c (create_long_option_table): Rename
 797         as...
 798         (long_option_table_new): this, with a clearer prototype.
 799         (percent_table): Remove, unused,
 800         * src/getargs.c (getargs): Adjust.
 801
 802 2001-12-29  Akim Demaille  <akim@epita.fr>
 803
 804         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 805         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 806         as states.
 807
 808 2001-12-29  Akim Demaille  <akim@epita.fr>
 809
 810         * src/lalr.c (build_relations): Rename `states' as `states1'.
 811         Sorry, I don't understand exactly what it is, no better name...
 812
 813 2001-12-29  Akim Demaille  <akim@epita.fr>
 814
 815         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 816         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 817         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 818         as rules.
 819
 820 2001-12-29  Akim Demaille  <akim@epita.fr>
 821
 822         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 823         ago.
 824
 825 2001-12-29  Akim Demaille  <akim@epita.fr>
 826
 827         * src/reader.c, src/reader.h (user_toknums): Remove.
 828         Adjust all users to use symbols[i]->user_token_number.
 829
 830 2001-12-29  Akim Demaille  <akim@epita.fr>
 831
 832         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 833         Adjust all users to use symbols[i]->prec or ->assoc.
 834
 835 2001-12-29  Akim Demaille  <akim@epita.fr>
 836
 837         * src/reader.c, src/reader.h (tags): Remove.
 838         Adjust all users to use symbols[i]->tag.
 839
 840 2001-12-29  Akim Demaille  <akim@epita.fr>
 841
 842         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 843         and rule_table.
 844         * src/reader.c (packsymbols): Fill this table.
 845         Drop sprec.
 846         * src/conflicts.c (resolve_sr_conflict): Adjust.
 847         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 848         single table.
 849         Use symbols[i]->tag instead of tags[i].
 850
 851 2001-12-29  Akim Demaille  <akim@epita.fr>
 852
 853         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 854         In addition, put a comment in there, to replace...
 855         * tests/regression.at (%union and C comments): Remove.
 856
 857 2001-12-29  Akim Demaille  <akim@epita.fr>
 858
 859         * tests/regression.at (Web2c Actions): Blindly move the actual
 860         output as expected output.  The contents *seem* right to me, but I
 861         can't pretend reading perfectly parser tables...  Nonetheless, all
 862         the other tests pass correctly, the table look OK, even though the
 863         presence of `$axiom' is to be noted: AFAICS it is useless (but
 864         harmless).
 865
 866 2001-12-29  Akim Demaille  <akim@epita.fr>
 867
 868         * src/reader.c (readgram): Don't add the rule 0 if there were no
 869         rules read.  In other words, add it _after_ having performed
 870         grammar sanity checks.
 871         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 872
 873 2001-12-29  Akim Demaille  <akim@epita.fr>
 874
 875         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 876         visible, and some states have now a different number.
 877
 878 2001-12-29  Akim Demaille  <akim@epita.fr>
 879
 880         * src/reader.c (readgram): Bind the initial rule's lineno to that
 881         of the first rule.
 882         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 883         (Solved SR Conflicts): Adjust rule 0's line number.
 884
 885 2001-12-29  Akim Demaille  <akim@epita.fr>
 886
 887         Fix the `GAWK Grammar' failure.
 888
 889         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 890         the reductions of the first state which was mistakenly confused
 891         with the final state because precisely final_state was initialized
 892         to 0.
 893         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 894         now noticed by Bison.
 895         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 896         have a reduction on $default.
 897
 898 2001-12-29  Akim Demaille  <akim@epita.fr>
 899
 900         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 901         rule line numbers.
 902         * src/closure.c (print_closure): Likewise.
 903         * src/derives.c (print_derives): Likewise.
 904         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 905         now.
 906
 907 2001-12-29  Akim Demaille  <akim@epita.fr>
 908
 909         * src/lalr.c (lookaheads_print): New.
 910         (lalr): Call it when --trace-flag.
 911         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 912         are dumped.
 913
 914 2001-12-29  Akim Demaille  <akim@epita.fr>
 915
 916         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 917         when walking through ritem, even via rule->rhs.
 918         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 919         (useful_production, useless_nonterminals): Likewise.
 920         (reduce_grammar_tables): Likewise, plus update nritems.
 921         * src/nullable.c (set_nullable): Likewise.
 922         * src/lalr.c (build_relations): Likewise.
 923         * tests/sets.at (Nullable): Adjust.
 924         Fortunately, now, the $axiom is no longer nullable.
 925
 926 2001-12-29  Akim Demaille  <akim@epita.fr>
 927
 928         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 929         the 0-sentinel.
 930         * src/gram.c (ritem_longest_rhs): Likewise.
 931         * src/reduce.c (nonterminals_reduce): Likewise.
 932         * src/print_graph.c (print_graph): Likewise.
 933         * src/output.c (output_rule_data): Likewise.
 934         * src/nullable.c (set_nullable):  Likewise.
 935
 936 2001-12-29  Akim Demaille  <akim@epita.fr>
 937
 938         * src/output.c: Comment changes.
 939
 940 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 941
 942         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 943         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 944         Sparc, as they were causing more porting problems than the
 945         (minor) performance improvement was worth.
 946
 947         Also, catch up with 1.31's YYSTD.
 948
 949 2001-12-27  Akim Demaille  <akim@epita.fr>
 950
 951         * src/output.c (output_gram): Rely on nritems, not the
 952         0-sentinel.  See below.
 953         Use -1 as separator, not 0.
 954         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 955         Rely on -1 as separator in yyrhs, instead of 0.
 956         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 957         twice `Now at end of input', therefore there are two lines less to
 958         expect.
 959
 960 2001-12-27  Akim Demaille  <akim@epita.fr>
 961
 962         * tests/regression.at (Unresolved SR Conflicts):
 963         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 964         below.
 965
 966 2001-12-27  Akim Demaille  <akim@epita.fr>
 967
 968         * src/LR0.c (new_state): Recognize the final state by the fact it
 969         is reached by eoftoken.
 970         (insert_start_shifting_state, insert_eof_shifting_state)
 971         (insert_accepting_state, augment_automaton): Remove, since now
 972         these states are automatically computed from the initial state.
 973         (generate_states): Adjust.
 974         * src/print.c: When reporting a rule number to the user, substract
 975         1, so that the axiom rule is rule 0, and the first user rule is 1.
 976         * src/reduce.c: Likewise.
 977         * src/print_graph.c (print_core): For the time being, just as for
 978         the report, depend upon --trace-flags to dump the full set of
 979         items.
 980         * src/reader.c (readgram): Once the grammar read, insert the rule
 981         0: `$axiom: START-SYMBOL $'.
 982         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 983         number of the states has changed (the final state is no longer
 984         necessarily the last), catch up.
 985
 986 2001-12-27  Akim Demaille  <akim@epita.fr>
 987
 988         Try to make the use of the eoftoken valid.  Given that its value
 989         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 990         is used instead of > 0 where appropriate, (ii), depend upon nritems
 991         instead of the 0-sentinel.
 992
 993         * src/gram.h, src/gram.c (nritems): New.
 994         Expected to be duplication of nitems, but for the time being...
 995         * src/reader.c (packgram): Assert nritems and nitems are equal.
 996         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 997         * src/closure.c (print_closure, print_fderives): Likewise.
 998         * src/gram.c (ritem_print): Likewise.
 999         * src/print.c (print_core, print_grammar): Likewise.
1000         * src/print_graph.c: Likewise.
1001
1002 2001-12-27  Akim Demaille  <akim@epita.fr>
1003
1004         * src/main.c (main): If there are complains after grammar
1005         reductions, then output the report anyway if requested, then die.
1006         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
1007         * src/reader.c (eoftoken): New.
1008         (parse_token_decl): If the token being defined has value `0', it
1009         is the eoftoken.
1010         (packsymbols): No longer hack `tags' to insert `$' by hand.
1011         Be sure to preserve the value of the eoftoken.
1012         (reader): Make sure eoftoken is defined.
1013         Initialize nsyms to 0: now eoftoken is created just like the others.
1014         * src/print.c (print_grammar): Don't special case the eof token.
1015         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
1016         lie anyway, albeit pleasant.
1017         * tests/calc.at: Exercise error messages with eoftoken.
1018         Change the grammar so that empty input is invalid.
1019         Adjust expectations.
1020         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
1021
1022 2001-12-27  Akim Demaille  <akim@epita.fr>
1023
1024         * configure.in: Check the protos of strchr ans strspn.
1025         Replace strchr if needed.
1026         * src/system.h: Provide the protos of strchr, strspn and memchr if
1027         missing.
1028         * lib/strchr.c: New.
1029         * src/reader.c (symbols_save): Use strchr.
1030
1031 2001-12-27  Akim Demaille  <akim@epita.fr>
1032
1033         * src/print.c, src/print_graph.c (escape): New.
1034         Use it to quote the TAGS outputs.
1035         * src/print_graph.c (print_state): Now errors are in red, and
1036         reductions in green.
1037         Prefer high to wide: output the state number on a line of its own.
1038
1039 2001-12-27  Akim Demaille  <akim@epita.fr>
1040
1041         * src/state.h, src/state.c (reductions_new): New.
1042         * src/LR0.c (set_state_table): Let all the states have a
1043         `reductions', even if reduced to 0.
1044         (save_reductions): Adjust.
1045         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
1046         * src/print.c (print_reductions, print_actions): Adjust.
1047         * src/output.c (action_row): Adjust.
1048
1049 2001-12-27  Akim Demaille  <akim@epita.fr>
1050
1051         * src/state.h, src/state.c (errs_new, errs_dup): New.
1052         * src/LR0.c (set_state_table): Let all the states have an errs,
1053         even if reduced to 0.
1054         * src/print.c (print_errs, print_reductions): Adjust.
1055         * src/output.c (output_actions, action_row): Adjust.
1056         * src/conflicts.c (resolve_sr_conflict): Adjust.
1057
1058 2001-12-27  Akim Demaille  <akim@epita.fr>
1059
1060         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
1061
1062 2001-12-27  Akim Demaille  <akim@epita.fr>
1063
1064         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
1065         * src/print.c: here.
1066         (lookaheadset, shiftset): New, used as additional storage by
1067         print_reductions.
1068         (print_results): Adjust.
1069         (print_shifts, print_gotos, print_errs): New, extracted from...
1070         (print_actions): here.
1071         * src/print_graph.c (print_actions): Remove dead code.
1072
1073 2001-12-27  Akim Demaille  <akim@epita.fr>
1074
1075         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
1076         `$n' and `@n'.
1077
1078 2001-12-27  Akim Demaille  <akim@epita.fr>
1079
1080         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
1081         (build_relations): Adjust.
1082
1083 2001-12-27  Akim Demaille  <akim@epita.fr>
1084
1085         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
1086         duplication.
1087
1088 2001-12-27  Akim Demaille  <akim@epita.fr>
1089
1090         * src/reader.c (packgram): Catch nitems overflows.
1091
1092 2001-12-27  Akim Demaille  <akim@epita.fr>
1093
1094         * src/files.c, src/files.h (guard_obstack): Remove.
1095         * src/output.c (output): Adjust.
1096         * src/reader.c (parse_braces): New, factoring...
1097         (copy_action, copy_guard): these two which are renamed as...
1098         (parse_action, parse_guard): these.
1099         As a voluntary consequence, using braces around guards is now
1100         mandatory.
1101
1102 2001-12-27  Akim Demaille  <akim@epita.fr>
1103
1104         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1105         * src/reader.c (symbol_list): `guard' and `guard_line' are new
1106         members.
1107         (symbol_list_new): Adjust.
1108         (copy_action): action_line is the first line, not the last.
1109         (copy_guard): Just as for actions, store the `action' only, not
1110         the switch/case/break flesh.
1111         Don't parse the user action that might follow the guard, let...
1112         (readgram): do it, i.e., now, there can be an action after a
1113         guard.
1114         In other words the guard is just explicitly optional.
1115         (packgram): Adjust.
1116         * src/output.c (guards_output): New.
1117         (output_parser): Call it when needed.
1118         (output): Also free the guard and attrs obstacks.
1119         * src/files.c, src/files.h (obstack_save): Remove.
1120         (output_files): Remove.
1121         As a result, if one needs the former `.act' file, using an
1122         appropriate skeleton which requires actions and guards is now
1123         required.
1124         * src/main.c (main): Adjust.
1125         * tests/semantic.at: New.
1126         * tests/regression.at: Use `input.y' as input file name.
1127         Avoid 8+3 problems by requiring input.c when the test needs the
1128         parser.
1129
1130 2001-12-27  Akim Demaille  <akim@epita.fr>
1131
1132         * src/reader.c (symbol_list_new): Be sure to initialize all the
1133         fields.
1134
1135 2001-12-27  Akim Demaille  <akim@epita.fr>
1136
1137         All the hacks using a final pseudo state are now useless.
1138
1139         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1140         * src/lalr.c (nLA): New.
1141         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1142         instead of lookaheadsp from the pseudo state (nstate + 1).
1143
1144 2001-12-27  Akim Demaille  <akim@epita.fr>
1145
1146         * src/output.c (action_row, token_actions): Use a state_t instead
1147         of a integer, and nlookaheads instead of the following state's
1148         lookaheadsp.
1149
1150 2001-12-27  Akim Demaille  <akim@epita.fr>

1154         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1155         (conflicts_print, print_reductions): Use a state_t instead of an
1156         integer when referring to a state.
1157         As much as possible, depend upon nlookaheads, instead of the
1158         `lookaheadsp' member of the following state (since lookaheads of
1159         successive states are successive, the difference between state n + 1
1160         and n served as the number of lookaheads for state n).
1161         * src/lalr.c (add_lookback_edge): Likewise.
1162         * src/print.c (print_core, print_actions, print_state)
1163         (print_results): Likewise.
1164         * src/print_graph.c (print_core, print_actions, print_state)
1165         (print_graph): Likewise.
1166         * src/conflicts.h: Adjust.

1169
1170         * src/bison.hairy: Formatting/comment changes.
1171         ANSIfy.
1172         Remove `register' indications.
1173         Add plenty of `static'.
1174
1175 2001-12-27  Akim Demaille  <akim@epita.fr>
1176
1177         * src/output.c (prepare): Drop the muscle `ntbase' which
1178         duplicates ntokens.
1179         * src/bison.simple: Formatting/comment changes.
1180         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1181         is an undocumented synonym.
1182
1183 2001-12-22  Akim Demaille  <akim@epita.fr>
1184
1185         * src/output.c (output_table_data): Change the prototype to use
1186         `int' for array ranges: some invocations do pass an int, not a
1187         short.
1188         Reported by Wayne Green.

1192         Some actions of web2c.y are improperly triggered.
1193         Reported by Mike Castle.
1194
1195         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1196         * tests/regression.at (Web2c): Rename as...
1197         (Web2c Report): this.
1198         (Web2c Actions): New.
1199
1200 2001-12-22  Akim Demaille  <akim@epita.fr>

1202         Reductions in web2c.y are improperly reported.
1203         Reported by Mike Castle.
1204

1209
1210         Some host fail on `assert (!"foo")', which expands to
1211         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1212         Reported by Nelson Beebee.
1213
1214         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1215         `#define it_succeeded 0' and `assert (it_succeeded)'.
1216
1217 2001-12-17  Marc Autret  <autret_m@epita.fr>
1218
1219         * src/bison.simple: Don't hard code the skeleton line and filename.
1220         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1221         New line counter 'skeleton_line' (skeleton-line muscle).
1222
1223 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1224
1225         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1226         YYDEBUG must be defined to a nonzero value.
1227
1228         * src/bison.simple (yytname): Do not assume that the user defines
1229         YYDEBUG to a properly parenthesized expression.
1230
1231 2001-12-17  Akim Demaille  <akim@epita.fr>
1232
1233         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1234         nlookaheads is a new member.
1235         Adjust all users.
1236         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1237         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1238         state.

1242         * src/files.h, src/files.c (open_files, close_files): Remove.
1243         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1244         let...
1245         * src/reader.c (reader): Do it.
1246
1247 2001-12-17  Akim Demaille  <akim@epita.fr>
1248
1249         * src/conflicts.c (print_reductions): Formatting changes.

1256
1257 2001-12-17  Akim Demaille  <akim@epita.fr>
1258
1259         * src/output.c (output_obstack): Be static and rename as...
1260         (format_obstack): this, to avoid any confusion with files.c's
1261         output_obstack.
1262         * src/reader.h (muscle_obstack): Move to...
1263         * src/output.h: here, since it's defined in output.c.
1264
1265 2001-12-17  Akim Demaille  <akim@epita.fr>
1266
1267         * src/output.c (action_row, save_column, default_goto)
1268         (sort_actions, matching_state, pack_vector): Better variable
1269         locality.
1270
1271 2001-12-17  Akim Demaille  <akim@epita.fr>
1272

1275 2001-12-17  Akim Demaille  <akim@epita.fr>
1276
1277         * src/files.c (output_files): Free the output_obstack.
1278         * src/main.c (main): Call print and print_graph conditionally.
1279         * src/print.c (print): Work unconditionally.
1280         * src/print_graph.c (print_graph): Work unconditionally.
1281         * src/conflicts.c (log_resolution): Output only if verbose_flag.
1282
1283 2001-12-16  Marc Autret  <autret_m@epita.fr>
1284
1285         * src/output.c (actions_output): Fix. When we use %no-lines,
1286         there is one less line per action.
1287
1288 2001-12-16  Marc Autret  <autret_m@epita.fr>
1289
1290         * src/bison.simple: Remove a useless #line directive.
1291         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1292         * src/output.c (get_lines_number): New.
1293         (output_parser): Adjust, now takes care about the lines of a
1294         output muscles.
1295         Fix line numbering.
1296         (actions_output): Computes the number of lines taken by actions.
1297         (output_master_parser): Insert new skeleton which is the name of
1298         the output parser file name.
1299
1300 2001-12-15  Marc Autret  <autret_m@epita.fr>
1301
1302         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1303
1304 2001-12-15  Marc Autret  <autret_m@epita.fr>
1305
1306         * src/output.c (output_gram): Keep track of the hairy one.
1307
1308 2001-12-15  Akim Demaille  <akim@epita.fr>
1309
1310         Make `make distcheck' work.
1311
1312         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1313         system.h which uses libgettext.h.
1314
1315 2001-12-15  Akim Demaille  <akim@epita.fr>
1316
1317         * src/nullable.c (set_nullable): Useless rules must be skipped,
1318         otherwise, since we range over their symbols, we might look at a
1319         nonterminal which no longer ``exists'', i.e., it is not counted in
1320         `nvars', hence we overflow our arrays.
1321
1322 2001-12-15  Akim Demaille  <akim@epita.fr>
1323
1324         The header can also be produced directly, without any obstack!
1325         Yahoo!
1326
1327         * src/files.c, src/files.h (defines_obstack): Remove.
1328         (compute_header_macro): Global.
1329         (defines_obstack_save): Remove.
1330         * src/reader.c (parse_union_decl): No longer output to
1331         defines_obstack: its content can be found in the `stype' muscle
1332         anyway.
1333         (output_token_translations): Merge into...
1334         (symbols_output): this.
1335         Rename as...
1336         (symbols_save): this.
1337         (reader): Adjust.
1338         * src/output.c (header_output): New.
1339         (output): Call it.
1340
1341 2001-12-15  Akim Demaille  <akim@epita.fr>
1342
1343         * src/reader.c (parse_union_decl): Instead of handling two obstack
1344         simultaneously, use one to define the `stype' muscle, and use the
1345         value of the latter to fill defines_obstack.
1346         (copy_comment): Remove.
1347         (copy_comment2): Work for a single obstack.
1348         Rename as...
1349         (copy_comment): this.
1350
1351 2001-12-15  Akim Demaille  <akim@epita.fr>
1352
1353         * src/lex.c, src/lex.h (xgetc): No longer static.
1354         * src/reader.c (parse_union_decl): Revamp.
1355
1356 2001-12-15  Akim Demaille  <akim@epita.fr>
1357
1358         Still making progress in separating Bison into (i) input, (ii)
1359         process, (iii) output: now we can directly output the parser file
1360         without using table_obstack at all.
1361
1362         * src/files.c, src/files.h (table_obstack): Bye bye.
1363         (parser_file_name): New.
1364         * src/files.c (compute_output_file_names): Compute it.
1365         * src/output.c (actions_output, output_parser)
1366         (output_master_parser): To a file instead of an obstack.
1367
1368 2001-12-15  Akim Demaille  <akim@epita.fr>
1369
1370         Attach actions to rules, instead of pre-outputting them to
1371         actions_obstack.
1372
1373         * src/gram.h (rule_t): action and action_line are new members.
1374         * src/reader.c (symbol_list): Likewise.
1375         (copy_action): Save the actions within the rule.
1376         (packgram): Save them in rule_table.
1377         * src/output.c (actions_output): New.
1378         (output_parser): Use it on `%%actions'.
1379         (output_rule_data): Don't free rule_table.
1380         (output): Do it.
1381         (prepare): Don't save the `action' muscle.
1382         * src/bison.simple: s/%%action/%%actions/.
1383
1384 2001-12-15  Akim Demaille  <akim@epita.fr>
1385
1386         * src/reader.c (copy_action): When --yacc, don't append a `;'
1387         to the user action: let it fail if lacking.
1388         Suggested by Arnold Robbins and Tom Tromey.
1389
1390 2001-12-14  Akim Demaille  <akim@epita.fr>
1391
1392         * src/lex.c (literalchar): Simply return the char you decoded, non
1393         longer mess around with obstacks and int pointers.
1394         Adjust all callers.
1395
1396 2001-12-14  Akim Demaille  <akim@epita.fr>
1397
1398         * src/lex.c (literalchar): Don't escape the special characters,
1399         just decode them, and keep them as char (before, eol was output as
1400         the 2 char string `\n' etc.).
1401         * src/output.c (output_rule_data): Use quotearg to output the
1402         token strings.
1403
1404 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1405
1406         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1407         Do not infringe on the global user namespace when using C++.
1408         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1409         All uses of `fprintf' and `stderr' changed.
1410
1411         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1412
1413 2001-12-13  Akim Demaille  <akim@epita.fr>
1414
1415         The computation of nullable is broken: it doesn't handle empty
1416         RHS's properly.
1417
1418         * tests/torture.at (GNU AWK Grammar): New.
1419         * tests/sets.at (Nullable): New.
1420         * src/nullable.c (set_nullable): Instead of blindly looping over
1421         `ritems', loop over the rules, and then over their rhs's.
1422
1423         Work around Autotest bugs.
1424
1425         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1426         frame, because Autotest understand lines starting with a `+' as
1427         traces from the shell.  Then, they are not processed properly.
1428         Admittedly an Autotest bug, but we don't have time to wait for
1429         Autotest to catch up.
1430         * tests/regression.at (Broken Closure): Adjust to the new table
1431         frames.
1432         Move to...
1433         * tests/sets.at: here.
1434
1435 2001-12-13  Akim Demaille  <akim@epita.fr>
1436
1437         * src/closure.c (closure): Use nrules instead of playing tricks
1438         with BITS_PER_WORD.
1439
1440 2001-12-13  Akim Demaille  <akim@epita.fr>
1441
1442         * src/print.c (print_actions): Output the handling of `$' as the
1443         traces do: shifting the token EOF.  Before EOF was treated as a
1444         nonterminal.
1445         * tests/regression.at: Adjust some tests.
1446         * src/print_graph.c (print_core): Complete the set of items via
1447         closure.  The next-to-final and final states are still unsatisfying,
1448         but that's to be addressed elsewhere.
1449         No longer output the rule numbers, but do output the state number.
1450         A single loop for the shifts + gotos is enough, but picked a
1451         distinct color for each.
1452         (print_graph): Initialize and finalize closure.
1453
1454 2001-12-13  Akim Demaille  <akim@epita.fr>
1455
1456         * src/reader.c (readgram): Remove dead code, an strip useless
1457         braces.
1458         (get_type): Remove, unused.
1459
1460 2001-12-12  Akim Demaille  <akim@epita.fr>
1461
1462         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1463         on that of lib/error.c.
1464
1465 2001-12-12  Akim Demaille  <akim@epita.fr>
1466
1467         Some hosts don't like `/' in includes.
1468
1469         * src/system.h: Include libgettext.h without qualifying the path.
1470         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1471         $(top_srcdir).
1472
1473 2001-12-11  Marc Autret  <autret_m@epita.fr>
1474
1475         * src/output.c (output_parser): Remove useless muscle.
1476
1477 2001-12-11  Marc Autret  <autret_m@epita.fr>
1478
1479         * src/bison.simple: Remove #line just before %%epilogue. It
1480         is now handled in ...
1481         * src/reader.c (read_additionnal_code): Add the output of a
1482         #line for the epilogue.
1483
1484 2001-12-10  Marc Autret  <autret_m@epita.fr>
1485
1486         * src/reader.c (copy_definition): Re-use CPP-outed code which
1487         replace precedent remove.
1488         * src/bison.simple: Remove #line before %%prologue because
1489         %%input-line is wrong at this time.
1490
1491 2001-12-10  Marc Autret  <autret_m@epita.fr>
1492
1493         * src/reader.c (symbols_output): Clean up.
1494         * src/output.c (output_gram, output): Clean up.
1495
1496 2001-12-10  Akim Demaille  <akim@epita.fr>
1497
1498         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1499         * src/LR0.c (set_state_table): here.
1500         * src/lalr.c (lalr): Call it.
1501
1502 2001-12-10  Akim Demaille  <akim@epita.fr>
1503
1504         * src/state.h (shifts): Remove the `number' member: shifts are
1505         attached to state, hence no longer need to be labelled with a
1506         state number.
1507
1508 2001-12-10  Akim Demaille  <akim@epita.fr>
1509
1510         Now that states have a complete set of members, the linked list of
1511         shifts is useless: just fill directly the state's shifts member.
1512
1513         * src/state.h (shifts): Remove the `next' member.
1514         * src/LR0.c (first_state, last_state): Remove.
1515         Adjust the callers.
1516         (augment_automaton): Don't look for the shifts that must be added
1517         a shift on EOF: it is those of the state we looked for!  But now,
1518         since shifts are attached, it is no longer needed to looking
1519         merely by its id: its number.
1520
1521 2001-12-10  Akim Demaille  <akim@epita.fr>
1522
1523         * src/LR0.c (augment_automaton): Better variable locality.
1524         Remove an impossible branch: if there is a state corresponding to
1525         the start symbol being shifted, then there is shift for the start
1526         symbol from the initial state.
1527
1528 2001-12-10  Akim Demaille  <akim@epita.fr>
1529
1530         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1531         only when appropriate: when insert_start_shifting_state' is not
1532         invoked.
1533         * tests/regression.at (Rule Line Numbers): Adjust.
1534
1535 2001-12-10  Akim Demaille  <akim@epita.fr>
1536
1537         * src/LR0.c (augment_automaton): Now that all states have shifts,
1538         merge the two cases addition shifts to the initial state.
1539
1540 2001-12-10  Akim Demaille  <akim@epita.fr>
1541
1542         * src/lalr.c (set_state_table): Move to...
1543         * src/LR0.c: here.
1544         * src/lalr.c (lalr): Don't call it...
1545         * src/LR0.c (generate_states): do it.
1546         * src/LR0.h (first_state): Remove, only the table is used.
1547
1548 2001-12-10  Akim Demaille  <akim@epita.fr>
1549
1550         * src/LR0.h (first_shift, first_reduction): Remove.
1551         * src/lalr.c: Don't use first_shift: find shifts through the
1552         states.
1553
1554 2001-12-10  Akim Demaille  <akim@epita.fr>
1555
1556         * src/LR0.c: Attach shifts to states as soon as they are
1557         computed.
1558         * src/lalr.c (set_state_table): Instead of assigning shifts to
1559         state, just assert that the mapping was properly done.
1560
1561 2001-12-10  Akim Demaille  <akim@epita.fr>
1562
1563         * src/LR0.c (insert_start_shift): Rename as...
1564         (insert_start_shifting_state): this.
1565         (insert_eof_shifting_state, insert_accepting_state): New.
1566         (augment_automaton): Adjust.
1567         Better locality of the variables.
1568         When looking if the start_symbol is shifted from the initial
1569         state, using `while (... symbol != start_symbol ...)' sounds
1570         better than `while (... symbol < start_symbol ...)': If fail
1571         to see how the order between symbols could be relevant!
1572
1573 2001-12-10  Akim Demaille  <akim@epita.fr>
1574
1575         * src/getargs.h: Don't declare `spec_name_prefix' and
1576         `spec_file_prefix', declared by src/files.h.
1577         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1578         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1579         * src/output.c (prepare): Adjust.
1580         * src/reader.c (symbols_output): Likewise.
1581         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1582
1583 2001-12-10  Akim Demaille  <akim@epita.fr>
1584
1585         * src/muscle_tab.c (muscle_init): NULL is a better default than
1586         `"0"'.
1587
1588 2001-12-10  Akim Demaille  <akim@epita.fr>
1589
1590         * src/reader.c (reader): Calling symbols_output once is enough.
1591
1592 2001-12-10  Akim Demaille  <akim@epita.fr>
1593
1594         Now that states have a complete set of members, the linked list of
1595         reductions is useless: just fill directly the state's reductions
1596         member.
1597
1598         * src/state.h (struct reductions): Remove member `number' and
1599         `next'.
1600         * src/LR0.c (first_reduction, last_reduction): Remove.
1601         (save_reductions): Don't link the new reductions, store them in
1602         this_state.
1603         * src/lalr.c (set_state_table): No need to attach reductions to
1604         states, it's already done.
1605         * src/output.c (output_actions): No longer free the shifts, then
1606         the reductions, then the states: free all the states and their
1607         members.
1608
1609 2001-12-10  Akim Demaille  <akim@epita.fr>
1610
1611         * src/options.c (OPTN, DRTV, BOTH): New.
1612         (option_table): Use them.
1613
1614         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1615         the job of system.h.
1616         * src/options.c: Don't include stdio.h and xalloc.h for the same
1617         reasons.
1618
1619 2001-12-10  Akim Demaille  <akim@epita.fr>
1620
1621         * src/output.c (output, prepare): Make sure the values of the
1622         muscles `action' and `prologue' are 0-terminated.
1623
1624 2001-12-10  Akim Demaille  <akim@epita.fr>
1625
1626         Clean up GCC warnings.
1627
1628         * src/reader.c (copy_action): `buf' is not used.
1629         (parse_skel_decl): Be static.
1630         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1631         * src/options.h (create_long_option_table): Have a real prototype.
1632         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1633         (hash_delete_at): Return const void *.
1634         Adjust casts to preserve the const.
1635
1636 2001-12-10  Akim Demaille  <akim@epita.fr>
1637
1638         * configure.in: Require 2.52g.
1639         M4 is not needed, but AUTOM4TE is.
1640         * m4/m4.m4: Remove.
1641         * tests/Makefile.am: Adjust.
1642
1643 2001-12-10  Akim Demaille  <akim@epita.fr>
1644
1645         One structure for states is enough, even though theoretically
1646         there are LR(0) states and LALR(1) states.
1647
1648         * src/lalr.h (state_t): Remove.
1649         (state_table): Be state_t **, not state_t *.
1650         * src/state.h (core, CORE_ALLOC): Rename as...
1651         (state_t, STATE_ALLOC): this.
1652         Add the LALR(1) members: shifts, reductions, errs.
1653         * src/LR0.c (state_table): Rename as...
1654         (state_hash): this, to avoid name clashes with the global
1655         `state_table'.
1656         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1657         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

1659 2001-12-10  Akim Demaille  <akim@epita.fr>
1660
1661         Bison dumps core on bash.y.
1662         Reported by Pascal Bart.
1663
1664         * src/warshall.c (bitmatrix_print): New.
1665         (TC): Use it.
1666         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1667         j must be the outer loop.
1668         * tests/regression.at (Broken Closure): New.
1669
1670 2001-12-05  Akim Demaille  <akim@epita.fr>
1671
1672         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1673         its argument.
1674         Reported by Peter Hámorský.
1675
1676 2001-12-05  Akim Demaille  <akim@epita.fr>
1677
1678         * src/conflicts.c (err_table): Remove.
1679         (resolve_sr_conflict): Adjust.
1680         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1681         Rename as...
1682         (state_t.reductions, state_t.shifts): this.
1683
1684 2001-12-05  Akim Demaille  <akim@epita.fr>
1685
1686         * src/reduce.c (reduce_grammar_tables): No longer disable the
1687         removal of useless rules via CPP but via `if (0)', so that the
1688         compiler still check the code is valid.
1689         For instance, it should have noticed `rline' no longer exists: use
1690         the `line' member of rule_t.
1691         * src/gram.c (dummy, rline): Remove, unused.
1692
1693 2001-12-05  Akim Demaille  <akim@epita.fr>
1694
1695         * src/output.c (pack_vector): Use assert, not berror.
1696         * src/main.c (berror): Remove, unused.
1697
1698 2001-12-05  Akim Demaille  <akim@epita.fr>
1699
1700         New experimental feature: if --verbose --trace output all the
1701         items of a state, not only its kernel.
1702
1703         * src/print.c (print_core): If `trace_flag', then invoke closure
1704         before outputting the items of the state (print_core is no longer
1705         a correct name them).
1706         (print_results): Invoke new_closure/free_closure if needed.
1707
1708 2001-12-05  Akim Demaille  <akim@epita.fr>
1709
1710         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1711         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1712         (nitemset): for consistency with the rest of the project.
1713
1714 2001-12-05  Akim Demaille  <akim@epita.fr>
1715
1716         * src/closure.c (print_closure): Improve.
1717         (closure): Use it for printing input and output.
1718
1719 2001-12-05  Akim Demaille  <akim@epita.fr>
1720
1721         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1722         indexed by nonterminals.
1723
1724 2001-12-05  Akim Demaille  <akim@epita.fr>
1725
1726         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1727         what it was!).
1728         * src/warshall.h: Remove accidental duplication of the content.
1729
1730 2001-12-05  Akim Demaille  <akim@epita.fr>
1731

1742 2001-12-05  Akim Demaille  <akim@epita.fr>
1743
1744         * src/output.c (action_row): De-obfuscate
1745         using the good o' techniques: arrays not pointers, variable
1746         locality, BITISSET, RESETBIT etc.
1747
1748 2001-12-05  Akim Demaille  <akim@epita.fr>
1749
1750         Pessimize the code to simplify it: from now on, all the states
1751         have a valid SHIFTS, which NSHIFTS is possibly 0.
1752
1753         * src/LR0.c (shifts_new): Be global and move to..
1754         * src/state.c, src/state.h: here.
1755         * src/conflicts, src/lalr.c, src/output.c, src/print.c,

1759
1760         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1761         * src/conflicts.c: Use it.
1762         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1763         incorrectly ``simplified''.
1764
1765 2001-12-05  Akim Demaille  <akim@epita.fr>
1766
1767         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate

1769         locality, BITISSET, RESETBIT etc.
1770

1777
1778         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1779         (print_reductions): De-obfuscate using the good o' techniques:
1780         arrays not pointers, variable locality, BITISSET.
1781
1782 2001-12-05  Akim Demaille  <akim@epita.fr>
1783
1784         * src/conflicts.c (print_reductions): Arrays, not pointers.

1817         Use arrays instead of pointers.
1818
1819 2001-12-05  Akim Demaille  <akim@epita.fr>
1820
1821         * src/lalr.c (maxrhs): Move to...
1822         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1823         * src/lalr.c (build_relations): Adjust.
1824
1825 2001-12-05  Akim Demaille  <akim@epita.fr>
1826
1827         * src/lalr.c (transpose): Free the memory allocated to the
1828         argument, as it is replaced by the results by the unique caller.
1829         (build_relations): Merely invoke transpose: it handles the memory
1830         deallocation.
1831         Improve variable locality.
1832         Avoid variables used as mere abbreviations.
1833         (compute_lookaheads): Use arrays instead of pointers.
1834
1835 2001-12-05  Akim Demaille  <akim@epita.fr>
1836
1837         * src/lalr.c (initialize_F): Improve variable locality.
1838         Avoid variables used as mere abbreviations.
1839
1840 2001-12-05  Akim Demaille  <akim@epita.fr>
1841
1842         * src/derives.c (print_derives): Display the ruleno.
1843         * src/lalr.c (initialize_F, transpose): Better variable locality
1844         to improve readability.
1845         Avoid variables used as mere abbreviations.
1846
1847 2001-12-05  Akim Demaille  <akim@epita.fr>
1848
1849         * src/lalr.c (traverse): Use arrays instead of pointers.
1850
1851 2001-12-05  Akim Demaille  <akim@epita.fr>
1852
1853         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1854         the handling of squeue.
1855         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1856
1857 2001-12-05  Akim Demaille  <akim@epita.fr>
1858
1859         Because useless nonterminals are now kept alive (instead of being
1860         `destroyed'), we now sometimes examine them, and store information
1861         related to them.  Hence we need to know their number, and adjust
1862         memory allocations.
1863
1864         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1865         static.
1866         * src/LR0.c (allocate_itemsets): The memory allocated to
1867         `symbol_count' was used for two different purpose: once to count
1868         the number of occurrences of each symbol, and later reassigned to
1869         `shift_symbol', containing the symbol that can be shifted from a
1870         given state.
1871         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1872         only, and...
1873         (new_itemsets): Allocate `shift_symbol' here.
1874         (allocate_itemsets): symbol_count includes useless nonterminals.
1875         Make room for them.
1876         (free_storage): Use `free', not `XFREE', for pointers that cannot
1877         be null.
1878
1879 2001-12-05  Akim Demaille  <akim@epita.fr>
1880
1881         * src/nullable.c (set_nullable): Deobfuscate the handling of
1882         ritem.
1883         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1884
1885 2001-12-05  Akim Demaille  <akim@epita.fr>
1886
1887         * src/gram.c, src/gram.h (ritem_print): New.
1888         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1889         (This useless function was defined only to work around VMS linkers
1890         that can't handle compilation units with variables only).
1891         * src/reduce.c (dump_grammar): Use it to trace the construction of
1892         ritem.
1893
1894 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1895
1896         * src/bison.simple (union yyalloc): Change member names
1897         to be the same as the stack names.
1898         (yyparse): yyptr is now union yyalloc *, not char *.
1899         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1900         and may generate better code on some machines.
1901         (yystpcpy): Use prototype if __STDC__ is defined, not just
1902         if __cplusplus is defined.
1903
1904 2001-11-30  Akim Demaille  <akim@epita.fr>
1905
1906         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1907         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1908         Gettext doesn't compile cleanly, and dies with -Werror.
1909         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1910         Include WARNING_CFLAGS here.
1911         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1912         before being defined.
1913
1914 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1915
1916         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1917         First arg is int, not unsigned.
1918         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1919         (SIZE_MAX, UINT_MAX): New macros.
1920         (quotearg_n_options): Abort if N is negative.
1921         Avoid overflow check on hosts where size_t is 64 bits and int
1922         is 32 bits, as overflow is impossible there.
1923         Fix off-by-one typo that caused unnecessary reallocation.
1924
1925 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1926
1927         Name space cleanup in generated parser.
1928
1929         * doc/bison.texinfo (Bison Parser): Discuss system headers
1930         and their effect on the user name space.
1931
1932         * src/bison.simple:
1933         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1934         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1935         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1936
1937         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1938         on user names when possible.
1939
1940         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1941         Simplify test for whather <alloca.h> exists.
1942
1943         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1944
1945         (<stdio.h>): Include if YYDEBUG.
1946
1947         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1948         ! defined (yyoverflow) && ! defined (yymemcpy).
1949
1950         (yymemcpy, yyparse): Rename local variables as needed so that
1951         they all begin with 'yy'.
1952
1953         (yystrlen, yystpcpy): New functions.
1954
1955         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1956         All uses changed.
1957
1958         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1959         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1960         and YYSTACK_FREE instead of malloc and free.
1961
1962 2001-11-30  Akim Demaille  <akim@epita.fr>
1963
1964         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

1973
1974         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1975         if body instead of `;' to pacify GCC's warnings.
1976
1977 2001-11-30  Akim Demaille  <akim@epita.fr>
1978
1979         Instead of mapping the LHS of unused rules to -1, keep the LHS
1980         valid, but flag the rules as invalid.
1981
1982         * src/gram.h (rule_t): `useful' is a new member.
1983         * src/print.c (print_grammar): Adjust.

1986         * src/reduce.c (reduce_grammar_tables): Likewise.

1997
1998         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1999         useless nonterminals, move them at the end of the symbol arrays.

2001         * tests/reduce.at (Useless Nonterminals): Adjust.
2002

2006         (nonterminals_reduce): New, extracted from...

2015         New macros.
2016         (union yyalloc): New type.
2017         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
2018         an arbitrary restriction on hosts where size_t is wider than int.
2019
2020         (yyparse): Don't dump core if alloca or malloc fails; instead, report
2021         a parser stack overflow.  Allocate just one block of memory for all
2022         three stacks, instead of allocating three blocks; this typically is
2023         faster and reduces fragmentation.
2024
2025         Do not limit the number of items in the stack to a value that fits
2026         in 'int', as this is an arbitrary limit on hosts with 64-bit
2027         size_t and 32-bit int.
2028
2029 2001-11-29  Marc Autret  <autret_m@epita.fr>

2050         * src/options.c (option_table): 'error-verbose' is now seen as simple
2051         percent option.

2058         option.
2059
2060 2001-11-28  Marc Autret  <autret_m@epita.fr>
2061
2062         * src/bison.simple: Adjust muscle names.
2063         * src/muscle_tab.c (muscle_init): Also rename the muscles.

2078
2079         * src/closure.c (closure): `b' and `ruleno' denote the same value:
2080         keep ruleno only.
2081
2082 2001-11-28  Akim Demaille  <akim@epita.fr>
2083
2084         * src/closure.c (closure): Instead of looping over word in array
2085         then bits in words, loop over bits in array.
2086
2087 2001-11-28  Akim Demaille  <akim@epita.fr>
2088
2089         * src/closure.c (closure): No longer optimize the special case
2090         where all the bits of `ruleset[r]' are set to 0, to make the code
2091         clearer.
2092

2094

2110         * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

2115
2116         * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

2484         arg_offset.
2485         arg is const.

3456         bound to true.
3457         (read_declarations): Add case for macro definition.
3458         (copy_identifier): New.
3459         (parse_macro_decl): Read macro identifiers using copy_identifier

3494         with something new. Skeletons are now processed character by character

3496         first step in making Bison's output process (a lot) more flexible.
3497         (output_parser): Use the macro table.

3841         making this decision.  This is the only way out for portability
3842         issues in Bison, it would mean way too much duplicate effort to
3843         import in Bison features implemented in 2.49c since 2.13.

3877         Since we now use obstacks, more % directives can be enabled.
3878
3879         * src/lex.c (percent_table): Also accept `%yacc',
3880         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3881         `%debug'.
3882         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3883         instead of returning a token.
3884         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3885         * src/reader.c (read_declarations): Adjust.
3886         * src/files.c (open_files): Don't call `compute_base_names', don't

3888         *in* the input file now.
3889         (output_files): Do it here.
3890         * src/output.c (output_headers): Document the fact that this patch

3916         FILE * parameters.
3917
3918 2000-12-20  Akim Demaille  <akim@epita.fr>
3919
3920         * src/files.c (open_files): Actually the `.output' file is based
3921         on the short_base_name, not base_name.
3922         * tests/suite.at (Checking output file names): Adjust.
3923
3924 2000-12-20  Akim Demaille  <akim@epita.fr>

3951         (base_names): Eve out from open_files.
3952         Try to simplify the rather hairy computation of base_name and
3953         short_base_name.

3955         * tests/suite.at (Checking output file names): New test.

3972
3973 2000-12-19  Akim Demaille  <akim@epita.fr>
3974
3975         Let the handling of the skeleton files be local to the procedures

3994
3995         * src/files.c (open_files): Yipee!  We no longer need all the code

4027         * lib/obstack.h: Formatting changes.
4028         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
4029         prevents type checking.
4030         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
4031         cast the value to (void *): assigning a `foo *' to a `void *'
4032         variable is valid.
4033         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
4034         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

4069
4070 2000-11-07  Akim Demaille  <akim@epita.fr>
4071
4072         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

4082         `address' for consistency.  Qualify it `const'.

4094 2000-11-03  Akim Demaille  <akim@epita.fr>

4097

4113         Use `obstack_save'.
4114         * src/main.c (main): Don't use `atexit' to register `done', since
4115         it no longer has to remove tmp files, just call `output_files'
4116         when there are no errors.
4117
4118 2000-11-02  Akim Demaille  <akim@epita.fr>

4191         (copy_guard): Adjust.

4218
4219 2000-10-04  Akim Demaille  <akim@epita.fr>
4220
4221         When a literal string is used to define two different tokens,
4222         `bison -v' segfaults.
4223         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4224
4225         * tests/regression.m4: New file.
4226         Include the core of the sample provided by Piotr Gackiewicz.

4231
4232         * src/reader.c (parse_expect_decl): Keep `count' within the size

4236 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4237
4238         * bison.s1 (yyparse): Assign the default value
4239         unconditionally, to avoid a GCC warning and make the parser a
4240         tad smaller.
4241
4242 2000-10-02  Akim Demaille  <akim@epita.fr>
4243

4248
4249         * src/derives.c, src/print.c, src/reduce.c: To ease the

4251
4252 2000-10-02  Akim Demaille  <akim@epita.fr>
4253
4254         The location tracking mechanism is precious for parse error
4255         messages.  Nevertheless, it is enabled only when `@n' is used in
4256         the grammar, which is a different issue (you can use it in error
4257         message, but not in the grammar per se).  Therefore, there should
4258         be another means to enable it.
4259
4260         * src/getargs.c (getargs): Support `--locations'.
4261         (usage): Report it.
4262         * src/getargs.h (locationsflag): Export it.
4263         * src/lex.c (percent_table): Support `%locations'.
4264         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4265         with `locationsflag'.
4266         * doc/bison.texinfo: Document `--locations' and `%locations'.
4267         Sort the options.
4268         * tests/calc.m4: Test it.
4269
4270         For regularity of the names, replace each
4271         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4272         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4273         In addition replace each `flag' with `_flag'.
4274
4275 2000-10-02  Akim Demaille  <akim@epita.fr>
4276
4277         Also test parse error messages, including with YYERROR_VERBOSE.
4278
4279         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4280         associative).
4281         Use it to check the computations.
4282         Use it to check `nonassoc' is honored.
4283         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4284         `--yyerror-verbose'.
4285         (_AT_CHECK_CALC): Adjust to this option.
4286         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4287
4288 2000-10-02  Akim Demaille  <akim@epita.fr>
4289
4290         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4291         the latter demonstrates a flaw in the handling of non debugging
4292         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4293         was used in order to simplify:
4294
4295         #if YYDEBUG
4296         if (yydebug)
4297         {
4298         ...
4299         }
4300         #endif
4301
4302         into
4303
4304         if (yydebug)
4305         {
4306         ...
4307         }
4308
4309         unfortunately this leads to a CPP conflict when
4310         `--name-prefix=foo' is used since it produces `#define yydebug
4311         foodebug'.
4312
4313         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.

4328         of its line.
4329         New variable, `number_of_dollar_signs', to check there's exactly
4330         one `$' in the parser skeleton.
4331
4332 2000-10-02  Akim Demaille  <akim@epita.fr>
4333

4335         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4336         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4337         instead of strlen + xmalloc + strcpy.
4338         * src/symtab.c (copys): Remove, use xstrdup instead.
4339
4340 2000-10-02  Akim Demaille  <akim@epita.fr>
4341
4342         * src/gram.h (associativity): New enum type which replaces the
4343         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4344         `right_assoc', `left_assoc' and `non_assoc'.
4345         Adjust all dependencies.
4346         * src/reader.c: Formatting changes.

4349         * src/symtab.h (symbol_class): New enum type which replaces the
4350         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with

4358
4359 2000-10-02  Akim Demaille  <akim@epita.fr>
4360
4361         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4362         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4363         difficult and introduced a lot of core dump.  It turns out that
4364         Bison used an implementation of `xmalloc' based on `calloc', and
4365         at various places it does depend upon the initialization to 0.  I
4366         have not tried to isolate the pertinent places, and all the former
4367         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4368         someone should address this issue.
4369
4370         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4371         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4384
4385         * src/state.h (nstates, final_state, first_state, first_shift)

4464
4465         * src/output.c (token_actions): Introduce a temporary array,

4470
4471         `user_toknums' is output as a `short[]' in `output.c', while it is
4472         defined as a `int[]' in `reader.c'.  For consistency with the
4473         other output tables, `user_toknums' is now defined as a table of
4474         shorts.
4475
4476         * src/reader.c (user_toknums): Be a short table instead of an int
4477         table.

4489         order to get rid of the `static' prototypes.
4490         No longer use `register'.
4491         * src/output.h: New file.
4492         Propagate its inclusion in files explicitly prototyping functions
4493         from output.c.

4517         * src/system.h: Define PARAMS.
4518         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

4520         definitions in config.h.

4682         the file name, not the whole `#line LINE FILE'.
4683
4684 2000-03-17  Akim Demaille  <akim@epita.fr>
4685
4686         On syntax errors, report the token on which we choked.

4708         copy_comment.  Removed now unused `match', `ended',
4709         `cplus_comment'.
4710         (copy_comment, copy_string): Moved, to be visible from
4711         copy_definition.

4737
4738         Change the handling of @s so that they behave exactly like $s.
4739         There is now a pseudo variable @$ (readble and writable), location
4740         of the lhs of the rule (by default ranging from the location of
4741         the first symbol of the rhs, to the location of the last symbol,
4742         or, if the rhs is empty, YYLLOC).
4743
4744         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4745         yyval.
4746         (yyparse): When providing a default semantic action, provide a
4747         default location action.
4748         (after the $): No longer change `*YYLSP', just stack YYLOC the
4749         same way you stack YYVAL.
4750         * src/reader.c (read_declarations): Use warns.
4751         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4752         (copy_action, case '@'): Likewise.
4753         Use a standard error message, to save useless work from
4754         translators.
4755
4756 2000-03-17  Akim Demaille  <akim@epita.fr>

4775
4776         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4777         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4778         One `#if YYDEBUG' remains, since it uses variables which are
4779         defined only if `YYDEBUG != 0'.
4780
4781 2000-03-16  Akim Demaille  <akim@epita.fr>

4805         handled via src/Makefile.am.

4807         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4808         autoheader.

4813         the proper line number and file name.
4814         (DEFS): Propagate the location of bison library files and of the
4815         locale files.
4816         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4817         builddir.
4818         * acinclude.m4: Remove, replaced by the directory m4.
4819         * m4/Makefile.am (EXTRA_DIST): New variable.
4820         * m4/gettext.m4: New file, from the fileutils.

5452         (readgram): Use `#if 0' around code that accepted %command
5453         inside grammar rules:  The documentation doesn't allow it,
5454         and it will fail since the %command processors scan for the next %.
5455         (parse_token_decl):  Extended the %token
5456         declaration to allow a multi-character symbol as an alias.

5465         (get_type_name, copy_guard, copy_action, readgram)
5466         (get_type, packsymbols):  Revised most error messages.
5467         Changed `fatal' to `warnxxx' to avoid aborting for error.
5468         Revised and use multiple warnxxx functions to avoid using VARARGS1.
5469         (read_declarations): Improve the error message for
5470         an invalid character.  Do not abort.
5471         (read_declarations, copy_guard, copy_action): Use
5472         printable_version to avoid unprintable characters in printed output.
5473         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
5474         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
5475         Allow the type of a non-terminal can be given
5476         more than once, as long as all specifications give the same type.
5477
5478         * src/output.c:

5481         Implement toknumflag variable.
5482         (output): Call reader_output_yylsp to output LTYPESTR.
5483
5484         * src/main.c (main):
5485          If reader sees an error, don't process the grammar.
5486         (fatals): Updated to not use VARARGS1.
5487         (printable_version, int_to_string, warn, warni, warns, warnss)
5488         (warnsss): New error reporting functions.  Avoid abort for error.
5489
5490         * src/lex.h:
5491         Added THONG and NOOP for alias processing.
5492         Added SETOPT for the new code that allows setting options with %flags.

5500         (literalchar, lex, parse_percent_token): Made tokenbuffer
5501         always contain the token.  This includes growing the token
5502         buffer while reading an integer.

5504         (parse_percent_token): Added % declarations as another
5505         way to specify the flags -n, -l, and -r.  Also added hooks for
5506         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
5507         major changes to files.c.
5508         (lex) Retain in the incoming stream a character following
5509         an incorrect '/'.
5510         (skip_white_space, lex):  Revised most error messages
5511         and changed fatal to warn to avoid aborting.
5512         (percent_table):  Added %thong declarations.
