   2
   3         * src/gram.c (nitems, nrules, nsyms, ntokens, nvars, nritems)

   5         (error_token_number): Initialize.
   6         * src/reader.c (grammar, start_flag, startval, typed, lastprec):

  10
  11 2002-04-07  Akim Demaille  <akim@epita.fr>
  12
  13         * src/gram.h (rule_s): prec and precsym are now pointers
  14         to the bucket giving the priority/associativity.
  15         Member `associativity' removed: useless.
  16         * src/reduce.c, src/conflicts.c: Adjust.
  17
  18 2002-04-07  Akim Demaille  <akim@epita.fr>
  19
  20         * src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c:
  21         Properly escape the symbols' TAG when outputting them.
  22
  23 2002-04-07  Akim Demaille  <akim@epita.fr>
  24
  25         * src/lalr.h (LA): Is a bitsetv, not bitset*.
  26
  27

  29
  30         * src/lalr.h, src/lalr.c (LAruleno): Replace with...
  31         (LArule): this, which is an array to rule_t*.

  33
  34
  35 2002-04-07  Akim Demaille  <akim@epita.fr>
  36
  37         * src/gram.h (rule_t): Rename `number' as `user_number'.
  38         `number' is a new member.
  39         Adjust dependencies.
  40         * src/reduce.c (reduce_grammar_tables): Renumber rule_t.number.
  41
  42 2002-04-07  Akim Demaille  <akim@epita.fr>
  43
  44         As a result of the previous patch, it is no longer needed
  45         to reorder ritem itself.
  46
  47         * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
  48
  49 2002-04-07  Akim Demaille  <akim@epita.fr>
  50
  51         Be sure never to walk through RITEMS, but use only data related to
  52         the rules themselves. RITEMS should be banished.
  53
  54         * src/output.c (output_token_translations): Rename as...
  55         (prepare_tokens): this.
  56         In addition to `translate', prepare the muscles `tname' and
  57         `toknum', which were handled by...
  58         (output_rule_data): this.
  59         Remove, and move the remainder of its outputs into...
  60         (prepare_rules): this new routines, which also merges content from
  61         (output_gram): this.
  62         (prepare_rules): Be sure never to walk through RITEMS.
  63         (output_stos): Rename as...
  64         (prepare_stos): this.

  67
  68 2002-04-07  Akim Demaille  <akim@epita.fr>
  69
  70         * src/LR0.c (new_state): Display `nstates' as the name of the
  71         newly created state.
  72         Adjust to initialize first_state and last_state if needed.
  73         Be sure to distinguish the initial from the final state.
  74         (new_states): Create the itemset of the initial state, and use
  75         new_state.
  76         * src/closure.c (closure): Now that the initial state has its
  77         items properly set, there is no need for a special case when
  78         creating `ruleset'.
  79
  80         As a result, now the rule 0, reducing to $axiom, is visible in the
  81         outputs.  Adjust the test suite.
  82
  83         * tests/conflicts.at (Solved SR Conflicts)
  84         (Unresolved SR Conflicts): Adjust.

  91         the RHS of the rules.
  92         * src/output.c (output_gram): Likewise.
  93
  94 2002-04-07  Akim Demaille  <akim@epita.fr>
  95
  96         * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's
  97         bucket.
  98         Adjust all dependencies.
  99         * src/reduce.c (nonterminals_reduce): Don't forget to renumber the
 100         `number' of the buckets too.
 101         * src/gram.h: Include `symtab.h'.
 102         (associativity): Move to...
 103         * src/symtab.h: here.
 104         No longer include `gram.h'.
 105
 106
 107 2002-04-07  Akim Demaille  <akim@epita.fr>
 108
 109         * src/gram.h, src/gram.c (rules_rhs_length): New.
 110         (ritem_longest_rhs): Use it.
 111         * src/gram.h (rule_t): `number' is a new member.

 113         * src/reduce.c (reduce_grammar_tables): Move the useless rules at
 114         the end of `rules', and count them out of `nrules'.
 115         (reduce_output, dump_grammar): Adjust.
 116         * src/print.c (print_grammar): It is no longer needed to check for
 117         the usefulness of a rule, as useless rules are beyond `nrules + 1'.
 118         * tests/reduce.at (Reduced Automaton): New test.
 119
 120 2002-04-07  Akim Demaille  <akim@epita.fr>
 121
 122         * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
 123         lacking `+ 1' to nrules, Bison reported as useless a token if it
 124         was used solely to set the precedence of the last rule...
 125
 126 2002-04-07  Akim Demaille  <akim@epita.fr>
 127
 128         * data/bison.c++, data/bison.simple: Don't output the current file
 129         name in #line, to avoid useless diffs between two identical
 130         outputs under different names.
 131
 132 2002-04-07  Akim Demaille  <akim@epita.fr>
 133
 134         * src/closure.c, src/print.c, src/reader.c, src/reduce.c:
 135         Normalize loops to using `< nrules + 1', not `<= nrules'.
 136
 137 2002-04-07  Akim Demaille  <akim@epita.fr>
 138
 139         * TODO: Update.

 375         * lib/bitsetv.h, lib/ebitset.c, lib/ebitset.h, lib/lbitset.c,
 376         * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
 377         * src/closure.c (fderives): Be an array of bitsets.
 378
 379 2002-02-28  Robert Anisko  <robert@lrde.epita.fr>
 380
 381         * data/bison.c++: Merge the two generated headers.  Insert a copyright
 382         notice in each output file.
 383
 384 2002-02-28  Akim Demaille  <akim@epita.fr>
 385
 386         * data/bison.c++: Copy the prologue of bison.simple to fetch
 387         useful M4 definitions, such as b4_header_guard.
 388
 389 2002-02-25  Akim Demaille  <akim@epita.fr>
 390
 391         * src/getargs.c (version): Give the name of the authors, and use a
 392         translator friendly scheme for the bgr
 393         copyright notice.
 394
 395 2002-02-25  Akim Demaille  <akim@epita.fr>
 396
 397         * src/output.c (header_output): Remove, now handled completely via

 401
 402         * m4/m4.m4: New, from CVS Autoconf.
 403         * configure.in: Invoke it.
 404         * src/output.c (output_skeleton): Use its result instead of the
 405         hard coded name.
 406
 407 2002-02-25  Akim Demaille  <akim@epita.fr>
 408
 409         * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from

 419
 420 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 421
 422         Remove the support for C++ namespace cleanliness; it was
 423         causing more problems than it was curing, since it didn't work
 424         properly on some nonstandard C++ compilers.  This can wait
 425         for a proper C++ parser.
 426
 427         * NEWS: Document this.
 428         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
 429         of C++, as it's treated like C now.
 430         * src/bison.simple (YYSTD): Remove.
 431         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
 432         Treat C++ just like Standard C instead of trying to support
 433         namespace cleanliness.
 434
 435 2002-02-14  Akim Demaille  <akim@epita.fr>
 436
 437         * tests/regression.at (else): Adjust to Andreas' change.
 438
 439 2002-02-14  Akim Demaille  <akim@epita.fr>
 440
 441         * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
 442
 443 2002-02-13  Andreas Schwab  <schwab@suse.de>
 444
 445         * src/output.c (output_rule_data): Don't output NULL, it might
 446         not be defined yet.
 447
 448 2002-02-11  Robert Anisko  <robert@lrde.epita.fr>
 449
 450         * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
 451         (Copyright notice): Update.
 452
 453 2002-02-11  Akim Demaille  <akim@epita.fr>
 454
 455         * tests/regression.at (%nonassoc and eof): Don't include
 456         nonportable headers.
 457
 458 2002-02-08  Robert Anisko  <robert@lrde.epita.fr>
 459
 460         * data/bison.c++: Correct error recovery.  Make the user able to
 461         initialize the starting location.
 462
 463 2002-02-07  Akim Demaille  <akim@epita.fr>
 464
 465         * tests/input.at: New.
 466
 467 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 468
 469         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 470         more consistent when naming methods and variables.  Put preprocessor
 471         directives around tables only needed for debugging.
 472
 473 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 474
 475         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
 476         C++ parsers.
 477         (yy::b4_name::parse): Use print_.
 478
 479 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 480
 481         * data/bison.c++ (yy::b4_name::parse): Error recovery is back.

 485         * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
 486         C++ parsers.
 487         (yy::b4_name::parse): Build verbose error messages, and use error_.
 488
 489 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 490
 491         * data/bison.c++: Fix m4 quoting in comments.
 492
 493 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 494
 495         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 496         not expanded by m4.
 497
 498 2002-02-05  Akim Demaille  <akim@epita.fr>
 499
 500         * data/bison.c++: Adjust to the M4 back end.
 501         More is certainly needed.
 502
 503 2002-02-05  Akim Demaille  <akim@epita.fr>
 504
 505         Give a try to M4 as a back end.
 506
 507         * lib/readpipe.c: New, from wdiff.
 508         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
 509         BISON_HAIRY.
 510         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 511         specific values.  Now it is m4 that performs the lookup.
 512         * src/parse-skel.y: Remove.
 513         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 514         * src/output.c (actions_output, guards_output)
 515         (token_definitions_output): No longer keeps track of the output
 516         line number, hence remove the second argument.
 517         (guards_output): Check against the guard member of a rule, not the
 518         action member.
 519         Adjust callers.
 520         (output_skeleton): Don't look for the skeleton location, let m4 do
 521         that.
 522         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 523         file will be used.
 524         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 525         (prepare): Given that for the time being changesyntax is not
 526         usable in M4, rename the muscles using `-' to `_'.
 527         Define `defines_flag', `output_parser_name' and `output_header_name'.
 528         * src/output.h (actions_output, guards_output)
 529         (token_definitions_output): Adjust prototypes.
 530         * src/scan-skel.l: Instead of scanning the skeletons, it now
 531         processes the output of m4: `__oline__' and `#output'.
 532         * data/bison.simple: Adjust to be used by M4(sugar).
 533         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 534         to date.
 535         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 536         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 537         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 538         shamelessly stolen from CVS Autoconf.
 539
 540 2002-02-05  Akim Demaille  <akim@epita.fr>
 541
 542         * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
 543         * configure.in: Check for the declarations of free and malloc.
 544         * src/muscle_tab.c: Adjust.
 545
 546 2002-02-05  Akim Demaille  <akim@epita.fr>
 547
 548         * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
 549         which have no values.
 550
 551 2002-02-05  Akim Demaille  <akim@epita.fr>
 552
 553         * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
 554         * data/: here.
 555
 556 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 557
 558         * src/bison.simple (YYSIZE_T): Do not define merely because
 559         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 560         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 561
 562 2002-01-27  Akim Demaille  <akim@epita.fr>
 563
 564         Fix `%nonassoc and eof'.
 565
 566         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 567         which were not properly copied!  Replace
 568         memcpy (res->errs, src->errs, src->nerrs);
 569         with
 570         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 571         !!!
 572         * tests/regression.at (%nonassoc and eof): Adjust to newest
 573         Autotest: `.' is not in the PATH.
 574
 575 2002-01-27  Akim Demaille  <akim@epita.fr>
 576
 577         * tests/sets.at (AT_EXTRACT_SETS): New.
 578         (Nullable): Use it.
 579         (Firsts): New.
 580
 581 2002-01-26  Akim Demaille  <akim@epita.fr>
 582
 583         * tests/actions.at, tests/calc.at, tests/headers.at,
 584         * tests/torture.at: Adjust to the newest Autotest which no longer
 585         forces `.' in the PATH.
 586
 587 2002-01-25  Akim Demaille  <akim@epita.fr>
 588
 589         * tests/regression.at (%nonassoc and eof): New.
 590         Suggested by Robert Anisko.
 591
 592 2002-01-24  Akim Demaille  <akim@epita.fr>
 593
 594         Bison dumps core when trying to complain about broken input files.
 595         Reported by Cris van Pelt.
 596
 597         * src/lex.c (parse_percent_token): Be sure to set token_buffer.
 598         * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
 599         into...
 600         (Invalid inputs): Strengthen: exercise parse_percent_token.
 601
 602 2002-01-24  Robert Anisko  <robert.anisko@epita.fr>
 603
 604         * src/Makefile.am: Add bison.c++.
 605         * src/bison.c++: New skeleton.
 606
 607 2002-01-21  Paolo Bonzini <bonzini@gnu.org>
 608
 609         * po/it.po: New.
 610
 611 2002-01-21  Kees Zeelenberg  <kzlg@users.sourceforge.net>
 612
 613         * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
 614
 615 2002-01-20  Marc Autret  <marc@gnu.org>
 616
 617         * src/files.c (compute_output_file_names): Fix
 618
 619 2002-01-20  Marc Autret  <marc@gnu.org>
 620
 621         * tests/output.at: New test.
 622         * src/files.c (compute_base_names): Don't map extensions when
 623         the YACC flag is set, use defaults.
 624         Reported by Evgeny Stambulchik.
 625
 626 2002-01-20  Marc Autret  <marc@gnu.org>
 627
 628         * src/system.h: Need to define __attribute__ away for non-GCC
 629         compilers as well (i.e. the vendor C compiler).
 630         Suggested by Albert Chin-A-Young.
 631
 632 2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
 633
 634         * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
 635         canonical definition.
 636         * src/system.h: Use the canonical definition for PARAMS (avoids
 637         a conflict with the macro from lib/hash.h).
 638
 639 2002-01-11  Akim Demaille  <akim@epita.fr>
 640
 641         * configure.in: Use AC_FUNC_STRNLEN.
 642         Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
 643
 644 2002-01-09  Akim Demaille  <akim@epita.fr>
 645
 646         * src/files.c, src/files.h (output_infix): New.
 647         (tab_extension): Remove.
 648         (compute_base_names): Compute the former, drop the latter.
 649         * src/output.c (prepare): Insert the muscles `output-infix', and
 650         `output-suffix'.
 651         * src/parse-skel.y (string, string.1): New.
 652         (section.header): Use it.
 653         (section.yacc): Remove.
 654         (prefix): Remove too.
 655         * src/scan-skel.l: Adjust.
 656         * src/bison.simple, src/bison.hairy: Adjust.
 657
 658 2002-01-09  Akim Demaille  <akim@epita.fr>
 659
 660         * configure.in (WERROR_CFLAGS): Compute it.
 661         * src/Makefile.am (CFLAGS): Pass it.
 662         * tests/atlocal.in (CFLAGS): Idem.
 663         * src/files.c: Fix a few warnings.
 664         (get_extension_index): Remove, unused.
 665
 666 2002-01-08  Akim Demaille  <akim@epita.fr>
 667
 668         * src/getargs.c (AS_FILE_NAME): New.
 669         (getargs): Use it to convert DOSish file names.
 670         * src/files.c (base_name): Rename as full_base_name to avoid
 671         clashes with `base_name ()'.
 672         (filename_split): New.
 673         (compute_base_names): N-th rewrite, using filename_split.
 674
 675 2002-01-08  Akim Demaille  <akim@epita.fr>
 676
 677         * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
 678         New, stolen from the Fileutils 4.1.
 679         * lib/Makefile.am (libbison_a_SOURCES): Adjust.
 680         * configure.in: Check for the presence of memrchr, and of its
 681         prototype.
 682
 683 2002-01-07  Tim Van Holder  <tim.van.holder@pandora.be>
 684
 685         * lib/hash.h (__P): Added definition for this macro.
 686         * src/Makefile.am: Add parse-skel.c and scan-skel.c to
 687         BUILT_SOURCES, to ensure they are generated first.
 688         * src/parse-skel.y: Use YYERROR_VERBOSE instead of
 689         %error-verbose to allow bootstrapping with bison 1.30x.
 690
 691 2002-01-06  Akim Demaille  <akim@epita.fr>
 692
 693         * src/reader.c (parse_braces): Don't fetch the next char, the
 694         convention is to fetch on entry.
 695         * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
 696         'switch' without a following semicolon.
 697         * tests/regression.at (braces parsing): New.
 698
 699 2002-01-06  Akim Demaille  <akim@epita.fr>
 700
 701         Bison is dead wrong in its RR conflict reports.
 702
 703         * tests/torture.at (GNU Cim Grammar): New.
 704         * src/conflicts.c (count_rr_conflicts): Fix.
 705
 706 2002-01-06  Akim Demaille  <akim@epita.fr>
 707
 708         Creating package.m4 from configure.ac causes too many problems.
 709
 710         * tests/Makefile.am (package.m4): Create it by hand,
 711         AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 712
 713 2002-01-06  Akim Demaille  <akim@epita.fr>
 714
 715         * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
 716         skeleton.h.
 717
 718 2002-01-04  Paul Eggert  <eggert@twinsun.com>
 719
 720         * doc/bison.texinfo (Debugging):
 721         Remove YYSTDERR; it's no longer defined or used.
 722         Also, s/cstdio.h/cstdio/.
 723
 724 2002-01-03  Akim Demaille  <akim@epita.fr>
 725
 726         * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
 727
 728 2002-01-03  Akim Demaille  <akim@epita.fr>
 729
 730         * src/parse-skel.y (process_skeleton): Don't bind the parser's
 731         tracing code to --trace, wait for a better --trace option, with
 732         args.
 733
 734 2002-01-03  Akim Demaille  <akim@epita.fr>
 735
 736         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 737         The ISO C++ standard is extremely clear about it: stderr is
 738         considered a macro, not a regular symbol (see table 94 `Header
 739         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 740         Therefore std:: does not apply to it.  It still does with fprintf.
 741         Also, s/cstdio.h/cstdio/.
 742
 743 2002-01-03  Akim Demaille  <akim@epita.fr>
 744
 745         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 746         for non system headers.

 750         Equip the skeleton chain with location tracking, runtime trace,
 751         pure parser and scanner.
 752
 753         * src/parse-skel.y: Request a pure parser, locations, and prefix
 754         renaming.
 755         (%union): Having several members with the same type does not help
 756         type mismatches, simplify.
 757         (YYPRINT, yyprint): New.
 758         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 759         (skel_error): this.
 760         Handle locations.
 761         * src/scan-skel.l: Adjust to these changes.
 762         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 763         (LOCATION_PRINT, skel_control_t): New.
 764
 765 2001-12-30  Akim Demaille  <akim@epita.fr>
 766
 767         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 768         replace `gb' with BLANKS.
 769         * src/scan-skel.l: Adjust.
 770
 771 2001-12-30  Akim Demaille  <akim@epita.fr>
 772
 773         * src/system.h: We don't need nor want bcopy.
 774         Throw away MS-DOS crap: we don't need getpid.
 775         * configure.in: We don't need strndup.  It was even causing
 776         problems: because Flex includes the headers *before* us,
 777         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 778         not visible.
 779         * lib/xstrndup.c: New.
 780         * src/scan-skel.l: Use it.
 781         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 782         * src/parse-skel.y: Use %directives instead of #defines.
 783
 784 2001-12-30  Akim Demaille  <akim@epita.fr>
 785
 786         * src/skeleton.h: New.
 787         * src/output.c (output_parser, output_master_parser): Remove, dead
 788         code.
 789         * src/output.h (get_lines_number, actions_output, guards_output)
 790         (token_definitions_output): Prototype them.
 791         * src/parse-skel.y: Add the license notice.
 792         Include output.h and skeleton.h.
 793         (process_skeleton): Returns void, and takes a single parameter.
 794         * src/scan-skel.l: Add the license notice.
 795         Include skeleton.h.
 796         Don't use %option yylineno: it seems that then Flex imagines
 797         REJECT has been used, and therefore it won't reallocate its
 798         buffers (which makes no other sense to me than a bug).  It results
 799         in warnings for `unused: yy_flex_realloc'.
 800
 801 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 802
 803         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 804         (MUSCLE_INSERT_PREFIX): ...to there.
 805         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 806         (MUSCLE_INSERT_PREFIX): Move from here...
 807
 808         * src/bison.hairy: Add a section directive.  Put braces around muscle
 809         names.  This parser skeleton is still broken, but Bison should not
 810         choke on a bad muscle 'syntax'.
 811         * src/bison.simple: Add a section directive.  Put braces around muscle
 812         names.
 813
 814         * src/files.h (strsuffix, stringappend): Add declarations.
 815         (tab_extension): Add declaration.
 816         (short_base_name): Add declaration.
 817
 818         * src/files.c (strsuffix, stringappend): No longer static.  These
 819         functions are used in the skeleton parser.
 820         (tab_extension): New.
 821         (compute_base_names): Use the computations done in this function
 822         to guess if the generated parsers should have '.tab' in their
 823         names.
 824         (short_base_name): No longer static.
 825
 826         * src/output.c (output_skeleton): New.
 827         (output): Disable call to output_master_parser, and give a try to
 828         a new skeleton handling system.
 829         (guards_output, actions_output): No longer static.
 830         (token_definitions_output, get_lines_number): No longer static.
 831
 832         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 833
 834         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 835         parse-skel.y.
 836
 837         * src/parse-skel.y: New file.
 838         * src/scan-skel.l: New file.
 839
 840 2001-12-29  Akim Demaille  <akim@epita.fr>
 841
 842         %name-prefix is broken.
 843
 844         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 845         Adjust all dependencies.
 846         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 847         %name-prefix.
 848
 849         Renaming yylval but not yylloc is not consistent.  Now we do.
 850
 851         * src/bison.simple: Prefix yylloc if used.
 852         * doc/bison.texinfo (Decl Summary): Document that.
 853
 854 2001-12-29  Akim Demaille  <akim@epita.fr>
 855
 856         * doc/bison.texinfo: Promote `%long-directive' over
 857         `%long_directive'.
 858         Remove all references to fixed-output-files, yacc is enough.
 859
 860 2001-12-29  Akim Demaille  <akim@epita.fr>
 861
 862         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 863         user prologue.  These are defaults.
 864         * tests/actions.at (Mid-rule actions): Make sure the user can
 865         define YYDEBUG and YYERROR_VERBOSE.
 866
 867 2001-12-29  Akim Demaille  <akim@epita.fr>
 868
 869         * src/output.c (header_output): Don't forget to export YYLTYPE and
 870         yylloc.
 871         * tests/headers.at (export YYLTYPE): New, make sure it does.
 872         * tests/regression.at (%union and --defines, Invalid CPP headers):
 873         Move to...
 874         * tests/headers.at: here.
 875
 876 2001-12-29  Akim Demaille  <akim@epita.fr>
 877
 878         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 879
 880 2001-12-29  Akim Demaille  <akim@epita.fr>
 881
 882         * tests/actions.at (Mid-rule actions): Output on a single line
 883         instead of several.
 884
 885 2001-12-29  Akim Demaille  <akim@epita.fr>
 886
 887         * doc/bison.texinfo: Formatting changes.
 888
 889 2001-12-29  Akim Demaille  <akim@epita.fr>
 890
 891         Don't store the token defs in a muscle, just be ready to output it
 892         on command.  Now possible via `symbols'.  Fixes a memory leak.
 893
 894         * src/output.c (token_definitions_output): New.
 895         (output_parser, header_output): Use it.
 896         * src/reader.c (symbols_save): Remove.
 897
 898 2001-12-29  Akim Demaille  <akim@epita.fr>
 899
 900         * src/bison.simple: Do not provide a default for YYSTYPE and
 901         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 902         default.
 903
 904 2001-12-29  Akim Demaille  <akim@epita.fr>
 905
 906         Mid-rule actions are simply... ignored!
 907
 908         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 909         the empty-rule associated to the dummy symbol, not to the host
 910         rule.
 911         * tests/actions.at (Mid-rule actions): New.
 912
 913 2001-12-29  Akim Demaille  <akim@epita.fr>
 914
 915         Memory leak.
 916
 917         * src/reader.c (reader): Free grammar.
 918
 919 2001-12-29  Akim Demaille  <akim@epita.fr>
 920
 921         Memory leak.
 922
 923         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 924         since it allocates it for each state, although only one is needed.
 925         (allocate_storage): Do it here.
 926
 927 2001-12-29  Akim Demaille  <akim@epita.fr>
 928
 929         * src/options.h, src/options.c (create_long_option_table): Rename
 930         as...
 931         (long_option_table_new): this, with a clearer prototype.
 932         (percent_table): Remove, unused,
 933         * src/getargs.c (getargs): Adjust.
 934
 935 2001-12-29  Akim Demaille  <akim@epita.fr>
 936
 937         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 938         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 939         as states.
 940
 941 2001-12-29  Akim Demaille  <akim@epita.fr>
 942
 943         * src/lalr.c (build_relations): Rename `states' as `states1'.
 944         Sorry, I don't understand exactly what it is, no better name...
 945
 946 2001-12-29  Akim Demaille  <akim@epita.fr>
 947
 948         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 949         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 950         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 951         as rules.
 952
 953 2001-12-29  Akim Demaille  <akim@epita.fr>
 954
 955         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 956         ago.
 957
 958 2001-12-29  Akim Demaille  <akim@epita.fr>
 959
 960         * src/reader.c, src/reader.h (user_toknums): Remove.
 961         Adjust all users to use symbols[i]->user_token_number.
 962
 963 2001-12-29  Akim Demaille  <akim@epita.fr>
 964
 965         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 966         Adjust all users to use symbols[i]->prec or ->assoc.
 967
 968 2001-12-29  Akim Demaille  <akim@epita.fr>
 969
 970         * src/reader.c, src/reader.h (tags): Remove.
 971         Adjust all users to use symbols[i]->tag.
 972
 973 2001-12-29  Akim Demaille  <akim@epita.fr>
 974
 975         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 976         and rule_table.
 977         * src/reader.c (packsymbols): Fill this table.
 978         Drop sprec.
 979         * src/conflicts.c (resolve_sr_conflict): Adjust.
 980         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 981         single table.
 982         Use symbols[i]->tag instead of tags[i].
 983
 984 2001-12-29  Akim Demaille  <akim@epita.fr>
 985
 986         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 987         In addition, put a comment in there, to replace...
 988         * tests/regression.at (%union and C comments): Remove.
 989
 990 2001-12-29  Akim Demaille  <akim@epita.fr>
 991
 992         * tests/regression.at (Web2c Actions): Blindly move the actual
 993         output as expected output.  The contents *seem* right to me, but I
 994         can't pretend reading perfectly parser tables...  Nonetheless, all
 995         the other tests pass correctly, the table look OK, even though the
 996         presence of `$axiom' is to be noted: AFAICS it is useless (but
 997         harmless).
 998
 999 2001-12-29  Akim Demaille  <akim@epita.fr>
1000
1001         * src/reader.c (readgram): Don't add the rule 0 if there were no
1002         rules read.  In other words, add it _after_ having performed
1003         grammar sanity checks.
1004         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
1005
1006 2001-12-29  Akim Demaille  <akim@epita.fr>
1007
1008         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
1009         visible, and some states have now a different number.
1010
1011 2001-12-29  Akim Demaille  <akim@epita.fr>
1012
1013         * src/reader.c (readgram): Bind the initial rule's lineno to that
1014         of the first rule.
1015         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
1016         (Solved SR Conflicts): Adjust rule 0's line number.
1017
1018 2001-12-29  Akim Demaille  <akim@epita.fr>
1019
1020         Fix the `GAWK Grammar' failure.
1021
1022         * src/LR0.c (final_state): Initialize to -1 so that we do compute
1023         the reductions of the first state which was mistakenly confused
1024         with the final state because precisely final_state was initialized
1025         to 0.
1026         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
1027         now noticed by Bison.
1028         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
1029         have a reduction on $default.
1030
1031 2001-12-29  Akim Demaille  <akim@epita.fr>
1032
1033         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
1034         rule line numbers.
1035         * src/closure.c (print_closure): Likewise.
1036         * src/derives.c (print_derives): Likewise.
1037         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
1038         now.
1039
1040 2001-12-29  Akim Demaille  <akim@epita.fr>
1041
1042         * src/lalr.c (lookaheads_print): New.
1043         (lalr): Call it when --trace-flag.
1044         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
1045         are dumped.
1046
1047 2001-12-29  Akim Demaille  <akim@epita.fr>
1048
1049         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
1050         when walking through ritem, even via rule->rhs.
1051         * src/reduce.c (dump_grammar, useful_production, reduce_output)
1052         (useful_production, useless_nonterminals): Likewise.
1053         (reduce_grammar_tables): Likewise, plus update nritems.
1054         * src/nullable.c (set_nullable): Likewise.
1055         * src/lalr.c (build_relations): Likewise.
1056         * tests/sets.at (Nullable): Adjust.
1057         Fortunately, now, the $axiom is no longer nullable.
1058
1059 2001-12-29  Akim Demaille  <akim@epita.fr>
1060
1061         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
1062         the 0-sentinel.
1063         * src/gram.c (ritem_longest_rhs): Likewise.
1064         * src/reduce.c (nonterminals_reduce): Likewise.
1065         * src/print_graph.c (print_graph): Likewise.
1066         * src/output.c (output_rule_data): Likewise.
1067         * src/nullable.c (set_nullable):  Likewise.
1068
1069 2001-12-29  Akim Demaille  <akim@epita.fr>
1070
1071         * src/output.c: Comment changes.
1072
1073 2001-12-27  Paul Eggert  <eggert@twinsun.com>
1074
1075         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
1076         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
1077         Sparc, as they were causing more porting problems than the
1078         (minor) performance improvement was worth.
1079
1080         Also, catch up with 1.31's YYSTD.
1081
1082 2001-12-27  Akim Demaille  <akim@epita.fr>
1083
1084         * src/output.c (output_gram): Rely on nritems, not the
1085         0-sentinel.  See below.
1086         Use -1 as separator, not 0.
1087         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
1088         Rely on -1 as separator in yyrhs, instead of 0.
1089         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
1090         twice `Now at end of input', therefore there are two lines less to
1091         expect.
1092
1093 2001-12-27  Akim Demaille  <akim@epita.fr>
1094
1095         * tests/regression.at (Unresolved SR Conflicts):
1096         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
1097         below.
1098
1099 2001-12-27  Akim Demaille  <akim@epita.fr>
1100
1101         * src/LR0.c (new_state): Recognize the final state by the fact it
1102         is reached by eoftoken.
1103         (insert_start_shifting_state, insert_eof_shifting_state)
1104         (insert_accepting_state, augment_automaton): Remove, since now
1105         these states are automatically computed from the initial state.
1106         (generate_states): Adjust.
1107         * src/print.c: When reporting a rule number to the user, substract
1108         1, so that the axiom rule is rule 0, and the first user rule is 1.
1109         * src/reduce.c: Likewise.
1110         * src/print_graph.c (print_core): For the time being, just as for
1111         the report, depend upon --trace-flags to dump the full set of
1112         items.
1113         * src/reader.c (readgram): Once the grammar read, insert the rule
1114         0: `$axiom: START-SYMBOL $'.
1115         * tests/set.at: Adjust: rule 0 is now displayed, and since the
1116         number of the states has changed (the final state is no longer
1117         necessarily the last), catch up.

1120
1121         Try to make the use of the eoftoken valid.  Given that its value
1122         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
1123         is used instead of > 0 where appropriate, (ii), depend upon nritems
1124         instead of the 0-sentinel.
1125
1126         * src/gram.h, src/gram.c (nritems): New.
1127         Expected to be duplication of nitems, but for the time being...
1128         * src/reader.c (packgram): Assert nritems and nitems are equal.
1129         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
1130         * src/closure.c (print_closure, print_fderives): Likewise.
1131         * src/gram.c (ritem_print): Likewise.
1132         * src/print.c (print_core, print_grammar): Likewise.

1135 2001-12-27  Akim Demaille  <akim@epita.fr>
1136
1137         * src/main.c (main): If there are complains after grammar
1138         reductions, then output the report anyway if requested, then die.
1139         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
1140         * src/reader.c (eoftoken): New.
1141         (parse_token_decl): If the token being defined has value `0', it
1142         is the eoftoken.
1143         (packsymbols): No longer hack `tags' to insert `$' by hand.
1144         Be sure to preserve the value of the eoftoken.
1145         (reader): Make sure eoftoken is defined.
1146         Initialize nsyms to 0: now eoftoken is created just like the others.
1147         * src/print.c (print_grammar): Don't special case the eof token.
1148         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
1149         lie anyway, albeit pleasant.
1150         * tests/calc.at: Exercise error messages with eoftoken.
1151         Change the grammar so that empty input is invalid.
1152         Adjust expectations.
1153         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
1154
1155 2001-12-27  Akim Demaille  <akim@epita.fr>
1156
1157         * configure.in: Check the protos of strchr ans strspn.
1158         Replace strchr if needed.
1159         * src/system.h: Provide the protos of strchr, strspn and memchr if
1160         missing.
1161         * lib/strchr.c: New.
1162         * src/reader.c (symbols_save): Use strchr.
1163
1164 2001-12-27  Akim Demaille  <akim@epita.fr>
1165
1166         * src/print.c, src/print_graph.c (escape): New.
1167         Use it to quote the TAGS outputs.
1168         * src/print_graph.c (print_state): Now errors are in red, and
1169         reductions in green.
1170         Prefer high to wide: output the state number on a line of its own.
1171
1172 2001-12-27  Akim Demaille  <akim@epita.fr>
1173
1174         * src/state.h, src/state.c (reductions_new): New.

1196
1197         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
1198         * src/print.c: here.
1199         (lookaheadset, shiftset): New, used as additional storage by
1200         print_reductions.
1201         (print_results): Adjust.
1202         (print_shifts, print_gotos, print_errs): New, extracted from...
1203         (print_actions): here.
1204         * src/print_graph.c (print_actions): Remove dead code.
1205
1206 2001-12-27  Akim Demaille  <akim@epita.fr>
1207
1208         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
1209         `$n' and `@n'.
1210
1211 2001-12-27  Akim Demaille  <akim@epita.fr>
1212
1213         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
1214         (build_relations): Adjust.
1215
1216 2001-12-27  Akim Demaille  <akim@epita.fr>
1217
1218         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
1219         duplication.
1220
1221 2001-12-27  Akim Demaille  <akim@epita.fr>
1222
1223         * src/reader.c (packgram): Catch nitems overflows.
1224
1225 2001-12-27  Akim Demaille  <akim@epita.fr>
1226
1227         * src/files.c, src/files.h (guard_obstack): Remove.
1228         * src/output.c (output): Adjust.
1229         * src/reader.c (parse_braces): New, factoring...
1230         (copy_action, copy_guard): these two which are renamed as...
1231         (parse_action, parse_guard): these.
1232         As a voluntary consequence, using braces around guards is now
1233         mandatory.
1234
1235 2001-12-27  Akim Demaille  <akim@epita.fr>
1236
1237         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
1238         * src/reader.c (symbol_list): `guard' and `guard_line' are new
1239         members.
1240         (symbol_list_new): Adjust.
1241         (copy_action): action_line is the first line, not the last.
1242         (copy_guard): Just as for actions, store the `action' only, not
1243         the switch/case/break flesh.
1244         Don't parse the user action that might follow the guard, let...
1245         (readgram): do it, i.e., now, there can be an action after a
1246         guard.
1247         In other words the guard is just explicitly optional.
1248         (packgram): Adjust.
1249         * src/output.c (guards_output): New.
1250         (output_parser): Call it when needed.
1251         (output): Also free the guard and attrs obstacks.
1252         * src/files.c, src/files.h (obstack_save): Remove.
1253         (output_files): Remove.
1254         As a result, if one needs the former `.act' file, using an
1255         appropriate skeleton which requires actions and guards is now
1256         required.
1257         * src/main.c (main): Adjust.
1258         * tests/semantic.at: New.
1259         * tests/regression.at: Use `input.y' as input file name.
1260         Avoid 8+3 problems by requiring input.c when the test needs the
1261         parser.
1262
1263 2001-12-27  Akim Demaille  <akim@epita.fr>
1264

1268 2001-12-27  Akim Demaille  <akim@epita.fr>
1269
1270         All the hacks using a final pseudo state are now useless.
1271
1272         * src/LR0.c (set_state_table): state_table holds exactly nstates.
1273         * src/lalr.c (nLA): New.
1274         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
1275         instead of lookaheadsp from the pseudo state (nstate + 1).
1276
1277 2001-12-27  Akim Demaille  <akim@epita.fr>
1278
1279         * src/output.c (action_row, token_actions): Use a state_t instead
1280         of a integer, and nlookaheads instead of the following state's
1281         lookaheadsp.
1282
1283 2001-12-27  Akim Demaille  <akim@epita.fr>

1287         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
1288         (conflicts_print, print_reductions): Use a state_t instead of an
1289         integer when referring to a state.
1290         As much as possible, depend upon nlookaheads, instead of the
1291         `lookaheadsp' member of the following state (since lookaheads of
1292         successive states are successive, the difference between state n + 1
1293         and n served as the number of lookaheads for state n).
1294         * src/lalr.c (add_lookback_edge): Likewise.
1295         * src/print.c (print_core, print_actions, print_state)
1296         (print_results): Likewise.

1304         ANSIfy.
1305         Remove `register' indications.
1306         Add plenty of `static'.

1308 2001-12-27  Akim Demaille  <akim@epita.fr>
1309
1310         * src/output.c (prepare): Drop the muscle `ntbase' which
1311         duplicates ntokens.
1312         * src/bison.simple: Formatting/comment changes.
1313         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
1314         is an undocumented synonym.
1315
1316 2001-12-22  Akim Demaille  <akim@epita.fr>
1317
1318         * src/output.c (output_table_data): Change the prototype to use
1319         `int' for array ranges: some invocations do pass an int, not a
1320         short.
1321         Reported by Wayne Green.

1345         Reported by Nelson Beebee.
1346
1347         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with

1351
1352         * src/bison.simple: Don't hard code the skeleton line and filename.
1353         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1354         New line counter 'skeleton_line' (skeleton-line muscle).
1355
1356 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1357
1358         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1359         YYDEBUG must be defined to a nonzero value.
1360
1361         * src/bison.simple (yytname): Do not assume that the user defines

1400         * src/output.c (action_row, save_column, default_goto)

1417

1420
1421 2001-12-16  Marc Autret  <autret_m@epita.fr>
1422
1423         * src/bison.simple: Remove a useless #line directive.
1424         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1425         * src/output.c (get_lines_number): New.
1426         (output_parser): Adjust, now takes care about the lines of a
1427         output muscles.
1428         Fix line numbering.

1441 2001-12-15  Akim Demaille  <akim@epita.fr>
1442
1443         Make `make distcheck' work.
1444
1445         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1446         system.h which uses libgettext.h.
1447
1448 2001-12-15  Akim Demaille  <akim@epita.fr>
1449
1450         * src/nullable.c (set_nullable): Useless rules must be skipped,
1451         otherwise, since we range over their symbols, we might look at a
1452         nonterminal which no longer ``exists'', i.e., it is not counted in
1453         `nvars', hence we overflow our arrays.

1457         The header can also be produced directly, without any obstack!
1458         Yahoo!
1459
1460         * src/files.c, src/files.h (defines_obstack): Remove.
1461         (compute_header_macro): Global.
1462         (defines_obstack_save): Remove.
1463         * src/reader.c (parse_union_decl): No longer output to
1464         defines_obstack: its content can be found in the `stype' muscle
1465         anyway.
1466         (output_token_translations): Merge into...
1467         (symbols_output): this.
1468         Rename as...
1469         (symbols_save): this.
1470         (reader): Adjust.
1471         * src/output.c (header_output): New.
1472         (output): Call it.
1473
1474 2001-12-15  Akim Demaille  <akim@epita.fr>
1475
1476         * src/reader.c (parse_union_decl): Instead of handling two obstack
1477         simultaneously, use one to define the `stype' muscle, and use the
1478         value of the latter to fill defines_obstack.
1479         (copy_comment): Remove.
1480         (copy_comment2): Work for a single obstack.
1481         Rename as...

1485
1486         * src/lex.c, src/lex.h (xgetc): No longer static.
1487         * src/reader.c (parse_union_decl): Revamp.
1488
1489 2001-12-15  Akim Demaille  <akim@epita.fr>
1490
1491         Still making progress in separating Bison into (i) input, (ii)
1492         process, (iii) output: now we can directly output the parser file
1493         without using table_obstack at all.
1494
1495         * src/files.c, src/files.h (table_obstack): Bye bye.
1496         (parser_file_name): New.
1497         * src/files.c (compute_output_file_names): Compute it.
1498         * src/output.c (actions_output, output_parser)
1499         (output_master_parser): To a file instead of an obstack.
1500
1501 2001-12-15  Akim Demaille  <akim@epita.fr>
1502
1503         Attach actions to rules, instead of pre-outputting them to
1504         actions_obstack.
1505
1506         * src/gram.h (rule_t): action and action_line are new members.
1507         * src/reader.c (symbol_list): Likewise.
1508         (copy_action): Save the actions within the rule.
1509         (packgram): Save them in rule_table.
1510         * src/output.c (actions_output): New.
1511         (output_parser): Use it on `%%actions'.
1512         (output_rule_data): Don't free rule_table.
1513         (output): Do it.
1514         (prepare): Don't save the `action' muscle.
1515         * src/bison.simple: s/%%action/%%actions/.
1516
1517 2001-12-15  Akim Demaille  <akim@epita.fr>
1518
1519         * src/reader.c (copy_action): When --yacc, don't append a `;'
1520         to the user action: let it fail if lacking.
1521         Suggested by Arnold Robbins and Tom Tromey.
1522
1523 2001-12-14  Akim Demaille  <akim@epita.fr>
1524
1525         * src/lex.c (literalchar): Simply return the char you decoded, non
1526         longer mess around with obstacks and int pointers.
1527         Adjust all callers.
1528
1529 2001-12-14  Akim Demaille  <akim@epita.fr>
1530
1531         * src/lex.c (literalchar): Don't escape the special characters,
1532         just decode them, and keep them as char (before, eol was output as
1533         the 2 char string `\n' etc.).
1534         * src/output.c (output_rule_data): Use quotearg to output the
1535         token strings.
1536
1537 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1538
1539         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1540         Do not infringe on the global user namespace when using C++.
1541         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1542         All uses of `fprintf' and `stderr' changed.
1543
1544         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1545
1546 2001-12-13  Akim Demaille  <akim@epita.fr>
1547
1548         The computation of nullable is broken: it doesn't handle empty
1549         RHS's properly.
1550
1551         * tests/torture.at (GNU AWK Grammar): New.
1552         * tests/sets.at (Nullable): New.
1553         * src/nullable.c (set_nullable): Instead of blindly looping over
1554         `ritems', loop over the rules, and then over their rhs's.
1555
1556         Work around Autotest bugs.
1557
1558         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1559         frame, because Autotest understand lines starting with a `+' as
1560         traces from the shell.  Then, they are not processed properly.
1561         Admittedly an Autotest bug, but we don't have time to wait for
1562         Autotest to catch up.
1563         * tests/regression.at (Broken Closure): Adjust to the new table
1564         frames.
1565         Move to...
1566         * tests/sets.at: here.
1567
1568 2001-12-13  Akim Demaille  <akim@epita.fr>
1569
1570         * src/closure.c (closure): Use nrules instead of playing tricks
1571         with BITS_PER_WORD.
1572
1573 2001-12-13  Akim Demaille  <akim@epita.fr>
1574
1575         * src/print.c (print_actions): Output the handling of `$' as the
1576         traces do: shifting the token EOF.  Before EOF was treated as a
1577         nonterminal.
1578         * tests/regression.at: Adjust some tests.
1579         * src/print_graph.c (print_core): Complete the set of items via
1580         closure.  The next-to-final and final states are still unsatisfying,
1581         but that's to be addressed elsewhere.
1582         No longer output the rule numbers, but do output the state number.
1583         A single loop for the shifts + gotos is enough, but picked a
1584         distinct color for each.
1585         (print_graph): Initialize and finalize closure.
1586
1587 2001-12-13  Akim Demaille  <akim@epita.fr>
1588
1589         * src/reader.c (readgram): Remove dead code, an strip useless
1590         braces.
1591         (get_type): Remove, unused.
1592
1593 2001-12-12  Akim Demaille  <akim@epita.fr>
1594
1595         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1596         on that of lib/error.c.
1597
1598 2001-12-12  Akim Demaille  <akim@epita.fr>
1599
1600         Some hosts don't like `/' in includes.
1601
1602         * src/system.h: Include libgettext.h without qualifying the path.
1603         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1604         $(top_srcdir).
1605
1606 2001-12-11  Marc Autret  <autret_m@epita.fr>
1607
1608         * src/output.c (output_parser): Remove useless muscle.
1609
1610 2001-12-11  Marc Autret  <autret_m@epita.fr>
1611
1612         * src/bison.simple: Remove #line just before %%epilogue. It
1613         is now handled in ...
1614         * src/reader.c (read_additionnal_code): Add the output of a
1615         #line for the epilogue.
1616
1617 2001-12-10  Marc Autret  <autret_m@epita.fr>
1618
1619         * src/reader.c (copy_definition): Re-use CPP-outed code which
1620         replace precedent remove.
1621         * src/bison.simple: Remove #line before %%prologue because
1622         %%input-line is wrong at this time.
1623
1624 2001-12-10  Marc Autret  <autret_m@epita.fr>
1625
1626         * src/reader.c (symbols_output): Clean up.
1627         * src/output.c (output_gram, output): Clean up.
1628
1629 2001-12-10  Akim Demaille  <akim@epita.fr>
1630
1631         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1632         * src/LR0.c (set_state_table): here.
1633         * src/lalr.c (lalr): Call it.
1634
1635 2001-12-10  Akim Demaille  <akim@epita.fr>
1636
1637         * src/state.h (shifts): Remove the `number' member: shifts are
1638         attached to state, hence no longer need to be labelled with a
1639         state number.
1640
1641 2001-12-10  Akim Demaille  <akim@epita.fr>
1642
1643         Now that states have a complete set of members, the linked list of
1644         shifts is useless: just fill directly the state's shifts member.
1645
1646         * src/state.h (shifts): Remove the `next' member.
1647         * src/LR0.c (first_state, last_state): Remove.
1648         Adjust the callers.
1649         (augment_automaton): Don't look for the shifts that must be added
1650         a shift on EOF: it is those of the state we looked for!  But now,
1651         since shifts are attached, it is no longer needed to looking
1652         merely by its id: its number.
1653
1654 2001-12-10  Akim Demaille  <akim@epita.fr>
1655
1656         * src/LR0.c (augment_automaton): Better variable locality.
1657         Remove an impossible branch: if there is a state corresponding to
1658         the start symbol being shifted, then there is shift for the start
1659         symbol from the initial state.
1660
1661 2001-12-10  Akim Demaille  <akim@epita.fr>
1662
1663         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1664         only when appropriate: when insert_start_shifting_state' is not
1665         invoked.
1666         * tests/regression.at (Rule Line Numbers): Adjust.
1667
1668 2001-12-10  Akim Demaille  <akim@epita.fr>
1669
1670         * src/LR0.c (augment_automaton): Now that all states have shifts,
1671         merge the two cases addition shifts to the initial state.
1672
1673 2001-12-10  Akim Demaille  <akim@epita.fr>
1674
1675         * src/lalr.c (set_state_table): Move to...
1676         * src/LR0.c: here.
1677         * src/lalr.c (lalr): Don't call it...
1678         * src/LR0.c (generate_states): do it.
1679         * src/LR0.h (first_state): Remove, only the table is used.
1680
1681 2001-12-10  Akim Demaille  <akim@epita.fr>
1682
1683         * src/LR0.h (first_shift, first_reduction): Remove.
1684         * src/lalr.c: Don't use first_shift: find shifts through the
1685         states.
1686
1687 2001-12-10  Akim Demaille  <akim@epita.fr>
1688
1689         * src/LR0.c: Attach shifts to states as soon as they are
1690         computed.
1691         * src/lalr.c (set_state_table): Instead of assigning shifts to
1692         state, just assert that the mapping was properly done.
1693
1694 2001-12-10  Akim Demaille  <akim@epita.fr>
1695
1696         * src/LR0.c (insert_start_shift): Rename as...
1697         (insert_start_shifting_state): this.
1698         (insert_eof_shifting_state, insert_accepting_state): New.
1699         (augment_automaton): Adjust.
1700         Better locality of the variables.
1701         When looking if the start_symbol is shifted from the initial
1702         state, using `while (... symbol != start_symbol ...)' sounds
1703         better than `while (... symbol < start_symbol ...)': If fail
1704         to see how the order between symbols could be relevant!
1705
1706 2001-12-10  Akim Demaille  <akim@epita.fr>
1707
1708         * src/getargs.h: Don't declare `spec_name_prefix' and
1709         `spec_file_prefix', declared by src/files.h.
1710         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1711         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1712         * src/output.c (prepare): Adjust.
1713         * src/reader.c (symbols_output): Likewise.
1714         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1715
1716 2001-12-10  Akim Demaille  <akim@epita.fr>
1717
1718         * src/muscle_tab.c (muscle_init): NULL is a better default than
1719         `"0"'.
1720
1721 2001-12-10  Akim Demaille  <akim@epita.fr>
1722
1723         * src/reader.c (reader): Calling symbols_output once is enough.
1724
1725 2001-12-10  Akim Demaille  <akim@epita.fr>
1726
1727         Now that states have a complete set of members, the linked list of
1728         reductions is useless: just fill directly the state's reductions
1729         member.
1730
1731         * src/state.h (struct reductions): Remove member `number' and
1732         `next'.
1733         * src/LR0.c (first_reduction, last_reduction): Remove.
1734         (save_reductions): Don't link the new reductions, store them in
1735         this_state.
1736         * src/lalr.c (set_state_table): No need to attach reductions to
1737         states, it's already done.
1738         * src/output.c (output_actions): No longer free the shifts, then
1739         the reductions, then the states: free all the states and their
1740         members.
1741
1742 2001-12-10  Akim Demaille  <akim@epita.fr>
1743
1744         * src/options.c (OPTN, DRTV, BOTH): New.
1745         (option_table): Use them.
1746
1747         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1748         the job of system.h.
1749         * src/options.c: Don't include stdio.h and xalloc.h for the same
1750         reasons.
1751
1752 2001-12-10  Akim Demaille  <akim@epita.fr>
1753
1754         * src/output.c (output, prepare): Make sure the values of the
1755         muscles `action' and `prologue' are 0-terminated.
1756
1757 2001-12-10  Akim Demaille  <akim@epita.fr>
1758
1759         Clean up GCC warnings.
1760
1761         * src/reader.c (copy_action): `buf' is not used.
1762         (parse_skel_decl): Be static.
1763         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1764         * src/options.h (create_long_option_table): Have a real prototype.
1765         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1766         (hash_delete_at): Return const void *.
1767         Adjust casts to preserve the const.
1768
1769 2001-12-10  Akim Demaille  <akim@epita.fr>
1770
1771         * configure.in: Require 2.52g.
1772         M4 is not needed, but AUTOM4TE is.
1773         * m4/m4.m4: Remove.
1774         * tests/Makefile.am: Adjust.
1775
1776 2001-12-10  Akim Demaille  <akim@epita.fr>
1777
1778         One structure for states is enough, even though theoretically
1779         there are LR(0) states and LALR(1) states.
1780
1781         * src/lalr.h (state_t): Remove.
1782         (state_table): Be state_t **, not state_t *.
1783         * src/state.h (core, CORE_ALLOC): Rename as...
1784         (state_t, STATE_ALLOC): this.
1785         Add the LALR(1) members: shifts, reductions, errs.
1786         * src/LR0.c (state_table): Rename as...
1787         (state_hash): this, to avoid name clashes with the global
1788         `state_table'.
1789         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1790         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

1796
1797         * src/warshall.c (bitmatrix_print): New.
1798         (TC): Use it.
1799         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1800         j must be the outer loop.

1811         * src/conflicts.c (err_table): Remove.
1812         (resolve_sr_conflict): Adjust.
1813         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1814         Rename as...
1815         (state_t.reductions, state_t.shifts): this.
1816
1817 2001-12-05  Akim Demaille  <akim@epita.fr>
1818
1819         * src/reduce.c (reduce_grammar_tables): No longer disable the
1820         removal of useless rules via CPP but via `if (0)', so that the
1821         compiler still check the code is valid.
1822         For instance, it should have noticed `rline' no longer exists: use
1823         the `line' member of rule_t.
1824         * src/gram.c (dummy, rline): Remove, unused.
1825
1826 2001-12-05  Akim Demaille  <akim@epita.fr>
1827
1828         * src/output.c (pack_vector): Use assert, not berror.
1829         * src/main.c (berror): Remove, unused.
1830
1831 2001-12-05  Akim Demaille  <akim@epita.fr>
1832
1833         New experimental feature: if --verbose --trace output all the
1834         items of a state, not only its kernel.
1835
1836         * src/print.c (print_core): If `trace_flag', then invoke closure
1837         before outputting the items of the state (print_core is no longer
1838         a correct name them).
1839         (print_results): Invoke new_closure/free_closure if needed.
1840
1841 2001-12-05  Akim Demaille  <akim@epita.fr>
1842
1843         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1844         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1845         (nitemset): for consistency with the rest of the project.
1846
1847 2001-12-05  Akim Demaille  <akim@epita.fr>
1848
1849         * src/closure.c (print_closure): Improve.
1850         (closure): Use it for printing input and output.
1851
1852 2001-12-05  Akim Demaille  <akim@epita.fr>
1853
1854         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1855         indexed by nonterminals.
1856
1857 2001-12-05  Akim Demaille  <akim@epita.fr>
1858
1859         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1860         what it was!).
1861         * src/warshall.h: Remove accidental duplication of the content.
1862
1863 2001-12-05  Akim Demaille  <akim@epita.fr>
1864
1865         * src/closure.c (set_fderives): De-obfuscate.
1866
1867 2001-12-05  Akim Demaille  <akim@epita.fr>
1868
1869         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1870
1871 2001-12-05  Akim Demaille  <akim@epita.fr>
1872
1873         * src/closure.c (set_firsts): De-obfuscate.
1874
1875 2001-12-05  Akim Demaille  <akim@epita.fr>
1876
1877         * src/output.c (action_row): De-obfuscate
1878         using the good o' techniques: arrays not pointers, variable
1879         locality, BITISSET, RESETBIT etc.
1880
1881 2001-12-05  Akim Demaille  <akim@epita.fr>
1882
1883         Pessimize the code to simplify it: from now on, all the states
1884         have a valid SHIFTS, which NSHIFTS is possibly 0.
1885
1886         * src/LR0.c (shifts_new): Be global and move to..
1887         * src/state.c, src/state.h: here.
1888         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1889         * src/print_graph: Adjust.
1890
1891 2001-12-05  Akim Demaille  <akim@epita.fr>
1892
1893         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1894         * src/conflicts.c: Use it.
1895         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1896         incorrectly ``simplified''.
1897
1898 2001-12-05  Akim Demaille  <akim@epita.fr>
1899
1900         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1901         using the good o' techniques: arrays not pointers, variable
1902         locality, BITISSET, RESETBIT etc.
1903
1904 2001-12-05  Akim Demaille  <akim@epita.fr>
1905
1906         * src/state.h (SHIFT_SYMBOL): New.
1907         * src/conflicts.c: Use it to deobfuscate.
1908
1909 2001-12-05  Akim Demaille  <akim@epita.fr>
1910
1911         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1912         (print_reductions): De-obfuscate using the good o' techniques:
1913         arrays not pointers, variable locality, BITISSET.
1914
1915 2001-12-05  Akim Demaille  <akim@epita.fr>
1916
1917         * src/conflicts.c (print_reductions): Arrays, not pointers.
1918         Use BITISSET.
1919
1920 2001-12-05  Akim Demaille  <akim@epita.fr>
1921
1922         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1923
1924 2001-12-05  Akim Demaille  <akim@epita.fr>
1925
1926         * src/conflicts.c (print_reductions): Improve variable locality.
1927
1928 2001-12-05  Akim Demaille  <akim@epita.fr>
1929
1930         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1931
1932 2001-12-05  Akim Demaille  <akim@epita.fr>
1933
1934         * src/conflicts.c (print_reductions): Improve variable locality.
1935
1936 2001-12-05  Akim Demaille  <akim@epita.fr>
1937
1938         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1939         * src/lalr.c: Use them.
1940
1941 2001-12-05  Akim Demaille  <akim@epita.fr>
1942
1943         * src/LR0.c (augment_automaton): Formatting changes.
1944         Better variable locality.
1945
1946 2001-12-05  Akim Demaille  <akim@epita.fr>
1947
1948         * src/lalr.c (matrix_print): New.
1949         (transpose): Use it.
1950         Use arrays instead of pointers.
1951
1952 2001-12-05  Akim Demaille  <akim@epita.fr>
1953
1954         * src/lalr.c (maxrhs): Move to...
1955         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1956         * src/lalr.c (build_relations): Adjust.
1957
1958 2001-12-05  Akim Demaille  <akim@epita.fr>
1959
1960         * src/lalr.c (transpose): Free the memory allocated to the
1961         argument, as it is replaced by the results by the unique caller.
1962         (build_relations): Merely invoke transpose: it handles the memory
1963         deallocation.
1964         Improve variable locality.
1965         Avoid variables used as mere abbreviations.
1966         (compute_lookaheads): Use arrays instead of pointers.
1967
1968 2001-12-05  Akim Demaille  <akim@epita.fr>
1969
1970         * src/lalr.c (initialize_F): Improve variable locality.
1971         Avoid variables used as mere abbreviations.
1972
1973 2001-12-05  Akim Demaille  <akim@epita.fr>
1974
1975         * src/derives.c (print_derives): Display the ruleno.
1976         * src/lalr.c (initialize_F, transpose): Better variable locality
1977         to improve readability.
1978         Avoid variables used as mere abbreviations.
1979
1980 2001-12-05  Akim Demaille  <akim@epita.fr>
1981
1982         * src/lalr.c (traverse): Use arrays instead of pointers.
1983
1984 2001-12-05  Akim Demaille  <akim@epita.fr>
1985
1986         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1987         the handling of squeue.
1988         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1989
1990 2001-12-05  Akim Demaille  <akim@epita.fr>
1991
1992         Because useless nonterminals are now kept alive (instead of being
1993         `destroyed'), we now sometimes examine them, and store information
1994         related to them.  Hence we need to know their number, and adjust
1995         memory allocations.
1996
1997         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1998         static.
1999         * src/LR0.c (allocate_itemsets): The memory allocated to
2000         `symbol_count' was used for two different purpose: once to count
2001         the number of occurrences of each symbol, and later reassigned to
2002         `shift_symbol', containing the symbol that can be shifted from a
2003         given state.
2004         Deobfuscate, i.e., allocate, use and free `symbol_count' here
2005         only, and...
2006         (new_itemsets): Allocate `shift_symbol' here.
2007         (allocate_itemsets): symbol_count includes useless nonterminals.
2008         Make room for them.
2009         (free_storage): Use `free', not `XFREE', for pointers that cannot
2010         be null.
2011
2012 2001-12-05  Akim Demaille  <akim@epita.fr>
2013
2014         * src/nullable.c (set_nullable): Deobfuscate the handling of
2015         ritem.
2016         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
2017
2018 2001-12-05  Akim Demaille  <akim@epita.fr>
2019
2020         * src/gram.c, src/gram.h (ritem_print): New.
2021         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
2022         (This useless function was defined only to work around VMS linkers
2023         that can't handle compilation units with variables only).
2024         * src/reduce.c (dump_grammar): Use it to trace the construction of
2025         ritem.
2026
2027 2001-12-04  Paul Eggert  <eggert@twinsun.com>
2028
2029         * src/bison.simple (union yyalloc): Change member names
2030         to be the same as the stack names.
2031         (yyparse): yyptr is now union yyalloc *, not char *.
2032         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
2033         and may generate better code on some machines.
2034         (yystpcpy): Use prototype if __STDC__ is defined, not just
2035         if __cplusplus is defined.
2036
2037 2001-11-30  Akim Demaille  <akim@epita.fr>
2038
2039         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
2040         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
2041         Gettext doesn't compile cleanly, and dies with -Werror.
2042         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
2043         Include WARNING_CFLAGS here.
2044         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
2045         before being defined.
2046
2047 2001-11-27  Paul Eggert  <eggert@twinsun.com>
2048
2049         * lib/quotearg.h (quotearg_n, quotearg_n_style):
2050         First arg is int, not unsigned.
2051         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
2052         (SIZE_MAX, UINT_MAX): New macros.
2053         (quotearg_n_options): Abort if N is negative.
2054         Avoid overflow check on hosts where size_t is 64 bits and int
2055         is 32 bits, as overflow is impossible there.
2056         Fix off-by-one typo that caused unnecessary reallocation.
2057
2058 2001-11-29  Paul Eggert  <eggert@twinsun.com>
2059
2060         Name space cleanup in generated parser.
2061
2062         * doc/bison.texinfo (Bison Parser): Discuss system headers
2063         and their effect on the user name space.
2064
2065         * src/bison.simple:
2066         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
2067         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
2068         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
2069
2070         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
2071         on user names when possible.
2072
2073         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
2074         Simplify test for whather <alloca.h> exists.
2075
2076         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
2077
2078         (<stdio.h>): Include if YYDEBUG.
2079
2080         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
2081         ! defined (yyoverflow) && ! defined (yymemcpy).
2082
2083         (yymemcpy, yyparse): Rename local variables as needed so that
2084         they all begin with 'yy'.
2085
2086         (yystrlen, yystpcpy): New functions.
2087
2088         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
2089         All uses changed.
2090
2091         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
2092         instead of relying on string.h functions.  Use YYSTACK_ALLOC
2093         and YYSTACK_FREE instead of malloc and free.
2094
2095 2001-11-30  Akim Demaille  <akim@epita.fr>
2096
2097         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
2098         before their first uses.
2099         (YYBISON, YYPURE): Move to the top of the output.
2100
2101 2001-11-30  Akim Demaille  <akim@epita.fr>
2102
2103         * tests/reduce.at (Useless Nonterminals): Fix.
2104
2105 2001-11-30  Akim Demaille  <akim@epita.fr>
2106
2107         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
2108         if body instead of `;' to pacify GCC's warnings.
2109
2110 2001-11-30  Akim Demaille  <akim@epita.fr>
2111
2112         Instead of mapping the LHS of unused rules to -1, keep the LHS
2113         valid, but flag the rules as invalid.
2114
2115         * src/gram.h (rule_t): `useful' is a new member.
2116         * src/print.c (print_grammar): Adjust.
2117         * src/derives.c (set_derives): Likewise.
2118         * src/reader.c (packgram, reduce_output): Likewise.
2119         * src/reduce.c (reduce_grammar_tables): Likewise.
2120         * tests/reduce.at (Underivable Rules, Useless Rules): New.
2121
2122 2001-11-30  Akim Demaille  <akim@epita.fr>
2123
2124         * src/reduce.c (reduce_output): Formatting changes.
2125         * src/print.c (print_results, print_grammar): Likewise.
2126         * tests/regression.at (Rule Line Numbers)
2127         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
2128
2129 2001-11-30  Akim Demaille  <akim@epita.fr>
2130
2131         * src/reduce.c (nonterminals_reduce): Instead of throwing away
2132         useless nonterminals, move them at the end of the symbol arrays.
2133         (reduce_output): Adjust.
2134         * tests/reduce.at (Useless Nonterminals): Adjust.
2135
2136 2001-11-30  Akim Demaille  <akim@epita.fr>
2137
2138         * src/reduce.c: Various comment/formatting changes.
2139         (nonterminals_reduce): New, extracted from...
2140         (reduce_grammar_tables): here.
2141         (reduce_grammar): Call nonterminals_reduce.
2142
2143 2001-11-29  Paul Eggert  <eggert@twinsun.com>
2144
2145         * src/bison.simple (YYSTACK_REALLOC): Remove.
2146         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
2147         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
2148         New macros.
2149         (union yyalloc): New type.
2150         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
2151         an arbitrary restriction on hosts where size_t is wider than int.
2152
2153         (yyparse): Don't dump core if alloca or malloc fails; instead, report
2154         a parser stack overflow.  Allocate just one block of memory for all
2155         three stacks, instead of allocating three blocks; this typically is
2156         faster and reduces fragmentation.
2157
2158         Do not limit the number of items in the stack to a value that fits
2159         in 'int', as this is an arbitrary limit on hosts with 64-bit
2160         size_t and 32-bit int.
2161
2162 2001-11-29  Marc Autret  <autret_m@epita.fr>
2163
2164         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
2165         of defining YYERROR_VERBOSE.
2166         [AT_DATA]: $4 is now out of C declarations in the prologue.
2167

3950         * m4/error.m4: Run AC_FUNC_STRERROR_R.

3952
3953 2001-03-16  Akim Demaille  <akim@epita.fr>
3954
3955         * src/getargs.c (longopts): Clean up.
3956
3957 2001-02-21  Akim Demaille  <akim@epita.fr>
3958
3959         * src/reader.c (gensym): `gensym_count' is your own.
3960         Use a static buf to create the symbol name, as token_buffer is no
3961         longer a buffer.
3962
3963 2001-02-08  Akim Demaille  <akim@epita.fr>
3964
3965         * src/conflicts.c (conflict_report): Be sure not to append to res
3966         between two calls, which could happen if both first sprintf were
3967         skipped, but not the first cp += strlen.
3968
3969 2001-02-08  Akim Demaille  <akim@epita.fr>
3970
3971         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
3972         New, from fileutils 4.0.37.
3973         * configure.in: Require Autoconf 2.49c.  I took some time before
3974         making this decision.  This is the only way out for portability
3975         issues in Bison, it would mean way too much duplicate effort to
3976         import in Bison features implemented in 2.49c since 2.13.
3977         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
3978
3979 2001-02-02  Akim Demaille  <akim@epita.fr>

3983
3984 2001-01-19  Akim Demaille  <akim@epita.fr>
3985
3986         Get rid of the ad hoc handling of token_buffer in the scanner: use
3987         the obstacks.
3988
3989         * src/lex.c (token_obstack): New.
3990         (init_lex): Initialize it.  No longer call...
3991         (grow_token_buffer): this.  Remove it.
3992         Adjust all the places which used it to use the obstack.
3993
3994 2001-01-19  Akim Demaille  <akim@epita.fr>
3995
3996         * src/lex.h: Rename all the tokens:
3997         s/\bENDFILE\b/tok_eof/g;
3998         s/\bIDENTIFIER\b/tok_identifier/g;
3999         etc.
4000         Let them be enums, not #define, to ease debugging.
4001         Adjust all the code.
4002
4003 2001-01-18  Akim Demaille  <akim@epita.fr>
4004
4005         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
4006         * src/lex.c (maxtoken, grow_token_buffer): Static.
4007
4008 2001-01-18  Akim Demaille  <akim@epita.fr>
4009
4010         Since we now use obstacks, more % directives can be enabled.
4011
4012         * src/lex.c (percent_table): Also accept `%yacc',
4013         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
4014         `%debug'.
4015         Handle the actions for `%semantic_parser' and `%pure_parser' here,
4016         instead of returning a token.
4017         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
4018         * src/reader.c (read_declarations): Adjust.
4019         * src/files.c (open_files): Don't call `compute_base_names', don't
4020         compute `attrsfile' since they depend upon data which might be
4021         *in* the input file now.
4022         (output_files): Do it here.
4023         * src/output.c (output_headers): Document the fact that this patch
4024         introduces a guaranteed SEGV for semantic parsers.
4025         * doc/bison.texinfo: Document them.
4026         * tests/suite.at: Exercise these %options.
4027
4028 2000-12-20  Akim Demaille  <akim@epita.fr>
4029
4030         Also handle the output file (--verbose) with obstacks.
4031
4032         * files.c (foutput): Remove.
4033         (output_obstack): New.
4034         Adjust all dependencies.
4035         * src/conflicts.c: Return a string.
4036         * src/system.h (obstack_grow_string): Rename as...
4037         (obstack_sgrow): this.  Be ready to work with non literals.
4038         (obstack_fgrow4): New.

4040 2000-12-20  Akim Demaille  <akim@epita.fr>
4041
4042         * src/files.c (open_files): Fix the computation of short_base_name
4043         in the case of `-o foo.tab.c'.
4044
4045 2000-12-20  Akim Demaille  <akim@epita.fr>
4046
4047         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
4048         (copy_dollar): Now that everything uses obstacks, get rid of the
4049         FILE * parameters.
4050
4051 2000-12-20  Akim Demaille  <akim@epita.fr>
4052
4053         * src/files.c (open_files): Actually the `.output' file is based
4054         on the short_base_name, not base_name.
4055         * tests/suite.at (Checking output file names): Adjust.
4056
4057 2000-12-20  Akim Demaille  <akim@epita.fr>
4058
4059         * src/bison.s1: Remove, we now use directly...
4060         * src/bison.simple: this.
4061         * src/Makefile.am: Use pkgdata instead of data.
4062
4063 2000-12-20  Akim Demaille  <akim@epita.fr>

4074         vars.
4075         (open_files): Don't compute them.
4076         (output_files): Adjust.
4077         (base_name, short_base_name): Be global.
4078         Adjust dependencies.
4079
4080 2000-12-19  Akim Demaille  <akim@epita.fr>
4081
4082         * src/files.c (strsuffix): New.
4083         (stringappend): Be just like strcat but allocate.
4084         (base_names): Eve out from open_files.
4085         Try to simplify the rather hairy computation of base_name and
4086         short_base_name.
4087         (open_files): Use it.
4088         * tests/suite.at (Checking output file names): New test.

4094         * src/output.c (output_parser): Recognize `%% actions' instead of
4095         `$'.
4096         * src/bison.s1: s/$/%% actions/.
4097         * src/bison.hairy: Likewise.
4098
4099 2000-12-19  Akim Demaille  <akim@epita.fr>
4100
4101         * src/output.c (output_parser): Compute the `#line' lines when
4102         there are.
4103         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
4104         Suggested by Hans Aberg.
4105
4106 2000-12-19  Akim Demaille  <akim@epita.fr>
4107
4108         Let the handling of the skeleton files be local to the procedures
4109         that use it.
4110
4111         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
4112         longer static.
4113         (fparser, open_extra_files): Remove.
4114         (open_files, output_files): Don't take care of fparser.

4121 2000-12-19  Akim Demaille  <akim@epita.fr>
4122

4125
4126 2000-12-19  Akim Demaille  <akim@epita.fr>
4127
4128         * src/files.c (open_files): Yipee!  We no longer need all the code
4129         looking for `/tmp' since we have no tmp file.
4130
4131 2000-12-19  Akim Demaille  <akim@epita.fr>
4132
4133         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

4135         * src/files.c (open_files): Less dependency on MSDOS etc.

4159
4160         * lib/obstack.h: Formatting changes.
4161         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
4162         prevents type checking.
4163         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
4164         cast the value to (void *): assigning a `foo *' to a `void *'
4165         variable is valid.
4166         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
4167         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

4183
4184         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

4202
4203 2000-11-07  Akim Demaille  <akim@epita.fr>
4204
4205         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
4206         Merge in a single CPP if/else.
4207
4208 2000-11-07  Akim Demaille  <akim@epita.fr>
4209
4210         * src/output.c (output): Remove useless variables.
4211         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
4212         argument `data' for consistency with the prototypes.
4213         Qualify it `const'.
4214         (obstack_copy, obstack_copy0): Rename the second argument as
4215         `address' for consistency.  Qualify it `const'.

4217         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
4218         `const' their input argument (`data' or `address').

4221 2000-11-03  Akim Demaille  <akim@epita.fr>

4225         Adjust dependencies.
4226
4227 2000-11-03  Akim Demaille  <akim@epita.fr>
4228
4229         For some reason, this was not applied.
4230
4231         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

4235

4246         Use `obstack_save'.
4247         * src/main.c (main): Don't use `atexit' to register `done', since
4248         it no longer has to remove tmp files, just call `output_files'
4249         when there are no errors.
4250
4251 2000-11-02  Akim Demaille  <akim@epita.fr>

4321         the `/' which is suspected to open a comment, instead of being
4322         called after `//' or `/*' was read.
4323         (copy_comment, copy_definition, parse_union_decl, copy_action)
4324         (copy_guard): Adjust.

4351
4352 2000-10-04  Akim Demaille  <akim@epita.fr>
4353
4354         When a literal string is used to define two different tokens,
4355         `bison -v' segfaults.
4356         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4357
4358         * tests/regression.m4: New file.
4359         Include the core of the sample provided by Piotr Gackiewicz.

4361         properly.

4364
4365         * src/reader.c (parse_expect_decl): Keep `count' within the size
4366         of `buffer'.
4367         From Neil Booth.
4368
4369 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4370
4371         * bison.s1 (yyparse): Assign the default value
4372         unconditionally, to avoid a GCC warning and make the parser a
4373         tad smaller.
4374
4375 2000-10-02  Akim Demaille  <akim@epita.fr>
4376
4377         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
4378         options.
4379
4380 2000-10-02  Akim Demaille  <akim@epita.fr>
4381
4382         * src/derives.c, src/print.c, src/reduce.c: To ease the
4383         translation, move some `\n' out of the translated strings.
4384
4385 2000-10-02  Akim Demaille  <akim@epita.fr>
4386
4387         The location tracking mechanism is precious for parse error
4388         messages.  Nevertheless, it is enabled only when `@n' is used in
4389         the grammar, which is a different issue (you can use it in error
4390         message, but not in the grammar per se).  Therefore, there should
4391         be another means to enable it.
4392
4393         * src/getargs.c (getargs): Support `--locations'.
4394         (usage): Report it.
4395         * src/getargs.h (locationsflag): Export it.
4396         * src/lex.c (percent_table): Support `%locations'.
4397         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4398         with `locationsflag'.
4399         * doc/bison.texinfo: Document `--locations' and `%locations'.
4400         Sort the options.
4401         * tests/calc.m4: Test it.
4402
4403         For regularity of the names, replace each
4404         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4405         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4406         In addition replace each `flag' with `_flag'.
4407
4408 2000-10-02  Akim Demaille  <akim@epita.fr>
4409
4410         Also test parse error messages, including with YYERROR_VERBOSE.
4411
4412         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4413         associative).
4414         Use it to check the computations.
4415         Use it to check `nonassoc' is honored.
4416         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4417         `--yyerror-verbose'.
4418         (_AT_CHECK_CALC): Adjust to this option.
4419         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4420
4421 2000-10-02  Akim Demaille  <akim@epita.fr>
4422
4423         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4424         the latter demonstrates a flaw in the handling of non debugging
4425         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4426         was used in order to simplify:
4427
4428         #if YYDEBUG
4429         if (yydebug)
4430         {
4431         ...
4432         }
4433         #endif
4434
4435         into
4436
4437         if (yydebug)
4438         {
4439         ...
4440         }
4441
4442         unfortunately this leads to a CPP conflict when
4443         `--name-prefix=foo' is used since it produces `#define yydebug
4444         foodebug'.
4445
4446         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4447         (YYDPRINTF): New macro.
4448         Spread its use.
4449         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4450         the bison options.
4451         Also test `--verbose', `--defines' and `--name-prefix'.
4452
4453 2000-10-02  Akim Demaille  <akim@epita.fr>
4454
4455         Improve the readability of the produced parsers.
4456
4457         * src/bison.s1: Formatting changes.
4458         Improve the comment related to the `$' mark.
4459         (yydefault): Don't fall through to `yyresume': `goto' there.
4460         * src/output.c (output_parser): When the `$' is met, skip the end
4461         of its line.
4462         New variable, `number_of_dollar_signs', to check there's exactly
4463         one `$' in the parser skeleton.
4464
4465 2000-10-02  Akim Demaille  <akim@epita.fr>
4466
4467         * lib/xstrdup.c: New file, from the fileutils.
4468         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4469         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4470         instead of strlen + xmalloc + strcpy.
4471         * src/symtab.c (copys): Remove, use xstrdup instead.
4472
4473 2000-10-02  Akim Demaille  <akim@epita.fr>
4474
4475         * src/gram.h (associativity): New enum type which replaces the
4476         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4477         `right_assoc', `left_assoc' and `non_assoc'.
4478         Adjust all dependencies.
4479         * src/reader.c: Formatting changes.
4480         (LTYPESTR): Don't define it, use it as a literal in
4481         `reader_output_yylsp'.
4482         * src/symtab.h (symbol_class): New enum type which replaces the
4483         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4484         `sunknown', `stoken and `snterm'.
4485
4486 2000-10-02  Akim Demaille  <akim@epita.fr>
4487
4488         * src/getargs.c (fixed_outfiles): Rename as...
4489         (yaccflag): for consistency and accuracy.
4490         Adjust dependencies.
4491
4492 2000-10-02  Akim Demaille  <akim@epita.fr>
4493
4494         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4495         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4496         difficult and introduced a lot of core dump.  It turns out that
4497         Bison used an implementation of `xmalloc' based on `calloc', and
4498         at various places it does depend upon the initialization to 0.  I
4499         have not tried to isolate the pertinent places, and all the former
4500         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4501         someone should address this issue.
4502
4503         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4504         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4516 2000-10-02  Akim Demaille  <akim@epita.fr>
4517
4518         * src/state.h (nstates, final_state, first_state, first_shift)

4597
4598         * src/output.c (token_actions): Introduce a temporary array,

4600         output_short_table.
4601
4602 2000-10-02  Akim Demaille  <akim@epita.fr>
4603
4604         `user_toknums' is output as a `short[]' in `output.c', while it is
4605         defined as a `int[]' in `reader.c'.  For consistency with the
4606         other output tables, `user_toknums' is now defined as a table of
4607         shorts.
4608
4609         * src/reader.c (user_toknums): Be a short table instead of an int

4622         order to get rid of the `static' prototypes.
4623         No longer use `register'.
4624         * src/output.h: New file.

4649         Don't define PARAMS.
4650         * src/system.h: Define PARAMS.
4651         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4652         purpose of config.h.  system.h must not try to fix wrong

4816
4817 2000-03-17  Akim Demaille  <akim@epita.fr>
4818
4819         On syntax errors, report the token on which we choked.
4820

4839

4841         copy_comment.  Removed now unused `match', `ended',
4842         `cplus_comment'.
4843         (copy_comment, copy_string): Moved, to be visible from
4844         copy_definition.
4845

4847

4870
4871         Change the handling of @s so that they behave exactly like $s.
4872         There is now a pseudo variable @$ (readble and writable), location
4873         of the lhs of the rule (by default ranging from the location of
4874         the first symbol of the rhs, to the location of the last symbol,
4875         or, if the rhs is empty, YYLLOC).
4876
4877         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4878         yyval.
4879         (yyparse): When providing a default semantic action, provide a
4880         default location action.
4881         (after the $): No longer change `*YYLSP', just stack YYLOC the
4882         same way you stack YYVAL.
4883         * src/reader.c (read_declarations): Use warns.
4884         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4885         (copy_action, case '@'): Likewise.
4886         Use a standard error message, to save useless work from
4887         translators.
4888
4889 2000-03-17  Akim Demaille  <akim@epita.fr>
4890

4908
4909         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4910         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4911         One `#if YYDEBUG' remains, since it uses variables which are
4912         defined only if `YYDEBUG != 0'.
4913
4914 2000-03-16  Akim Demaille  <akim@epita.fr>

4938         handled via src/Makefile.am.

4940         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

4946         the proper line number and file name.
4947         (DEFS): Propagate the location of bison library files and of the
4948         locale files.
4949         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4950         builddir.
4951         * acinclude.m4: Remove, replaced by the directory m4.
4952         * m4/Makefile.am (EXTRA_DIST): New variable.
4953         * m4/gettext.m4: New file, from the fileutils.

5640         major changes to files.c.
