  64
  65 2002-02-14  Paul Eggert  <eggert@twinsun.com>
  66
  67         Remove the support for C++ namespace cleanliness; it was
  68         causing more problems than it was curing, since it didn't work
  69         properly on some nonstandard C++ compilers.  This can wait
  70         for a proper C++ parser.
  71
  72         * NEWS: Document this.
  73         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
  74         of C++, as it's treated like C now.

  76         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):

  78         namespace cleanliness.
  79
  80 2002-02-14  Akim Demaille  <akim@epita.fr>
  81
  82         * tests/regression.at (else): Adjust to Andreas' change.

  89
  90         * src/output.c (output_rule_data): Don't output NULL, it might
  91         not be defined yet.

  94

 109
 110         * tests/input.at: New.
 111
 112 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 113
 114         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 115         more consistent when naming methods and variables.  Put preprocessor
 116         directives around tables only needed for debugging.
 117
 118 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 119
 120         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

 138 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 139
 140         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 141         not expanded by m4.
 142
 143 2002-02-05  Akim Demaille  <akim@epita.fr>
 144
 145         * data/bison.c++: Adjust to the M4 back end.
 146         More is certainly needed.

 148 2002-02-05  Akim Demaille  <akim@epita.fr>
 149
 150         Give a try to M4 as a back end.
 151
 152         * lib/readpipe.c: New, from wdiff.
 153         * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
 154         BISON_HAIRY.
 155         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 156         specific values.  Now it is m4 that performs the lookup.
 157         * src/parse-skel.y: Remove.
 158         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 159         * src/output.c (actions_output, guards_output)
 160         (token_definitions_output): No longer keeps track of the output
 161         line number, hence remove the second argument.
 162         (guards_output): Check against the guard member of a rule, not the
 163         action member.
 164         Adjust callers.
 165         (output_skeleton): Don't look for the skeleton location, let m4 do
 166         that.
 167         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 168         file will be used.
 169         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 170         (prepare): Given that for the time being changesyntax is not
 171         usable in M4, rename the muscles using `-' to `_'.
 172         Define `defines_flag', `output_parser_name' and `output_header_name'.
 173         * src/output.h (actions_output, guards_output)
 174         (token_definitions_output): Adjust prototypes.
 175         * src/scan-skel.l: Instead of scanning the skeletons, it now
 176         processes the output of m4: `__oline__' and `#output'.
 177         * data/bison.simple: Adjust to be used by M4(sugar).
 178         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 179         to date.
 180         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 181         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 182         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 183         shamelessly stolen from CVS Autoconf.

 197

 199         * data/: here.
 200
 201 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 202
 203         * src/bison.simple (YYSIZE_T): Do not define merely because
 204         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 205         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 206
 207 2002-01-27  Akim Demaille  <akim@epita.fr>
 208
 209         Fix `%nonassoc and eof'.
 210
 211         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 212         which were not properly copied!  Replace
 213         memcpy (res->errs, src->errs, src->nerrs);
 214         with
 215         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 216         !!!
 217         * tests/regression.at (%nonassoc and eof): Adjust to newest
 218         Autotest: `.' is not in the PATH.

 221
 222         * tests/sets.at (AT_EXTRACT_SETS): New.

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

 319

 337
 338         * src/reader.c (parse_braces): Don't fetch the next char, the

 380
 381         * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
 382         The ISO C++ standard is extremely clear about it: stderr is
 383         considered a macro, not a regular symbol (see table 94 `Header
 384         <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
 385         Therefore std:: does not apply to it.  It still does with fprintf.
 386         Also, s/cstdio.h/cstdio/.
 387
 388 2002-01-03  Akim Demaille  <akim@epita.fr>
 389
 390         * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
 391         for non system headers.
 392
 393 2002-01-02  Akim Demaille  <akim@epita.fr>
 394
 395         Equip the skeleton chain with location tracking, runtime trace,
 396         pure parser and scanner.
 397
 398         * src/parse-skel.y: Request a pure parser, locations, and prefix
 399         renaming.
 400         (%union): Having several members with the same type does not help
 401         type mismatches, simplify.
 402         (YYPRINT, yyprint): New.
 403         (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
 404         (skel_error): this.
 405         Handle locations.
 406         * src/scan-skel.l: Adjust to these changes.
 407         * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
 408         (LOCATION_PRINT, skel_control_t): New.
 409
 410 2001-12-30  Akim Demaille  <akim@epita.fr>
 411
 412         * src/parse-skel.y: Get rid of the shift/reduce conflict:
 413         replace `gb' with BLANKS.
 414         * src/scan-skel.l: Adjust.
 415
 416 2001-12-30  Akim Demaille  <akim@epita.fr>
 417
 418         * src/system.h: We don't need nor want bcopy.
 419         Throw away MS-DOS crap: we don't need getpid.
 420         * configure.in: We don't need strndup.  It was even causing
 421         problems: because Flex includes the headers *before* us,
 422         _GNU_SOURCE is not defined by config.h, and therefore strndup was
 423         not visible.
 424         * lib/xstrndup.c: New.
 425         * src/scan-skel.l: Use it.
 426         Be sure to initialize yylval.muscle member when scanning a MUSCLE.
 427         * src/parse-skel.y: Use %directives instead of #defines.
 428
 429 2001-12-30  Akim Demaille  <akim@epita.fr>
 430
 431         * src/skeleton.h: New.
 432         * src/output.c (output_parser, output_master_parser): Remove, dead
 433         code.
 434         * src/output.h (get_lines_number, actions_output, guards_output)
 435         (token_definitions_output): Prototype them.
 436         * src/parse-skel.y: Add the license notice.
 437         Include output.h and skeleton.h.
 438         (process_skeleton): Returns void, and takes a single parameter.
 439         * src/scan-skel.l: Add the license notice.
 440         Include skeleton.h.
 441         Don't use %option yylineno: it seems that then Flex imagines
 442         REJECT has been used, and therefore it won't reallocate its
 443         buffers (which makes no other sense to me than a bug).  It results
 444         in warnings for `unused: yy_flex_realloc'.
 445
 446 2001-12-30  Robert Anisko  <robert.anisko@epita.fr>
 447
 448         * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 449         (MUSCLE_INSERT_PREFIX): ...to there.
 450         * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
 451         (MUSCLE_INSERT_PREFIX): Move from here...
 452
 453         * src/bison.hairy: Add a section directive.  Put braces around muscle
 454         names.  This parser skeleton is still broken, but Bison should not
 455         choke on a bad muscle 'syntax'.
 456         * src/bison.simple: Add a section directive.  Put braces around muscle
 457         names.
 458
 459         * src/files.h (strsuffix, stringappend): Add declarations.
 460         (tab_extension): Add declaration.
 461         (short_base_name): Add declaration.
 462
 463         * src/files.c (strsuffix, stringappend): No longer static.  These
 464         functions are used in the skeleton parser.
 465         (tab_extension): New.
 466         (compute_base_names): Use the computations done in this function
 467         to guess if the generated parsers should have '.tab' in their
 468         names.
 469         (short_base_name): No longer static.
 470
 471         * src/output.c (output_skeleton): New.
 472         (output): Disable call to output_master_parser, and give a try to
 473         a new skeleton handling system.
 474         (guards_output, actions_output): No longer static.
 475         (token_definitions_output, get_lines_number): No longer static.
 476
 477         * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
 478
 479         * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
 480         parse-skel.y.
 481
 482         * src/parse-skel.y: New file.
 483         * src/scan-skel.l: New file.
 484
 485 2001-12-29  Akim Demaille  <akim@epita.fr>
 486
 487         %name-prefix is broken.
 488
 489         * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
 490         Adjust all dependencies.
 491         * tests/headers.at (export YYLTYPE): Strengthen this test: use
 492         %name-prefix.
 493
 494         Renaming yylval but not yylloc is not consistent.  Now we do.
 495
 496         * src/bison.simple: Prefix yylloc if used.
 497         * doc/bison.texinfo (Decl Summary): Document that.
 498
 499 2001-12-29  Akim Demaille  <akim@epita.fr>
 500
 501         * doc/bison.texinfo: Promote `%long-directive' over
 502         `%long_directive'.
 503         Remove all references to fixed-output-files, yacc is enough.
 504
 505 2001-12-29  Akim Demaille  <akim@epita.fr>
 506
 507         * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
 508         user prologue.  These are defaults.
 509         * tests/actions.at (Mid-rule actions): Make sure the user can
 510         define YYDEBUG and YYERROR_VERBOSE.
 511
 512 2001-12-29  Akim Demaille  <akim@epita.fr>
 513
 514         * src/output.c (header_output): Don't forget to export YYLTYPE and
 515         yylloc.
 516         * tests/headers.at (export YYLTYPE): New, make sure it does.
 517         * tests/regression.at (%union and --defines, Invalid CPP headers):
 518         Move to...
 519         * tests/headers.at: here.
 520
 521 2001-12-29  Akim Demaille  <akim@epita.fr>
 522
 523         * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
 524
 525 2001-12-29  Akim Demaille  <akim@epita.fr>
 526
 527         * tests/actions.at (Mid-rule actions): Output on a single line
 528         instead of several.
 529
 530 2001-12-29  Akim Demaille  <akim@epita.fr>
 531
 532         * doc/bison.texinfo: Formatting changes.
 533
 534 2001-12-29  Akim Demaille  <akim@epita.fr>
 535
 536         Don't store the token defs in a muscle, just be ready to output it
 537         on command.  Now possible via `symbols'.  Fixes a memory leak.
 538
 539         * src/output.c (token_definitions_output): New.
 540         (output_parser, header_output): Use it.
 541         * src/reader.c (symbols_save): Remove.
 542
 543 2001-12-29  Akim Demaille  <akim@epita.fr>
 544
 545         * src/bison.simple: Do not provide a default for YYSTYPE and
 546         YYLTYPE before the user's prologue.  Otherwise it's hardly... a
 547         default.
 548
 549 2001-12-29  Akim Demaille  <akim@epita.fr>
 550
 551         Mid-rule actions are simply... ignored!
 552
 553         * src/reader.c (readgram): Be sure to attach mid-rule actions to
 554         the empty-rule associated to the dummy symbol, not to the host
 555         rule.
 556         * tests/actions.at (Mid-rule actions): New.
 557
 558 2001-12-29  Akim Demaille  <akim@epita.fr>
 559
 560         Memory leak.
 561
 562         * src/reader.c (reader): Free grammar.
 563
 564 2001-12-29  Akim Demaille  <akim@epita.fr>
 565
 566         Memory leak.
 567
 568         * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
 569         since it allocates it for each state, although only one is needed.
 570         (allocate_storage): Do it here.
 571
 572 2001-12-29  Akim Demaille  <akim@epita.fr>
 573
 574         * src/options.h, src/options.c (create_long_option_table): Rename
 575         as...
 576         (long_option_table_new): this, with a clearer prototype.
 577         (percent_table): Remove, unused,
 578         * src/getargs.c (getargs): Adjust.
 579
 580 2001-12-29  Akim Demaille  <akim@epita.fr>
 581
 582         * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
 583         * src/print.c, src/print_graph.c, src/state.h: Rename state_table
 584         as states.
 585
 586 2001-12-29  Akim Demaille  <akim@epita.fr>
 587
 588         * src/lalr.c (build_relations): Rename `states' as `states1'.
 589         Sorry, I don't understand exactly what it is, no better name...
 590
 591 2001-12-29  Akim Demaille  <akim@epita.fr>
 592
 593         * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
 594         * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
 595         * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
 596         as rules.
 597
 598 2001-12-29  Akim Demaille  <akim@epita.fr>
 599
 600         * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
 601         ago.
 602
 603 2001-12-29  Akim Demaille  <akim@epita.fr>
 604
 605         * src/reader.c, src/reader.h (user_toknums): Remove.
 606         Adjust all users to use symbols[i]->user_token_number.
 607
 608 2001-12-29  Akim Demaille  <akim@epita.fr>
 609
 610         * src/gram.c, src/gram.h (sprec, sassoc): Remove.
 611         Adjust all users to use symbols[i]->prec or ->assoc.
 612
 613 2001-12-29  Akim Demaille  <akim@epita.fr>
 614
 615         * src/reader.c, src/reader.h (tags): Remove.
 616         Adjust all users to use symbols[i]->tag.
 617
 618 2001-12-29  Akim Demaille  <akim@epita.fr>
 619
 620         * src/gram.h, src/gram.c (symbols): New, similar to state_table
 621         and rule_table.
 622         * src/reader.c (packsymbols): Fill this table.
 623         Drop sprec.
 624         * src/conflicts.c (resolve_sr_conflict): Adjust.
 625         * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
 626         single table.
 627         Use symbols[i]->tag instead of tags[i].
 628
 629 2001-12-29  Akim Demaille  <akim@epita.fr>
 630
 631         * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
 632         In addition, put a comment in there, to replace...
 633         * tests/regression.at (%union and C comments): Remove.
 634
 635 2001-12-29  Akim Demaille  <akim@epita.fr>
 636
 637         * tests/regression.at (Web2c Actions): Blindly move the actual
 638         output as expected output.  The contents *seem* right to me, but I
 639         can't pretend reading perfectly parser tables...  Nonetheless, all
 640         the other tests pass correctly, the table look OK, even though the
 641         presence of `$axiom' is to be noted: AFAICS it is useless (but
 642         harmless).
 643
 644 2001-12-29  Akim Demaille  <akim@epita.fr>
 645
 646         * src/reader.c (readgram): Don't add the rule 0 if there were no
 647         rules read.  In other words, add it _after_ having performed
 648         grammar sanity checks.
 649         Fixes the `tests/regression.at (Invalid input: 1)' Failure.
 650
 651 2001-12-29  Akim Demaille  <akim@epita.fr>
 652
 653         * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
 654         visible, and some states have now a different number.
 655
 656 2001-12-29  Akim Demaille  <akim@epita.fr>
 657
 658         * src/reader.c (readgram): Bind the initial rule's lineno to that
 659         of the first rule.
 660         * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
 661         (Solved SR Conflicts): Adjust rule 0's line number.
 662
 663 2001-12-29  Akim Demaille  <akim@epita.fr>
 664
 665         Fix the `GAWK Grammar' failure.
 666
 667         * src/LR0.c (final_state): Initialize to -1 so that we do compute
 668         the reductions of the first state which was mistakenly confused
 669         with the final state because precisely final_state was initialized
 670         to 0.
 671         * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
 672         now noticed by Bison.
 673         * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
 674         have a reduction on $default.
 675
 676 2001-12-29  Akim Demaille  <akim@epita.fr>
 677
 678         * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
 679         rule line numbers.
 680         * src/closure.c (print_closure): Likewise.
 681         * src/derives.c (print_derives): Likewise.
 682         * tests/sets.at (Nullable): Adjust: the rule numbers are correct
 683         now.
 684
 685 2001-12-29  Akim Demaille  <akim@epita.fr>
 686
 687         * src/lalr.c (lookaheads_print): New.
 688         (lalr): Call it when --trace-flag.
 689         * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
 690         are dumped.
 691
 692 2001-12-29  Akim Demaille  <akim@epita.fr>
 693
 694         * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
 695         when walking through ritem, even via rule->rhs.
 696         * src/reduce.c (dump_grammar, useful_production, reduce_output)
 697         (useful_production, useless_nonterminals): Likewise.
 698         (reduce_grammar_tables): Likewise, plus update nritems.
 699         * src/nullable.c (set_nullable): Likewise.
 700         * src/lalr.c (build_relations): Likewise.
 701         * tests/sets.at (Nullable): Adjust.
 702         Fortunately, now, the $axiom is no longer nullable.
 703
 704 2001-12-29  Akim Demaille  <akim@epita.fr>
 705
 706         * src/LR0.c (generate_states): Use nritems, not nitems, nor using
 707         the 0-sentinel.
 708         * src/gram.c (ritem_longest_rhs): Likewise.
 709         * src/reduce.c (nonterminals_reduce): Likewise.
 710         * src/print_graph.c (print_graph): Likewise.
 711         * src/output.c (output_rule_data): Likewise.
 712         * src/nullable.c (set_nullable):  Likewise.
 713
 714 2001-12-29  Akim Demaille  <akim@epita.fr>
 715
 716         * src/output.c: Comment changes.
 717
 718 2001-12-27  Paul Eggert  <eggert@twinsun.com>
 719
 720         * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
 721         cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
 722         Sparc, as they were causing more porting problems than the
 723         (minor) performance improvement was worth.
 724
 725         Also, catch up with 1.31's YYSTD.
 726
 727 2001-12-27  Akim Demaille  <akim@epita.fr>
 728
 729         * src/output.c (output_gram): Rely on nritems, not the
 730         0-sentinel.  See below.
 731         Use -1 as separator, not 0.
 732         * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
 733         Rely on -1 as separator in yyrhs, instead of 0.
 734         * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
 735         twice `Now at end of input', therefore there are two lines less to
 736         expect.
 737
 738 2001-12-27  Akim Demaille  <akim@epita.fr>
 739
 740         * tests/regression.at (Unresolved SR Conflicts):
 741         (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
 742         below.
 743
 744 2001-12-27  Akim Demaille  <akim@epita.fr>
 745
 746         * src/LR0.c (new_state): Recognize the final state by the fact it
 747         is reached by eoftoken.
 748         (insert_start_shifting_state, insert_eof_shifting_state)
 749         (insert_accepting_state, augment_automaton): Remove, since now
 750         these states are automatically computed from the initial state.
 751         (generate_states): Adjust.
 752         * src/print.c: When reporting a rule number to the user, substract
 753         1, so that the axiom rule is rule 0, and the first user rule is 1.
 754         * src/reduce.c: Likewise.
 755         * src/print_graph.c (print_core): For the time being, just as for
 756         the report, depend upon --trace-flags to dump the full set of
 757         items.
 758         * src/reader.c (readgram): Once the grammar read, insert the rule
 759         0: `$axiom: START-SYMBOL $'.
 760         * tests/set.at: Adjust: rule 0 is now displayed, and since the
 761         number of the states has changed (the final state is no longer
 762         necessarily the last), catch up.
 763
 764 2001-12-27  Akim Demaille  <akim@epita.fr>
 765
 766         Try to make the use of the eoftoken valid.  Given that its value
 767         is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
 768         is used instead of > 0 where appropriate, (ii), depend upon nritems
 769         instead of the 0-sentinel.
 770
 771         * src/gram.h, src/gram.c (nritems): New.
 772         Expected to be duplication of nitems, but for the time being...
 773         * src/reader.c (packgram): Assert nritems and nitems are equal.
 774         * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
 775         * src/closure.c (print_closure, print_fderives): Likewise.
 776         * src/gram.c (ritem_print): Likewise.
 777         * src/print.c (print_core, print_grammar): Likewise.
 778         * src/print_graph.c: Likewise.
 779
 780 2001-12-27  Akim Demaille  <akim@epita.fr>
 781
 782         * src/main.c (main): If there are complains after grammar
 783         reductions, then output the report anyway if requested, then die.
 784         * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
 785         * src/reader.c (eoftoken): New.
 786         (parse_token_decl): If the token being defined has value `0', it
 787         is the eoftoken.
 788         (packsymbols): No longer hack `tags' to insert `$' by hand.
 789         Be sure to preserve the value of the eoftoken.
 790         (reader): Make sure eoftoken is defined.
 791         Initialize nsyms to 0: now eoftoken is created just like the others.
 792         * src/print.c (print_grammar): Don't special case the eof token.
 793         * src/regression.at: Adjust: `$' has value 0, not -1, which was a
 794         lie anyway, albeit pleasant.
 795         * tests/calc.at: Exercise error messages with eoftoken.
 796         Change the grammar so that empty input is invalid.
 797         Adjust expectations.
 798         When yyungeting, be sure to use a valid yylloc: use last_yylloc.
 799
 800 2001-12-27  Akim Demaille  <akim@epita.fr>
 801
 802         * configure.in: Check the protos of strchr ans strspn.
 803         Replace strchr if needed.
 804         * src/system.h: Provide the protos of strchr, strspn and memchr if
 805         missing.
 806         * lib/strchr.c: New.
 807         * src/reader.c (symbols_save): Use strchr.
 808
 809 2001-12-27  Akim Demaille  <akim@epita.fr>
 810
 811         * src/print.c, src/print_graph.c (escape): New.
 812         Use it to quote the TAGS outputs.
 813         * src/print_graph.c (print_state): Now errors are in red, and
 814         reductions in green.
 815         Prefer high to wide: output the state number on a line of its own.
 816
 817 2001-12-27  Akim Demaille  <akim@epita.fr>
 818
 819         * src/state.h, src/state.c (reductions_new): New.
 820         * src/LR0.c (set_state_table): Let all the states have a
 821         `reductions', even if reduced to 0.
 822         (save_reductions): Adjust.
 823         * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
 824         * src/print.c (print_reductions, print_actions): Adjust.
 825         * src/output.c (action_row): Adjust.
 826
 827 2001-12-27  Akim Demaille  <akim@epita.fr>
 828
 829         * src/state.h, src/state.c (errs_new, errs_dup): New.
 830         * src/LR0.c (set_state_table): Let all the states have an errs,
 831         even if reduced to 0.
 832         * src/print.c (print_errs, print_reductions): Adjust.
 833         * src/output.c (output_actions, action_row): Adjust.

 837
 838         * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
 839
 840 2001-12-27  Akim Demaille  <akim@epita.fr>
 841
 842         * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
 843         * src/print.c: here.
 844         (lookaheadset, shiftset): New, used as additional storage by
 845         print_reductions.
 846         (print_results): Adjust.
 847         (print_shifts, print_gotos, print_errs): New, extracted from...
 848         (print_actions): here.
 849         * src/print_graph.c (print_actions): Remove dead code.
 850
 851 2001-12-27  Akim Demaille  <akim@epita.fr>
 852
 853         * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
 854         `$n' and `@n'.
 855
 856 2001-12-27  Akim Demaille  <akim@epita.fr>
 857
 858         * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
 859         (build_relations): Adjust.
 860
 861 2001-12-27  Akim Demaille  <akim@epita.fr>
 862
 863         * src/lalr.c (set_goto_map): Remove a wrong but benign loop
 864         duplication.
 865
 866 2001-12-27  Akim Demaille  <akim@epita.fr>
 867
 868         * src/reader.c (packgram): Catch nitems overflows.
 869
 870 2001-12-27  Akim Demaille  <akim@epita.fr>
 871
 872         * src/files.c, src/files.h (guard_obstack): Remove.
 873         * src/output.c (output): Adjust.
 874         * src/reader.c (parse_braces): New, factoring...
 875         (copy_action, copy_guard): these two which are renamed as...
 876         (parse_action, parse_guard): these.
 877         As a voluntary consequence, using braces around guards is now
 878         mandatory.
 879
 880 2001-12-27  Akim Demaille  <akim@epita.fr>
 881
 882         * src/gram.h (rule_t): `guard' and `guard_line' are new members.
 883         * src/reader.c (symbol_list): `guard' and `guard_line' are new
 884         members.
 885         (symbol_list_new): Adjust.
 886         (copy_action): action_line is the first line, not the last.
 887         (copy_guard): Just as for actions, store the `action' only, not
 888         the switch/case/break flesh.
 889         Don't parse the user action that might follow the guard, let...
 890         (readgram): do it, i.e., now, there can be an action after a
 891         guard.
 892         In other words the guard is just explicitly optional.
 893         (packgram): Adjust.
 894         * src/output.c (guards_output): New.
 895         (output_parser): Call it when needed.
 896         (output): Also free the guard and attrs obstacks.
 897         * src/files.c, src/files.h (obstack_save): Remove.
 898         (output_files): Remove.
 899         As a result, if one needs the former `.act' file, using an
 900         appropriate skeleton which requires actions and guards is now
 901         required.
 902         * src/main.c (main): Adjust.
 903         * tests/semantic.at: New.
 904         * tests/regression.at: Use `input.y' as input file name.
 905         Avoid 8+3 problems by requiring input.c when the test needs the
 906         parser.
 907
 908 2001-12-27  Akim Demaille  <akim@epita.fr>
 909
 910         * src/reader.c (symbol_list_new): Be sure to initialize all the
 911         fields.
 912
 913 2001-12-27  Akim Demaille  <akim@epita.fr>
 914
 915         All the hacks using a final pseudo state are now useless.
 916
 917         * src/LR0.c (set_state_table): state_table holds exactly nstates.
 918         * src/lalr.c (nLA): New.
 919         (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
 920         instead of lookaheadsp from the pseudo state (nstate + 1).
 921
 922 2001-12-27  Akim Demaille  <akim@epita.fr>
 923
 924         * src/output.c (action_row, token_actions): Use a state_t instead
 925         of a integer, and nlookaheads instead of the following state's
 926         lookaheadsp.
 927
 928 2001-12-27  Akim Demaille  <akim@epita.fr>
 929

 932         (count_sr_conflicts, count_rr_conflicts, conflicts_output)
 933         (conflicts_print, print_reductions): Use a state_t instead of an
 934         integer when referring to a state.
 935         As much as possible, depend upon nlookaheads, instead of the
 936         `lookaheadsp' member of the following state (since lookaheads of
 937         successive states are successive, the difference between state n + 1
 938         and n served as the number of lookaheads for state n).
 939         * src/lalr.c (add_lookback_edge): Likewise.
 940         * src/print.c (print_core, print_actions, print_state)
 941         (print_results): Likewise.
 942         * src/print_graph.c (print_core, print_actions, print_state)
 943         (print_graph): Likewise.
 944         * src/conflicts.h: Adjust.

 946 2001-12-27  Akim Demaille  <akim@epita.fr>
 947
 948         * src/bison.hairy: Formatting/comment changes.
 949         ANSIfy.
 950         Remove `register' indications.
 951         Add plenty of `static'.
 952
 953 2001-12-27  Akim Demaille  <akim@epita.fr>
 954
 955         * src/output.c (prepare): Drop the muscle `ntbase' which
 956         duplicates ntokens.
 957         * src/bison.simple: Formatting/comment changes.
 958         Use YYNTOKENS only, which is documented, but not YYNTBASE, which
 959         is an undocumented synonym.
 960
 961 2001-12-22  Akim Demaille  <akim@epita.fr>
 962
 963         * src/output.c (output_table_data): Change the prototype to use
 964         `int' for array ranges: some invocations do pass an int, not a
 965         short.
 966         Reported by Wayne Green.

 974         * tests/regression.at (Web2c): Rename as...
 975         (Web2c Report): this.
 976         (Web2c Actions): New.
 977
 978 2001-12-22  Akim Demaille  <akim@epita.fr>
 979
 980         Reductions in web2c.y are improperly reported.
 981         Reported by Mike Castle.

 984         * tests/regression.at (Web2c): New.
 985
 986 2001-12-18  Akim Demaille  <akim@epita.fr>
 987
 988         Some host fail on `assert (!"foo")', which expands to
 989         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
 990         Reported by Nelson Beebee.
 991
 992         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
 993         `#define it_succeeded 0' and `assert (it_succeeded)'.
 994
 995 2001-12-17  Marc Autret  <autret_m@epita.fr>
 996
 997         * src/bison.simple: Don't hard code the skeleton line and filename.
 998         * src/output.c (output_parser): Rename 'line' as 'output_line'.
 999         New line counter 'skeleton_line' (skeleton-line muscle).
1000
1001 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1002
1003         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1004         YYDEBUG must be defined to a nonzero value.
1005
1006         * src/bison.simple (yytname): Do not assume that the user defines
1007         YYDEBUG to a properly parenthesized expression.
1008
1009 2001-12-17  Akim Demaille  <akim@epita.fr>
1010
1011         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1012         nlookaheads is a new member.
1013         Adjust all users.
1014         * src/lalr.h (nlookaheads): Remove this orphan declaration.

1016         state.

1026
1027         * src/conflicts.c (print_reductions): Formatting changes.
1028
1029 2001-12-17  Akim Demaille  <akim@epita.fr>
1030
1031         * src/conflicts.c (flush_shift): Also adjust lookaheadset.

1034
1035 2001-12-17  Akim Demaille  <akim@epita.fr>
1036
1037         * src/output.c (output_obstack): Be static and rename as...

1039         output_obstack.
1040         * src/reader.h (muscle_obstack): Move to...
1041         * src/output.h: here, since it's defined in output.c.

1045         * src/output.c (action_row, save_column, default_goto)

1047         locality.
1048
1049 2001-12-17  Akim Demaille  <akim@epita.fr>

1052
1053 2001-12-17  Akim Demaille  <akim@epita.fr>
1054
1055         * src/files.c (output_files): Free the output_obstack.

1062
1063         * src/output.c (actions_output): Fix. When we use %no-lines,
1064         there is one less line per action.
1065
1066 2001-12-16  Marc Autret  <autret_m@epita.fr>
1067
1068         * src/bison.simple: Remove a useless #line directive.
1069         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1070         * src/output.c (get_lines_number): New.
1071         (output_parser): Adjust, now takes care about the lines of a
1072         output muscles.
1073         Fix line numbering.
1074         (actions_output): Computes the number of lines taken by actions.
1075         (output_master_parser): Insert new skeleton which is the name of
1076         the output parser file name.
1077
1078 2001-12-15  Marc Autret  <autret_m@epita.fr>

1085
1086 2001-12-15  Akim Demaille  <akim@epita.fr>
1087
1088         Make `make distcheck' work.
1089
1090         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1091         system.h which uses libgettext.h.
1092
1093 2001-12-15  Akim Demaille  <akim@epita.fr>
1094
1095         * src/nullable.c (set_nullable): Useless rules must be skipped,
1096         otherwise, since we range over their symbols, we might look at a
1097         nonterminal which no longer ``exists'', i.e., it is not counted in
1098         `nvars', hence we overflow our arrays.

1106         (compute_header_macro): Global.
1107         (defines_obstack_save): Remove.
1108         * src/reader.c (parse_union_decl): No longer output to
1109         defines_obstack: its content can be found in the `stype' muscle
1110         anyway.
1111         (output_token_translations): Merge into...
1112         (symbols_output): this.

1120
1121         * src/reader.c (parse_union_decl): Instead of handling two obstack
1122         simultaneously, use one to define the `stype' muscle, and use the
1123         value of the latter to fill defines_obstack.
1124         (copy_comment): Remove.
1125         (copy_comment2): Work for a single obstack.
1126         Rename as...
1127         (copy_comment): this.

1130
1131         * src/lex.c, src/lex.h (xgetc): No longer static.
1132         * src/reader.c (parse_union_decl): Revamp.
1133
1134 2001-12-15  Akim Demaille  <akim@epita.fr>
1135
1136         Still making progress in separating Bison into (i) input, (ii)
1137         process, (iii) output: now we can directly output the parser file
1138         without using table_obstack at all.
1139
1140         * src/files.c, src/files.h (table_obstack): Bye bye.
1141         (parser_file_name): New.
1142         * src/files.c (compute_output_file_names): Compute it.
1143         * src/output.c (actions_output, output_parser)
1144         (output_master_parser): To a file instead of an obstack.
1145
1146 2001-12-15  Akim Demaille  <akim@epita.fr>
1147
1148         Attach actions to rules, instead of pre-outputting them to
1149         actions_obstack.
1150
1151         * src/gram.h (rule_t): action and action_line are new members.
1152         * src/reader.c (symbol_list): Likewise.
1153         (copy_action): Save the actions within the rule.
1154         (packgram): Save them in rule_table.
1155         * src/output.c (actions_output): New.
1156         (output_parser): Use it on `%%actions'.
1157         (output_rule_data): Don't free rule_table.
1158         (output): Do it.
1159         (prepare): Don't save the `action' muscle.
1160         * src/bison.simple: s/%%action/%%actions/.
1161
1162 2001-12-15  Akim Demaille  <akim@epita.fr>
1163
1164         * src/reader.c (copy_action): When --yacc, don't append a `;'
1165         to the user action: let it fail if lacking.
1166         Suggested by Arnold Robbins and Tom Tromey.
1167
1168 2001-12-14  Akim Demaille  <akim@epita.fr>
1169
1170         * src/lex.c (literalchar): Simply return the char you decoded, non
1171         longer mess around with obstacks and int pointers.
1172         Adjust all callers.
1173
1174 2001-12-14  Akim Demaille  <akim@epita.fr>
1175
1176         * src/lex.c (literalchar): Don't escape the special characters,
1177         just decode them, and keep them as char (before, eol was output as
1178         the 2 char string `\n' etc.).
1179         * src/output.c (output_rule_data): Use quotearg to output the
1180         token strings.
1181
1182 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1183
1184         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1185         Do not infringe on the global user namespace when using C++.
1186         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1187         All uses of `fprintf' and `stderr' changed.
1188
1189         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1190
1191 2001-12-13  Akim Demaille  <akim@epita.fr>
1192
1193         The computation of nullable is broken: it doesn't handle empty
1194         RHS's properly.
1195
1196         * tests/torture.at (GNU AWK Grammar): New.
1197         * tests/sets.at (Nullable): New.
1198         * src/nullable.c (set_nullable): Instead of blindly looping over
1199         `ritems', loop over the rules, and then over their rhs's.
1200
1201         Work around Autotest bugs.
1202
1203         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1204         frame, because Autotest understand lines starting with a `+' as
1205         traces from the shell.  Then, they are not processed properly.
1206         Admittedly an Autotest bug, but we don't have time to wait for
1207         Autotest to catch up.
1208         * tests/regression.at (Broken Closure): Adjust to the new table
1209         frames.
1210         Move to...
1211         * tests/sets.at: here.
1212
1213 2001-12-13  Akim Demaille  <akim@epita.fr>
1214
1215         * src/closure.c (closure): Use nrules instead of playing tricks
1216         with BITS_PER_WORD.
1217
1218 2001-12-13  Akim Demaille  <akim@epita.fr>
1219
1220         * src/print.c (print_actions): Output the handling of `$' as the
1221         traces do: shifting the token EOF.  Before EOF was treated as a
1222         nonterminal.
1223         * tests/regression.at: Adjust some tests.
1224         * src/print_graph.c (print_core): Complete the set of items via
1225         closure.  The next-to-final and final states are still unsatisfying,
1226         but that's to be addressed elsewhere.
1227         No longer output the rule numbers, but do output the state number.
1228         A single loop for the shifts + gotos is enough, but picked a
1229         distinct color for each.
1230         (print_graph): Initialize and finalize closure.
1231
1232 2001-12-13  Akim Demaille  <akim@epita.fr>
1233
1234         * src/reader.c (readgram): Remove dead code, an strip useless
1235         braces.
1236         (get_type): Remove, unused.
1237
1238 2001-12-12  Akim Demaille  <akim@epita.fr>
1239
1240         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1241         on that of lib/error.c.
1242
1243 2001-12-12  Akim Demaille  <akim@epita.fr>
1244
1245         Some hosts don't like `/' in includes.
1246
1247         * src/system.h: Include libgettext.h without qualifying the path.
1248         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1249         $(top_srcdir).
1250
1251 2001-12-11  Marc Autret  <autret_m@epita.fr>
1252
1253         * src/output.c (output_parser): Remove useless muscle.
1254
1255 2001-12-11  Marc Autret  <autret_m@epita.fr>
1256
1257         * src/bison.simple: Remove #line just before %%epilogue. It
1258         is now handled in ...
1259         * src/reader.c (read_additionnal_code): Add the output of a
1260         #line for the epilogue.
1261
1262 2001-12-10  Marc Autret  <autret_m@epita.fr>
1263
1264         * src/reader.c (copy_definition): Re-use CPP-outed code which
1265         replace precedent remove.
1266         * src/bison.simple: Remove #line before %%prologue because
1267         %%input-line is wrong at this time.
1268
1269 2001-12-10  Marc Autret  <autret_m@epita.fr>
1270
1271         * src/reader.c (symbols_output): Clean up.
1272         * src/output.c (output_gram, output): Clean up.
1273
1274 2001-12-10  Akim Demaille  <akim@epita.fr>
1275
1276         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1277         * src/LR0.c (set_state_table): here.
1278         * src/lalr.c (lalr): Call it.
1279
1280 2001-12-10  Akim Demaille  <akim@epita.fr>
1281
1282         * src/state.h (shifts): Remove the `number' member: shifts are
1283         attached to state, hence no longer need to be labelled with a
1284         state number.
1285
1286 2001-12-10  Akim Demaille  <akim@epita.fr>
1287
1288         Now that states have a complete set of members, the linked list of
1289         shifts is useless: just fill directly the state's shifts member.
1290
1291         * src/state.h (shifts): Remove the `next' member.
1292         * src/LR0.c (first_state, last_state): Remove.
1293         Adjust the callers.
1294         (augment_automaton): Don't look for the shifts that must be added
1295         a shift on EOF: it is those of the state we looked for!  But now,
1296         since shifts are attached, it is no longer needed to looking
1297         merely by its id: its number.
1298
1299 2001-12-10  Akim Demaille  <akim@epita.fr>
1300
1301         * src/LR0.c (augment_automaton): Better variable locality.
1302         Remove an impossible branch: if there is a state corresponding to
1303         the start symbol being shifted, then there is shift for the start
1304         symbol from the initial state.
1305
1306 2001-12-10  Akim Demaille  <akim@epita.fr>
1307
1308         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1309         only when appropriate: when insert_start_shifting_state' is not
1310         invoked.
1311         * tests/regression.at (Rule Line Numbers): Adjust.
1312
1313 2001-12-10  Akim Demaille  <akim@epita.fr>
1314
1315         * src/LR0.c (augment_automaton): Now that all states have shifts,
1316         merge the two cases addition shifts to the initial state.
1317
1318 2001-12-10  Akim Demaille  <akim@epita.fr>
1319
1320         * src/lalr.c (set_state_table): Move to...
1321         * src/LR0.c: here.
1322         * src/lalr.c (lalr): Don't call it...
1323         * src/LR0.c (generate_states): do it.
1324         * src/LR0.h (first_state): Remove, only the table is used.
1325
1326 2001-12-10  Akim Demaille  <akim@epita.fr>
1327
1328         * src/LR0.h (first_shift, first_reduction): Remove.
1329         * src/lalr.c: Don't use first_shift: find shifts through the
1330         states.
1331
1332 2001-12-10  Akim Demaille  <akim@epita.fr>
1333
1334         * src/LR0.c: Attach shifts to states as soon as they are
1335         computed.
1336         * src/lalr.c (set_state_table): Instead of assigning shifts to
1337         state, just assert that the mapping was properly done.
1338
1339 2001-12-10  Akim Demaille  <akim@epita.fr>
1340
1341         * src/LR0.c (insert_start_shift): Rename as...
1342         (insert_start_shifting_state): this.
1343         (insert_eof_shifting_state, insert_accepting_state): New.
1344         (augment_automaton): Adjust.
1345         Better locality of the variables.
1346         When looking if the start_symbol is shifted from the initial
1347         state, using `while (... symbol != start_symbol ...)' sounds
1348         better than `while (... symbol < start_symbol ...)': If fail
1349         to see how the order between symbols could be relevant!
1350
1351 2001-12-10  Akim Demaille  <akim@epita.fr>
1352
1353         * src/getargs.h: Don't declare `spec_name_prefix' and
1354         `spec_file_prefix', declared by src/files.h.
1355         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1356         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1357         * src/output.c (prepare): Adjust.
1358         * src/reader.c (symbols_output): Likewise.
1359         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1360
1361 2001-12-10  Akim Demaille  <akim@epita.fr>
1362
1363         * src/muscle_tab.c (muscle_init): NULL is a better default than
1364         `"0"'.
1365
1366 2001-12-10  Akim Demaille  <akim@epita.fr>
1367
1368         * src/reader.c (reader): Calling symbols_output once is enough.
1369
1370 2001-12-10  Akim Demaille  <akim@epita.fr>
1371
1372         Now that states have a complete set of members, the linked list of
1373         reductions is useless: just fill directly the state's reductions
1374         member.
1375
1376         * src/state.h (struct reductions): Remove member `number' and
1377         `next'.
1378         * src/LR0.c (first_reduction, last_reduction): Remove.
1379         (save_reductions): Don't link the new reductions, store them in
1380         this_state.
1381         * src/lalr.c (set_state_table): No need to attach reductions to
1382         states, it's already done.
1383         * src/output.c (output_actions): No longer free the shifts, then
1384         the reductions, then the states: free all the states and their
1385         members.
1386
1387 2001-12-10  Akim Demaille  <akim@epita.fr>
1388
1389         * src/options.c (OPTN, DRTV, BOTH): New.
1390         (option_table): Use them.
1391
1392         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1393         the job of system.h.
1394         * src/options.c: Don't include stdio.h and xalloc.h for the same
1395         reasons.
1396
1397 2001-12-10  Akim Demaille  <akim@epita.fr>
1398
1399         * src/output.c (output, prepare): Make sure the values of the
1400         muscles `action' and `prologue' are 0-terminated.
1401
1402 2001-12-10  Akim Demaille  <akim@epita.fr>
1403
1404         Clean up GCC warnings.
1405
1406         * src/reader.c (copy_action): `buf' is not used.
1407         (parse_skel_decl): Be static.
1408         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1409         * src/options.h (create_long_option_table): Have a real prototype.
1410         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1411         (hash_delete_at): Return const void *.
1412         Adjust casts to preserve the const.
1413
1414 2001-12-10  Akim Demaille  <akim@epita.fr>
1415
1416         * configure.in: Require 2.52g.
1417         M4 is not needed, but AUTOM4TE is.
1418         * m4/m4.m4: Remove.
1419         * tests/Makefile.am: Adjust.
1420
1421 2001-12-10  Akim Demaille  <akim@epita.fr>
1422
1423         One structure for states is enough, even though theoretically
1424         there are LR(0) states and LALR(1) states.
1425
1426         * src/lalr.h (state_t): Remove.
1427         (state_table): Be state_t **, not state_t *.
1428         * src/state.h (core, CORE_ALLOC): Rename as...
1429         (state_t, STATE_ALLOC): this.
1430         Add the LALR(1) members: shifts, reductions, errs.
1431         * src/LR0.c (state_table): Rename as...
1432         (state_hash): this, to avoid name clashes with the global
1433         `state_table'.
1434         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1435         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

1439         Bison dumps core on bash.y.
1440         Reported by Pascal Bart.
1441
1442         * src/warshall.c (bitmatrix_print): New.
1443         (TC): Use it.
1444         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1445         j must be the outer loop.
1446         * tests/regression.at (Broken Closure): New.

1448 2001-12-05  Akim Demaille  <akim@epita.fr>
1449
1450         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1451         its argument.
1452         Reported by Peter Hámorský.

1456         * src/conflicts.c (err_table): Remove.
1457         (resolve_sr_conflict): Adjust.
1458         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1459         Rename as...
1460         (state_t.reductions, state_t.shifts): this.
1461
1462 2001-12-05  Akim Demaille  <akim@epita.fr>
1463
1464         * src/reduce.c (reduce_grammar_tables): No longer disable the
1465         removal of useless rules via CPP but via `if (0)', so that the
1466         compiler still check the code is valid.
1467         For instance, it should have noticed `rline' no longer exists: use
1468         the `line' member of rule_t.
1469         * src/gram.c (dummy, rline): Remove, unused.
1470
1471 2001-12-05  Akim Demaille  <akim@epita.fr>
1472
1473         * src/output.c (pack_vector): Use assert, not berror.
1474         * src/main.c (berror): Remove, unused.
1475
1476 2001-12-05  Akim Demaille  <akim@epita.fr>
1477
1478         New experimental feature: if --verbose --trace output all the
1479         items of a state, not only its kernel.
1480
1481         * src/print.c (print_core): If `trace_flag', then invoke closure
1482         before outputting the items of the state (print_core is no longer
1483         a correct name them).
1484         (print_results): Invoke new_closure/free_closure if needed.
1485
1486 2001-12-05  Akim Demaille  <akim@epita.fr>
1487
1488         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1489         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1490         (nitemset): for consistency with the rest of the project.
1491
1492 2001-12-05  Akim Demaille  <akim@epita.fr>
1493
1494         * src/closure.c (print_closure): Improve.
1495         (closure): Use it for printing input and output.
1496
1497 2001-12-05  Akim Demaille  <akim@epita.fr>
1498
1499         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1500         indexed by nonterminals.
1501
1502 2001-12-05  Akim Demaille  <akim@epita.fr>
1503
1504         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1505         what it was!).
1506         * src/warshall.h: Remove accidental duplication of the content.
1507
1508 2001-12-05  Akim Demaille  <akim@epita.fr>
1509
1510         * src/closure.c (set_fderives): De-obfuscate.
1511
1512 2001-12-05  Akim Demaille  <akim@epita.fr>
1513
1514         * src/closure.c (print_firsts, print_fderives): De-obfuscate.
1515
1516 2001-12-05  Akim Demaille  <akim@epita.fr>
1517
1518         * src/closure.c (set_firsts): De-obfuscate.
1519
1520 2001-12-05  Akim Demaille  <akim@epita.fr>
1521
1522         * src/output.c (action_row): De-obfuscate
1523         using the good o' techniques: arrays not pointers, variable
1524         locality, BITISSET, RESETBIT etc.
1525
1526 2001-12-05  Akim Demaille  <akim@epita.fr>
1527
1528         Pessimize the code to simplify it: from now on, all the states
1529         have a valid SHIFTS, which NSHIFTS is possibly 0.
1530
1531         * src/LR0.c (shifts_new): Be global and move to..
1532         * src/state.c, src/state.h: here.
1533         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1534         * src/print_graph: Adjust.
1535
1536 2001-12-05  Akim Demaille  <akim@epita.fr>
1537
1538         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1539         * src/conflicts.c: Use it.
1540         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1541         incorrectly ``simplified''.
1542
1543 2001-12-05  Akim Demaille  <akim@epita.fr>
1544
1545         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1546         using the good o' techniques: arrays not pointers, variable
1547         locality, BITISSET, RESETBIT etc.
1548
1549 2001-12-05  Akim Demaille  <akim@epita.fr>
1550
1551         * src/state.h (SHIFT_SYMBOL): New.
1552         * src/conflicts.c: Use it to deobfuscate.
1553
1554 2001-12-05  Akim Demaille  <akim@epita.fr>
1555
1556         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1557         (print_reductions): De-obfuscate using the good o' techniques:
1558         arrays not pointers, variable locality, BITISSET.
1559
1560 2001-12-05  Akim Demaille  <akim@epita.fr>
1561
1562         * src/conflicts.c (print_reductions): Arrays, not pointers.
1563         Use BITISSET.
1564
1565 2001-12-05  Akim Demaille  <akim@epita.fr>
1566
1567         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1568
1569 2001-12-05  Akim Demaille  <akim@epita.fr>
1570
1571         * src/conflicts.c (print_reductions): Improve variable locality.
1572
1573 2001-12-05  Akim Demaille  <akim@epita.fr>
1574
1575         * src/conflicts.c (print_reductions): Pessimize, but clarify.
1576
1577 2001-12-05  Akim Demaille  <akim@epita.fr>
1578
1579         * src/conflicts.c (print_reductions): Improve variable locality.
1580
1581 2001-12-05  Akim Demaille  <akim@epita.fr>
1582
1583         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1584         * src/lalr.c: Use them.
1585
1586 2001-12-05  Akim Demaille  <akim@epita.fr>
1587
1588         * src/LR0.c (augment_automaton): Formatting changes.
1589         Better variable locality.
1590
1591 2001-12-05  Akim Demaille  <akim@epita.fr>
1592
1593         * src/lalr.c (matrix_print): New.
1594         (transpose): Use it.
1595         Use arrays instead of pointers.
1596
1597 2001-12-05  Akim Demaille  <akim@epita.fr>
1598
1599         * src/lalr.c (maxrhs): Move to...
1600         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1601         * src/lalr.c (build_relations): Adjust.
1602
1603 2001-12-05  Akim Demaille  <akim@epita.fr>
1604
1605         * src/lalr.c (transpose): Free the memory allocated to the
1606         argument, as it is replaced by the results by the unique caller.
1607         (build_relations): Merely invoke transpose: it handles the memory
1608         deallocation.
1609         Improve variable locality.
1610         Avoid variables used as mere abbreviations.
1611         (compute_lookaheads): Use arrays instead of pointers.
1612
1613 2001-12-05  Akim Demaille  <akim@epita.fr>
1614
1615         * src/lalr.c (initialize_F): Improve variable locality.
1616         Avoid variables used as mere abbreviations.
1617
1618 2001-12-05  Akim Demaille  <akim@epita.fr>
1619
1620         * src/derives.c (print_derives): Display the ruleno.
1621         * src/lalr.c (initialize_F, transpose): Better variable locality
1622         to improve readability.
1623         Avoid variables used as mere abbreviations.
1624
1625 2001-12-05  Akim Demaille  <akim@epita.fr>
1626
1627         * src/lalr.c (traverse): Use arrays instead of pointers.
1628
1629 2001-12-05  Akim Demaille  <akim@epita.fr>
1630
1631         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1632         the handling of squeue.
1633         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1634
1635 2001-12-05  Akim Demaille  <akim@epita.fr>
1636
1637         Because useless nonterminals are now kept alive (instead of being
1638         `destroyed'), we now sometimes examine them, and store information
1639         related to them.  Hence we need to know their number, and adjust
1640         memory allocations.
1641
1642         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1643         static.
1644         * src/LR0.c (allocate_itemsets): The memory allocated to
1645         `symbol_count' was used for two different purpose: once to count
1646         the number of occurrences of each symbol, and later reassigned to
1647         `shift_symbol', containing the symbol that can be shifted from a
1648         given state.
1649         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1650         only, and...
1651         (new_itemsets): Allocate `shift_symbol' here.
1652         (allocate_itemsets): symbol_count includes useless nonterminals.
1653         Make room for them.
1654         (free_storage): Use `free', not `XFREE', for pointers that cannot
1655         be null.
1656
1657 2001-12-05  Akim Demaille  <akim@epita.fr>
1658
1659         * src/nullable.c (set_nullable): Deobfuscate the handling of
1660         ritem.
1661         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1662
1663 2001-12-05  Akim Demaille  <akim@epita.fr>
1664
1665         * src/gram.c, src/gram.h (ritem_print): New.
1666         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1667         (This useless function was defined only to work around VMS linkers
1668         that can't handle compilation units with variables only).
1669         * src/reduce.c (dump_grammar): Use it to trace the construction of
1670         ritem.
1671
1672 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1673
1674         * src/bison.simple (union yyalloc): Change member names
1675         to be the same as the stack names.
1676         (yyparse): yyptr is now union yyalloc *, not char *.
1677         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1678         and may generate better code on some machines.
1679         (yystpcpy): Use prototype if __STDC__ is defined, not just
1680         if __cplusplus is defined.
1681
1682 2001-11-30  Akim Demaille  <akim@epita.fr>
1683
1684         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1685         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1686         Gettext doesn't compile cleanly, and dies with -Werror.
1687         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1688         Include WARNING_CFLAGS here.
1689         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1690         before being defined.
1691
1692 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1693
1694         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1695         First arg is int, not unsigned.
1696         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1697         (SIZE_MAX, UINT_MAX): New macros.
1698         (quotearg_n_options): Abort if N is negative.
1699         Avoid overflow check on hosts where size_t is 64 bits and int
1700         is 32 bits, as overflow is impossible there.
1701         Fix off-by-one typo that caused unnecessary reallocation.
1702
1703 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1704
1705         Name space cleanup in generated parser.
1706
1707         * doc/bison.texinfo (Bison Parser): Discuss system headers
1708         and their effect on the user name space.
1709
1710         * src/bison.simple:
1711         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1712         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1713         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1714
1715         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1716         on user names when possible.
1717
1718         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1719         Simplify test for whather <alloca.h> exists.
1720
1721         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1722
1723         (<stdio.h>): Include if YYDEBUG.
1724
1725         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1726         ! defined (yyoverflow) && ! defined (yymemcpy).
1727
1728         (yymemcpy, yyparse): Rename local variables as needed so that
1729         they all begin with 'yy'.
1730
1731         (yystrlen, yystpcpy): New functions.
1732
1733         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1734         All uses changed.
1735
1736         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1737         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1738         and YYSTACK_FREE instead of malloc and free.
1739
1740 2001-11-30  Akim Demaille  <akim@epita.fr>
1741
1742         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
1743         before their first uses.
1744         (YYBISON, YYPURE): Move to the top of the output.
1745
1746 2001-11-30  Akim Demaille  <akim@epita.fr>
1747
1748         * tests/reduce.at (Useless Nonterminals): Fix.
1749
1750 2001-11-30  Akim Demaille  <akim@epita.fr>
1751
1752         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1753         if body instead of `;' to pacify GCC's warnings.
1754
1755 2001-11-30  Akim Demaille  <akim@epita.fr>
1756
1757         Instead of mapping the LHS of unused rules to -1, keep the LHS
1758         valid, but flag the rules as invalid.
1759
1760         * src/gram.h (rule_t): `useful' is a new member.
1761         * src/print.c (print_grammar): Adjust.
1762         * src/derives.c (set_derives): Likewise.
1763         * src/reader.c (packgram, reduce_output): Likewise.
1764         * src/reduce.c (reduce_grammar_tables): Likewise.
1765         * tests/reduce.at (Underivable Rules, Useless Rules): New.
1766
1767 2001-11-30  Akim Demaille  <akim@epita.fr>
1768
1769         * src/reduce.c (reduce_output): Formatting changes.
1770         * src/print.c (print_results, print_grammar): Likewise.
1771         * tests/regression.at (Rule Line Numbers)
1772         (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
1773
1774 2001-11-30  Akim Demaille  <akim@epita.fr>
1775
1776         * src/reduce.c (nonterminals_reduce): Instead of throwing away
1777         useless nonterminals, move them at the end of the symbol arrays.
1778         (reduce_output): Adjust.
1779         * tests/reduce.at (Useless Nonterminals): Adjust.
1780
1781 2001-11-30  Akim Demaille  <akim@epita.fr>
1782
1783         * src/reduce.c: Various comment/formatting changes.
1784         (nonterminals_reduce): New, extracted from...
1785         (reduce_grammar_tables): here.
1786         (reduce_grammar): Call nonterminals_reduce.
1787
1788 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1789
1790         * src/bison.simple (YYSTACK_REALLOC): Remove.
1791         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1792         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1793         New macros.
1794         (union yyalloc): New type.
1795         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1796         an arbitrary restriction on hosts where size_t is wider than int.
1797
1798         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1799         a parser stack overflow.  Allocate just one block of memory for all
1800         three stacks, instead of allocating three blocks; this typically is
1801         faster and reduces fragmentation.
1802
1803         Do not limit the number of items in the stack to a value that fits
1804         in 'int', as this is an arbitrary limit on hosts with 64-bit
1805         size_t and 32-bit int.
1806
1807 2001-11-29  Marc Autret  <autret_m@epita.fr>
1808
1809         * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead
1810         of defining YYERROR_VERBOSE.
1811         [AT_DATA]: $4 is now out of C declarations in the prologue.
1812
1813 2001-11-28  Marc Autret  <autret_m@epita.fr>

2232         * tests/calc.at, tests/output.at, tests/regression.at,
2233         * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
2234         now the tests are run in private dirs, therefore AC_CLEANUP and

2236         * tests/atlocal.in: Now that we run `elsewhere' than in tests/,

2257         * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
2258         Revert a previous patch:  these are really const.

2262         arg_offset.

2361         * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do
2362         with yyltype/YYLTYPE.  This allows inclusion of the generated

3595         * m4/error.m4: Run AC_FUNC_STRERROR_R.

3597
3598 2001-03-16  Akim Demaille  <akim@epita.fr>
3599
3600         * src/getargs.c (longopts): Clean up.
3601
3602 2001-02-21  Akim Demaille  <akim@epita.fr>
3603
3604         * src/reader.c (gensym): `gensym_count' is your own.
3605         Use a static buf to create the symbol name, as token_buffer is no
3606         longer a buffer.
3607
3608 2001-02-08  Akim Demaille  <akim@epita.fr>
3609
3610         * src/conflicts.c (conflict_report): Be sure not to append to res
3611         between two calls, which could happen if both first sprintf were
3612         skipped, but not the first cp += strlen.
3613
3614 2001-02-08  Akim Demaille  <akim@epita.fr>
3615
3616         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
3617         New, from fileutils 4.0.37.
3618         * configure.in: Require Autoconf 2.49c.  I took some time before
3619         making this decision.  This is the only way out for portability
3620         issues in Bison, it would mean way too much duplicate effort to
3621         import in Bison features implemented in 2.49c since 2.13.
3622         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
3623
3624 2001-02-02  Akim Demaille  <akim@epita.fr>
3625
3626         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

3628
3629 2001-01-19  Akim Demaille  <akim@epita.fr>
3630
3631         Get rid of the ad hoc handling of token_buffer in the scanner: use
3632         the obstacks.
3633
3634         * src/lex.c (token_obstack): New.
3635         (init_lex): Initialize it.  No longer call...
3636         (grow_token_buffer): this.  Remove it.
3637         Adjust all the places which used it to use the obstack.
3638
3639 2001-01-19  Akim Demaille  <akim@epita.fr>
3640
3641         * src/lex.h: Rename all the tokens:
3642         s/\bENDFILE\b/tok_eof/g;
3643         s/\bIDENTIFIER\b/tok_identifier/g;
3644         etc.
3645         Let them be enums, not #define, to ease debugging.
3646         Adjust all the code.
3647
3648 2001-01-18  Akim Demaille  <akim@epita.fr>
3649
3650         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
3651         * src/lex.c (maxtoken, grow_token_buffer): Static.
3652
3653 2001-01-18  Akim Demaille  <akim@epita.fr>
3654
3655         Since we now use obstacks, more % directives can be enabled.
3656
3657         * src/lex.c (percent_table): Also accept `%yacc',
3658         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3659         `%debug'.
3660         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3661         instead of returning a token.
3662         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3663         * src/reader.c (read_declarations): Adjust.
3664         * src/files.c (open_files): Don't call `compute_base_names', don't
3665         compute `attrsfile' since they depend upon data which might be
3666         *in* the input file now.
3667         (output_files): Do it here.
3668         * src/output.c (output_headers): Document the fact that this patch
3669         introduces a guaranteed SEGV for semantic parsers.
3670         * doc/bison.texinfo: Document them.
3671         * tests/suite.at: Exercise these %options.
3672
3673 2000-12-20  Akim Demaille  <akim@epita.fr>
3674
3675         Also handle the output file (--verbose) with obstacks.
3676
3677         * files.c (foutput): Remove.
3678         (output_obstack): New.
3679         Adjust all dependencies.
3680         * src/conflicts.c: Return a string.
3681         * src/system.h (obstack_grow_string): Rename as...
3682         (obstack_sgrow): this.  Be ready to work with non literals.
3683         (obstack_fgrow4): New.
3684
3685 2000-12-20  Akim Demaille  <akim@epita.fr>
3686
3687         * src/files.c (open_files): Fix the computation of short_base_name
3688         in the case of `-o foo.tab.c'.
3689
3690 2000-12-20  Akim Demaille  <akim@epita.fr>
3691
3692         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3693         (copy_dollar): Now that everything uses obstacks, get rid of the
3694         FILE * parameters.
3695
3696 2000-12-20  Akim Demaille  <akim@epita.fr>
3697
3698         * src/files.c (open_files): Actually the `.output' file is based
3699         on the short_base_name, not base_name.
3700         * tests/suite.at (Checking output file names): Adjust.
3701
3702 2000-12-20  Akim Demaille  <akim@epita.fr>
3703
3704         * src/bison.s1: Remove, we now use directly...
3705         * src/bison.simple: this.
3706         * src/Makefile.am: Use pkgdata instead of data.
3707
3708 2000-12-20  Akim Demaille  <akim@epita.fr>

3719         vars.
3720         (open_files): Don't compute them.
3721         (output_files): Adjust.
3722         (base_name, short_base_name): Be global.
3723         Adjust dependencies.
3724
3725 2000-12-19  Akim Demaille  <akim@epita.fr>
3726
3727         * src/files.c (strsuffix): New.
3728         (stringappend): Be just like strcat but allocate.
3729         (base_names): Eve out from open_files.
3730         Try to simplify the rather hairy computation of base_name and
3731         short_base_name.
3732         (open_files): Use it.
3733         * tests/suite.at (Checking output file names): New test.
3734
3735 2000-12-19  Akim Demaille  <akim@epita.fr>

3739         * src/output.c (output_parser): Recognize `%% actions' instead of
3740         `$'.
3741         * src/bison.s1: s/$/%% actions/.
3742         * src/bison.hairy: Likewise.
3743
3744 2000-12-19  Akim Demaille  <akim@epita.fr>
3745
3746         * src/output.c (output_parser): Compute the `#line' lines when
3747         there are.
3748         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3749         Suggested by Hans Aberg.
3750
3751 2000-12-19  Akim Demaille  <akim@epita.fr>
3752
3753         Let the handling of the skeleton files be local to the procedures
3754         that use it.
3755
3756         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
3757         longer static.
3758         (fparser, open_extra_files): Remove.
3759         (open_files, output_files): Don't take care of fparser.

3765
3766 2000-12-19  Akim Demaille  <akim@epita.fr>
3767

3769         * src/system.h (BISON_SIMPLE, BISON_HAIRY): ... to here.
3770
3771 2000-12-19  Akim Demaille  <akim@epita.fr>
3772
3773         * src/files.c (open_files): Yipee!  We no longer need all the code
3774         looking for `/tmp' since we have no tmp file.
3775
3776 2000-12-19  Akim Demaille  <akim@epita.fr>
3777
3778         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
3779         New macros.
3780         * src/files.c (open_files): Less dependency on MSDOS etc.

3804
3805         * lib/obstack.h: Formatting changes.
3806         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3807         prevents type checking.
3808         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3809         cast the value to (void *): assigning a `foo *' to a `void *'
3810         variable is valid.
3811         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3812         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3828
3829         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

3847
3848 2000-11-07  Akim Demaille  <akim@epita.fr>
3849
3850         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3851         Merge in a single CPP if/else.
3852
3853 2000-11-07  Akim Demaille  <akim@epita.fr>
3854
3855         * src/output.c (output): Remove useless variables.
3856         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3857         argument `data' for consistency with the prototypes.
3858         Qualify it `const'.
3859         (obstack_copy, obstack_copy0): Rename the second argument as
3860         `address' for consistency.  Qualify it `const'.
3861         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
3862         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
3863         `const' their input argument (`data' or `address').
3864         Adjust the corresponding macros to include `const' in casts.

3866 2000-11-03  Akim Demaille  <akim@epita.fr>
3867

3870         Adjust dependencies.
3871
3872 2000-11-03  Akim Demaille  <akim@epita.fr>
3873
3874         For some reason, this was not applied.
3875
3876         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

3880

3891         Use `obstack_save'.
3892         * src/main.c (main): Don't use `atexit' to register `done', since
3893         it no longer has to remove tmp files, just call `output_files'
3894         when there are no errors.
3895
3896 2000-11-02  Akim Demaille  <akim@epita.fr>

3966         the `/' which is suspected to open a comment, instead of being
3967         called after `//' or `/*' was read.
3968         (copy_comment, copy_definition, parse_union_decl, copy_action)
3969         (copy_guard): Adjust.

3999         When a literal string is used to define two different tokens,
4000         `bison -v' segfaults.
4001         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

4009

4013
4014 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4015
4016         * bison.s1 (yyparse): Assign the default value
4017         unconditionally, to avoid a GCC warning and make the parser a
4018         tad smaller.
4019
4020 2000-10-02  Akim Demaille  <akim@epita.fr>
4021

4026
4027         * src/derives.c, src/print.c, src/reduce.c: To ease the
4028         translation, move some `\n' out of the translated strings.
4029
4030 2000-10-02  Akim Demaille  <akim@epita.fr>
4031
4032         The location tracking mechanism is precious for parse error
4033         messages.  Nevertheless, it is enabled only when `@n' is used in
4034         the grammar, which is a different issue (you can use it in error
4035         message, but not in the grammar per se).  Therefore, there should
4036         be another means to enable it.
4037
4038         * src/getargs.c (getargs): Support `--locations'.
4039         (usage): Report it.
4040         * src/getargs.h (locationsflag): Export it.
4041         * src/lex.c (percent_table): Support `%locations'.
4042         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4043         with `locationsflag'.
4044         * doc/bison.texinfo: Document `--locations' and `%locations'.
4045         Sort the options.
4046         * tests/calc.m4: Test it.
4047
4048         For regularity of the names, replace each
4049         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4050         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4051         In addition replace each `flag' with `_flag'.
4052
4053 2000-10-02  Akim Demaille  <akim@epita.fr>
4054
4055         Also test parse error messages, including with YYERROR_VERBOSE.
4056
4057         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4058         associative).
4059         Use it to check the computations.
4060         Use it to check `nonassoc' is honored.
4061         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4062         `--yyerror-verbose'.
4063         (_AT_CHECK_CALC): Adjust to this option.
4064         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4065
4066 2000-10-02  Akim Demaille  <akim@epita.fr>
4067
4068         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4069         the latter demonstrates a flaw in the handling of non debugging
4070         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4071         was used in order to simplify:
4072
4073         #if YYDEBUG
4074         if (yydebug)
4075         {
4076         ...
4077         }
4078         #endif
4079
4080         into
4081
4082         if (yydebug)
4083         {
4084         ...
4085         }
4086
4087         unfortunately this leads to a CPP conflict when
4088         `--name-prefix=foo' is used since it produces `#define yydebug
4089         foodebug'.
4090
4091         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4092         (YYDPRINTF): New macro.
4093         Spread its use.
4094         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4095         the bison options.
4096         Also test `--verbose', `--defines' and `--name-prefix'.
4097
4098 2000-10-02  Akim Demaille  <akim@epita.fr>
4099
4100         Improve the readability of the produced parsers.
4101
4102         * src/bison.s1: Formatting changes.
4103         Improve the comment related to the `$' mark.
4104         (yydefault): Don't fall through to `yyresume': `goto' there.
4105         * src/output.c (output_parser): When the `$' is met, skip the end
4106         of its line.
4107         New variable, `number_of_dollar_signs', to check there's exactly
4108         one `$' in the parser skeleton.
4109
4110 2000-10-02  Akim Demaille  <akim@epita.fr>
4111
4112         * lib/xstrdup.c: New file, from the fileutils.
4113         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4114         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4115         instead of strlen + xmalloc + strcpy.
4116         * src/symtab.c (copys): Remove, use xstrdup instead.
4117
4118 2000-10-02  Akim Demaille  <akim@epita.fr>
4119
4120         * src/gram.h (associativity): New enum type which replaces the
4121         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4122         `right_assoc', `left_assoc' and `non_assoc'.
4123         Adjust all dependencies.
4124         * src/reader.c: Formatting changes.
4125         (LTYPESTR): Don't define it, use it as a literal in
4126         `reader_output_yylsp'.
4127         * src/symtab.h (symbol_class): New enum type which replaces the
4128         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4129         `sunknown', `stoken and `snterm'.
4130
4131 2000-10-02  Akim Demaille  <akim@epita.fr>
4132
4133         * src/getargs.c (fixed_outfiles): Rename as...

4135         Adjust dependencies.
4136
4137 2000-10-02  Akim Demaille  <akim@epita.fr>
4138
4139         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4140         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4141         difficult and introduced a lot of core dump.  It turns out that
4142         Bison used an implementation of `xmalloc' based on `calloc', and
4143         at various places it does depend upon the initialization to 0.  I
4144         have not tried to isolate the pertinent places, and all the former
4145         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4146         someone should address this issue.
4147
4148         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4149         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

4242
4243         * src/output.c (token_actions): Introduce a temporary array,

4245         output_short_table.
4246
4247 2000-10-02  Akim Demaille  <akim@epita.fr>
4248
4249         `user_toknums' is output as a `short[]' in `output.c', while it is
4250         defined as a `int[]' in `reader.c'.  For consistency with the
4251         other output tables, `user_toknums' is now defined as a table of
4252         shorts.
4253
4254         * src/reader.c (user_toknums): Be a short table instead of an int

4267         order to get rid of the `static' prototypes.
4268         No longer use `register'.
4269         * src/output.h: New file.

4294         Don't define PARAMS.
4295         * src/system.h: Define PARAMS.
4296         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
4297         purpose of config.h.  system.h must not try to fix wrong

4460         the file name, not the whole `#line LINE FILE'.
4461
4462 2000-03-17  Akim Demaille  <akim@epita.fr>
4463
4464         On syntax errors, report the token on which we choked.
4465
4466         * src/bison.s1 (yyparse): In the label yyerrlab, when

4484
4485         * src/reader.c (copy_definition): Use copy_string and
4486         copy_comment.  Removed now unused `match', `ended',
4487         `cplus_comment'.
4488         (copy_comment, copy_string): Moved, to be visible from
4489         copy_definition.
4490

4492
4493         * src/reader.c (copy_string): Declare `static inline'.  No

4515
4516         Change the handling of @s so that they behave exactly like $s.
4517         There is now a pseudo variable @$ (readble and writable), location
4518         of the lhs of the rule (by default ranging from the location of
4519         the first symbol of the rhs, to the location of the last symbol,
4520         or, if the rhs is empty, YYLLOC).
4521
4522         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4523         yyval.
4524         (yyparse): When providing a default semantic action, provide a
4525         default location action.
4526         (after the $): No longer change `*YYLSP', just stack YYLOC the
4527         same way you stack YYVAL.
4528         * src/reader.c (read_declarations): Use warns.
4529         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4530         (copy_action, case '@'): Likewise.
4531         Use a standard error message, to save useless work from
4532         translators.
4533
4534 2000-03-17  Akim Demaille  <akim@epita.fr>
4535
4536         * src/bison.s1: Formatting and cosmetics changes.

4553
4554         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4555         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4556         One `#if YYDEBUG' remains, since it uses variables which are
4557         defined only if `YYDEBUG != 0'.
4558
4559 2000-03-16  Akim Demaille  <akim@epita.fr>

4583         handled via src/Makefile.am.

4585         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
4586         autoheader.

4591         the proper line number and file name.
4592         (DEFS): Propagate the location of bison library files and of the
4593         locale files.
4594         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4595         builddir.
4596         * acinclude.m4: Remove, replaced by the directory m4.
4597         * m4/Makefile.am (EXTRA_DIST): New variable.
4598         * m4/gettext.m4: New file, from the fileutils.

5285         major changes to files.c.
