 100 2002-02-14  Paul Eggert  <eggert@twinsun.com>
 101
 102         Remove the support for C++ namespace cleanliness; it was
 103         causing more problems than it was curing, since it didn't work
 104         properly on some nonstandard C++ compilers.  This can wait
 105         for a proper C++ parser.
 106
 107         * NEWS: Document this.
 108         * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
 109         of C++, as it's treated like C now.

 111         (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):

 113         namespace cleanliness.

 116

 123 2002-02-13  Andreas Schwab  <schwab@suse.de>
 124
 125         * src/output.c (output_rule_data): Don't output NULL, it might
 126         not be defined yet.
 127

 146
 147 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 148
 149         * data/bison.c++: Replace some direct m4 expansions by constants.  Be
 150         more consistent when naming methods and variables.  Put preprocessor
 151         directives around tables only needed for debugging.
 152
 153 2002-02-07  Robert Anisko  <robert@lrde.epita.fr>
 154
 155         * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in

 173 2002-02-06  Robert Anisko  <robert@lrde.epita.fr>
 174
 175         * data/bison.c++: Adjust the parser code.  Fix some muscles that were
 176         not expanded by m4.
 177
 178 2002-02-05  Akim Demaille  <akim@epita.fr>
 179
 180         * data/bison.c++: Adjust to the M4 back end.
 181         More is certainly needed.

 190         * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
 191         specific values.  Now it is m4 that performs the lookup.
 192         * src/parse-skel.y: Remove.
 193         * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
 194         * src/output.c (actions_output, guards_output)
 195         (token_definitions_output): No longer keeps track of the output
 196         line number, hence remove the second argument.
 197         (guards_output): Check against the guard member of a rule, not the
 198         action member.
 199         Adjust callers.
 200         (output_skeleton): Don't look for the skeleton location, let m4 do
 201         that.
 202         Create `/tmp/muscles.m4'.  This is temporary, a proper temporary
 203         file will be used.
 204         Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
 205         (prepare): Given that for the time being changesyntax is not
 206         usable in M4, rename the muscles using `-' to `_'.
 207         Define `defines_flag', `output_parser_name' and `output_header_name'.
 208         * src/output.h (actions_output, guards_output)
 209         (token_definitions_output): Adjust prototypes.
 210         * src/scan-skel.l: Instead of scanning the skeletons, it now
 211         processes the output of m4: `__oline__' and `#output'.
 212         * data/bison.simple: Adjust to be used by M4(sugar).
 213         * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
 214         to date.
 215         * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
 216         instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
 217         * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
 218         shamelessly stolen from CVS Autoconf.

 232

 234         * data/: here.
 235
 236 2002-01-29  Paul Eggert  <eggert@twinsun.com>
 237
 238         * src/bison.simple (YYSIZE_T): Do not define merely because
 239         YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
 240         On some platforms, <alloca.h> does not declare YYSTD (size_t).
 241
 242 2002-01-27  Akim Demaille  <akim@epita.fr>
 243
 244         Fix `%nonassoc and eof'.
 245
 246         * src/state.c (errs_dup): Aaaah!  The failure was due to bytes
 247         which were not properly copied!  Replace
 248         memcpy (res->errs, src->errs, src->nerrs);
 249         with
 250         memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
 251         !!!
 252         * tests/regression.at (%nonassoc and eof): Adjust to newest
 253         Autotest: `.' is not in the PATH.

 256
 257         * tests/sets.at (AT_EXTRACT_SETS): New.

 263         * tests/actions.at, tests/calc.at, tests/headers.at,
 264         * tests/torture.at: Adjust to the newest Autotest which no longer
 265         forces `.' in the PATH.

 315         canonical definition.
 316         * src/system.h: Use the canonical definition for PARAMS (avoids

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

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

1003 2001-12-22  Akim Demaille  <akim@epita.fr>

1006         Reported by Mike Castle.
1007
1008         * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
1009         * tests/regression.at (Web2c): Rename as...
1010         (Web2c Report): this.
1011         (Web2c Actions): New.
1012
1013 2001-12-22  Akim Demaille  <akim@epita.fr>
1014
1015         Reductions in web2c.y are improperly reported.
1016         Reported by Mike Castle.
1017
1018         * src/conflicts.c (print_reductions): Fix.
1019         * tests/regression.at (Web2c): New.
1020
1021 2001-12-18  Akim Demaille  <akim@epita.fr>
1022
1023         Some host fail on `assert (!"foo")', which expands to
1024         ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
1025         Reported by Nelson Beebee.
1026
1027         * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
1028         `#define it_succeeded 0' and `assert (it_succeeded)'.
1029
1030 2001-12-17  Marc Autret  <autret_m@epita.fr>
1031
1032         * src/bison.simple: Don't hard code the skeleton line and filename.
1033         * src/output.c (output_parser): Rename 'line' as 'output_line'.
1034         New line counter 'skeleton_line' (skeleton-line muscle).
1035
1036 2001-12-17  Paul Eggert  <eggert@twinsun.com>
1037
1038         * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
1039         YYDEBUG must be defined to a nonzero value.
1040
1041         * src/bison.simple (yytname): Do not assume that the user defines
1042         YYDEBUG to a properly parenthesized expression.
1043
1044 2001-12-17  Akim Demaille  <akim@epita.fr>
1045
1046         * src/state.h (state_t): Rename lookaheads as lookaheadsp.
1047         nlookaheads is a new member.
1048         Adjust all users.
1049         * src/lalr.h (nlookaheads): Remove this orphan declaration.
1050         * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
1051         state.
1052
1053 2001-12-17  Akim Demaille  <akim@epita.fr>
1054
1055         * src/files.h, src/files.c (open_files, close_files): Remove.
1056         * src/main.c (main): Don't open/close files, nor invoke lex_free,
1057         let...
1058         * src/reader.c (reader): Do it.
1059
1060 2001-12-17  Akim Demaille  <akim@epita.fr>
1061
1062         * src/conflicts.c (print_reductions): Formatting changes.
1063

1071
1072         * src/output.c (output_obstack): Be static and rename as...

1074         output_obstack.
1075         * src/reader.h (muscle_obstack): Move to...
1076         * src/output.h: here, since it's defined in output.c.
1077
1078 2001-12-17  Akim Demaille  <akim@epita.fr>

1082         locality.
1083
1084 2001-12-17  Akim Demaille  <akim@epita.fr>

1097
1098         * src/output.c (actions_output): Fix. When we use %no-lines,
1099         there is one less line per action.
1100
1101 2001-12-16  Marc Autret  <autret_m@epita.fr>
1102
1103         * src/bison.simple: Remove a useless #line directive.
1104         s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
1105         * src/output.c (get_lines_number): New.
1106         (output_parser): Adjust, now takes care about the lines of a
1107         output muscles.
1108         Fix line numbering.
1109         (actions_output): Computes the number of lines taken by actions.
1110         (output_master_parser): Insert new skeleton which is the name of
1111         the output parser file name.

1113 2001-12-15  Marc Autret  <autret_m@epita.fr>
1114
1115         * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
1116
1117 2001-12-15  Marc Autret  <autret_m@epita.fr>
1118
1119         * src/output.c (output_gram): Keep track of the hairy one.
1120
1121 2001-12-15  Akim Demaille  <akim@epita.fr>
1122
1123         Make `make distcheck' work.
1124
1125         * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
1126         system.h which uses libgettext.h.
1127
1128 2001-12-15  Akim Demaille  <akim@epita.fr>
1129
1130         * src/nullable.c (set_nullable): Useless rules must be skipped,
1131         otherwise, since we range over their symbols, we might look at a
1132         nonterminal which no longer ``exists'', i.e., it is not counted in
1133         `nvars', hence we overflow our arrays.
1134
1135 2001-12-15  Akim Demaille  <akim@epita.fr>
1136
1137         The header can also be produced directly, without any obstack!
1138         Yahoo!
1139
1140         * src/files.c, src/files.h (defines_obstack): Remove.
1141         (compute_header_macro): Global.
1142         (defines_obstack_save): Remove.
1143         * src/reader.c (parse_union_decl): No longer output to
1144         defines_obstack: its content can be found in the `stype' muscle
1145         anyway.
1146         (output_token_translations): Merge into...
1147         (symbols_output): this.
1148         Rename as...
1149         (symbols_save): this.
1150         (reader): Adjust.
1151         * src/output.c (header_output): New.
1152         (output): Call it.
1153
1154 2001-12-15  Akim Demaille  <akim@epita.fr>
1155
1156         * src/reader.c (parse_union_decl): Instead of handling two obstack
1157         simultaneously, use one to define the `stype' muscle, and use the
1158         value of the latter to fill defines_obstack.
1159         (copy_comment): Remove.
1160         (copy_comment2): Work for a single obstack.
1161         Rename as...
1162         (copy_comment): this.
1163
1164 2001-12-15  Akim Demaille  <akim@epita.fr>
1165
1166         * src/lex.c, src/lex.h (xgetc): No longer static.
1167         * src/reader.c (parse_union_decl): Revamp.
1168
1169 2001-12-15  Akim Demaille  <akim@epita.fr>
1170
1171         Still making progress in separating Bison into (i) input, (ii)
1172         process, (iii) output: now we can directly output the parser file
1173         without using table_obstack at all.
1174
1175         * src/files.c, src/files.h (table_obstack): Bye bye.
1176         (parser_file_name): New.
1177         * src/files.c (compute_output_file_names): Compute it.
1178         * src/output.c (actions_output, output_parser)
1179         (output_master_parser): To a file instead of an obstack.
1180
1181 2001-12-15  Akim Demaille  <akim@epita.fr>
1182
1183         Attach actions to rules, instead of pre-outputting them to
1184         actions_obstack.
1185
1186         * src/gram.h (rule_t): action and action_line are new members.
1187         * src/reader.c (symbol_list): Likewise.
1188         (copy_action): Save the actions within the rule.
1189         (packgram): Save them in rule_table.
1190         * src/output.c (actions_output): New.
1191         (output_parser): Use it on `%%actions'.
1192         (output_rule_data): Don't free rule_table.
1193         (output): Do it.
1194         (prepare): Don't save the `action' muscle.
1195         * src/bison.simple: s/%%action/%%actions/.
1196
1197 2001-12-15  Akim Demaille  <akim@epita.fr>
1198
1199         * src/reader.c (copy_action): When --yacc, don't append a `;'
1200         to the user action: let it fail if lacking.
1201         Suggested by Arnold Robbins and Tom Tromey.
1202
1203 2001-12-14  Akim Demaille  <akim@epita.fr>
1204
1205         * src/lex.c (literalchar): Simply return the char you decoded, non
1206         longer mess around with obstacks and int pointers.
1207         Adjust all callers.
1208
1209 2001-12-14  Akim Demaille  <akim@epita.fr>
1210
1211         * src/lex.c (literalchar): Don't escape the special characters,
1212         just decode them, and keep them as char (before, eol was output as
1213         the 2 char string `\n' etc.).
1214         * src/output.c (output_rule_data): Use quotearg to output the
1215         token strings.
1216
1217 2001-12-13  Paul Eggert  <eggert@twinsun.com>
1218
1219         * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
1220         Do not infringe on the global user namespace when using C++.
1221         (YYFPRINTF, YYSTDERR): New macros, needed for the above.
1222         All uses of `fprintf' and `stderr' changed.
1223
1224         * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
1225
1226 2001-12-13  Akim Demaille  <akim@epita.fr>
1227
1228         The computation of nullable is broken: it doesn't handle empty
1229         RHS's properly.
1230
1231         * tests/torture.at (GNU AWK Grammar): New.
1232         * tests/sets.at (Nullable): New.
1233         * src/nullable.c (set_nullable): Instead of blindly looping over
1234         `ritems', loop over the rules, and then over their rhs's.
1235
1236         Work around Autotest bugs.
1237
1238         * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
1239         frame, because Autotest understand lines starting with a `+' as
1240         traces from the shell.  Then, they are not processed properly.
1241         Admittedly an Autotest bug, but we don't have time to wait for
1242         Autotest to catch up.
1243         * tests/regression.at (Broken Closure): Adjust to the new table
1244         frames.
1245         Move to...
1246         * tests/sets.at: here.
1247
1248 2001-12-13  Akim Demaille  <akim@epita.fr>
1249
1250         * src/closure.c (closure): Use nrules instead of playing tricks
1251         with BITS_PER_WORD.
1252
1253 2001-12-13  Akim Demaille  <akim@epita.fr>
1254
1255         * src/print.c (print_actions): Output the handling of `$' as the
1256         traces do: shifting the token EOF.  Before EOF was treated as a
1257         nonterminal.
1258         * tests/regression.at: Adjust some tests.
1259         * src/print_graph.c (print_core): Complete the set of items via
1260         closure.  The next-to-final and final states are still unsatisfying,
1261         but that's to be addressed elsewhere.
1262         No longer output the rule numbers, but do output the state number.
1263         A single loop for the shifts + gotos is enough, but picked a
1264         distinct color for each.
1265         (print_graph): Initialize and finalize closure.
1266
1267 2001-12-13  Akim Demaille  <akim@epita.fr>
1268
1269         * src/reader.c (readgram): Remove dead code, an strip useless
1270         braces.
1271         (get_type): Remove, unused.
1272
1273 2001-12-12  Akim Demaille  <akim@epita.fr>
1274
1275         * src/complain.h, src/complain.c: Remove error_one_per_line, rely
1276         on that of lib/error.c.
1277
1278 2001-12-12  Akim Demaille  <akim@epita.fr>
1279
1280         Some hosts don't like `/' in includes.
1281
1282         * src/system.h: Include libgettext.h without qualifying the path.
1283         * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
1284         $(top_srcdir).
1285
1286 2001-12-11  Marc Autret  <autret_m@epita.fr>
1287
1288         * src/output.c (output_parser): Remove useless muscle.
1289
1290 2001-12-11  Marc Autret  <autret_m@epita.fr>
1291
1292         * src/bison.simple: Remove #line just before %%epilogue. It
1293         is now handled in ...
1294         * src/reader.c (read_additionnal_code): Add the output of a
1295         #line for the epilogue.
1296
1297 2001-12-10  Marc Autret  <autret_m@epita.fr>
1298
1299         * src/reader.c (copy_definition): Re-use CPP-outed code which
1300         replace precedent remove.
1301         * src/bison.simple: Remove #line before %%prologue because
1302         %%input-line is wrong at this time.
1303
1304 2001-12-10  Marc Autret  <autret_m@epita.fr>
1305
1306         * src/reader.c (symbols_output): Clean up.
1307         * src/output.c (output_gram, output): Clean up.
1308
1309 2001-12-10  Akim Demaille  <akim@epita.fr>
1310
1311         * src/lalr.c (initialize_lookaheads): New.  Extracted from...
1312         * src/LR0.c (set_state_table): here.
1313         * src/lalr.c (lalr): Call it.
1314
1315 2001-12-10  Akim Demaille  <akim@epita.fr>
1316
1317         * src/state.h (shifts): Remove the `number' member: shifts are
1318         attached to state, hence no longer need to be labelled with a
1319         state number.
1320
1321 2001-12-10  Akim Demaille  <akim@epita.fr>
1322
1323         Now that states have a complete set of members, the linked list of
1324         shifts is useless: just fill directly the state's shifts member.
1325
1326         * src/state.h (shifts): Remove the `next' member.
1327         * src/LR0.c (first_state, last_state): Remove.
1328         Adjust the callers.
1329         (augment_automaton): Don't look for the shifts that must be added
1330         a shift on EOF: it is those of the state we looked for!  But now,
1331         since shifts are attached, it is no longer needed to looking
1332         merely by its id: its number.
1333
1334 2001-12-10  Akim Demaille  <akim@epita.fr>
1335
1336         * src/LR0.c (augment_automaton): Better variable locality.
1337         Remove an impossible branch: if there is a state corresponding to
1338         the start symbol being shifted, then there is shift for the start
1339         symbol from the initial state.
1340
1341 2001-12-10  Akim Demaille  <akim@epita.fr>
1342
1343         * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
1344         only when appropriate: when insert_start_shifting_state' is not
1345         invoked.
1346         * tests/regression.at (Rule Line Numbers): Adjust.
1347
1348 2001-12-10  Akim Demaille  <akim@epita.fr>
1349
1350         * src/LR0.c (augment_automaton): Now that all states have shifts,
1351         merge the two cases addition shifts to the initial state.
1352
1353 2001-12-10  Akim Demaille  <akim@epita.fr>
1354
1355         * src/lalr.c (set_state_table): Move to...
1356         * src/LR0.c: here.
1357         * src/lalr.c (lalr): Don't call it...
1358         * src/LR0.c (generate_states): do it.
1359         * src/LR0.h (first_state): Remove, only the table is used.
1360
1361 2001-12-10  Akim Demaille  <akim@epita.fr>
1362
1363         * src/LR0.h (first_shift, first_reduction): Remove.
1364         * src/lalr.c: Don't use first_shift: find shifts through the
1365         states.
1366
1367 2001-12-10  Akim Demaille  <akim@epita.fr>
1368
1369         * src/LR0.c: Attach shifts to states as soon as they are
1370         computed.
1371         * src/lalr.c (set_state_table): Instead of assigning shifts to
1372         state, just assert that the mapping was properly done.
1373
1374 2001-12-10  Akim Demaille  <akim@epita.fr>
1375
1376         * src/LR0.c (insert_start_shift): Rename as...
1377         (insert_start_shifting_state): this.
1378         (insert_eof_shifting_state, insert_accepting_state): New.
1379         (augment_automaton): Adjust.
1380         Better locality of the variables.
1381         When looking if the start_symbol is shifted from the initial
1382         state, using `while (... symbol != start_symbol ...)' sounds
1383         better than `while (... symbol < start_symbol ...)': If fail
1384         to see how the order between symbols could be relevant!
1385
1386 2001-12-10  Akim Demaille  <akim@epita.fr>
1387
1388         * src/getargs.h: Don't declare `spec_name_prefix' and
1389         `spec_file_prefix', declared by src/files.h.
1390         * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
1391         * src/muscle_tab.c (muscle_init): Default prefix to NULL.
1392         * src/output.c (prepare): Adjust.
1393         * src/reader.c (symbols_output): Likewise.
1394         * src/vmsgetargs.c: Vaguely adjust, but who cares?
1395
1396 2001-12-10  Akim Demaille  <akim@epita.fr>
1397
1398         * src/muscle_tab.c (muscle_init): NULL is a better default than
1399         `"0"'.
1400
1401 2001-12-10  Akim Demaille  <akim@epita.fr>
1402
1403         * src/reader.c (reader): Calling symbols_output once is enough.
1404
1405 2001-12-10  Akim Demaille  <akim@epita.fr>
1406
1407         Now that states have a complete set of members, the linked list of
1408         reductions is useless: just fill directly the state's reductions
1409         member.
1410
1411         * src/state.h (struct reductions): Remove member `number' and
1412         `next'.
1413         * src/LR0.c (first_reduction, last_reduction): Remove.
1414         (save_reductions): Don't link the new reductions, store them in
1415         this_state.
1416         * src/lalr.c (set_state_table): No need to attach reductions to
1417         states, it's already done.
1418         * src/output.c (output_actions): No longer free the shifts, then
1419         the reductions, then the states: free all the states and their
1420         members.
1421
1422 2001-12-10  Akim Demaille  <akim@epita.fr>
1423
1424         * src/options.c (OPTN, DRTV, BOTH): New.
1425         (option_table): Use them.
1426
1427         * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
1428         the job of system.h.
1429         * src/options.c: Don't include stdio.h and xalloc.h for the same
1430         reasons.
1431
1432 2001-12-10  Akim Demaille  <akim@epita.fr>
1433
1434         * src/output.c (output, prepare): Make sure the values of the
1435         muscles `action' and `prologue' are 0-terminated.
1436
1437 2001-12-10  Akim Demaille  <akim@epita.fr>
1438
1439         Clean up GCC warnings.
1440
1441         * src/reader.c (copy_action): `buf' is not used.
1442         (parse_skel_decl): Be static.
1443         * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
1444         * src/options.h (create_long_option_table): Have a real prototype.
1445         * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
1446         (hash_delete_at): Return const void *.
1447         Adjust casts to preserve the const.
1448
1449 2001-12-10  Akim Demaille  <akim@epita.fr>
1450
1451         * configure.in: Require 2.52g.
1452         M4 is not needed, but AUTOM4TE is.
1453         * m4/m4.m4: Remove.
1454         * tests/Makefile.am: Adjust.
1455
1456 2001-12-10  Akim Demaille  <akim@epita.fr>
1457
1458         One structure for states is enough, even though theoretically
1459         there are LR(0) states and LALR(1) states.
1460
1461         * src/lalr.h (state_t): Remove.
1462         (state_table): Be state_t **, not state_t *.
1463         * src/state.h (core, CORE_ALLOC): Rename as...
1464         (state_t, STATE_ALLOC): this.
1465         Add the LALR(1) members: shifts, reductions, errs.
1466         * src/LR0.c (state_table): Rename as...
1467         (state_hash): this, to avoid name clashes with the global
1468         `state_table'.
1469         * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
1470         * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

1473
1474         Bison dumps core on bash.y.
1475         Reported by Pascal Bart.
1476
1477         * src/warshall.c (bitmatrix_print): New.
1478         (TC): Use it.
1479         When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
1480         j must be the outer loop.
1481         * tests/regression.at (Broken Closure): New.
1482
1483 2001-12-05  Akim Demaille  <akim@epita.fr>
1484
1485         * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
1486         its argument.
1487         Reported by Peter Hámorský.
1488
1489 2001-12-05  Akim Demaille  <akim@epita.fr>

1492         (resolve_sr_conflict): Adjust.
1493         * src/lalr.h (state_t.reduction_table, state_t.shift_table):
1494         Rename as...
1495         (state_t.reductions, state_t.shifts): this.
1496
1497 2001-12-05  Akim Demaille  <akim@epita.fr>
1498
1499         * src/reduce.c (reduce_grammar_tables): No longer disable the
1500         removal of useless rules via CPP but via `if (0)', so that the
1501         compiler still check the code is valid.
1502         For instance, it should have noticed `rline' no longer exists: use
1503         the `line' member of rule_t.
1504         * src/gram.c (dummy, rline): Remove, unused.
1505
1506 2001-12-05  Akim Demaille  <akim@epita.fr>
1507
1508         * src/output.c (pack_vector): Use assert, not berror.
1509         * src/main.c (berror): Remove, unused.
1510
1511 2001-12-05  Akim Demaille  <akim@epita.fr>
1512
1513         New experimental feature: if --verbose --trace output all the
1514         items of a state, not only its kernel.
1515
1516         * src/print.c (print_core): If `trace_flag', then invoke closure
1517         before outputting the items of the state (print_core is no longer
1518         a correct name them).
1519         (print_results): Invoke new_closure/free_closure if needed.
1520
1521 2001-12-05  Akim Demaille  <akim@epita.fr>
1522
1523         * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
1524         * src/closure.c, src/closure.h (itemsetsize): Rename as...
1525         (nitemset): for consistency with the rest of the project.
1526
1527 2001-12-05  Akim Demaille  <akim@epita.fr>
1528
1529         * src/closure.c (print_closure): Improve.
1530         (closure): Use it for printing input and output.
1531
1532 2001-12-05  Akim Demaille  <akim@epita.fr>
1533
1534         * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
1535         indexed by nonterminals.
1536
1537 2001-12-05  Akim Demaille  <akim@epita.fr>
1538
1539         * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
1540         what it was!).
1541         * src/warshall.h: Remove accidental duplication of the content.
1542
1543 2001-12-05  Akim Demaille  <akim@epita.fr>
1544

1554
1555 2001-12-05  Akim Demaille  <akim@epita.fr>
1556
1557         * src/output.c (action_row): De-obfuscate
1558         using the good o' techniques: arrays not pointers, variable
1559         locality, BITISSET, RESETBIT etc.
1560
1561 2001-12-05  Akim Demaille  <akim@epita.fr>
1562
1563         Pessimize the code to simplify it: from now on, all the states
1564         have a valid SHIFTS, which NSHIFTS is possibly 0.
1565
1566         * src/LR0.c (shifts_new): Be global and move to..
1567         * src/state.c, src/state.h: here.
1568         * src/conflicts, src/lalr.c, src/output.c, src/print.c,
1569         * src/print_graph: Adjust.
1570
1571 2001-12-05  Akim Demaille  <akim@epita.fr>
1572
1573         * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
1574         * src/conflicts.c: Use it.
1575         Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
1576         incorrectly ``simplified''.
1577
1578 2001-12-05  Akim Demaille  <akim@epita.fr>
1579
1580         * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
1581         using the good o' techniques: arrays not pointers, variable
1582         locality, BITISSET, RESETBIT etc.
1583
1584 2001-12-05  Akim Demaille  <akim@epita.fr>
1585
1586         * src/state.h (SHIFT_SYMBOL): New.
1587         * src/conflicts.c: Use it to deobfuscate.
1588
1589 2001-12-05  Akim Demaille  <akim@epita.fr>
1590
1591         * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
1592         (print_reductions): De-obfuscate using the good o' techniques:
1593         arrays not pointers, variable locality, BITISSET.
1594
1595 2001-12-05  Akim Demaille  <akim@epita.fr>
1596
1597         * src/conflicts.c (print_reductions): Arrays, not pointers.
1598         Use BITISSET.
1599

1605

1617
1618         * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
1619         * src/lalr.c: Use them.
1620
1621 2001-12-05  Akim Demaille  <akim@epita.fr>
1622
1623         * src/LR0.c (augment_automaton): Formatting changes.
1624         Better variable locality.
1625
1626 2001-12-05  Akim Demaille  <akim@epita.fr>
1627
1628         * src/lalr.c (matrix_print): New.
1629         (transpose): Use it.
1630         Use arrays instead of pointers.
1631
1632 2001-12-05  Akim Demaille  <akim@epita.fr>
1633
1634         * src/lalr.c (maxrhs): Move to...
1635         * src/gram.c, src/gram.h (ritem_longest_rhs): here.
1636         * src/lalr.c (build_relations): Adjust.
1637
1638 2001-12-05  Akim Demaille  <akim@epita.fr>
1639
1640         * src/lalr.c (transpose): Free the memory allocated to the
1641         argument, as it is replaced by the results by the unique caller.
1642         (build_relations): Merely invoke transpose: it handles the memory
1643         deallocation.
1644         Improve variable locality.
1645         Avoid variables used as mere abbreviations.
1646         (compute_lookaheads): Use arrays instead of pointers.
1647
1648 2001-12-05  Akim Demaille  <akim@epita.fr>
1649
1650         * src/lalr.c (initialize_F): Improve variable locality.
1651         Avoid variables used as mere abbreviations.
1652
1653 2001-12-05  Akim Demaille  <akim@epita.fr>
1654
1655         * src/derives.c (print_derives): Display the ruleno.
1656         * src/lalr.c (initialize_F, transpose): Better variable locality
1657         to improve readability.
1658         Avoid variables used as mere abbreviations.
1659
1660 2001-12-05  Akim Demaille  <akim@epita.fr>
1661
1662         * src/lalr.c (traverse): Use arrays instead of pointers.

1664 2001-12-05  Akim Demaille  <akim@epita.fr>
1665
1666         * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
1667         the handling of squeue.
1668         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1669
1670 2001-12-05  Akim Demaille  <akim@epita.fr>
1671
1672         Because useless nonterminals are now kept alive (instead of being
1673         `destroyed'), we now sometimes examine them, and store information
1674         related to them.  Hence we need to know their number, and adjust
1675         memory allocations.
1676
1677         * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
1678         static.
1679         * src/LR0.c (allocate_itemsets): The memory allocated to
1680         `symbol_count' was used for two different purpose: once to count
1681         the number of occurrences of each symbol, and later reassigned to
1682         `shift_symbol', containing the symbol that can be shifted from a
1683         given state.
1684         Deobfuscate, i.e., allocate, use and free `symbol_count' here
1685         only, and...
1686         (new_itemsets): Allocate `shift_symbol' here.
1687         (allocate_itemsets): symbol_count includes useless nonterminals.
1688         Make room for them.
1689         (free_storage): Use `free', not `XFREE', for pointers that cannot
1690         be null.
1691
1692 2001-12-05  Akim Demaille  <akim@epita.fr>
1693
1694         * src/nullable.c (set_nullable): Deobfuscate the handling of
1695         ritem.
1696         `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
1697
1698 2001-12-05  Akim Demaille  <akim@epita.fr>
1699
1700         * src/gram.c, src/gram.h (ritem_print): New.
1701         * src/gram.c (dummy): Remove, now there is actual code in gram.c.
1702         (This useless function was defined only to work around VMS linkers
1703         that can't handle compilation units with variables only).
1704         * src/reduce.c (dump_grammar): Use it to trace the construction of
1705         ritem.
1706
1707 2001-12-04  Paul Eggert  <eggert@twinsun.com>
1708
1709         * src/bison.simple (union yyalloc): Change member names
1710         to be the same as the stack names.
1711         (yyparse): yyptr is now union yyalloc *, not char *.
1712         (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
1713         and may generate better code on some machines.
1714         (yystpcpy): Use prototype if __STDC__ is defined, not just
1715         if __cplusplus is defined.
1716
1717 2001-11-30  Akim Demaille  <akim@epita.fr>
1718
1719         * configure.in (WARNING_CFLAGS): Add -Werror when possible.
1720         (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
1721         Gettext doesn't compile cleanly, and dies with -Werror.
1722         * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
1723         Include WARNING_CFLAGS here.
1724         * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
1725         before being defined.
1726
1727 2001-11-27  Paul Eggert  <eggert@twinsun.com>
1728
1729         * lib/quotearg.h (quotearg_n, quotearg_n_style):
1730         First arg is int, not unsigned.
1731         * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
1732         (SIZE_MAX, UINT_MAX): New macros.
1733         (quotearg_n_options): Abort if N is negative.
1734         Avoid overflow check on hosts where size_t is 64 bits and int
1735         is 32 bits, as overflow is impossible there.
1736         Fix off-by-one typo that caused unnecessary reallocation.
1737
1738 2001-11-29  Paul Eggert  <eggert@twinsun.com>
1739
1740         Name space cleanup in generated parser.
1741
1742         * doc/bison.texinfo (Bison Parser): Discuss system headers
1743         and their effect on the user name space.
1744
1745         * src/bison.simple:
1746         (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
1747         YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
1748         i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
1749
1750         (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
1751         on user names when possible.
1752
1753         (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
1754         Simplify test for whather <alloca.h> exists.
1755
1756         (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
1757
1758         (<stdio.h>): Include if YYDEBUG.
1759
1760         (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
1761         ! defined (yyoverflow) && ! defined (yymemcpy).
1762
1763         (yymemcpy, yyparse): Rename local variables as needed so that
1764         they all begin with 'yy'.
1765
1766         (yystrlen, yystpcpy): New functions.
1767
1768         (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
1769         All uses changed.
1770
1771         (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
1772         instead of relying on string.h functions.  Use YYSTACK_ALLOC
1773         and YYSTACK_FREE instead of malloc and free.
1774
1775 2001-11-30  Akim Demaille  <akim@epita.fr>
1776
1777         * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

1784
1785 2001-11-30  Akim Demaille  <akim@epita.fr>
1786
1787         * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
1788         if body instead of `;' to pacify GCC's warnings.
1789
1790 2001-11-30  Akim Demaille  <akim@epita.fr>
1791
1792         Instead of mapping the LHS of unused rules to -1, keep the LHS
1793         valid, but flag the rules as invalid.
1794
1795         * src/gram.h (rule_t): `useful' is a new member.
1796         * src/print.c (print_grammar): Adjust.
1797         * src/derives.c (set_derives): Likewise.

1825         * src/bison.simple (YYSTACK_REALLOC): Remove.
1826         (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
1827         (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
1828         New macros.
1829         (union yyalloc): New type.
1830         (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
1831         an arbitrary restriction on hosts where size_t is wider than int.
1832
1833         (yyparse): Don't dump core if alloca or malloc fails; instead, report
1834         a parser stack overflow.  Allocate just one block of memory for all
1835         three stacks, instead of allocating three blocks; this typically is
1836         faster and reduces fragmentation.
1837
1838         Do not limit the number of items in the stack to a value that fits
1839         in 'int', as this is an arbitrary limit on hosts with 64-bit
1840         size_t and 32-bit int.

1902         * src/closure.c (closure): No longer optimize the special case

3596 2001-07-08  Pascal Bart  <pascal.bart@epita.fr>
3597

3599         between signed and unsigned'.
3600
3601 2001-07-05  Pascal Bart  <pascal.bart@epita.fr>
3602
3603         * src/getargs.h (raw_flag): Remove.
3604         * src/getargs.c: Die on `-r'/`--raw'.
3605         * src/lex.c (parse_percent_token): Die on `%raw'.
3606         * src/reader.c (output_token_defines): Suppress call to `raw_flag'.
3607         * tests/calc.at: Suppress test with option `--raw'.
3608
3609 2001-07-14  Akim Demaille  <akim@epita.fr>
3610
3611         * config/: New.
3612         * configure.in: Require Autoconf 2.50.
3613         Update to gettext 0.10.38.
3614
3615 2001-03-16  Akim Demaille  <akim@epita.fr>
3616
3617         * doc/bison.texinfo: ANSIfy the examples.
3618
3619 2001-03-16  Akim Demaille  <akim@epita.fr>
3620
3621         * getargs.c (skeleton): New variable.
3622         (longopts): --skeleton is a new option.
3623         (shortopts, getargs): -S is a new option.
3624         * getargs.h: Declare skeleton.
3625         * output.c (output_parser): Use it.
3626
3627 2001-03-16  Akim Demaille  <akim@epita.fr>
3628
3629         * m4/strerror_r.m4: New.
3630         * m4/error.m4: Run AC_FUNC_STRERROR_R.

3632
3633 2001-03-16  Akim Demaille  <akim@epita.fr>

3636
3637 2001-02-21  Akim Demaille  <akim@epita.fr>
3638
3639         * src/reader.c (gensym): `gensym_count' is your own.
3640         Use a static buf to create the symbol name, as token_buffer is no
3641         longer a buffer.
3642
3643 2001-02-08  Akim Demaille  <akim@epita.fr>
3644
3645         * src/conflicts.c (conflict_report): Be sure not to append to res
3646         between two calls, which could happen if both first sprintf were
3647         skipped, but not the first cp += strlen.
3648
3649 2001-02-08  Akim Demaille  <akim@epita.fr>
3650
3651         * lib/memchr.c, lib/stpcpy.c, lib/strndup.c, lib/strnlen.c:
3652         New, from fileutils 4.0.37.
3653         * configure.in: Require Autoconf 2.49c.  I took some time before
3654         making this decision.  This is the only way out for portability
3655         issues in Bison, it would mean way too much duplicate effort to
3656         import in Bison features implemented in 2.49c since 2.13.
3657         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
3658
3659 2001-02-02  Akim Demaille  <akim@epita.fr>
3660
3661         * lib/malloc.c, lib/realloc.c: New, from the fileutils 4.0.37.

3664 2001-01-19  Akim Demaille  <akim@epita.fr>
3665
3666         Get rid of the ad hoc handling of token_buffer in the scanner: use
3667         the obstacks.
3668
3669         * src/lex.c (token_obstack): New.
3670         (init_lex): Initialize it.  No longer call...
3671         (grow_token_buffer): this.  Remove it.
3672         Adjust all the places which used it to use the obstack.
3673
3674 2001-01-19  Akim Demaille  <akim@epita.fr>
3675
3676         * src/lex.h: Rename all the tokens:
3677         s/\bENDFILE\b/tok_eof/g;
3678         s/\bIDENTIFIER\b/tok_identifier/g;
3679         etc.
3680         Let them be enums, not #define, to ease debugging.
3681         Adjust all the code.
3682
3683 2001-01-18  Akim Demaille  <akim@epita.fr>
3684
3685         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
3686         * src/lex.c (maxtoken, grow_token_buffer): Static.
3687
3688 2001-01-18  Akim Demaille  <akim@epita.fr>
3689
3690         Since we now use obstacks, more % directives can be enabled.
3691
3692         * src/lex.c (percent_table): Also accept `%yacc',
3693         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
3694         `%debug'.
3695         Handle the actions for `%semantic_parser' and `%pure_parser' here,
3696         instead of returning a token.
3697         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
3698         * src/reader.c (read_declarations): Adjust.
3699         * src/files.c (open_files): Don't call `compute_base_names', don't
3700         compute `attrsfile' since they depend upon data which might be
3701         *in* the input file now.
3702         (output_files): Do it here.
3703         * src/output.c (output_headers): Document the fact that this patch
3704         introduces a guaranteed SEGV for semantic parsers.
3705         * doc/bison.texinfo: Document them.
3706         * tests/suite.at: Exercise these %options.
3707
3708 2000-12-20  Akim Demaille  <akim@epita.fr>
3709
3710         Also handle the output file (--verbose) with obstacks.
3711
3712         * files.c (foutput): Remove.
3713         (output_obstack): New.
3714         Adjust all dependencies.
3715         * src/conflicts.c: Return a string.
3716         * src/system.h (obstack_grow_string): Rename as...
3717         (obstack_sgrow): this.  Be ready to work with non literals.
3718         (obstack_fgrow4): New.
3719
3720 2000-12-20  Akim Demaille  <akim@epita.fr>
3721
3722         * src/files.c (open_files): Fix the computation of short_base_name
3723         in the case of `-o foo.tab.c'.
3724
3725 2000-12-20  Akim Demaille  <akim@epita.fr>
3726
3727         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
3728         (copy_dollar): Now that everything uses obstacks, get rid of the
3729         FILE * parameters.
3730
3731 2000-12-20  Akim Demaille  <akim@epita.fr>
3732
3733         * src/files.c (open_files): Actually the `.output' file is based
3734         on the short_base_name, not base_name.
3735         * tests/suite.at (Checking output file names): Adjust.
3736
3737 2000-12-20  Akim Demaille  <akim@epita.fr>
3738
3739         * src/bison.s1: Remove, we now use directly...
3740         * src/bison.simple: this.
3741         * src/Makefile.am: Use pkgdata instead of data.
3742
3743 2000-12-20  Akim Demaille  <akim@epita.fr>

3754         vars.
3755         (open_files): Don't compute them.
3756         (output_files): Adjust.
3757         (base_name, short_base_name): Be global.
3758         Adjust dependencies.
3759
3760 2000-12-19  Akim Demaille  <akim@epita.fr>
3761
3762         * src/files.c (strsuffix): New.
3763         (stringappend): Be just like strcat but allocate.
3764         (base_names): Eve out from open_files.
3765         Try to simplify the rather hairy computation of base_name and
3766         short_base_name.
3767         (open_files): Use it.
3768         * tests/suite.at (Checking output file names): New test.
3769
3770 2000-12-19  Akim Demaille  <akim@epita.fr>

3775         `$'.
3776         * src/bison.s1: s/$/%% actions/.
3777         * src/bison.hairy: Likewise.
3778
3779 2000-12-19  Akim Demaille  <akim@epita.fr>
3780
3781         * src/output.c (output_parser): Compute the `#line' lines when
3782         there are.
3783         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
3784         Suggested by Hans Aberg.
3785
3786 2000-12-19  Akim Demaille  <akim@epita.fr>
3787
3788         Let the handling of the skeleton files be local to the procedures
3789         that use it.
3790
3791         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
3792         longer static.
3793         (fparser, open_extra_files): Remove.

3802

3805
3806 2000-12-19  Akim Demaille  <akim@epita.fr>
3807
3808         * src/files.c (open_files): Yipee!  We no longer need all the code
3809         looking for `/tmp' since we have no tmp file.
3810
3811 2000-12-19  Akim Demaille  <akim@epita.fr>
3812
3813         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

3826
3827         * src/reader.c (copy_definition, parse_union_decl, copy_action)
3828         (copy_guard): Quote the file names.

3834         to escape special characters when outputting filenames.
3835         (ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.

3838 2000-11-17  Akim Demaille  <akim@epita.fr>
3839
3840         * lib/obstack.h: Formatting changes.
3841         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
3842         prevents type checking.
3843         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
3844         cast the value to (void *): assigning a `foo *' to a `void *'
3845         variable is valid.
3846         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
3847         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

3863
3864         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

3882
3883 2000-11-07  Akim Demaille  <akim@epita.fr>
3884
3885         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
3886         Merge in a single CPP if/else.
3887
3888 2000-11-07  Akim Demaille  <akim@epita.fr>
3889
3890         * src/output.c (output): Remove useless variables.
3891         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
3892         argument `data' for consistency with the prototypes.
3893         Qualify it `const'.
3894         (obstack_copy, obstack_copy0): Rename the second argument as
3895         `address' for consistency.  Qualify it `const'.
3896         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
3897         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
3898         `const' their input argument (`data' or `address').
3899         Adjust the corresponding macros to include `const' in casts.
3900
3901 2000-11-03  Akim Demaille  <akim@epita.fr>
3902
3903         * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

3905         Adjust dependencies.
3906
3907 2000-11-03  Akim Demaille  <akim@epita.fr>
3908
3909         For some reason, this was not applied.
3910
3911         * src/files.c [VMS]: No longer include `ssdef.h', no longer define
3912         `unlink': it's no longer used.
3913
3914 2000-11-03  Akim Demaille  <akim@epita.fr>
3915
3916         * src/files.c (skeleton_find): New function, eved out of...

3924         (done): Rename as...
3925         (output_files): this.
3926         Use `obstack_save'.
3927         * src/main.c (main): Don't use `atexit' to register `done', since
3928         it no longer has to remove tmp files, just call `output_files'
3929         when there are no errors.
3930
3931 2000-11-02  Akim Demaille  <akim@epita.fr>
3932

4034         When a literal string is used to define two different tokens,
4035         `bison -v' segfaults.
4036         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
4037
4038         * tests/regression.m4: New file.
4039         Include the core of the sample provided by Piotr Gackiewicz.

4041         properly.

4044
4045         * src/reader.c (parse_expect_decl): Keep `count' within the size
4046         of `buffer'.
4047         From Neil Booth.
4048
4049 2000-10-02  Paul Eggert  <eggert@twinsun.com>
4050
4051         * bison.s1 (yyparse): Assign the default value
4052         unconditionally, to avoid a GCC warning and make the parser a
4053         tad smaller.
4054
4055 2000-10-02  Akim Demaille  <akim@epita.fr>
4056

4061
4062         * src/derives.c, src/print.c, src/reduce.c: To ease the
4063         translation, move some `\n' out of the translated strings.
4064
4065 2000-10-02  Akim Demaille  <akim@epita.fr>
4066
4067         The location tracking mechanism is precious for parse error
4068         messages.  Nevertheless, it is enabled only when `@n' is used in
4069         the grammar, which is a different issue (you can use it in error
4070         message, but not in the grammar per se).  Therefore, there should
4071         be another means to enable it.
4072
4073         * src/getargs.c (getargs): Support `--locations'.
4074         (usage): Report it.
4075         * src/getargs.h (locationsflag): Export it.
4076         * src/lex.c (percent_table): Support `%locations'.
4077         * src/reader.c (yylsp_needed): Remove this variable, now replaced
4078         with `locationsflag'.
4079         * doc/bison.texinfo: Document `--locations' and `%locations'.
4080         Sort the options.
4081         * tests/calc.m4: Test it.
4082
4083         For regularity of the names, replace each
4084         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
4085         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
4086         In addition replace each `flag' with `_flag'.
4087
4088 2000-10-02  Akim Demaille  <akim@epita.fr>
4089
4090         Also test parse error messages, including with YYERROR_VERBOSE.
4091
4092         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
4093         associative).
4094         Use it to check the computations.
4095         Use it to check `nonassoc' is honored.
4096         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
4097         `--yyerror-verbose'.
4098         (_AT_CHECK_CALC): Adjust to this option.
4099         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
4100
4101 2000-10-02  Akim Demaille  <akim@epita.fr>
4102
4103         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
4104         the latter demonstrates a flaw in the handling of non debugging
4105         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
4106         was used in order to simplify:
4107
4108         #if YYDEBUG
4109         if (yydebug)
4110         {
4111         ...
4112         }
4113         #endif
4114
4115         into
4116
4117         if (yydebug)
4118         {
4119         ...
4120         }
4121
4122         unfortunately this leads to a CPP conflict when
4123         `--name-prefix=foo' is used since it produces `#define yydebug
4124         foodebug'.
4125
4126         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
4127         (YYDPRINTF): New macro.
4128         Spread its use.
4129         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
4130         the bison options.
4131         Also test `--verbose', `--defines' and `--name-prefix'.
4132
4133 2000-10-02  Akim Demaille  <akim@epita.fr>
4134
4135         Improve the readability of the produced parsers.
4136
4137         * src/bison.s1: Formatting changes.
4138         Improve the comment related to the `$' mark.
4139         (yydefault): Don't fall through to `yyresume': `goto' there.
4140         * src/output.c (output_parser): When the `$' is met, skip the end
4141         of its line.
4142         New variable, `number_of_dollar_signs', to check there's exactly
4143         one `$' in the parser skeleton.
4144
4145 2000-10-02  Akim Demaille  <akim@epita.fr>
4146
4147         * lib/xstrdup.c: New file, from the fileutils.
4148         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
4149         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
4150         instead of strlen + xmalloc + strcpy.
4151         * src/symtab.c (copys): Remove, use xstrdup instead.
4152
4153 2000-10-02  Akim Demaille  <akim@epita.fr>
4154
4155         * src/gram.h (associativity): New enum type which replaces the
4156         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
4157         `right_assoc', `left_assoc' and `non_assoc'.
4158         Adjust all dependencies.
4159         * src/reader.c: Formatting changes.
4160         (LTYPESTR): Don't define it, use it as a literal in
4161         `reader_output_yylsp'.
4162         * src/symtab.h (symbol_class): New enum type which replaces the
4163         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
4164         `sunknown', `stoken and `snterm'.
4165
4166 2000-10-02  Akim Demaille  <akim@epita.fr>
4167
4168         * src/getargs.c (fixed_outfiles): Rename as...
4169         (yaccflag): for consistency and accuracy.
4170         Adjust dependencies.
4171
4172 2000-10-02  Akim Demaille  <akim@epita.fr>
4173
4174         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
4175         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
4176         difficult and introduced a lot of core dump.  It turns out that
4177         Bison used an implementation of `xmalloc' based on `calloc', and
4178         at various places it does depend upon the initialization to 0.  I
4179         have not tried to isolate the pertinent places, and all the former
4180         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
4181         someone should address this issue.
4182
4183         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
4184         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
4185         files.
4186         Adjust dependencies.

4188         Propagate.

4190 2000-10-02  Akim Demaille  <akim@epita.fr>
4191
4192         Various anti-`extern in *.c' changes.

4195
4196 2000-10-02  Akim Demaille  <akim@epita.fr>
4197
4198         * src/state.h (nstates, final_state, first_state, first_shift)
4199         (first_reduction): Move their exportation from here...
4200         * src/LR0.h: to here.

4202         * src/getargs.c (statisticsflag): New variable.

4276 2000-10-02  Akim Demaille  <akim@epita.fr>
4277
4278         * src/output.c (token_actions): Introduce a temporary array,

4280         output_short_table.
4281
4282 2000-10-02  Akim Demaille  <akim@epita.fr>
4283
4284         `user_toknums' is output as a `short[]' in `output.c', while it is
4285         defined as a `int[]' in `reader.c'.  For consistency with the
4286         other output tables, `user_toknums' is now defined as a table of
4287         shorts.

4302         order to get rid of the `static' prototypes.
4303         No longer use `register'.
4304         * src/output.h: New file.
4305         Propagate its inclusion in files explicitly prototyping functions
4306         from output.c.

4496
4497 2000-03-17  Akim Demaille  <akim@epita.fr>
4498
4499         On syntax errors, report the token on which we choked.

4521         copy_comment.  Removed now unused `match', `ended',
4522         `cplus_comment'.
4523         (copy_comment, copy_string): Moved, to be visible from
4524         copy_definition.

4527

4550
4551         Change the handling of @s so that they behave exactly like $s.
4552         There is now a pseudo variable @$ (readble and writable), location
4553         of the lhs of the rule (by default ranging from the location of
4554         the first symbol of the rhs, to the location of the last symbol,
4555         or, if the rhs is empty, YYLLOC).
4556
4557         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
4558         yyval.
4559         (yyparse): When providing a default semantic action, provide a
4560         default location action.
4561         (after the $): No longer change `*YYLSP', just stack YYLOC the
4562         same way you stack YYVAL.
4563         * src/reader.c (read_declarations): Use warns.
4564         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
4565         (copy_action, case '@'): Likewise.
4566         Use a standard error message, to save useless work from
4567         translators.
4568
4569 2000-03-17  Akim Demaille  <akim@epita.fr>

4588
4589         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
4590         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
4591         One `#if YYDEBUG' remains, since it uses variables which are
4592         defined only if `YYDEBUG != 0'.
4593
4594 2000-03-16  Akim Demaille  <akim@epita.fr>

4626         the proper line number and file name.
4627         (DEFS): Propagate the location of bison library files and of the
4628         locale files.
4629         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
4630         builddir.
4631         * acinclude.m4: Remove, replaced by the directory m4.
4632         * m4/Makefile.am (EXTRA_DIST): New variable.
