 271
 272         * src/reader.c (gensym): `gensym_count' is your own.

 277

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

 300         the obstacks.
 301
 302         * src/lex.c (token_obstack): New.
 303         (init_lex): Initialize it.  No longer call...
 304         (grow_token_buffer): this.  Remove it.
 305         Adjust all the places which used it to use the obstack.

 308
 309         * src/lex.h: Rename all the tokens:

 311         s/\bIDENTIFIER\b/tok_identifier/g;
 312         etc.
 313         Let them be enums, not #define, to ease debugging.
 314         Adjust all the code.
 315
 316 2001-01-18  Akim Demaille  <akim@epita.fr>
 317
 318         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 319         * src/lex.c (maxtoken, grow_token_buffer): Static.
 320
 321 2001-01-18  Akim Demaille  <akim@epita.fr>
 322
 323         Since we now use obstacks, more % directives can be enabled.
 324
 325         * src/lex.c (percent_table): Also accept `%yacc',
 326         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 327         `%debug'.
 328         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 329         instead of returning a token.
 330         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 331         * src/reader.c (read_declarations): Adjust.
 332         * src/files.c (open_files): Don't call `compute_base_names', don't
 333         compute `attrsfile' since they depend upon data which might be
 334         *in* the input file now.
 335         (output_files): Do it here.
 336         * src/output.c (output_headers): Document the fact that this patch
 337         introduces a guaranteed SEGV for semantic parsers.
 338         * doc/bison.texinfo: Document them.

 349         * src/system.h (obstack_grow_string): Rename as...
 350         (obstack_sgrow): this.  Be ready to work with non literals.
 351         (obstack_fgrow4): New.
 352
 353 2000-12-20  Akim Demaille  <akim@epita.fr>
 354
 355         * src/files.c (open_files): Fix the computation of short_base_name

 360         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 361         (copy_dollar): Now that everything uses obstacks, get rid of the
 362         FILE * parameters.
 363
 364 2000-12-20  Akim Demaille  <akim@epita.fr>
 365
 366         * src/files.c (open_files): Actually the `.output' file is based
 367         on the short_base_name, not base_name.
 368         * tests/suite.at (Checking output file names): Adjust.
 369
 370 2000-12-20  Akim Demaille  <akim@epita.fr>
 371
 372         * src/bison.s1: Remove, we now use directly...
 373         * src/bison.simple: this.

 385
 386         * src/files.c (outfile, defsfile, actfile): Removed as global
 387         vars.
 388         (open_files): Don't compute them.
 389         (output_files): Adjust.

 396         (stringappend): Be just like strcat but allocate.
 397         (base_names): Eve out from open_files.
 398         Try to simplify the rather hairy computation of base_name and

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

 419 2000-12-19  Akim Demaille  <akim@epita.fr>
 420
 421         Let the handling of the skeleton files be local to the procedures

 435
 436         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 439 2000-12-19  Akim Demaille  <akim@epita.fr>
 440
 441         * src/files.c (open_files): Yipee!  We no longer need all the code
 442         looking for `/tmp' since we have no tmp file.
 443
 444 2000-12-19  Akim Demaille  <akim@epita.fr>
 445
 446         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 447         New macros.
 448         * src/files.c (open_files): Less dependency on MSDOS etc.

 451
 452         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 472
 473         * lib/obstack.h: Formatting changes.
 474         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 475         prevents type checking.
 476         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 477         cast the value to (void *): assigning a `foo *' to a `void *'
 478         variable is valid.
 479         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 480         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 481         append characters.

 484

 515
 516 2000-11-07  Akim Demaille  <akim@epita.fr>
 517
 518         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 525         argument `data' for consistency with the prototypes.
 526         Qualify it `const'.
 527         (obstack_copy, obstack_copy0): Rename the second argument as
 528         `address' for consistency.  Qualify it `const'.
 529         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 530         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 538         Adjust dependencies.
 539
 540 2000-11-03  Akim Demaille  <akim@epita.fr>
 541
 542         For some reason, this was not applied.
 543
 544         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 556         * src/files.c (obstack_save): New function.
 557         (done): Rename as...
 558         (output_files): this.
 559         Use `obstack_save'.
 560         * src/main.c (main): Don't use `atexit' to register `done', since
 561         it no longer has to remove tmp files, just call `output_files'
 562         when there are no errors.
 563
 564 2000-11-02  Akim Demaille  <akim@epita.fr>

 590         (attrs_obstack): New.
 591         Adjust all dependencies.

 594 2000-11-01  Akim Demaille  <akim@epita.fr>
 595
 596         Introduce obstacks.

 609

 632
 633         * src/reader.c (copy_comment2): Expect the input stream to be on
 634         the `/' which is suspected to open a comment, instead of being
 635         called after `//' or `/*' was read.
 636         (copy_comment, copy_definition, parse_union_decl, copy_action)
 637         (copy_guard): Adjust.

 664
 665 2000-10-04  Akim Demaille  <akim@epita.fr>
 666
 667         When a literal string is used to define two different tokens,
 668         `bison -v' segfaults.
 669         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 670
 671         * tests/regression.m4: New file.

 678         * src/reader.c (parse_expect_decl): Keep `count' within the size
 679         of `buffer'.
 680         From Neil Booth.
 681
 682 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 683
 684         * bison.s1 (yyparse): Assign the default value
 685         unconditionally, to avoid a GCC warning and make the parser a
 686         tad smaller.
 687
 688 2000-10-02  Akim Demaille  <akim@epita.fr>
 689
 690         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 692
 693 2000-10-02  Akim Demaille  <akim@epita.fr>
 694
 695         * src/derives.c, src/print.c, src/reduce.c: To ease the
 696         translation, move some `\n' out of the translated strings.
 697
 698 2000-10-02  Akim Demaille  <akim@epita.fr>
 699
 700         The location tracking mechanism is precious for parse error
 701         messages.  Nevertheless, it is enabled only when `@n' is used in
 702         the grammar, which is a different issue (you can use it in error
 703         message, but not in the grammar per se).  Therefore, there should
 704         be another means to enable it.
 705
 706         * src/getargs.c (getargs): Support `--locations'.
 707         (usage): Report it.
 708         * src/getargs.h (locationsflag): Export it.
 709         * src/lex.c (percent_table): Support `%locations'.
 710         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 711         with `locationsflag'.
 712         * doc/bison.texinfo: Document `--locations' and `%locations'.
 713         Sort the options.
 714         * tests/calc.m4: Test it.
 715
 716         For regularity of the names, replace each
 717         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 718         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 719         In addition replace each `flag' with `_flag'.
 720
 721 2000-10-02  Akim Demaille  <akim@epita.fr>
 722
 723         Also test parse error messages, including with YYERROR_VERBOSE.
 724
 725         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 726         associative).
 727         Use it to check the computations.
 728         Use it to check `nonassoc' is honored.
 729         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 730         `--yyerror-verbose'.
 731         (_AT_CHECK_CALC): Adjust to this option.
 732         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 733
 734 2000-10-02  Akim Demaille  <akim@epita.fr>
 735
 736         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 737         the latter demonstrates a flaw in the handling of non debugging
 738         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 739         was used in order to simplify:
 740
 741         #if YYDEBUG
 742         if (yydebug)
 743         {
 744         ...
 745         }
 746         #endif
 747
 748         into
 749
 750         if (yydebug)
 751         {
 752         ...
 753         }

 755         unfortunately this leads to a CPP conflict when
 756         `--name-prefix=foo' is used since it produces `#define yydebug
 757         foodebug'.
 758
 759         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 760         (YYDPRINTF): New macro.
 761         Spread its use.
 762         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 763         the bison options.

 772         (yydefault): Don't fall through to `yyresume': `goto' there.
 773         * src/output.c (output_parser): When the `$' is met, skip the end
 774         of its line.
 775         New variable, `number_of_dollar_signs', to check there's exactly
 776         one `$' in the parser skeleton.

 788         * src/gram.h (associativity): New enum type which replaces the
 789         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with

 791         Adjust all dependencies.
 792         * src/reader.c: Formatting changes.
 793         (LTYPESTR): Don't define it, use it as a literal in

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

 806
 807         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 808         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 809         difficult and introduced a lot of core dump.  It turns out that
 810         Bison used an implementation of `xmalloc' based on `calloc', and
 811         at various places it does depend upon the initialization to 0.  I
 812         have not tried to isolate the pertinent places, and all the former
 813         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 814         someone should address this issue.
 815
 816         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 817         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 912         YYDEFACT, that makes it possible for this function to use
 913         output_short_table.
 914
 915 2000-10-02  Akim Demaille  <akim@epita.fr>
 916
 917         `user_toknums' is output as a `short[]' in `output.c', while it is
 918         defined as a `int[]' in `reader.c'.  For consistency with the
 919         other output tables, `user_toknums' is now defined as a table of
 920         shorts.
 921
 922         * src/reader.c (user_toknums): Be a short table instead of an int
 923         table.

 935         order to get rid of the `static' prototypes.

 937         * src/output.h: New file.
 938         Propagate its inclusion in files explicitly prototyping functions
 939         from output.c.

 962         Don't define PARAMS.
 963         * src/system.h: Define PARAMS.
 964         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 965         purpose of config.h.  system.h must not try to fix wrong
 966         definitions in config.h.

1127         * src/Makefile.am (bison.simple): Fix the awk program: quote only
1128         the file name, not the whole `#line LINE FILE'.
1129
1130 2000-03-17  Akim Demaille  <akim@epita.fr>
1131
1132         On syntax errors, report the token on which we choked.
1133
1134         * src/bison.s1 (yyparse): In the label yyerrlab, when
1135         YYERROR_VERBOSE, add yychar in msg.

1152

1154         copy_comment.  Removed now unused `match', `ended',
1155         `cplus_comment'.
1156         (copy_comment, copy_string): Moved, to be visible from
1157         copy_definition.
1158

1160
1161         * src/reader.c (copy_string): Declare `static inline'.  No

1183
1184         Change the handling of @s so that they behave exactly like $s.
1185         There is now a pseudo variable @$ (readble and writable), location
1186         of the lhs of the rule (by default ranging from the location of
1187         the first symbol of the rhs, to the location of the last symbol,
1188         or, if the rhs is empty, YYLLOC).
1189
1190         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1191         yyval.
1192         (yyparse): When providing a default semantic action, provide a
1193         default location action.
1194         (after the $): No longer change `*YYLSP', just stack YYLOC the
1195         same way you stack YYVAL.
1196         * src/reader.c (read_declarations): Use warns.
1197         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1198         (copy_action, case '@'): Likewise.
1199         Use a standard error message, to save useless work from
1200         translators.
1201
1202 2000-03-17  Akim Demaille  <akim@epita.fr>
1203
1204         * src/bison.s1: Formatting and cosmetics changes.

1221
1222         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1223         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1224         One `#if YYDEBUG' remains, since it uses variables which are
1225         defined only if `YYDEBUG != 0'.
1226
1227 2000-03-16  Akim Demaille  <akim@epita.fr>
1228
1229         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

1251         handled via src/Makefile.am.
1252         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
1253         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
1254         autoheader.

1259         the proper line number and file name.
1260         (DEFS): Propagate the location of bison library files and of the
1261         locale files.
1262         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1263         builddir.
1264         * acinclude.m4: Remove, replaced by the directory m4.
1265         * m4/Makefile.am (EXTRA_DIST): New variable.
1266         * m4/gettext.m4: New file, from the fileutils.
