 254 2001-02-21  Akim Demaille  <akim@epita.fr>
 255
 256         * src/reader.c (gensym): `gensym_count' is your own.

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

 285
 286         * src/lex.c (token_obstack): New.
 287         (init_lex): Initialize it.  No longer call...

 295         s/\bIDENTIFIER\b/tok_identifier/g;
 296         etc.
 297         Let them be enums, not #define, to ease debugging.
 298         Adjust all the code.
 299
 300 2001-01-18  Akim Demaille  <akim@epita.fr>
 301

 304
 305 2001-01-18  Akim Demaille  <akim@epita.fr>
 306
 307         Since we now use obstacks, more % directives can be enabled.
 308
 309         * src/lex.c (percent_table): Also accept `%yacc',
 310         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 311         `%debug'.
 312         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 313         instead of returning a token.
 314         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 315         * src/reader.c (read_declarations): Adjust.
 316         * src/files.c (open_files): Don't call `compute_base_names', don't
 317         compute `attrsfile' since they depend upon data which might be
 318         *in* the input file now.
 319         (output_files): Do it here.
 320         * src/output.c (output_headers): Document the fact that this patch
 321         introduces a guaranteed SEGV for semantic parsers.

 333         * src/system.h (obstack_grow_string): Rename as...
 334         (obstack_sgrow): this.  Be ready to work with non literals.
 335         (obstack_fgrow4): New.
 336
 337 2000-12-20  Akim Demaille  <akim@epita.fr>

 339         * src/files.c (open_files): Fix the computation of short_base_name

 346         FILE * parameters.
 347
 348 2000-12-20  Akim Demaille  <akim@epita.fr>
 349
 350         * src/files.c (open_files): Actually the `.output' file is based
 351         on the short_base_name, not base_name.
 352         * tests/suite.at (Checking output file names): Adjust.
 353
 354 2000-12-20  Akim Demaille  <akim@epita.fr>

 357         * src/bison.simple: this.
 358         * src/Makefile.am: Use pkgdata instead of data.
 359
 360 2000-12-20  Akim Demaille  <akim@epita.fr>
 361
 362         * src/files.c (guard_obstack): New.

 380         (stringappend): Be just like strcat but allocate.
 381         (base_names): Eve out from open_files.
 382         Try to simplify the rather hairy computation of base_name and
 383         short_base_name.

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

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

 423 2000-12-19  Akim Demaille  <akim@epita.fr>
 424
 425         * src/files.c (open_files): Yipee!  We no longer need all the code
 426         looking for `/tmp' since we have no tmp file.
 427
 428 2000-12-19  Akim Demaille  <akim@epita.fr>
 429
 430         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 431         New macros.

 435
 436         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 456
 457         * lib/obstack.h: Formatting changes.
 458         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 459         prevents type checking.
 460         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 461         cast the value to (void *): assigning a `foo *' to a `void *'
 462         variable is valid.
 463         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 464         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

 480
 481         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

 500 2000-11-07  Akim Demaille  <akim@epita.fr>
 501
 502         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 508         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
 509         argument `data' for consistency with the prototypes.
 510         Qualify it `const'.
 511         (obstack_copy, obstack_copy0): Rename the second argument as
 512         `address' for consistency.  Qualify it `const'.
 513         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 514         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 523
 524 2000-11-03  Akim Demaille  <akim@epita.fr>
 525
 526         For some reason, this was not applied.
 527
 528         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 540         * src/files.c (obstack_save): New function.
 541         (done): Rename as...
 542         (output_files): this.
 543         Use `obstack_save'.
 544         * src/main.c (main): Don't use `atexit' to register `done', since
 545         it no longer has to remove tmp files, just call `output_files'
 546         when there are no errors.
 547
 548 2000-11-02  Akim Demaille  <akim@epita.fr>

 593

 616
 617         * src/reader.c (copy_comment2): Expect the input stream to be on
 618         the `/' which is suspected to open a comment, instead of being
 619         called after `//' or `/*' was read.
 620         (copy_comment, copy_definition, parse_union_decl, copy_action)
 621         (copy_guard): Adjust.

 651         When a literal string is used to define two different tokens,
 652         `bison -v' segfaults.
 653         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 654
 655         * tests/regression.m4: New file.

 662         * src/reader.c (parse_expect_decl): Keep `count' within the size
 663         of `buffer'.
 664         From Neil Booth.
 665
 666 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 667
 668         * bison.s1 (yyparse): Assign the default value
 669         unconditionally, to avoid a GCC warning and make the parser a
 670         tad smaller.
 671
 672 2000-10-02  Akim Demaille  <akim@epita.fr>
 673
 674         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 677 2000-10-02  Akim Demaille  <akim@epita.fr>
 678
 679         * src/derives.c, src/print.c, src/reduce.c: To ease the
 680         translation, move some `\n' out of the translated strings.
 681
 682 2000-10-02  Akim Demaille  <akim@epita.fr>
 683
 684         The location tracking mechanism is precious for parse error
 685         messages.  Nevertheless, it is enabled only when `@n' is used in
 686         the grammar, which is a different issue (you can use it in error
 687         message, but not in the grammar per se).  Therefore, there should
 688         be another means to enable it.
 689
 690         * src/getargs.c (getargs): Support `--locations'.
 691         (usage): Report it.
 692         * src/getargs.h (locationsflag): Export it.
 693         * src/lex.c (percent_table): Support `%locations'.
 694         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 695         with `locationsflag'.
 696         * doc/bison.texinfo: Document `--locations' and `%locations'.
 697         Sort the options.
 698         * tests/calc.m4: Test it.
 699
 700         For regularity of the names, replace each
 701         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 702         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 703         In addition replace each `flag' with `_flag'.
 704
 705 2000-10-02  Akim Demaille  <akim@epita.fr>
 706
 707         Also test parse error messages, including with YYERROR_VERBOSE.
 708
 709         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 710         associative).
 711         Use it to check the computations.
 712         Use it to check `nonassoc' is honored.
 713         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 714         `--yyerror-verbose'.
 715         (_AT_CHECK_CALC): Adjust to this option.
 716         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 717
 718 2000-10-02  Akim Demaille  <akim@epita.fr>
 719
 720         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 721         the latter demonstrates a flaw in the handling of non debugging
 722         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 723         was used in order to simplify:
 724
 725         #if YYDEBUG
 726         if (yydebug)
 727         {
 728         ...
 729         }
 730         #endif
 731
 732         into
 733
 734         if (yydebug)
 735         {
 736         ...
 737         }
 738
 739         unfortunately this leads to a CPP conflict when
 740         `--name-prefix=foo' is used since it produces `#define yydebug
 741         foodebug'.
 742
 743         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 744         (YYDPRINTF): New macro.
 745         Spread its use.
 746         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 747         the bison options.
 748         Also test `--verbose', `--defines' and `--name-prefix'.
 749
 750 2000-10-02  Akim Demaille  <akim@epita.fr>
 751
 752         Improve the readability of the produced parsers.
 753
 754         * src/bison.s1: Formatting changes.

 758         of its line.

 779         * src/symtab.h (symbol_class): New enum type which replaces the

 791         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 792         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 793         difficult and introduced a lot of core dump.  It turns out that
 794         Bison used an implementation of `xmalloc' based on `calloc', and
 795         at various places it does depend upon the initialization to 0.  I
 796         have not tried to isolate the pertinent places, and all the former
 797         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 798         someone should address this issue.
 799
 800         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 801         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 897         output_short_table.
 898
 899 2000-10-02  Akim Demaille  <akim@epita.fr>
 900
 901         `user_toknums' is output as a `short[]' in `output.c', while it is
 902         defined as a `int[]' in `reader.c'.  For consistency with the
 903         other output tables, `user_toknums' is now defined as a table of
 904         shorts.
 905

 907         table.

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

 922         Propagate its inclusion in files explicitly prototyping functions

 946         Don't define PARAMS.
 947         * src/system.h: Define PARAMS.
 948         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 949         purpose of config.h.  system.h must not try to fix wrong
 950         definitions in config.h.

1136

1138         copy_comment.  Removed now unused `match', `ended',
1139         `cplus_comment'.
1140         (copy_comment, copy_string): Moved, to be visible from
1141         copy_definition.

1144
1145         * src/reader.c (copy_string): Declare `static inline'.  No

1167
1168         Change the handling of @s so that they behave exactly like $s.
1169         There is now a pseudo variable @$ (readble and writable), location
1170         of the lhs of the rule (by default ranging from the location of
1171         the first symbol of the rhs, to the location of the last symbol,
1172         or, if the rhs is empty, YYLLOC).
1173
1174         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1175         yyval.
1176         (yyparse): When providing a default semantic action, provide a
1177         default location action.
1178         (after the $): No longer change `*YYLSP', just stack YYLOC the
1179         same way you stack YYVAL.
1180         * src/reader.c (read_declarations): Use warns.
1181         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1182         (copy_action, case '@'): Likewise.
1183         Use a standard error message, to save useless work from
1184         translators.
1185
1186 2000-03-17  Akim Demaille  <akim@epita.fr>
1187

1205
1206         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1207         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1208         One `#if YYDEBUG' remains, since it uses variables which are
1209         defined only if `YYDEBUG != 0'.
1210
1211 2000-03-16  Akim Demaille  <akim@epita.fr>

1235         handled via src/Makefile.am.

1237         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1243         the proper line number and file name.
1244         (DEFS): Propagate the location of bison library files and of the
1245         locale files.
1246         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1247         builddir.
1248         * acinclude.m4: Remove, replaced by the directory m4.
1249         * m4/Makefile.am (EXTRA_DIST): New variable.
1250         * m4/gettext.m4: New file, from the fileutils.
