 236
 237         * src/reader.c (gensym): `gensym_count' is your own.
 238         Use a static buf to create the symbol name, as token_buffer is no

 242
 243         * src/conflicts.c (conflict_report): Be sure not to append to res

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

 265         the obstacks.
 266
 267         * src/lex.c (token_obstack): New.
 268         (init_lex): Initialize it.  No longer call...
 269         (grow_token_buffer): this.  Remove it.
 270         Adjust all the places which used it to use the obstack.

 273
 274         * src/lex.h: Rename all the tokens:

 276         s/\bIDENTIFIER\b/tok_identifier/g;
 277         etc.
 278         Let them be enums, not #define, to ease debugging.
 279         Adjust all the code.
 280
 281 2001-01-18  Akim Demaille  <akim@epita.fr>
 282
 283         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

 285
 286 2001-01-18  Akim Demaille  <akim@epita.fr>
 287
 288         Since we now use obstacks, more % directives can be enabled.
 289
 290         * src/lex.c (percent_table): Also accept `%yacc',
 291         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 292         `%debug'.
 293         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 294         instead of returning a token.
 295         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 296         * src/reader.c (read_declarations): Adjust.
 297         * src/files.c (open_files): Don't call `compute_base_names', don't
 298         compute `attrsfile' since they depend upon data which might be
 299         *in* the input file now.
 300         (output_files): Do it here.
 301         * src/output.c (output_headers): Document the fact that this patch
 302         introduces a guaranteed SEGV for semantic parsers.

 314         * src/system.h (obstack_grow_string): Rename as...
 315         (obstack_sgrow): this.  Be ready to work with non literals.
 316         (obstack_fgrow4): New.
 317
 318 2000-12-20  Akim Demaille  <akim@epita.fr>
 319
 320         * src/files.c (open_files): Fix the computation of short_base_name

 326         (copy_dollar): Now that everything uses obstacks, get rid of the
 327         FILE * parameters.
 328
 329 2000-12-20  Akim Demaille  <akim@epita.fr>
 330
 331         * src/files.c (open_files): Actually the `.output' file is based
 332         on the short_base_name, not base_name.
 333         * tests/suite.at (Checking output file names): Adjust.
 334
 335 2000-12-20  Akim Demaille  <akim@epita.fr>

 338         * src/bison.simple: this.
 339         * src/Makefile.am: Use pkgdata instead of data.
 340
 341 2000-12-20  Akim Demaille  <akim@epita.fr>
 342
 343         * src/files.c (guard_obstack): New.

 361         (stringappend): Be just like strcat but allocate.
 362         (base_names): Eve out from open_files.
 363         Try to simplify the rather hairy computation of base_name and
 364         short_base_name.
 365         (open_files): Use it.
 366         * tests/suite.at (Checking output file names): New test.

 384 2000-12-19  Akim Demaille  <akim@epita.fr>
 385
 386         Let the handling of the skeleton files be local to the procedures
 387         that use it.
 388
 389         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

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

 403
 404 2000-12-19  Akim Demaille  <akim@epita.fr>
 405
 406         * src/files.c (open_files): Yipee!  We no longer need all the code
 407         looking for `/tmp' since we have no tmp file.
 408
 409 2000-12-19  Akim Demaille  <akim@epita.fr>
 410
 411         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 412         New macros.
 413         * src/files.c (open_files): Less dependency on MSDOS etc.

 416
 417         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 437
 438         * lib/obstack.h: Formatting changes.
 439         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 440         prevents type checking.
 441         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 442         cast the value to (void *): assigning a `foo *' to a `void *'
 443         variable is valid.
 444         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 445         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 446         append characters.

 480
 481 2000-11-07  Akim Demaille  <akim@epita.fr>
 482
 483         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 490         argument `data' for consistency with the prototypes.
 491         Qualify it `const'.
 492         (obstack_copy, obstack_copy0): Rename the second argument as
 493         `address' for consistency.  Qualify it `const'.
 494         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 495         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 504
 505 2000-11-03  Akim Demaille  <akim@epita.fr>
 506
 507         For some reason, this was not applied.
 508
 509         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 521         * src/files.c (obstack_save): New function.
 522         (done): Rename as...
 523         (output_files): this.
 524         Use `obstack_save'.
 525         * src/main.c (main): Don't use `atexit' to register `done', since
 526         it no longer has to remove tmp files, just call `output_files'
 527         when there are no errors.
 528
 529 2000-11-02  Akim Demaille  <akim@epita.fr>

 597
 598         * src/reader.c (copy_comment2): Expect the input stream to be on
 599         the `/' which is suspected to open a comment, instead of being
 600         called after `//' or `/*' was read.
 601         (copy_comment, copy_definition, parse_union_decl, copy_action)

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

 645         From Neil Booth.
 646
 647 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 648
 649         * bison.s1 (yyparse): Assign the default value
 650         unconditionally, to avoid a GCC warning and make the parser a
 651         tad smaller.
 652
 653 2000-10-02  Akim Demaille  <akim@epita.fr>
 654
 655         * src/getargs.c (getargs): Don't dump `--help' on unrecognized

 659
 660         * src/derives.c, src/print.c, src/reduce.c: To ease the
 661         translation, move some `\n' out of the translated strings.
 662
 663 2000-10-02  Akim Demaille  <akim@epita.fr>
 664
 665         The location tracking mechanism is precious for parse error
 666         messages.  Nevertheless, it is enabled only when `@n' is used in
 667         the grammar, which is a different issue (you can use it in error
 668         message, but not in the grammar per se).  Therefore, there should
 669         be another means to enable it.
 670
 671         * src/getargs.c (getargs): Support `--locations'.
 672         (usage): Report it.
 673         * src/getargs.h (locationsflag): Export it.
 674         * src/lex.c (percent_table): Support `%locations'.
 675         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 676         with `locationsflag'.
 677         * doc/bison.texinfo: Document `--locations' and `%locations'.
 678         Sort the options.
 679         * tests/calc.m4: Test it.
 680
 681         For regularity of the names, replace each
 682         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 683         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 684         In addition replace each `flag' with `_flag'.
 685
 686 2000-10-02  Akim Demaille  <akim@epita.fr>
 687
 688         Also test parse error messages, including with YYERROR_VERBOSE.
 689
 690         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 691         associative).
 692         Use it to check the computations.
 693         Use it to check `nonassoc' is honored.
 694         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 695         `--yyerror-verbose'.
 696         (_AT_CHECK_CALC): Adjust to this option.
 697         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 698
 699 2000-10-02  Akim Demaille  <akim@epita.fr>
 700
 701         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 702         the latter demonstrates a flaw in the handling of non debugging
 703         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 704         was used in order to simplify:
 705
 706         #if YYDEBUG
 707         if (yydebug)
 708         {
 709         ...
 710         }
 711         #endif
 712
 713         into
 714
 715         if (yydebug)
 716         {
 717         ...
 718         }
 719
 720         unfortunately this leads to a CPP conflict when
 721         `--name-prefix=foo' is used since it produces `#define yydebug
 722         foodebug'.
 723
 724         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 725         (YYDPRINTF): New macro.
 726         Spread its use.
 727         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 728         the bison options.
 729         Also test `--verbose', `--defines' and `--name-prefix'.
 730
 731 2000-10-02  Akim Demaille  <akim@epita.fr>
 732
 733         Improve the readability of the produced parsers.
 734
 735         * src/bison.s1: Formatting changes.
 736         Improve the comment related to the `$' mark.
 737         (yydefault): Don't fall through to `yyresume': `goto' there.
 738         * src/output.c (output_parser): When the `$' is met, skip the end
 739         of its line.
 740         New variable, `number_of_dollar_signs', to check there's exactly
 741         one `$' in the parser skeleton.
 742
 743 2000-10-02  Akim Demaille  <akim@epita.fr>
 744
 745         * lib/xstrdup.c: New file, from the fileutils.
 746         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 747         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 748         instead of strlen + xmalloc + strcpy.

 752

 754         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with

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

 771
 772         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 773         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 774         difficult and introduced a lot of core dump.  It turns out that
 775         Bison used an implementation of `xmalloc' based on `calloc', and
 776         at various places it does depend upon the initialization to 0.  I
 777         have not tried to isolate the pertinent places, and all the former
 778         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 779         someone should address this issue.
 780
 781         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 782         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 877         YYDEFACT, that makes it possible for this function to use
 878         output_short_table.
 879
 880 2000-10-02  Akim Demaille  <akim@epita.fr>
 881
 882         `user_toknums' is output as a `short[]' in `output.c', while it is
 883         defined as a `int[]' in `reader.c'.  For consistency with the
 884         other output tables, `user_toknums' is now defined as a table of
 885         shorts.
 886

 888         table.

 903         Propagate its inclusion in files explicitly prototyping functions

 927         Don't define PARAMS.
 928         * src/system.h: Define PARAMS.
 929         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 930         purpose of config.h.  system.h must not try to fix wrong
 931         definitions in config.h.

1126         * src/reader.c (copy_string): Declare `static inline'.  No
1127         problems with inline, since it is checked by configure.
1128         (copy_comment): Likewise.
1129
1130 2000-03-17  Akim Demaille  <akim@epita.fr>
1131
1132         * src/reader.c (packsymbols): Formatting changes.
1133

1136         * src/reader.c (copy_comment): New function, factored out from:
1137         (copy_action): Use it.  Removed now unused `match', `ended',
1138         `cplus_comment'.

1146
1147 2000-03-17  Akim Demaille  <akim@epita.fr>
1148
1149         Change the handling of @s so that they behave exactly like $s.
1150         There is now a pseudo variable @$ (readble and writable), location
1151         of the lhs of the rule (by default ranging from the location of
1152         the first symbol of the rhs, to the location of the last symbol,
1153         or, if the rhs is empty, YYLLOC).
1154
1155         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1156         yyval.
1157         (yyparse): When providing a default semantic action, provide a
1158         default location action.
1159         (after the $): No longer change `*YYLSP', just stack YYLOC the
1160         same way you stack YYVAL.
1161         * src/reader.c (read_declarations): Use warns.
1162         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1163         (copy_action, case '@'): Likewise.
1164         Use a standard error message, to save useless work from
1165         translators.
1166
1167 2000-03-17  Akim Demaille  <akim@epita.fr>
1168
1169         * src/bison.s1: Formatting and cosmetics changes.

1174

1176         Makefile now handles them.
1177

1186
1187         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1188         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1189         One `#if YYDEBUG' remains, since it uses variables which are
1190         defined only if `YYDEBUG != 0'.
1191
1192 2000-03-16  Akim Demaille  <akim@epita.fr>

1216         handled via src/Makefile.am.
1217         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
1218         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
1219         autoheader.

1224         the proper line number and file name.
1225         (DEFS): Propagate the location of bison library files and of the
1226         locale files.
1227         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1228         builddir.
1229         * acinclude.m4: Remove, replaced by the directory m4.
1230         * m4/Makefile.am (EXTRA_DIST): New variable.
1231         * m4/gettext.m4: New file, from the fileutils.
