 226
 227         * src/reader.c (gensym): `gensym_count' is your own.
 228         Use a static buf to create the symbol name, as token_buffer is no

 232

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

 255         the obstacks.
 256
 257         * src/lex.c (token_obstack): New.
 258         (init_lex): Initialize it.  No longer call...
 259         (grow_token_buffer): this.  Remove it.
 260         Adjust all the places which used it to use the obstack.

 263
 264         * src/lex.h: Rename all the tokens:

 266         s/\bIDENTIFIER\b/tok_identifier/g;
 267         etc.
 268         Let them be enums, not #define, to ease debugging.
 269         Adjust all the code.
 270
 271 2001-01-18  Akim Demaille  <akim@epita.fr>
 272
 273         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

 275
 276 2001-01-18  Akim Demaille  <akim@epita.fr>
 277
 278         Since we now use obstacks, more % directives can be enabled.
 279
 280         * src/lex.c (percent_table): Also accept `%yacc',
 281         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 282         `%debug'.
 283         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 284         instead of returning a token.
 285         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 286         * src/reader.c (read_declarations): Adjust.
 287         * src/files.c (open_files): Don't call `compute_base_names', don't
 288         compute `attrsfile' since they depend upon data which might be
 289         *in* the input file now.
 290         (output_files): Do it here.
 291         * src/output.c (output_headers): Document the fact that this patch
 292         introduces a guaranteed SEGV for semantic parsers.

 304         * src/system.h (obstack_grow_string): Rename as...
 305         (obstack_sgrow): this.  Be ready to work with non literals.
 306         (obstack_fgrow4): New.
 307
 308 2000-12-20  Akim Demaille  <akim@epita.fr>
 309
 310         * src/files.c (open_files): Fix the computation of short_base_name

 316         (copy_dollar): Now that everything uses obstacks, get rid of the
 317         FILE * parameters.
 318
 319 2000-12-20  Akim Demaille  <akim@epita.fr>
 320
 321         * src/files.c (open_files): Actually the `.output' file is based
 322         on the short_base_name, not base_name.
 323         * tests/suite.at (Checking output file names): Adjust.
 324
 325 2000-12-20  Akim Demaille  <akim@epita.fr>

 328         * src/bison.simple: this.
 329         * src/Makefile.am: Use pkgdata instead of data.
 330
 331 2000-12-20  Akim Demaille  <akim@epita.fr>
 332
 333         * src/files.c (guard_obstack): New.

 351         (stringappend): Be just like strcat but allocate.
 352         (base_names): Eve out from open_files.
 353         Try to simplify the rather hairy computation of base_name and
 354         short_base_name.
 355         (open_files): Use it.
 356         * tests/suite.at (Checking output file names): New test.

 375
 376         Let the handling of the skeleton files be local to the procedures
 377         that use it.
 378
 379         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

 388
 389 2000-12-19  Akim Demaille  <akim@epita.fr>
 390
 391         * src/file.h (BISON_SIMPLE, BISON_HAIRY): Move from here...

 393
 394 2000-12-19  Akim Demaille  <akim@epita.fr>
 395
 396         * src/files.c (open_files): Yipee!  We no longer need all the code
 397         looking for `/tmp' since we have no tmp file.
 398
 399 2000-12-19  Akim Demaille  <akim@epita.fr>
 400
 401         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 402         New macros.
 403         * src/files.c (open_files): Less dependency on MSDOS etc.

 406
 407         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 409         Use it when executing the default @ action.
 410         * src/reader.c (reader_output_yylsp): No longer include
 411         `timestamp' and `text' in the default YYLTYPE.
 412
 413 2000-12-12  Akim Demaille  <akim@epita.fr>
 414
 415         * src/reader.c (copy_definition, parse_union_decl, copy_action)

 426 2000-11-17  Akim Demaille  <akim@epita.fr>
 427
 428         * lib/obstack.h: Formatting changes.
 429         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 430         prevents type checking.
 431         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 432         cast the value to (void *): assigning a `foo *' to a `void *'
 433         variable is valid.
 434         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 435         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 436         append characters.

 451
 452         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

 470
 471 2000-11-07  Akim Demaille  <akim@epita.fr>
 472
 473         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
 474         Merge in a single CPP if/else.
 475
 476 2000-11-07  Akim Demaille  <akim@epita.fr>

 479         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
 480         argument `data' for consistency with the prototypes.
 481         Qualify it `const'.
 482         (obstack_copy, obstack_copy0): Rename the second argument as
 483         `address' for consistency.  Qualify it `const'.
 484         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 485         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 493         Adjust dependencies.
 494
 495 2000-11-03  Akim Demaille  <akim@epita.fr>
 496
 497         For some reason, this was not applied.
 498
 499         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 508
 509         Don't use `atexit'.
 510
 511         * src/files.c (obstack_save): New function.
 512         (done): Rename as...
 513         (output_files): this.
 514         Use `obstack_save'.
 515         * src/main.c (main): Don't use `atexit' to register `done', since
 516         it no longer has to remove tmp files, just call `output_files'
 517         when there are no errors.
 518
 519 2000-11-02  Akim Demaille  <akim@epita.fr>

 564

 587
 588         * src/reader.c (copy_comment2): Expect the input stream to be on
 589         the `/' which is suspected to open a comment, instead of being
 590         called after `//' or `/*' was read.
 591         (copy_comment, copy_definition, parse_union_decl, copy_action)

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

 633         * src/reader.c (parse_expect_decl): Keep `count' within the size
 634         of `buffer'.
 635         From Neil Booth.
 636
 637 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 638
 639         * bison.s1 (yyparse): Assign the default value
 640         unconditionally, to avoid a GCC warning and make the parser a
 641         tad smaller.
 642
 643 2000-10-02  Akim Demaille  <akim@epita.fr>
 644

 649
 650         * src/derives.c, src/print.c, src/reduce.c: To ease the
 651         translation, move some `\n' out of the translated strings.
 652
 653 2000-10-02  Akim Demaille  <akim@epita.fr>
 654
 655         The location tracking mechanism is precious for parse error
 656         messages.  Nevertheless, it is enabled only when `@n' is used in
 657         the grammar, which is a different issue (you can use it in error
 658         message, but not in the grammar per se).  Therefore, there should
 659         be another means to enable it.
 660
 661         * src/getargs.c (getargs): Support `--locations'.
 662         (usage): Report it.
 663         * src/getargs.h (locationsflag): Export it.
 664         * src/lex.c (percent_table): Support `%locations'.
 665         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 666         with `locationsflag'.
 667         * doc/bison.texinfo: Document `--locations' and `%locations'.
 668         Sort the options.
 669         * tests/calc.m4: Test it.
 670
 671         For regularity of the names, replace each
 672         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 673         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 674         In addition replace each `flag' with `_flag'.
 675
 676 2000-10-02  Akim Demaille  <akim@epita.fr>
 677
 678         Also test parse error messages, including with YYERROR_VERBOSE.
 679
 680         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 681         associative).
 682         Use it to check the computations.
 683         Use it to check `nonassoc' is honored.
 684         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 685         `--yyerror-verbose'.
 686         (_AT_CHECK_CALC): Adjust to this option.
 687         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 688
 689 2000-10-02  Akim Demaille  <akim@epita.fr>
 690
 691         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 692         the latter demonstrates a flaw in the handling of non debugging
 693         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 694         was used in order to simplify:
 695
 696         #if YYDEBUG
 697         if (yydebug)
 698         {
 699         ...
 700         }
 701         #endif
 702
 703         into
 704
 705         if (yydebug)
 706         {
 707         ...
 708         }
 709
 710         unfortunately this leads to a CPP conflict when
 711         `--name-prefix=foo' is used since it produces `#define yydebug
 712         foodebug'.
 713
 714         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 715         (YYDPRINTF): New macro.
 716         Spread its use.
 717         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 718         the bison options.
 719         Also test `--verbose', `--defines' and `--name-prefix'.
 720
 721 2000-10-02  Akim Demaille  <akim@epita.fr>
 722
 723         Improve the readability of the produced parsers.
 724
 725         * src/bison.s1: Formatting changes.
 726         Improve the comment related to the `$' mark.
 727         (yydefault): Don't fall through to `yyresume': `goto' there.
 728         * src/output.c (output_parser): When the `$' is met, skip the end
 729         of its line.
 730         New variable, `number_of_dollar_signs', to check there's exactly
 731         one `$' in the parser skeleton.
 732
 733 2000-10-02  Akim Demaille  <akim@epita.fr>
 734
 735         * lib/xstrdup.c: New file, from the fileutils.
 736         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 737         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 738         instead of strlen + xmalloc + strcpy.
 739         * src/symtab.c (copys): Remove, use xstrdup instead.
 740
 741 2000-10-02  Akim Demaille  <akim@epita.fr>
 742
 743         * src/gram.h (associativity): New enum type which replaces the
 744         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 745         `right_assoc', `left_assoc' and `non_assoc'.
 746         Adjust all dependencies.
 747         * src/reader.c: Formatting changes.
 748         (LTYPESTR): Don't define it, use it as a literal in

 762         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 763         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 764         difficult and introduced a lot of core dump.  It turns out that
 765         Bison used an implementation of `xmalloc' based on `calloc', and
 766         at various places it does depend upon the initialization to 0.  I
 767         have not tried to isolate the pertinent places, and all the former
 768         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 769         someone should address this issue.
 770
 771         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 772         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 869
 870 2000-10-02  Akim Demaille  <akim@epita.fr>
 871
 872         `user_toknums' is output as a `short[]' in `output.c', while it is
 873         defined as a `int[]' in `reader.c'.  For consistency with the
 874         other output tables, `user_toknums' is now defined as a table of
 875         shorts.

 918         * src/system.h: Define PARAMS.
 919         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 920         purpose of config.h.  system.h must not try to fix wrong
 921         definitions in config.h.

1126         * src/reader.c (copy_comment): New function, factored out from:
1127         (copy_action): Use it.  Removed now unused `match', `ended',
1128         `cplus_comment'.

1134         (copy_action): Use it.
1135         (copy_guard): Likewise.
1136
1137 2000-03-17  Akim Demaille  <akim@epita.fr>
1138
1139         Change the handling of @s so that they behave exactly like $s.
1140         There is now a pseudo variable @$ (readble and writable), location
1141         of the lhs of the rule (by default ranging from the location of
1142         the first symbol of the rhs, to the location of the last symbol,
1143         or, if the rhs is empty, YYLLOC).
1144
1145         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1146         yyval.
1147         (yyparse): When providing a default semantic action, provide a
1148         default location action.
1149         (after the $): No longer change `*YYLSP', just stack YYLOC the
1150         same way you stack YYVAL.
1151         * src/reader.c (read_declarations): Use warns.
1152         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1153         (copy_action, case '@'): Likewise.
1154         Use a standard error message, to save useless work from
1155         translators.
1156
1157 2000-03-17  Akim Demaille  <akim@epita.fr>
1158
1159         * src/bison.s1: Formatting and cosmetics changes.

1176
1177         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1178         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1179         One `#if YYDEBUG' remains, since it uses variables which are
1180         defined only if `YYDEBUG != 0'.
1181
1182 2000-03-16  Akim Demaille  <akim@epita.fr>

1206         handled via src/Makefile.am.

1208         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
1209         autoheader.

1214         the proper line number and file name.
1215         (DEFS): Propagate the location of bison library files and of the
1216         locale files.
1217         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1218         builddir.
1219         * acinclude.m4: Remove, replaced by the directory m4.
1220         * m4/Makefile.am (EXTRA_DIST): New variable.
1221         * m4/gettext.m4: New file, from the fileutils.

1898         (literalchar); new function to deal with reading \ escapes.
1899         (lex): Use literalchar.
1900         (lex): Implemented "..." tokens.
1901         (literalchar, lex, parse_percent_token): Made tokenbuffer
1902         always contain the token.  This includes growing the token
1903         buffer while reading an integer.

1907         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1908         major changes to files.c.
1909         (lex) Retain in the incoming stream a character following
1910         an incorrect '/'.
