 230 2001-02-21  Akim Demaille  <akim@epita.fr>
 231
 232         * src/reader.c (gensym): `gensym_count' is your own.
 233         Use a static buf to create the symbol name, as token_buffer is no

 237
 238         * src/conflicts.c (conflict_report): Be sure not to append to res

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

 260         the obstacks.
 261
 262         * src/lex.c (token_obstack): New.
 263         (init_lex): Initialize it.  No longer call...
 264         (grow_token_buffer): this.  Remove it.
 265         Adjust all the places which used it to use the obstack.
 266
 267 2001-01-19  Akim Demaille  <akim@epita.fr>
 268
 269         * src/lex.h: Rename all the tokens:
 270         s/\bENDFILE\b/tok_eof/g;
 271         s/\bIDENTIFIER\b/tok_identifier/g;
 272         etc.
 273         Let them be enums, not #define, to ease debugging.
 274         Adjust all the code.
 275
 276 2001-01-18  Akim Demaille  <akim@epita.fr>
 277
 278         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 279         * src/lex.c (maxtoken, grow_token_buffer): Static.
 280
 281 2001-01-18  Akim Demaille  <akim@epita.fr>
 282
 283         Since we now use obstacks, more % directives can be enabled.
 284
 285         * src/lex.c (percent_table): Also accept `%yacc',
 286         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 287         `%debug'.
 288         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 289         instead of returning a token.
 290         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 291         * src/reader.c (read_declarations): Adjust.
 292         * src/files.c (open_files): Don't call `compute_base_names', don't
 293         compute `attrsfile' since they depend upon data which might be
 294         *in* the input file now.
 295         (output_files): Do it here.
 296         * src/output.c (output_headers): Document the fact that this patch
 297         introduces a guaranteed SEGV for semantic parsers.
 298         * doc/bison.texinfo: Document them.

 309         * src/system.h (obstack_grow_string): Rename as...
 310         (obstack_sgrow): this.  Be ready to work with non literals.
 311         (obstack_fgrow4): New.
 312
 313 2000-12-20  Akim Demaille  <akim@epita.fr>
 314
 315         * src/files.c (open_files): Fix the computation of short_base_name

 320         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 321         (copy_dollar): Now that everything uses obstacks, get rid of the
 322         FILE * parameters.
 323
 324 2000-12-20  Akim Demaille  <akim@epita.fr>
 325
 326         * src/files.c (open_files): Actually the `.output' file is based
 327         on the short_base_name, not base_name.
 328         * tests/suite.at (Checking output file names): Adjust.
 329
 330 2000-12-20  Akim Demaille  <akim@epita.fr>
 331

 333         * src/bison.simple: this.
 334         * src/Makefile.am: Use pkgdata instead of data.
 335
 336 2000-12-20  Akim Demaille  <akim@epita.fr>
 337
 338         * src/files.c (guard_obstack): New.

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

 380
 381         Let the handling of the skeleton files be local to the procedures
 382         that use it.
 383
 384         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No

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

 399 2000-12-19  Akim Demaille  <akim@epita.fr>
 400
 401         * src/files.c (open_files): Yipee!  We no longer need all the code
 402         looking for `/tmp' since we have no tmp file.
 403
 404 2000-12-19  Akim Demaille  <akim@epita.fr>
 405
 406         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 407         New macros.
 408         * src/files.c (open_files): Less dependency on MSDOS etc.

 411
 412         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 432
 433         * lib/obstack.h: Formatting changes.
 434         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 435         prevents type checking.
 436         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 437         cast the value to (void *): assigning a `foo *' to a `void *'
 438         variable is valid.
 439         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 440         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to
 441         append characters.

 456
 457         * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New

 475
 476 2000-11-07  Akim Demaille  <akim@epita.fr>
 477
 478         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 484         * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
 485         argument `data' for consistency with the prototypes.
 486         Qualify it `const'.
 487         (obstack_copy, obstack_copy0): Rename the second argument as
 488         `address' for consistency.  Qualify it `const'.
 489         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 490         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 498         Adjust dependencies.
 499
 500 2000-11-03  Akim Demaille  <akim@epita.fr>
 501
 502         For some reason, this was not applied.
 503
 504         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

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

 592
 593         * src/reader.c (copy_comment2): Expect the input stream to be on
 594         the `/' which is suspected to open a comment, instead of being
 595         called after `//' or `/*' was read.
 596         (copy_comment, copy_definition, parse_union_decl, copy_action)

 629         Reported by Piotr Gackiewicz, and fixed by Neil Booth.

 638         * src/reader.c (parse_expect_decl): Keep `count' within the size
 639         of `buffer'.
 640         From Neil Booth.
 641
 642 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 643
 644         * bison.s1 (yyparse): Assign the default value
 645         unconditionally, to avoid a GCC warning and make the parser a
 646         tad smaller.
 647
 648 2000-10-02  Akim Demaille  <akim@epita.fr>
 649

 654
 655         * src/derives.c, src/print.c, src/reduce.c: To ease the

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

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

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

 873         output_short_table.
 874
 875 2000-10-02  Akim Demaille  <akim@epita.fr>
 876
 877         `user_toknums' is output as a `short[]' in `output.c', while it is
 878         defined as a `int[]' in `reader.c'.  For consistency with the
 879         other output tables, `user_toknums' is now defined as a table of
 880         shorts.

 883         table.

 898         Propagate its inclusion in files explicitly prototyping functions

 922         Don't define PARAMS.
 923         * src/system.h: Define PARAMS.
 924         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 925         purpose of config.h.  system.h must not try to fix wrong
 926         definitions in config.h.

1131         * src/reader.c (copy_comment): New function, factored out from:
1132         (copy_action): Use it.  Removed now unused `match', `ended',
1133         `cplus_comment'.

1141
1142 2000-03-17  Akim Demaille  <akim@epita.fr>
1143
1144         Change the handling of @s so that they behave exactly like $s.
1145         There is now a pseudo variable @$ (readble and writable), location
1146         of the lhs of the rule (by default ranging from the location of
1147         the first symbol of the rhs, to the location of the last symbol,
1148         or, if the rhs is empty, YYLLOC).
1149
1150         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1151         yyval.
1152         (yyparse): When providing a default semantic action, provide a
1153         default location action.
1154         (after the $): No longer change `*YYLSP', just stack YYLOC the
1155         same way you stack YYVAL.
1156         * src/reader.c (read_declarations): Use warns.
1157         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1158         (copy_action, case '@'): Likewise.
1159         Use a standard error message, to save useless work from
1160         translators.
1161
1162 2000-03-17  Akim Demaille  <akim@epita.fr>
1163
1164         * src/bison.s1: Formatting and cosmetics changes.

1181
1182         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1183         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1184         One `#if YYDEBUG' remains, since it uses variables which are
1185         defined only if `YYDEBUG != 0'.
1186
1187 2000-03-16  Akim Demaille  <akim@epita.fr>

1211         handled via src/Makefile.am.

1213         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
1214         autoheader.

1219         the proper line number and file name.
1220         (DEFS): Propagate the location of bison library files and of the
1221         locale files.
1222         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1223         builddir.
1224         * acinclude.m4: Remove, replaced by the directory m4.
1225         * m4/Makefile.am (EXTRA_DIST): New variable.
1226         * m4/gettext.m4: New file, from the fileutils.

1912         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1913         major changes to files.c.
1914         (lex) Retain in the incoming stream a character following
1915         an incorrect '/'.
