 190
 191 2001-02-21  Akim Demaille  <akim@epita.fr>
 192
 193         * src/reader.c (gensym): `gensym_count' is your own.
 194         Use a static buf to create the symbol name, as token_buffer is no
 195         longer a buffer.

 198
 199         * src/conflicts.c (conflict_report): Be sure not to append to res
 200         between two calls, which could happen if both first sprintf were

 203 2001-02-08  Akim Demaille  <akim@epita.fr>
 204

 206         New, from fileutils 4.0.37.
 207         * configure.in: Require Autoconf 2.49c.  I took some time before
 208         making this decision.  This is the only way out for portability
 209         issues in Bison, it would mean way too much duplicate effort to
 210         import in Bison features implemented in 2.49c since 2.13.
 211         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 212

 218 2001-01-19  Akim Demaille  <akim@epita.fr>
 219
 220         Get rid of the ad hoc handling of token_buffer in the scanner: use
 221         the obstacks.
 222
 223         * src/lex.c (token_obstack): New.
 224         (init_lex): Initialize it.  No longer call...
 225         (grow_token_buffer): this.  Remove it.
 226         Adjust all the places which used it to use the obstack.
 227
 228 2001-01-19  Akim Demaille  <akim@epita.fr>
 229
 230         * src/lex.h: Rename all the tokens:
 231         s/\bENDFILE\b/tok_eof/g;
 232         s/\bIDENTIFIER\b/tok_identifier/g;
 233         etc.
 234         Let them be enums, not #define, to ease debugging.
 235         Adjust all the code.
 236
 237 2001-01-18  Akim Demaille  <akim@epita.fr>
 238
 239         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 240         * src/lex.c (maxtoken, grow_token_buffer): Static.
 241
 242 2001-01-18  Akim Demaille  <akim@epita.fr>
 243
 244         Since we now use obstacks, more % directives can be enabled.
 245
 246         * src/lex.c (percent_table): Also accept `%yacc',
 247         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 248         `%debug'.
 249         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 250         instead of returning a token.
 251         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 252         * src/reader.c (read_declarations): Adjust.
 253         * src/files.c (open_files): Don't call `compute_base_names', don't
 254         compute `attrsfile' since they depend upon data which might be
 255         *in* the input file now.
 256         (output_files): Do it here.
 257         * src/output.c (output_headers): Document the fact that this patch
 258         introduces a guaranteed SEGV for semantic parsers.

 270         * src/system.h (obstack_grow_string): Rename as...
 271         (obstack_sgrow): this.  Be ready to work with non literals.
 272         (obstack_fgrow4): New.
 273
 274 2000-12-20  Akim Demaille  <akim@epita.fr>
 275
 276         * src/files.c (open_files): Fix the computation of short_base_name

 280
 281         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 282         (copy_dollar): Now that everything uses obstacks, get rid of the
 283         FILE * parameters.
 284
 285 2000-12-20  Akim Demaille  <akim@epita.fr>
 286
 287         * src/files.c (open_files): Actually the `.output' file is based
 288         on the short_base_name, not base_name.
 289         * tests/suite.at (Checking output file names): Adjust.
 290
 291 2000-12-20  Akim Demaille  <akim@epita.fr>

 294         * src/bison.simple: this.
 295         * src/Makefile.am: Use pkgdata instead of data.
 296
 297 2000-12-20  Akim Demaille  <akim@epita.fr>
 298
 299         * src/files.c (guard_obstack): New.

 317         (stringappend): Be just like strcat but allocate.
 318         (base_names): Eve out from open_files.
 319         Try to simplify the rather hairy computation of base_name and
 320         short_base_name.
 321         (open_files): Use it.
 322         * tests/suite.at (Checking output file names): New test.

 338         Suggested by Hans Aberg.
 339
 340 2000-12-19  Akim Demaille  <akim@epita.fr>
 341
 342         Let the handling of the skeleton files be local to the procedures
 343         that use it.
 344
 345         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 346         longer static.
 347         (fparser, open_extra_files): Remove.

 361

 376         * src/reader.c (reader_output_yylsp): No longer include
 377         `timestamp' and `text' in the default YYLTYPE.

 393
 394         * lib/obstack.h: Formatting changes.
 395         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 396         prevents type checking.
 397         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 398         cast the value to (void *): assigning a `foo *' to a `void *'
 399         variable is valid.
 400         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

 446         argument `data' for consistency with the prototypes.
 447         Qualify it `const'.
 448         (obstack_copy, obstack_copy0): Rename the second argument as
 449         `address' for consistency.  Qualify it `const'.
 450         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 451         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 463         For some reason, this was not applied.
 464
 465         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 478         (done): Rename as...
 479         (output_files): this.
 480         Use `obstack_save'.
 481         * src/main.c (main): Don't use `atexit' to register `done', since
 482         it no longer has to remove tmp files, just call `output_files'
 483         when there are no errors.

 590         Reported by Piotr Gackiewicz, and fixed by Neil Booth.
 591
 592         * tests/regression.m4: New file.

 601         From Neil Booth.
 602
 603 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 604
 605         * bison.s1 (yyparse): Assign the default value
 606         unconditionally, to avoid a GCC warning and make the parser a
 607         tad smaller.
 608
 609 2000-10-02  Akim Demaille  <akim@epita.fr>
 610

 615
 616         * src/derives.c, src/print.c, src/reduce.c: To ease the

 618
 619 2000-10-02  Akim Demaille  <akim@epita.fr>
 620
 621         The location tracking mechanism is precious for parse error
 622         messages.  Nevertheless, it is enabled only when `@n' is used in
 623         the grammar, which is a different issue (you can use it in error
 624         message, but not in the grammar per se).  Therefore, there should
 625         be another means to enable it.
 626
 627         * src/getargs.c (getargs): Support `--locations'.
 628         (usage): Report it.
 629         * src/getargs.h (locationsflag): Export it.
 630         * src/lex.c (percent_table): Support `%locations'.
 631         * src/reader.c (yylsp_needed): Remove this variable, now replaced
 632         with `locationsflag'.
 633         * doc/bison.texinfo: Document `--locations' and `%locations'.
 634         Sort the options.
 635         * tests/calc.m4: Test it.
 636
 637         For regularity of the names, replace each
 638         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 639         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 640         In addition replace each `flag' with `_flag'.
 641
 642 2000-10-02  Akim Demaille  <akim@epita.fr>
 643
 644         Also test parse error messages, including with YYERROR_VERBOSE.
 645
 646         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 647         associative).
 648         Use it to check the computations.
 649         Use it to check `nonassoc' is honored.
 650         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 651         `--yyerror-verbose'.
 652         (_AT_CHECK_CALC): Adjust to this option.
 653         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 654
 655 2000-10-02  Akim Demaille  <akim@epita.fr>
 656
 657         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 658         the latter demonstrates a flaw in the handling of non debugging
 659         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 660         was used in order to simplify:
 661
 662         #if YYDEBUG
 663         if (yydebug)
 664         {
 665         ...
 666         }
 667         #endif
 668
 669         into
 670
 671         if (yydebug)
 672         {
 673         ...
 674         }
 675
 676         unfortunately this leads to a CPP conflict when
 677         `--name-prefix=foo' is used since it produces `#define yydebug
 678         foodebug'.
 679
 680         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 681         (YYDPRINTF): New macro.
 682         Spread its use.
 683         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 684         the bison options.
 685         Also test `--verbose', `--defines' and `--name-prefix'.
 686
 687 2000-10-02  Akim Demaille  <akim@epita.fr>
 688
 689         Improve the readability of the produced parsers.
 690
 691         * src/bison.s1: Formatting changes.
 692         Improve the comment related to the `$' mark.
 693         (yydefault): Don't fall through to `yyresume': `goto' there.
 694         * src/output.c (output_parser): When the `$' is met, skip the end
 695         of its line.
 696         New variable, `number_of_dollar_signs', to check there's exactly
 697         one `$' in the parser skeleton.
 698
 699 2000-10-02  Akim Demaille  <akim@epita.fr>
 700
 701         * lib/xstrdup.c: New file, from the fileutils.
 702         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
 703         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
 704         instead of strlen + xmalloc + strcpy.
 705         * src/symtab.c (copys): Remove, use xstrdup instead.
 706
 707 2000-10-02  Akim Demaille  <akim@epita.fr>
 708
 709         * src/gram.h (associativity): New enum type which replaces the
 710         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 711         `right_assoc', `left_assoc' and `non_assoc'.
 712         Adjust all dependencies.
 713         * src/reader.c: Formatting changes.
 714         (LTYPESTR): Don't define it, use it as a literal in
 715         `reader_output_yylsp'.
 716         * src/symtab.h (symbol_class): New enum type which replaces the
 717         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 718         `sunknown', `stoken and `snterm'.
 719
 720 2000-10-02  Akim Demaille  <akim@epita.fr>
 721
 722         * src/getargs.c (fixed_outfiles): Rename as...
 723         (yaccflag): for consistency and accuracy.
 724         Adjust dependencies.
 725
 726 2000-10-02  Akim Demaille  <akim@epita.fr>
 727
 728         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 729         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 730         difficult and introduced a lot of core dump.  It turns out that
 731         Bison used an implementation of `xmalloc' based on `calloc', and
 732         at various places it does depend upon the initialization to 0.  I
 733         have not tried to isolate the pertinent places, and all the former
 734         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 735         someone should address this issue.
 736
 737         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 738         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 739         files.
 740         Adjust dependencies.
 741         * src/warshall.h: New file.
 742         Propagate.
 743
 744 2000-10-02  Akim Demaille  <akim@epita.fr>
 745
 746         Various anti-`extern in *.c' changes.
 747

 837
 838         `user_toknums' is output as a `short[]' in `output.c', while it is
 839         defined as a `int[]' in `reader.c'.  For consistency with the
 840         other output tables, `user_toknums' is now defined as a table of
 841         shorts.
 842
 843         * src/reader.c (user_toknums): Be a short table instead of an int
 844         table.

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

 859         Propagate its inclusion in files explicitly prototyping functions
 860         from output.c.

 882         inclusion.
 883         Don't define PARAMS.
 884         * src/system.h: Define PARAMS.
 885         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 886         purpose of config.h.  system.h must not try to fix wrong
 887         definitions in config.h.

1106         There is now a pseudo variable @$ (readble and writable), location
1107         of the lhs of the rule (by default ranging from the location of
1108         the first symbol of the rhs, to the location of the last symbol,
1109         or, if the rhs is empty, YYLLOC).

1117         * src/reader.c (read_declarations): Use warns.
1118         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

1120         Use a standard error message, to save useless work from
1121         translators.

1143         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1144         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

1146         defined only if `YYDEBUG != 0'.

1182         locale files.
1183         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1184         builddir.
1185         * acinclude.m4: Remove, replaced by the directory m4.
1186         * m4/Makefile.am (EXTRA_DIST): New variable.
