   3         * src/vcg_default.h: Use NULL instead of 0 to initialize pointers.
   4         * src/vcg.c (output_node): Fix.
   5         * src/vcg.h: Cleanup.
   6         * src/print_graph.c: Add comments.
   7         (node_output_size): New global variable. Simplify the formatting of
   8         the VCG graph output.
   9         (print_actions): Unused code is now used. It notifies the final state
  10         and no action states in the VCG graph. It also give the reduce actions.
  11         The `shift and goto' edges are red and the `go to state' edges are
  12         blue.
  13         Get the current node name and node_obstack by argument.
  14         (node_obstack): New variable.
  15         (print_state): Manage node_obstack.
  16         (print_core): Use node_obstack given by argument.
  17         A node is not only computed here but in print_actions also.
  18         (print_graph): CPP out useless code instead of commenting it.

 209
 210 2001-02-21  Akim Demaille  <akim@epita.fr>
 211
 212         * src/reader.c (gensym): `gensym_count' is your own.
 213         Use a static buf to create the symbol name, as token_buffer is no

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

 240         the obstacks.
 241
 242         * src/lex.c (token_obstack): New.
 243         (init_lex): Initialize it.  No longer call...
 244         (grow_token_buffer): this.  Remove it.
 245         Adjust all the places which used it to use the obstack.

 248
 249         * src/lex.h: Rename all the tokens:
 250         s/\bENDFILE\b/tok_eof/g;
 251         s/\bIDENTIFIER\b/tok_identifier/g;
 252         etc.
 253         Let them be enums, not #define, to ease debugging.
 254         Adjust all the code.
 255
 256 2001-01-18  Akim Demaille  <akim@epita.fr>
 257
 258         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 259         * src/lex.c (maxtoken, grow_token_buffer): Static.
 260
 261 2001-01-18  Akim Demaille  <akim@epita.fr>
 262
 263         Since we now use obstacks, more % directives can be enabled.
 264
 265         * src/lex.c (percent_table): Also accept `%yacc',
 266         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 267         `%debug'.
 268         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 269         instead of returning a token.
 270         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 271         * src/reader.c (read_declarations): Adjust.
 272         * src/files.c (open_files): Don't call `compute_base_names', don't
 273         compute `attrsfile' since they depend upon data which might be
 274         *in* the input file now.
 275         (output_files): Do it here.
 276         * src/output.c (output_headers): Document the fact that this patch
 277         introduces a guaranteed SEGV for semantic parsers.

 289         * src/system.h (obstack_grow_string): Rename as...
 290         (obstack_sgrow): this.  Be ready to work with non literals.
 291         (obstack_fgrow4): New.
 292
 293 2000-12-20  Akim Demaille  <akim@epita.fr>

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

 300         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 301         (copy_dollar): Now that everything uses obstacks, get rid of the
 302         FILE * parameters.
 303
 304 2000-12-20  Akim Demaille  <akim@epita.fr>
 305
 306         * src/files.c (open_files): Actually the `.output' file is based
 307         on the short_base_name, not base_name.
 308         * tests/suite.at (Checking output file names): Adjust.
 309
 310 2000-12-20  Akim Demaille  <akim@epita.fr>

 313         * src/bison.simple: this.
 314         * src/Makefile.am: Use pkgdata instead of data.
 315
 316 2000-12-20  Akim Demaille  <akim@epita.fr>
 317
 318         * src/files.c (guard_obstack): New.

 336         (stringappend): Be just like strcat but allocate.
 337         (base_names): Eve out from open_files.
 338         Try to simplify the rather hairy computation of base_name and
 339         short_base_name.
 340         (open_files): Use it.
 341         * tests/suite.at (Checking output file names): New test.

 357         Suggested by Hans Aberg.
 358
 359 2000-12-19  Akim Demaille  <akim@epita.fr>
 360
 361         Let the handling of the skeleton files be local to the procedures
 362         that use it.
 363
 364         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 365         longer static.
 366         (fparser, open_extra_files): Remove.

 379 2000-12-19  Akim Demaille  <akim@epita.fr>
 380
 381         * src/files.c (open_files): Yipee!  We no longer need all the code
 382         looking for `/tmp' since we have no tmp file.
 383
 384 2000-12-19  Akim Demaille  <akim@epita.fr>
 385
 386         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 387         New macros.
 388         * src/files.c (open_files): Less dependency on MSDOS etc.

 391
 392         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

 412
 413         * lib/obstack.h: Formatting changes.
 414         (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
 415         prevents type checking.
 416         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 417         cast the value to (void *): assigning a `foo *' to a `void *'
 418         variable is valid.
 419         (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
 420         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

 457
 458         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 467         (obstack_copy, obstack_copy0): Rename the second argument as
 468         `address' for consistency.  Qualify it `const'.
 469         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 470         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 479
 480 2000-11-03  Akim Demaille  <akim@epita.fr>
 481
 482         For some reason, this was not applied.
 483
 484         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

 497         (done): Rename as...
 498         (output_files): this.
 499         Use `obstack_save'.
 500         * src/main.c (main): Don't use `atexit' to register `done', since
 501         it no longer has to remove tmp files, just call `output_files'
 502         when there are no errors.

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

 620         From Neil Booth.
 621
 622 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 623
 624         * bison.s1 (yyparse): Assign the default value
 625         unconditionally, to avoid a GCC warning and make the parser a
 626         tad smaller.
 627
 628 2000-10-02  Akim Demaille  <akim@epita.fr>
 629

 634
 635         * src/derives.c, src/print.c, src/reduce.c: To ease the

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

 747         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 748         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 749         difficult and introduced a lot of core dump.  It turns out that
 750         Bison used an implementation of `xmalloc' based on `calloc', and
 751         at various places it does depend upon the initialization to 0.  I
 752         have not tried to isolate the pertinent places, and all the former
 753         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 754         someone should address this issue.
 755

 856
 857         `user_toknums' is output as a `short[]' in `output.c', while it is
 858         defined as a `int[]' in `reader.c'.  For consistency with the
 859         other output tables, `user_toknums' is now defined as a table of
 860         shorts.

 903         * src/system.h: Define PARAMS.
 904         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

1126         of the lhs of the rule (by default ranging from the location of
1127         the first symbol of the rhs, to the location of the last symbol,
1128         or, if the rhs is empty, YYLLOC).
1129
1130         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1131         yyval.
1132         (yyparse): When providing a default semantic action, provide a
1133         default location action.
1134         (after the $): No longer change `*YYLSP', just stack YYLOC the
1135         same way you stack YYVAL.
1136         * src/reader.c (read_declarations): Use warns.
1137         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1138         (copy_action, case '@'): Likewise.
1139         Use a standard error message, to save useless work from
1140         translators.

1162         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1163         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1164         One `#if YYDEBUG' remains, since it uses variables which are
1165         defined only if `YYDEBUG != 0'.
1166

1199         the proper line number and file name.
1200         (DEFS): Propagate the location of bison library files and of the
1201         locale files.
1202         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1203         builddir.
1204         * acinclude.m4: Remove, replaced by the directory m4.
1205         * m4/Makefile.am (EXTRA_DIST): New variable.

1894         (lex) Retain in the incoming stream a character following
1895         an incorrect '/'.
1896         (skip_white_space, lex):  Revised most error messages
1897         and changed fatal to warn to avoid aborting.
