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

 213
 214 2001-02-21  Akim Demaille  <akim@epita.fr>
 215
 216         * src/reader.c (gensym): `gensym_count' is your own.
 217         Use a static buf to create the symbol name, as token_buffer is no

 221
 222         * src/conflicts.c (conflict_report): Be sure not to append to res
 223         between two calls, which could happen if both first sprintf were

 226 2001-02-08  Akim Demaille  <akim@epita.fr>
 227

 229         New, from fileutils 4.0.37.
 230         * configure.in: Require Autoconf 2.49c.  I took some time before
 231         making this decision.  This is the only way out for portability
 232         issues in Bison, it would mean way too much duplicate effort to
 233         import in Bison features implemented in 2.49c since 2.13.
 234         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
 235

 241 2001-01-19  Akim Demaille  <akim@epita.fr>
 242

 244         the obstacks.
 245
 246         * src/lex.c (token_obstack): New.
 247         (init_lex): Initialize it.  No longer call...
 248         (grow_token_buffer): this.  Remove it.
 249         Adjust all the places which used it to use the obstack.
 250
 251 2001-01-19  Akim Demaille  <akim@epita.fr>
 252
 253         * src/lex.h: Rename all the tokens:
 254         s/\bENDFILE\b/tok_eof/g;
 255         s/\bIDENTIFIER\b/tok_identifier/g;
 256         etc.
 257         Let them be enums, not #define, to ease debugging.
 258         Adjust all the code.
 259
 260 2001-01-18  Akim Demaille  <akim@epita.fr>
 261
 262         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.
 263         * src/lex.c (maxtoken, grow_token_buffer): Static.
 264
 265 2001-01-18  Akim Demaille  <akim@epita.fr>
 266
 267         Since we now use obstacks, more % directives can be enabled.
 268
 269         * src/lex.c (percent_table): Also accept `%yacc',
 270         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 271         `%debug'.
 272         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 273         instead of returning a token.
 274         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 275         * src/reader.c (read_declarations): Adjust.
 276         * src/files.c (open_files): Don't call `compute_base_names', don't
 277         compute `attrsfile' since they depend upon data which might be
 278         *in* the input file now.
 279         (output_files): Do it here.
 280         * src/output.c (output_headers): Document the fact that this patch
 281         introduces a guaranteed SEGV for semantic parsers.
 282         * doc/bison.texinfo: Document them.

 293         * src/system.h (obstack_grow_string): Rename as...
 294         (obstack_sgrow): this.  Be ready to work with non literals.
 295         (obstack_fgrow4): New.
 296
 297 2000-12-20  Akim Demaille  <akim@epita.fr>
 298
 299         * src/files.c (open_files): Fix the computation of short_base_name

 303
 304         * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
 305         (copy_dollar): Now that everything uses obstacks, get rid of the
 306         FILE * parameters.
 307
 308 2000-12-20  Akim Demaille  <akim@epita.fr>
 309
 310         * src/files.c (open_files): Actually the `.output' file is based
 311         on the short_base_name, not base_name.
 312         * tests/suite.at (Checking output file names): Adjust.
 313
 314 2000-12-20  Akim Demaille  <akim@epita.fr>

 317         * src/bison.simple: this.
 318         * src/Makefile.am: Use pkgdata instead of data.
 319
 320 2000-12-20  Akim Demaille  <akim@epita.fr>
 321
 322         * src/files.c (guard_obstack): New.

 340         (stringappend): Be just like strcat but allocate.
 341         (base_names): Eve out from open_files.
 342         Try to simplify the rather hairy computation of base_name and
 343         short_base_name.
 344         (open_files): Use it.
 345         * tests/suite.at (Checking output file names): New test.
 346
 347 2000-12-19  Akim Demaille  <akim@epita.fr>

 359         there are.
 360         * src/Makefile.am (bison.simple): Be a simple copy of bison.s1.
 361         Suggested by Hans Aberg.
 362
 363 2000-12-19  Akim Demaille  <akim@epita.fr>
 364
 365         Let the handling of the skeleton files be local to the procedures
 366         that use it.
 367
 368         * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
 369         longer static.
 370         (fparser, open_extra_files): Remove.

 383 2000-12-19  Akim Demaille  <akim@epita.fr>
 384
 385         * src/files.c (open_files): Yipee!  We no longer need all the code
 386         looking for `/tmp' since we have no tmp file.
 387
 388 2000-12-19  Akim Demaille  <akim@epita.fr>
 389
 390         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):
 391         New macros.
 392         * src/files.c (open_files): Less dependency on MSDOS etc.

 395
 396         * src/bison.s1 (YYLLOC_DEFAULT): New macro.

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

 461
 462         * src/bison.s1 (YYLEX): Use #if instead of #ifdef.

 469         argument `data' for consistency with the prototypes.

 471         (obstack_copy, obstack_copy0): Rename the second argument as
 472         `address' for consistency.  Qualify it `const'.
 473         * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
 474         (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify

 483
 484 2000-11-03  Akim Demaille  <akim@epita.fr>
 485
 486         For some reason, this was not applied.
 487
 488         * src/files.c [VMS]: No longer include `ssdef.h', no longer define

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

 578         the `/' which is suspected to open a comment, instead of being
 579         called after `//' or `/*' was read.

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

 624         From Neil Booth.
 625
 626 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 627
 628         * bison.s1 (yyparse): Assign the default value
 629         unconditionally, to avoid a GCC warning and make the parser a
 630         tad smaller.
 631
 632 2000-10-02  Akim Demaille  <akim@epita.fr>
 633

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

 751         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 752         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 753         difficult and introduced a lot of core dump.  It turns out that
 754         Bison used an implementation of `xmalloc' based on `calloc', and
 755         at various places it does depend upon the initialization to 0.  I
 756         have not tried to isolate the pertinent places, and all the former
 757         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 758         someone should address this issue.
 759
 760         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 761         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 860
 861         `user_toknums' is output as a `short[]' in `output.c', while it is
 862         defined as a `int[]' in `reader.c'.  For consistency with the
 863         other output tables, `user_toknums' is now defined as a table of
 864         shorts.

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

1128         Change the handling of @s so that they behave exactly like $s.
1129         There is now a pseudo variable @$ (readble and writable), location
1130         of the lhs of the rule (by default ranging from the location of
1131         the first symbol of the rhs, to the location of the last symbol,
1132         or, if the rhs is empty, YYLLOC).
1133
1134         * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
1135         yyval.
1136         (yyparse): When providing a default semantic action, provide a
1137         default location action.
1138         (after the $): No longer change `*YYLSP', just stack YYLOC the
1139         same way you stack YYVAL.
1140         * src/reader.c (read_declarations): Use warns.
1141         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1142         (copy_action, case '@'): Likewise.
1143         Use a standard error message, to save useless work from
1144         translators.
1145
1146 2000-03-17  Akim Demaille  <akim@epita.fr>
1147
1148         * src/bison.s1: Formatting and cosmetics changes.

1165
1166         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1167         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1168         One `#if YYDEBUG' remains, since it uses variables which are
1169         defined only if `YYDEBUG != 0'.
1170

1195         handled via src/Makefile.am.

1197         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
1198         autoheader.

1203         the proper line number and file name.
1204         (DEFS): Propagate the location of bison library files and of the
1205         locale files.
1206         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1207         builddir.
1208         * acinclude.m4: Remove, replaced by the directory m4.
1209         * m4/Makefile.am (EXTRA_DIST): New variable.
