 287
 288         * src/reader.c (gensym): `gensym_count' is your own.
 289         Use a static buf to create the symbol name, as token_buffer is no

 302         * configure.in: Require Autoconf 2.49c.  I took some time before
 303         making this decision.  This is the only way out for portability
 304         issues in Bison, it would mean way too much duplicate effort to
 305         import in Bison features implemented in 2.49c since 2.13.
 306         AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

 317
 318         * src/lex.c (token_obstack): New.
 319         (init_lex): Initialize it.  No longer call...

 327         s/\bIDENTIFIER\b/tok_identifier/g;
 328         etc.
 329         Let them be enums, not #define, to ease debugging.
 330         Adjust all the code.
 331
 332 2001-01-18  Akim Demaille  <akim@epita.fr>
 333
 334         * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

 336
 337 2001-01-18  Akim Demaille  <akim@epita.fr>
 338
 339         Since we now use obstacks, more % directives can be enabled.
 340
 341         * src/lex.c (percent_table): Also accept `%yacc',
 342         `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
 343         `%debug'.
 344         Handle the actions for `%semantic_parser' and `%pure_parser' here,
 345         instead of returning a token.
 346         * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
 347         * src/reader.c (read_declarations): Adjust.
 348         * src/files.c (open_files): Don't call `compute_base_names', don't
 349         compute `attrsfile' since they depend upon data which might be
 350         *in* the input file now.
 351         (output_files): Do it here.
 352         * src/output.c (output_headers): Document the fact that this patch
 353         introduces a guaranteed SEGV for semantic parsers.

 365         * src/system.h (obstack_grow_string): Rename as...
 366         (obstack_sgrow): this.  Be ready to work with non literals.
 367         (obstack_fgrow4): New.
 368

 413         (base_names): Eve out from open_files.

 417         * tests/suite.at (Checking output file names): New test.

 434
 435 2000-12-19  Akim Demaille  <akim@epita.fr>
 436
 437         Let the handling of the skeleton files be local to the procedures

 456
 457         * src/files.c (open_files): Yipee!  We no longer need all the code

 460 2000-12-19  Akim Demaille  <akim@epita.fr>
 461
 462         * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

 492         (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
 493         cast the value to (void *): assigning a `foo *' to a `void *'

 496         * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

 559

 573         (done): Rename as...
 574         (output_files): this.
 575         Use `obstack_save'.
 576         * src/main.c (main): Don't use `atexit' to register `done', since
 577         it no longer has to remove tmp files, just call `output_files'
 578         when there are no errors.

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

 696         From Neil Booth.
 697
 698 2000-10-02  Paul Eggert  <eggert@twinsun.com>
 699
 700         * bison.s1 (yyparse): Assign the default value
 701         unconditionally, to avoid a GCC warning and make the parser a

 713
 714 2000-10-02  Akim Demaille  <akim@epita.fr>
 715
 716         The location tracking mechanism is precious for parse error
 717         messages.  Nevertheless, it is enabled only when `@n' is used in
 718         the grammar, which is a different issue (you can use it in error
 719         message, but not in the grammar per se).  Therefore, there should
 720         be another means to enable it.
 721
 722         * src/getargs.c (getargs): Support `--locations'.

 730         * tests/calc.m4: Test it.
 731
 732         For regularity of the names, replace each
 733         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
 734         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
 735         In addition replace each `flag' with `_flag'.
 736
 737 2000-10-02  Akim Demaille  <akim@epita.fr>
 738
 739         Also test parse error messages, including with YYERROR_VERBOSE.
 740
 741         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
 742         associative).
 743         Use it to check the computations.
 744         Use it to check `nonassoc' is honored.
 745         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
 746         `--yyerror-verbose'.
 747         (_AT_CHECK_CALC): Adjust to this option.
 748         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
 749
 750 2000-10-02  Akim Demaille  <akim@epita.fr>

 752         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
 753         the latter demonstrates a flaw in the handling of non debugging
 754         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
 755         was used in order to simplify:
 756
 757         #if YYDEBUG
 758         if (yydebug)
 759         {
 760         ...
 761         }
 762         #endif
 763
 764         into
 765
 766         if (yydebug)
 767         {
 768         ...
 769         }
 770
 771         unfortunately this leads to a CPP conflict when
 772         `--name-prefix=foo' is used since it produces `#define yydebug
 773         foodebug'.
 774
 775         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
 776         (YYDPRINTF): New macro.
 777         Spread its use.
 778         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
 779         the bison options.
 780         Also test `--verbose', `--defines' and `--name-prefix'.

 788         (yydefault): Don't fall through to `yyresume': `goto' there.
 789         * src/output.c (output_parser): When the `$' is met, skip the end
 790         of its line.
 791         New variable, `number_of_dollar_signs', to check there's exactly
 792         one `$' in the parser skeleton.

 802 2000-10-02  Akim Demaille  <akim@epita.fr>
 803
 804         * src/gram.h (associativity): New enum type which replaces the
 805         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 806         `right_assoc', `left_assoc' and `non_assoc'.
 807         Adjust all dependencies.
 808         * src/reader.c: Formatting changes.
 809         (LTYPESTR): Don't define it, use it as a literal in

 811         * src/symtab.h (symbol_class): New enum type which replaces the
 812         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 813         `sunknown', `stoken and `snterm'.

 822
 823         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 824         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 825         difficult and introduced a lot of core dump.  It turns out that
 826         Bison used an implementation of `xmalloc' based on `calloc', and
 827         at various places it does depend upon the initialization to 0.  I
 828         have not tried to isolate the pertinent places, and all the former
 829         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 830         someone should address this issue.
 831
 832         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 833         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

 845 2000-10-02  Akim Demaille  <akim@epita.fr>

 927         * src/output.c (token_actions): Introduce a temporary array,
 928         YYDEFACT, that makes it possible for this function to use
 929         output_short_table.
 930
 931 2000-10-02  Akim Demaille  <akim@epita.fr>
 932
 933         `user_toknums' is output as a `short[]' in `output.c', while it is
 934         defined as a `int[]' in `reader.c'.  For consistency with the
 935         other output tables, `user_toknums' is now defined as a table of
 936         shorts.
 937
 938         * src/reader.c (user_toknums): Be a short table instead of an int
 939         table.

 949
 950         * src/output.c (output): Topological sort of the functions, in
 951         order to get rid of the `static' prototypes.
 952         No longer use `register'.
 953         * src/output.h: New file.
 954         Propagate its inclusion in files explicitly prototyping functions
 955         from output.c.

 977         inclusion.
 978         Don't define PARAMS.
 979         * src/system.h: Define PARAMS.
 980         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 981         purpose of config.h.  system.h must not try to fix wrong
 982         definitions in config.h.

1145
1146 2000-03-17  Akim Demaille  <akim@epita.fr>
1147
1148         On syntax errors, report the token on which we choked.

1170         copy_comment.  Removed now unused `match', `ended',
1171         `cplus_comment'.
1172         (copy_comment, copy_string): Moved, to be visible from
1173         copy_definition.

1199
1200         Change the handling of @s so that they behave exactly like $s.
1201         There is now a pseudo variable @$ (readble and writable), location
1202         of the lhs of the rule (by default ranging from the location of
1203         the first symbol of the rhs, to the location of the last symbol,
1204         or, if the rhs is empty, YYLLOC).
1205

1207         yyval.
1208         (yyparse): When providing a default semantic action, provide a
1209         default location action.
1210         (after the $): No longer change `*YYLSP', just stack YYLOC the
1211         same way you stack YYVAL.
1212         * src/reader.c (read_declarations): Use warns.
1213         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
1214         (copy_action, case '@'): Likewise.
1215         Use a standard error message, to save useless work from
1216         translators.

1237
1238         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
1239         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
1240         One `#if YYDEBUG' remains, since it uses variables which are
1241         defined only if `YYDEBUG != 0'.
1242
1243 2000-03-16  Akim Demaille  <akim@epita.fr>

1269         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

1277         locale files.
1278         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
1279         builddir.
1280         * acinclude.m4: Remove, replaced by the directory m4.
1281         * m4/Makefile.am (EXTRA_DIST): New variable.
1282         * m4/gettext.m4: New file, from the fileutils.

1928         (get_type, packsymbols):  Revised most error messages.
1929         Changed `fatal' to `warnxxx' to avoid aborting for error.
1930         Revised and use multiple warnxxx functions to avoid using VARARGS1.

1948         (fatals): Updated to not use VARARGS1.
1949         (printable_version, int_to_string, warn, warni, warns, warnss)
1950         (warnsss): New error reporting functions.  Avoid abort for error.
1951
1952         * src/lex.h:

1966         (parse_percent_token): Added % declarations as another
1967         way to specify the flags -n, -l, and -r.  Also added hooks for
1968         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1969         major changes to files.c.
1970         (lex) Retain in the incoming stream a character following
1971         an incorrect '/'.
1972         (skip_white_space, lex):  Revised most error messages
1973         and changed fatal to warn to avoid aborting.
