Bison 1.28b

[Akim Demaille]

We are finally on the right tracks to release 1.29.  There are still
some documentation issues to handle, we might include some code to
output VCG representation of the automaton, but the core is stable.

The most dangerous change wrt 1.28 is the use of obstacks instead of
temporary files.  I'm afraid this could cause problems on low memory
machines.  Please, test it exhaustively.

Enjoy!

NEWS:
Changes in version 1.28b:

* the input and the output files has automatically a similar extension.

* Russian translation added.

* NLS support updated; should hopefully be less troublesome.

* Added the old Bison reference card.

* Added `--locations' and `%locations'.

* Added `-S' and `--skeleton'.

* `%raw', `-r', `--raw' is disabled.

* Special characters are escaped when output.  This solves the problems
  of the #line lines with path names including backslashes.

* New directives.
  `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
  `%debug'.

        New, from fileutils 4.0.37.
        * configure.in: Require Autoconf 2.49c.  I took some time before

        issues in Bison, it would mean way too much duplicate effort to
        import in Bison features implemented in 2.49c since 2.13.
        AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

2001-02-02  Akim Demaille  <address@hidden>

2001-01-19  Akim Demaille  <address@hidden>

        * src/lex.h: Rename all the tokens:
        s/\bENDFILE\b/tok_eof/g;
        s/\bIDENTIFIER\b/tok_identifier/g;
        etc.
        Let them be enums, not #define, to ease debugging.

        `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

        instead of returning a token.
        * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
        * src/reader.c (read_declarations): Adjust.
        * src/files.c (open_files): Don't call `compute_base_names', don't

        *in* the input file now.
        (output_files): Do it here.
        * src/output.c (output_headers): Document the fact that this patch
        introduces a guaranteed SEGV for semantic parsers.
        * doc/bison.texinfo: Document them.
        * tests/suite.at: Exercise these %options.

2000-12-20  Akim Demaille  <address@hidden>

        (obstack_grow_string): this.
        * src/output.c (output_parser): Recognize `%% actions' instead of

        prevents type checking.
        (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
        cast the value to (void *): assigning a `foo *' to a `void *'

        (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
        `const' their input argument (`data' or `address').
        Adjust the corresponding macros to include `const' in casts.

        Use `obstack_save'.

        From Neil Booth.

2000-10-02  Paul Eggert  <address@hidden>

        * bison.s1 (yyparse): Assign the default value
        unconditionally, to avoid a GCC warning and make the parser a
        tad smaller.

2000-10-02  Akim Demaille  <address@hidden>

        * src/getargs.c (getargs): Don't dump `--help' on unrecognized
        options.

2000-10-02  Akim Demaille  <address@hidden>

        * src/derives.c, src/print.c, src/reduce.c: To ease the
        translation, move some `\n' out of the translated strings.

2000-10-02  Akim Demaille  <address@hidden>

        The location tracking mechanism is precious for parse error
        messages.  Nevertheless, it is enabled only when address@hidden' is 
used in
        the grammar, which is a different issue (you can use it in error
        message, but not in the grammar per se).  Therefore, there should
        be another means to enable it.

        * src/getargs.c (getargs): Support `--locations'.
        (usage): Report it.
        * src/getargs.h (locationsflag): Export it.
        * src/lex.c (percent_table): Support `%locations'.
        * src/reader.c (yylsp_needed): Remove this variable, now replaced
        with `locationsflag'.
        * doc/bison.texinfo: Document `--locations' and `%locations'.
        Sort the options.
        * tests/calc.m4: Test it.

        For regularity of the names, replace each
        (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
        (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
        In addition replace each `flag' with `_flag'.

2000-10-02  Akim Demaille  <address@hidden>

        Also test parse error messages, including with YYERROR_VERBOSE.

        * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
        associative).
        Use it to check the computations.
        Use it to check `nonassoc' is honored.
        (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
        `--yyerror-verbose'.
        (_AT_CHECK_CALC): Adjust to this option.
        (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.

2000-10-02  Akim Demaille  <address@hidden>

        Test also `--verbose', `--defines' and `--name-prefix'.  Testing
        the latter demonstrates a flaw in the handling of non debugging
        parsers introduced by myself on 2000-03-16: `#define yydebug 0'
        was used in order to simplify:

        #if YYDEBUG
        if (yydebug)
        {
        ...
        }
        #endif

        into

        if (yydebug)
        {
        ...
        }

        unfortunately this leads to a CPP conflict when
        `--name-prefix=foo' is used since it produces `#define yydebug
        foodebug'.

        * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
        (YYDPRINTF): New macro.
        Spread its use.
        * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
        the bison options.
        Also test `--verbose', `--defines' and `--name-prefix'.

2000-10-02  Akim Demaille  <address@hidden>

        Improve the readability of the produced parsers.

        * src/bison.s1: Formatting changes.

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

2000-10-02  Akim Demaille  <address@hidden>

        * lib/xstrdup.c: New file, from the fileutils.
        * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
        (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
        instead of strlen + xmalloc + strcpy.
        * src/symtab.c (copys): Remove, use xstrdup instead.

2000-10-02  Akim Demaille  <address@hidden>

        * src/gram.h (associativity): New enum type which replaces the
        former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
        `right_assoc', `left_assoc' and `non_assoc'.
        Adjust all dependencies.
        * src/reader.c: Formatting changes.
        (LTYPESTR): Don't define it, use it as a literal in
        `reader_output_yylsp'.
        * src/symtab.h (symbol_class): New enum type which replaces the
        former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
        `sunknown', `stoken and `snterm'.

2000-10-02  Akim Demaille  <address@hidden>

        * src/getargs.c (fixed_outfiles): Rename as...
        (yaccflag): for consistency and accuracy.
        Adjust dependencies.

2000-10-02  Akim Demaille  <address@hidden>

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

        * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
        * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
        files.

        * src/warshall.h: New file.
        Propagate.

        * src/getargs.c (statisticsflag): New variable.
        Add support for `--statistics'.
        Adjust dependencies.

        Remove a lot of now useless `extern' statements in most files.

2000-10-02  Akim Demaille  <address@hidden>

        * src/output.c (token_actions): Introduce a temporary array,
        YYDEFACT, that makes it possible for this function to use
        output_short_table.

2000-10-02  Akim Demaille  <address@hidden>

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

        * src/reader.c (user_toknums): Be a short table instead of an int
        table.
        Adjust dependencies.

        from output.c.

        purpose of config.h.  system.h must not try to fix wrong
        definitions in config.h.

        (copy_guard): Use it.
        (copy_action): Use it.

2000-03-17  Akim Demaille  <address@hidden>

        Be kind to translators, save some useless translations.

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

2000-03-17  Akim Demaille  <address@hidden>

        * src/reader.c (copy_string): Declare `static inline'.  No
        problems with inline, since it is checked by configure.
        (copy_comment): Likewise.

2000-03-17  Akim Demaille  <address@hidden>

        * src/reader.c (packsymbols): Formatting changes.

2000-03-17  Akim Demaille  <address@hidden>

        * src/reader.c (copy_comment): New function, factored out from:

        `cplus_comment'.
        (copy_guard): Likewise.

2000-03-17  Akim Demaille  <address@hidden>

        * src/reader.c (copy_string): New function, factored out from:
        (copy_action): Use it.
        (copy_guard): Likewise.

2000-03-17  Akim Demaille  <address@hidden>

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

        * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
        yyval.
        (yyparse): When providing a default semantic action, provide a
        default location action.
        (after the $): No longer change `*YYLSP', just stack YYLOC the
        same way you stack YYVAL.
        * src/reader.c (read_declarations): Use warns.
        (copy_guard, case '@'): Also recognize address@hidden', expanded as 
`YYLOC'.
        (copy_action, case '@'): Likewise.
        Use a standard error message, to save useless work from
        translators.

2000-03-17  Akim Demaille  <address@hidden>

        * src/bison.s1: Formatting and cosmetics changes.
        * src/reader.c: Likewise.
        Update the Copyright notice.

2000-03-17  Akim Demaille  <address@hidden>

        * src/bison.s1 (#line): All set to `#line' only, since the
        Makefile now handles them.

2000-03-16  Akim Demaille  <address@hidden>

        * src/output.c (output_rule_data): Output the documentation of
        some of the tables.
        (Copyright notice): Update.
        Formatting changes.

2000-03-16  Akim Demaille  <address@hidden>

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

2000-03-16  Akim Demaille  <address@hidden>

        * src/bison.s1 (yyparse): Reorganize the definitions of the stacks
        and related variables so that the similarities are highlighted.

        (DEFS): Propagate the location of bison library files and of the
        locale files.

        builddir.
        * acinclude.m4: Remove, replaced by the directory m4.
        * m4/Makefile.am (EXTRA_DIST): New variable.
