        * tests/calc.at, tests/output.at, tests/regression.at,
        * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

        use abs. path to find config.h.
        * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

        * src/lex.c (parse_percent_token): Replace equal_offset with
        arg_offset.
        arg is const.

2001-11-12  Akim Demaille  <akim@epita.fr>

        * src/reader.c (parse_union_decl): Output yystype/YYSTYPE as we do

        *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.

        cast the value to (void *): assigning a `foo *' to a `void *'

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

        * 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  <akim@epita.fr>

        The location tracking mechanism is precious for parse error
        messages.  Nevertheless, it is enabled only when `@n' 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  <akim@epita.fr>

        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  <akim@epita.fr>

        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  <akim@epita.fr>

        Improve the readability of the produced parsers.

        * src/bison.s1: Formatting changes.
        Improve the comment related to the `$' mark.
        (yydefault): Don't fall through to `yyresume': `goto' there.
        * src/output.c (output_parser): When the `$' 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  <akim@epita.fr>

        * 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  <akim@epita.fr>

        * 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

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

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

        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.

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

        * src/state.h (nstates, final_state, first_state, first_shift)
        (first_reduction): Move their exportation from here...
        * src/LR0.h: to here.
        Adjust dependencies.
        * src/getargs.c (statisticsflag): New variable.
        Add support for `--statistics'.
        Adjust dependencies.

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

        * 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  <akim@epita.fr>

        `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.

        table.

        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).

        New function.
        (readgram): Use `#if 0' around code that accepted %command
        inside grammar rules:  The documentation doesn't allow it,
        and it will fail since the %command processors scan for the next %.
        (parse_token_decl):  Extended the %token
        declaration to allow a multi-character symbol as an alias.
        (parse_thong_decl): New function.
        (read_declarations): Added %thong declarations.
        (read_declarations): Handle NOOP to deal with allowing
        % declarations as another means to specify the flags.
        (readgram): Allow %prec prior to semantics embedded in a rule.

        (get_type, packsymbols):  Revised most error messages.
        Changed `fatal' to `warnxxx' to avoid aborting for error.
        Revised and use multiple warnxxx functions to avoid using VARARGS1.
        (read_declarations): Improve the error message for
        an invalid character.  Do not abort.
        (read_declarations, copy_guard, copy_action): Use
        printable_version to avoid unprintable characters in printed output.

        more than once, as long as all specifications give the same type.

        * src/output.c:
        (output_headers, output_trailers, output, output_gram)
        (output_rule_data): Implement noparserflag variable.

        (warnsss): New error reporting functions.  Avoid abort for error.

        * src/lex.h:
        Added THONG and NOOP for alias processing.
        Added SETOPT for the new code that allows setting options with %flags.

        * src/lex.c:
        Include getopt.h.  Add some extern decls.
        (safegetc): New function to deal with EOF gracefully.
        (literalchar); new function to deal with reading \ escapes.
        (lex): Use literalchar.
        (lex): Implemented "..." tokens.
        (literalchar, lex, parse_percent_token): Made tokenbuffer
        always contain the token.  This includes growing the token
        buffer while reading an integer.
        (parse_percent_token): Replaced if-else statement with percent_table.
        (parse_percent_token): Added % declarations as another
        way to specify the flags -n, -l, and -r.  Also added hooks for
        -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
        major changes to files.c.
        (lex) Retain in the incoming stream a character following
        an incorrect '/'.
        (skip_white_space, lex):  Revised most error messages
        and changed fatal to warn to avoid aborting.
