2000-10-02  Paul Eggert  <eggert@twinsun.com>

	* 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  <akim@epita.fr>

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

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

	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
	`sunknown', `stoken and `snterm'.

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

	* 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/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.

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

	* src/LR0.h: New file.
	Propagate its use.

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

	Propagate its use.

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

	* 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.

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

	Factor the short table outputs.

	* src/output.c (output_short_table): New function.
	* src/output.c (output_gram, output_stos, output_rule_data)
	(output_base, output_table, output_check):  Use it.

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

	order to get rid of the `static' prototypes.

	* src/reader.c (reader_output_yylsp):
	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.
	(skip_to_char, read_declarations, copy_definition)
	(parse_token_decl, parse_start_decl, parse_type_decl)

	an invalid character.  Do not abort.
	(read_declarations, copy_guard, copy_action): Use
	printable_version to avoid unprintable characters in printed output.
	(parse_expect_decl): Error if argument to %expect exceeds 10 digits.
	(parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
	Allow the type of a non-terminal can be given
	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.

	Added THONG and NOOP for alias processing.
	Added SETOPT for the new code that allows setting options with %flags.

	(literalchar); new function to deal with reading \ escapes.
	(lex): Use literalchar.

	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.
	(percent_table):  Added %thong declarations.

	* src/gram.h: Comment changes.

	* src/files.c (openfiles, open_extra_files, done):
	 Add faction flag
	and actfile file.  Handle noparserflag.  Both for -n switch.
