Adjust all dependencies.

comment associated with the table.
Adjust dependencies.
(output_gram): Use it.
(output_rule_data): Nicer output layout for YYTNAME.
the `/' which is suspected to open a comment, instead of being
called after `//' or `/*' was read.
(copy_comment, copy_definition, parse_union_decl, copy_action)
(copy_guard): Adjust.
`bison -v' segfaults.
Reported by Piotr Gackiewicz, and fixed by Neil Booth.
* tests/regression.m4: New file.
Include the core of the sample provided by Piotr Gackiewicz.
* src/reader.c (parse_token_decl): Diagnose bad cases, and proceed
properly.
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'.
* 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.
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'.
* 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.
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'.
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

Adjust dependencies.

(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.
Propagate its use.
* src/print.c: Formatting and ordering changes.
(verbose, terse): Replace with...

Adjust dependencies.

other output tables, `user_toknums' is now defined as a table of

* 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.

(output_base, output_table, output_check): Use it.

No longer use `register'.

Propagate its inclusion in files explicitly prototyping functions

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