Bison 1.28c is released |

Gnus/5.0808 (Gnus v5.8.8) XEmacs/21.4 (Artificial Intelligence) |
The following message is a courtesy copy of an article
that has been posted to gnu.utils.bug as well.
This is our release candidate. The sources are frozen, and we expect
1.29 to be released by the end of the month. Yet the development of
the next release has started comprising C++ parser generation.
This beta includes a hidden experimental but stable feature: -g,
--graph outputs the automaton in VCG. An interactive browser may be
found at:
http://rw4.cs.uni-sb.de/users/sander/html/gsvcg1.html
We would like to thank our contributors, especially Hans Aberg, Marc
Autret, Pascal Bart, and Robert Anisko.
Enjoy!

NEWS:
Changes in version 1.28c:
* The Bison manual is now distributed under the terms of the GNU FDL.
* 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',
`%debug', `%source_extension' and `%header_extension'.

(obstack_grow, obstack_grow0): Don't cast WHERE at all: it
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 *'
variable is valid.
(obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

(copy_guard): Adjust.
2000-10-16 Akim Demaille <address@hidden>

of `buffer'.
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>

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.
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 <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.

(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.

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.
Factor the short table outputs.

* src/acconfig.h: Don't protect config.h against multiple
inclusion.
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.
2000-09-20 Akim Demaille <address@hidden>
* src/derives.h: New file.

2000-09-19 Akim Demaille <address@hidden>

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.

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.

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.
