* tests/Makefile.am (DISTCLEANFILES): Add package.m4.
* tests/calc.at (_AT_DATA_CALC_Y): #undef malloc so that we don't
need xmalloc.c in calc.y.
From Pascal Bart.
* src/getargs.c: Die on `-r'/`--raw'.
* src/lex.c (parse_percent_token): Die on `%raw'.
* src/reader.c (output_token_defines): Suppress call to `raw_flag'.
* tests/calc.at: Suppress test with option `--raw'.
* src/lex.c (percent_table): Also accept `%yacc',
`%fixed_output_files', `%defines', `%no_parser', `%verbose', and
`%debug'.
Handle the actions for `%semantic_parser' and `%pure_parser' here,
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
compute `attrsfile' since they depend upon data which might be
*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.
(stringappend): Be just like strcat but allocate.
(base_names): Eve out from open_files.
Try to simplify the rather hairy computation of base_name and
short_base_name.
(open_files): Use it.
* tests/suite.at (Checking output file names): New test.
`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'.
