* configure.ac (VALGRIND_PREBISON): New.
* tests/Makefile.am (maintainer-check-valgrind): Use it.
* etc/darwin11.4.0.supp: New.
* configure.ac, etc/Makefile.am: Use it.
* configure.ac: Disable Valgrind on Mac OS X.
* README-hacking: Explain why.
* data/c++.m4, data/c.m4 (b4_yylloc_default_define): New.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c: Use it.
* data/glr.cc: Do not define YYLLOC_DEFAULT in the header file,
but in the implementation one.
The following mixture is insane:
#define YYSTYPE_IS_TRIVIAL PREFIX_STYPE_IS_TRIVIAL
#if (defined YYSTYPE_IS_TRIVIAL && YYSTYPE_IS_TRIVIAL)
since, of course YYSTYPE_IS_TRIVIAL is defined. Instead we could
define YYSTYPE_IS_TRIVIAL as PREFIX_STYPE_IS_TRIVIAL only when the
later is defined, but let's avoid stacking CPP on top of M4: rather, use
#if (defined PREFIX_STYPE_IS_TRIVIAL && PREFIX_STYPE_IS_TRIVIAL)
* data/glr.c, data/yacc.c: Use YYSTYPE_IS_TRIVIAL, YYSTYPE_IS_DECLARED,
YYLTYPE_IS_TRIVIAL and YYLTYPE_IS_DECLARED under their api.prefix-renamed
name.
The testsuite in master has shown weird errors for the "Mulitple
Parsers" tests: the caller of p5.parse() received some apparently
random value, while tracing p5.parse() showed that the function was
consistently returning 0.
It happens when mixing several parser headers, some generated without
%debug, others with. In particular the C++ parser was generated with
%debug, i.e., with:
#ifndef YYDEBUG
# define YYDEBUG 1
#endif
and compiled separatedly. Yet, its header was included after the one
of another parser, this time without %debug, i.e., with
#ifndef YYDEBUG
# define YYDEBUG 0
#endif
in its header. As a result, the parser was compiled with YYDEBUG set,
but its header was used without. Since the layout of the objects are
then completely different, boom.
Therefore, do not change the value of YYDEBUG. Rather, use it as a
default value for <API.PREFIX>DEBUG.
* data/c.m4 (b4_YYDEBUG_define): New.
(b4_declare_yydebug): Rename as...
(b4_yydebug_declare): this, for consistency.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c: Use it.
* NEWS: Document it.
This is more consistent with the other packages, and Automake-NG
supports only *.texi.
* doc/bison.texinfo: Rename as...
* doc/bison.texi: this.
* doc/Makefile.am, examples/calc++/Makefile.am: Adjust.
* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
Use a diversion to avoid outputting comments etc.
Removes 17k lines from testsuite (10% of the number of lines).
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Factor.
Use AT_YYERROR_DEFINE.
Therefore, instead of using stdout, use and check stderr.
* tests/glr-regression.at (Uninitialized location when reporting ambiguity):
Use AT_YYERROR_DEFINE.
