Summary

0013372: gccxml cannot parse <limits> under GCC 4.7.1

Description

An attempt to parse a header which includes <limits> under GCC 4.7.1 gives the following problem:

------------------------------------------------------------------------
/mnt/disk1/products/gcc/v4_7_1/Linux64bit+2.6-2.12/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.7.1/../../../../include/c++/4.7.1/limits:1405: error: '__int128' was not declared in this scope
/mnt/disk1/products/gcc/v4_7_1/Linux64bit+2.6-2.12/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.7.1/../../../../include/c++/4.7.1/limits:1405: error: template argument 1 is invalid
/mnt/disk1/products/gcc/v4_7_1/Linux64bit+2.6-2.12/bin/../lib/gcc/x86_64-unknown-linux-gnu/4.7.1/../../../../include/c++/4.7.1/limits:1479: error: template argument 1 is invalid
------------------------------------------------------------------------

Steps To Reproduce

Make a file gccxml_test.h containing:
------------------------------------------------------------------------
#include <limits>
struct MyClass {
int fred;
};
------------------------------------------------------------------------
Attempt to parse with:
gccxml gccxml_test.h

Additional Information

Error can be made to go away by defining __STRICT_ANSI__, but not sure if this causes other problems.

Verified with HEAD downloaded 2012/07/02, compiled with GCC 4.7.1.

gccxml lacks support for gcc 4.7

Notes
(0030128) Brad King (manager) 2012-07-26 10:36	We simply need to disable __int128 in the libstdc++ configuration by overriding bits/c++config.h as follows: $ cat GCC_XML/Support/GCC/4.7/bits/c++config.h #include_next <bits/c++config.h> /* GCC 4.2 parser does not support __int128 */ #undef _GLIBCXX_USE_INT128 /cvsroot/GCC_XML/gccxml/GCC_XML/Support/GCC/4.7/bits/c++config.h,v <-- c++config.h initial revision: 1.1
