Created an attachment (id=6961)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=6961&action=view)
Preprocessed file that causes the problem.
I took the proprocessed file and removed any unneeded declarations that came in
from emmintrin.h.

Confirmed a regression from 3.3.3 but fixed already on the mainline.

The failure has nothing to do with GCSE, here's a short example to
demonstrate this. Just compile with "gcc -msse2 -O" to see the crash :-(
=======================================================
typedef int __v4si __attribute__ ((mode (V4SI)));
typedef int __v16qi __attribute__ ((mode (V16QI)));
void foo(int* p)
{
int i;
for ( i=0; i<2; ++i )
{
__v16qi v0, v1=(__v16qi)__builtin_ia32_setzero128();
v0 = __builtin_ia32_punpckhbw128(v0, v1);
__builtin_ia32_stored (p, (__v4si)v0);
}
}
=======================================================
The bug was fixed on mainline by Paolo Bonzini's patch
http://gcc.gnu.org/ml/gcc-cvs/2004-07/msg00949.html
It should probably be applied to the 3.4 branch as well,
although I did not try that yet.

I just applied the patch from Paolo Bonzini to a fresh 3.4.1-release tree and it
fixes this bug.
