#include <mmintrin.h>
void
foo (__m64 *p)
{
__m64 m;
m = p[0];
m = _mm_srli_pi16(m, 2);
m = _mm_slli_pi16(m, 8);
p[0] = m;
_mm_empty();
}
ICEs with both -O2 -m32 and -O2 -m64, in GCC 4.0.2, 4.1rc1 as well as trunk.

------- Comment #1 from jakub at gcc dot gnu dot org 2006-02-20 11:01 -------
Obviously with -O2 -m32 -mmmx for 32-bit compiles.
The testcase compiles in GCC 3.2.3 and 3.4.5, so a regression.
