[Bug middle-end/26379] New: ICE on vector shift RTL simplification

[jakub at gcc dot gnu dot org]

#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.
