gcc -O2 -mmmx i386-mmx-5.c
GCC fails thus:

i386-mmx-5.c: In function 'main':
i386-mmx-5.c:15: internal compiler error: in simplify_binary_operation, at simplify-rtx.c:2151
Please submit a full bug report,
with preprocessed source if appropriate.

/* { dg-do run { target i?86-*-* x86_64-*-* } } */
/* { dg-options "-O2 -mmmx" } */
#include <mmintrin.h>
#include <stdlib.h>

__m64 global_mask;

main()
{
    __m64 zero = _mm_setzero_si64();
    __m64 mask = _mm_cmpeq_pi8( zero, zero );
    mask = _mm_unpacklo_pi8( mask, zero );
    global_mask = mask;
    exit(0);
