[hjl@gnu-6 i386]$ cat x.c
/* { dg-do run } */
/* { dg-options "-O2 -msse2" } */

#include <emmintrin.h>

int
test (__m128d s1, __m128d s2)
{
  return _mm_comieq_sd (s1, s2);
}
[hjl@gnu-6 i386]$ ./usr/gcc-4.4/bin/gcc -S -O2 x.c
[hjl@gnu-6 i386]$ cat x.s
        .file   "x.c"
        .text
        .p2align 4,,15
.globl test
        .type   test, @function
test:
.LFB518:
        xorl    %eax, %eax
        ucomisd %xmm1, %xmm0
        sete    %al
        ret

It should be "comisd %xmm1, %xmm0".
