We should also test -O0. This code:
extern __inline __m128i __attribute__((__gnu_inline__, __always_inline__,
__artificial__))
_mm_movpi64_epi64 (__m64 __A)
{
return _mm_set_epi64 ((__m64)0LL, __A);
}
extern __inline __m128i __attribute__((__gnu_inline__, __always_inline__,
__artificial__))
_mm_move_epi64 (__m128i __A)
{
return _mm_set_epi64 ((__m64)0LL, _mm_movepi64_pi64 (__A));
}
Why do we use _mm_movepi64_pi64 at all? _mm_movepi64_pi64 is an MMX
intrinsic. It isn't necessary here.
