have complex pointer manipulation going on. This allows us to compile
stuff like this:
__m128i foo(__m128i x){
static const unsigned int c_0[4] = { 0, 0, 0, 0 };
__m128i v_Zero = _mm_loadu_si128((__m128i*)c_0);
x = _mm_unpacklo_epi8(x, v_Zero);
return x;
}
into:
_foo:
xorps %xmm1, %xmm1
punpcklbw %xmm1, %xmm0
