Neat. Question: On Github it's stated that implicit conversions
aren't supported, with this example:
__m128i b = _mm_set1_epi32(42);
__m128 a = b; // NO, only works in LDC
Couldn't this be solved through something like this:
struct __m128 {
float4 value;
alias value this;
void opAssign(__m128i rhs) {
value = cast(float4)rhs.value;
}
}
