It looks like "/Qvec-" what I was mostly looking for (had been trying "/vec-").
For intrinsics, I'd hope something like "_m128i a = _mm_load_si128(b);" gets expanded into normal instructions (in this case, multiple loads into a regular register) instead of SSE ones (movdqa into an xmm).
The following pragma is new feature request:
#pragma vector never
We will discuss this win the internal team. If many customers are looking for this them we may cosider implementing this in the Intel compiler.
