I have some code where at some point, after doing SSE3 computations with __m128d-typed values, I need to:
a) store a __m128d value into one of the two halves of a __m256d value (not cast it!)
b) paste two __m128d values side-by-side into a __m256d value
Are there any AVX intrinsics to perform these operations?
Thanks in advance,
