Question on SSE intrinsics

[piotrekg2 via Digitalmars-d-learn]

Hi,
I'm trying to port some of my c++ code which uses sse2 
instructions into D. The code calls the following intrinsics:

- _mm256_loadu_si256
- _mm256_movemask_epi8

Do they have any equivalent intrinsics in D?

I'm compiling my c++ code using gcc.

Thanks,
Piotr
