Julia equivalent of C compiler intrinsics?

What should I do instead?

Use it?

Just to be more clear, I’m replying to,

@kristoffer.carlsson

What is annoying is that there is not a one to one correspondence with LLVM intrinsics and the intrinsics one write in C.

Actually, it is possible just to use the intrinsic even for _mm_add_sd (it is just that clang doesnt use it).

I’m just saying that if there’s a way to do it in julia code, don’t look for intrinsics, and when there’s a way to do it with generic intrinsics, don’t look for backend specific intrinsics. This is the right way to do things and also give the compiler the best input for optimization. I’m not saying that you shouldn’t use any backend intrinsics or other intrinsics, just that they shouldn’t be what you specifically look for.
