Are there any plans to integrate an autovectorizer for SPMD programs into LLVM? For example, there were previous discussions about integrating the whole function vectorizer (WFV) from Ralf Karrenberg into LLVM.

Wouldn't OpenMP account for some of that? At least on a single machine, could you have both parallel and simd optimisations done on the same loop? For MPI solutions, I believe just vectorising the code per architecture would achieve a similar goal.

What other points could be relevant, here?
