[LLVMdev] LLVM Loop Vectorizer
...ne function pass that sets up processor specific value in all of instructions in a loop vectorized by opt. This pass could look over options to see what is expected by the user and what is set to default etc. for example for newest x86-64 there is an option -mprefer-avx128 for gcc, which helps over 256AVX for several cases. The generic vector types in llvm could be put to use in opt.
