...mits or maximum instr per group etc, so finding all candidate pairs become rather time consuming. So the candidate selection is not compatible with BB vectorizer, and whole bunch of code was removed… Anyways, perhaps interesting parts for integrating to BBVectorizer could be (crude) caching during replaceOutputs to be used when vectorizing phi nodes. There is also some vectorization of getelementpointer instructions, creation vectors of allocas to get better vector memory accesses, some magic about computing addresses of stride memory accesses using vectors, some tweaks to eliminate unneeded shuffle instr...
