Hello, What is the way to set vector width with polly. I used following command for polly vectorization in clang; i don't use opt because it looks clang llvm and opt are same with polly; clang -S -emit-llvm matn.c -march=knl -O3 -mllvm -polly -mllvm -polly-vectorizer=stripmine -o matn_poly.ll is the above command correct? Here getting vector width=16, i want to set it to 64? not know how to do?? Also what is the advantage of vectorization with polly? -------------- next part -------------- An HTML attachment was scrubbed...
