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?
