Hi all, I am trying out the new loop vectorizer in LLVM 3.2. I wanted to see the effect of the pass in `opt` but I have no success. I used LLVM IR generated from C examples in http://blog.llvm.org/2012/12/new-loop-vectorizer.html#more and pass them to `opt -S -O3 -vectorize-loops example.ll`. However, I do not see vectorized output. What am I doing wrong? Thanks, Siu -------------- next part

...uses it to initialize the backend passes. 3. 'opt' gets the default target triple (like llc). I think that Nick said that he prefers #2.
