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?
