Hi all,<div><br></div><div>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 <a href="http://blog.llvm.org/2012/12/new-loop-vectorizer.html#more">http://blog.llvm.org/2012/12/new-loop-vectorizer.html#more</a> and pass them to `opt -S -O3 -vectorize-loops example.ll`. However, I do not see vectorized output. What am I doing wrong? </div>
