If you mean the vectorization code in Polly, yes, there is already had
some discussion on polly-dev list[1], the first step is to eliminate

Yes, Polly only vectorize a loop when it knows something can be vectorized.

Please join the polly-dev[2] list if You are interested in connect the
BBVectorizer with Polly:)
