Have you already had an RFC regarding this change? If so, please add a link here. I bet there are a reasonable number of people who are dependent on vectorizer's interleave behavior is hooked up to the unroll flag. I support the direction as being the right thing to do, but we better give a good warning signal so that the affected people will scope the work. Do we already have a clang level interleave control flag? Else, those who are using unroll flag to control interleaving have to use -mllvm -interleave-loops= to get back to the original behavior......
