...a vector compare for a block that will not go away after vectorization (which is the case if there is a store in it). The LoopVectorizer seems to have this information available. Is it possible to easily use it in this case somehow? Or is it more convenient to add a tti hook to complement the EnableCondStoresVectorization option, perhaps? /Jonas
