LoopVectorizer is aware when a target can replace a scalable frem instruction with a vector library call for a given VF and it returns the relevant cost. Otherwise, it returns an invalid cost (as previously). Add test that check costs on AArch64, when there is no vector library available and when there is (with and without tail-folding). NOTE: Invoking CostModel directly (not through LV) would still return invalid costs. |
