Patch tries to improve the vectorization of stores. Originally, we just check the type and the base pointer of the store. Patch adds some extra checks to avoid non-profitable vectorization cases. It includes analysis of the scalar values to be stored and triggers the vectorization attempt only if the scalar values have same/alt opcode and are from same basic block, i.e. we don't end up immediately with the gather node, which is not profitable. This also improves compile time by filtering out non-profitable cases. Part of D57059. Differential Revision: https://reviews.llvm.org/D104122 |
