This was modeled to have a cost of 1, but since we do not have a MUL.2d this is scalarized into vector inserts/extracts and scalar muls. Motivating precommitted test is test/Transforms/SLPVectorizer/AArch64/mul.ll, which we don't want to SLP vectorize. Test Transforms/LoopVectorize/AArch64/extractvalue-no-scalarization-required.ll unfortunately needed changing, but the reason is documented in LoopVectorize.cpp:6855: // The cost of executing VF copies of the scalar instruction. This opcode // is unknown. Assume that it is the same as 'mul'. which I will address next as a follow up of this. Differential Revision: https://reviews.llvm.org/D92208 |
