I think this misses a crucial point as to why it exists. Perhaps something like: "Returns the cost of a vector instruction based on the assumption that it'll be later transformed (by ReplaceWithVecLib) into a call to a platform specific vector math function. Instructions unsupported by ReplaceWithVecLib will return InstructionCost::getInvalid()." https://github.com/llvm/llvm-project/pull/82488 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
