> @RKSimon I didn't add `isTriviallyVectorizable` for these because it broke a number of tests in the RISCV backend. `isTriviallyVectorizable` is exposed across all backends and I think what we would want is something that could be opt in per backend. https://github.com/llvm/llvm-project/blob/main/llvm/test/Transforms/SLPVectorizer/RISCV/math-function.ll#L488

This no longer appears to be an issue.
