This doesn't seem right. The breaks https://github.com/llvm/llvm-project/pull/113281. I can see your commit https://github.com/llvm/llvm-project/pull/114293/commits/ec6f646e905c16a161487fea34c7dea09635c150 which tries to address it. The patch suggests that the FMV feature sve2-aes now means sve-aes. @andrewcarlotti do you agree?
