Yes, that's prevent us taking any extensions from `-target-cpu`, so always pass `-target-feature` and `-tune-cpu` only. > The code in riscv::getRISCVArch prioritizes -march over -mcpu for > architecture extensions for setting -target-features. > > But the backend still applies extensions from -target-cpu via the tablegen > features from RISCV.td. > > So its not even a "priority", we end up with a union. Damm, you are right, that...even worth than I thought before, let me update the summary.
