If `__builtin_hypotf` works without `math.h`, that is also good for us. But I need more help from people famliar to llvm/clang about what kind of approach we can take to make that work. Maybe we need to wait for https://github.com/llvm/llvm-project/pull/207135#discussion_r3586028267 ?
Or better to use lib/Analysis/TargetLibraryInfo.cpp as suggeted in https://github.com/llvm/llvm-project/pull/207135#discussion_r3580229128 ?
