Selfhost LLVM and Clang on ARM

Hi, all

  I am trying to selfhost LLVM and Clanf on ARM. Hopefully
doing this can reveal what version of GCC is broken. But I
have a concern about the following message while building
LLVM and Clang by using clang (selfhost build).

Hi chenwj,



They are now warnings and you should be fine. But ultimately, those
restrictions could be implemented to avoid the warnings.
