It doesn't seem a good idea to me for a host-side GCC file to use the FE_* names for the target's FE_* values; you'd run into problems if that file ever ends up including the host's <fenv.h>, directly or indirectly, on any host. The same comment applies to the AArch64 patch as well.
Instead I suggest names such as ARM_FE_* that won't conflict with the host's system headers. -- Joseph S. Myers jos...@codesourcery.com
