--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Alternatively, we could arrange for the saving of %mm0/%mm1 registers (if
TARGET_MMX) not by generic code, but through fxsave (if TARGET_FXSR), or
fnsave;frstor (otherwise), in __builtin_apply do fxrstor or frstor to get back
the %mm0/%mm1 registers if needed and after the call save the %mm0 or %st(0)
with
another fxsave or fnsave;frstor and in __builtin_return restore again with
fxrstor or frstor.
