* sysdeps/powerpc/bits/fenv.h: Declare __fe_mask_env extern.
Define FE_NOMASK_ENV as FE_EANBLED_ENV. Define FE_MASK_ENV.
* sysdeps/powerpc/fpu/Makefile: Add fe_mask to libm-support.
* sysdeps/powerpc/fpu/fe_mask.c: New file.
* sysdeps/powerpc/fpu/fe_nomask.c: Correct comment.
* sysdeps/powerpc/fpu/fedisblxcpt.c (fedisableexcept):
Call __fe_mask_env() if all FP exceptions disabled.
* sysdeps/powerpc/fpu/feholdexcpt.c (feholdexcept): Copy high 32-bits
from old FPSCR to new fenv to propagate DFP rounding modes.
Call __fe_mask_env() if FP exceptions previously enabled.
* sysdeps/powerpc/fpu/fesetenv.c (fesetenv): Change mask to merge
exceptions from env. Use __fe_nomask_env() or __fe_mask_env() when
transitioning from all exceptions disabled to any exception enabled
or visa versa.
* sysdeps/powerpc/fpu/feupdateenv.c (__feupdateenv): Change mask to
merge exceptions from env. Call __fe_nomask_env or __fe_mask_env
when transitioning from all exceptions disabled to any exception
enabled or visa versa.
