Peter Bergner <bergner@us.ibm.com> * 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. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fe_nomask.c: Moved to... * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/fe_nomask.c: ...here. * sysdeps/unix/sysv/linux/powerpc/powerpc64/fe_nomask.c: Moved to... * sysdeps/unix/sysv/linux/powerpc/powerpc64/fpu/fe_nomask.c: ...here. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/fe_mask.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/fpu/fe_mask.c: New file. |
