* powerpc: Use faster means to access FPSCR when possible in some casesPaul A. Clarke2019-06-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using 'mffs' instruction to read the Floating Point Status Control Register (FPSCR) can force a processor flush in some cases, with undesirable performance impact. If the values of the bits in the FPSCR which force the flush are not needed, an instruction that is new to POWER9 (ISA version 3.0), 'mffsl' can be used instead. Cases included: get_rounding_mode, fegetround, fegetmode, fegetexcept. * sysdeps/powerpc/bits/fenvinline.h (__fegetround): Use __fegetround_ISA300() or __fegetround_ISA2() as appropriate. (__fegetround_ISA300) New. (__fegetround_ISA2) New. * sysdeps/powerpc/fpu_control.h (IS_ISA300): New. (_FPU_MFFS): Move implementation... (_FPU_GETCW): Here. (_FPU_MFFSL): Move implementation.... (_FPU_GET_RC_ISA300): Here. New. (_FPU_GET_RC): Use _FPU_GET_RC_ISA300() or _FPU_GETCW() as appropriate. * sysdeps/powerpc/fpu/fenv_libc.h (fegetenv_status_ISA300): New. (fegetenv_status): New. * sysdeps/powerpc/fpu/fegetmode.c (fegetmode): Use fegetenv_status() instead of fegetenv_register(). * sysdeps/powerpc/fpu/fegetexcept.c (__fegetexcept): Likewise.
