So to provide ifunc variant for copysign only adds complexity for powerpc and powerpc64 and it not required for powerpc64le. This patch removes both powerpc32 and powerpc64 ifunc variants and consolidates the powerpc implementation on sysdeps/powerpc/fpu/s_copysign{f}.c using compiler builtins. Checked on powerpc-linux-gnu (built without --with-cpu, with --with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch), powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+ and --disable-multi-arch). * sysdeps/powerpc/fpu/s_copysign.c: New file. * sysdeps/powerpc/fpu/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc32/fpu/s_copysign.S: Remove file. * sysdeps/powerpc/powerpc32/fpu/s_copysignf.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/Makefile (sysdep_routines, libm-sysdep_routines): Remove s_copysign-power6 and s_copysign-ppc32. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign-power6.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign-ppc32.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_copysign.S: Likewise. * sysdeps/powerpc/powerpc32/power6/fpu/s_copysignf.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile (sysdeps_calls): Remove s_copysign-power6 s_copysign-ppc64. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign-power6.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysignf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_copysign.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_copysignf.S: Likewise. * sysdeps/powerpc/powerpc64/power6/fpu/s_copysign.S: Likewise. * sysdeps/powerpc/powerpc64/power6/fpu/s_copysignf.S: Likewise. --- sysdeps/powerpc/fpu/s_copysign.c | 32 +++++++++++ sysdeps/powerpc/fpu/s_copysignf.c | 28 ++++++++++ sysdeps/powerpc/powerpc32/fpu/s_copysign.S | 53 ------------------- sysdeps/powerpc/powerpc32/fpu/s_copysignf.S | 1 - .../powerpc32/power4/fpu/multiarch/Makefile | 6 +-- .../power4/fpu/multiarch/s_copysign-power6.S | 33 ------------ .../power4/fpu/multiarch/s_copysign-ppc32.S | 34 ------------ .../power4/fpu/multiarch/s_copysign.c | 45 ---------------- .../power4/fpu/multiarch/s_copysignf.c | 34 ------------ .../powerpc/powerpc32/power6/fpu/s_copysign.S | 49 ----------------- .../powerpc32/power6/fpu/s_copysignf.S | 1 - .../powerpc/powerpc64/fpu/multiarch/Makefile | 3 +- .../fpu/multiarch/s_copysign-power6.S | 32 ----------- .../fpu/multiarch/s_copysign-ppc64.S | 34 ------------ .../powerpc64/fpu/multiarch/s_copysign.c | 45 ---------------- .../powerpc64/fpu/multiarch/s_copysignf.c | 34 ------------ sysdeps/powerpc/powerpc64/fpu/s_copysign.S | 53 ------------------- sysdeps/powerpc/powerpc64/fpu/s_copysignf.S | 1 - .../powerpc/powerpc64/power6/fpu/s_copysign.S | 49 ----------------- .../powerpc64/power6/fpu/s_copysignf.S | 1 - 20 files changed, 64 insertions(+), 504 deletions(-) create mode 100644 sysdeps/powerpc/fpu/s_copysign.c create mode 100644 sysdeps/powerpc/fpu/s_copysignf.c delete mode 100644 sysdeps/powerpc/powerpc32/fpu/s_copysign.S delete mode 100644 sysdeps/powerpc/powerpc32/fpu/s_copysignf.S delete mode 100644 sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign-power6.S delete mode 100644 sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign-ppc32.S delete mode 100644 sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysign.c delete mode 100644 sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_copysignf.c delete mode 100644 sysdeps/powerpc/powerpc32/power6/fpu/s_copysign.S delete mode 100644 sysdeps/powerpc/powerpc32/power6/fpu/s_copysignf.S delete mode 100644 sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign-power6.S delete mode 100644 sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign-ppc64.S delete mode 100644 sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysign.c delete mode 100644 sysdeps/powerpc/powerpc64/fpu/multiarch/s_copysignf.c delete mode 100644 sysdeps/powerpc/powerpc64/fpu/s_copysign.S delete mode 100644 sysdeps/powerpc/powerpc64/fpu/s_copysignf.S delete mode 100644 sysdeps/powerpc/powerpc64/power6/fpu/s_copysign.S delete mode 100644 sysdeps/powerpc/powerpc64/power6/fpu/s_copysignf.S -- 2.17.1 Reviewed-by: Gabriel F.
