powerpc: Refactor powerpc64 lround/lroundf/llround/llroundf
This patches consolidates all the powerpc {l}lround{f} implementations on the generic sysdeps/powerpc/fpu/s_{l}lround{f}.c. The IFUNC support is also moved only to powerpc64 only, since for powerpc64le generic implementation resulting in optimized code. 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/powerpc64/be/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_llround-power8, s_llround-power6x, s_llround-power5+, s_llround-ppc64, and s_llroundf-ppc64. (CFLAGS-s_llround-power8.c, CFLAGS-s_llround-power6x.c, CFLAGS-s_llround-power5+.c): New rule. * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llround-power5+.c: New file. * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llround-power6x.c: Likewise. * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llround-power8.c: Likewise. * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llround-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llroundf-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c: Move to ... * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llround.c: ... here. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llroundf.c: Move to ... * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_llroundf.c: ... here. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_lround.c: Move to ... * sysdeps/powerpc/powerpc64/be/fpu/multiarch/s_lround.c: ... here. * sysdeps/powerpc/powerpc64/fpu/Makefile [$(subdir) == math] (CFLAGS-s_llround.c): New rule. * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile (libm-sysdep_routines): Remove s_llround-* objects. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround-power5+.S: Remove file. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround-power6x.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround-power8.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_llroundf-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_llround.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_llroundf.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_lround.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_lroundf.S: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_llround.c: New file. * sysdeps/powerpc/powerpc64/fpu/s_llroundf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_lround.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/s_lroundf.c: Likewise. * sysdeps/powerpc/powerpc64/power5+/fpu/s_llround.S: Likewise. * sysdeps/powerpc/powerpc64/power5+/fpu/s_llroundf.S: Likewise. * sysdeps/powerpc/powerpc64/power6x/fpu/s_llround.S: Likewise. * sysdeps/powerpc/powerpc64/power6x/fpu/s_llroundf.S: Likewise. * sysdeps/powerpc/powerpc64/power8/fpu/s_llround.S: Likewise. * sysdeps/powerpc/powerpc64/power8/fpu/s_llroundf.S: Likewise.
