Currently both power6 and power7 ifunc variant resulting binary are essentially the same and the generic implementation with unrolling loop set to 8 also results in similar performance. Checked on powerpc64-linux-gnu. * sysdeps/powerpc/Makefile [$(subdir) == wcsmbs] (CFLAGS-wcschr.c): New rule. * sysdeps/powerpc/power6/wcschr.c: Remove file. * sysdeps/powerpc/powerpc32/power4/multiarch/wcschr-power6.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcschr-power7.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcschr-ppc32.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcschr.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcschr-power6.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcschr-power7.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcschr-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcschr.c: Likewise. * sysdeps/powerpc/powerpc64/power6/wcschr.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/Makefile [$(subdir) == wcsmbs] (sysdeps_routines): Remove wcschr-power6 and wcschr-power7. (CFLAGS-wcschr-power7.c, CFLAGS-wcschr-power6.c): Remove rule. * sysdeps/powerpc/powerpc64/multiarch/Makefile: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/ifunc-impl-list.c: Remove wcschr optimizations.
