Although the REP MOVSB implementations of memmove, memcpy and mempcpy aren't used by the current processors, this patch adds Prefer_FSRM check in ifunc-memmove.h so that they can be used in the future. * sysdeps/x86/cpu-features.h (bit_arch_Prefer_FSRM): New. (index_arch_Prefer_FSRM): Likewise. * sysdeps/x86/cpu-tunables.c (TUNABLE_CALLBACK (set_hwcaps)): Also check Prefer_FSRM. * sysdeps/x86_64/multiarch/ifunc-memmove.h (IFUNC_SELECTOR): Also return OPTIMIZE (erms) for Prefer_FSRM. |
