Use generic memset/memcpy/memmove in benchtests
Use the generic C memset/memcpy/memmove in benchtests since comparing against a slow byte-oriented implementation makes no sense. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> 2019-08-29 Wilco Dijkstra <wdijkstr@arm.com> * benchtests/bench-memcpy.c (simple_memcpy): Remove. (generic_memcpy): Include generic C memcpy. * benchtests/bench-memmove.c (simple_memmove): Remove. (generic_memmove): Include generic C memmove. * benchtests/bench-memset.c (simple_memset): Remove. (generic_memset): Include generic C memset. * benchtests/bench-memset-large.c (simple_memset): Remove. (generic_memset): Include generic C memset. * benchtests/bench-memset-walk.c (simple_memset): Remove. (generic_memset): Include generic C memset. * string/memcpy.c (MEMCPY): Add defines to enable redirection. * string/memset.c (MEMSET): Likewise. * sysdeps/x86_64/memcopy.h: Remove empty file.
