musl/src/string/aarch64, branch v1.2.3 musl - an implementation of the standard library for Linux-based systems add optimized aarch64 memcpy and memset 2020-06-26T21:49:51+00:00 Rich Felker dalias@aerifal.cx 2020-06-26T21:37:21+00:00 fdf8b2ad9c5ae6adf3a91c0043eb898badee46d1 these are based on the ARM optimized-routines repository v20.05 (ef907c7a799a), with macro dependencies flattened out and memmove code removed from memcpy. this change is somewhat unfortunate since having the branch for memmove support in the large n case of memcpy is the performance-optimal and size-optimal way to do both, but it makes memcpy alone (static-linked) about 40% larger and suggests a policy that use of memcpy as memmove is supported. tabs used for alignment have also been replaced with spaces.
