[PATCH] csky: Improve abiv1 mem ops performance with glibc codes

2019-06-28 Thread guoren
From: Guo Ren These codes are copied from glibc/string directory, they are the generic implementation for string operations. We may further optimize them with assembly code in the future. In fact these code isn't tested enough for kernel, but we've tested them on glibc and it seems good. We
