static void* clib_memcpy ( void *  dst, const void *  src, size_t  n  )

inlinestatic

Copy less than 16 bytes

Fast way when copy size doesn't exceed 512 bytes

Make store aligned when copy size exceeds 512 bytes

Copy 256-byte blocks. Use copy block function for better instruction order control, which is important when load is unaligned.

Copy 64-byte blocks. Use copy block function for better instruction order control, which is important when load is unaligned.

Copy whatever left
