Limit the MEMSET (setmemsi pattern) and MEMCPY (movmemsi pattern) instructions to 0-511 bytes.
Limit the MEMSET (setmemsi pattern) and MEMCPY (movmemsi pattern)
instructions to 0-511 bytes. There is a hardware limitation on large
MEMSET, MEMCPY operations that the library versions of memset() and
memcpy() deal with.
