(From update of attachment 121262)
I've tested codes in many cases. Among using memcpy, memmove, memmove in reverse destination and for-loop to copy the values, the for-loop shows the worst timelap in any cases. I've tested it under linux x86 and ARM circumstance. There is not much time gap between memcpy and memmove. Sometimes memcpy shows the best but it wasn't always. If I consider the code readability, I think it would be better using memmove only. So as the result, this patch is not bad as I worried. I add the request to commit-queue again.
