Strangely you jump to some conclusions about optimization of memcpy itself, is it better to check why qsort need that many memcpy at first?
In my profiling, qsort in my test case make lots of memcpy(src, dest, 4), how may cpu cycles can be saved if put effort into optimizing memcpy itself when size of only 4??
