--- Comment #2 from Wilco <wdijkstr at arm dot com> ---
Memcpy shares code with memmove for sizes up to 128 bytes, so it is essenti=
al
to do all loads before any store. Finegrained interleaving of loads/stores
isn't needed on out-of-order cores - all you want to avoid is extremes like
doing 32 loads and then 32 stores.
