--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> ---
Does profile feedback (so we have an idea on the loop count) make any
difference? It seems clear that for a loop that in practice just copies one
long, having to arrange the arguments, make a function call, test for
alignment, etc, is a lot of overhead. What to do about it though...
