--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Plus if this is just the return case how important is that because maybe we should be inlining this kind of function. Plus this is a memcpy, why not just use the expansion of __builtin_memcpy here (which is tuned for each target better).
