--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- > How is this accomplished internally in A53 and A57? I don't know about A53 and A57 but I can say that for Cavium's Thunder, it does not go through the load/store unit and there is a direct path between the gprs and fps (and the latency for them is low).
