> 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).

In Opteron, there was a path from FP to the GP registers, but not the other way
around.  That path was eventually made symmetric in Barcelona only.
