The entire SH3E / SH4 simulator in sim/sh already uses native floating point, so making just these two instructions use sim-fpu would be pointless. Converting the entire simulator would of course be possible, but I don't see any pressing need to do this now. We have far more urgent issues with SH5 support in gcc and gdb that we should address first.
