I've seen nothing in fpu_helper.c to update the fpscr to FP_FR, that is there is no code with `fpscr |= FP_FR`, is that valid for PowerPC? or it's just because this is hard to implement and then the FP_FR are always not set for fpscr
It is unimplemented, yes. I think that no one has spent the time; I don't think that it should be hard, necessarily.
