o Pass the modes to GET-FP-OPERANDS compiler/ppc/float.lisp: o If the destination register is the same as one of the source registers, an overflow or underflow exception will have replaced the source register with the result. In that case, replace the source value with NIL to indicate we don't know. (We could recompute the source from the result, but there would be a round-off error.)
