To clarify my previous comment. I'm not suggesting you "must" implement a set of `fp_op->gpr->fpr` combines specific to the sequences you care about. I only used that to illustrate my view of this being a combine rather than a lowering problem. If splitting the operation in two (i.e. in_place_fp_cvt->transfer_to_gpr) is sufficient for your needs (because there are already combines that'll remove transfer_to_gpr) then I'm happy with that.
