I don't know.  Look at the souces.

Some good points.  It isn't clear to me whether this occurs often enough
to be worth the trouble though.  You will probably have to try it and
see.  There are few targets nowadays that can't load a double with a
single instruction, so this addresss arithmetic from the splitter is
going to be rare outside the SH, and this is probably only the early SH
architectures, maybe 1-3?
