--- Comment #6 from Segher Boessenkool <segher at gcc dot gnu.org> --- It certainly would be nice to improve this :-) It won't help most code very much -- how often do two-word values happen at all -- but we have to revisit how all this is decided anyway (for prefixed instructions), so now would be a good time :-)
