Richard Henderson <rth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rth at gcc dot gnu.org --- Comment #3 from Richard Henderson <rth at gcc dot gnu.org> 2011-08-02 00:11:34 UTC --- It would certainly be quite a lot of work, but this sort of thing *is* handled by pass_compare_elim_after_reload. That requires exposing the flags register as a CCmode quantity. C.f. the mn10300 port.
