--- Comment #43 from Peter Bergner <bergner at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #40) > The question is what the code size differences would be with those changes > (i.e. how often does it help not to have *movsi_compare0 make RA decisions > worse vs. how often we actually have those two instructions separated by > other insns). How does *movsi_compare0 make RA decisions worse other than the issue of p116 not being assigned r0 above, which my patch attached above fixes?
