--- Comment #9 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- I'm not comfortable with the results of the patch. Overall I see a slight improvement for SPECint CPU2006 and a slightly larger degradation for SPECfp CPU2006. But there are some individual slowdowns that are unacceptable: 435.gromacs: -8.7% 436.cactusADM: -3.0% On the other hand: 403.gcc: +4.6% All other results within +/- 2%. I'm going to hold off on this until I can investigate the 435.gromacs slowdown.
