I was told crafty has a lot of 64bits arithmetic, so the -m32 numbers for crafty should be an indication of possible regressions in that area. And those numbers look OK to me. If I can find some time, I'll try another benchmark suite to see the effects of CSE path following are significant enough to still be worth its cost. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19721
