--- Comment #19 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Richard, I still get 2.7 per iteration for GCC 4.9. For mainline and inline limits bumped ad extermum I can not get better than 3.3 (and it is what I get with -O3 -Ofast too). I am not sure if inliner is to blame or it is effect of some other change. Perhaps since you know the code, you may take a look what is causing the difference? I plan to continue by looking into -fwhole-program issue that is still slower (5.2) than normal compilation.
