--- Comment #5 from wbrana <wbrana at gmail dot com> 2013-03-08 14:17:52 UTC --- weird results in comment 4 were caused by unexpected Gentoo patches and/or broken GIT I made own build which doesn't contain any Gentoo patches and still can reproduce 9% slow down caused by 196263 When I run reduced test there is only 1% slow down. Reduced test case has similar difference on my PC as in comment 2. I'm using -m64.
