On an FX-57, EKOPath is close to icc for SPECint2000: http://www.spec.org/osg/cpu2000/results/res2005q2/cpu2000-20050613-04264.html http://www.spec.org/osg/cpu2000/results/res2005q2/cpu2000-20050613-04262.html icc on WinXP SPECint2000 = 1970 pathcc on Linux SPECint2000 = 1929 Do you have a SPECint2000 breakdown for gcc tree-ssa on Linux? The dev's summit mentions SPECint2000 results, but I didn't find what I was looking for. http://www.gccsummit.org/2005/2005-GCC-Summit-Proceedings.pdf -- Regards, Marc
