Do anyone know how to bypass it so that it won't be used? man gcc. as for the sse fp math... it (from memory) makes gcc use the sse instruction set to do floating point math operations. this is likely a bad thing as it 1. means using the "mmx unit" and swapping out of fp mode and thus you have a cycle hit with an emms coming back in - as the fp ops are short and not all over this isn't much worth it. i suspect there is some conversion rounding cumulative error. but as i dont have an amd64 i cant tell you much more than what i suspect. :) -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) [EMAIL PROTECTED] 裸好多 [EMAIL PROTECTED] Tokyo, Japan (東京 日本) ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ enlightenment-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/enlightenment-users
