Looks like your code does not call sincos directly. sin and cos calls on the same input seem to get optimized into sincos, so I'm not sure if ffinite-math-only can detect that. Also, the patch also changes an installed header, so you need to somehow include that during your compilation. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
