------- Comment #2 from pinskia at gcc dot gnu dot org 2006-08-22 00:24 ------- -mno-ieee-fp is specificially documented as that so that part is not a bug for sure. -funsafe-math-optimizations is already mentioned as a different bug. So only builtin_isunordered without optimizations with -ffinite-math is a problem.
