The root of the problem is that we save and restore rounding modes in functions that we don't have non-RN modes implemented. This calls feupdateenv (IIRC), which in turn calls feraiseexcept if there was an exception to be raised. The exception mask check in x86_64 was incorrect, causing feraiseexcept to be called all the time. with the fix, it is only called when there actually is an exception. -- 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.
