(+cflags): Add +math-flags so that all of glibc gets compiled with it. Should be closed as fixed once libm-test.inc supports testing underflow exceptions and an appropriate test has been added. -- 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. ^ permalink raw reply [flat|nested] 7+ messages in thread
