The glibc implementation of iseqsig relies on ordered comparison operators raising the "invalid" exception for quiet NaN operands, with a workaround on platforms where a GCC bug means that exception is not raised. For x86, that bug has now been fixed for GCC 8, so this patch disables the workaround in that case. If and when the corresponding bugs for powerpc and s390 are fixed, the headers for those platforms should of course be updated similarly. Tested for x86_64 and x86, including with GCC mainline. Note that other failures appear with GCC mainline because of spurious use of ordered comparison instructions for unordered operations <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82692>. * sysdeps/x86/fpu/fix-fp-int-compare-invalid.h (FIX_COMPARE_INVALID): Define to 0 if [__GNUC_PREREQ (8, 0)]. |
