Hi, This patch xfails a float128 comparison test case on powerpc64 that fails due to a longstanding issue with floating-point compares.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58684 for more information. The case is xfailed when instructions of float128 hardware are generated. When software simulation is used, the case should pass. The patch passed regression test on Power Linux platforms.
