That doesn't seem to be expected to work on powerpc targets. It fails on GNU/Linux, it's marked to be skipped on AIX, and a similar test, gcc.dg/torture/pr93133.c, has the execution test xfailed for all of powerpc*-*-*. In this test, the functions that use intrinsics for the compare end up with the same code as the one that uses compare operators, using fcmpu, a floating compare that, unlike fcmpo, does not set the invalid operand exception for quiet NaN. I couldn't find any evidence that the rs6000 backend ever outputs fcmpo. Therefore, I'm adding the same execution xfail marker to this test. This was regstrapped on x86_64-linux-gnu, tested with a cross to a ppc64-vxworks7r2, and I'm now also regstrapping on ppc64-linux-gnu just to be sure.
