gcc.dg/torture/pr91323.c tests that a compare with NaNf doesn't set an exception using builtin compare intrinsics, and that it does when using regular compare operators.
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.
