--- Comment #1 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
The target seems to set flag_finite_math_only.  We are much more aggressive=
 at
folding comparisons involving infinities with this flag.

config/rx/rx.cc:

      /* Alert the user if they are changing the optimization options
         to use IEEE compliant floating point arithmetic with RX FPU insns.=
  */
      if (TARGET_USE_FPU
          && !flag_finite_math_only)
        warning (0, "RX FPU instructions do not support NaNs and infinities=
");
    }

I think this test is invalid for this architecture.  XFAIL?=
