It's definitely wrong to have this sort of Arm-specific conditional in architecture-independent tests. Tests requiring floating-point exceptions support should have an appropriate dg-require-effective-target; if that dg-require-effective-target wrongly passes in certain configurations, fix it (or e.g. add a new check_effective_target_fenv_exceptions_double to verify that exceptions work for double, as opposed to the present check_effective_target_fenv_exceptions which checks whether exceptions work for float, and then adjust tests requiring exceptions for double to use the new effective-target). -- Joseph S.
