Yes, that's appropriate for tests of roundeven optimization for constant 
arguments.

When you get onto testing roundevenf128 (to cover various cases with 
113-bit precision), you'll need to make those tests appropriately 
conditional on _Float128 support being available - either use "#ifdef 
__FLT128_MAX__" within the test, or have a separate test for those cases 
and use

/* { dg-add-options float128 } */
/* { dg-require-effective-target float128 } */

in that test.  ({ dg-add-options float128 } allows _Float128 tests to be 
run in configurations that only support _Float128 with some command-line 
options.)
