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.) -- Joseph S. Myers jos...@codesourcery.com
