Why two files? This could be done like this:

// RUN: clang-cc -Dwant_feature=1 -fobjc-nonfragile-abi %s
// RUN: clang-cc %s

#if defined(want_feature) && !__has_feature(objc_nonfragile_abi)
#error Want nonfragile ABI but do not have it
#elif !defined(want_feature) && __has_feature(objc_nonfragile_abi)
#error Do not want nonfragile ABI but have it
#endif
