----------------
Please add back the missing newline


================
Comment at: clang/test/SemaCXX/constant-expression-cxx2a.cpp:252
   // ... but in the complete object, the same is not true, so the runtime fails.
-  static_assert(dynamic_cast<const A*>(static_cast<const C2*>(&g)) == nullptr);
+  static_assert(dynamic_cast<const A*>(static_cast<const C2*>(&g)) == nullptr); // expected-warning {{comparison of address of 'g' equal to a null pointer is always false}}
 
----------------
I don't believe we should be emitting a diagnostic for this case. The `static_assert` passes. CC @aaron.ballman
