[PATCH] D159083: Clang: Don't warn about unused private fields of types declared maybe_unused

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added a comment.

Thank you for working on this! Mostly looks good, but I did have another test request. Also, please be sure to add a release note for the fix.



================
Comment at: clang/test/SemaCXX/warn-unused-private-field.cpp:291-292
+enum [[maybe_unused]] MaybeUnusedEnum {};
+typedef int MaybeUnusedTypedef [[maybe_unused]];
+class C {
+  MaybeUnusedClass c; // no-warning
----------------
Let's try one more thing:
```
template <typename Ty, typename Uy>
class C2 {
  Ty c; // no-warning
  Uy d; // warning
};

class [[maybe_unused]] Good {};
class Bad {};

C2<Good, Bad> c;
```
