Thanks for the feedback @AaronBallman ! I’ve added test coverage under `clang/test/AST` covering both basic declarations and macro expansion behavior, and updated the implementation to use `getPresumedLoc()` so it reflects expansion locations correctly. I’ve also added a release note for the new flag.

 For modules/PCH cases, I haven’t added tests yet but happy to follow up with additional coverage there if needed.
