By default it juststreams the stored DeclarationName into the output but it can be customisedto provide a user-friendly name for an entity. It is currently overloaded byDecompositionDecl and MSGuidDecl.What this patch does:---------------------For many diagnostics a DeclarationName is used instead of the NamedDecl*.This bypasses the two customisation points mentioned above. This patches fixthis for diagnostics in Sema.cpp, SemaCast.cpp, SemaChecking.cpp, SemaDecl.cpp,SemaDeclAttr.cpp, SemaDecl.cpp, SemaOverload.cpp and SemaStmt.cpp.I have only modified diagnostics where I could construct a test-case whichdemonstrates that the change is appropriate (either with this patch or the nextone).Reviewed By: erichkeane, aaron.ballmanDifferential Revision: https://reviews.llvm.org/D84656 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/warn-large-by-value-copy.cpp Mon, 27 Jul 2020 22:22:21 +0000 Bruno Ricci <riccibrun@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/warn-large-by-value-copy.cpp#7f21bd74 Don't crash with -Wlarge-by-value-copy and a dependent type.
