Background: ----------- There are two related argument types which can be sent into a diagnostic to display the name of an entity: DeclarationName (ak_declarationname) or NamedDecl* (ak_nameddecl) (there is also ak_identifierinfo for IdentifierInfo*, but we are not concerned with it here). A DeclarationName in a diagnostic will just be streamed to the output, which will directly result in a call to DeclarationName::print. A NamedDecl* in a diagnostic will also ultimately result in a call to DeclarationName::print, but with two customisation points along the way: The first customisation point is NamedDecl::getNameForDiagnostic which is overloaded by FunctionDecl, ClassTemplateSpecializationDecl and VarTemplateSpecializationDecl to print the template arguments, if any. The second customisation point is NamedDecl::printName. By default it just streams the stored DeclarationName into the output but it can be customised to provide a user-friendly name for an entity. It is currently overloaded by DecompositionDecl 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 fix this 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 which demonstrates that the change is appropriate (either with this patch or the next one).
