xazax.hun added inline comments.
================
Comment at: clang/include/clang/AST/ASTImporterSharedState.h:43
+ /// Set of the newly created declarations.
+ llvm::DenseSet<Decl *> NewDecls;
+
----------------
ASTImporter already has something like `ImportedFromDecls`. Is that not
sufficient to check if a declaration is new?
Is it possible that we may want the "degree" of the imported definition? I.e.,
how many hops did we do to import it (is it imported as a result of evaluating
an imported call?).
================
Comment at: clang/include/clang/AST/ASTImporterSharedState.h:81
+
+ bool isNewDecl(const Decl *ToD) const { return NewDecls.count(ToD); }
+
----------------
I assume this would only be applicable for definitions, so I wonder whether
`IsNewDefinition()` would be more descriptive. Or maybe `IsImportedDefinition`?
================
Comment at: clang/lib/AST/ASTImporter.cpp:248
Importer.RegisterImportedDecl(FromD, ToD);
+ Importer.SharedState->setNewDecl(ToD);
InitializeImportedDecl(FromD, ToD);
----------------
Should this be part of `Importer.RegisterImportedDecl`?
