[PATCH] D157114: [clang][ASTImporter] Improve StructuralEquivalence algorithm on repeated friends

[Ding Fei via Phabricator via cfe-commits]

danix800 added a comment.

`CXXRecordDecl::friend_iterator` is actually a reversed iterator. Deduplication with
different iterator direction produces different result. ASTImporter uses forward iterator
so structural equivalence checking should be in consistent with that.
