Not quite, `Readers` is a `DenseMap` where the value type is a `PointerUnion`, so we need to cast it to one of the possible types which is `APINotesReader *`. I like the idea of making `CurrentModuleReaders` an array of unique pointers regardless. I'll go ahead and do that. https://github.com/llvm/llvm-project/pull/72389 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
