en Copyright 2015 Java http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Index/using_if_exists.cpp#089b6efe [Index] Remove reference to `UnresolvedUsingIfExists`Assuming `ns::foo` doesn't exist, given:```using ns::foo __attribute__((using_if_exists));```The AST will look something like:UsingDecl UsingShadowDecl UnresolvedUsingIfExistsDeclThus we end up adding a reference to `UnresolvedUsingIfExistsDecl` whenprocessing `UsingDecl`, but never add the decl itself. In this case thedecl is really the `UsingDecl` anyway though (which we do output), so itmakes more sense to just remove the extra reference.Differential Revision: https://reviews.llvm.org/D124288 List of files: /llvm-project-15.0.7/clang/test/Index/using_if_exists.cpp Fri, 22 Apr 2022 18:36:00 +0000 Ben Barham <ben_barham@apple.com>
