> Could you elaborate on why? The CFG can contain sub expressions as individual CFG statements. Later parent expressions can again appear as independent CFGStmt. It is not guaranteed that all subexpressions of all expr types appear as CFGStmt. So we recursively visit each CFGStmt and skip already visited Stmt which might have appeared before in CFG. https://github.com/llvm/llvm-project/pull/153661 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
