<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang-modules Author: None (smanna12) <details> <summary>Changes</summary> This patch addresses a use-after-move issue, reported by static analyzer tool, by clearing the `PotentiallyInterestingDecls` deque after it has been moved to `MaybeInterestingDecls`. The fix ensures that the subsequent assert statement correctly checks for an empty state, preventing any undefined behavior in ASTReader::PassInterestingDeclsToConsumer(). --- Full diff: https://github.com/llvm/llvm-project/pull/97221.diff 1 Files Affected: - (modified) clang/lib/Serialization/ASTReaderDecl.cpp (+1) ``````````diff diff --git a/clang/lib/Serialization/ASTReaderDecl.cpp b/clang/lib/Serialization/ASTReaderDecl.cpp index 6afb18f932e72..cf3737c5a501d 100644 --- a/clang/lib/Serialization/ASTReaderDecl.cpp +++ b/clang/lib/Serialization/ASTReaderDecl.cpp @@ -4215,6 +4215,7 @@ void ASTReader::PassInterestingDeclsToConsumer() { }; std::deque<Decl *> MaybeInterestingDecls = std::move(PotentiallyInterestingDecls); + PotentiallyInterestingDecls.clear(); assert(PotentiallyInterestingDecls.empty()); while (!MaybeInterestingDecls.empty()) { Decl *D = MaybeInterestingDecls.front(); `````````` </details> https://github.com/llvm/llvm-project/pull/97221 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
