<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Wei Wang (apolloww) <details> <summary>Changes</summary> When creating a new UsingType, the underlying type may change if it is a declaration. This creates an inconsistency between the type searched and type created. Move the update before search so that we always use the same type for search and creation. --- Full diff: https://github.com/llvm/llvm-project/pull/79182.diff 1 Files Affected: - (modified) clang/lib/AST/ASTContext.cpp (+7-6) ``````````diff diff --git a/clang/lib/AST/ASTContext.cpp b/clang/lib/AST/ASTContext.cpp index 5eb7aa3664569dd..d312ef61fb15d4a 100644 --- a/clang/lib/AST/ASTContext.cpp +++ b/clang/lib/AST/ASTContext.cpp @@ -4672,12 +4672,6 @@ QualType ASTContext::getTypedefType(const TypedefNameDecl *Decl, QualType ASTContext::getUsingType(const UsingShadowDecl *Found, QualType Underlying) const { llvm::FoldingSetNodeID ID; - UsingType::Profile(ID, Found, Underlying); - - void *InsertPos = nullptr; - if (UsingType *T = UsingTypes.FindNodeOrInsertPos(ID, InsertPos)) - return QualType(T, 0); - const Type *TypeForDecl = cast<TypeDecl>(Found->getTargetDecl())->getTypeForDecl(); @@ -4687,6 +4681,13 @@ QualType ASTContext::getUsingType(const UsingShadowDecl *Found, if (Underlying.getTypePtr() == TypeForDecl) Underlying = QualType(); + UsingType::Profile(ID, Found, Underlying); + + void *InsertPos = nullptr; + if (UsingType *T = UsingTypes.FindNodeOrInsertPos(ID, InsertPos)) { + return QualType(T, 0); + } + void *Mem = Allocate(UsingType::totalSizeToAlloc<QualType>(!Underlying.isNull()), alignof(UsingType)); `````````` </details> https://github.com/llvm/llvm-project/pull/79182 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
