<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Egor Zhdan (egorzhdan) <details> <summary>Changes</summary> This fixes an issue where overriding `clang::ConstTemplateArgumentVisitor::VisitTemplateArgument` in an implementation visitor class did not have the desired effect: the overload was not invoked when one of the visitor methods (e.g. `VisitDeclarationArgument`) is not implemented, instead it dispatched to `clang::ConstTemplateArgumentVisitor::VisitTemplateArgument` itself and always returned a default-initialized result. This makes `TemplateArgumentVisitor` and `ConstTemplateArgumentVisitor` follow the implicit convention that is followed elsewhere in Clang AST, in `RecursiveASTVisitor` and `TypeVisitor`. --- Full diff: https://github.com/llvm/llvm-project/pull/115336.diff 1 Files Affected: - (modified) clang/include/clang/AST/TemplateArgumentVisitor.h (+2-1) ``````````diff diff --git a/clang/include/clang/AST/TemplateArgumentVisitor.h b/clang/include/clang/AST/TemplateArgumentVisitor.h index cf0d3220158063..923f045a995703 100644 --- a/clang/include/clang/AST/TemplateArgumentVisitor.h +++ b/clang/include/clang/AST/TemplateArgumentVisitor.h @@ -52,7 +52,8 @@ class Base { #define VISIT_METHOD(CATEGORY) \ RetTy Visit##CATEGORY##TemplateArgument(REF(TemplateArgument) TA, \ ParamTys...
