<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Vlad Serebrennikov (Endilll) <details> <summary>Changes</summary> This patch adds a test for [CWG794](https://cplusplus.github.io/CWG/issues/794.html), which is an NB comment closed as NAD. Author was asked to bring a paper to Evolution, which never happened. So we test for the absence of base-derived conversion in pointer-to-member conversion. --- Full diff: https://github.com/llvm/llvm-project/pull/121660.diff 2 Files Affected: - (modified) clang/test/CXX/drs/cwg7xx.cpp (+12) - (modified) clang/www/cxx_dr_status.html (+1-1) ``````````diff diff --git a/clang/test/CXX/drs/cwg7xx.cpp b/clang/test/CXX/drs/cwg7xx.cpp index 507eb8fb714350..842d172d379005 100644 --- a/clang/test/CXX/drs/cwg7xx.cpp +++ b/clang/test/CXX/drs/cwg7xx.cpp @@ -337,3 +337,15 @@ template <typename...
