URL: https://github.com/llvm/llvm-project/commit/3321c2d72ab7757dbdd38bdd99a76d89293dac8a DIFF: https://github.com/llvm/llvm-project/commit/3321c2d72ab7757dbdd38bdd99a76d89293dac8a.diff LOG: [clang] Add test for CWG794 "Base-derived conversion in member type of pointer-to-member conversion" (#121660) 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.
