URL: https://github.com/llvm/llvm-project/commit/ef2c8274dfa216078436c6acfe0274a43a737242 DIFF: https://github.com/llvm/llvm-project/commit/ef2c8274dfa216078436c6acfe0274a43a737242.diff LOG: [clang] Add test for C++ DR2390 DR2390 clarifies that the argument to __has_cpp_attribute() needs to be macro-expanded. Clang already supports this and tests it explicitly in clang/test/Preprocessor/has_attribute.cpp. Copy the test over to clang/test/CXX/drs/ so the make_cxx_drs script picks it up.
