| This patch diagnoses a missing ‘typename’ keyword on nested template types like A<T>::B<U>, to fix llvm.org/pr16909. In addition to fixing an accepts-invalid, in C++11 such types would cause assertion failures and/or invalid LLVM IR when used with ‘auto’. I’m not 100% sure if the changes to test/CXX/basic/basic.lookup/basic.lookup.qual/class.qual/p2.cpp are desirable, or if we should suppress the missing ‘typename’ diagnostic when we’re already recovering on X<T>::X<T>. I’m open to suggestions :-) Ben |
