where should not. Currently we are using QTy->isIncompleteType(&ND) to check incomplete type. But before doing that, need to instantiate for a class template specialization or a class member of a class template specialization, or an array with known size of such..., so that we know it is really incomplete type. To fix this using RequireCompleteType instead. The new test is added into "test/OpenMP/target_update_messages.cpp" The different of using RequireCompleteType is when emit incomplete type, an additional note is also emitted to point to where incomplete type is declared. Because this change, many tests are needed to be fixed by adding additional note. This is to fix https://bugs.llvm.org/show_bug.cgi?id=50508 Differential Revision: https://reviews.llvm.org/D107200
