New Revision: 280845
URL: http://llvm.org/viewvc/llvm-project?rev=280845&view=rev
Log:
Add a few more test for []-style uuid attributes.
- Should diag on a function (clang-cl warns; it's an error in cl)
- Test the attribute on nested classes (clang-cl is more permissive and more
self-consistent than cl here)
