Please add more AST tests. You seem to only have one, which is the static in a cbuffer.

I believe all of the AST work should be correct at this point. Can you test global scalars, global struct with member functions, etc.. Make the sure AST is correct in those cases.

Also, we could do some of the same tests to check the codegen when optmizations are disabled. Then we can add and test the fix up pass later.
