@weliveindetail I'm trying to add visibility attributes to all used functions and classes in libLLVM.so.  So far I've been been adding annotations to headers only, so I need to have the declarations visible when the implementation is complied so that the visibility attribute is applied.

If we don't want to expose these functions to the API, then I think I can special case them and just add the visibility attributes on the implementation.
