| // - Since the 'ordinary' namespace includes functions, data, typedefs, |
| // ObjC interfaces, thecurrent algorithm is a bit naive (resulting in one |
| // entity for 2 different types). For example: |
| // |
| // module1.m: @interface Foo @end Foo *x; |
| // module2.m: void Foo(int); |
| // |
| // - Since the unique name spans translation units, static data/functions |
| // within a CXTranslationUnit are *not* currently represented by entities. |
| // As a result, there will be no entity for the following: |
| // |
| // module.m: static void Foo() { } |
| // |
