"Memory-mapped data" was meant to imply the first of the two 
alternatives, so I think your expectations match mine.

I'm not sure what you mean by this.  You're not supposed to know what's 
inside it, but you are supposed to pass it back to lto_resolve_type_ref, 
when you encounter a reference to a type in the body of the function.
