This, on the other hand, is concerning. It needs to reflect the debug_info section, otherwise we can't use debug_names to answer queries like "find A::B::C::D".
It would be better if the BOLT compiler produced either a "parent_not_indexed" entry, or  no parent at all, or implement the nameless parent. All of these allow LLDB to correctly answer the query above, but what BOLT is currently doing does not
