[llvm-dev] cross-checking external declarations / debug info for declarations

[David Callahan via llvm-dev]

I was able to add a call to EmitFunctionDecl in
lib/CodeGen/CodeGenModule.cpp and then needed a corresponding LLVM change
to handle Subprogram¹s in the retained type vector.

The diff D18565 is marked Abandoned. What is the future plans for
supporting full-type consumers?
