Fair enough - all seems a bit unfortunate to be pushing these attributes through to places they don't technically apply to (both complicates the implementation, and might be confusing to users).

Thanks for trying the prototype - not clear what the right design is, so let's go with what you've got here.



================
Comment at: clang/lib/CodeGen/CGDebugInfo.cpp:1249
+  llvm::DIType *WrappedDI = getOrCreateType(WrappedTy, Unit);
+  if (Annotations.size() == 0)
+    return WrappedDI;
----------------
use `empty()` rather than `size() == 0`


================
Comment at: clang/lib/CodeGen/CGDebugInfo.cpp:1252
+
+  if (WrappedDI == nullptr)
+    WrappedDI = DBuilder.createUnspecifiedType("void");
----------------
probably write this as `if (!WrappedDI)`
