This is llvm.org/pr10367, right?

[LLVMdev] [RFC] Alias should not point to declarations
A long time ago (before r97733) we used to model the weakref attribute
by outputting a new declaration and a weak alias to it. This was
fairly buggy and we now implement weakref directly in clang, with the
same logic an assembler uses to implement .weakref (which is what gcc
prints).
One thing that was left from that old implementation is that we still
have alias to declarations and they are a
