[PATCH] D23580: [GraphWriter] Change GraphWriter to use NodeRef in GraphTraits

[David Blaikie via llvm-commits]

dblaikie added a comment.

what's the printer used for? Would it be best to generalize it (perhaps adding another extension point to the graph traits, so NodeRefs can be printed out - with a default implementation for pointers)?
