[PATCH] D78861: [Attributor] [WIP] Track AA dependency using dependency graph

[Kuter Dinel via Phabricator via llvm-commits]

kuter added a comment.

This does not compile for me. The compiler error that I get is about creating a `GraphTraits` specialization outside of the `llvm` namespace.
When i put the `GraphTraits` in llvm namespace it does compile.

But when I run it I get a sefault.
