[PATCH] D142162: [Dominators] Use GraphTraits::getEntryNode instead of front(). (NFC)

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Implement and use DomTreeNodeTraits for customization. Clients can implement DomTreeNodeTraitsCustom to provide custom ParentPtr, getEntryNode and getParent. There's also a default specialization if DomTreeNodeTraitsCustom is not implemented, that assume a Function-like NodeT. This is what is used for the existing DominatorTree and MachineDominatorTree.
