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

[Jakub Kuderski via Phabricator via llvm-commits]

kuhar added inline comments.


================
Comment at: llvm/include/llvm/Support/GenericDomTree.h:476
     if (!isPostDominator()) {
-      NodeT &Entry = A->getParent()->front();
+      NodeT &Entry = *GraphTraits<NodeT *>::getEntryNode(A);
       if (A == &Entry || B == &Entry)
----------------
Consider moving the graph traits type to the class definition (together with other typedefs) or to a new trait like in D141260.
