[PATCH] D60125: [ScheduleDAGRRList] Recompute topological ordering on demand.

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/ScheduleDAGRRList.cpp:1488
+  if (!Interferences.empty())
+    Topo.fixOrder();
   // All candidates are delayed due to live physical reg dependencies.
----------------
Where exactly do we query the topological order relative to this call to fixOrder()?  Do we need to fixOrder() inside the loop?
