================
Comment at: lib/Transforms/Scalar/DeadStoreElimination.cpp:1210-1211
+  DenseMap<const Value *, unsigned> InstNums;
+  // ^ Post-order numbering of MemoryPhis and instructions, a) that throw, or b)
+  // are DSE candidates. Used to detect intervening MayThrows or loop latches
+  SmallVector<unsigned, 32> MayThrows;
