================
Comment at: llvm/lib/Transforms/Scalar/LoopLoadElimination.cpp:92
   /// Return true if the dependence from the store to the load has a
-  /// distance of one.  E.g. A[i+1] = A[i]
+  /// distance of one.
+  /// E.g. A[i+1] = A[i] (or A[i-1] = A[i] for descending loop)
----------------
nit:  maybe `absolute distance of one`?
