================
Comment at: lib/Analysis/LoopAccessAnalysis.cpp:1075
+    APInt Offset(PtrBitWidth, 0);
+    Ptr->stripAndAccumulateInBoundsConstantOffsets(DL, Offset);
+    OffValPair.push_back(std::make_pair(Offset.getSExtValue(), Val));
----------------
Thanks to @dberlin and @wmi - I now realize this is too simplistic.
It will handle cases where the offsets are constant, but not when all the offsets are variable, but the variables have constant differences from each other.

Anyway that can be handled separately. Could you add a FIXME here, please?
