This revision is now accepted and ready to land.

I'd prefer we remove the redundant comments in TTIImpl.h (see below), but otherwise, LGTM.



================
Comment at: llvm/include/llvm/Analysis/TargetTransformInfoImpl.h:390
 
-  unsigned getMinPrefetchStride() { return 1; }
+  /// \return The minimum stride in bytes where it makes sense to
+  /// start adding SW prefetches.  Some HW prefetchers can handle
----------------
I don't see any value in repeating these interface comments here. They're already present on the declarations in TargetTransformInfo.h, and they'll get out of sync here.
