Comment at: ../../ver4/lib/Transforms/Vectorize/LoopVectorize.cpp:7047-7049
+      // I do not compare "gather" cost vs "interleave pattern", I just assume
+      // that each target provides reasonable MaxInterleaveFactor that
+      // makes the "interleave pattern" profitable. When InterleaveFactor
----------------
Why don't you just compare the costs? You wouldn't need to make this assumption anymore.
