================
Comment at: lib/Transforms/Vectorize/SLPVectorizer.cpp:4334
     // If a store has multiple consecutive store candidates, search Stores
-    // array according to the sequence: from i+1 to e, then from i-1 to 0.
+    // array according to the sequence: Idx-1, Idx+1, Idx-2, Idx+2, ...
     // This is because usually pairing with immediate succeeding or preceding
