ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:8156
+  if (OrigLoop->getHeader() == BB)
+    return BlockMaskCache[BB];
+
----------------
It may create a new item in BlockMaskCache with nullptr value. Do you need to check that the user actually expects it?
