[Xiang Zhang via Phabricator via llvm-commits]

================
Comment at: llvm/lib/Target/X86/X86PreTileConfig.cpp:328
+      if (I < BBVisitedInfo[I.MBB].LastShape)
+        I = BBVisitedInfo[I.MBB].LastShape;
+      // There're chances the MBB is sunk more than once. Record it to avoid
----------------
I am a little puzzle here, The I.MBB is all shape def reachable, but how can we make sure the BBVisitedInfo[I.MBB].LastShape is shape def reachable ? They may be not same BB.
