================
Comment at: llvm/lib/Transforms/Scalar/SimpleLoopUnswitch.cpp:322
     // nodes for values used in the no-longer-nested loop.
-    formLCSSA(*OldContainingL, DT, &LI, nullptr);
+    formLCSSA(*OldContainingL, DT, &LI, SE);
 
----------------
This change is required to preserve current behavior in cases when it's valid: sometimes invalidation of SCEV through VH actually worked as intended.
