================
Comment at: llvm/lib/Transforms/Scalar/IndVarSimplify.cpp:1409
+    // wrap". getLoopInvariantExitCondDuringFirstIterations knows how to deal
+    // with umin in a smart way, but umin(a, b) - 1 will likely won't simplify.
+    // So we manually construct umin(a - 1, b - 1).
----------------
will likely won't
