[PATCH] D158776: [ConstraintElim] Handle trivial (ICMP_ULE, 0, B) in doesHold.

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/ConstraintElimination.cpp:741
+  if (Pred == CmpInst::ICMP_ULE && A == Constant::getNullValue(A->getType()))
+    return true;
   auto R = getConstraintForSolving(Pred, A, B);
----------------
Is it guaranteed that zero will be on the left?
