[PATCH] D152730: [ConstraintElim] Add A < B if A is an increasing phi for A != B.

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/ConstraintElimination.cpp:1122
+  Info.addFactForInductionPhi(cast<CmpInst>(And->getOperand(0)), Pred, A, B,
+                              CB.NumIn, CB.NumOut, DFSInStack, DT, LI);
   // Optimistically add fact from first condition.
----------------
Why is this only done for the "and" case and not for normal dominating conditions?
