[PATCH] D119654: [SDAG] enable binop identity constant folds for add/sub

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:3333
 
+  if (N0->getOpcode() == ISD::FREEZE && N0.hasOneUse())
+    N0 = N0->getOperand(0);
----------------
Some general solution? FREEZE should be dropped much sooner, no?
