[PATCH] D78291: [NFC][DAGCombine] Adding three helper functions and change the getNegatedExpression to negateExpression

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/TargetLowering.h:3547
+  virtual SDValue negateExpression(SDValue Op, SelectionDAG &DAG, bool LegalOps,
+                                   bool OptForSize, unsigned Depth = 0) const;
+
----------------
Its annoying that we're introducing negateExpression that will then go away again in D77319 - is there anyway to avoid creating negateExpression?
