[PATCH] D68232: [DAGCombine] Match a greater range of rotate when not all bits are demanded.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: lib/CodeGen/SelectionDAG/DAGCombiner.cpp:548
+    SDValue MatchRotate(SDValue LHS, SDValue RHS, const SDLoc &DL);
+    SDValue MatchRotate(SDValue LHS, SDValue RHS, const SDLoc &DL,
+                        const APInt &DemandedBits);
----------------
The change to returning SDValue looks like an NFC that you can do right away?
