[PATCH] D55768: [TargetLowering] Add DemandedElts mask to SimplifyDemandedBits (PR40000)

[JF Bastien via Phabricator via llvm-commits]

jfb added inline comments.


================
Comment at: llvm/trunk/lib/CodeGen/SelectionDAG/TargetLowering.cpp:1901
-                           ? APInt::getAllOnesValue(VT.getVectorNumElements())
-                           : APInt(1, 1);
   computeKnownBitsForTargetNode(Op, Known, DemandedElts, TLO.DAG, Depth);
----------------
This leaves `VT` unused. I've removed it in r349377.
