================
Comment at: lib/Target/AMDGPU/AMDGPUISelLowering.cpp:3170
+            DAG.getNode(ISD::SRL, SL, VT, LHS.getOperand(1), N->getOperand(1)));
+      }

----------------
@nhaehnle @arsenm I think this handles the BFE issue - I investigated putting this in DAGCombine but it caused a lot of noise on other targets - some improvements, some regressions.
