================
Comment at: llvm/lib/Target/AMDGPU/GCNHazardRecognizer.cpp:1173
            (MI.getOpcode() == AMDGPU::S_WAITCNT_DEPCTR &&
-            MI.getOperand(0).getImm() == 0xffe3);
+            AMDGPU::DepCtr::decodeFieldVmVsrc(MI.getOperand(0).getImm()) == 0);
   };
----------------
Strictly speaking changes like this one are not NFC, since the new code ignores the non-VmVsrc bits of the immediate value, but that seems like an obvious improvement.
