[PATCH] D26633: AMDGPU/GCN: Exit early in hazard recognizer if there is no vreg argument

[Matt Arsenault via llvm-commits]

arsenm added inline comments.


================
Comment at: lib/Target/AMDGPU/GCNHazardRecognizer.cpp:399-403
   if (VDataIdx != -1)
     VDataRCID = Desc.OpInfo[VDataIdx].RegClass;
+  else
+    return -1;
 
----------------
Could you invert this so it's an if (== -1) return -1
