[PATCH] D69915: [AMDGPU] Fix bug introduced in 47a5c36b37f0

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUTargetTransformInfo.cpp:741
     if (Shuffle->changesLength())
-      return -1;
+      BaseT::getUserCost(U, Operands);
 
----------------
I don't see how this works? Shouldn't this be returning instead of falling through?
