[PATCH] D35374: AMDGPU: Fix handling of div_scale with undef inputs

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added inline comments.


================
Comment at: lib/Target/AMDGPU/SIISelLowering.cpp:3625
     if (!Param)
-      return DAG.getUNDEF(VT);
+      return DAG.getMergeValues({ DAG.getUNDEF(VT), DAG.getUNDEF(MVT::i1) }, DL);
 
----------------
Is it really needed? If the parameter required to be a constant why not just error out?
