rampitec added inline comments.


================
Comment at: lib/Target/AMDGPU/AMDGPURewriteOutArguments.cpp:386
+            DL->getTypeSizeInBits(Val->getType())) {
+          assert(isVec3ToVec4Shuffle(EffectiveEltTy, Val->getType()));
+          Val = B.CreateShuffleVector(Val, UndefValue::get(Val->getType()),
----------------
That is probably legal for a source to cast pointer argument to anything. Looks like you need to check if that is a special case you are looking for rather than asserting.
