================
Comment at: llvm/lib/Target/AMDGPU/AMDGPU.td:471
+  "true",
+  "Encoding format GFX10_A"
+>;
----------------
I realise you're just following the precedent set by GFX10_B, but is this terminology actually used in any documentation anywhere? And if not could we describe it a little better here?


================
Comment at: llvm/lib/Target/AMDGPU/SIISelLowering.cpp:7341
+    if (!Subtarget->hasGFX10_AEncoding())
+      emitRemovedIntrinsicError(DAG, DL, Op.getValueType());
+

> I've changed this to return. Thanks for catching that. But, it returns a UNDEF value instead of SDValue() so that it doesn't crash. I can change the behavior if that's preferred. 
Personally I would follow all the existing precedents and "return emitRemovedIntrinsicError(...)". I don't see any value in deliberately trying to make the compiler crash harder.
