================
Comment at: test/CodeGen/AMDGPU/wqm.ll:104
   %src1 = call float @llvm.amdgcn.buffer.load.f32(<4 x i32> undef, i32 %idx1, i32 0, i1 0, i1 0)
   %out = fadd float %src0, %src1
   %out.0 = bitcast float %out to i32

I tried adding that, but one of the pre-existing functions in the test assert-fails. Something about it wanting to use scratch with -O0, but it isn't set up correctly. I'd be inclined to punt on this, since it's not related to WWM.
