+def WWM_COPY : AMDGPUGenericInstruction {
+  let OutOperandList = (outs unknown:$dst);
----------------
This should not be AMDGPUGenericInstruction, it's not a generic instruction. Should subclass from AMDGPUInst, and move to the other non-generic pseudos. AMDGPUGenericInstruction is for the G_AMDGPU_ globalisel pre-isel pseudos
