Interesting. I see you're doing this when expanding V_MOV_B64_PSEUDO, but I don't really understand when we use V_MOV_B64_PSEUDO in the first place. copyPhysReg() does not generate it, instead it copies the logic from here to emit V_PK_MOV_B32. So does that mean you need to add your V_LSHLREV_B64_e64 code to copyPhysReg too?
