If your lab keeps all the orignal 51 opcodes, you don't have to do anything. If your lab adds opcodes, sdcc just won't use the new instructions. But if your labs makes changes to hardware registers (sfr), those changes can be accounted for by creating your own special header file which you will include in any firmware you write for your private 51 device.
