Let's do the following in addition to the lsb_bitfield_op_p thing: 1. Replace the LO_SUM test in set_address_base by a call to must_be_base_p, 2. Replace the MULT || ASHIFT test in set_address_index by a call to must_be_index_p, 3. Add the new cases to must_be_index_p directly, with a comment saying that there are e.g. for the ARM. -- Eric Botcazou
