 741
 742         * mn10300-tdep.c: made a lot more generic, ripping out code
 743         from copied target (no more mn10300_scan_prologue,

 830         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
 831         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
 832         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
