 734
 735         * mn10300-tdep.c: made a lot more generic, ripping out code
 736         from copied target (no more mn10300_scan_prologue,

 820         * mn10300-tdep.c (mn10300_push_arguments): rewrote,
 821         also removed code elsewhere that made use of RP_REGNUM.

 823         ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
 824         arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
 825         EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
