* h8500-tdep.c (saved_pc_after_call): The size of the pc is memory model dependent. (segmented_command, unsegmented_command, _initialize_h8500_tdep): New commands to change memory model. * remote-7000.c (initialize_remote_e7000): Change name of snoop command. * remote-hms.c (hms_load): Remove breakpoints when loaded. (hms_wait): Use new status structure (hms_open): Push the target here. (hms_before_main_loop): Not here. (supply_val, hms_fetch_register, hms_store_register): Cope with H8/500 names too. * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print all registers in a compact way.
