(sim_set_pc): Update prototype. (sim_read, sim_write): Ditto, and use unsigned char *buf. (sim_fetch_register, sim_store_register): Use unsigned char *buf. (sim_info): Pass printf function as argument, add verbose argument. (sim_stop_reason): Renamed from sim_stop_signal, fix prototype. * remote-sim.c (gdbsim_wait): Update call to sim_stop_reason. (gdbsim_files_info): Update call to sim_info.
