* Makefile.in (SIM_OBJS): Add sim-load.o.
* interp.c (target_byte_order): Delete. (sim_kind, myname, little_endian_p): New static locals. (init_pointers): Use little_endian_p instead of target_byte_order. (sim_resume): Likewise. (sim_open): Set sim_kind, myname. Set little_endian_p from -E arg. (sim_load): Return SIM_RC. New arg abfd. Call sim_load_file to load file into simulator. Set start address from bfd. (sim_create_inferior): Return SIM_RC. Delete arg start_address.
