* Make-common.in (sim-options.o, sim-load.o): Add rules for.
(sim_main_headers): Add sim-trace.h. * run.c (exec_bfd, target_byte_order): Delete. (main): Pass -E <endian> to sim_open. Delete code to load sections, call sim_load instead. Check return code of sim_create_inferior. * sim-base.h (CURRENT_STATE): Define. (sim_state_base): Make typedef. New members options, prog_argv, prog_bfd, text_{section,start,end}, start_addr, simcache_size, mem_size, memory [+ corresponding access macros]. (sim_cpu_base): New typedef. * sim-trace.h: New file. * sim-basics.h: #include it. * sim-load.c: New file.
