Re: is sim/common documented anywhere?

weird ... it does for me.  i don't think the rules added by the common make 
fragments swallow any errors ...

yes & no.  i think the core of the sim_engine_run loop is best left simple:

sim_engine_run (SIM_DESC sd,
                int next_cpu_nr, /* ignore  */
                int nr_cpus, /* ignore  */  
                int siggnal) /* ignore  */
  SIM_CPU *cpu;


  cpu = STATE_CPU (sd, 0);

  while (1)
      step_once (cpu);
      if (sim_events_tick (sd))
        sim_events_process (sd);

feel free to call "step_once" whatever you want -- there doesn't appear to be 
consistency atm.  but that func is where you'd put all the decode+execute
