  29 /* This is an implementation of sim_engine_abort that does not use
  30    longjmp, instead it just calls sim_io_error.  sim_io_error will
  31    jump right out of the simulator.

  33    It is intended as a holder for simulators that have started to use
  34    sim-core et al. but are not yet in a position to use sim-engine
  35    (the setjmp/longjmp code). */
