  25 /* This is an implementation of sim_engine_abort that does not use
  26    longjmp, instead it just calls sim_io_error.  sim_io_error will
  27    jump right out of the simulator.
  28
  29    It is intended as a holder for simulators that have started to use
  30    sim-core et al. but are not yet in a position to use sim-engine
  31    (the setjmp/longjmp code). */
