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

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