GDB drives the simulator through the sim_resume function, of which
there are a couple depending on what type of simulator is
implemented.

The sim_resume method takes a flag to indicate if the simulator should
single step or not, and this flag is used to set state within the
simulator object.

I would suggest figuring out which sim_resume method your simulator
uses, see how the single step flag is used, and then make use of this
same state within your sim_engine_run.

Hope that helps,
