GDB enables implementers to link gdb to a built-in simulator, so that a simulated target may be executed through use of the target sim command.
The simulator should be built as a library,
libsim.a, implementing the standard GDB
simulator interface. The location of the library is specified by
setting the gdb_sim parameter in
configure.tgt.
The interface consists of a set of functions which should be
implemented. The detailed specification is found in the header
remote-sim.h in the include directory.
sim_open. Initialize the simulator.
sim_close. Destroy the simulator instance,
including freeing any memory.
sim_load. Load a program into the simulator's
memory.
sim_create_inferior. Prepare to run the
simulated program. Don't actually run it until
sim_resume (see below) is called.
sim_read and
sim_write. Read and write bytes from and to
the simulator's memory.
sim_fetch_register and
sim_store_register. Read and write the
simulator's registers.
sim_info. Print information for the
info sim command.
sim_resume. Resume (or start) execution of
the simulated program.
sim_stop. Stop execution of the simulated
program.
sim_stop_reason. Return the reason why the
program stopped.
sim_do_command. Execute some arbitrary
command that the simulator supports.
