So, rather than having to have a list of which targets provide
a monitor_defs[], I would suggest that we make the API implemented
by the target be a function, like:
const MonitorDef *target_monitor_defs(void);
(which just returns a pointer to a static const array in
the target-*/monitor.c file). Then you can add a file
stubs/target-monitor-defs.c which provides the "stub" version
of this function (just returns a pointer to the no-commands
array). The link process will arrange that the stub version
is pulled in for any target that doesn't provide its own
implementation of the function.
Other than that, I suspect we can improve the separation
out of target-specific things, but this is a good
improvement and it'll be easier to do the rest as
incremental fixes on top of this later.
thanks
