Hi guys,

I have a question:
Our processor (or1k) has a lot of HW debugging capabilities and I was
wondering what would be the best solution to include them into
user interface.

e.g.: We can create HW watchpoint as

"watchpoint_event" = $1234 == 506 && ( $50 > 70 && $50 <= 120 ||
!write_to_address_occured (4567))

(Sorry about this freaky pseudo code, but I hope you get my point)
We could surely add special command which would support such
functionality, but
I would like to have this functionality detected automaticaly using
break or hbreak.
Is this possible and how to do it. I read in documentation that
expessions are
translated to byte code. Where is that code and how should I intercept
that data?

The same point goes to catchpoints and trace.

thanks,
	Marko
