I've got most of gdb stub implemented to use hard break- and
watchpoints. There is one place where gdb wants to know whether a
breakpoint, access watch or read watch was hit, and also the data
address in case of a watchpoint.

I can't really figure that out with the registers of the current debug
unit. I would need a set of bits that indicate which checkpoint matched
the processor state when the trap was generated. Is that possible, Damjan?
