gdb breakpoint

[Vineet Sharma, Noida]

Hi,
     My simulator is synchronus and it does not have and harward
register(for breakpoint). So how can we implement the software
breakpoint/watc/step etc. .


Q2) Does the gdb runs simulator as a thread?
	If yes is it always the case or there are exception?

Q3)  When is sim_resume() is supposed to return after the return of the
simulator  or what?
	In other word what is the functinality of sim_resume?

Regards
Vineet
