Breakpoints #43

Closed pineman closed 2 months ago

pineman commented 3 months ago

Try to break execution before the instruction is actually executed, somehow. Hard to do because pc is constant for at least 4 cycles, and obviously we don't want to pause execution 4 times in a row

@pineman ?

pineman commented 2 months ago

two things:

it used to be a problem that breakpoints matched on each t_cycle of the instruction
additionally it used to break after the instruction had ran (when the last t_cycle had already mutated the cpu's state, as we do) if those problems don't exist anymore we can close this

I believe these issues are no longer a problem
