AFL uses (ID of previous BB >> 1) XOR (ID of current BB) as the unique ID for basic block transitions.Why do we need to do the right shifting for the previous BB?
AFL uses (ID of previous BB >> 1) XOR (ID of current BB) as the unique ID for basic block transitions.
Why do we need to do the right shifting for the previous BB?
to handle cases where a branch connects multiple BBs
to handle cases where a BB loops back to itself
