instruction commits Rely on a hardware mechanism that operates like ROB Instructions are marked by the compiler as speculative and include an indicator of how many branches the instruction was speculatively moved across and what branch action (taken/not taken) the compiler assumed The original location of SI is marked by a sentinel, which tells HW that earlier SI is no longer speculative …
