// To estimate the number of times the loop body was executed, we want to
// know the number of times the backedge was taken, vs. the number of times
// we exited the loop.
- // The branch weights give us almost what we want, since they were adjusted
- // from the raw counts to provide a better probability estimate. Remove
- // the adjustment by subtracting 1 from both weights.
