--- Comment #5 from David Edelsohn <dje at gcc dot gnu.org> ---
The issue is *why* the branch predictor is not predicting it correctly. It may
be that the details of the branch predictor are causing the prediction to
conflict with another branch, for example, nullifying the correct prediction.
One should not leap to the conclusion that the predictor is not initialized.
