Yes but the issue is one optimization inside GCC does not take into account the probability in one case. And really there is a bug in the linux kernel for not implementing the long long divide function (or really using libgcc) but that is a different story and is part of the issue there anyways. -- Pinski -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
