According to Willy Tarreau: > likely => __builtin_expect(!(x), 0) > unlikely => __builtin_expect((x), 0)
Well, I'm not sure about the polarity, but that unlikely() macro isn't good -- it the same old problem that first prompted my message, namely that it's nonportable when (x) has a pointer type. -- Chip Salzenberg - a.k.a. - <chip@pobox.com> "I wanted to play hopscotch with the impenetrable mystery of existence, but he stepped in a wormhole and had to go in early." // MST3K - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
