You are missing a crucial point. The compiler may emit the same exact loads and stores when it inlines memcpy() if it "knows" the objects are aligned properly. And it very much will do this. If the compiler is calling memcpy() in your build, it's only because gcc believes the the object is too big to optimally memcpy() inline. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html -------- Завершение пересылаемого сообщения -------- -- "Краски осени": Новый конкурс на Яндекс.Фотках http://fotki.yandex.ru/contest.xml?id=10 - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
