Re: Иное использование стека сопроцессора

витя ерыгин
Я по колдовал с hex-обознчениями.
В mmx регистры можно складировать значения
Дольше всего мучился с двойным складированием (  a b c d - a b m0: c m1: d   )
Всё из-за [ebp] . Не нашёл методом науч.тыка среди movd, нашёл среди movq , но это блин учетверённое слово!
