The x86 instruction set has been extended several times, introducing wider registers and datatypes and/or new functionality.
Famous quotes containing the word instructions:
“Realizing that his time was nearly spent, he gave full oral instructions about his burial and the manner in which he wished to be remembered.... A few minutes later, feeling very tired, he left the room, remarking, I have no disposition to leave this precious circle. I love to be here surrounded by my family and friends. Then he gave them his blessing and said, I am ready to go and I wish you goodnight.”
—For the State of New Hampshire, U.S. public relief program (1935-1943)
