Abstract
A processor performs out-of-order execution of a first instruction and a second instruction after the first instruction in program order, the first instruction includes source and destination indicators, the source indicator specifies a source of data, the destination indicator specifies a destination of the data, the first instruction instructs the processor to move the data from the source to the destination, the second instruction specifies a source indicator that specifies a source of data. A rename unit updates the second instruction source indicator with the first instruction source indicator if there are no intervening instructions that write to the source or to the destination of the first instruction and the second instruction source indicator matches the first instruction destination indicator.
