Abstract
A method and apparatus for coloring an interference graph eliminates register copy instructions in an instruction stream by taking into consideration the colors of a node's direct or transitive partners when choosing a color for a node. By assigning a color to a node that is also the color of a direct or transitive partner, register copy instructions between the two partners may be eliminated. If more than one of the partners at any given level are colored, one of the colors may be selected over the others using an appropriate heuristic, such as a scheme that weights the colors appropriately.
