Link to "A Generalized Algorithm for Graph-Coloring Register Allocation"

[Bruce]

This paper is being used as part of the register allocation algorithm
for the compiler. It shows how to generalize a graph coloring
algorithm for register allocation to be able to handle allocation
requests for different overlapping classes of registers.
