If you want to build interference graphs, or register allocators
in general, then you should be reading my thesis.


    author="Preston Briggs",
    title="Register Allocation via Graph Coloring",
    school="Rice University",
    year=1992,
    month=apr


especially the chapter on engineering. At the time, I thought I
pretty much beat the subject to death, though there have been a couple
of small improvements since, along with several "improvements" that
are best avoided.
