Abstract
We discuss the problems involved in building a retargetable register
allocator for use in an optimizing compiler. While the popular "register
coloring" method is machine-independent, the allocator as a whole must
implement numerous machine-dependent decisions. We present the kinds
of information that must be parameterized in order to include register
allocation in an retargetable compiler back-end, and discuss a sample
solution.
