Special purpose instruction set processors (lSPS) challenge compilers because of instruction level par-allelism, small numbers of registers, and highly spe-cialized register capabilities. Many traditionally sepa-rate subproblems in code generation have been unified and jointly optimized within a single integer linear pro-gramming (ILP) model. ILP modeling provides a pow-erful methodology for for generating high-quality code for a variety of ISPS. 1
