Using Constraint Logic Programming to Formally Optimize 6502/6510 Assembly Code
Introduction This post is an experiment . A first step, a proof of concept, and also a personal exploration. The idea is to start talking not only about SQL Server and Database , but also about Artificial Intelligence , constraint solving , and data-driven reasoning applied to real, concrete technical problems. In this case, the problem comes from an old but fascinating domain: the MOS 6502 / 6510 CPU . Project Overview and Motivation This code represents the first concrete step of a broader project whose goal is to build a code optimizer for the MOS 6502 / 6510 CPU using Constraint Logic Programming , specifically ECLiPSe CLP(FD) . The long-term vision of the project is to explore whether formal constraint-based reasoning can be used to automatically discover provably optimal instruction sequences for real hardware, instead of relying on hand-written heuristics, pattern matching, or empirical benchmarks. Rather than simulating execution or enumerating progra...
