Persistent annotation of syntax graphs for code optimization

This invention describes a system that helps compilers make computer programs run faster. It works by looking at the program's structure, like a map of its components, and identifying specific patterns or sections of code. Once a pattern is found, the system adds notes to it, detailing how that piece of code behaves, such as whether it changes external data or uses specific types of variables. This detailed information then guides the compiler to apply more effective optimizations, making the program more efficient.
