Trace-based compilation

Trace-based compilation is a method used by some programming language tools to improve performance. Instead of analyzing and optimizing the entire program all at once, it focuses on the most frequently executed sequences of instructions, called "traces." These traces are identified dynamically as the program runs. The system then compiles these hot paths into faster, optimized machine code, allowing the program to run more efficiently along its common routes. This approach adapts to actual usage patterns, enhancing speed for the parts of the program most often used, while maintaining flexibility for less common code paths.
