Lecture
This lecture discusses the inefficiencies in translation, such as always creating closures and performing indirect calls. It explores an improved translation method that splits the target function into a wrapper and a worker, enhancing efficiency. The lecture also covers hoisting functions, closure conversion, and the handling of closures in Scala. Additionally, it delves into dataflow analysis concepts like available expressions, live variables, reaching definitions, and very busy expressions, showcasing their importance in program optimization.
