Detailed Description

A #Procedure optimization pass takes an existing procedure and changes it in a way that improves its performance when executed.

Oftentimes it would also be possible to implement a specific optimization directly during construction of the initial #Procedure. There is a trade-off between doing that or just building a "simple" procedure and then optimizing it uses separate optimization passes.

• Doing optimizations directly during construction is typically faster than doing it as a separate pass. However, it would be much harder to turn the optimization off when it is not necessary, making the construction potentially slower in those cases.
• Doing optimizations directly would also make code more complex, because it mixes the logic that generates the procedure from some other data with optimization decisions.
• Having a separate pass allows us to use it in different places when necessary.
• Having a separate pass allows us to enable and disable it easily to better understand its impact on performance.
