Superoptimizer: Exploring the Fascinating World of the Smallest Possible Program
Superoptimizer – A Look at the Smallest Program
I dive into the concept of the superoptimizer, a tool that searches for the absolute smallest and fastest version of a program. This exploration reveals how finding the minimal code can lead to surprising discoveries about compiler efficiency and the fundamental limits of computation. The journey highlights the intricate dance between human intuition and automated search in crafting perfect software.
The smallest program is not just a curiosity; it is the ultimate test of our understanding of computation and the hidden potential within every line of code.

Same author did the synthesis kernel with Carl Pu, I think? The Synthesis kernel was genius, but relied on self modifying code, so can't work with modern chips well.

A (relatively) new way to create a super optimizer is to use an egraph: https://egraphs-good.github.io/
These are nifty data structures that can quickly search the space of equivalent programs.

This has long been one of my favorite papers, if only for the opening example. When I walked through it, it was an eye opener to a different level of thinking about code, one that assembly and democoders are probably working in every day.
