Mike Pall Style Guide
Overview
Mike Pall created LuaJIT, widely considered one of the most impressive JIT compilers ever written. A single developer achieved performance competitive with production JVMs while maintaining a tiny codebase. His work demonstrates that deep understanding of hardware and algorithms beats large teams with brute force.
Core Philosophy
"Measure, don't guess."
"The fastest code is code that doesn't run."
"Understand your hardware or it will humble you."
Pall believes in ruthless optimization through deep understanding—knowing the CPU so well that you can predict cycle counts by reading assembly.
Design Principles
- Trace-Based Compilation: Optimize what actually runs, not what might run.
