LuaJIT Architecture Overview
How LuaJIT's tracing JIT works vs the standard Lua VM interpreter.
What Is LuaJIT?
LuaJIT is a Just-In-Time compiler for Lua 5.1. It is significantly faster than the standard Lua VM for numeric and loop-heavy code, while remaining 100% compatible.
Two Execution Modes
LuaJIT has two modes: the interpreter (a fast bytecode interpreter, faster than PUC Lua's) and the JIT compiler (traces hot loops to native machine code).
