-LuaJIT is a Just-In-Time Compiler for the Lua* -programming language. -
--LuaJIT is Copyright © 2005-2011 Mike Pall. -LuaJIT is open source software, released under the -» MIT license. -
--* Lua is a powerful, dynamic and light-weight programming language -designed for extending applications. Lua is also frequently used as a -general-purpose, stand-alone language. More information about -Lua can be found at: » http://www.lua.org/ -
-Compatibility
--LuaJIT implements the full set of language features defined by Lua 5.1. -The virtual machine (VM) is API- and ABI-compatible to the -standard Lua interpreter and can be deployed as a drop-in replacement. -
--LuaJIT offers more performance, at the expense of portability. It -currently runs on all popular operating systems based on -x86 or x64 CPUs (Linux, Windows, OSX etc.) or embedded -systems based on ARM (Android, iOS) or PPC CPUs. -Other platforms will be supported in the future, based on user demand -and sponsoring. -
- -Overview
--LuaJIT has been successfully used as a scripting middleware in -games, 3D modellers, numerical simulations, trading platforms and many -other specialty applications. It combines high flexibility with high -performance and an unmatched low memory footprint: less than -125K for the VM plus less than 85K for the JIT compiler (on x86). -
--LuaJIT has been in continuous development since 2005. It's widely -considered to be one of the fastest dynamic language -implementations. It has outperformed other dynamic languages on many -cross-language benchmarks since its first release — often by a -substantial margin. In 2009 other dynamic language VMs started to catch up -with the performance of LuaJIT 1.x. Well, I couldn't let that slide. ;-) -
--2009 also marks the first release of the long-awaited LuaJIT 2.0. -The whole VM has been rewritten from the ground up and relentlessly -optimized for performance. It combines a high-speed interpreter, -written in assembler, with a state-of-the-art JIT compiler. -
--An innovative trace compiler is integrated with advanced, -SSA-based optimizations and a highly tuned code generation backend. This -allows a substantial reduction of the overhead associated with dynamic -language features. -
--It's destined to break into the » performance -range traditionally reserved for offline, static language compilers. -
