| 42 | LuaJIT is a <b>Just-In-Time Compiler</b> for the Lua<sup>*</sup> | ||
| 43 | programming language. | ||
| 44 | </p> | ||
| 45 | <p> | ||
| 46 | LuaJIT is Copyright © 2005-2008 Mike Pall. | ||
| 47 | LuaJIT is open source software, released under the | ||

| 51 | * Lua is a powerful, dynamic and light-weight programming language | ||
| 52 | designed for extending applications. Lua is also frequently used as a | ||
| 53 | general-purpose, stand-alone language. More information about | ||
| 54 | Lua can be found at: <a href="http://www.lua.org/"><span class="ext">»</span> http://www.lua.org/</a> | ||
| 55 | </p> | ||
| 56 | <h2>Compatibility</h2> | ||
| 57 | <p> | ||
| 58 | LuaJIT implements the full set of language features defined by Lua 5.1. | ||
| 59 | The virtual machine (VM) is <b>API- and ABI-compatible</b> to the | ||
| 60 | standard Lua interpreter and can be deployed as a drop-in replacement. | ||
| 61 | </p> | ||
| 62 | <p> | ||
| 63 | LuaJIT offers more performance, at the expense of portability. It | ||
| 64 | currently runs on all popular operating systems based on <b>x86 CPUs</b> | ||
| 65 | (Linux, Windows, OSX etc.). It will be ported to x64 CPUs and other | ||
| 66 | platforms in the future, based on user demand and sponsoring. | ||
| 67 | </p> | ||
| 68 | |||
| 69 | <h2>Overview</h2> | ||
| 70 | <p> | ||
| 71 | LuaJIT has been successfully used as a <b>scripting middleware</b> in | ||
| 72 | games, 3D modellers, numerical simulations, trading platforms and many | ||
| 73 | other specialty applications. It combines high flexibility with high | ||
| 74 | performance and an unmatched <b>low memory footprint</b>: less than | ||
| 75 | <b>120K</b> for the VM plus less than <b>80K</b> for the JIT compiler. | ||
| 76 | </p> | ||
| 77 | <p> | ||
| 78 | LuaJIT has been in continuous development since 2005. It's widely | ||
| 79 | considered to be <b>one of the fastest dynamic language | ||
| 80 | implementations</b>. It has outperfomed other dynamic languages on many | ||
| 81 | cross-language benchmarks since its first release — often by a | ||
| 82 | substantial margin. Only now, in 2009, other dynamic language VMs are | ||
| 83 | starting to catch up with the performance of LuaJIT 1.x … | ||
| 84 | </p> | ||
| 85 | <p> | ||
| 86 | 2009 also marks the first release of the long-awaited <b>LuaJIT 2.0</b>. | ||
| 87 | The whole VM has been rewritten from the ground up and relentlessly | ||
| 88 | optimized for performance. It combines a high-speed interpreter, | ||
| 89 | written in assembler, with a state-of-the-art JIT compiler. | ||
| 90 | </p> | ||
| 91 | <p> | ||
| 92 | An innovative <b>trace compiler</b> is integrated with advanced, | ||
| 93 | SSA-based optimizations and a highly tuned code generation backend. This | ||
| 94 | allows a substantial reduction of the overhead associated with dynamic | ||
| 95 | language features. It's destined to break into the performance range | ||
| 96 | traditionally reserved for offline, static language compilers. | ||
