Lua is a powerful, dynamic and light-weight programming language. It may be embedded or used as a general-purpose, stand-alone language. LuaJIT is Copyright E<copy> 2005-2017 Mike Pall, released under the E<rchevron> MIT open source license. =head2 Compatibility Windows Linux BSD OSX POSIX Embedded Android iOS PS3 PS4 PS Vita Xbox 360 Xbox One GCC Clang LLVM MSVC x86 x64 ARM ARM64 PPC MIPS32 MIPS64 Lua 5.1 API+ABI + JIT + BitOp + FFI Drop-in DLL/.so =head2 Overview 3x - 100x 115 KB VM 90 KB JIT 63 KLOC C 24 KLOC ASM 11 KLOC Lua LuaJIT has been successfully used as a B<scripting middleware> in games, appliances, network and graphics apps, numerical simulations, trading platforms and many other specialty applications. It scales from embedded devices, smartphones, desktops up to server farms. It combines high flexibility with E<rchevron> high performance and an unmatched B<low memory footprint>. LuaJIT has been in continuous development since 2005. It's widely considered to be B<one of the fastest dynamic language implementations>. It has outperformed other dynamic languages on many cross-language benchmarks since its first release E<mdash> often by a substantial margin. For B<LuaJIT 2.0>, the whole VM has been rewritten from the ground up and relentlessly optimized for performance. It combines a B<high-speed interpreter>, written in assembler, with a B<state-of-the-art JIT compiler>. An innovative B<trace compiler> is integrated with advanced, SSA-based optimizations and highly tuned code generation backends. A substantial reduction of the overhead associated with dynamic languages allows it to break into the performance range traditionally reserved for offline, static language compilers. =head2 More ...
