LuaJIT is a B<Just-In-Time Compiler> (JIT) for the E<rchevron> Lua
|
|
programming language. Lua is a powerful, dynamic and light-weight
|
|
programming language. It may be embedded or used as a general-purpose,
|
|
stand-alone language.

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.
