Lua trace JIT compiler using LLVM-C
FastLua is an trace JIT compiler that works as an Lua (5.3) extension.
There are only some minor modifications in the original interpreter.
Currently, FastLua uses the LLVM toolchain to generate native code (there are plans to change the backend).
For further information about Lua, see https://www.lua.org.
ATENTION: This is still on development state.
LLVM (only tested with version 3.9)
Run make <plataform (eg. linux)> in project root folder.
The build infrastructure is the same that Lua uses.
The usage should be equal to the standard Lua interpreter.
The compilation is done automatically when a hotspot is detected.
Since this is still a prototype, only few instructions will be compiled.
If the compilation fails, FastLua will fallback to the original interpreter and everything should work just fine.
FastLua use Lua tests and a custom test suite. Use runtests.sh to run the tests.
There is also a benchmark suite. Type runbenchmarks.sh to run it.
