Libraries

Help you implement JIT

• AsmJit - Complete x86/x64 JIT and Remote Assembler for C++
• DynASM
• LibJIT
• LLVM - MCJIT
• LLVM - ORC - Successor to MCJIT
• GCC - libgccjit
• GNU lightning - a library that generates assembly language code at run-time
• Xbyak - JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
• sljit - a stack-less platform independent JIT compiler
• MIR - a new JIT backend in C being developed by a Redhat GCC maintainer
• NanoJIT - a small JIT engine originally written by Adobe for Flash
• nj - a JIT engine written in C++ based on Eclipse OMR. Eclipse OMR is used in IBM's Java implementation, but the JIT engine is generic
• Cranelift - A Rust powered JIT compiler for x86-64, aarch64 and s390x created by the Wasmtime team for their WASI interpreter.

Comes with JIT support

• Python

  • Numba - NumPy aware dynamic Python compiler using LLVM

Programming Languages Implementation

• Julia

• Python

  • PyPy
  • Pyston - performance-oriented Python implementation built using LLVM and modern JIT techniques
  • Pyjion - JIT for Python based upon CoreCLR

• Lua

  • LuaJIT - An extremely fast Lua Just-in-Time compiler and interpreter.
  • MoonJIT - Just-In-Time Compiler for the Lua Programming language. Fork of LuaJIT to continue development
  • Ravi - a derivative/dialect of Lua 5.3 with limited optional static typing and an LLVM powered JIT compiler
  • RaptorJIT - a fork of LuaJIT focused on predictably high performance.
  • LuaJIT Remake - A LuaJIT Remake that leverages new techniques like "Copy & Patch" JIT and an interpreter generated by the semantical description of LuaJIT Bytecodes.

• JavaScript

  • V8 - High-performance Javascript and Webassembly engine developed by google around the "Sea of Nodes" concept
  • SpiderMonkey - Firefox's Javascript and Webassembly engine using the WarpMokey JIT engine
  • JavaScriptCore - High-performance Javascript and Webassembly engine developed by Apple for WebKit. Uses the B3 backend.
  • Chakra - Microsoft's JavaScript engine. Used to be the JS engine of Explorer and the early MSEdge.
  • IV - Javascript engine written in C++ that supports ECMAScript 262 5.1.
  • BESEN - Javascript engine written in object Pascal.
  • Higgs - Javascript engine written in D. Made by Maxime Chevalier-Boisvert, the same fella who participated in YJIT cited below.
