The Ethereum EVM JIT

EVM JIT is a library for just-in-time compilation of Ethereum EVM code. It can be used to substitute classic interpreter-like EVM Virtual Machine in Ethereum client.

Build

Linux / Ubuntu

  1. Install llvm-3.5-dev package
  2. For Ubuntu 14.04 using LLVM deb packages source: http://llvm.org/apt
  3. For Ubuntu 14.10 using Ubuntu packages
  4. Build library with cmake
  5. mkdir build && cd $_
  6. cmake .. && make
  7. Install library
  8. sudo make install
  9. sudo ldconfig

OSX

  1. Install llvm35
  2. brew install llvm35 --disable-shared --HEAD
  3. Build library with cmake
  4. mkdir build && cd $_
  5. cmake -DLLVM_DIR=/usr/local/lib/llvm-3.5/share/llvm/cmake .. && make
  6. Install library
