#+title: Llvm-normalizer #+subtitle: A LLVM bitcode normalizer to support the Discover analyzer

• Prerequisites: ** External libraries:

  • For backward-cpp:

    #+begin_src sh

    install LLVM and Clang 11 (or the suitable version)

    sudo apt-get install llvm-11-dev clang-11 libclang-11-dev

    install other libraries

    sudo apt-get install libedit-dev #+end_src

** This tool:

• LLVM framework

• Installation

  • Modify the file CMakeLists.txt to update LLVM_CMAKE_PATH_HINTS to the CMake folder corresponding the installed LLVM, (version 11.1 is preferred). For examples:

    #+begin_src cmake set(LLVM_CMAKE_PATH_HINTS "$HOME/llvm/llvm-11/lib/cmake/llvm" # manually installed "/usr/lib/llvm-11/lib/cmake/llvm/" # Ubuntu installed #+end_src

  • Add the llvm bin path to PATH

  • Eg: Add export PATH=/usr/local/opt/llvm/bin:$PATH in /.bash_profile

  • Build by CMake:

    #+begin_src sh mkdir build cd build cmake ../ make #+end_src
