Clang-CFG: A tool based on Clang LibTooling

Introduction

The tool is based on clang libtooling technology, used to generate control-flow-graph for C/C++ code.

The tool is a static python library, which could be invoke directly in python.

Usage

• Firstly, download the repository
• use cd clang-cfg change into the directory
• use mkdir build create a directory for binary files
• use cd build change into the binary directory
• use cmake .. to create MakeFiles
• use make to build the project

For an alpha version, I haven't provide python wrapper for the project and shoud be import directly

• run cd build/clang-cfg/pybind change into the directory of static library
• run `python -c "import clang_cfg" to test

Tips

• This project based on llvm, it will take long time to download and build llvm as a third party project
• This project based on pybind11, which needs to open -frtti option of compiler. The default compile option of llvm doesn't open it.
