Program fuzzer

Introduction

Very WIP/PoC code. Proceed with caution.

Many thanks to lcamtuf, the AFL people, John Regehr and the C-Reduce people, and the GCC people.

Usage

1. Download AFL to the current directory.
2. Build it.
3. Build your compiler using afl-gcc.
4. Change $AFL_PATH in make.sh if necessary.
5. Look for execlp in main.cc and point it to your instrumented compiler.
6. Run make.sh.
7. Run ./main.

License

The project includes snippets from AFL (Apache 2.0) and gcc (GPL 3), therefore this project is naturally GPL 3 as well.
