llvm IR implementation of the F1 fuzzer (https://github.com/vrthra/F1)
To execute any of the handwritten IR files (basic_handwritten_gram.ll or slightly_complex_handwritten_gram.ll), just compile it with "clang " and then execute "./a.out".
These are the IR files corresponding to basic_gram.json and slightly_complex_gram.json.
To generate an IR file corresponding to any grammar, please run python3 main.py <grammarfile>.
The next steps are printed on the terminal.
