Interesting. I had a project that I wanted to use libFuzzer with custom instruction instrumentation. I never quite figured out how to pass back the custom instrumentation data back to libFuzzer.

This project seems to do just that by calling __sanitizer_cov_trace_cmp4. In retrospect, this seems like the obvious solution, and quite brilliant of this project to do that!
