gofuzz-shim is heavily inspired by go-118-fuzz-build,
but is rewritten from scratch. It does not have the same algorithm for conversion of
fuzzing-input to test-inputs, hence corpus is not reusable across these engines.
The data-conversion algorithm in gofuzz-shim if focused on allowing libfuzzer to have as much control as possible over the input, and making full use of the libfuzzer instrumentation data.
Very much work in progress.
