In #3186, we found an issue that requires patching the spec interpreter for now. Our plan is to have a `fuzzing` branch in our spec-repo mirror that lets us make these fixes locally before they are upstreamed. This PR updates the build script for the spec-interpreter wrapper crate to clone this particular `fuzzing` branch instead of the main branch.
Fuzzing Infrastructure for Wasmtime
This crate provides test case generators and oracles for use with fuzzing.
These generators and oracles are generally independent of the fuzzing engine
that might be using them and driving the whole fuzzing process (e.g. libFuzzer
or AFL). As such, this crate does not contain any actual fuzz targets
itself. Those are generally just a couple lines of glue code that plug raw input
from (for example) libFuzzer into a generator, and then run one or more
oracles on the generated test case.
If you're looking for the actual fuzz target definitions we currently have, they
live in wasmtime/fuzz/fuzz_targets/* and are driven by cargo fuzz and
libFuzzer.
