Thanks for this!

I might actually differ a bit in a preference of how we go about doing this. I would advocate for a dedicated Config method being added for this which is then called explicitly when fuzzing. That way fuzzing is self-documented in the Config creation of the fuzzer and then this is also available to all other users too.

Actually, shouldn't it belong to the fuzzing crate? It already creates config with some additional options by default:

https://github.com/bytecodealliance/wasmtime/blob/c202a8eeaf8f72a5e87d50ac2f0d58c9170b3488/crates/fuzzing/src/oracles.rs#L19-L29

I think it would be best to make it pub or pub(crate), use it as base for custom configurations in entire fuzzing create and enable NaN canonicalization flag here.

Yeah that's my thinking, we'd have a method on Config which is called by the fuzzing crate.

No, I meant to have a function that creates appropriate Config in the fuzzing crate. fuzz_default_config is already in the fuzzing crate.

@teapotd yes but the fuzzing crate depends on the wasmtime crate, and needs to call a public method on Config to enable nan canonicalization. The method needs to be defined in the wasmtime crate and then the fuzzing crate would call that.

@alexcrichton Ah, that's what you meant. Thanks!
