The definitions of `wasmtime::component::Val::Float{32,64}` mirrored
`wasmtime::Val::F{32,64}` by using integers as their wrapped types,
storing the bit representation of their floating point values.
This was necessary for the core Wasm `f32`/`f64` types because Rust
floats don't have guaranteed NaN bit representations.
The component model `float32`/`float64` types require NaN
canonicalization, so we can use normal Rust `f{32,64}` instead.
Closes #5480
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.
