* Update wasmtime to 0.27 A couple of notes: - Now we are fair about unsafeness of runtime creation via an compiled artifact. This change was prompted by the change in wasmtime which made `deserialize` rightfully unsafe. Now `CodeSupplyMode` was hidden and the `create_runtime` now takes the blob again and there is now a new fn for creating a runtime with a compiled artifact. - This is a big change for wasmtime. They switched to the modern backend for code generation. While this can bring performance improvements, it can also introduce some problems. In fact, 0.27 fixed a serious issue that could lead to sandbox escape. Hence we need a proper burn in. This would require a change to PVF validation host as well. * Filter regalloc logging
A crate that provides means of executing/dispatching calls into the runtime.
There are a few responsibilities of this crate at the moment:
- It provides an implementation of a common entrypoint for calling into the runtime, both wasm and compiled.
- It defines the environment for the wasm execution, namely the host functions that are to be provided into the wasm runtime module.
- It also provides the required infrastructure for executing the current wasm runtime (specified
by the current value of
:codein the provided externalities), i.e. interfacing with wasm engine used, instance cache.
