* Make `FunctionInfo` public and `CompiledModule::func_info` return it. * Make the `StackMapLookup` trait unsafe. * Add comments for the purpose of `EngineHostFuncs`. * Rework ownership model of shared signatures: `SignatureCollection` in conjunction with `SignatureRegistry` is now used so that the `Engine`, `Store`, and `Module` don't need to worry about unregistering shared signatures. * Implement `Func::param_arity` and `Func::result_arity` in terms of `Func::ty`. * Make looking up a trampoline with the module registry more efficient by doing a binary search on the function's starting PC value for the owning module and then looking up the trampoline with only that module. * Remove reference to the shared signatures from `GlobalRegisteredModule`.
This is the wasmtime-jit crate, which contains JIT-based execution
for wasm, using the wasm ABI defined by wasmtime-environ and the
runtime support provided by wasmtime-runtime.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
