This commit adds a `compile` command to the Wasmtime CLI. The command can be used to Ahead-Of-Time (AOT) compile WebAssembly modules. With the `all-arch` feature enabled, AOT compilation can be performed for non-native architectures (i.e. cross-compilation). The `Module::compile` method has been added to perform AOT compilation. A few of the CLI flags relating to "on by default" Wasm features have been changed to be "--disable-XYZ" flags. A simple example of using the `wasmtime compile` command: ```text $ wasmtime compile input.wasm $ wasmtime input.cwasm ```
This is the wasmtime-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
