Major API-incompatible changes include: - Introduce TrapCode::UnreachableCodeReached, used for unreachable in wasm. - cranelift-wasm's `declare_signature` now takes its signature by value - cranelift-wasm's `declare_table_elements` `elems` parameter now takes a boxed slice - Remove cranelift-wasm's `ModuleEnvironment`'s `get_signature`, `get_num_func_imports`, `get_func_type`, and `get_global`.
This crate provides module-level functionality, which allow multiple functions and data to be emitted with Cranelift and then linked together.
This crate is structured as an optional layer on top of cranelift-codegen. It provides additional functionality, such as linking, however users that require greater flexibility don't need to use it.
A Module is a collection of functions and data objects that are linked
together. Backend is a trait that defines an interface for backends
that compile modules into various forms. Most users will use one of the
following Backend implementations:
SimpleJITBackend, provided by cranelift-simplejit, which JITs code to memory for direct execution.FaerieBackend, provided by cranelift-faerie, which emits native object files.
