Full Changelog: 0.1.0...0.1.1

0.1.0

Significant performance improvement

We have re-designed the VM architecture and it resulted in significant performance improvement. See the design note for more details

Engine API (a.k.a multi Store support)

In this release, we deprecate Runtime-based APIs and introduced Engine API. The new API matches Wasm C API terminology, and allows per-instantiation imports configuration.

let engine = Engine()
let store = Store(engine: engine)

let instance = try module.instantiate(
    store: store,
    imports: [
        "printer": [
            "print_i32": Function(store: store, parameters: [.i32]) { _, args in
                print(args[0])
                return []
            }
        ]
    ]
)
let printAdd = instance.exports[function: "print_add"]!
try printAdd([.i32(42), .i32(3)])

Fuzz-tested code base

We setup fuzz testing infrastructure by LLVM libFuzzer and differential testing technique, and revealed several mis-compilation issues.
