This PR updates `wasmtime_wasi` crate by adjusting `poll_oneoff`'s
signature to that introduced in `wasi_common` in
CraneStation/wasi-common#137. This change is required in order to
fix#440.
* deps: bump wasmparser to 0.39.2
This has a bug fix for multi-value Wasm validation that is required for getting
the spec tests passing.
https://github.com/yurydelendik/wasmparser.rs/pull/135
* Update cranelift to 0.46.1 to get multi-value Wasm support
The `cranelift_wasm` APIs had to change a little bit to maintain state necessary
when translating multi-value Wasm blocks. The `translate_module` function now
returns a `ModuleTranslationState` that is borrowed during each function's
translation.
* Enable multi-value proposal's spec tests
This enables all the Wasm multi-value proposal's spec tests other than the ones
that rely on functions having more return values than registers available on the
target. That is not supported by cranelift yet.
* wasmtime-interface-types: always use multi-value Wasm
And remove the return pointer hacks that work around the lack of multi-value.
Changes:
* uses Rust edition 2018
* returns wasm32 errno directly rather than relying on
wasi_common::{host, memory} modules
* wraps extraction of memory and WASI context in a macro
* Simple module compilation cache
* Fix base64 encoding bug
* Use warn! everywhere in cache system
* Remove unused import
* Temporary workaround for long path on Windows
* Remove unused import for non-windows builds
* Add command line argument to enable cache system + apply minor review feedback
