* Add unimplemented stubs for Cranelift interfaces
Cranelift changes to FuncEnvironment, TargetEnvironment, and GlobalInit (see https://github.com/bytecodealliance/cranelift/pull/1073) require these changes to compile wasmtime.
* Upgrade Cranelift to 0.52.0
This commit uses the `*.witx` files describing the current wasi API to
reduce the boilerplate used to define implementations in the
`wasmtime-wasi` crate. Eventually I'd like to remove lots of boilerplate
in the `wasi-common` crate too, but this should at least be a good start!
The boilerplate removed here is:
* No need to list each function to add it to the
`wasmtime_runtime::Module` being created
* No need to list the signature of the function in a separate
`syscalls.rs` file.
Instead the `*.witx` file is processed in a single-use macro inside the
`wasmtime-wasi` crate. This macro uses the signatures known from
`*.witx` to automatically register with the right type in the wasm
module as well as define a wrapper that the wasm module will call into.
Functionally this is all the same as before, it's just defined in a
different way now!
The shim generated by this macro which wasmtime calls into only uses
`i32`/`i64`/etc wasm types, and it internally uses `as` casts to convert
to the right wasi types when delegating into the `wasi-common` crate.
One change was necessary to get this implemented, however. The functions
in `wasi-common` sometimes took `WasiCtx` and sometimes took a slice of
memory. After this PR they uniformly all require both `WasiCtx` and
memory so the wrappers can be auto-generated. The arguments are ignored
if they weren't previously required.
* Fix fuzz target compilation.
* Bump version to 0.7.0
* Temporarily disable fuzz tests
Temporarily disable fuzz tests until https://github.com/bytecodealliance/cranelift/issues/1216 is resolved.
* Fix publish-all.sh to not modify the witx crate.
* Remove the "publish = false" attribute from Lightbeam.
* Add a README.md for wasmtime-interface-types.
* Remove the "rust" category.
This fixes the following warning:
warning: the following are not valid category slugs and were ignored: rust. Please see https://crates.io/category_slugs for the list of all category slugs.
* Mark wasmtime-cli as "publish = false".
* Sort the publishing rules in topological order.
Also, publish nightly-only crates with cargo +nightly.
* General Cargo.toml cleanup.
- Remove travis-ci attributes.
- Remove "experimental" badges from actively-developed crates.
- Reflow some long lines.
- Use dependency features consistently.
- Add readme attributes
* Update WASI to the latest trunk.
This notably adds a .gitignore file for the WASI directory.
