* Ensure GlobalSet on vectors are cast to Cranelift's I8X16 type
This is a fix related to the decision to use Cranelift's I8X16 type to represent Wasm's V128--it requires casting to maintain type correctness. See https://github.com/bytecodealliance/wasmtime/issues/1147.
* Enable SIMD spec test: simd_lane.wast
* Add documentation for building programs using AssemblyScript.
* Add the assemblyscript hello world as an example and display it inline.
* Move the AssemblyScript hello world into the docs directory.
That way Cargo doesn't try to run it like a Rust example.
* Minor code tidying.
* Document that `Linker::iter`'s iteration order is arbitrary.
* Add a few more tests for `wasmtime::Linker`.
* Refactor `Linker::compute_imports`.
- Extract the error message generation into a separate function.
- In the error message, sort the candidates.
* Fix a typo in a comment.
* Add `__rtti_base` to the list of allowed but deprecated exports.
* Don't print an Error message when a program exits normally.
* Update comments to reflect the current code.
* Also allow "table" as an exported table, which is used by AssemblyScript.
I'm not actually sure that it's possible to write `#[test]` in a
`proc-macro` crate. Regardless I don't think it's too too conventional,
so let's disable this for now.
Closes#1775
* Reactor support.
This implements the new WASI ABI described here:
https://github.com/WebAssembly/WASI/blob/master/design/application-abi.md
It adds APIs to `Instance` and `Linker` with support for running
WASI programs, and also simplifies the process of instantiating
WASI API modules.
This currently only includes Rust API support.
* Add comments and fix a typo in a comment.
* Fix a rustdoc warning.
* Tidy an unneeded `mut`.
* Factor out instance initialization with `NewInstance`.
This also separates instantiation from initialization in a manner
similar to https://github.com/bytecodealliance/lucet/pull/506.
* Update fuzzing oracles for the API changes.
* Remove `wasi_linker` and clarify that Commands/Reactors aren't connected to WASI.
* Move Command/Reactor semantics into the Linker.
* C API support.
* Fix fuzzer build.
* Update usage syntax from "::" to "=".
* Remove `NewInstance` and `start()`.
* Elaborate on Commands and Reactors and add a spec link.
* Add more comments.
* Fix wat syntax.
* Fix wat.
* Use the `Debug` formatter to format an anyhow::Error.
* Fix wat.
A full Eq implementation is no needed for ReservedValue, as we only need
to check whether a value is the reserved one. For entities (defined with
`entity_impl!`) this doesn't make much difference, but for more
complicated types this avoids generating redundant `Eq`s.
I hadn't realized before that the filetest backend for `test vcode` is
doing essentially what `compile` is doing, but for new (`MachInst`)
backends: it is just getting a disassembly and running it through
filecheck. There's no reason not to reuse `test compile` for the AArch64
tests as well.
This was motivated by the desire to have "this IR compiles successfully"
tests work on both x86 and AArch64. It seems this should work fine by
adding multiple `target` directives when a test case should be
compile-tested on multiple architectures.
This commit prevents updating the XMM save unwind operation offsets when a
frame pointer is not used, even though currently Cranelift always uses a
frame pointer.
This will prevent incorrect unwind information in the future when we start
omitting frame pointers.
