This commit updates all the wasm-tools crates that we use and enables
fuzzing of the module linking proposal in our various fuzz targets. This
also refactors some of the dummy value generation logic to not be
fallible and to always succeed, the thinking being that we don't want to
accidentally hide errors while fuzzing. Additionally instantiation is
only allowed to fail with a `Trap`, other failure reasons are unwrapped.
* Implement imported/exported modules/instances
This commit implements the final piece of the module linking proposal
which is to flesh out the support for importing/exporting instances and
modules. This ended up having a few changes:
* Two more `PrimaryMap` instances are now stored in an `Instance`. The value
for instances is `InstanceHandle` (pretty easy) and for modules it's
`Box<dyn Any>` (less easy).
* The custom host state for `InstanceHandle` for `wasmtime` is now
`Arc<TypeTables` to be able to fully reconstruct an instance's types
just from its instance.
* Type matching for imports now has been updated to take
instances/modules into account.
One of the main downsides of this implementation is that type matching
of imports is duplicated between wasmparser and wasmtime, leading to
posssible bugs especially in the subtelties of module linking. I'm not
sure how best to unify these two pieces of validation, however, and it
may be more trouble than it's worth.

* Update wat/wast/wasmparser
* Review comments
* Fix a bug in publish script to vendor the right witx
Currently there's two witx binaries in our repository given the two wasi
spec submodules, so this updates the publication script to vendor the
right one.
This patch implements, for aarch64, the following wasm SIMD extensions
i32x4.dot_i16x8_s instruction
https://github.com/WebAssembly/simd/pull/127
It also updates dependencies as follows, in order that the new instruction can
be parsed, decoded, etc:
wat to 1.0.27
wast to 26.0.1
wasmparser to 0.65.0
wasmprinter to 0.2.12
The changes are straightforward:
* new CLIF instruction `widening_pairwise_dot_product_s`
* translation from wasm into `widening_pairwise_dot_product_s`
* new AArch64 instructions `smull`, `smull2` (part of the `VecRRR` group)
* translation from `widening_pairwise_dot_product_s` to `smull ; smull2 ; addv`
There is no testcase in this commit, because that is a separate repo. The
implementation has been tested, nevertheless.
This commit extracts the two implementations of `Compiler` into two
separate crates, `wasmtime-cranelfit` and `wasmtime-lightbeam`. The
`wasmtime-jit` crate then depends on these two and instantiates them
appropriately. The goal here is to start reducing the weight of the
`wasmtime-environ` crate, which currently serves as a common set of
types between all `wasmtime-*` crates. Long-term I'd like to remove the
dependency on Cranelift from `wasmtime-environ`, but that's going to
take a lot more work.
In the meantime I figure it's a good way to get started by separating
out the lightbeam/cranelift function compilers from the
`wasmtime-environ` crate. We can continue to iterate on moving things
out in the future, too.
This commit is intended to update wasmparser to 0.59.0. This primarily
includes bytecodealliance/wasm-tools#40 which is a large update to how
parsing and validation works. The impact on Wasmtime is pretty small at
this time, but over time I'd like to refactor the internals here to lean
more heavily on that upstream wasmparser refactoring.
For now, though, the intention is to get on the train of wasmparser's
latest `main` branch to ensure we get bug fixes and such.
As part of this update a few other crates and such were updated. This is
primarily to handle the new encoding of `ref.is_null` where the type is
not part of the instruction encoding any more.
This somewhat cuts down on duplicate dependencies. `wast` is used in a much older version (`11.0.0`) by `witx`, and can be updated without issues there as well, but this at least gets us from 3 copies to 2.
The `wasmtime` crate currently lives in `crates/api` for historical
reasons, because we once called it `wasmtime-api` crate. This creates a
stumbling block for new contributors.
As discussed on Zulip, rename the directory to `crates/wasmtime`.
* Wasmtime 0.15.0 and Cranelift 0.62.0. (#1398)
* Bump more ad-hoc versions.
* Add build.rs to wasi-common's Cargo.toml.
* Update the env var name in more places.
* Remove a redundant echo.
* Bump Wasmtime to 0.14.0.
* Update the publish script for the wiggle crate wiggle.
* More fixes.
* Fix lightbeam depenency version.
* cargo update
* Cargo update wasi-tests too.
And add cargo update to the version-bump scripts.
* Enable jitdump profiling support by default
This the result of some of the investigation I was doing for #1017. I've
done a number of refactorings here which culminated in a number of
changes that all amount to what I think should result in jitdump support being
enabled by default:
* Pass in a list of finished functions instead of just a range to
ensure that we're emitting jit dump data for a specific module rather
than a whole `CodeMemory` which may have other modules.
* Define `ProfilingStrategy` in the `wasmtime` crate to have everything
locally-defined
* Add support to the C API to enable profiling
* Documentation added for profiling with jitdump to the book
* Split out supported/unsupported files in `jitdump.rs` to avoid having
lots of `#[cfg]`.
* Make dependencies optional that are only used for `jitdump`.
* Move initialization up-front to `JitDumpAgent::new()` instead of
deferring it to the first module.
* Pass around `Arc<dyn ProfilingAgent>` instead of
`Option<Arc<Mutex<Box<dyn ProfilingAgent>>>>`
The `jitdump` Cargo feature is now enabled by default which means that
our published binaries, C API artifacts, and crates will support
profiling at runtime by default. The support I don't think is fully
fleshed out and working but I think it's probably in a good enough spot
we can get users playing around with it!
* Cargo.lock: Update, to no longer use multiple versions of autocfg
* Update wasmtime-debug and wasmtime-profiling to current gimli 0.20.0
This also eliminates duplicate versions of gimli and arrayvec, and
eliminates the nodrop dependency entirely.
* Update wasmtime-profiling to goblin 0.1.3 and object 0.17.0
This also eliminates two duplicate versions of goblin, and duplicate
versions of proc-macro2, quote, syn, scroll_derive, and unicode-xid.
* Update wasmtime-profiling to current scroll 0.10.1
This eliminates duplicate versions of scroll.
* Update wasmtime-profiling to current target-lexicon 0.10.0
This eliminates duplicate versions of target-lexicon.
* Update wasmtime-interface-types to current walrus and wasm-webidl-bindings
This also eliminates the oldest of the three duplicate versions of
wasmparser.
* Update wasmtime-wast to current wast 8.0.0
This eliminates one of the duplicate versions of wast.
* Update to the latest spec_testsuite and dependencies.
Update to target-lexicon 0.10, cranelift 0.54, wast 0.6, faerie 0.14,
and the latest spec_testsuite.
For wast and cranelift-wasm, update the code for API changes.
* Factor out the code for matching f32, f64, and v128.
This takes the idea from #802 to split out `f32_matches`, `f64_matches`,
and `v128_matches` functions, which better factor out the matching
functionality between scalar and vector.
* Ensure `Trap` is returned for start function traps
Handle another case of errors coming out of instantiation, resolve a
FIXME, and remove an unneeded dependency from the wast testsuite crate.
* Run rustfmt
* Update the `*.wast` runner to use the `wasmtime` API
This commit migrates the `wasmtime-wast` crate, which executes `*.wast`
test suites, to use the `wasmtime` crate exclusively instead of the raw
support provided by the `wasmtime-*` family of crates.
The primary motivation for this change is to use `*.wast` test to test
the support for interface types, but interface types is only being added
in the `wasmtime` crate for now rather than all throughout the core
crates. This means that without this transition it's much more difficult
to write tests for wasm interface types!
A secondary motivation for this is that it's testing the support we
provide to users through the `wasmtime` crate, since that's the
expectation of what most users would use rather than the raw
`wasmtime-*` crates.
* Run rustfmt
* Fix the multi example
* Handle v128 values in the `wasmtime` crate
Ensure that we allocate 128-bit stack slots instead of 64-bit stack
slots.
* Update to master
* Add comment
* 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.
