While bringing in no major updates for Wasmtime I've taken this
opportunity to list myself for `cargo vet` with wildcard audits of this
family of crates. That means I shouldn't need to further add any more
entries in the future for updating these crates and additionally any
other organizations using these audits will automatically be able to
have audits for version that I publish.
While here I also ran `cargo vet prune` which was able to remove a
number of our exemptions.
* ci: unpin the wasi-nn tasks from an older Ubuntu
Previously, OpenVINO's lack of APT packages for Ubuntu 22.04 (`jammy`)
prevented us from upgrading the GitHub runner to use `ubuntu-latest`. I
updated the `install-openvino-action` to substitute in the `focal`
packages in this case (this is what the OpenVINO team considers the fix)
so this pin should no longer be necessary. Fixes#5408.

* Adding in trampoline compiling method for ISA
* Adding support for indirect call to memory address
* Refactoring frame to externalize defined locals, so it removes WASM depedencies in trampoline case
* Adding initial version of trampoline for testing
* Refactoring trampoline to be re-used by other architectures
* Initial wiring for winch with wasmtime
* Add a Wasmtime CLI option to select `winch`
This is effectively an option to select the `Strategy` enumeration.
* Implement `Compiler::compile_function` for Winch
Hook this into the `TargetIsa::compile_function` hook as well. Currently
this doesn't take into account `Tunables`, but that's left as a TODO for
later.
* Filling out Winch append_code method
* Adding back in changes from previous branch
Most of these are a WIP. It's missing trampolines for x64, but a basic
one exists for aarch64. It's missing the handling of arguments that
exist on the stack.
It currently imports `cranelift_wasm::WasmFuncType` since it's what's
passed to the `Compiler` trait. It's a bit awkward to use in the
`winch_codegen` crate since it mostly operates on `wasmparser` types.
I've had to hack in a conversion to get things working. Long term, I'm
not sure it's wise to rely on this type but it seems like it's easier on
the Cranelift side when creating the stub IR.
* Small API changes to make integration easier
* Adding in new FuncEnv, only a stub for now
* Removing unneeded parts of the old PoC, and refactoring trampoline code
* Moving FuncEnv into a separate file
* More comments for trampolines
* Adding in winch integration tests for first pass
* Using new addressing method to fix stack pointer error
* Adding test for stack arguments
* Only run tests on x86 for now, it's more complete for winch
* Add in missing documentation after rebase
* Updating based on feedback in draft PR
* Fixing formatting on doc comment for argv register
* Running formatting
* Lock updates, and turning on winch feature flags during tests
* Updating configuration with comments to no longer gate Strategy enum
* Using the winch-environ FuncEnv, but it required changing the sig
* Proper comment formatting
* Removing wasmtime-winch from dev-dependencies, adding the winch feature makes this not necessary
* Update doc attr to include winch check
* Adding winch feature to doc generation, which seems to fix the feature error in CI
* Add the `component-model` feature to the cargo doc invocation in CI
To match the metadata used by the docs.rs invocation when building docs.
* Add a comment clarifying the usage of `component-model` for docs.rs
* Correctly order wasmtime-winch and winch-environ in the publish script
* Ensure x86 test dependencies are included in cfg(target_arch)

This commit introduces the `winch-environ` crate. This crate's responsibility is
to provide a shared implementatation of the `winch_codegen::FuncEnv` trait,
which is Winch's function compilation environment, used to resolve module and
runtime specific information needed by the code generation, such as resolving
all the details about a callee in a WebAssembly module, or resolving specific
information from the `VMContext`.
As of this change, the implementation only includes the necessary pieces to
resolve a function callee in a WebAssembly module. The idea is to evolve the
`winch_codegen::FuncEnv` trait as we evolve Winch's code generation.
This implements Godbolt Compiler Explorer-like functionality for Wasmtime and
Cranelift. Given a Wasm module, it compiles the module to native code and then
writes a standalone HTML file that gives a split pane view between the WAT and
ASM disassemblies.
* Enable the native target by default in winch
Match cranelift-codegen's build script where if no architecture is
explicitly enabled then the host architecture is implicitly enabled.
* Refactor Cranelift's ISA builder to share more with Winch
This commit refactors the `Builder` type to have a type parameter
representing the finished ISA with Cranelift and Winch having their own
typedefs for `Builder` to represent their own builders. The intention is
to use this shared functionality to produce more shared code between the
two codegen backends.
* Moving compiler shared components to a separate crate
* Restore native flag inference in compiler building
This fixes an oversight from the previous commits to use
`cranelift-native` to infer flags for the native host when using default
settings with Wasmtime.
* Move `Compiler::page_size_align` into wasmtime-environ
The `cranelift-codegen` crate doesn't need this and winch wants the same
implementation, so shuffle it around so everyone has access to it.
* Fill out `Compiler::{flags, isa_flags}` for Winch
These are easy enough to plumb through with some shared code for
Wasmtime.
* Plumb the `is_branch_protection_enabled` flag for Winch
Just forwarding an isa-specific setting accessor.
* Moving executable creation to shared compiler crate
* Adding builder back in and removing from shared crate
* Refactoring the shared pieces for the `CompilerBuilder`
I decided to move a couple things around from Alex's initial changes.
Instead of having the shared builder do everything, I went back to
having each compiler have a distinct builder implementation. I
refactored most of the flag setting logic into a single shared location,
so we can still reduce the amount of code duplication.
With them being separate, we don't need to maintain things like
`LinkOpts` which Winch doesn't currently use. We also have an avenue to
error when certain flags are sent to Winch if we don't support them. I'm
hoping this will make things more maintainable as we build out Winch.
I'm still unsure about keeping everything shared in a single crate
(`cranelift_shared`). It's starting to feel like this crate is doing too
much, which makes it difficult to name. There does seem to be a need for
two distinct abstraction: creating the final executable and the handling
of shared/ISA flags when building the compiler. I could make them into
two separate crates, but there doesn't seem to be enough there yet to
justify it.

This notably updates `wasmparser` for updates to the relaxed-simd
proposal and an implementation of the function-references proposal.
Additionally there are some minor bug fixes being picked up for WIT and
the component model.
This change adds a basic coredump generation after a WebAssembly trap
was entered. The coredump includes rudimentary stack / process debugging
information.
A new CLI argument is added to enable coredump generation:
```
wasmtime --coredump-on-trap=/path/to/coredump/file module.wasm
```
See ./docs/examples-coredump.md for a working example.
Refs https://github.com/bytecodealliance/wasmtime/issues/5732
This audit is needed for #5619. I'm going ahead and updating Cargo.toml
and Cargo.lock at the same time because no source code changes are
required for this update.
Rework br_table to use BlockCall, allowing us to avoid adding new nodes during ssa construction to hold block arguments. Additionally, many places where we previously matched on InstructionData to extract branch destinations can be replaced with a use of branch_destination or branch_destination_mut.
* Update world-selection in `bindgen!` macro
Inspired by bytecodealliance/wit-bindgen#494 specifying a world or
document to bindgen is now optional as it's inferred if there's only one
`default world` in a package's documents.
* Add cargo-vet entry
* Update wasm-tools crates
Pulls in a new component binary format which should hopefully be the
last update for awhile.
* Update cargo vet configuration
This commit includes a set of changes that add initial support for `wasi-threads` to Wasmtime:
* feat: remove mutability from the WasiCtx Table
This patch adds interior mutability to the WasiCtx Table and the Table elements.
Major pain points:
* `File` only needs `RwLock<cap_std::fs::File>` to implement
`File::set_fdflags()` on Windows, because of [1]
* Because `File` needs a `RwLock` and `RwLock*Guard` cannot
be hold across an `.await`, The `async` from
`async fn num_ready_bytes(&self)` had to be removed
* Because `File` needs a `RwLock` and `RwLock*Guard` cannot
be dereferenced in `pollable`, the signature of
`fn pollable(&self) -> Option<rustix::fd::BorrowedFd>`
changed to `fn pollable(&self) -> Option<Arc<dyn AsFd + '_>>`
[1] da238e324e/src/fs/fd_flags.rs (L210-L217)
* wasi-threads: add an initial implementation
This change is a first step toward implementing `wasi-threads` in
Wasmtime. We may find that it has some missing pieces, but the core
functionality is there: when `wasi::thread_spawn` is called by a running
WebAssembly module, a function named `wasi_thread_start` is found in the
module's exports and called in a new instance. The shared memory of the
original instance is reused in the new instance.
This new WASI proposal is in its early stages and details are still
being hashed out in the [spec] and [wasi-libc] repositories. Due to its
experimental state, the `wasi-threads` functionality is hidden behind
both a compile-time and runtime flag: one must build with `--features
wasi-threads` but also run the Wasmtime CLI with `--wasm-features
threads` and `--wasi-modules experimental-wasi-threads`. One can
experiment with `wasi-threads` by running:
```console
$ cargo run --features wasi-threads -- \
--wasm-features threads --wasi-modules experimental-wasi-threads \
<a threads-enabled module>
```
Threads-enabled Wasm modules are not yet easy to build. Hopefully this
is resolved soon, but in the meantime see the use of
`THREAD_MODEL=posix` in the [wasi-libc] repository for some clues on
what is necessary. Wiggle complicates things by requiring the Wasm
memory to be exported with a certain name and `wasi-threads` also
expects that memory to be imported; this build-time obstacle can be
overcome with the `--import-memory --export-memory` flags only available
in the latest Clang tree. Due to all of this, the included tests are
written directly in WAT--run these with:
```console
$ cargo test --features wasi-threads -p wasmtime-cli -- cli_tests
```
[spec]: https://github.com/WebAssembly/wasi-threads
[wasi-libc]: https://github.com/WebAssembly/wasi-libc
This change does not protect the WASI implementations themselves from
concurrent access. This is already complete in previous commits or left
for future commits in certain cases (e.g., wasi-nn).
* wasi-threads: factor out process exit logic
As is being discussed [elsewhere], either calling `proc_exit` or
trapping in any thread should halt execution of all threads. The
Wasmtime CLI already has logic for adapting a WebAssembly error code to
a code expected in each OS. This change factors out this logic to a new
function, `maybe_exit_on_error`, for use within the `wasi-threads`
implementation.
This will work reasonably well for CLI users of Wasmtime +
`wasi-threads`, but embedders will want something better in the future:
when a `wasi-threads` threads fails, they may not want their application
to exit. Handling this is tricky, because it will require cancelling the
threads spawned by the `wasi-threads` implementation, something that is
not trivial to do in Rust. With this change, we defer that work until
later in order to provide a working implementation of `wasi-threads` for
experimentation.
[elsewhere]: https://github.com/WebAssembly/wasi-threads/pull/17
* review: work around `fd_fdstat_set_flags`
In order to make progress with wasi-threads, this change temporarily
works around limitations induced by `wasi-common`'s
`fd_fdstat_set_flags` to allow `&mut self` use in the implementation.
Eventual resolution is tracked in
https://github.com/bytecodealliance/wasmtime/issues/5643. This change
makes several related helper functions (e.g., `set_fdflags`) take `&mut
self` as well.
* test: use `wait`/`notify` to improve `threads.wat` test
Previously, the test simply executed in a loop for some hardcoded number
of iterations. This changes uses `wait` and `notify` and atomic
operations to keep track of when the spawned threads are done and join
on the main thread appropriately.
* various fixes and tweaks due to the PR review

* generate tables inline, rather than delyaing them to after the decision tree has been generated
* avoid allocating new vectors by using slices into the sorted contiguous ranges
* avoid generating some unconditional jumps
* output differences in test output using the similar crate for easier debugging
Most of these optimizations are in the egraph `cprop.isle` rules now,
making a separate crate unnecessary.
Also I think the `udiv` optimizations here are straight-up wrong (doing
signed instead of unsigned division, and panicking instead of preserving
traps on division by zero) so I'm guessing this crate isn't seriously
used anywhere.
At the least, bjorn3 confirms that cg_clif doesn't use this, and I've
verified that Wasmtime doesn't either.
Closes#1090.
Nothing major pulled in here, but wanted to update to the latest
versions which enable tail calls by default. When used in Wasmtime,
however, the feature is disabled without the possibility of being
enabled since it's not implemented.

* Adding in the foundations for Winch `filetests`
This commit adds two new crates into the Winch workspace:
`filetests` and `test-macros`. The intent is to mimic the
structure of Cranelift `filetests`, but in a simpler way.
* Updates to documentation
This commits adds a high level document to outline how to test Winch
through the `winch-tools` utility. It also updates some inline
documentation which gets propagated to the CLI.
* Updating test-macro to use a glob instead of only a flat directory
* Update WIT tooling used by Wasmtime
This commit updates the WIT tooling, namely the wasm-tools family of
crates, with recent updates. Notably:
* bytecodealliance/wasm-tools#867
* bytecodealliance/wasm-tools#871
This updates index spaces in components and additionally bumps the
minimum required version of the component binary format to be consumed
by Wasmtime (because of the index space changes). Additionally WIT
tooling now fully supports `use`.
Note that WIT tooling doesn't, at this time, fully support packages and
depending on remotely defined WIT packages. Currently WIT still needs to
be vendored in the project. It's hoped that future work with `cargo
component` and possible integration here could make the story about
depending on remotely-defined WIT more ergonomic and streamlined.
* Fix `bindgen!` codegen tests
* Add a test for `use` paths an implement support
* Update to crates.io versions of wasm-tools
* Uncomment codegen tests
* Wasmtime: Add `Config::disable_cache`
* bench-api: Always disable the cache
* bench-api: Always get a `Config` from CLI flags
This commit fixes an issue that I ran into just now where benchmarking
one `*.so` with `--engine-flags` was giving wildly unexpected results
comparing to something without `--engine-flags`. The root cause here
appears to that when specifying `--engine-flags` the CLI parsing code is
used to create a `Config` and when omitted a `Config::new` instance is
created. The main difference between these is that for the CLI caching
is enabled by default and for `Config::new` it is not. Coupled with the
fact that caching doesn't really work for the `main` branch this ended
up giving wild results.
The fix here is to first always use the CLI parsing code to create a
`Config` to ensure that a config is consistently created. Next the
`--disable-cache` flag is unconditionally passed to the CLI parsing to
ensure that compilation actually happens.
Once applied this enables comparing an engine without flags and an
engine with flags which provides consistent results.
* Fix compile error

Fuzz additional targets in the cranelift-icache target. The list of targets fuzzed is controlled by the targets enabled in fuzz/Cargo.toml.
This PR also reworks how instruction disabling is done in function generator, moving the deny-list to a function to make the decision at runtime instead of compile time.

This adds support for `.wat` tests in `cranelift-filetest`. The test runner
translates the WAT to Wasm and then uses `cranelift-wasm` to translate the Wasm
to CLIF.
These tests are always precise output tests. The test expectations can be
updated by running tests with the `CRANELIFT_TEST_BLESS=1` environment variable
set, similar to our compile precise output tests. The test's expected output is
contained in the last comment in the test file.
The tests allow for configuring the kinds of heaps used to implement Wasm linear
memory via TOML in a `;;!` comment at the start of the test.
To get ISA and Cranelift flags parsing available in the filetests crate, I had
to move the `parse_sets_and_triple` helper from the `cranelift-tools` binary
crate to the `cranelift-reader` crate, where I think it logically
fits.
Additionally, I had to make some more bits of `cranelift-wasm`'s dummy
environment `pub` so that I could properly wrap and compose it with the
environment used for the `.wat` tests. I don't think this is a big deal, but if
we eventually want to clean this stuff up, we can probably remove the dummy
environments completely, remove `translate_module`, and fold them into these new
test environments and test runner (since Wasmtime isn't using those things
anyways).
