A minor update of a few other crates drops `semver` and `rustc_version`
from `Cargo.lock`. I've audited the deltas in versions for the other
crates here as well and they all look good.
* Update wasm-tools dependencies
This update brings in a number of features such as:
* The component model binary format and AST has been slightly adjusted
in a few locations. Names are dropped from parameters/results now in
the internal representation since they were not used anyway. At this
time the ability to bind a multi-return function has not been exposed.
* The `wasmparser` validator pass will now share allocations with prior
functions, providing what's probably a very minor speedup for Wasmtime
itself.
* The text format for many component-related tests now requires named
parameters.
* Some new relaxed-simd instructions are updated to be ignored.
I hope to have a follow-up to expose the multi-return ability to the
embedding API of components.
* Update audit information for new crates
* Upgrade to regalloc2 0.4.1.
Incorporates bytecodealliance/regalloc2#85, which fixes a fuzzbug
related to constraints and liverange splits.
* Add audit of regalloc2 upgrade.
* Update to cap-std 0.26.
This is primarily to pull in bytecodealliance/cap-std#271, the fix for #4936,
compilation on Rust nightly on Windows.
It also updates to rustix 0.35.10, to pull in bytecodealliance/rustix#403,
the fix for bytecodealliance/rustix#402, compilation on newer versions of
the libc crate, which changed a public function from `unsafe` to safe.
Fixes#4936.
* Update the system-interface audit for 0.23.
* Update the libc supply-chain config version.
* Cranelift: use regalloc2 constraints on caller side of ABI code.
This PR updates the shared ABI code and backends to use register-operand
constraints rather than explicit pinned-vreg moves for register
arguments and return values.
The s390x backend was not updated, because it has its own implementation
of ABI code. Ideally we could converge back to the code shared by x64
and aarch64 (which didn't exist when s390x ported calls to ISLE, so the
current situation is underestandable, to be clear!). I'll leave this for
future work.
This PR exposed several places where regalloc2 needed to be a bit more
flexible with constraints; it requires regalloc2#74 to be merged and
pulled in.
* Update to regalloc2 0.3.3.
In addition to version bump, this required removing two asserts as
`SpillSlot`s no longer carry their class (so we can't assert that they
have the correct class).
* Review comments.
* Filetest updates.
* Add cargo-vet audit for regalloc2 0.3.2 -> 0.3.3 upgrade.
* Update to regalloc2 0.4.0.
* Optimize the WASI `random_get` implementation.
Use `StdRng` instead of the `OsRng` in the default implementation of
`random_get`. This uses a userspace CSPRNG, making `random_get` 3x faster
in simple benchmarks.
* Update cargo-vet audits for cap-std 0.25.3.
* Update all cap-std packages to 0.25.3.
I looked through some of our smaller dependencies to vet them and add an
audit for them. These were the ones that were all "obviously correct" to
me before I ran out of steam reviewing other crates.
* Implement the remaining socket-related WASI functions.
The original WASI specification included `sock_read`, `sock_write`, and
`shutdown`. Now that we have some sockets support, implement these
additional functions, to make it easier for people porting existing code
to WASI.
It's expected that this will all be subsumed by the wasi-sockets
proposal, but for now, this is a relatively small change which should
hopefully unblock people trying to use the current `accept` support.
* Update to system-interface 0.22, which has fixes for Windows.
* Upgrade wasm-tools crates, namely the component model
This commit pulls in the latest versions of all of the `wasm-tools`
family of crates. There were two major changes that happened in
`wasm-tools` in the meantime:
* bytecodealliance/wasm-tools#697 - this commit introduced a new API for
more efficiently reading binary operators from a wasm binary. The old
`Operator`-based reading was left in place, however, and continues to
be what Wasmtime uses. I hope to update Wasmtime in a future PR to use
this new API, but for now the biggest change is...
* bytecodealliance/wasm-tools#703 - this commit was a major update to
the component model AST. This commit almost entirely deals with the
fallout of this change.
The changes made to the component model were:
1. The `unit` type no longer exists. This was generally a simple change
where the `Unit` case in a few different locations were all removed.
2. The `expected` type was renamed to `result`. This similarly was
relatively lightweight and mostly just a renaming on the surface. I
took this opportunity to rename `val::Result` to `val::ResultVal` and
`types::Result` to `types::ResultType` to avoid clashing with the
standard library types. The `Option`-based types were handled with
this as well.
3. The payload type of `variant` and `result` types are now optional.
This affected many locations that calculate flat type
representations, ABI information, etc. The `#[derive(ComponentType)]`
macro now specifically handles Rust-defined `enum` types which have
no payload to the equivalent in the component model.
4. Functions can now return multiple parameters. This changed the
signature of invoking component functions because the return value is
now bound by `ComponentNamedList` (renamed from `ComponentParams`).
This had a large effect in the tests, fuzz test case generation, etc.
5. Function types with 2-or-more parameters/results must uniquely name
all parameters/results. This mostly affected the text format used
throughout the tests.
I haven't added specifically new tests for multi-return but I changed a
number of tests to use it. Additionally I've updated the fuzzers to all
exercise multi-return as well so I think we should get some good
coverage with that.
* Update version numbers
* Use crates.io
* Cranelift: Use bump allocation in `remove_constant_phis` pass
This makes compilation 2-6% faster for Sightglass's bz2 benchmark:
```

bump.so is 1.02x to 1.06x faster than main.so!

```
* Add audit for `bumpalo`
* Add an audit of `arrayvec` version 0.7.2
* Remove unnecessary `collect` into `Vec`
I wasn't able to measure any perf difference here, but its nice to do anyways.
* Use a `SecondaryMap` for keeping track of summaries
* cranelift: Upgrade libm to 0.2.4
This resolves an issue with incorrect fmaf on the x86_64-pc-windows-gnu target under some inputs.
See: #4517
* supply-chain: Vet `libm` 0.2.4
This commit builds on bytecodealliance/wasm-tools#690 to add support to
testing of the component model to execute functions when running
`*.wast` files. This support is all built on #4442 as functions are
invoked through a "dynamic" API. Right now the testing and integration
is fairly crude but I'm hoping that we can try to improve it over time
as necessary. For now this should provide a hopefully more convenient
syntax for unit tests and the like.
