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:
```
compilation :: cycles :: benchmarks/bz2/benchmark.wasm

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.
