I don't think this has happened in awhile but I've run a `cargo update`
as well as trimming some of the duplicate/older dependencies in
`Cargo.lock` by updating some of our immediate dependencies as well.
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.
* Validate modules while translating
This commit is a change to cranelift-wasm to validate each function body
as it is translated. Additionally top-level module translation functions
will perform module validation. This commit builds on changes in
wasmparser to perform module validation interwtwined with parsing and
translation. This will be necessary for future wasm features such as
module linking where the type behind a function index, for example, can
be far away in another module. Additionally this also brings a nice
benefit where parsing the binary only happens once (instead of having an
up-front serial validation step) and validation can happen in parallel
for each function.
Most of the changes in this commit are plumbing to make sure everything
lines up right. The major functional change here is that module
compilation should be faster by validating in parallel (or skipping
function validation entirely in the case of a cache hit). Otherwise from
a user-facing perspective nothing should be that different.
This commit does mean that cranelift's translation now inherently
validates the input wasm module. This means that the Spidermonkey
integration of cranelift-wasm will also be validating the function as
it's being translated with cranelift. The associated PR for wasmparser
(bytecodealliance/wasmparser#62) provides the necessary tools to create
a `FuncValidator` for Gecko, but this is something I'll want careful
review for before landing!
* Read function operators until EOF
This way we can let the validator take care of any issues with
mismatched `end` instructions and/or trailing operators/bytes.
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.
- Create the ELF image from Compilation
- Create CodeMemory from the ELF image
- Link using ELF image
- Remove creation of GDB JIT images from crates/debug
- Move make_trampoline from compiler.rs
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.
* 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.
* 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.
* Migrate back to `std::` stylistically
This commit moves away from idioms such as `alloc::` and `core::` as
imports of standard data structures and types. Instead it migrates all
crates to uniformly use `std::` for importing standard data structures
and types. This also removes the `std` and `core` features from all
crates to and removes any conditional checking for `feature = "std"`
All of this support was previously added in #407 in an effort to make
wasmtime/cranelift "`no_std` compatible". Unfortunately though this
change comes at a cost:
* The usage of `alloc` and `core` isn't idiomatic. Especially trying to
dual between types like `HashMap` from `std` as well as from
`hashbrown` causes imports to be surprising in some cases.
* Unfortunately there was no CI check that crates were `no_std`, so none
of them actually were. Many crates still imported from `std` or
depended on crates that used `std`.
It's important to note, however, that **this does not mean that wasmtime
will not run in embedded environments**. The style of the code today and
idioms aren't ready in Rust to support this degree of multiplexing and
makes it somewhat difficult to keep up with the style of `wasmtime`.
Instead it's intended that embedded runtime support will be added as
necessary. Currently only `std` is necessary to build `wasmtime`, and
platforms that natively need to execute `wasmtime` will need to use a
Rust target that supports `std`. Note though that not all of `std` needs
to be supported, but instead much of it could be configured off to
return errors, and `wasmtime` would be configured to gracefully handle
errors.
The goal of this PR is to move `wasmtime` back to idiomatic usage of
features/`std`/imports/etc and help development in the short-term.
Long-term when platform concerns arise (if any) they can be addressed by
moving back to `no_std` crates (but fixing the issues mentioned above)
or ensuring that the target in Rust has `std` available.
* Start filling out platform support doc
This commit removes the usage of the `failure` crate and finishes up the
final pieces of the migration to `std::error::Error` and `anyhow`. The
`faerie` crate was updated to pull in its migration from `failure` to
`anyhow` as well.
* 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.
