* Update wasm-tools crates
This brings in recent updates, notably including more improvements to
wasm-smith which will hopefully help exercise non-trapping wasm more.
* Fix some wat
* Update wasm-tools crates
* Update Wasm SIMD spec tests
* Invert 'experimental_x64_should_panic' logic
By doing this, it is easier to see which spec tests currently panic. The new tests correspond to recently-added instructions.
* Fix: ignore new spec tests for all backends
This commit goes through the dependencies that wasmtime has and updates
versions where possible. This notably brings in a wasmparser/wast update
which has some simd spec changes with new instructions. Otherwise most
of these are just routine updates.
This commit updates the various tooling used by wasmtime which has new
updates to the module linking proposal. This is done primarily to sync
with WebAssembly/module-linking#26. The main change implemented here is
that wasmtime now supports creating instances from a set of values, nott
just from instantiating a module. Additionally subtyping handling of
modules with respect to imports is now properly handled by desugaring
two-level imports to imports of instances.
A number of small refactorings are included here as well, but most of
them are in accordance with the changes to `wasmparser` and the updated
binary format for module linking.
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.
cc #2094
* 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 requires upgrading to wasmparser 0.67.0.
* There are no CLIF side changes because the CLIF `select` instruction is
polymorphic enough.
* on aarch64, there is unfortunately no conditional-move (csel) instruction on
vectors. This patch adds a synthetic instruction `VecCSel` which *does*
behave like that. At emit time, this is emitted as an if-then-else diamond
(4 insns).
* aarch64 implementation is otherwise straightforwards.
This will hopefully remove a small thorn in our side with periodic
nightly breakage due to nightly features changing. This commit moves
lightbeam to stable Rust, swapping out `staticvec` for `arrayvec` and
otherwise updating some dependencies (namely `dynasm`) to compile with
stable.
This then also updates CI appropriately to not use a pinned nightly and
instead us a floating `nightly` channel so we can head off any breakage
coming up ASAP.
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.
* Implement trap info in Lightbeam
* Start using wasm-reader instead of wasmparser for parsing operators
* Update to use wasm-reader, some reductions in allocation, support source location tracking for traps, start to support multi-value
The only thing that still needs to be supported for multi-value is stack returns, but we need to make it compatible with Cranelift.
* Error when running out of registers (although we'd hope it should be impossible) instead of panicking
