* x64: Remove incorrect `amode_add` lowering rules
This commit removes two incorrect rules as part of the x64 backend's
computation of addressing modes. These two rules folded a zero-extended
32-bit computation into the address mode operand, but this isn't correct
as the 32-bit computation should be truncated to 32-bits but when folded
into the address mode computation it happens with 64-bit operands,
meaning truncation doesn't happen.
* Add release notes
* Add release notes for 3.0.1
* Update some version directives for crates in Wasmtime
* Mark anything with `publish = false` as version 0.0.0
* Mark the icache coherence crate with the same version as Wasmtime
* Fix manifest directives
* Update 0.40.0 release notes
Not a ton happened in terms of user-facing improvements here so I
outlined some internal changes as well. The cumulative effect of
improving compile times is Sightglass showing 30-40% improvements for
major benchmarks. Additionally I wrote down a note indicating that this
is likely the last `0.*` release and the next release of Wasmtime on
September 20 is planned to be 1.0.
* Remove perf-related relnotes
* Call out s390x simd at the top-level
* Upgrade to regalloc2 v0.2.3 to get bugfix from bytecodealliance/regalloc2#60.
* Update RELEASES.md.
* Update two compile tests based on slightly shifting regalloc output.
* Decouple some more `Config` methods from each other
This commit decouples validation of stack sizes and guard sizes until
`Engine::new` to avoid odd interactions between the order of invocation
of `Config` methods.
* Fix C API
* Typos
This commit refactored `Config` to use a seperate `CompilerConfig` field instead
of operating on `CompilerBuilder` directly to make all its methods idempotent.
Fixes#4189
* Refactor away the `Instantiator` type in Wasmtime
This internal type in Wasmtime was primarily used for the module linking
proposal to handle instantiation of many instances and refactor out the
sync and async parts to minimize duplication. With the removal of the
module linking proposal, however, this type isn't really necessary any
longer. In working to implement the component model proposal I was
looking already to refactor this and I figured it'd be good to land that
ahead of time on `main` separate of other refactorings.
This commit removes the `Instantiator` type in the `instance` module.
The type was already private to Wasmtime so this shouldn't have any
impact on consumers. This allows simplifying various code paths to avoid
another abstraction. The meat of instantiation is moved to
`Instance::new_raw` which should be reusable for the component model as
well.
One bug is actually fixed in this commit as well where
`Linker::instantiate` and `InstancePre::instantiate` failed to check
that async support was disabled on a store. This means that they could
have led to a panic if used with an async store and a start function
called an async import (or an async resource limiter yielded). A few
tests were updated with this.
