- some tests don't pass because of bad interactions with the system's
libunwind; ignore them for now.
- the page size on mac aarch64 is 16K, not 4K; tweak some tests which
were expecting 4K or multiples of 4K pages to use a multiple of host page size
instead.
- a cranelift-native test needed an update for the new calling convention.
This bumps target-lexicon and adds support for the AppleAarch64 calling
convention. Specifically for WebAssembly support, we only have to worry
about the new stack slots convention. Stack slots don't need to be at
least 8-bytes, they can be as small as the data type's size. For
instance, if we need stack slots for (i32, i32), they can be located at
offsets (+0, +4). Note that they still need to be properly aligned on
the data type they're containing, though, so if we need stack slots for
(i32, i64), we can't start the i64 slot at the +4 offset (it must start
at the +8 offset).
Added one test that was failing on the Mac M1, as well as other tests
stressing different yet similar situations.
This commit enables Cranelift's AArch64 backend to generate code
for instruction set extensions (previously only the base Armv8-A
architecture was supported); also, it makes it possible to detect
the extensions supported by the host when JIT compiling. The new
functionality is applied to the IR instruction `AtomicCas`.

With `Module::{serialize,deserialize}` it should be possible to share
wasmtime modules across machines or CPUs. Serialization, however, embeds
a hash of all configuration values, including cranelift compilation
settings. By default wasmtime's selection of the native ISA would enable
ISA flags according to CPU features available on the host, but the same
CPU features may not be available across two machines.
This commit adds a `Config::cranelift_clear_cpu_flags` method which
allows clearing the target-specific ISA flags that are automatically
inferred by default for the native CPU. Options can then be
incrementally built back up as-desired with teh `cranelift_other_flag`
method.
cargo-deny tells us that we should upgrade raw-cpuid to v9.0.0. This
new version also seems to lack the `nightly` feature (perhaps it has
been incorporated into the base functionality) so I had to remove this
feature selector to build.
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.
* 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.
This patch updates or removes all references to the Cranelift repository. It affects links in README documents, issues that were transferred to the Wasmtime repository, CI badges, and a small bunch of sundry items.
* Bump version to 0.48.0
* Re-enable `byteorder`'s default features.
The code uses `WriteBytesExt` which depends on the `std` feature being
enabled. So for now, just enable `std`.
