This commit started off by deleting the `cranelift_codegen::settings`
reexport in the `wasmtime-environ` crate and then basically played
whack-a-mole until everything compiled again. The main result of this is
that the `wasmtime-*` family of crates have generally less of a
dependency on the `TargetIsa` trait and type from Cranelift. While the
dependency isn't entirely severed yet this is at least a significant
start.
This commit is intended to be largely refactorings, no functional
changes are intended here. The refactorings are:
* A `CompilerBuilder` trait has been added to `wasmtime_environ` which
server as an abstraction used to create compilers and configure them
in a uniform fashion. The `wasmtime::Config` type now uses this
instead of cranelift-specific settings. The `wasmtime-jit` crate
exports the ability to create a compiler builder from a
`CompilationStrategy`, which only works for Cranelift right now. In a
cranelift-less build of Wasmtime this is expected to return a trait
object that fails all requests to compile.
* The `Compiler` trait in the `wasmtime_environ` crate has been souped
up with a number of methods that Wasmtime and other crates needed.
* The `wasmtime-debug` crate is now moved entirely behind the
`wasmtime-cranelift` crate.
* The `wasmtime-cranelift` crate is now only depended on by the
`wasmtime-jit` crate.
* Wasm types in `cranelift-wasm` no longer contain their IR type,
instead they only contain the `WasmType`. This is required to get
everything to align correctly but will also be required in a future
refactoring where the types used by `cranelift-wasm` will be extracted
to a separate crate.
* I moved around a fair bit of code in `wasmtime-cranelift`.
* Some gdb-specific jit-specific code has moved from `wasmtime-debug` to
`wasmtime-jit`.
* Start a high-level architecture document for Wasmtime
This commit cleands up some existing documentation by removing a number
of "noop README files" and starting a high-level overview of the
architecture of Wasmtime. I've placed this documentation under the
contributing section of the book since it seems most useful for possible
contributors.
I've surely left some things out in this pass, and am happy to add more!
* Review comments
* More rewording
* typos
* Upgrade to the latest versions of gimli, addr2line, object
And adapt to API changes. New gimli supports wasm dwarf, resulting in
some simplifications in the debug crate.
* upgrade gimli usage in linux-specific profiling too
* Add "continue" statement after interpreting a wasm local dwarf opcode
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 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.
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 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.
* 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.
* Remove usage of `CompilationStrategy` from `Config`
This commit removes the public API usage of the internal
`CompilationStrategy` enumeration from the `Config` type in the
`wasmtime` crate. To do this the `enum` was copied locally into the
crate and renamed `Strategy`. The high-level description of this change
is:
* The `Config::strategy` method now takes a locally-defined `Strategy`
enumeration instead of an internal type.
* The contents of `Strategy` are always the same, not relying on Cargo
features to indicate which variants are present. This avoids
unnecessary downstream `#[cfg]`.
* A `lightbeam` feature was added to the `wasmtime` crate itself to
lightbeam compilation support.
* The `Config::strategy` method is now fallible. It returns a runtime
error if support for the selected strategy wasn't compiled in.
* The `Strategy` enum is listed as `#[non_exhaustive]` so we can safely
add variants over time to it.
This reduces the public crate dependencies of the `wasmtime` crate
itself, removing the need to reach into internal crates even more!
cc #708
* Fix fuzz targets
* Update nightly used to build releases
* Run rustfmt
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.
