Before this patch, running the x64 new backend would require both
compiling with --features experimental_x64 and running with
`use_new_backend`.
This patches changes this behavior so that the runtime flag is not
needed anymore: using the feature flag will enforce usage of the new
backend everywhere, making using and testing it much simpler:
cargo run --features experimental_x64 ;; other CLI options/flags
This also gives a hint at what the meta language generation would look
like after switching to the new backend.
Compiling only with the x64 codegen flag gives a nice compile time speedup.
* This PR is against a branch called `main`
* Internally all docs/CI/etc is updated
* The default branch of the repo is now `main`
* All active PRs have been updated to retarget `main`
Closes#1914
Rather than outright replacing parts of our existing peephole optimizations
passes, this makes peepmatic an optional cargo feature that can be enabled. This
allows us to take a conservative approach with enabling peepmatic everywhere,
while also allowing us to get it in-tree and make it easier to collaborate on
improving it quickly.
* 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.
Removes an edge towards the `synstructure` dependency in our dependency
graph which, if removed entirely, is hoped to reduce build times locally
and on CI as you switch between `cargo build` and `cargo test` because
deep dependencies like `syn` won't have their features alternating back
and forth.
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.
Update the documentation for the merger, and also for various changes in
Cranelift. Remove some old obsolete documentation, and convert the remaining
Sphinx files to Markdown. Some of the remaining content is still out of
date, but this is a step forward.
* All: Drop 'basic-blocks' feature
This makes it so that 'basic-blocks' cannot be disabled and we can
start assuming it everywhere.
* Tests: Replace non-bb filetests with bb version
* Tests: Adapt solver-fixedconflict filetests to use basic blocks
This commit moves the cranelift tests and tools from the `wabt` crate on
crates.io (which compiles the wabt C++ codebase) to the `wat` crate on
crates.io which is a Rust parser for the `*.wat` format. This was
motivated by me noticing that release builds on Windows are ~5 minutes
longer than Linux builds, and local timing graphs showed that `wabt-sys`
was by far the longest build step in the build process.
This commit changes the `clif-util` binary where the `--enable-simd`
flag is no longer respected with the text format as input, since the
`wat` crate has no feature gating. This was already sort of not
respected, though, since `--enable-simd` wasn't consulted for binary
inputs which `clif-util` supports as well. If this isn't ok though then
it should be ok to close this PR!
* 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`.
* the target-lexicon crate no longer has or needs the std feature
in cargo, so we can delete all default-features=false, any mentions
of its std feature, and the nostd configs in many lib.rs files
* the representation of arm architectures has changed, so some case
statements needed refactoring
