## Precompiled builds
Alternatively you can download a pre built version from the [releases] page.
Extract the `dist` directory in the archive anywhere you want.
If you want to use `cargo clif build` instead of having to specify the full path to the `cargo-clif` executable, you can add the `bin` subdirectory of the extracted `dist` directory to your `PATH`.

Specify the directory in which the download, build and dist directories are stored.
By default this is the working directory.
--download-dir DIR
Specify the directory in which the download directory is stored. Overrides --out-dir.
--no-unstable-features
Some features are not yet ready for production usage. This option will disable these
features. This includes the JIT mode and inline assembly support.
--frozen
Require Cargo.lock and cache are up to date
--skip-test TESTNAME
Skip testing the TESTNAME test. The test name format is the same as config.txt.
--use-backend NAME
Use the existing Cranelift (or other) backend of the rustc with which we built.
Warning: This is meant for use in rust's CI only!
REQUIREMENTS:
* Rustup: The build system has a hard coded dependency on rustup to install the right nightly
version and make sure it is used where necessary.
* Git: `./y.rs prepare` uses git for applying patches and on Windows for downloading test repos.
* Curl and tar (non-Windows only): Used by `./y.rs prepare` to download a single commit for
* Rustup: By default rustup is used to install the right nightly version. If you don't want to
use rustup, you can manually install the nightly version indicated by rust-toolchain.toml and
point the CARGO, RUSTC and RUSTDOC env vars to the right executables.
* Git: `./y.sh prepare` uses git for applying patches and on Windows for downloading test repos.
* Curl and tar (non-Windows only): Used by `./y.sh prepare` to download a single commit for
repos. Git will be used to clone the whole repo when using Windows.
* [Hyperfine](https://github.com/sharkdp/hyperfine/): Used for benchmarking with `./y.rs bench`.
* [Hyperfine](https://github.com/sharkdp/hyperfine/): Used for benchmarking with `./y.sh bench`.
