|
|
./y.sh test [--sysroot none|clif|llvm] [--out-dir DIR] [--download-dir DIR] [--no-unstable-features] [--frozen] [--skip-test TESTNAME]

OPTIONS:
|
|
--sysroot none|clif|llvm
|
|
Which sysroot libraries to use:
|
|
`none` will not include any standard library in the sysroot.
|
|
`clif` will build the standard library using Cranelift.
|
|
`llvm` will use the pre-compiled standard library of rustc which is compiled with LLVM.
|
|
|
|
--out-dir DIR
|
|
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
|
|

REQUIREMENTS:
|
|
* 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: Git is used for downloading test repos and applying patches.
|
|
* [Hyperfine](https://github.com/sharkdp/hyperfine/): Used for benchmarking with `./y.sh bench`.
