The build system of cg_clif.
USAGE:
./y.rs prepare [--out-dir DIR]
./y.rs build [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
./y.rs test [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
./y.rs abi-cafe [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
./y.rs bench [--debug] [--sysroot none|clif|llvm] [--out-dir DIR] [--no-unstable-features]
OPTIONS:
--debug
Build cg_clif and the standard library in debug mode rather than release mode.
Warning: An unoptimized cg_clif is very slow.
--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.
--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.
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
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`.
