## Building and testing
```bash
-$ git clone https://github.com/bjorn3/rustc_codegen_cranelift.git
+$ git clone https://github.com/bjorn3/rustc_codegen_cranelift
$ cd rustc_codegen_cranelift
-$ ./y.rs prepare # download and patch sysroot src and install hyperfine for benchmarking
+$ ./y.rs prepare
$ ./y.rs build
```
$ ./test.sh
```
-This will implicitly build cg_clif too. Both `y.rs build` and `test.sh` accept a `--debug` argument to
-build in debug mode.
+For more docs on how to build and test see [build_system/usage.txt](build_system/usage.txt) or the help message of `./y.rs`.
-Alternatively you can download a pre built version from [GHA]. It is listed in the artifacts section
+Alternatively you can download a pre built version from [Github Actions]. It is listed in the artifacts section
of workflow runs. Unfortunately due to GHA restrictions you need to be logged in to access it.

## Usage
* Inline assembly ([no cranelift support](https://github.com/bytecodealliance/wasmtime/issues/1041))
* On UNIX there is support for invoking an external assembler for `global_asm!` and `asm!`.
-* SIMD ([tracked here](https://github.com/bjorn3/rustc_codegen_cranelift/issues/171), some basic things work)
+* SIMD ([tracked here](https://github.com/bjorn3/rustc_codegen_cranelift/issues/171), `std::simd` fully works, `std::arch` is partially supported)
+* Unwinding on panics ([no cranelift support](https://github.com/bytecodealliance/wasmtime/issues/1677), `-Cpanic=abort` is enabled by default)

-
-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]
-
-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.
-
- --no-unstable-features
- fSome features are not yet ready for production usage. This option will disable these
- features. This includes the JIT mode and inline assembly support.

--- /dev/null
+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`.
