You can now use `build.[cmd|sh] clr.aot` to build the components for the AOT workloads.
The Native AOT toolchain can be currently built for Linux (x64/arm64), macOS (x64) and Windows (x64/arm64).
+## Building
+
+1. [Install pre-requisites](../../README.md#build-requirements)
+1. Run `build[.cmd|.sh] clr.aot+libs -rc [Debug|Release]` from the repo root to build binaries for local development. This will build individual components, but not the NuGet packages and builds much faster.
+
+### Using built binaries
+
+The paths to major components can be overridden using `IlcToolsPath`, `IlcSdkPath`, `IlcFrameworkPath`, `IlcFrameworkNativePath` and `IlcMibcPath` properties for `dotnet publish`. For example, `/p:IlcToolsPath=<repo root>\artifacts\bin\coreclr\windows.x64.Debug\ilc` can be used to override the compiler with a local debug build for troubleshooting or quick iterations.
+
+The component that writes out object files (objwriter.dll/libobjwriter.so/libobjwriter.dylib) is based on LLVM and doesn't build in the runtime repo. It gets published as a NuGet package out of the [dotnet/llvm-project](https://github.com/dotnet/llvm-project) repo (branch [objwriter/12.x](https://github.com/dotnet/llvm-project/tree/objwriter/12.x)). If you're working on ObjWriter or bringing up a new platform that doesn't have ObjWriter packages yet, as additional pre-requisites you need to build objwriter out of that repo and replace the file in the output.
+
+### Building packages
+
+Run `build[.cmd|.sh] -c Release` from the repo root to build the NativeAOT toolchain packages. The build will place the toolchain packages at `artifacts\packages\Release\Shipping`. To publish your project using these packages:
+ - Add the package directory to your `nuget.config` file. For example, add `<add key="local" value="C:\runtime\artifacts\packages\Release\Shipping" />`
+ - Run `dotnet publish --packages pkg -r [win-x64|linux-x64|osx-64] -c [Debug|Release]` to publish your project. `--packages pkg` option restores the package into a local directory that is easy to cleanup once you are done. It avoids polluting the global nuget cache with your locally built dev package.

## High Level Overview
Native AOT is a stripped down version of the CoreCLR runtime specialized for ahead of time compilation, with an accompanying ahead of time compiler.
The compiler also has a mode where each managed assembly can be compiled into a separate object file. The object files are later linked into a single executable using the platform linker. This mode is mostly used in testing (it's faster to compile this way because we don't need to recompiling the same code from e.g. CoreLib). It's not a shipping configuration and has many problems (requires exactly matching compilation settings, forfeits many optimizations, and has trouble around cross-module generic virtual method implementations).
-## Building
-
-- [Install pre-requisites](../../README.md#build-requirements)
-- Run `build[.cmd|.sh] -c Release` from the repo root to build the NativeAOT toolchain packages. The build will place the toolchain packages at `artifacts\packages\Release\Shipping`. To publish your project using these packages:
- - Add the package directory to your `nuget.config` file. For example, add `<add key="local" value="C:\runtime\artifacts\packages\Release\Shipping" />`
- - Run `dotnet publish --packages pkg -r [win-x64|linux-x64|osx-64] -c [Debug|Release]` to publish your project. `--packages pkg` option restores the package into a local directory that is easy to cleanup once you are done. It avoids polluting the global nuget cache with your locally built dev package.
-- The toolchain packages are not required for day to day development. Run `build[.cmd|.sh] clr+libs -rc [Debug|Release] -lc Release` from the repo root to build just the parts of the repo required for general CoreCLR development. Alternatively, instead of specifying `clr+libs`, you can specify `clr.alljits+clr.tools+clr.nativeaotlibs+clr.nativeaotruntime+libs` which is more targeted and builds faster.
-- The paths to major components can be overriden using `IlcToolsPath`, `IlcSdkPath`, `IlcFrameworkPath`, `IlcFrameworkNativePath` and `IlcMibcPath` properties for `dotnet publish`. For example, `/p:IlcToolsPath=<repo root>\artifacts\bin\coreclr\windows.x64.Debug\ilc` can be used to override the compiler with a local debug build for troubleshooting or quick iterations.
-- The component that writes out object files (objwriter.dll/libobjwriter.so/libobjwriter.dylib) is based on LLVM and doesn't build in the runtime repo. It gets published as a NuGet package out of the [dotnet/llvm-project](https://github.com/dotnet/llvm-project) repo (branch [objwriter/12.x](https://github.com/dotnet/llvm-project/tree/objwriter/12.x)). If you're working on ObjWriter or bringing up a new platform that doesn't have ObjWriter packages yet, as additional pre-requiresites you need to build objwriter out of that repo and replace the file in the output.

## Visual Studio Solutions
The repository has a number of Visual Studio Solutions files (`*.sln`) that are useful for editing parts of the repository. Build the repo from command line first before building using the solution files. Remember to select the appropriate configuration that you built. By default, `build.cmd` builds Debug x64 and so `Debug` and `x64` must be selected in the solution build configuration drop downs.
For more advanced scenarios, look for at [Building Test Subsets](../../testing/coreclr/windows-test-instructions.md#building-test-subsets) and [Generating Core_Root](../../testing/coreclr/windows-test-instructions.md#generating-core_root)
### Running library tests
-Build library tests by passing the `libs.tests` subset together with the `/p:TestNativeAot=true` to build the libraries, i.e. `clr.alljits+clr.tools+clr.nativeaotlibs+clr.nativeaotruntime+libs+libs.tests /p:TestNativeAot=true` together with the full arguments as specified [above](#building). Then, to run a specific library, go to the tests directory of the library and run the usual command to run tests for the library (see [Running tests for a single library](../../testing/libraries/testing.md#running-tests-for-a-single-library)) but add the `/p:TestNativeAot=true` and the build configuration that was used, i.e. `dotnet.cmd build /t:Test /p:TestNativeAot=true -c Release`.
