On a high level, the role of the object writer is to go over all the marked `ObjectNode`s in the graph, retrieve their data, defined symbols, and relocations to other symbols, and store them in the object file.
NativeAOT compiler contains multiple object writers:
-* Native object writer (`src/coreclr/tools/aot/ObjWriter`) based on LLVM that is capable of producing Windows PE, Linux ELF, and macOS Mach-O file formats
+* Native object writer based on LLVM that is capable of producing Windows PE, Linux ELF, and macOS Mach-O file formats
* Native object writer based on LLVM for WebAssembly
* Ready to run object writer that generates mixed CIL/native executables in the ready to run format for CoreCLR
- [NOT PORTED OVER YET] The build will place the toolchain packages at `artifacts\packages\[Debug|Release]\Shipping`. To publish your project using these packages:
- [NOT PORTED OVER YET] Add the package directory to your `nuget.config` file. For example, replace `dotnet-experimental` line in `samples\HelloWorld\nuget.config` with `<add key="local" value="C:\runtimelab\artifacts\packages\Debug\Shipping" />`
- [NOT PORTED OVER YET] 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.
-- *Optional*. The ObjWriter component of the AOT compiler is not built by default. 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 run `build[.cmd|.sh] clr.objwriter` from the repo root before building the product.
+- 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 repo (branch 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 ILC compiler typically compiles the whole program - it loosely corresponds to the composite mode of crossgen2. There is a multifile mode, where each managed assembly corresponds to a single object file, but this mode is not shipping.
-- The object files generated by the ILC compiler are written out using an LLVM-based object writer (src\coreclr\tools\aot\ObjWriter). The object writer uses the LLVM assembler APIs (APIs meant to be used by tools that convert textual assembly into machine code) to emit object files in PE/ELF/Mach-O formats. Normally the object writer is not built as part of the repo, but gets downloaded through NuGet. If you need to debug the object writer, you can build it by specifying `clr.objwriter` subset to the root build script. It takes about 5 minutes to compile the object writer.

-# Native Object Writer library
-
-This directory contains a native object file writer library based on LLVM. This library exposes C APIs to emit ELF/Mach-O/PE object files.
-
-The implementation is based on LLVM's assembler APIs - these are APIs intended to be consumed by assembly language compilers and are therefore close to the underlying object file formats. When in doubt, look at how the assemblers (e.g. llvm-ml in the tools directory of LLVM) use these APIs.
-
-The build script clones the appropriate version of the LLVM source tree, applies a patch that adds a couple of things we need, and builds the repo with this directory added as an out-of-tree tool.
