之前有朋友問到這個問題，是否有使用LLVM/Clang編譯Linux內核的，隨手找了一些相關資料，在這里貼出來，與大家共享。

項目簡介：

LLVMLinux Project Overview

This project aims to fully build the?Linux kernel?using?Clang?which is the C front end for the?LLVM?compiler infrastructure project. Together Clang and LLVM have many positive attributes and features which many developers and system integrators would like to take advantage of when developing and deploying the Linux Kernel as a part of their own projects.

The hope is that this project will help reduce duplicate work, as well as concentrate, and accelerate efforts around this subject matter in order to allow Linux Kernel developers, and system integrators to have the choice of a Clang compiled Linux kernel. The goal is for this project to be a testing/proving ground for these updates and to get patches that make this possible upstream to their respective projects.

The LLVMLinux project consolidates the work of the lll-project, the PAX team, and Mark Charlebois' work on the ARM kernel.

There have been several?presentations and articles?on this topic if you wish to learn more about the reasons for this project.

Currently the work is centred around the ARM, x86, x86_64, and MIPS architectures but contributions to support other architectures are welcome.?Patches accepted!

Interested parties will be holding a Bi-weekly Google Hangout to discuss project status and goals.

最新進展情況，從新聞稿中可以看出：

LLVM Clang Building?- The mainline kernel still can't build cleanly under the LLVM Clang compiler.?The LLVMLinux project slowed down a lot?but hopefully developers will get back to working on this support in the not too distant future.?

至少到2016年10月19日，該新聞發布的時候，還無法正常支持主線的內核編譯。同時，也號召有興趣的朋友們積極參與該項目。

另外，該項目的郵件列表為：?llvmlinux@lists.linuxfoundation.org.
