Phoronix: Clang'ing The Kernel With Different LLVM Setups Will Be Easier With Linux 5.18

Building the Linux kernel with LLVM/Clang rather than GCC has continued maturing nicely since the support was mainlined two years ago and additional LLVM/Clang functionality continues to be optionally supported by the Linux kernel. With Linux 5.18 there is an improvement around the handling of the LLVM environment variable for dealing with versioned compiler binaries or compiler installations outside of the PATH...

Good news. Building a ltoed Kernel with Clang leads to numerous speedups. Especially with AOCC on AMD. But at the moment it has it hickups as described by the article. Great to hear that this is going to be improved with future releases.

I've been dreaming of getting a Ryzen laptop and having a full AOCC build. (Long run, having the optimizations from AOCC in mainstream llvm/clang would be best.) For now, I think it would just be super zippy!!
