For the ones feeling adventurous, highly experimental, it might break from time to time: mesa-git built against llvm-git at regular intervals, can be found here
There was an issue with copr not being able to build 32bit packages for rawhide. The issue was fixed today. You’ll have to wait a bit until it will be rebuilt and available for rawhide.
Mesa aco sources haven’t been modified anyway. So whatever version you already have installed, the chances are big that you already have the latest.
Ok, for now, I am could to upgrade llvm but for doing this first I had to remove pocl package.
I thought you should restore the section "Important for distribution upgrades or first time installs" which exists in original che/mesa corp
