How close is this to the mainline clang builds from https://apt.llvm.org/?
The last time we talked, there were still a couple of bugs that prevented me from building an unmodified kernel with an unmodified clang toolchain, but I think you planned to address those. Are any changes left that did not make it into the 12.0 release?

I'm happy to edit the index page on https://mirrors.edge.kernel.org/pub/tools/crosstool, but could you provide a stable URL that will keep pointing to the latest version in the future so I don't have to update it for each new build?
