Subject: Prebuilt LLVM 22.1.0-rc3 uploaded

Hi all,

I have built and uploaded LLVM 22.1.0-rc3 to
https://mirrors.edge.kernel.org/pub/tools/llvm/.

This is a prerelease version of LLVM, similar to how the Linux kernel
release candidates work. If there are any issues found, please let us
know via email or https://github.com/ClangBuiltLinux/linux/issues/new,
so that we have an opportunity to get them fixed in main and backported
to the 22.x branch before 22.1.0 is officially released. This is expected
to be the final 22.1.0 release candidate, with 21.1.0 final expected on
February 24th.

You may notice that these packages use ~35% less disk space than previous
22.1.0-rc packages. I have switched to LLVM's multicall binary option,
similar to busybox, which allows much more code (namely internal LLVM
libraries) to be shared between the various tools without being
dynamically linked (which has a noticeable performance penalty [1]).
There should be no noticeable differences with this mode at runtime (at
least when building the kernel) but if there are, please let me know.

Cheers,
