Prebuilt LLVM 21.1.5 uploaded

[Nathan Chancellor]

Hi all,

I have built and uploaded LLVM 21.1.5 to
https://mirrors.edge.kernel.org/pub/tools/llvm/.

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 before the 21.x
series is no longer supported.

Cheers,
Nathan

Rust-enabled x86_64 with upstream `rustc` works well:

Tested-by: Miguel Ojeda <ojeda@kernel.org>

Thanks as usual!

By the way, not sure if there is a reason for it (e.g. a workaround
for a bug or you don't keep the old LLVM files etc.), but just in
case: the matching LLVM for Rust 1.91.0 (and likely the upcoming
1.91.1) is 21.1.2 from what I can see, not 21.1.3 in the table.

Cheers,
Miguel

Ah, I think that probably came from me looking at the tip of
rustc/21.1-2025-08-01 in https://github.com/rust-lang/llvm-project and
assuming that is what rust 1.91.0 shipped with but I forgot that 'rustc
--version --verbose' will show me that :)

If 1.91.1 is coming soon, I will wait to fix this until then.

Cheers,
Nathan

Yeah, no worries at all, it should be out soon -- thanks a lot for the
quick reply!

Cheers,
