Yeah, I linked to it: https://github.com/rust-lang/rust/issues/121889.

I'm not a linker expert, but it seems that now symlinks are required to link against the LLVM .so file, but we can't ship symlinks in our artifacts because of Windows. The old approach we used of just shipping the .so file and pointing the linker at it doesn't seem to work any more with the new sonames. I don't claim to understand why, I am involved solely because my tool no longer builds after rustc updated to LLVM 18 rc4.
