I figure it’s one way to keep your compiler version unchanged for eBPF work, while you might update/upgrade your dev OS packages over time for other reasons. The title of the linked issue is this:
“Checksum code does not work for LLVM-14, but it works for LLVM-13”
Newer compilers might use new optimizations that the verifier won’t be happy with. I guess the other option would be to find some config option to disable that specific incompatible optimization.
