Hi,

I'm doubtful that tracking development branches of LLVM is a good
investment. Their development model is to do changes in-tree much more than we
do. Adjusting to API changes the moment they're made will often end up with
further changes to the same / related lines. Once they open the relevant
release-NN branch, it's a different story.

Maybe it'd make sense to disable --with-llvm on seawasp and have a separate
animal that tracks the newest release branch?

Greetings,

Andres Freund
