> Hi @fhahn, do you have any plans to work on this PR in the near future? I'm just asking because you suggested I hold off #133099 (enabling auto-vectorisation of loops with uncountable early exits by default) until this PR has landed. It would be nice to get the uncountable early exit work more widely tested by being enabled, since at the moment we're relying solely upon the LLVM IR tests.

Ah yes, thanks for the reminder, this dropped off my radar. Will try to update it this week.
