@WG-prioritization issue #72343 has been requested for prioritization.
Let's tag as
E-needs-bisection and ping the LLVM-ICE-breakers?
I'm going over
this one is pending
but seems like an LLVM issue
Hanna Kruppe did some investigation
We could try filing an LLVM bug report but tbh I'm pessimistic about how easy it is to fix this and how important such a fix would be, realistically speaking. (Is this example distilled from a more realistic program? Does the redundant test cause a measurable performance problem there?)
based on that and a later comment is why I'm saying
I agree, it's been there for a long time and it's probably not really actionable on our part
Issue #72343's prioritization request has been removed.
