I'm still not completely happy with this; see #136603 for my most recent commentary on producing warnings based on compiler optimizations.  (That's not BPF, but under the proposal here, a similar construct compiled to BPF would produce a BPF verifier error.)  But Linux kernel developers have a different perspective on how a compiler should work... I'm not sure how to bridge the gap.
