--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. The issue is that __builtin_unreachable () is 'const' while
__builtin_trap () is neither 'const' nor 'pure'. Passes inserting
__builtin_unreachable () rightfully expect 'unreachable' semantics.
IMHO changing __builtin_unreachable to __builtin_trap under-the-hood was a
very wrong thing to do.
Can we reconsider that please?
