--- Comment #4 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
-Wclobbered properly warns here (and it's part of -Wextra).
With explicit -fschedule-insns, reproducible on x86 as well.
The reason for the issue is quite surprising though, I did not expect pre-RA
scheduling to lift assignments to pseudos across calls, because it just
increases register pressure at the point of the call for little or no gain.
