hi there,
i think the following warnings were discussed once before:
In file included from
/usr/git-freebsd-head/sys/dev/ath/ath_hal/ah_regdomain.c:99:
/usr/git-freebsd-head/sys/dev/ath/ath_hal/ah_regdomain/ah_rd_domains.h:69:15:

iirc, back then, it was labeled as a clang bug. however testing with clang tot,
i still get those warnings. so i just wanted to ask again, whether the warnings
are really bogus, or if these warnings actually indicate issues during
shifting?
cheers.
