Thank you for reply.
I was compiling without special options.
% cd /usr/src
(/usr/src -> nfsserver:/usr/altlocal/freebsd-current/src)
% svn up
% time sh -c 'make -j4 buildworld && make -j4 buildkernel'
(nfs connection was stalled. So I rebooted machine and re-makeworld as follows)
% su
# reboot
% cd /usr/src
% time sh -c 'make -j4 buildworld && make -j4 buildkernel'
% su
# make installkernel
# reboot
# cd /usr/src
# make installworld
(Broked userland was installed.)
# mergemaster -Ui
# make check-old
# make BATCH_DELETE_OLD_FILES=yes delete-old
# make check-old-libs
# make BATCH_DELETE_OLD_FILES=yes delete-old-libs
# pkg upgrade
# reboot
(I can not make buildworld with the libunwind: decodeEHHdr error.)
I did rebuild kernel and userland with another machine and
reinstall kernel/userland to the broken machines. Now they
are working well.
P.S. Althougth I was applied patches of https://reviews.llvm.org/D57081,
no libunwind: decodeEHHdr messages are displayed. I think D57081 is
not cause of this.
