It does. I did test before using $ cd /usr/src/sys/boot $ env -i __MAKE_CONF= PATH=/bin:/sbin:/usr/bin:/usr/sbin make CC=clang $ make install <wait a bit for data to sync> $ sudo qemu-system-x86_64 -curses -drive file=/dev/ada0 -drive file=/dev/ada1 In gcc -O0 case $ touch zfs/zfs.c $ rm i386/zfsloader/zfsloader* $ echo CFLAGS+=-O0 >>zfs/Makefile $ env -i ... make CC=gcc And for gcc47 $ touch zfs/zfs.c $ rm i386/zfsloader/zfsloader* $ env -i ... make CC=/usr/local/bin/gcc47 -C zfs I haven't tried to further track down which flag(s) within -O1 make zfsloader from your branch work when compiled with base gcc.Received on Mon Jul 02 2012 - 08:55:49 UTC
