Here is the command I use (where target is @system @world) (somebody
once said here it can be useful to first do @system):

time emerge \
     $pretend \
     -v \
     --deep \
     --update \
     --changed-use \
     --verbose-conflicts \
     --keep-going \
     --with-bdeps=y \
     --changed-deps \
     --backtrack=100 \
     $target
