# "all". This is required since the set of targets built by "all" is determined
# automatically based on reachability from the root BUILD.gn (for details, see
# crbug.com/503241). Builders should typically use "all", or list targets
# explicitly, rather than relying on "gn_all".
#
# "gn_visibility": targets that are normally not visible to top-level targets,
# but are built anyway by "all". Since we don't want any such targets, we have
# this placeholder to make sure hidden targets that aren't otherwise depended
# on yet are accounted for.
