# Description: test cases for sandbox2 unit tests.
#
# The following cc_binary options avoid dynamic linking which uses a lot of
# syscalls (open, mmap, etc.):
#   linkopts = ["-static"]
#   linkstatic = 1
#   features = ["-pie"]
# Bazel adds -pie by default but -static is incompatible with it, so we use
# the features flag to force it off.
