# We only have libfuzzer in Chromium builds but if we build fuzzer targets only
# there, we would risk breaking fuzzer targets all the time when making changes
# to Dawn. To avoid that, we make fuzzer targets compile in standalone builds
# as well with a dawn_fuzzer_test target that acts like Chromium's fuzzer_test.
#
# The standalone fuzzer targets are able to run a single fuzzer input which
# could help reproduce fuzzer crashes more easily because you don't need a
# whole Chromium checkout.
