$ sgit grep external-pass-pipeline-filename
include/swift/Option/FrontendOptions.td:def external_pass_pipeline_filename : Separate<["-"], "external-pass-pipeline-filename">,
utils/pass-pipeline/scripts/pipelines_build_script.py:        '-external-pass-pipeline-filename\;-Xfrontend\;%s' % data_file]
