          # A full build of llvm, clang, lld, and lldb takes about 250MB

          # builds.  Also, there is an overall 10GB cache limit, and each
          # run creates a new cache entry so we want to ensure that we have
          # enough cache space for all the tests to run at once and still
          # fit under the 10 GB limit.
