  # This job has been copied from the one above it, and modified to only build CBMC
  # and run the `regression/cbmc/` regression tests against Z3. The rest of the tests
  # (unit/regression) have been stripped based on the rationale that they are going
  # to be run by the job above, which is basically the same, but more comprehensive.
  # The reason we opted for a new job is that adding a `test-z3` step to the current
  # jobs increases the job runtime to unacceptable levels (over 2hrs).
  # This job takes approximately 3 to 18 minutes
