  21 # test basic Machine interface (MI) operations
  22 #
  23 # Verify that, using the MI, we can load a program and do
  24 # other basic things that are used by all test files through  mi_gdb_exit,
  25 # mi_gdb_start, mi_delete_breakpoints, mi_gdb_reinitialize_dir and
  26 # mi_gdb_load, so we can safely use those.
  27 #
  28 # The goal is not to test gdb functionality, which is done by other tests,
  29 # but the command syntax and correct output response to MI operations.
