  18 # Note: This test is essentially a transcription of gdb.cp/formatted-ref.exp,
  19 # and is thus much more wordy than it needs to be. There are fewer
  20 # tests because only a few parameter types in Ada are required to be
  21 # passed by reference, and there is no equivalent of &(&x) for reference
  22 # values.
  23 # This also tests that some other arithmetic operations on references
  24 # work properly: condition expression using a reference object as one of its
  25 # operand.
