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