18 | # This test checks the behavior of formatted print when applied to a | |
19 | # reference value. The intended behavior is that a formatted print of | |
20 | # such a value should display the same value as a plain print, | |
21 | # modulo format, of course. Older versions of GDB would instead print | |
22 | # the reference's address value itself when doing a formatted print, | |
23 | # rather than printing both that and the dereferenced value. We also | |
24 | # check that the (non-standard) expression &(&x), where x is of type T&, | |
25 | # yields an appropriate value. | |

26 | # This also tests that some other arithmetic operations on references |
27 | # work properly: condition expression using a reference object as one of its | |
28 | # operand. | |
