# This test checks the behavior of formatted print when applied to a
|
|
# reference value. The intended behavior is that a formatted print of
|
|
# such a value should display the same value as a plain print,
|
|
# modulo format, of course. Older versions of GDB would instead print
|
|
# the reference's address value itself when doing a formatted print,
|
|
# rather than printing both that and the dereferenced value. We also
|
|
# check that the (non-standard) expression &(&x), where x is of type T&,
|
|
# yields an appropriate value.
|
|
# This also tests that some other arithmetic operations on references
|
|
# work properly: condition expression using a reference object as one of its
|
|
# operand.
