Another situation where it's helpful to show symbol filenames and line

numbers is when disassembling code; @value{GDBN} will show you the line

number and source file that corresponds to each instruction.
|

|

If you have a pointer and you aren't sure what object it points to,
|
||||
you can turn on printing of symbolic addresses and filenames, and
|
||||
determine the name and source file location of the variable which
|
||||
is being pointed to, using the @code{x/x @var{pointer}} command.
|
||||
This displays the memory location pointed to, and as a side effect,
|
||||
interprets the address in symbolic form.
|
||||
|

Also, you may wish to see the symbolic form only if the address being
|

printed is reasonably close to the closest earlier symbol:

Sometimes @value{GDBN} can tell you more about an address if it does an

a quick symbolic display that is usually correct, but which may not give
