       addr2line - convert addresses into file names and line numbers.

       addr2line [-b bfdname|--target=bfdname]
                 [-e filename|--exe=filename]
                 [-f|--functions] [-s|--basename]
                 [-H|--help] [-V|--version]
                 [addr addr ...]

       addr2line  translates  program addresses into file names and line num-
       bers.  Given an address and  an  executable,  it  uses  the  debugging
       information  in  the executable to figure out which file name and line
       number are associated with a given address.

       The executable to use is specified with the -e option.  The default is
       the file a.out.

       addr2line has two modes of operation.

       In the first, hexadecimal addresses are specified on the command line,
       and addr2line displays the file name and line number for each address.

       In  the  second,  addr2line  reads hexadecimal addresses from standard
       input, and prints the file name and line number for  each  address  on
       standard  output.   In  this  mode, addr2line may be used in a pipe to
       convert dynamically chosen addresses.

       The format of the output is FILENAME:LINENO.  The file name  and  line
       number  for  each  address  is  printed on a separate line.  If the -f
       option is used, then each FILENAME:LINENO line is preceded by a  FUNC-
       TIONNAME  line  which  is  the  name  of  the  function containing the

       If the file name or function name can  not  be  determined,  addr2line
       will  print two question marks in their place.  If the line number can
       not be determined, addr2line will print 0.

       The long and short forms of options, shown here as  alternatives,  are

       -b bfdname
           Specify  that  the object-code format for the object files is bfd-

           Decode (demangle) low-level symbol names  into  user-level  names.
           Besides  removing  any initial underscore prepended by the system,
           this makes C++ function names readable.  Different compilers  have
           different  mangling styles. The optional demangling style argument
           can be used to choose an appropriate  demangling  style  for  your

       -e filename
           Specify  the  name of the executable for which addresses should be
           translated.  The default file is a.out.

           Display function names as well as file and  line  number  informa-

           Display only the base of each file name.
