       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	infor-
       mation  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  in-
       put, and	prints the file	name and line number for each address on stan-
       dard 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  op-
       tion is used, then each FILENAME:LINENO line is preceded	by a FUNCTION-
       NAME line which is the name of the function containing the address.

       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 com-

       -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 information.

	   Display only	the base of each file name.

       Info entries for	binutils.
