NAME
       addr2line - convert addresses into file names and line numbers.

SYNOPSIS
       addr2line [-b bfdname⎪--target=bfdname]
		 [-C⎪--demangle[=style]]
		 [-e filename⎪--exe=filename]
		 [-f⎪--functions] [-s⎪--basename]
		 [-H⎪--help] [-V⎪--version]
		 [addr addr ...]

DESCRIPTION
       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
       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 con‐
       vert 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 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.

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

       -b bfdname
       --target=bfdname
	   Specify  that  the  object-code format for the object files is bfd‐
	   name.

       -C
       --demangle[=style]
	   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‐
	   piler.

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

       -f
       --functions
	   Display function names as well as file and line number information.

       -s
       --basenames
	   Display only the base of each file name.
