NAME
       addr2line - convert addresses into file names and line numbers

SYNOPSIS
       addr2line
	      [-b bfdname | --target=bfdname] [-C|--demangle] [-e filename |
	      --exe=filename] [-f|--functions] [-s|--basenames] [-H|--help]
	      [-V|--version] [addraddr...]

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
       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.

OPTIONS
       -b bfdname

       --target=bfdname
	      Specify the object-code format for the object files to  be  bfd‐
	      name.

       -C

       --demangle
	      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.

       -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  informa‐
	      tion.

       -s

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