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

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