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]
		 [-i|--inlines]
		 [-j|--section=name]
		 [-H|--help] [-V|--version]
		 [addr addr ...]

DESCRIPTION
       addr2line translates addresses into file names and line numbers.  Given
       an address in an executable or an offset in a section of a  relocatable
       object, it uses the debugging information to figure out which file name
       and line number are associated with it.

       The executable or relocatable object to use is specified  with  the  -e
       option.	The default is the file a.out.	The section in the relocatable
       object to use is specified with the -j option.

       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.

       -i
       --inlines
	   If the address belongs to a function that was inlined,  the	source
	   information	for all enclosing scopes back to the first non-inlined
	   function will also be printed.   For  example,  if  "main"  inlines
	   "callee1"  which  inlines "callee2", and address is from "callee2",
	   the source information  for	"callee1"  and	"main"	will  also  be
	   printed.

       -j
       --section
	   Read  offsets relative to the specified section instead of absolute
	   addresses.

       @file
	   Read command-line options from file.  The options read are inserted
	   in  place of the original @file option.  If file does not exist, or
	   cannot be read, then the option will be treated literally, and  not
	   removed.

	   Options  in file are separated by whitespace.  A whitespace charac
	   ter may be included in an option by surrounding the	entire	option
	   in  either  single  or  double  quotes.  Any character (including a
	   backslash) may  be  included  by  prefixing	the  character	to  be
	   included  with a backslash.	The file may itself contain additional
	   @file options; any such options will be processed recursively.
