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

SYNOPSIS
       addr2line [-a|--addresses]
		 [-b bfdname|--target=bfdname]
		 [-C|--demangle[=style]]
		 [-e filename|--exe=filename]
		 [-f|--functions] [-s|--basename]
		 [-i|--inlines]
		 [-p|--pretty-print]
		 [-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
       convert dynamically chosen addresses.

       The format of the output	is FILENAME:LINENO.  By	default	each input
       address generates one line of output.

       Two options can generate	additional lines before	each FILENAME:LINENO
       line (in	that order).

       If the -a option	is used	then a line with the input address is
       displayed.

       If the -f option	is used, then a	line with the FUNCTIONNAME is
       displayed.  This	is the name of the function containing the address.

       One option can generate additional lines	after the FILENAME:LINENO
       line.

       If the -i option	is used	and the	code at	the given address is present
       there because of	inlining by the	compiler then additional lines are
       displayed afterwards.  One or two extra lines (if the -f	option is
       used) are displayed for each inlined function.

       Alternatively if	the -p option is used then each	input address
       generates a single, long, output	line containing	the address, the
       function	name, the file name and	the line number.  If the -i option has
       also been used then any inlined functions will be displayed in the same
       manner, but on separate lines, and prefixed by the text (inlined	by).

       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.

       -a
       --addresses
	   Display the address before the function name, file and line number
	   information.	 The address is	printed	with a 0x prefix to easily
	   identify it.

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

       -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
	   compiler.

       -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.

       -p
       --pretty-print
	   Make	the output more	human friendly:	each location are printed on
	   one line.  If option	-i is specified, lines for all enclosing
	   scopes are prefixed with (inlined by).

       @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
	   character 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.
