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.  The file name and line
       number for each input address is printed on separate lines.

       If the -f option is used, then each FILENAME:LINENO line is preceded by
       FUNCTIONNAME which is the name of the function containing the address.

       If the -i option is used and the code at the given address is present
       there because of inlining by the compiler then the {FUNCTIONNAME}
       FILENAME:LINENO information for the inlining function will be displayed
       afterwards.  This continues recursively until there is no more inlining
       to report.

       If the -a option is used then the output is prefixed by the input
       address.

       If the -p option is used then the output for each input address is
       displayed on one, possibly quite long, line.  If -p is not used then
       the output is broken up into multiple lines, based on the paragraphs
       above.

       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.
