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.
