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.
