       addr2line - convert addresses into file names and line numbers.

       addr2line [-a|--addresses]
                 [-b bfdname|--target=bfdname]
                 [-e filename|--exe=filename]
                 [-f|--functions] [-s|--basename]
                 [-H|--help] [-V|--version]
                 [addr addr ...]

       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.

       The long and short forms of options, shown here as alternatives, are

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

           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
           Specify the name of the executable for which addresses should be
           translated.  The default file is a.out.

           Display function names as well as file and line number information.

           Display only the base of each file name.

           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.

           Read offsets relative to the specified section instead of absolute

           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).

           Enables or disables a limit on the amount of recursion performed
           whilst demangling strings.  Since the name mangling formats allow for
           an inifinite level of recursion it is possible to create strings
           whose decoding will exhaust the amount of stack space available on
           the host machine, triggering a memory fault.  The limit tries to
           prevent this from happening by restricting recursion to 2048 levels
           of nesting.

           The default is for this limit to be enabled, but disabling it may be
           necessary in order to demangle truly complicated names.  Note however
           that if the recursion limit is disabled then stack exhaustion is
           possible and any bug reports about such an event will be rejected.

           The -r option is a synonym for the --no-recurse-limit option.  The -R
           option is a synonym for the --recurse-limit option.

           Note this option is only effective if the -C or --demangle option has
           been enabled.

           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

           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.
