+@item --defined-only
+@cindex external symbols
+@cindex undefined symbols
+Display only defined symbols for each object file.
+
+@item --plugin @var{name}
+@cindex load plugin
+Load the plugin called @var{name} to add support for extra target
+types. This option is only available if the toolchain has been built
+with plugin support enabled.
+
+@item --size-sort
+Sort symbols by size. The size is computed as the difference between
+the value of the symbol and the value of the symbol with the next higher
+value. If the @code{bsd} output format is used the size of the symbol
+is printed, rather than the value, and @samp{-S} must be used in order
+both size and value to be printed.
+
+@item --special-syms
+Display symbols which have a target-specific special meaning. These
+symbols are usually used by the target for some special processing and
+are not normally helpful when included in the normal symbol lists.
+For example for ARM targets this option would skip the mapping symbols
+used to mark transitions between ARM code, THUMB code and data.
+
+@item --synthetic
+Include synthetic symbols in the output. These are special symbols
+created by the linker for various purposes. They are not shown by
+default since they are not part of the binary's original source code.
+
+@item --target=@var{bfdname}
+@cindex object code format
+Specify an object code format other than your system's default format.
+@xref{Target Selection}, for more information.
