support a similar function to export all symbols from a DLL or EXE; see
the description of @samp{--export-all-symbols} below.
+@kindex --export-dynamic-symbol=@var{glob}
+@cindex export dynamic symbol
+@item --export-dynamic-symbol=@var{glob}
+When creating a dynamically linked executable, symbols matching
+@var{glob} will be added to the dynamic symbol table. When creating a
+shared library, references to symbols matching @var{glob} will not be
+bound to the definitions within the shared library. This option is a
+no-op when creating a shared library and @samp{-Bsymbolic} or
+@samp{--dynamic-list} are not specified. This option is only meaningful
+on ELF platforms which support shared libraries.
+
+@kindex --export-dynamic-symbol-list=@var{file}
+@cindex export dynamic symbol list
+@item --export-dynamic-symbol-list=@var{file}
+Specify a @samp{--export-dynamic-symbol} for each pattern in the file.
+The format of the file is the same as the version node without
+scope and node name. See @ref{VERSION} for more information.

@kindex -Map=@var{mapfile}
@item -Map=@var{mapfile}
Print a link map to the file @var{mapfile}. See the description of the
-@option{-M} option, above. Specifying the empty string as @var{mapfile}
-(that is, @code{-Map=}) causes the link map to be written to a file
-named after the @var{output} file, with @code{.map} appended.
-Specifying a directory as @var{mapfile} causes the link map to be
-written into a file inside the directory. The name of the file is
-again based upon the @var{output} filename with @code{.map} appended.
