+@item noextern-protected-data
+Don't treat protected data symbols as external when building a shared
+library. This option overrides the linker backend default. It can be
+used to work around incorrect relocations against protected data symbols
+generated by compiler. Updates on protected data symbols by another
+module aren't visible to the resulting shared library. Supported for
+i386 and x86-64.
-@item norelro
-Don't create an ELF @code{PT_GNU_RELRO} segment header in the object.

+overflow at run-time. Supported for x86_64.
@item now
When generating an executable or shared library, mark it to tell the
dynamic linker to resolve all symbols when the program is started, or

-Marks the object may contain $ORIGIN.
+Specify that the object requires @samp{$ORIGIN} handling in paths.
@item relro
