+@kindex -z memtag-mode=@var{mode}
+@cindex MTE modes of operation
+The @samp{-z memtag-mode=mode} specifies the MTE mode of operation.
+The value of @samp{mode} can be one of @samp{none}, @samp{sync} or
+@samp{async}.  The specified modes determine the value of the
+@samp{DT_AARCH64_MEMTAG_MODE} dynamic tag.  The @samp{sync} mode
+implies precise exceptions, with the runtime providing the exact
+instruction where the fault occurred, and the exact faulting address.
+The @samp{async} mode implies imprecise exceptions.

+@kindex -z memtag-stack
+@cindex Mark program stack for MTE protection
+The @samp{-z memtag-stack} specifies that output object uses MTE
+instructions for stack memory usage.
