+@subsection Options specific to C6X uClinux targets
+
+@c man begin OPTIONS
+
+The C6X uClinux target uses a binary format called DSBT to support shared
+libraries.  Each shared library in the system needs to have a unique index;
+all executables use an index of 0.
+
+@table @gcctabopt
+
+@kindex --dsbt-size
+@item --dsbt-size @var{size}
+This option sets the number of entires in the DSBT of the current executable
+or shared library to @var{size}.  The default is to create a table with 64
+entries.
+
+@kindex --dsbt-index
+@item --dsbt-index @var{index}
+This option sets the DSBT index of the current executable or shared library
+to @var{index}.  The default is 0, which is appropriate for generating
+executables.  If a shared library is generated with a DSBT index of 0, the
+@code{R_C6000_DSBT_INDEX} relocs are copied into the output file.
