+<p>This box indicates whether the target supports segmented stacks. This
+replaces the traditional large C stack with many linked segments. It
+is compatible with the <a href="http://gcc.gnu.org/wiki/SplitStacks">gcc
+implementation</a> used by the Go front end.</p>
+
+<p id="feat_segstacks_x86">Basic support exits on the X86 backend. Currently
+vararg don't work and the object files are not marked the way the gold
+linker expects, but simple Go program can be built by dragonegg.</p>
