--- Comment #7 from Ed Schouten <ed at 80386.nl> ---
Reopening this, as it has not been implemented completely.

The problem with the existing implementation is that __start and __stop symbols
are only added after reachability of sections has been computed. What I mean is
that __start and __stop cannot be used to mark sections as live. They will get
removed if --gc-sections is being used.

This is different from GNU Binutils, were a reference to __start or __stop is
sufficient to prevent the section from being garbage collected.
