<pre>GNU ld supports the magic __start and __stop symbols as markers for the
beginning/end of sections. For example:
int var1 __attribute__((__section__("foo")));
int var2 __attribute__((__section__("foo")));
extern int __start_foo[0];
extern int __stop_foo[0];
GNU ld automatically adds these symbols if undefined. They will point to the
beginning/end of the section "foo". Couple of important things to keep in mind
when implementing this:
- Don't let --gc-sections reap these sections if __start_foo and __stop_foo are
being used.
- Don't inject these symbols if the section itself does not exist.
GNU ld also doesn't do this.</pre>
