- * Macros for manipulating "link sets". Link sets are arrays of pointers
- * to objects, which are gathered up by the linker.
- *
- * Object format-specific code has provided us with the following macros:
- *
- * __link_set_add_text(set, sym)
- * Add a reference to the .text symbol `sym' to `set'.
- *
- * __link_set_add_rodata(set, sym)
- * Add a reference to the .rodata symbol `sym' to `set'.
- *
- * __link_set_add_data(set, sym)
- * Add a reference to the .data symbol `sym' to `set'.
- *
- * __link_set_add_bss(set, sym)
- * Add a reference to the .bss symbol `sym' to `set'.
- *
- * __link_set_decl(set, ptype)
- * Provide an extern declaration of the set `set', which
- * contains an array of the pointer type `ptype'. This
- * macro must be used by any code which wishes to reference
- * the elements of a link set.
- *
- * __link_set_start(set)
- * This points to the first slot in the link set.
- *
- * __link_set_end(set)
- * This points to the (non-existent) slot after the last
- * entry in the link set.
- *
- * __link_set_count(set)
- * Count the number of entries in link set `set'.
- *
- * In addition, we provide the following macros for accessing link sets:
- *
- * __link_set_foreach(pvar, set)
- * Iterate over the link set `set'. Because a link set is
- * an array of pointers, pvar must be declared as "type **pvar",
- * and the actual entry accessed as "*pvar".
- *
- * __link_set_entry(set, idx)
- * Access the link set entry at index `idx' from set `set'.
