+ <li>
+ For ELF targets that support the GNU or FreeBSD OSABIs, the
+ <code>used</code> attribute will now save the symbol declaration it is
+ applied to from linker garbage collection.
+ <br>
+ To support this behavior, <code>used</code> symbols that have not
+ been placed in specific sections (e.g. with the <code>section</code>
+ attribute, or the <code>-f{function,data}-sections</code> options) will
+ be placed in new, unique sections.
+ <br>
+ This functionality requires Binutils version 2.36 or later.
