+    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.
