+    extensions have been split from <code>loongson3a</code>:
+    <ul>
+       <li><code>loongson-mmi</code> contains
+       the Loongson MMI (MultiMedia extensions Instructions).</li>
+       <li><code>loongson-ext</code> contains
+       the Loongson EXT (EXTensions instructions).</li>
+    </ul>
+  </li>
+  <li>
+    The Loongson EXT2 (EXTensions R2 instructions) are now supported.
+    <ul>
+       <li><code>loongson-ext2</code> contains the Loongson EXT2 instructions.</li>

+    Command-line options<code>-m[no-]loongson-mmi</code>,
+    <code>-m[no-]loongson-ext</code>, and <code>-m[no-]loongson-ext2</code>

+    Support has been added for the following processors
+    (GCC identifiers in parentheses):
+    <ul>
+	<li>Loongson 3A1000 (<code>gs464</code>)
