+   <li>Support has been added for the Arm EABI on NetBSD through the
+   <code>arm*-*-netbsdelf-*eabi*</code> triplet.

+   <li>The handling of 64-bit integer operations has been significantly reworked

+   deprecated and will be removed in a future release.</li>
+   <li>
+        Support has been added for the following processors
+        (GCC identifiers in parentheses):

+ 	 <li>Arm Cortex-M35P (<code>cortex-m35p</code>).</li>
+        </ul>
+        The GCC identifiers can be used
+        as arguments to the <code>-mcpu</code> or <code>-mtune</code> options,
+        for example: <code>-mcpu=cortex-a77</code> or
+        <code>-mtune=cortex-m35p</code>.

+   <a href="https://developer.arm.com/docs/101028/0009/data-processing-intrinsics">
+   data-processing intrinsics</a> to include 32-bit SIMD, saturating arithmetic,

+   optimization.
