+<ul>
+  <li>
+    The internal implementation of Power's target-specific built-in functions
+    has been rewritten to be easier and less error-prone to maintain.  Every
+    attempt has been made to ensure that the new behavior matches the old
+    behavior, but inevitably some bugs can be expected.  Please report any
+    problems using <a href="https://gcc.gnu.org/bugzilla">GCC Bugzilla</a>.
+  </li>
+  <li>
+    The built-in functions <code>__builtin_get_texasr</code>,
+    <code>__builtin_get_texasru</code>, <code>__builtin_get_tfhar</code>,
+    <code>__builtin_get_tfiar</code>, <code>__builtin_set_texasr</code>,
+    <code>__builtin_set_texasru</code>, <code>__builtin_set_tfhar</code>, and
+    <code>__builtin_set_tfiar</code> now behave as documented in all
+    supported configurations.  On prior releases, the arguments and return
+    values of these functions were treated as <code>unsigned long long</code>
+    instead of as <code>unsigned long</code>, when the options <code>-m32
+    -mpowerpc64</code> were in effect.
+  </li>
