+ <ul>
+ <li>Minor improvements to code generated for integer arithmetic and code
+ that involves the T bit.</li>
+
+ <li>Added support for the SH2A <code>clips</code> and <code>clipu</code>
+ instructions. The compiler will now try to utilize them for min/max
+ expressions such as <code>max (-128, min (127, x))</code>.</li>
+
+ <li>Added support for the <code>cmp/str</code> instruction through built-in
+ functions such as <code>__builtin_strlen</code>. When not optimizing for
+ size, the compiler will now expand calls to e.g. <code>strlen</code> as an
+ inlined sequences which utilize the <code>cmp/str</code> instruction.</li>
+
+ <li>Improved code generated around volatile memory loads and stores.</li>
+
+ <li>The option <code>-mcbranchdi</code> has been deprecated. Specifying it
+ will result in a warning and will not influence code generation.</li>
+
+ <li>The option <code>-mcmpeqdi</code> has been deprecated. Specifying it
+ will result in a warning and will not influence code generation.</li>
