<li>Code generation for the 32-bit integer shifts with constant
offset has been improved. The code size may slightly increase even
when optimizing for code size with <code>-Os</code>.</li>
+ <li>Support has been added for a <em>compact vector table</em> as supported
+ by some AVR devices. It can be activated by the new command-line option
+ <a href="https://gcc.gnu.org/onlinedocs/gcc/AVR-Options.html#index-mcvt";
+ ><code>-mcvt</code></a>.
+ It links <code>crt<i>mcu</i>-cvt.o</code> as startup code which
+ is supported since AVR-LibC v2.3.</li>
<li>New AVR specific optimization passes have been added.
They run after register allocation and can be controlled by the new
command-line options
