<li>GCC can now utilize the SVML library for vectorizing calls to
a set of C99 functions if <code>-mveclibabi=svml</code> is specified
and you link to an SVML ABI compatible library.</li>
+ <li>The following changes have been made to conform to x86-64 ABI:
+ <ul>
+ <li>Passing/returning structures with flexible array member.</li>
+ <li>Passing/returning structures with complex float member.</li>
+ <li>Passing/returning unions with long double member.</li>
+ </ul></li>
<li>A new <code>target</code> attribute was added to allow programmers to change the target options like <code>-msse2</code> or <code>-march=k8</code> for an individual function. You can also change the target options via the <code>GCC target</code> pragma for functions defined after the pragma.</li>
<li>GCC can now be configured with
options <code>--with-arch-32</code>, <code>--with-arch-64</code>,
