<ul>
+ <li>GCC now supports AMD CPUs based on the Zen6 core via
+ <code>-march=znver6</code>. This switch enables the
+ AVX512_BMM, AVX_NE_CONVERT, AVX_IFMA, AVX_VNNI_INT8 and
+ AVX512_FP16 ISA extensions on top of ISA extensions enabled
+ for Zen5.
+ </li>
+ <li>Auto-vectorization will now try to use a masked vector epilog when
+ AVX512 support is enabled and tuning for <code>znver4</code>,
+ <code>znver5</code> or <code>znver6</code>, saving code size
+ and improving performance.
+ </li>
<li>GCC now supports the Intel CPU named Wildcat Lake through
<code>-march=wildcatlake</code>.
Wildcat Lake is based on Panther Lake.
