+  <li>New ISA extension support for Intel AVX512-FP16 was added to GCC.
+      AVX512FP16 intrinsics are available via the <code>-mavx512fp16</code>
+      compiler switch.
+  </li>
+  <li>For both C and C++, The <code>_Float16</code> type is supported on
+      x86 systems with SSE2 enabled. Without <code>{-mavx512fp16}</code>,
+      all operations will be emulated by software emulation and the
+      <code>float</code> instructions.
