+ <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>,
+ <code>_Float16</code> type is storage only, all operations will be
+ emulated by software emulation and the <code>float</code> instructions.
+ </li>
