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