--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. The two intrinsics (max and maxnm uses the same builtin):
```
__extension__ extern __inline float16_t
__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
vmaxh_f16 (float16_t __a, float16_t __b)
{
  return __builtin_aarch64_fmaxhf (__a, __b);
}

__extension__ extern __inline float16_t
__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
vmaxnmh_f16 (float16_t __a, float16_t __b)
{
  return __builtin_aarch64_fmaxhf (__a, __b);
}

__extension__ extern __inline float16_t
__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
vminh_f16 (float16_t __a, float16_t __b)
{
  return __builtin_aarch64_fminhf (__a, __b);
}

__extension__ extern __inline float16_t
__attribute__ ((__always_inline__, __gnu_inline__, __artificial__))
vminnmh_f16 (float16_t __a, float16_t __b)
{
  return __builtin_aarch64_fminhf (__a, __b);
}

```
