--- Comment #2 from Hongtao.liu ---
w/ -O0, it's defined as macro
#define _mm512_fpclass_ps_mask(x, c)\
((__mmask16) __builtin_ia32_fpclassps512_mask ((__v16sf) (__m512) (x),\
(int) (c),(__mmask8)-1))
and (__mmask16)-1 should be used
w/ -O2 it's ok
extern __inline __mmask16
__attribute__ ((__gnu_inline__, __always_inline__, __artificial__))
_mm512_fpclass_ps_mask (__m512 __A, const int __imm)
{
return (__mmask16) __builtin_ia32_fpclassps512_mask ((__v16sf) __A,
__imm,
(__mmask16) -1);
}
