Function core::arch::x86::_mm_mask_fpclass_ph_mask

pub unsafe fn _mm_mask_fpclass_ph_mask(
    k1: __mmask8,
    a: __m128h,
    const IMM8: i32,
) -> __mmask8

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16 #127213)

Available on (x86 or x86-64) and target feature avx512fp16,avx512vl,avx512f,sse and x86 only.

Test packed half-precision (16-bit) floating-point elements in a for special categories specified by imm8, and store the results in mask vector k using zeromask k (elements are zeroed out when the corresponding mask bit is not set). imm can be a combination of:

0x01 // QNaN
0x02 // Positive Zero
0x04 // Negative Zero
0x08 // Positive Infinity
0x10 // Negative Infinity
0x20 // Denormal
0x40 // Negative
0x80 // SNaN
