Function _mm_maskz_reduce_pd

pub unsafe fn _mm_maskz_reduce_pd(
    k: __mmask8,
    a: __m128d,
    const IMM8: i32,
) -> __m128d

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512dq,avx512vl and x86 only.

Extract the reduced argument of packed double-precision (64-bit) floating-point elements in a by the number of bits specified by imm8, and store the results in dst using zeromask k (elements are zeroed out if the corresponding mask bit is not set). Rounding is done according to the imm8 parameter, which can be one of:

- _MM_FROUND_TO_NEAREST_INT // round to nearest
- _MM_FROUND_TO_NEG_INF     // round down
- _MM_FROUND_TO_POS_INF     // round up
- _MM_FROUND_TO_ZERO        // truncate
- _MM_FROUND_CUR_DIRECTION  // use MXCSR.RC; see _MM_SET_ROUNDING_MODE
