Function serde::lib::core::arch::x86_64::_mm256_mask_reduce_pd

pub unsafe fn _mm256_mask_reduce_pd<const IMM8: i32>(
    src: __m256d,
    k: u8,
    a: __m256d,
) -> __m256d

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

Available on x86-64 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 writemask k (elements are copied from src to dst 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
