#[target_feature(enable = "avx512dq", enable = "avx512vl")]
pub fn _mm256_mask_reduce_ps(src: __m256, k: __mmask8, a: __m256, IMM8: i32) -> __m256Extract the reduced argument of packed single-precision (32-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:
