    pub unsafe fn _mm256_reduce_ps(a: __m256, const IMM8: i32) -> __m256

🔬This is a nightly-only experimental API. (`stdarch_x86_avx512` #111137)
Available on (x86 or x86-64) and target feature `avx512dq,avx512vl` and x86-64 only.
Expand description

Extract 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. 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
