Function core::arch::x86::_mm_mask_max_round_ss

pub unsafe fn _mm_mask_max_round_ss(
    src: __m128, 
    k: __mmask8, 
    a: __m128, 
    b: __m128, 
    const SAE: i32
) -> __m128

🔬 This is a nightly-only experimental API. (stdsimd #48556)

Available on x86 and target feature avx512f only.

Compare the lower single-precision (32-bit) floating-point elements in a and b, store the maximum value in the lower element of dst using writemask k (the element is copied from src when mask bit 0 is not set), and copy the upper 3 packed elements from a to the upper elements of dst.
Exceptions can be suppressed by passing _MM_FROUND_NO_EXC in the sae parameter.
