Function _mm_mask_max_sh

pub unsafe fn _mm_mask_max_sh(
    src: __m128h,
    k: u8,
    a: __m128h,
    b: __m128h,
) -> __m128h

🔬This is a nightly-only experimental API. (stdarch_x86_avx512_f16)

Available on x86 only.

Compare the lower half-precision (16-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 7 packed elements from a to the upper elements of dst. Does not follow the IEEE Standard for Floating-Point Arithmetic (IEEE 754) maximum value when inputs are NaN or signed-zero values.
