Function _mm_mask_sub_sh

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

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

Available on x86-64 only.

Subtract the lower half-precision (16-bit) floating-point elements in b from a, store the result in the lower element of dst, and copy the upper 7 packed elements from a to the upper elements of dst using writemask k (the element is copied from src when mask bit 0 is not set).
