pub unsafe fn _mm_maskz_max_sh(k: u8, a: __m128h, b: __m128h) -> __m128h🔬This is a nightly-only experimental API. (

Expand description
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 zeromask k (the element is zeroed out 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.
