pub unsafe fn _mm_maskz_max_sd(k: u8, a: __m128d, b: __m128d) -> __m128d🔬This is a nightly-only experimental API. (
stdarch_x86_avx512)Available on x86 only.
Expand description
Compare the lower double-precision (64-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 element from a to the upper element of dst.
