Source

    pub fn _mm_maskz_sub_epi64(k: __mmask8, a: __m128i, b: __m128i) -> __m128i

🔬This is a nightly-only experimental API. (`stdarch_x86_avx512` #111137)
Available on (x86 or x86-64) and target feature `avx512f,avx512vl` and x86 only.
Expand description

Subtract packed 64-bit integers in b from packed 64-bit integers in a, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
