# Function core::arch::x86_64::_mm_cmple_epu64_mask
[−][src]

    pub unsafe fn _mm_cmple_epu64_mask(a: __m128i, b: __m128i) -> __mmask8

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512f,avx512vl` only.

Compare packed unsigned 64-bit integers in a and b for less-than-or-equal, and store the results in mask vector k.
