pub unsafe fn _mm_test_epi64_mask(a: __m128i, b: __m128i) -> u8
🔬 This is a nightly-only experimental API. (stdsimd)
This is supported on x86-64 and target feature avx512f,avx512vl only.
Expand description

Compute the bitwise AND of packed 64-bit integers in a and b, producing intermediate 64-bit values, and set the corresponding bit in result mask k if the intermediate value is non-zero.
