Function core::arch::x86::_ktest_mask64_u8

pub unsafe fn _ktest_mask64_u8(
    a: __mmask64,
    b: __mmask64,
    and_not: *mut u8,
) -> u8

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avx512bw and x86 only.

Compute the bitwise AND of 64-bit masks a and b, and if the result is all zeros, store 1 in dst, otherwise store 0 in dst. Compute the bitwise NOT of a and then AND with b, if the result is all zeros, store 1 in and_not, otherwise store 0 in and_not.
