pub unsafe fn _ktest_mask64_u8(a: u64, b: u64, and_not: *mut u8) -> u8🔬This is a nightly-only experimental API. (
stdarch_x86_avx512)Available on x86-64 only.
Expand description
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.
