pub unsafe fn _mm_mask_expandloadu_epi64(src: __m128i, k: __mmask8, mem_addr: *const i64) -> __m128iLoad contiguous active 64-bit integers from unaligned memory at mem_addr (those with their respective bit set in mask k), and store the results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
