Synopsis
_mm_mask_loadu_epi64(__m128i src, __mmask8 k, void const* mem_addr);
Description
Load packed 64-bit integers from memory into "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
"mem_addr" does not need to be aligned on any particular boundary.
Operation
FOR j := 0 to 1
i := j*64
IF k[j]
dst[i+63:i] := MEM[mem_addr+i+63:mem_addr+i]
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:128] := 0
