Synopsis
_mm_maskload_epi64(__int64 const* mem_addr, __m128i mask);
Description
Load packed 64-bit integers from memory into "dst" using "mask" (elements are zeroed out when the highest bit is not set in the corresponding element).
Operation
FOR j := 0 to 1
i := j*64
IF mask[i+63]
dst[i+63:i] := MEM[mem_addr+i+63:mem_addr+i]
ELSE
dst[i+63:i] := 0
FI
ENDFOR
dst[MAX:128] := 0
