Isn't it just _mm_storel_epi64 ?

I have a bit of code that needs to store the low 8 bytes of an SSE

right instruction for this, but it doesn't appear to have a built-
in intrinsic. Apple's documentation states:
"SSE provides a rich set of scalar loads and stores. MOVQ and MOVD
can be used to move 8- and 4-byte integers to and from the low
element on the XMM vector."
but gives no hint how to code this with intrinsics. In other words,
my function is:
// ____ store low 8 bytes of v to unaligned address p
void Store64(char* p, vSInt8 v);
How do I code this?
