Of course tSSEVector should be declared in System unit.
Then any one can use SSE intentionally
Why can't you now? It's not like multiplication has any other meaning
for arrays. And declaring "magic compiler types" in the system unit is
something that should be avoided as much as possible (it makes both
the compiler and rtl harder to adapt and understand).
Of course, but SIMD is thing, which has more and more impact to
performance. And compiler should respect it (and do this, as Florian
said). But till now nobody know, where compiler use SSE instruction.
Of course one knows. For array operations as shown SSE/SSE2 is used if
enabled.

Ok. I only want to discover how to use it.
if I write
type
tSSEVector = array[0..1] of double
var
d1 : tSSeVector;
d2 : array[0..1]of tSSEVector;
begin
d1:=d2[0]*d2[1];
end;
will be work too?
Yes.
Thanks. Now I understand.
Or something like this:
function f ;
var
d1,d2,d3 : array[0..4] of integer;
begin
d1:=d2*d3;
end;
No. Not yet implemented iirc.
But will be in the same manner?
