Do you have any SSE examples that show a speed gain? My own experiments were
not very encouraging.
This:
operator +(const v1,v2: TVector4): TVector4; assembler; inline;
Asm
movups xmm0, [v1]
addps xmm0, [v2]
movups [Result], xmm0
end;
is slower than this:
operator+(const a, b: TVector4): TVector4;
begin
with Result do begin
x:=a.x+b.x;
y:=a.y+b.y;
z:=a.z+b.z;
w:=a.w+b.w;
end;
end;
