wow!
So why is gcc 4.0 producing worse code when using intel style
intrinsics and why isn't the union version using builtins as fast as
using the vector version?
I can answer why unions are slower: that's

Hi,
I noticed something strange when I use GCC's builtins for MMX:
I defined some unions:
typedef int v4hi __attribute__ ((__mode__(__V4HI__)));
typedef int v2si __attribute__ ((__mode__(__V2SI__)));
typedef int di __attribute__ ((__mode__(__DI__)));
typedef union
{
v4hi v;
short s[4];
int i[
