The integer vector intrinsic listed below is designed for the Intel processors code-named "Prescott".
extern __m128i _mm_lddqu_si128(__m128i const *p);
Loads an unaligned 128-bit value. This differs from movdqu in that it can provide higher performance in some cases. However, it also may provide lower performance than movdqu if the memory value being read was just previously written.
r := *p;
