Integer Vector Intrinsics

The integer vector intrinsic listed here is designed for the Intel® Pentium® 4 processor with Streaming SIMD Extensions 3 (Intel® SSE3).

The prototype for this intrinsic is in the pmmintrin.h header file.

R represents the register into which the returns are placed.

__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.
