title: Is there a SSE2 equivalent for _mm_insert_epi32?
body: <p>I'm porting some code, which makes heavy use of SSE4-intrinsics. It has a non-SSE implementation, but I'd like CPUs with only SSE2 to still be able to use the faster functions.</p>
  
  <p>Could someone suggest an efficient replacement for <code>_mm_insert_epi32</code> -- I think, I got everything else covered already... In fact, the second and the third arguments of the function are zeros in my case:</p>
  
  
  
  <pre><code>foo = _mm_insert_epi32(vec, 0, 0);
  </code></pre>
