After gimplification:
  D.1853 = *t;
  if (D.1853 == __complex__ (0.0, 0.0))
    {
      D.1854 = __complex__ (0.0, 0.0);
      iftmp.0 = &D.1854;
    }
  else
    {
      D.1855 = *t;
      D.1856 = -D.1855;
      iftmp.0 = &D.1856;
    }
  D.1857 = REALPART_EXPR <*iftmp.0>;
  *b = D.1857;


Before:
  *b = REALPART_EXPR <*t == __complex__ (0.0, 0.0) ? __complex__ (0.0, 0.0) :
-*t>;


I have not figured out why we need to take the address of the temp variable
yet.
