I'm curious, does ICC support vector arithmetic like this? 
The primary icc/icl use of SSE/SSE2 masking operations, of course, is in 
the auto-vectorization of fabs[f] and conditional operations:

     sum = 0.f;
     i__2 = *n;
     for (i__ = 1; i__ <= i__2; ++i__)
         if (a[i__] > 0.f)
             sum += a[i__];
.... (Windows/intel asm syntax)
      pxor      xmm2, xmm2
      cmpltps   xmm2, xmm3
      andps     xmm3, xmm2
      addps     xmm0, xmm3
...
