+      <dd>The new vectorization feature that exploits intra-iteration parallelism
+ 	 (to be submitted to GCC 4.3) was presented at the GCC summit last week ("Loop-aware SLP").
+ 	 Also at the summit, we held a BOF on vectorization and other loop optimizations. The summary
+ 	 of the BOF can be found here: <a href="http://gcc.gnu.org/wiki/LoopOptimizationsBOF">
+ 	 http://gcc.gnu.org/wiki/LoopOptimizationsBOF</a>. Following the BOF the vectorizer's todo list 
+ 	 was also updated (<a href="http://gcc.gnu.org/wiki/VectorizationTasks">
+ 	 http://gcc.gnu.org/wiki/VectorizationTasks</a>).
+      </dd>
+      <dd>Mainline updates:
+      <ol>
+         <li>SPU specific costs for the cost model committed to mainline (2007-07-12).
+ 	    Tuning for other platforms (PPC, X86) ongoing.  </li>
+         <li>Initial cost model implementation committed to mainline (2007-06-08).  </li>
+         <li>Vectorization of fp/integer conversions of different sizes (e.g. float/short)
+             committed to mainline (2007-05-17).</li>
+         <li>Data-refs analysis was rewritten and improved (2007-05-13).  </li>
+      </ol>
+      </dd>
+      <dd>Autovect-branch updates:
+      <ol>
+         <li>Outer-loop vectorization was enhanced to support aligned and unaligned 
+ 	    memory references in the inner-loop, using the optimized realignment
+ 	    scheme when possible.  </li>
+         <li>Vectorization that exploits intra-iteration parallelism (ala SLP)
+ 	    was added to the vectorizer (that so far exploited only inter-iteration
+ 	    parallelism).  </li>
+         <li>The vectorizer cost model was extended to support the above two new vectorization
+ 	    features (outer-loop and "SLP").  </li>
+      </ol>
