* Benchmarking of simple package builds with various string routine versions; not finding enough difference in the noise to make any large conclusions<br>  * Looking at the string routine behaviour with perf to see where the time is going<br>
     - getting hit by the Linaro kernels on silverbell missing Perf enablement in the config<br>     - Useful amount of time does seem to be spent outside the main &#39;fast aligned&#39; chunks of code<br>     - pushing/popping registers does seem to be pretty expensive<br>
  * Started looking at libffi and hard float <br>     - Started writing a spec <a href="https://wiki.linaro.org/WorkingGroups/ToolChain/Specs/LibFFI-variadic">https://wiki.linaro.org/WorkingGroups/ToolChain/Specs/LibFFI-variadic</a><br>
     - It&#39;s going to need an API change to libffi, although the change shouldn&#39;t break any existing code on existing platforms where they work.<br>  * Helping with the image testing<br><br>Dave<br>
