<br><br>*  Roadmap / Connect <br>  * Completed End of quarter 2011Q4 reports<br>  * Set the sessions for Connect<br>  * Plan for 2012Q1 <a href="https://wiki.linaro.org/MichaelHope/Sandbox/Q1.12Plans" target="_blank">https://wiki.linaro.org/MichaelHope/Sandbox/Q1.12Plans</a><br>

<br>* 64-bit <br>  * Submitted work on 64-bit shift in core registers patches upstream, awaiting review.<br>  <br>*  libunwind <br>   * Reviewed a patch from T. R. of Nokia who provided a bugfix in case unwind instructions are popping VFP registers<br>

<br>* OpenEmbedded<br>  * Changed Qt build to respect the optimization flags<br> 
 * Wrote a script around QEMU to measure the memory footprint using 
named pipes to communicate with the serial console of the guest<br> <br>
* GDB <br>  * Committed follow-on patch to fix cosmetic issues resulting from the remote &quot;info proc&quot; patch set.<br><br>* GCC<br>  * Created 4.6 backport branch including subreg forward- propagation branch, <br>
    the modes-tieable patch, and the combine.c regression fix, and evaluated <br>
    for correctness and performance. <br>  * Investigated Ramana&#39;s vld1 patches, and a problem with excessive vmov&#39;s <br>    in the PR 51819 test case pointed out by Ramana.  <br><br>* QEMU <br>  * Wrote patches for the A15 Fast Models boot-wrapper that allow you<br>

    to pass the kernel/initrd/kernel command line via a parameter to<br>    the model rather than having to hard code them into an ELF file<br>    along with the boot-wrapper. <br>  * target-arm/arm-devs queues pushed upstream [Calxeda Highbank model is now in upstream QEMU]<br>

<br> * KVM <br>    * Sorted out a Debian fs to use for KVM guest : this is needed because <br>      the kernel module doesn&#39;t do Thumb or VFP yet.<br>    * Wrote wiki pages on how to reproduce the KVM prototype  <a href="https://wiki.linaro.org/PeterMaydell/KVM/HowTo" target="_blank">https://wiki.linaro.org/PeterMaydell/KVM/HowTo</a><br>

    * Upstream patch review, many complicated things landing<br>    * Reviewed KVM ARM patches from Christoffer<br><br> * Benchmarking<br>  
 * Continued benchmarking gcc-4.7 against gcc-linaro-4.6-2012.01 and 
gcc-4.6 with  -o2 and -o3 variants, both with neon enabled. <br>
