*  Roadmap / Connect
  * Completed End of quarter 2011Q4 reports
  * Set the sessions for Connect
  * Plan for 2012Q1 https://wiki.linaro.org/MichaelHope/Sandbox/Q1.12Plans

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

* OpenEmbedded
  * Changed Qt build to respect the optimization flags
  * Wrote a script around QEMU to measure the memory footprint using named pipes to communicate with the serial console of the guest
 
* GDB
  * Committed follow-on patch to fix cosmetic issues resulting from the remote "info proc" patch set.

* GCC
  * Created 4.6 backport branch including subreg forward- propagation branch,
    the modes-tieable patch, and the combine.c regression fix, and evaluated
    for correctness and performance.
  * Investigated Ramana's vld1 patches, and a problem with excessive vmov's
    in the PR 51819 test case pointed out by Ramana. 

* QEMU
  * Wrote patches for the A15 Fast Models boot-wrapper that allow you
    to pass the kernel/initrd/kernel command line via a parameter to
    the model rather than having to hard code them into an ELF file
    along with the boot-wrapper.
  * target-arm/arm-devs queues pushed upstream [Calxeda Highbank model is now in upstream QEMU]

 * KVM
    * Sorted out a Debian fs to use for KVM guest : this is needed because
      the kernel module doesn't do Thumb or VFP yet.
    * Wrote wiki pages on how to reproduce the KVM prototype  https://wiki.linaro.org/PeterMaydell/KVM/HowTo
    * Upstream patch review, many complicated things landing
    * Reviewed KVM ARM patches from Christoffer

 * Benchmarking
   * 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.

Best regards,
Mounir
