* 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.
