Temporarily took over Tech Lead of the Toolchain Working Group while Michael Hope recovers from the Christchurch earthquake. (He's fine, but unable to work.) This didn't actually require any action, in the end. Michael returned to work towards the end of the week.

Forward ported, benchmarked, and posted one of Mark Shinwell's NEON patches upstream.

Further benchmarking was not possible as the Panda board I was using is located in Christchurch, NZ.

Merged and tested the FSF GCC 4.5 branch into Linaro GCC. There were a couple of test regressions in the fortran testsuite, so I've filed bug lp:723086. The other test results were either the same or better.

Benchmarked the ARM A8 function/jump alignment patch to see what effect it has in GCC 4.6. Found no measurable improvement in EEMBC. I suggest dropping this patch.

Brought the patch tracker up-to-date, and entered tracking tickets for all outstanding patches.

Merged FSF trunk to Linaro GCC 4.6.

Committed Jie's Thumb2 testcase fix to FSF GCC trunk. Thanks to Ramana for using his new found authority to approve it.

Investigated the suitability of several of the patches for forward-porting. Corresponded with Benrd and Julian.
