* Looked at LP bug 736661. Sent a patch upstream. Some positive feedback, but it hasn't been approved or rejected yet.
* Looked at the old R_ARM_THM_CALL linker bug, after Matthias prepared a self-contained testcase (thanks). Attached a patch to the bug. Will submit upstream next week if testing goes OK.
* Looked at why the backport of lp823708-4.5 retriggered the same bootstrap failure that Chung-Lin's patch did. Haven't been able to reproduce yet.
* Looked at making the neon_vget_high/low patterns use ordinary subreg moves. Found that this triggered a fair few latent bugs in the rtl optimisers. Tried to fix those. This gave some nice improvements in some of the libav loops.
* Added h264 loops to the libav microbenchmarks.
* Blueprints.
* Upstream patch review.
