== This week ==

* Iterated with upstream on some of the vectorisation patches. I think only half a patch (the ARM implementation of array_mode_supported_p) is still pending review; everything else has been approved.

* Backported the vldN and vstN intrinsics to Linaro 4.5.

* Finished off the microbenchmarks for libav.

* One of the problems in the original libav output was that the vectoriser didn't realise that a group of N accesses really did form a group. It instead generated N separate interleave operations and took 1 vector from each.

Submitted a fix for that, which is now committed upstream. Updated the libav wiki page with the new, improved output.

(This actually allowed more libav loops to be vectorised, as well as improving the output from some of the existing ones. I haven't looked at the new ones. I expect this comes from interleaved stores.)

* Wrote an arm_neon.h version of Android's scanline_t32cb16_neon and compared it with the original.

* Started (and only started) seeing how the vectorisation stuff affects DENbench.

* Backported the dwarf2out OOM fix to Linaro 4.6.

== Next week ==

* Do something useful on DENbench.

* If all goes well, commit the vectorisation work upstream and backport it to Linaro 4.5 and 4.6.

...but it's only a three day week.
