== This week ==

* Looked at why the fix for #721531 wasn't working on the Linaro branches. Wrote follow-up patches for both. Fix now committed to 4.5 and 4.6.

* Looked at #736007. Submitted and committed patch upstream.

* Looked at some "odd" ivopts behaviour. It turned out that this was working mostly as expected. I'm still wondering about a couple of tweaks.

* Looked briefly at a miscompilation of vector code that turned out to occur during predictive commoning. I haven't yet checked whether the bug is there or not. For the time being, I'm using -fno-predictive-commoning so that I can get on with other stuff.

* Looked at why the auto-inc-dec stuff wasn't as effective with current mainline. It turns out that the new misaligned load/store patterns are using overly weak predicates, so it appears to the RTL optimisers as though we support reg+offset addresses.

* Reviewed the shrink-wrap patch.

* More auto inc/dec.

== Next week ==

* Backport the fix for #736007.

* More loop stuff.
