== This week ==

* Looked at the get_arm_condition_code ICE. Seems to be a popular bug: was reported as #589887 #823708 and #809761 in Lauchpad and as PR49030 in bugzilla. Sent a patch upstream.

* Submitted SMS register-dependency patch upstream.

* Reviewed Bernd's new shrink-wrap patch.

* Tried to clean up my microbenchmarks. Found that preloading the caches at the start of the benchmark fixed the variations I was seeing on a Beagleboard. (As Dave says, it seems that there's no allocation on write.) Added code to check the results of each loop. Packaged it up and pushed into bzr.

* An IBM colleague kindly tried my -fsched-pressure patch/hack on s390. Although it performed the best of the three runs (trunk, -fsched-pressure, patch+-fsched-pressure), there were some disappointing outliers. -fsched-pressure still introduces a 7% regression in one test (down from a 14% regression without the patch). Another test benefited from -fsched-pressure without my patch but regressed with it.

== Next week ==

* Look more at SMS.

* Look more at the sched-pressure thing (if I get time).
