[ACTIVITY] Weekly status

[Richard Sandiford]

== 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).
