Continued work on my constant reuse optimizations. Not too much this week though. I've now fixed some issues with the ARM size-costs code that was causing it to wildly over-estimate the cost of a MOVT instruction. I'll have to post this upstream sometime soon.

Took another look at the shift-amount bug. Discussed the issue with Paul Brook. I've now fixed the original bug, and fixed the new bug introduced by Paul's original fix, and committed that upstream. I still need to backport it to Linaro GCC though, and the latent bug that Richard S spotted is still being analysed.

Did a merge from FSF 4.5 & 4.6 to Linaro, and pushed them the Launchpad branches for testing.

Begun work benchmarking different setups for the generic tuning patches. I had a lot of trouble trying to set up SPEC2000 though. Hopefully these issues are now resolved, with some help from Michael, and I have established some baseline figures on both A8 and A9 to work from.

No progress on native tuning. I'm still waiting for upstream review.

In other news: Mentor's contract with Linaro has now been extended for another 6 months. :)
