* Backported fix for returning std::pair. Unfortunately
this showed up a regression on 4.5. I couldn't reproduce it cross,
and the testcase itself looks innocuous, so I'm wondering whether
the patch might trigger a miscompilation of cc1plus.
* Committed SMS regis
Completed the 4.5 and 4.6 FSF to Linaro merges.
Spun the Linaro GCC release tarballs, uploaded them to the test farm,
and set off the test builds.
Continued looking at the constant reuse optimization. This time I've
build GCC itself with the new pass to see how many optimization
opportunitie
==Progress===
* Some patch review.
* Spent time looking at LP 836588.
* Tried some different approaches for the vcvt.f64.s32 case and it
looks like the simple solution is the best one unfortunately :(
* 2 days off at internal training course.
=== Plans ===
* continue looking into LP 836588
