Completed the merge of FSF GCC 4.5 & 4.6 to Linaro GCC. There were a few extra test failure in the i686 testing for both toolchains, but x86_64 and arm were clean, so it seems likely to be an environmental issue (in particular, some of the failures were linker crashes).

Posted an update to my widening multiplies patch 3. This one hopefully addressed the issues found by Richard Guenther. Also tested an posted updates to my other patches that had their context changed.

Richard picked more holes in my patch, and also reviewed patches 4, 5 and 6. 4 & 5 only have minor issues so far, and 6 has actually been approved! :)

Rewrote patch 3 yet again following review. Richard has now modified the VRP pass to make the widening pass's job simpler, so I don't need it to do as much. Also rebaslined the whole patch set; Bernd's recent patch has introduced some conflicts.

Found (some of?) the bugs that broke my thumb2 constants patch. Pushed the updated patch to Launchpad for testing.

Updated a lot of the patch tracker data.

Half day Thursday.
