* Linaro GCC 4.4/4.5

Merged the latest CS patches and Linaro merge requests into Linaro GCC (4.4 and 4.5). Ran regression tests. Yao's patch failed so I backed it out, and made the release tarballs. Uploaded the releases to Michael Hope for release.

lp:686381: luatex fails to build with gcc-4.5 Fired off a test build to reproduce the problem. Will come back to this next week.

* GCC 4.6/4.7

Posted my various queued patches up to gcc-patches@gcc.gnu.org for review.

Looked at the state of the GCC 4.6 upstream build. There are currently two problems:

1. libquadmath must be disabled in a cross-build for the bootstrap phases. 2. libstdc++ doesn't build. There is a patch for it on the mail list, but it's not applied yet.

Once gcc 4.6 builds cleanly, I shall update the Launchpad 4.6 branch, and declare that the baseline for our development. We'll then have somewhere to commit and track patches awaiting GCC stage 1 development.

Caught up with email following my holiday.

Yet again, my IGEPv2 board suffered a corrupt file system. I've now upgraded the kernel and configured it to use an NFS root. The board is now somewhat less mobile, but should work more reliably.

Continued organizing the a brain-storming session for GCC optimization improvements.

Organised flights and hotel for both the Linaro Sprint and CodeSourcery annual meeting in January.
