* Worked on quad-word/big-endian fixes patch. Sent off a version on Tuesday which worked OK, but which made some awkward changes to the middle-end. Tried to re-think those parts, but without much luck: came to the conclusion that spending more time trying to fix element-ordering-dependent operations on quad-word vectors in big-endian mode was probably not worth the effort (since we plan to be changing things in that area anyway). Wrote a much-simplified patch which simply disables those patterns, and ported it to mainline.

* Then, spent some time trying to set up big-endian testing with a mainline build, since the lack of such an option is partly why we got into this mess to start with. My current plan (as well as testing the above patch) is to create an upstreamable patch to easily enable big-endian (Linux) multilibs, in the hope that it'll generally make big-endian testing easier. (Of course people will still need test harness configurations which will allow running big & little-endian code, which most won't have.)

* Also, ping lp675347 (volatile bitfields vs. QT atomics), and do some some extra checks suggested by DJ Delorie, which seemed to work out fine. Backported patch for lp629671 to Linaro 4.4 branch, and ran tests (also fine).

* Continued discussion of internal representations for fancy vector loads/stores in GIMPLE/RTL on linaro-toolchain.
