== Linaro GCC ==
* Finished testing patch for lp675347 (QT inline-asm atomics), and send upstream for comments (no response yet). Suggested reverting a patch (which enabled -fstrict-volatile-bitfields by default on ARM) locally for Ubuntu in the bug log.
* Continued working on NEON quad-word vectors/big-endian patch. This turned out to be slightly fiddlier than I expected: I think I now have semantics which make sense, though my patch requires (a) slight middle-end changes, and (b) workarounds for unexpected combiner behaviour re: subregs & sign/zero-extend ops. I will send a new version of the patch to linaro-toolchain fairly soon for comments.
