Just to add to this, we need to work with the Ubuntu guys to ensure that all problems caused by this compiler change are tracked. I've seen a few bugs going past where the Ubuntu maintainers quickly "fix" the affected package by building with -marm. This is OK for getting the package building in the short term, but we need to be careful to ensure these problems aren't forgotten about. Secondly, the people maintaining the affected upstream projects may not be builing for Thumb-2 regularly-- this means that packages may break again due to upstream maintenance. In rare cases, maintenance changes which cause incorrect execution in Thumb-2 might not cause build failures. We need to be vigilant about this, and accompany changes pushed upstream with comments advising how to avoid this. I expect the most practical approach is to write up advice on the wiki or somewhere, and refer developers to it, especially linaro and ubuntu-arm guys. I can have a go at drafting that, but it may not happen until January...
