Yeah, kernel is a good test case here, and it is not so hard to compile kernel as thumb2. Linux kernel can be a good evidence if we optimize its size when this work item is done. :) However, we'd like to probe any possible improvements on code size that we can do. This part is hard, and I have few ideas so far.
