Ok, I got the trunk to build now. Luckily indeed the emitted assembler code has improved (a lot). Yet the produced code is still a bit larger than what it would be if written by hand. Since I try to optimize for size, my question how it would be smart to tackle this within LLVM remains.

Thanks for any feedback.
