Bernd, I read you're interested in code-size optimizations. I'd like to point you to this patch: http://gcc.gnu.org/ml/gcc-patches/2005-05/msg00554.html
which was never finished nor committed (I don't know if RTH has a newer version though). This is would be of great help for code size issues in AVR, but I don't know if and how much it'd help for Blackfin. -- Giovanni Bajo
