-That makes me wonder whether we have any dead functions that can be nuked to reduce size. On a similar note [[http://​gcc.gnu.org/​gcc-4.5/​changes.html|gcc 4.5.0]] introduced whole program optimizations,​ which might be worth looking into.+That makes me wonder whether we have any dead functions that can be nuked to reduce size. Also on a similar note [[http://​gcc.gnu.org/​gcc-4.5/​changes.html|gcc 4.5.0]] introduced whole program optimizations,​ which might be worth looking into.
