We also wanted to use function names at the beginning of our work [1]. Then Jakub noticed that the names aren't necessarily unique: [2], [3], [4], etc. This led to the current approach of host/target address tables. > > Bernd > [1] http://gcc.gnu.org/ml/gcc/2013-08/msg00251.html [2] http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00250.html [3] http://gcc.gnu.org/ml/gcc/2013-09/msg00146.html [4] http://gcc.gnu.org/ml/gcc/2013-10/msg00184.html -- Ilya
