I did on multiple occasions (last was
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg01521.html) , never got an okay.
Meanwhile Jakub implemented a different mean which doesn't call the get_attr_
functions dynamically more often (which my approach potentially does), but
which as result isn't nearly as effective in reducing size and compile and
generation time.
Some of the hunks of my patch still are useful cleanups/speedups, lemme
submit them.
