I'm no expert in this matters but I think what you did is a great idea, especially considering the limited amount of people which have the knowledge to be able to work on mesa. > The code is at: > > git://anongit.freedesktop.org/~nh/mesa r300-compiler > http://cgit.freedesktop.org/~nh/mesa/log/?h=r300-compiler > > The current state is: > > .
