--- Comment #7 from Dave Airlie <airlied at freedesktop.org> ---
I've worked around this in the TGSI->GLSL convertor so it allocates separate
temp arrays for the TGSI input ranges, I hadn't considered the compiler would
fall over on that at all, but it makes sense.

I don't think I can generate the const initialisers however, since the TGSI is
just a bunch of MOVs, it would take a lot of effort to try and make sure it was
safe to bump them to const inits. Might look into it another time.
