Why do Gallium drivers use ir_to_mesa? That seems like a misfeature.
Because Gallium drivers still use paramlist for uniforms. I'm sure we
could duplicate the code (most of glsl->tgsi seems to be copied from
ir_to_mesa at some point), it just doesn't seem to have been done for
whatever reason.
i965 still uses paramlist for a bunch of uniforms too.
Only for asm programs if I recall correctly.
You do need to
duplicate some logic, but you get to drop piles of it too.
Not really, not unless every Gallium driver is updated to handled packed
uniforms :)
It might
be worth looking at brw_link.cpp...
I'm working on a series to support packed uniforms, which reduces a
bunch of CPU overhead. It still uses paramlist but it's a stepping stone.
