The idea would indeed have been that drivers would just do that on their
own if the

The fact r300 has ARL is well known. However, r600 has it too. The
r600 equivalent of ARL is "MOVA", which allows translating TGSI
indirect addressing into bytecode directly. So there is a rather
significant user base of gallium which uses hardware with ARL.
I am not opposed to the idea of nuking

Hi,
for Gallium Nine we use ARR and UARL.
Do all cards supporting integers support indexing with an integer register ?
If yes we could remove our UARL usage.
As for ARR, if all cards are ok with normal registers, we could use a
normal one
too, as long as we can get the same rounding behaviour
Hi,
the address reg in tgsi is quite a nuisance. glsl-to-tgsi code assumes
that indirections can only be done through the address reg and has quite
some extra code to deal with this. Even though hardware and apis which
worked like that are definitely old by now.
Thus, I'm proposing the address reg
