The LD message ignores the sampler unit index and SAMPLER_STATE pointer,
instead relying on hard-wired default state. Thus, there's no need to
worry about running out of sampler units or providing SAMPLER_STATE;
this small patch should be all that's required.
This looks much nicer than the previous patchset :)
I do wonder about the args to ld, though. In 4x2 mode, it's "u v r
lod". get_pull_constant_offset is filling .x with the dword offset, and
.yzw are undefined. Is that what ld wants, or does it make use of v and
r (.y and .z)?
I've spammed .x into .xyzw and everything worked, which suggests that it
really does ignore .yzw. So I think we should be fine.
