This is inspired by the NIR sampler lowering code and I only realised
NIR seems to do its deref ordering different to GLSL at the last
minute, once I got that things got much easier.

it fixes a bunch of tests in
tests/spec/arb_gpu_shader5/execution/sampler_array_indexing/

v2: fix AoA tests when forced on.
I was right I didn't need all that code, fixing the AoA code
meant cleaning up a chunk of code I didn't like in the array
handling.

v3: start generalising the code a bit more for atomics.
v3.1: use UniformRemapTable

v4: handle uniforms differently using the param_index,
and go back to UniformStorage
fix issues identified by Timothy with deref handling.
v4.1: squash const fix and move handling 1D const out
of recursive function.

8 years agoglsl/ir: add param index to variable.
Dave Airlie [Mon, 8 Feb 2016 01:09:29 +0000 (11:09 +1000)]
glsl/ir: add param index to variable.

We have a requirement to store the index into the mesa parameterlist
for uniforms. Up until now we've overwritten var->data.location with
this info. However this then stops us accessing UniformStorage,
which is needed to do proper dereferencing.

Add a new variable to ir_variable to store this value in, and change
the two uses to use it correctly.
