The benchmark fails to start, the translation of gl_Identity is incorrect,
UMAD TEMP[0], SV[0].xxxx, TEMP[0].xxxx, TEMP[1]
is translated to:
temp0[0] = vec4(uintBitsToFloat((gl_InstanceID * floatBitsToUint(temp0[0].xxxx) + floatBitsToUint(temp0[1]))));
Which results in the following error:
shader failed to compile
0:23(34): error: could not implicitly convert operands to arithmetic operator
0:23(34): error: operands to arithmetic operators must be numeric
0:23(17): error: no matching function for call to `uintBitsToFloat(error)'; candidates are:
It seems we can use the same workaround as gl_VertexID, I didn't
observe any regression running various gl_InstanceId tests from
piglit:
temp0[0] = vec4(uintBitsToFloat((floatBitsToUint(vec4(intBitsToFloat(gl_InstanceID))) * floatBitsToUint(temp0[0].xxxx) + floatBitsToUint(temp0[1]))));

Some piglit tests read/write outside of fix-sized arrays. Return an
error in this case. Note: further investigation needed to avoid
such access in the first place.

We weren't converting integer sampler results correctly,
so bad things ensued, this uses the info in the sampler
view to recreate the proper return values and do the
correct casting.
We are seeing shaders with 0 and 2 inputs, but no 1, so we need
to handle gaps properly.
This fixes some regressions in drawpixels after some mesa changes
on the guest.
TXQ may query levels and size.
Fixes all piglit texturesize tests and others.
[airlied: use EMIT_BUF_WITH_RET].

Create a bunch of temp arrays based on the input TGSI
ranges. Otherwise the temps code triggers a lack of
some passes in the mesa GLSL compiler.
A large shader from shadertoy triggered 1m30s compile in mesa
due to the large temp array.

This updates the tgsi code from mesa, it introduces
changes necessary to deal with tessellation and doubles.
It also drops an unused saturate feature, which we didn't
use anyways.
I'm not sure this is 100% complete, piglit fbo-alpha now passes.
This was a guess as to why gnome-shell was broken, but I don't think
it was the correct one.
the scaling stuff needs to happen in the geom shader instead
of the vertex shader if a geom shader is present.
