Bug detailed description:
-------------------------
It fails on sandybridge.It passes on ivybridge and haswell.
Following cases also fail on sandybridge:
spec_glsl-1.40_execution_textureSize_fs-textureSize-isamplerBuffer
spec_glsl-1.40_execution_textureSize_fs-textureSize-usamplerBuffer
spec_glsl-1.40_execution_textureSize_vs-textureSize-isamplerBuffer
spec_glsl-1.40_execution_textureSize_vs-textureSize-samplerBuffer
spec_glsl-1.40_execution_textureSize_vs-textureSize-usamplerBuffer

output:
Probe at (10,10)
  Expected: 0.650000 0.000000 0.000000 1.000000
  Observed: 0.011765 0.000000 0.000000 1.000000

Reproduce steps:
----------------------------
1. xinit
2. ./bin/textureSize 140 fs samplerBuffer -auto -fbo
Comment 1 Samuel Iglesias Gonsálvez 2014-10-01 06:28:22 UTC
The textureSize() call with samplerBuffer sampler type returns undefined results in SandyBridge. In the source code, this is translated to a 'resinfo' message type for SURFTYPE_BUFFER but it's undefined in SNB (see SNB's PRM documentation vol4_part1, page 141).

It has been confirmed in the mailing list by an Intel engineer: http://lists.freedesktop.org/archives/mesa-dev/2014-September/068803.html
