Description Clayton Craft 2018-08-24 16:05:21 UTC
The following piglit tests are failing for BXT, SKL, KBL, CFL, and GLK platforms when running 32bit mesa:

piglit.spec.intel_shader_atomic_float_minmax.execution.ssbo-atomiccompswap-float-negative-zero
piglit.spec.intel_shader_atomic_float_minmax.execution.ssbo-atomicmin-float-nan 
piglit.spec.intel_shader_atomic_float_minmax.execution.ssbo-atomicmax-float-nan

It has been bisected to this commit:

So... only those three tests fail, and they only fail on 32-bit?  I'll try to reproduce that locally.  Weird.
