Hi Dave,

When I run all the piglit tests related to tessellation, the following failed:

spec/arb_tessellation_shader/arb_tessellation_shader-minmax
spec/arb_tessellation_shader/built-in-constants/gl_maxtesspatchcomponents
spec/arb_tessellation_shader/execution/tes-input/tes-input-gl_clipdistance
spec/arb_tessellation_shader/execution/variable-indexing/tcs-tes-array-in-struct
spec/ext_transform_feedback/tessellation triangle_fan flat_first

On the QEMU console, I can see lots of "mismatch in number of interps 1 1".

I didn't investigate more.

Elie.
