Hi Xavier,

Sorry for the late reply.

The assertion in pipe_reference can be fixed quite easily I think. There is
pipe_*_reference missing somewhere.

Concerning fp-long-alu, there are new CAPs for shader limits which should be
filled out but I don't know what values to put there. If the two get fixed,
it will hopefully be just 2 new failures along with 3 that pass.

Here is the tree with the commit reverted:

git://anongit.freedesktop.org/~mareko/mesa nvfx-next-6b-notemps

It is compile-tested so if it does not work, there is nothing I can do about
it.
