<pre>Okay, talked to idr. The problem seems to be that the not(8) in his example
can't be propagated into the and(8) because the types are signed...? I don't
see any code in brw_fs_copy_propagate.cpp to handle this, so I don't think it's
related to the argument types.
But yeah, we should be propagating NOT into logic operations.</pre>
