From: Dave Airlie <airl...@redhat.com> This gets the ssao demo from 400->440 fps on radv with the previous patch.
Now the demo does a 0->32 loop across a ubo with 32 members, I don't know if we still have that sort of information available about the UBO in question at this stage. Maybe someone more familiar with spir-v/nir can tell if we can access that info then we can force a loop unroll like we do for var arrays.
