Branch: master
Commit: 2d13b5ac81a8c2aa1f36be7e3350b12fbdbd65e8
URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=2d13b5ac81a8c2aa1f36be7e3350b12fbdbd65e8

ilo: add a pass to finalize ilo_ve_state
Add finalize_vertex_elements() to finalize ilo_ve_state. This fixes a
potential issue with URB entry allocation for VS and move the complexity of
gen6_3DSTATE_VERTEX_ELEMENTS() to the new function.
