[Mesa-dev] [PATCH v3 3/9] i965/state: Support multiple pipelines in brw->num_atoms
Jordan Justen

Fri Mar 20 17:28:58 PDT 2015
brw->num_atoms is converted to an array, but currently just an array
of length 1.
Adds brw_copy_pipeline_atoms which copies the atoms for a pipeline,
and sets brw->num_atoms[p] for pipeline p.
v2:
* Rename brw->atoms[] to render_atoms
* Rename brw_add_pipeline_atoms to brw_copy_pipeline_atoms
* Rename brw_pipeline_first_atom to brw_get_pipeline_atoms
