Subject: aco/ngg: Schedule position exports of NGG VS/TES.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e4da482d9e94c2ca5935c8cbb864287aa192778a;p=mesa.git

aco/ngg: Schedule position exports of NGG VS/TES.

Similarly to the HW VS stage, the HW NGG GS stage also
benefits from executing these exports as early as possible.
