Subject: r600g: write proper output prim type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cda63db780512f7ca81f5e7973120d335e576ad6;p=mesa.git

r600g: write proper output prim type

Vadim's code derived it from the info.mode, but it needs
to be takes from the geometry shader output primitive.
