Subject: nvc0: Set winding order regardless of domain.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=65d3f85eb3efb326a826c2db0225340d5421a389;p=mesa.git

nvc0: Set winding order regardless of domain.

Quads need to respect winding order, too - not just triangles.

Fixes rendering in GFXBench 4.0's tessellation benchmark.
