From: Bruce Cherniak Date: Tue, 24 May 2016 20:00:17 +0000 (-0500) Subject: swr: [rasterizer] Correctly select optimized primitive assembly. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c8835a592471a0238e296f6529b5dadb431cc622;p=mesa.git swr: [rasterizer] Correctly select optimized primitive assembly. Indexed primitives were always using cut-aware primitive assembly, whether primitive_restart was enabled or not. Correctly pass down primitive_restart and select optimized PA when possible.
