From: Eric Anholt Date: Mon, 13 Feb 2012 18:00:14 +0000 (-0800) Subject: i965: Make the userclip flag for the VUE map come from VS prog data. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9f3d3216cf25d8ffed4d72fbce6feacbc2990e4b;p=mesa.git i965: Make the userclip flag for the VUE map come from VS prog data. This reduces recomputation of state based on non-clipping-related transform changes, and is a step toward removing VUE map recomputation.
