From: Jason Ekstrand Date: Tue, 9 May 2017 19:34:10 +0000 (-0700) Subject: i965/vec4: Set VERT_BIT_EDGEFLAG based on the VUE map X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d2fe804d1890774828a5481f5873743d71d37c2a;p=mesa.git i965/vec4: Set VERT_BIT_EDGEFLAG based on the VUE map We also add a nice little comment to make it more clear exactly what happens with the edge flag copy.
