From 9ac55e8219e1f6abeab3c779c8fe710c2bc25f2b Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 6 Jul 2017 17:54:49 -0600 Subject: [PATCH] mesa: finish implementing glPrimitiveRestartNV() for display lists If we try to build a display list with just a glPrimitiveRestartNV() call, we'd crash because of a null GLvertexformat::PrimitiveRestartNV pointer. This change fixes that case. The previous patch fixed the case of calling glPrimitiveRestartNV() inside a glBegin/End pair. v2: minor clean-up in save_PrimitiveRestartNV(), per Charmaine.
