From d5bdce1142d23e68404487e107532fd8dd545b1a Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 1 May 2013 19:15:32 -0600 Subject: [PATCH] mesa: simplify save_Begin() error checking The old code was hard to understand and not entirely correct. Note that PRIM_INSIDE_UNKNOWN_PRIM is no longer set anywhere so we'll be able to remove that next.
