From 04d35714a6e10f96f8a216c626f46fdfbc2e5c1f Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 11 Feb 2010 16:54:48 -0700 Subject: [PATCH] svga: check min_index, max_index before assertions It's possible for min_index and max_index to be ~0 if the min/max values were not actually set or computed in the state tracker. Skip some assertions in that case. This only effects the debug build error checking.
