From ce086ebd89633d8d967cd65bacf5b05c1ac555ed Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 16 Oct 2012 17:21:39 -0700 Subject: mesa: Throw an error for a new query on an already-active query target. There's a similar test below, but it's not the same: that one checks whether this query object is already active (potentially on another target).
