From 323e4bff799a657632c5777c8be6e306202953af Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 14 Jul 2011 08:09:21 -0600 Subject: [PATCH] mesa: split _mesa_reference_program() into hot/cold paths. inline the hotpath of the reference remaining the same. This shouldn't penalise the slow path at all but improve the hot path so we don't have to jump to the function. It also moves some assert checks under an #ifndef NDEBUG. Minor clean-ups added by Brian.
