From 8e44f4117a9c73ea336063f7c2fbf4d6a592eeae Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 6 Feb 2013 13:09:46 -0800 Subject: llvmpipe: refactoring of visibility counter handling There can be other per-thread data than just vis_counter, so pass a struct around instead (some of our non-public code uses this already and this difference is a major cause of merge pain).
