From: Dave Airlie Date: Fri, 15 Sep 2017 02:55:50 +0000 (+1000) Subject: mesa/bufferobj: consolidate some codepaths between ubo/ssbo/atomics. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=35ac13ed32cc954825549f4c88d0c3d927985817;p=mesa.git mesa/bufferobj: consolidate some codepaths between ubo/ssbo/atomics. These are 90% the same code, consolidate them into a couple of common codepaths.
