From: Dave Airlie Date: Tue, 18 Apr 2017 23:13:06 +0000 (+1000) Subject: radv/meta: refactor out some common shaders. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=03a2ca63562b73d36658e43c0d7d77150421be60;p=mesa.git radv/meta: refactor out some common shaders. The vs vertex generate and fs noop shaders are used in a few places, so refactor them out.
