From: Dave Airlie Date: Sun, 5 Mar 2017 23:58:45 +0000 (+1000) Subject: radv/ac: move to new image intrinsics. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e27fdbcb4c951bba0649cf60f2ae377f842267bb;p=mesa.git radv/ac: move to new image intrinsics. This hooks up radv to the new image intrinsic builders.
