Author: Rhys Perry <[email protected]> Date: Mon Nov 18 21:00:17 2019 +0000 aco: fix block_kind_discard s_andn2 definition to exec Improves generated code of dEQP-VK.graphicsfuzz.disc-and-add-in-func-in-loop because a loop exit phi can then be fixed to exec, removing copies and improving jump threading. No pipeline-db changes.
