From 9048adbd246c725ae80942b6b56a742ad02295dc Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 16 May 2020 23:59:40 -0400 Subject: freedreno/ir3: avoid applying (sat) on bary.f This causes failures on a3xx resulting in the non-sensical dEQP failures on packUnorm2x16. The same test uses ldlv on a4xx+, so just disallow (sat) on bary.f on all generations.
