From a68dd47b911053995ae387afcdc7fffe82e57420 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Sun, 9 Sep 2018 13:40:02 -0700 Subject: [PATCH] nir/algebraic: Simplify fsat of fsign These allows us to not support fsign.sat in the Intel compiler backend, and that will simplify some later changes. No shader-db changes on any Intel platform.
