From 1614c39a8fc205d7b1cb5b16737c233fbcc5b678 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 23 Sep 2015 00:30:23 -0400 Subject: [PATCH] st/mesa: keep track of saturated writes when eliminating dead code MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It doesn't matter whether a write is saturated or not, in another implementation it might even have been a separate opcode. This code was most likely copied from the copy-propagation pass (where one does have to distinguish saturation).
