From aedc0aab19c233cc084211959ef2b6be1c500bb7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg=20Kristensen?= Date: Tue, 20 Oct 2015 23:07:56 -0700 Subject: [PATCH] i965/fs: Use unsigned immediate 0 when eliminating SHADER_OPCODE_FIND_LIVE_CHANNEL MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The destination for SHADER_OPCODE_FIND_LIVE_CHANNEL is always a UD register. When we replace the opcode with a MOV, make sure we use a UD immediate 0 so copy propagation doesn't bail because of non-matching types.
