From 44960ef918fff24cf7e49f4c89e845709aae3541 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 9 Aug 2013 18:54:24 -0700 Subject: [PATCH] i965/fs: Re-enable global copy propagation. I believe the data flow analysis actually works now, and it should be safe to re-enable global copy propagation. It even does things now.
