From 9d08756ac7d27b5a392d17c2a91a55cec6edab5d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sun, 18 Aug 2013 18:06:13 -0700 Subject: [PATCH] i965/fs: Add code to print out global copy propagation sets. This was invaluable when debugging the global copy propagation algorithm. We may as well commit it in case someone needs to print out the sets in the future.
