From fb6ecca0a556dcca1f77bfb84a835e2b9c2e2e6a Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 2 Mar 2011 14:08:59 +1000 Subject: rgtc: fix issues with compressor and signed types. With signed types we weren't hitting this test however the comment stating this doesn't happen often doesn't apply when using signed types since an all 0 block is quite common which isn't abs min or max. this fixes the limits correctly again also.
