From 63ed11cde9987e438bf28ef74879e2700971eb26 Mon Sep 17 00:00:00 2001 From: Tom Stellard Date: Fri, 26 Aug 2016 19:49:13 +0000 Subject: radeonsi: Don't use global variables for tess lds MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We were allocating global variables for the maximum LDS size which made the compiler think we were using all of LDS, which isn't the case.
