From a16ae77185813522d9b82372e18e2727eb2794b6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nicolai=20H=C3=A4hnle?= Date: Tue, 2 May 2017 17:46:12 +0200 Subject: [PATCH] radeonsi: get rid of secondary input/output word MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit By keeping track of fewer generics, everything can fit into 64 bits.
