From 09e46f99ad465ab253de3fc321f39062cfbe1984 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Tue, 19 Jul 2016 15:13:51 +1000 Subject: i965: bring back type_size_vec4_times_4() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We will use this for output varyings. To make component packing simpler we will just treat all varyings as vec4s.
