From 6d861968ca2f3e196ce4bcad4f2b91b5a63ce0f1 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Thu, 1 Sep 2016 22:37:57 -0700 Subject: [PATCH] i965/vec4: Assert that pull constant load offsets are 16B-aligned. Non-16B-aligned pull constant loads are unlikely to be particularly useful given that you can get roughly the same effect by using swizzles on the result.
