From: Francisco Jerez Date: Fri, 2 Sep 2016 05:37:57 +0000 (-0700) Subject: i965/vec4: Assert that pull constant load offsets are 16B-aligned. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6d861968ca2f3e196ce4bcad4f2b91b5a63ce0f1;p=mesa.git 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.
