From d7d23aee4b41de64781fe249ca9a99a9166b097d Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Sun, 11 Dec 2016 23:37:30 +0100 Subject: [PATCH] gallivm: (trivial) handle non-aligned fetch for lp_build_fetch_rgba_soa soa fetch so far always assumed that data was aligned. However, we want to use this for vertex fetch, and data might not be aligned there, so handle it in this path too (basically just pass through alignment through to other functions). (It looks like it wouldn't work for for cached s3tc but this is no different than with AoS fetch.)
