From 337f21bc356a89a9c755aebabb64ba381a59e39b Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Wed, 5 Jun 2013 15:38:27 +0100 Subject: util: Use sizeof(void *) rather than 0 as the fallback cache line size Without this, llvmpipe ends up giving a zero size to all uncompressed textures on non-x86 systems, since align() cannot handle a 0 alignment.
