From e5ec5aef2be4d667a1f28f0ee0105dd6dc204732 Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Mon, 23 Sep 2013 17:29:39 -0400 Subject: llvmpipe: align the array used for subdivived vertices When subdiving a triangle we're using a temporary array to store the new coordinates for the subdivided triangles. Unfortunately the array used for that was not aligned properly causing random crashes in the llvm jit code which was trying to load vectors from it.
