Author: Roland Scheidegger <srol...@vmware.com> Date: Wed Dec 31 17:39:57 2014 +0100 gallium/util: fix crash with daz detection on x86 The code used PIPE_ALIGN_VAR for the variable used by fxsave, however this does not work if the stack isn't aligned. Hence use PIPE_ALIGN_STACK function decoration to fix the segfault which can happen if stack alignment is only 4 bytes. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=87658.
