Am I right to think this is a verbatim repost from http://thread.gmane.org/gmane.comp.bios.tianocore.devel/12482 ? If so, then I think Olivier should review it and then just go ahead and commit it, preferably with: Tested-by: Wei Huang <w...@redhat.com> based on Wei's message with Message-Id <54f740b4.3050...@redhat.com>. Unfortunately I can't find that email at the moment in the gmane archive, but I'm attaching it. Thanks Laszlo
--- Begin Message ---I can confirm that this patch fixes my problem. The machine is a native AArch64 server, with Fedora GCC 4.8.3.
