From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Borkmann Subject: [PATCH net-next] sparc: bpf_jit_comp: add XOR instruction for BPF JIT JIT Date: Mon, 24 Sep 2012 23:57:54 +0200 Message-ID: <20120924215753.GA31312@thinkbox> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: netdev@vger.kernel.org To: davem@davemloft.net Return-path: Received: from mail-wg0-f44.google.com ([74.125.82.44]:51622 "EHLO mail-wg0-f44.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750927Ab2IXV56 (ORCPT ); Mon, 24 Sep 2012 17:57:58 -0400 Received: by wgbdr13 with SMTP id dr13so4093340wgb.1 for ; Mon, 24 Sep 2012 14:57:57 -0700 (PDT) Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-ID: This patch is a follow-up for patch "filter: add XOR instruction for use with X/K" that implements BPF SPARC JIT parts for the BPF XOR operation. Signed-off-by: Daniel Borkmann --- I don't own a SPARC machine. This code is untested and uncompiled, but following the other instructions, this should integrate cleanly. Can someone confirm that?
