Subject: [PATCH 1/8] remove volatile keyword from clflush.
Date: Tue, 4 Dec 2007 14:06:21 -0200
Message-ID: <11967843943958-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <11967843881946-git-send-email-gcosta@redhat.com>
the p parameter is an explicit memory reference, and is
enough to prevent gcc to being nasty here. The volatile
seems completely not needed.
