Subject: [PATCH 2/4] x86: Move instruction decoder data into header
Date: Mon, 14 Apr 2014 13:44:08 -0400 [thread overview]
Message-ID: <1397497450-6440-2-git-send-email-sasha.levin@oracle.com> (raw)
In-Reply-To: <1397497450-6440-1-git-send-email-sasha.levin@oracle.com>
Right now we generate data for the instruction decoder and place it
as a code file which gets #included directly (yuck).
Instead, make it a header which will also be usable by other code
that wants to use the data in there.
