Subject: [PATCH 9/18] powerpc: change mtcrf to use real register names
Date: Thu, 21 Jun 2012 12:04:36 +1000 [thread overview]
Message-ID: <20120621020436.467F8D431D9@localhost.localdomain> (raw)
In-Reply-To: <1340244266.960241.475925824909.qpush@ale>
mtocrf define is just a wrapper around the real instructions so we can
just use real register names here (ie. lower case).
Also remove braces in macro so this is possible.
