From 86e32fdce7c6582a52b9468106714779d871c773 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Mon, 25 Jun 2012 13:33:16 +0000 Subject: [PATCH] powerpc: Change mtcrf to use real register names 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.
