Subject: [Qemu-devel] [PATCH 10/10] Remove r0 from the allocation pool on ppc/ppc64
Date: Sat, 28 Mar 2009 14:02:47 -0700 [thread overview]
Message-ID: <1238274167-7890-11-git-send-email-froydnj@codesourcery.com> (raw)
In-Reply-To: <1238274167-7890-1-git-send-email-froydnj@codesourcery.com>
r0 is used as a temporary for forming 32-bit constants; it also has
unexpected behavior when used as a base register in load and store
instructions.
