Subject: [PATCH 5/9] of: put default string compare and #a/s-cell values into common header
Date: Sat, 13 Feb 2010 09:02:53 -0700 [thread overview]
Message-ID: <20100213160252.4767.94582.stgit@angua> (raw)
In-Reply-To: <20100213154838.4767.83881.stgit@angua>
Most architectures don't need to change these. Put them into common
code to eliminate some duplication
