From 07fabd1cd1f2173d93cb1b3962da7d11ca80c569 Mon Sep 17 00:00:00 2001
From: Dan Everton <dan@iocaine.org>
Date: Mon, 9 Jul 2007 11:18:10 +0000
Subject: ICONST_ATTR most constant tables in Speex. Results in a 10%
 improvement on Coldfire (200% to 220% realtime). Almost certainly not the
 best use of IRAM, but it works now.
