	This code based 'dct36_3dnow.s' by Syuuhei Kashiyama
	<squash@mb.kcom.ne.jp>,only two types of changes have been made:

	- remove PREFETCH instruction for speedup
	- change function name for support 3DNow! automatic detect

	You can find Kashiyama's original 3dnow! support patch
	(for mpg123-0.59o) at
	http://user.ecc.u-tokyo.ac.jp/~g810370/linux-simd/ (Japanese).
