/// This code based 'dct36_3dnow.s' by Syuuhei Kashiyama
/// <squash@mb.kcom.ne.jp>,only some types of changes have been made:
///
///  - added new opcode PSWAPD
///  - change function name for support 3DNowEx! automatic detect
///
/// note: because K7 processors are an aggresive out-of-order three-way

/ dct36_3dnow.s - 3DNow! optimized dct36()
/
/ 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).
