/// Replacement of dct36() with AMD's 3DNowEx(DSP)! SIMD operations support
///
/// 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
/// superscalar ones instruction order is not significand for them.

/ 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).
/
/ by KIMURA Takuhiro <kim@hannah.ipc.miyakyo-u.ac.jp> - until 31.Mar.1999
/ <kim@comtec.co.jp> - after 1.Apr.1999
