/// This code based 'dct64_3dnow.s' by Syuuhei Kashiyama
/// <squash@mb.kcom.ne.jp>,only some types of changes have been made:
///
/// - added new opcode PSWAPD
/// - added new opcodes PSWAPD, PFPNACC
/// - decreased number of opcodes (as it was suggested by k7 manual)
/// (using memory reference as operand of instructions)
/// - Phase 6 is rewritten with mixing of cpu and mmx opcodes
/// - change function name for support 3DNowEx! automatic detect
///
/// note: because K7 processors are an aggresive out-of-order three-way
