//命令の処理
// 第1オペコードの上位10bitで分岐する
// 分岐方法
// XEiJ.IRP_STATIC
// 手順
// 命令の処理をstaticメソッドに書く
// switch(XEiJ.regOC>>>6)で分岐してirpXXX()で呼び出す
// Javaはメソッドのサイズに制限があるためswitch(XEiJ.regOC>>>6)の中にすべての命令の処理を書くことができない
// C言語のときはswitchの中にすべての命令の処理を書くことができる
// 利点
// 速い
// XEiJ.IRP_ENUM_DIRECT
// 手順
// 命令の処理をenum bodyのメソッドに書く
// switch(XEiJ.regOC>>>6)で分岐してIRP.XXX.exec()で呼び出す
// 欠点
// XEiJ.IRP_STATICよりも遅い
// staticなメソッドを直接呼び出せることに変わりないはずだが、インライン展開などの最適化が弱くなるのかも知れない
// XEiJ.IRP_STATICと共存させようとすると命令の処理を2回書かなければならず管理が面倒になる
// XEiJ.IRP_ENUM_INDIRECT
// 手順
// 命令の処理をenum bodyのメソッドに書く
// XEiJ.regOCの上位10bit→enum値の配列を用意する
// IRPMAP.IRPMAP0[XEiJ.regOC>>>6].exec()で呼び出す
// C言語のときは関数を指すポインタの配列が使えるのでIRPMAP0[XEiJ.regOC>>>6]()で済む
// 利点
// 命令の処理を動的に組み替えることができる
// 欠点
// XEiJ.IRP_ENUM_DIRECTよりも遅い
// 配列参照による多分岐とenum bodyのメソッドの動的呼び出しによる多分岐の2段階になる
// XEiJ.IRP_STATICと共存させようとすると命令の処理を2回書かなければならず管理が面倒になる
// enum値の配列の初期化コードが大きくなるのでクラスを分ける必要がある
