JMPLABEL

Jump Label このopcodeに対し to_bytes() メソッドを呼び出すと， [REX-Prefix, opcode] が返されます． 自作アセンブラでこのバイト列に対し imm32(0) を追加して， あとから相対オフセットを計算するといいと思います．

JELABEL

Jump Equal Label このopcodeに対し to_bytes() メソッドを呼び出すと， [REX-Prefix, opcode1, opcode2] が返されます． 自作アセンブラでこのバイト列に対し imm32(0) を追加して， あとから相対オフセットを計算するといいと思います．

LEAR64FROMSTRADDR

スタティックリンクで使用される， lea rax, .LS1 のような命令です． このopcodeに対し to_bytes() メソッドを呼び出すと， [REX-Prefix, opcode, ModRM] が返されます． 自作アセンブラでは let mut base_bytes = inst.to_bytes(); base_bytes.append(&mut vec![0x25, 0x00, 0x00, 0x00, 0x00]) のように， データセグメントを用いるプリフィックスと，再配置でアドレスを書き込むためのパディングを追加するといいでしょう． そして再配置シンボルを定義して，リンク時に文字列のアドレスを書き込むといいと思います．
