With this tool, we can explore the intricacies of low-level programming and gain insights into how binaries are structured and executed.\n\nYou might find [our memo](MEMO.md) helpful if you're new to X86-64 and assembly (like us).\n\n## Install\n\nTo get started with MyDisassembler, follow these simple steps:\n\n- Clone the Repository:\n\n```bash\ngit clone https://github.com:Koukyosyumei/MyDisassembler.git\n```\n\n- Build the Project:\n\n```bash\ncd MyDisassembler\n./script/build.sh\n```\n\n## Usage\n\nOnce installed, you can use MyDisassembler to disassemble binary files and delve into their assembly code. Here's how you can use it:\n\n```bash\n./build/script/mydisas example/jmp.o\n```\n\n```yaml\nsection: .text ----\n\n40 \u003c_start\u003e:\n 40: mov  eax 0x00000000                      ( b8 0 0 0 0 )\n 45: cmp  eax 0x00                            ( 83 f8 0 )\n 48: jz 4e \u003czero_label\u003e ; relative offset = 4 ( 74 4 )\n 4a: jmp 52 \u003cend_label\u003e ; relative offset = 6 ( eb 6 )\n 4c: jmp 40 \u003c_start\u003e ; relative offset = -14  ( eb f2 )\n\n4e \u003czero_label\u003e:\n 4e: push  rsp                                ( 54 )\n 4f: xor  eax eax                             ( 31 c0 )\n 51: ret                                      ( c3 )\n\n52 \u003cend_label\u003e:\n 52: push  rdi                                ( 57 )\n 53: xor  ecx ecx                             ( 31 c9 )\n 55: ret                                      ( c3 )\n-------------------\nDone!\n```\n\n## Features\n\n- Implemented entirely from scratch in C++\n- Supports both linear sweeping and recursive descent disassembly strategies\n- Handles most basic operations with precision\n- Capable of parsing ELF headers for deeper analysis\n\n## Future Improvements\n\n- Expand test coverage for enhanced reliability\n- Add support for VEX Prefix\n- Incorporate additional instructions, including floating-point operations\n- Introduce support for AT\u0026T syntax\n\nFeel free to contribute to MyDisassembler and make it even better!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkoukyosyumei%2Fmydisassembler","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkoukyosyumei%2Fmydisassembler","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkoukyosyumei%2Fmydisassembler/lists"}
