It is intended as practical guidance for developers, not as a vendor-verified ISA specification.\n\n## Project Information\n\n- Project repository: \u003chttps://github.com/nihui/unofficial-mips-loongson-intrinsics-guide\u003e\n- Documentation site: \u003chttps://nihui.github.io/unofficial-mips-loongson-intrinsics-guide/\u003e\n- Inspired by and modeled after: \u003chttps://github.com/jiegec/unofficial-loongarch-intrinsics-guide\u003e\n- This guide was generated with assistance from OpenAI GPT-5 Codex.\n\n## Build\n\nGenerate the Markdown pages from the headers:\n\n```sh\npython3 tools/generate_docs.py\n```\n\nBuild the static HTML site:\n\n```sh\npython3 -m mkdocs build\n```\n\nCheck that all public intrinsics parsed from the headers are present in `docs/`:\n\n```sh\npython3 check.py\n```\n\nServe locally:\n\n```sh\npython3 -m mkdocs serve\n```\n\nThe source headers under `include/` retain their original GCC copyright notices.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnihui%2Funofficial-mips-loongson-intrinsics-guide","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnihui%2Funofficial-mips-loongson-intrinsics-guide","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnihui%2Funofficial-mips-loongson-intrinsics-guide/lists"}
