+传统移植方式依赖人工逐一处理，效率低下且经验难以复用。本方案提出一套 **自动化、标准化、可复用** 的软件包移植体系，结合 AI Agent（OpenClaw）辅助，实现从源码获取到 RPM 产出全流程的自动化。 + +### 1.2 目标 + +| 维度 | 目标 | +|------|------| +| **效率** | 将单个软件包的移植周期从人日均级降至小时级 | +| **质量** | 移植后的包通过相同的测试套件，行为与源架构一致 | +| **可复用** | 每个移植决策可记录、可回溯、可复现 | +| **规模化** | 支撑成百上千个软件包的批量移植 | +| **标准化** | 统一的 RPM spec 模板、构建流程、质量门禁 | + +### 1.3 核心原则 + +1. **基线先行**: 任何移植必须先在 x86_64 上建立参考构建基线 +2. **最小侵入**: 移植修改仅限于解决架构差异，不破坏原有架构兼容性 +3. **可追溯**: 每处修改通过 Git 跟踪，每步决策有文档记录 +4. **自动化优先**: 能脚本化的不手动作，能 Agent 处理的不人工介入 +5. **知识沉淀**: 每完成一个移植，将经验结构化为可检索的数据 + +--- + +## 2. 目标架构与环境 + +### 2.1 硬件平台 + +```

+传统移植方式依赖人工逐一处理，效率低下且经验难以复用。本方案提出一套 **自动化、标准化、可复用** 的软件包移植体系，结合 AI Agent（OpenClaw）辅助，实现从源码获取到 RPM 产出全流程的自动化。 + +### 1.2 目标 + +| 维度 | 目标 | +|------|------| +| **效率** | 将单个软件包的移植周期从人日均级降至小时级 | +| **质量**

按优先级顺序查找构建系统文件。如果只有Makefile，直接阅读Makefile目标。如果是CMake项目，运行 `cmake -B build && cmake --build build`。如果完全无法识别构建系统，**暂停并询问用户**。 + +### Q: X86-64参考构建失败了，是否还要继续LoongArch64移植？ +A: **不要**。先在X86-64上解决构建问题，区分这是项目本身的通用问题还是架构问题。如果确认是项目本身的Bug，记录后修复并重新构建。 + +### Q: 用户要求直接修改源码适配LA64，但没有要求X86-64基线怎么办？ +A: **必须执行初始提交**。然后向用户说明基线原则，询问是否先进行X86-64参考构建。如果用户坚持跳过，记录此决策并继续，但需在报告中注明缺少基线对比。 + +### Q: 我通过SSH连接到了LoongArch64机器，如何确认？ +A: 执行 `uname -m` 应输出 `loongarch64`；执行 `gcc -dumpmachine` 应输出 `loongarch64-linux-gnu`。 + +### Q: 构建产物（如.o文件、可执行文件）应该提交到Git吗？ +A: **不应该**。确保 `.gitignore` 已包含build目录。如果项目没有.gitignore，创建一个。 + +## 9. 特殊项目类型：JIT/Copy-and-Patch 编译器移植 + +### 9.1 适用场景 + +Python 3.14 引入的 Copy-and-Patch JIT、JavaScript/WebAssembly 引擎（如 V8、SpiderMonkey）、LuaJIT、动态编译优化器等，涉及以下技术点： + +| 领域 | 特殊要求 | +|------|---------| +| 运行时代码生成 | 需要 LA64 指令编码知识（固定4字节对齐） | +| ELF 重定位 | 需要了解 LA64 重定位类型（R_LARCH_B26, R_LARCH_GOT_PC_HI/LO12 等） | +| 调用约定 | `preserve_none`/`preserve_all` 等非标准 CC 可能在 LA64 缺失 | +| 内联汇编 | 需要替换 X86-64 特有的指令序列 | +| TCO/尾调用 | LA64 的尾调用使用 `b` 而非 `bl`（不修改 $ra） | + +### 9.2 常见挑战 + +1. **LLVM 依赖陷阱**：JIT 通常依赖新版本 LLVM 提供的功能（如 `preserve_none`）。系统 LLVM 版本可能过旧，需从源码构建 LLVM 并为 LA64 后端打补丁。 + +2. **调用约定差异**：LLVM 的 `preserve_all`/`preserve_none` calling convention 在 X86-64 和 AArch64 有完整支持，但 LA64 是社区添加的较新后端，可能缺失。需在 `LoongArchCallingConv.td` 中定义 CSR，在 `LoongArchRegisterInfo.cpp` 中注册。 + +3. **重定位类型不匹配**：X86-64 使用 PC32、GOTPCREL 等重定位类型。LA64 使用 B26、GOT_PC_HI20/GOT_PC_LO12、PCALA_HI20/PCALA_LO12 等，需逐一适配。 + +4. **GCC/LLVM 调用约定不一致**：如果解释器由 GCC 编译、JIT 代码由 LLVM 生成，两者可能使用不同的默认调用约定。入口点函数需使用标准 CC 兼容两者。 + +5. **尾调用优化陷阱**：`return call(args)` 可能被编译器优化为 `b`（尾调用），跳过 stack frame 的 epilogue（callee-saved 寄存器恢复）。当 caller 是标准 CC、callee 是 `preserve_none` 时，这是个隐蔽的 bug。 +

+> 在执行类似移植任务前，请先查阅本节，避免重复犯错。 + +## 1. 移植流程陷阱 + +### 陷阱 1.1：跳过X86-64参考构建 + +**问题**：用户催促或Agent自信，直接进入LoongArch64移植，发现构建失败，却无法判断是项目本身的问题还是架构差异。 + +**后果**： +- 浪费时间在修复项目本身的通用Bug上 +- 无法区分"移植问题"和"项目问题" +- 无法验证移植后的行为是否与X86-64一致 + +**预防措施**： +- **严格执行阶段2**：任何移植必须先完成X86-64参考构建 +- 记录X86-64的完整构建日志和测试输出 +- 如果X86-64构建失败，先解决后再移植 + +--- + +### 陷阱 1.2：忘记初始提交 + +**问题**：直接修改源码后才发现没有Git仓库，无法区分原始代码和修改。 + +**后果**： +- 无法生成干净的移植补丁 +- 无法回溯原始状态 +- 可能丢失修改 + +**预防措施**： +- **强制检查**：每次处理新项目，第一步检查 `.git` 目录 +- 使用检查脚本（见 `operations/safe-operations.md` 第7节） + +--- + +### 陷阱 1.3：构建产物跨架构污染 + +**问题**：在X86-64上构建了项目，然后直接在LoongArch64上继续构建，没有清理build目录。 + +**后果**： +- 链接器可能混用X86-64和LoongArch64的目标文件 +- 出现难以理解的链接错误 +- 可能链接出无法运行的混合架构二进制 + +**预防措施**： +- **切换架构时清理build目录**：`rm -rf build/ && mkdir build` +- 使用 `file` 命令验证构建产物的架构：`file build/src/some_binary` +- 推荐在CMake/Make中使用独立目录：`-B build-x86_64` 和 `-B build-loongarch64` + +--- + +## 2. 源码修改陷阱 + +### 陷阱 2.1：破坏X86-64兼容性 + +**问题**：为适配LoongArch64修改了通用代码，导致X86-64上无法编译或行为改变。 + +**案例**： +```c +// 错误：直接修改通用代码 +int pointer_size = 8; // 原来 sizeof(void*) + +// 正确：使用条件编译 +#ifdef __loongarch__ +// LA64特定代码 +#else +// 其他架构代码 +#endif +``` + +**预防措施**： +- 使用条件编译隔离架构差异：`#ifdef __loongarch__` / `#if defined(__loongarch64)` +- 修改后回到X86-64验证编译（如可能） +- 优先使用标准C/C++类型（`uintptr_t`, `size_t`）而非假设指针宽度 + +--- + +### 陷阱 2.2：忽视字节序差异 + +**问题**：LoongArch64可以配置为大端或小端，但通常为小端（与X86-64相同）。如果代码假设了字节序，可能在特定配置下出错。 + +**预防措施**： +- 如果项目已有字节序处理，确认是否覆盖LoongArch64 +- 使用标准宏检测：`#include ` 后使用 `__BYTE_ORDER__` +- 不要假设LoongArch64的字节序 + +--- + +### 陷阱 2.3：内联汇编硬编码 + +**问题**：项目包含X86-64特有的内联汇编（SSE/AVX指令、CPUID等），直接移植到LoongArch64。 + +**常见场景**： +- `cpuid` 指令获取CPU信息 → 需替换为LA64等价物或系统调用 +- `rdtsc` 读取时间戳 → 替换为LA64 `rdtime` 或标准 `clock_gettime` +- 原子操作汇编 → 替换为C11 `_Atomic` 或GCC内置函数 + +**预防措施**： +- 查找所有 `__asm__`, `asm()`, `__asm` 出现位置 +- 优先考虑使用编译器内置函数而非内联汇编 +- 如果没有LA64等价物，使用条件编译提供回退实现 + +--- + +### 陷阱 2.4：LA64 指令编码假设（从 AArch64 移植） + +**问题**：将 AArch64 的指令编码逻辑直接搬到 LA64。 + +**典型场景**： + +1. **`ADRP` → `PCADDU12I` 假页对齐** + - AArch64 的 `ADRP` 会清除 PC 的低12位（页对齐），然后 `LDR` 用 `target & 0xFFF` 作为偏移 + - LA64 的 `PCADDU12I` **不做页对齐**，PC 的低12位保留 + - 错误做法：`imm20 = (page_of_target − page_of_PC) >> 12, imm12 = target & 0xFFF` + - 正确做法：`diff = target − PC, imm20 = diff >> 12, si12 = diff & 0xFFF`（处理符号扩展） + +2. **`ALSL.D` 的移位量** + - `ALSL.D rd, rj, rk, sa` 计算 `rd = rk + (rj << sa)` + - `sa` 是**直接移位量**，不是 `sa+1` + - 验证：`alsl.d $a0, $a1, $a2, 1` = `$a0 = $a2 + ($a1 << 1)` + +### 陷阱 2.5：指针与整数转换 + +**问题**：假设 `sizeof(long) == sizeof(void*)`，在ILP32和LP64模型中不同。 + +| 数据模型 | int | long | long long | pointer | +|----------|-----|------|-----------|---------| +| X86-64 LP64 | 32 | 64 | 64 | 64 | +| LoongArch64 LP64 | 32 | 64 | 64 | 64 | +| X86 ILP32 | 32 | 32 | 64 | 32 | + +**预防措施**： +- 使用 `` / `` 中的定宽类型 +- 指针转整数用 `uintptr_t`，整数转指针用 `void*` 转换 +- 不要假设 `long` 的宽度 + +--- + +## 3. 构建系统陷阱 + +### 陷阱 3.1：架构检测错误 + +**问题**：构建系统使用 `uname -m` 或自定义脚本来检测架构，但不认识 `loongarch64`。 + +**常见症状**： +- `./configure` 报错："Unknown architecture" +- CMake 选择了错误的编译选项 +- Makefile 中没有为loongarch64定义的条件分支 + +**修复方法**： +- autotools: 在 `configure.ac` 中添加 `loongarch64` 到架构列表 +- CMake: 检查 `CMAKE_SYSTEM_PROCESSOR` 的处理逻辑 +- 手动Makefile: 添加 `ifeq ($(ARCH),loongarch64)` 分支 + +--- + +### 陷阱 3.2：依赖检测失败 + +**问题**：LoongArch64环境下缺少某些依赖库，构建系统检测不到。 + +**预防措施**： +- 参考ebuild/PKGBUILD中的依赖列表，在LA64上逐一确认 +- 使用发行版包管理器安装缺失依赖 +- 记录LA64特有的依赖安装命令 + +--- + +### 陷阱 3.3：编译器标志不兼容 + +**问题**：项目使用了GCC特有的标志（如 `-march=haswell`），在LoongArch64 GCC上不识别。 + +**预防措施**： +- 检查 `-march=`, `-mtune=`, `-msse*` 等X86特有标志 +- 为LoongArch64替换为 `-march=loongarch64`, `-mtune=la464` 等 +- 使用条件编译而非全局编译标志（如可能） + +--- + +## 4. 测试验证陷阱 + +### 陷阱 4.1：X86-64测试本身就失败 + +**问题**：移植完成后，对比X86-64和LoongArch64的测试结果，但发现X86-64的某些测试本来就失败。 + +**后果**： +- 错误地将X86-64的已知失败归因于LoongArch64移植 +- 浪费时间在修复非移植相关的问题上 + +**预防措施**： +- 记录X86-64参考构建的完整测试结果 +- 区分"X86-64已知失败"和"LoongArch64新增失败" +- 移植报告中明确标注："X86-64基线：X个测试失败，LoongArch64：Y个新增失败" + +--- + +### 陷阱 4.2：仅验证编译通过 + +**问题**：移植后只在LoongArch64上编译通过，但没有运行测试套件。 + +**后果**： +- 运行时逻辑错误未被发现 +- 测试用例可能在运行时失败 + +**预防措施**： +- **编译通过不等于移植完成** +- 必须运行与X86-64相同的测试套件 +- 如果测试运行缓慢（如QEMU模拟），至少运行核心功能测试 + +--- + +## 5. Agent 行为陷阱 + +### 陷阱 5.1：过度自信——"这个改动很小" + +**问题**：Agent认为某个修改"只是添加了一个宏"，但实际上影响了全局编译流程。 + +**教训**：在跨架构移植中，没有"小"改动。每个修改都可能影响整个构建系统。 + +### 陷阱 5.2：望文生义理解构建系统 + +**问题**：看到 `Makefile` 就认为可以直接 `make`，没看到项目需要 `autoreconf` 或 `cmake` 预处理。 + +**教训**： +- 始终先阅读构建文档（README/docs/build.md） +- 检查是否存在 `configure.ac`（需要autotools）或 `CMakeLists.txt`（需要cmake） +- 不要盲目执行命令 + +### 陷阱 5.3：忽视构建日志 + +**问题**：构建失败后只看最后一行错误，没有阅读完整日志。 + +**教训**： +- 移植相关的错误可能在日志的早期就出现（如配置阶段） +- 使用 `make 2>&1 | tee build.log` 保存完整日志 +- 分析错误链，不只是最后一个错误 + +### 陷阱 5.4：未记录移植步骤 + +**问题**：Agent解决了构建问题，但没有记录具体做了什么，导致后续无法复现。 + +**教训**： +- 每个解决问题的步骤都应记录 +- 保存构建日志和错误信息 +- 最终生成可复现的移植指南 + +--- + +## 6. SIMDE 相关陷阱 + +### 陷阱 6.1：遗漏 SIMDE 依赖 + +**问题**：使用 SIMDE 头文件替换了 X86 SIMD 头文件，但系统未安装 SIMDE 包，导致编译仍然失败。 + +**预防措施**： +- 在使用 SIMDE 前，先检查系统是否已安装： + ```bash + pkg-config --exists simde && echo "SIMDE available" || echo "SIMDE not found" + # 或检查头文件 + ls /usr/include/simde/ + ``` +- 如果未安装，记录为依赖并安装（或通过发行版包管理器安装） + +### 陷阱 6.2：SIMDE 头文件路径错误 + +**问题**：使用了错误的 SIMDE 头文件路径，如 `` 写成了 ``。 + +**预防措施**： +- 严格参照 `la64-porting-guide.md` 第2.3节的映射表 +- 如果SIMDE版本较旧，某些头文件可能不存在，需确认版本兼容性 + +### 陷阱 6.3：`_mm_pause` 替换后引发性能问题 + +**问题**：将 `_mm_pause()` 替换为空后，自旋锁在空闲时占用100% CPU。 + +**预防措施**： +- 在文档中明确说明：`_mm_pause()` 在 LA64 上无等价物 +- 如果项目性能敏感，建议使用操作系统提供的同步原语（如 `futex`）替代忙等待 +- 在移植报告中注明此性能差异 + +--- + +## 7. Autotools 相关陷阱 + +### 陷阱 7.1：覆盖 config.sub 后未重新生成 configure + +**问题**：覆盖了 `config.sub` 和 `config.guess`，但没有重新运行 `autoreconf`/`bootstrap`，导致 configure 仍然不认识 loongarch64。 + +**预防措施**： +- 严格遵循 `la64-porting-guide.md` 第1.2节的流程：先覆盖 config 脚本，再重新生成 configure +- 可通过 `./configure --help | grep host` 检查是否支持 `--host=loongarch64-linux-gnu` + +### 陷阱 7.2：autoreconf 失败 + +**问题**：执行 `autoreconf -fvis` 时因缺少依赖（如 `aclocal`, `libtool`）而失败。 + +**预防措施**： +- 先确保 autotools 完整安装： + ```bash + autoconf --version + automake --version + libtool --version + ``` +- 在 ebuild/PKGBUILD 中查找 BDEPEND/makedepends 确认构建依赖 +- 在移植报告中记录需要的额外构建依赖 + +### 陷阱 7.3：系统 config.sub 版本过旧 + +**问题**：从 `/usr/share/` 找到的 `config.sub` 本身就不支持 loongarch64。 + +**预防措施**： +- 覆盖后验证：`./config.sub loongarch64-unknown-linux-gnu` +- 如果输出不是 `loongarch64-unknown-linux-gnu`，说明系统版本过旧 +- 从最新的 GNU config 仓库获取：https://git.savannah.gnu.org/cgit/config.git/plain/config.sub +- 或使用 `autoreconf -fvis` 时指定 `--install` 自动下载最新版本 + +--- + +## 8. 历史事件记录

的 `fcc` 相关汇编到 RV64，需重构逻辑 + +### 陷阱2：边界检查 + +- **LA64**: 有原生边界检查指令 `BCEQZ`/`BCNEZ` 和 `BOUND`系列 +- **RV64**: 无原生边界检查，需软件实现 +- **移植时**: 当看到 `bound.yml` 中的指令时，需将其展开为多条比较/分支指令 + +### 陷阱3：立即数构建 + +- **LA64**: 使用多条指令构建 64-bit 立即数：`LU12I.W` + `ORI` + `LU32I.D` + `LU52I.D` +- **RV64**: `LUI` + `ADDI` 构建低 32-bit，高 32-bit 需 `LUI` + `SLLI` + `ADDI` +- **移植时**: LA64 的 `LU32I.D` 和 `LU52I.D` 是特有的，不要简单映射为 RV64 的 `LUI` + +### 陷阱4：内存序一致性 + +- **LA64**: 原子指令的 `DB` 后缀表示强序，但非所有组合都是 SeqCst +- **RV64**: `FENCE` 和 `aq`/`rl` 位提供精细控制 +- **移植时**: 不要假设两者的原子序行为完全等价。LA64 的 Release Consistency 更弱，需更多显式屏障 + +### 陷阱5：SIMD 宽度错配 + +- **LA64 LSX** = 128-bit 固定宽度，类似 SSE/NEON +- **LA64 LASX** = 256-bit 固定宽度，类似 AVX +- **RV64 RVV** = 可变长度，`vsetvli` 设置 `vl` +- **移植时**: 不要假设 LA64 的向量长度与 RVV 相同。从 LSX 到 RVV
