From 4d320fb370af8371ec5c557d697a5624b95ca637 Mon Sep 17 00:00:00 2001 From: speak-agent <248744407+speak-agent@users.noreply.github.com> Date: Wed, 7 Oct 2026 19:58:24 +0900 Subject: [PATCH 01/28] Move the LLVM line to 23.1.3 and the macOS/Windows host defaults with it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 23.1.3 is the first point release carrying the macOS 27 arm64e.x1 ld64.lld fix (llvm-project#222721, backported to release/23.x as ee66426) — the release #669 was blocked on. clang 23.1.0's MSVC STL std-module defect was fixed in 23.1.1 (#640, llvm-project#218152). The line move (single PR per SPEC-009 §10.6): - kKnownTargets: the 17 llvm rows move 22.1.8 -> 23.1.3; the gcc rows stay. - Host defaults: macOS and Windows-with-MSVC move to llvm@23.1.3, resolving the [toolchain] macos/windows deviations (SPEC-009 §12). Linux keeps gcc@16.1.0 by design — native glibc ABI — now recorded as a §4.1 reason at the single pin site, with the gcc@15.1.0-musl reason beside it. - All four known-red legs (#669) become unconditional normal legs; the known-red floor assertion moves to zero. The xcode-27 legs went green on rerun and #669 is closed. - Readers move with the tables: workflows, the macOS action, CI tools, e2e fixtures, tests/matrix/expected.tsv, examples, user docs (en/zh); SPEC-009 v0.4 records the move. - libc++ 23 adaptation the gate caught: _LIBCPP_BEGIN_NAMESPACE_STD opens under the ODR-signature abi_tag pragma, and clang refuses to add abi_tag on a redeclaration — e2e 133's verbose_abort override now spells the namespaces by hand. The #782 repair: a held unserved-target diagnosis no longer skips the toolchain install. A declared or --target toolchain resolves and installs even when no payload here serves the target — a retargetable clang plus a graph package supplying the target's system is the arrangement the openkal rows exist for, and the skip fired before the graph release could run the moment the suite stopped installing the pinned version out of band (measured on the openkal macos leg, twice). When the install itself fails and the diagnosis stands, it releases there. e2e 890 pins the contract on the mac/windows legs. The e2e toolchain-version abstraction: tests/e2e/_toolchain_env.sh is the one place a test learns a toolchain version — override, newest installed, fallback constant, per family — and the llvm family's ~90 literals across 38 scripts now read it. The next line move edits one file here. _llvm_env.sh becomes an alias shim. Closes #780. Closed #669 (xcode-27 legs green on rerun). Files #782 as the remaining openkal macos regression this repair addresses. --- ...-2313-unified-default-cross-repo-design.md | 385 ++++++++++++++++++ .agents/docs/README.md | 7 +-

Add cold payload admission, complete xcode-27 shards, respect MCPP_HOME and capture Windows compiler failure evidence. Prepare release 2026.10.8.1. Native ARM64 remains preview until the coordinated resources and client release pass the measured integration gates.

+版本在执行前冻结；候选为当前依赖线 gcc-runtime 15.1.0、zlib 1.3.1、 +libxml2 2.13.5 与其已有配方修订，glibc 采用当前 2.44.3-r1 的上游 +源码与修补语义。LLVM 符号下界若高于候选 runtime，必须调整后再冻结， +不能仅因名称相同就认定二进制兼容。linux-headers 的版本下界由 glibc

build-glibc.sh 在源码、打包名及配方多个位置依赖 x86_64/lib64。 +需要参数化，而不是只给 archs 加 aarch64。保留其 loader 默认搜索路径、 +ld.so.cache、ld.so.preload、安装前缀 relocation 与 locale/gconv 修补。 +2.44.3 是索引包版本；其上游源码版本、修订与补丁集合分别记录。 + +推荐 aarch64 布局为 `lib/ld-linux-aarch64.so.1`、`lib/*.so*`、 +`include/`，runtime export 为 `abi = linux-aarch64-glibc`， +`loader = lib/ld-linux-aarch64.so.1`，明确 `libdirs = {lib}`。 +这是本方案指定的布局，构建与包验收必须使其成立，不能当作上游归档布局。 +x86_64 的 lib64 布局继续有效。loader 文件名、核心库清单、配置/检查中的 +libdir、辅助程序启动路径均来自同一架构描述。 + +### 4.4 架构路由与兼容性 + +每个配方必须同时核对：archs、版本可用集合、每架构 URL/sha256、 +依赖坐标、解包目录、runtime exports、sysroot 配置与测试。单独扩大 +archs 会让旧版本也被误报可安装；20.1.7/22.1.8 的 aarch64 缺席应继续 +是具名不可用，而不是尝试下载不存在的旧 ARM64 资产。 + +优先复用现有 libxpkg 的实际架构注入和资源解析契约。在加载 package +表的时刻是否能可靠读取目标架构，需要在发布版 xlings、mcpp vendored +xlings 两个入口上实测。历史文档曾记录 os.arch stub；本地较新 +libxpkg 已有 `__xpkg_arch__` 注入，这只提供检查方向，不证明已发布 +客户端具有同样能力。涉及 arch 选择的 loader/ABI metadata 不能延迟到 +install 回调后才修改，因为 resolver 可能已读取 exports。 + +若现有客户端不足，优先使用现有按架构资源契约或明确架构包坐标， +保持公开 `llvm@23.1.3` 在解析层可达；需要客户端能力时声明最小版本。 +此处设为兼容性门，未验证前不假定两仓库改动足够，也不先开新的协议。 + +### 4.5 发布内容不可变 + +新增 ARM64 资产可以挂既有 23.1.3 release；不能重写已发布的 x86_64 +同名文件。新资源有三方相同 sha256：carve、GLOBAL 重下载、CN 重下载。 +每架构每格式各自钉摘要，不共用 x86 哈希。错误资产需要具名 revision +与新文件名；不依赖 GitCode 覆盖同名文件。 + +## 5. mcpp：宿主默认、目标能力与构建链 + +### 5.1 只为 aarch64 增加默认分支 + +新增 `kFirstRunLinuxAarch64 = llvm@23.1.3`，在 +`pins::host_default_toolchain` 中显式区分 x86_64、aarch64、其他 Linux。 +保留 `kFirstRunLinuxOther`，避免 riscv64 等没有载荷的宿主被改成 LLVM。 +首次安装、self env、建议安装消息与默认值文档读取同一钉点。 + +新的默认产生 aarch64-linux-gnu，不能从此前 musl 的持久 target 或 GCC +解析惯例继承而出现 `LLVM 默认 + musl target` 的隐式组合。冷 home 的 +双轴断言是验收门；已有记录不强迁，显式用户选择仍保持优先级。 + +### 5.2 将 native GNU 行从 planned 转为实测支持 + +在原生 ARM64 Linux 完成编译、链接和运行门后，把 +`aarch64-linux-gnu` 提升为 verified；推荐该行 pin 为 `llvm@23.1.3`， +其语义是原生 glibc 工具链约定，不是禁止其他可服务编译器的能力锁。 +sysroot 来源按现有 runtime binding 机制接入受管 glibc 与 UAPI 头。 +若增加 sysroot 坐标，必须确认该字段确实被现有 hosted GNU 路径消费， +不能只在表上填值就宣称引擎已支持。 + +验证 `host_can_serve`、planned gate、toolchain list、why、matrix 扫描 +和实际 build 一致。原生 host 能用的 GNU 行不意味着 x86_64 Linux、 +macOS、Windows 已有 aarch64 glibc cross sysroot；这些组合仍给明确 +的 refusal 或 graph-supplied 支持，不升级为 payload-served。 + +### 5.3 按宿主与版本公布可用性 + +移除 `available_toolchain_indexes` 对 Linux aarch64 的 LLVM 全族隐藏， +但仍隐藏没有载荷的其他架构。允许列出 LLVM 族后，旧发行版列表必须 +按实际平台资源过滤，不把 20.1.7/22.1.8 也当作 ARM64 可装版本。 +替换 `check_aarch64_llvm_deferral.sh` 的历史否定门为正向安装门： +当前 line 的资源存在、架构正确、可安装且可启动。其他 deferred 组合 +保留各自的理由，不删掉所有保护分支。 + +### 5.4 mcpp 自举与宿主工具跟随新默认 + +根 mcpp.toml 的 `[toolchain] default = gcc@16.1.0` 不会因 first-run +默认变化自行变成 LLVM。推荐使用已有 +`[target.aarch64-linux-gnu] toolchain = llvm@23.1.3`；当前实现会在无 +`--target` 时应用 host row，CLI 指定仍优先。不引入未经实现的 +`[toolchain.linux-aarch64]` 拼法。对 native build 实测匹配到 GNU host +row；专用 CI 另显式传入工具链与目标，记录两种入口的结果。 + +build.mcpp、path host tool、import std/std.compat 和单测均用这套宿主 +运行链验证；musl 静态发布继续走显式 aarch64-linux-musl。bootstrap +可以仍是静态发布二进制，不要求发布程序本身依赖新 glibc 才能启动。 + +### 5.5 ABI 与系统库边界 + +glibc C ABI 可用于链接 C 系统库；这不等于 libc++ 可直接消费所有 +libstdc++ C++ ABI 的预制包。继续使用现有 ABI tag 与 prebuilt 校验， +GCC → LLVM 后旧 BMI、标准库模块与链接产物必须失效。 +测试 C ABI 依赖、共享库、pack 后运行、异常跨模块与线程；不默认允许 +跨标准库传递 std::string/std::vector。 + +## 6. 把 #781 review 缺口纳入交付 + +| Review 问题 | Part 2 的具体处理 | 完成判据 | +|---|---|---| +| xcode-27 缺第

头文件搜索、INTERP 和 loader 实际路径须证明使用受管闭包。 +4. 最终提交完成原平台回归与全部必要准入；原生 GNU 行依据实测提升， + 然后合入并发布。失败、挂起与 SKIP 均不能作为该门通过。 +5. 使用发布版执行 GLOBAL/CN 冷消费与 `xlings subos … --sandbox --cmd …` + 复验，记录隔离后端及有效索引。随后按 SPEC-009
