LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 662 期， Alex Bradbury 大哥持续稳定输出。

• （小心谨慎的促进社区的变革，治理大社区犹如烹小鲜）Reid Kleckner 提出了一个贡献者政策更新 RFC,该提案将引入一个与 "committers"(提交者)分开的 "reviewers"(评审者)团队(最初由现有提交者名单填充)。Tanya Lattner 担心该提案可能无法起到激励评审者的作用。
• （一代人有一代人的自行车）Nick Desaulniers 发起了一场关于在 LLVM 仓库中添加 AGENTS.md 文件的讨论。各方反应不一,一些人担心很难生成一份覆盖整个项目的 AGENTS.md,也有人指出 LLM 可以直接使用现有文档。
• （这个变动还挺大）Erich Keane 发布了一篇关于默认在 Clang 构建中启用 ClangIR 的 RFC。在表达担忧的回复中,一个常见的顾虑是编译时间成本。
• （好兄弟肩并肩）LoongArch 新增了一个受等价 RISC-V pass 启发的晚期分支优化 pass。7300edd。

本周推荐：《智能：AI时代的商业、组织与战略的本质》

作者：曾鸣

推荐：小编1号

我是通过“张小珺商业访谈录”接触到曾鸣教授的访谈的，他最新的书《智能》刚刚上市。其中涉及到了一些AI时代对于公司的组织形式的改变，以及未来会有什么样的机会，让我有了一些顿悟的时刻。也进一步的，让我意识到了，随着AI科技的发展，人的体面，尤其是老年人的体面，是人类幸福感提高非常重要的一个努力方向。
