本节内容来自 LLVM Weekly 第 619 期， Alex Bradbury 大哥持续稳定输出。

很好的文章： Arm engineers blogged about their contributions to LLVM 21.
看不过来了： Peter Rong posted an RFC on providing open evaluation and better onboarding for MLGO (Machine Learning-Guided Optimization), reflecting on the various challenges people face when trying to use or evaluate things like MLGO for register allocation.
赞美，收藏： Slides are now available from the GPU/Offloading LLVM workshop. Additionally, notes have been posted from the Embedded Toolchain Workshop.
宋教授太勤奋了： Fangrui Song shared thoughts on a compact section header table for ELF.
大胆猜测下，什么时候会有基于 LLVM libc 的 Linux 发行版？ printf error handling was added to LLVM's libc. 9e2f73f.

KurisaW 提出为软件包引入可配置的 CI 编译与硬件测试框架，允许开发者按需勾选驱动模块，并支持硬件测试的自动化流水线 CI。目前提案尚未有人评论。详见: https://github.com/RT-Thread/rt-thread/issues/10928。
社区提出编写 PR 提交规范文档，统一贡献者提交PR时的相关规范性问题。https://github.com/RT-Thread/rt-thread/issues/10926。
目前社区针对 PR# 10537 争议性较大，上周社区例会召开后，对大家反馈的问题进行了一个了解，并提出两种优化方案, 详见 https://github.com/RT-Thread/rt-thread/issues/10927。
BernardXiong 提出对基础系统的 Group 进行整理，当前基础系统（Kernel, shell, libc/posix, file system, network stack, device subsystem）的 Group 划分显得很乱，很随意，需要对这些 Group 划分进行整理，变得简单清晰。详见 https://github.com/RT-Thread/rt-thread/issues/10904。

往期社招及实习生招聘长期有效。

本周推荐：《鸟类圣经》
