本节内容来自 LLVM Weekly 第 639 期, Alex Bradbury 大哥持续稳定输出。
值得收藏: The final meeting working towards the C++26 standard has taken place, see Herb Sutter's trip report for more information.
这个有点步子很大: Jan Korous and Ziqing Luo proposed clang-reforge, an approach for whole-code source code rewriting for security hardening. The RFC outlines the various components, the implementation algorithm, and the motivation. "We propose creating clang-reforge, a whole codebase automatic source code rewriting tool that will change the code to be bounds-safe according to the C++ Safe Buffers definition. [...] We also propose creating bounds-safe alternatives to built-in C++ pointers and fixed size arrays that would work as drop-in replacements. The focus and purpose of these APIs will be enabling automatic large-scale adoption. In other words, we want to create them so it is feasible to write automatic adoption tools that will use them as replacements for built-in types."
感兴趣可以围观和参与: Federico Bruzzone is interested in any data on the individual contribution of LLVM passes to runtime performance.
稳定发挥: LLVM 22.1.2 was released.
很重要: LLVM's CI best practices doc was updated to note that credentials persistence should be disabled for GitHub's
actions/checkoutaction where possible. 8de3a47e.

本周推荐:《气呼呼的小词典》
作者:[意] 老安 / 卢悦
推荐:小编1号
非常好玩的一本书,非常适合碎片时间阅读。作者作为一个意大利人,在1980年代就开始住在中国了。这本书更像是“外国人在中国看中国”系列,让我们看到原来上世纪的时候,外国人来中国大陆还是有很多限制的,跟现在的大范围免签和全国一遍一遍优化旅游环境形成了鲜明的对照。
对了,老安还是《稍息:1981—1984年的中国》的摄影作者。我以前通过单向书店买过手袋,但是没注意到作者。看来这些相遇也都是命运的安排。
