LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 523 期， Alex Bradbury 大哥持续稳定输出。

• 2月4日截止： The call for proposals for EuroLLVM 2024 is now open and closes on Feb 4th (the conference will take place in Vienna April 10th-11th). Student travel grant applications are also open.

• MaskRay的年度总结： https://maskray.me/blog/2023-12-31-summary

• Nikita的年度总结： Nikita Popov blogged about their contributions to LLVM over the past year. Thank you Nikita for all of your contributions, especially the absolutely astounding number of reviews.

• 比较好的入门文章： Geoff Wozniak blogged about GCC spec files.

• 出了一点小小的意外： Phabricator remains down and seems like it won't be coming back. A partial read-only mirror is up at reviews.llvm.org but there are active discussions about missing reviews. MaskRay clarified the challenges in expanding the mirror and linked to some more extracted information that may be helpful to readers.

• 讨论仍在进行： There was further discussion on the llvm-project/offload roadmap thread, with Jon Chesterfield restating his objection to starting the library by modifying libomptarget rather than starting a new library and then porting OpenMP to using it. Johannes Doerfert responded to these concerns. Jon ultimately made a new RFC on introducing a GPU builtins runtime as a subdirectory under compiler-rt.

• 各位的 infra 可能要升级了： Ilya Biryukov provided an update on the suggestion to make Clang 17.0.6 the minimum version to build LLVM with C++20, reporting that the C++20 buildbot has been updated and is working fine.

• Adam Szilagyi started a discussion about suboptimal code generation for bitfield accesses through a pointer.

• 呼唤志愿者： Piotr Zegar is seeking reviewers to help with open clang-tidy reviews and provided a categorisation of open reviews.

• MLIR 真是火热的不得了： MLIR News issue 60 is now out.

本周推荐：《债》

作者： 大卫·格雷伯 译者： 董子云、孙碳 推荐： 小编1号

确实是很有意思的一本书，作者从一个我们从小就被教育成为常识的一个经济学概念 —— 以物易物过程很不方便所以出现了货币 —— 出发，提出质疑，从全球不同的文化部落中给出有意思的实证例子，提出了一个强有力并且很有意思的观点：从最早开始有以物易物开始，债务（有时候是人情）的概念就已经开始在不同的文化中存在。这让读者一下子有了另一个视角，去看待不仅是历史，而切看待自己当下的生活也多了更多的角度。
