临近春节，国内没有什么大型活动了。

编译社区的八卦信息

• “Linux 中国” 开源社区，停止运营 感谢硬核老王带给国内的1263期《硬核观察》视频以及这么多年对开源的无私贡献。一天不落的准备素材、剪辑视频是非常辛苦的事情，作为同行深有体会。祝愿老王能够在接下来的一段时间里如愿放松一段时间，如他在文章所言，爬山、摩托、散步、放松。

本节内容来自 LLVM Weekly 第 427 期， Alex Bradbury 大哥持续稳定输出。

• 国内有小伙伴打算去么？ The EuroLLVM 2024 event site is now live, along with ticket pricing details and precise dates for the event. Don't forget the upcoming talk proposals deadline on Feb 4th and the student travel grant deadline on Feb 5th.

• 时间过的太快了，18 要来了： The LLVM 18.x branch has been created, though note that 18.1.0-rc1 is delayed due to some issues moving the release process to PRs.

• 社区正在积极的适应新的 infra / GitHub：New 'requirements' were added for committing to the main branch. As later explained the intent is that an extra check box is needed when merging a PR from the web UI if any of the pre-commit checks are failing or nobody approved the patch. A warning message is also printed when pushing directly via git. As there was confusion about the change and whether it had received consensus.

• 社区正在积极的适应新的 infra / GitHub：Aiden Grossman started an RFC discussion on using GitHub Actions rather than Buildkite for precommit CI.

• MLIR 当之无愧是 LLVM 社区最火的项目： MLIR News #61 is now out, featuring some really detailed descriptions of some recent commits.

• 收藏： Bruno Cardoso Lopes initiated an RFC on upstreaming ClangIR, detailing the state of ClangIR today and changes made since it was previously discussed.

• 来自国内的小伙伴？ Mingming Liu provided an update on dynamic type profiling and optimisation in LLVM, pointing to a downstream end-to-end implementation and an initial pull request.

• 收藏： Michael Adams shared a new version of lecture slides covering Clang libraries.

• 做 Flang 的伙伴关注： Krzysztof Parzyszek posted a Flang RFC for splitting composite OpenMP directives when lowering.

• Reid Tatge is seeking land the previously discussed Machine Description Language in LLVM.

• 好耶！ The RISC-V backend gained support for the new relocation types needed by TLSDESC. 03a61d3.

• 什么，已经有C++26了？ The C++26 pack indexing feature (providing syntax for indexing packs of types of expressions) was implemented. ad1a65f.

好书。作者的想象力非常具体，当你阅读的时候有着自然直观的画面感，就好像我就身处于病毒爆炸开来的现场。

友情提醒当你打算在飞机上消磨时间时，这本书可能不是你最好的选择。我就是在飞机上翻开阅读的，之后整个人都不好了，感觉周围每一个在咳嗽的人都可能随时会呕吐出黑色和暗红色混合的液体，涨满整个呕吐袋，当递给空姐的时候又不小心掉到了地上。
