本节内容来自 LLVM Weekly 第 544 期， Alex Bradbury 大哥持续稳定输出。

• 问题不大： There will be one final, unscheduled LLVM release. LLVM 18.1.7 is expected on Tuesday, fixing a regression introduced in 18.1.6.

• 没看懂，有伙伴留言区解释下么？ There was further discussion on the proposal to introduce the 'sandbox vectorizer', with Alina Sbirlea indicating interest from some Google LLVM engineers in experimenting, Eli Friedman suggesting checkpointing via cloning as an alternative, and Arthur Eubanks offering a summary of pros/cons for various options for where this could live.

• 热闹： Stephen Tozer kicked off an RFC thread on updating how debug locations are handled in LLVM, suggesting making DebugLog a mandatory argument for creating instructions. This attracted a counter-proposal from Nikita Popov suggesting that this is enforced in the verifier instead.

• 看看： The 66th edition of MLIR News is now available.

• 国内伙伴？ Rong Xu and Han Shen posted a proposal for optimising the Linux kernel with AutoFDO includin ThingLTO and Propeller, including a variety of performance measurements.

• 日积跬步： The RISC-V backend gained a rematerialisable pseudo instruction for LUI+ADDI for global addresses. 2d00c6f.

• 很有希望： The SPIR-V backend gained support for llvm.ptr.annotation. f63adf3.

本周推荐：《失控》

作者： 凯文凯利

推荐： 小编1号

1994年的书，正好30年。出版后不到十年就因为书中的众多预测成为现实而名声大噪。而我则错过了这本书最火热的时间段，于是又顺理成章的错过了20年。

站在2024年阅读有一种不一样的感觉。这同时包含了考古和预测未来的时空重叠感，让我能够进入一种很难形容的内在冲突中，反思现在的科技生活中被忽视的不合理和不自洽之处。

感觉是时候成立一个「科技预测文献考古学」了，楽。
