本节内容来自 LLVM Weekly 第 610 期， Alex Bradbury 大哥持续稳定输出。

宋教授笔耕不缀，是吾辈榜样： Fangrui Song blogged about changes in the LLD 21 release.
支持： Petr Hosek proposed that all unreviewed changes to the main branch in the llvm-project repo should go through a PR. The proposal still allows merging before CI checks finish, meaning quick fixes and reverts can still be made.
唉，又要开始折腾： Rick van Voorden wondered if use of the term 'sanity checks' should be moved to an alternative phrase.
可以买来看看： Quentin Colombet advertised his book, LLVM Code Generation: a deep dive into compiler backend development.
讨论了不少事情： LLVM Foundation board meeting minutes from August have now been posted.
太好了我们有救了： A new doc was started on debugging LLVM. 82978df.
加不完，根本加不完： Codegen and intrinsics for the proposed RISC-V Zvqdotq "vector quad widening 4D dot product" extension was implemented. 7fb1dc0.
这个好： SPEC can now be run as part of libc++'s own benchmarks. a40930b.
