本节内容来自 LLVM Weekly 第 435 期， Alex Bradbury 大哥持续稳定输出。

嗯？ LLVM 14.0.2 and 14.0.3 were released.
LLDB的文章比较少： David Spickett blogged about adding support for Arm's Memory Tagging Extension to LLDB.
又一年LPC要来了： The Call for Proposals for the toolchains and kernel track at the Linux Plumbers Conf 2022 is now open.
C++： Marek Polacek blogged about new C++ features in GCC 12.
议程公布了，等视频： The speaker for the May Women in Compilers and Tools meetup has been announced. Michelle Strout (professor in the Department of Computer Science at the University of Arizona an Chapel team manager at HPE) will host an AMA ('Ask Me Anything') session.
感情「毕业」也是硅谷来的么哈哈哈哈： The discussion on graduating CIRCT to the monorepo continued. A useful starting point for getting up to speed on that debate is Stella Laurenzo's summary of the discussion so far.
Hmm 啥？ Tom Honermann posted an RFC for supporting decimal floating point in Clang.
Alex Bradbury posted an RFC on representing WebAssembly tables in C/C++ or Clang.
有小伙伴看么？ LLVM GPU News #33 is out.
我其实一直没搞清楚过去一段时间的CoC在吵什么： As previously discussed on Discourse, the LLVM Code of Conduct was updated to remove the word 'draft' from all documents, add information about the CoC committee expectations, a place for transparency reports, and a complete reporting guide. eb2c30b.
