LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 605 期， Alex Bradbury 大哥持续稳定输出。

• 现在还有能去美国的伙伴么： The agenda has now been posted for the upcoming US LLVM Developers' Meeting.

• 维护体系还在讨论： Renato Golin started a discussion on further fleshing out LLVM's maintainer policy.

• CHERI 在很多地方都有出现： Owen Anderson, Jessica Clarke, Alex Richardson, David Chisnall posted an RFC on upstreaming target support for CHERI-enabled architectures. As the post explains, more fine-grained RFCs will follow - the intent of this one is to get feedback/consensus on the overall direction of upstreaming. Respondents so far are all very positive.

• 看看这是啥： The MLIR project lighthouse repository is now online at llvm/lighthouse.

• 欢迎围观： LLVM Foundation Board meeting minutes have now been posted for meetings on February 28th, April 4th, May 9th, and June 5th.

• “强化模式”： Aaron Ballman, Shafik Yaghmour, Vlad Serebrennikov, and Corentin Jabot are seeking community feedback on a 'hardening' mode for Clang. As outlined in the RFC, although there are lots of choices to be made about how this is done, you could imagine enabling various -f, -m, -D, and -W flags by default. "We are looking for high-level direction from the community on how to proceed. Once we know that the community supports the notion of a hardened mode, and we know the general shape of how the community wants that mode surfaced, we intend to come back with a separate proposal for that particular path forward as well as the initial set of functionality enabled by that mode."

不管世界如何经历「有生之年」的变化，总有些事情是可以纯粹的、不变的、永恒的存在的。这就是数学。而代数的魅力则在于你可以获得随时随地仅仅依靠思考就能获得知识上的愉悦。更不要说通过代数的历史，可以看到人类作为一整个文明的进展。
