LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 628 期， Alex Bradbury 大哥持续稳定输出。

• 贡献和改进的机会： Nikita Popov wrote up a blog post on LLVM: the bad parts, noting "This is not a list of reasons to not use LLVM, it’s a list of opportunities to improve LLVM".

• 来了： LLVM 22.x will be branching on Tuesday 13th January.

• 有人用起来了么？ Yunbo Ni shared initial results from a research project on 'targeted testing' for LLVM, involving focused test generation for specific parts of LLVM.

• 所有程序员都需要注意： The LLVM Project Council reported that the LLVM AI tool policy proposal is now accepted.

• 底层系统软件的交织： Yonghong Song suggested a change to ThinLTO to benefit kernel live patching, specifically that static functions like <foo>() shouldn't be promoted to <foo>.llvm.<...>().

• 这是一个新环境的开始： Basic Mach-O triple support was added for RISC-V. 75d0251.

中文版也正好出版10年，现在看里面的思考，在今天都令人惊恐的复合（除了VR元宇宙的事情没跟上）。AI的发展太快了，人的隐私失去的太快了。这是KK的三部曲中的一部。每一本都推荐看看，当作“未来考古学”的一部分，从20年前的预言家审视今天的世界。
