本节内容来自 LLVM Weekly 第 582 期， Alex Bradbury 大哥持续稳定输出。

• 3月12日之前注册可以优惠： Registration is now open for EuroLLVM, with early bird registration ending on March 12th.

• 欢迎！ Britton Watson introduced themselves as the new assistant program director at the LLVM Foundation. Welcome!

• CI Infra 在更新： Lucile Rose Nihlen provided a detailed update on the LLVM premerge infrastructure. "The plan for the Beta test is to keep the current infrastructure in production while enabling PRs to also be tested on the new infrastructure. During beta testing, PRs will have a new Github Actions check labelled LLVM Premerge. Initially we will have these set to pass regardless of whether or not the build/test passes or fails, purely to test the infrastructure."

• 社区的完善，虽然有一些不同意见： LLVM's developer policy was updated with new commit access requirements, with an explicit requirement that 3 committed patches are needed. ca0406d.

• RISC-V性能小微提升： A new RISC-V pass removes excess ADDI that can be reassociated and folded into a load/store address. 26e3750.

开篇第一个故事就非常的刺激。很适合找个阳光明媚的下午捧着一杯咖啡或者绿茶刺激的勾兑完。

任何时候，沟通都是一件复杂的事情，需要调用全身的肌肉和过去所有的记忆。
