本节内容来自 LLVM Weekly 第 569 期， Alex Bradbury 大哥持续稳定输出。

• 2月1日有人去么？ This is a reminder that the FOSDEM LLVM dev-room CfP closes on December 1st.

• Herb Sutter published a trip report from the recent ISO C++ meeting in Wrocław.

• LLVM 19.1.4 was released.

• 中译英： The 16th Open Source Development Tools Conference (formerly HelloGCC Workshop) will take place on December 7th and is accepting submissions until November 30th.

• Regehr教授有很多影响力广泛的工作： John Regehr kicked off a discussion on improving constraint elimination in LLVM.

• 关注： Matthias Springer followed up on the MLIR thread on low precision FP types with a proposal.

• 有意思： Pavel Labath raised the issue of discontinuous functions in LLDB. Noting that tools like Propeller may split functions into smaller pieces, and although this is representable in DWARF, LLDB's internal representation doesn't allow for it.

• 传奇同学： ChuanqiXu proposed a ClangIR-based safe C++. There's plenty of interest in the details of the proposal, but also questions about its limitations and whether the timing is right for an RFC given that ClangIR is not yet mature.

• 欢迎关注： Kristof Beyls shared an update on the previous BOLT-based binary security analysis tool RFC to note that an initial PR is now up for review.

• 好： The RISC-V backend gained support for even-odd GPR pairs in inline assembly using the 'R' constraint. 4615cc3.

• 基础设施继续完善： Commit access requests can now be made via GitHub issues. 6fe94c3.

• 会有影响么？ The basic definition for "LLVM" as the environment part of a triple (as in x86_64-pc-linux-llvm was added, intended for use to indicate LLVM's libc. 7672216.

• 好： The formatting for LLDB's editline completion was improved. dd78d7c.

本周推荐：《新异化的诞生：社会加速批判理论大纲》

作者：哈特穆特·罗萨(Hartmut Rosa)

推荐：小编1号

这些年这个社会（全世界）是不是病了我一直说不好，但是确实是全世界都变得越来越快、越来越忙碌。《从前慢》这样的歌曲也广泛被传播和欢迎，体现这不是我一个人的感觉。很多时候都是觉得“没有必要这么卷吧”但是又无法自己先成为先停下来/慢下来的人，害怕成为慢下来的“代价”。

罗萨这本书非常薄，是另外一本五六百页的社会学术著作的通俗精简版本，以方便普通读者快速的掌握社会加速如何产生新的“异化”——“帮助快速的掌握”——简直就是这个社会加速的自我印证。罗萨指出这个社会加速来自于3个不同的方面，相互促进加速，使得过去的老时光一去不复返。

国内我感觉有了高铁就更快了，现在经常在南京、杭州和上海之间当天往返。百年前郁达夫从上海失业回杭州富阳老家，火车转步行还要坐小火轮，走了三天，有充分的闲暇花完了身上的钱并且完成了三四次想要跳河的心理过程。搁现在可能从出门到下高铁，全程都在回复微信和电话，抬头看风景的时间都不会有了。
