本节内容来自 LLVM Weekly 第 596 期， Alex Bradbury 大哥持续稳定输出。

• 学起来： Alex Denisov has authored the missing guide to dataflow analysis in MLIR.

• 得收藏： If you're interested in how RISC-V vector code generation has been developing in LLVM over the past couple of releases, I've written the talk I gave recently at RISC-V Summit Europe as a blog post.

• 得看看： There was quite a bit more discussion on the RFC on potentially changing LLVM's release process.

• 试试： Elvis Wang would like to introduce a new VPlan transform that conditionally executes vector basic blocks based on mask activity.

• 如期： LLVM 20.1.6 was released.

• 哇塞？ A device-side malloc implementation was implemented in LLVM's libc for GPU. b4bc8c6.

本周推荐：《当货币死亡：魏玛德国赤字开支、货币贬值和恶性通货膨胀的噩梦》

作者：亚当·弗格森(Adam Fergusson)

译者：梁金柱

推荐：小编1号

不要慌，说的是1922年的事情。德国战败之后，并不是立刻就某个落榜美术生上台的，而是经历了漫长的上千天之后。在这期间，每天汇率都在变动，工人时不时罢工要求涨工资，股市疯狂的繁荣。每一个处于时代中的小人物都在尽最大努力的进行着投资和储蓄，全然无法看到巨大的历史车轮的全貌。

认真阅读历史的细节，有时候会让自己觉得睿智无比。如果能够学以致用，则可能会在当下的大波浪中过得非常稳稳当当。
