本节内容来自 LLVM Weekly 第 510 期, Alex Bradbury 大哥持续稳定输出。
羡慕,正在进行: The 2023 LLVM Developers' Meeting is of course going on this week and has a packed agenda. I unfortunately can't make it, but if you're there do be sure to attend the talk on vector codegen in the RISC-V backend by my Igalia colleague Luke Lau.
好文章,收藏: Nikita Popov blogged about scalar evolution in LLVM.
真是热火朝天: Galois open-sourced Yapall, (Yet Another Pointer Analysis for LLVM), a static pointer analysis tool for programming languages that compile to LLVM.
欢迎所有LLVM社区成员评论: Minutes from the July, August, September, and October LLVM Foundation board meetings were posted.
诶这是啥工作组: Andy Kaylor proposed the creation of a floating-point working group.
文档改进: NaN behaviour was specified more precisely in the LLVM language reference. d688816.
转正了: The RISC-V Zfa extension was updated to version 1.0 and is no longer marked as experimental. 18c3c46, eae1e28.
AMD GPU 的开源工作最近貌似很活跃的: Driver, preprocessor, and sema support was added for 'hipstdpar' for HIP parallel algorithm offload on AMDGPU targets. 9a40858.

本周推荐:《自卑与超越》
作者: [奥地利] 阿尔弗雷德.阿德勒 著
译者: 曹晚红
推荐: 小编11号
人们通常只有在遭遇失败挫折的时候,才会提出疑问“生活的意义是什么”,而本书给出的答案,是我目前最被感染想要付出行动的。这本书从1932年就已经出版了,我如果能更早看到它该多好,扼腕叹息~希望想(过)寻求生活意义的人们都能知道它。
本书虽然出版于90年前,但作者仿佛是看着你我长大的, 看着普通你我的生活从孩童时期到工作、爱情、婚姻、养育,看着那些焦虑、纠结、羞愧、嫉妒、愤怒的情绪笼罩在日常的生活中,他冷酷地揭露:你在自卑、逃避、懦弱、报复。我们每个人都有不同程度的自卑,因为我们都发现自己所处的地位希望加以改进,有人设定目标为追求优越感以避开自卑的情绪:别人都瞧不起我,我必须表现一下,让他们知道我是何等人物。所有追求优越感的人们的共同点在于,都有想要成为神的努力(那些主角逆袭站在金字塔顶端的小说、影视剧设计简直是深谙此道)。而另外一些人则更有勇气,他们选择设定目标为改变环境。改变环境要怎么做,作者给出的建议很温情:我们不去强调能从生活中获得什么,而是我们能付出什么。
