本节内容来自 LLVM Weekly 第 608 期, Alex Bradbury 大哥持续稳定输出。
宋教授笔耕不缀: Fangrui Song has been busy blogging again, with recent posts on understandin alignment and improving sections and symbols in the LLVM integrated assembler.
RISC-V每日改进中: Luke Lau proposed removing codegen support for trivial vector prediction intrinsics in the RISC-V backend, as these have no advantage over the equivalent regular instructions and add burden in terms of additional test cases and code paths. The RFC has support so far.
祝贺进迭时空: MC-layer support was added for the SpacemiT vector dot product vendor specific RISC-V extension. 6842cc5.
推了有段时间了: A huge update was made to the documentation on pointer authentication. 62d2a8e.
QEMU (RISC-V)
- [PATCH qemu v10 0/1] target/riscv: Add Zilsd and Zclsd extension support https://lists.nongnu.org/archive/html/qemu-devel/2025-08/msg03474.html

本周推荐:《孤独消费论》

看起来像是一篇毕业论文装订成书了。作者设计了一些问卷,在一些区域/群体发放采样,按照性别人口经济状态等进行了分类分析。有一些看起来有点新意的观察和统计结果。
总体而言适合电子版本看看,纸质书籍估计买了之后觉得值得的不会太多。本身偏人文社科的统计调查。
有意思的地方还是有的。这是在日本的调查统计,根据以往的经验,日本和美国的社会结构性变化,比中国大陆要提前5-20年不等,近期十年有逐渐缩短的趋势。所以用日本的结论去对照看中国大陆的趋势,或许能做一些有意思的对比研究出来。
