LLVM/Clang/LLDB/LLD
以下值得关注的内容来自小编9号的整理和推荐(主要是 LLVM IR 变更):
- https://reviews.llvm.org/D156666 添加对 llvm.stacksave 和 llvm.stackrestore 的类型重载。此举的目的是使得 stacksave 和 stackrestore 可以用在非零地址空间。
本节内容来自 LLVM Weekly 第 502 期, Alex Bradbury 大哥持续稳定输出。
缩写也叫CAS: Steven Wu posted an update on upstreaming of the Content Addressable Storage in LLVM project, with links to patches now posted for review.
哦天呐 :) Vlad Serebrennikov noted that thanks to the contributions of a team of people helping to triage open bugs, LLVM now has below 20k open bugs. Thank you to everyone working on this!
学吧,学无止境: There were a couple of new RFCs for MLIR - firstly that almost all uses of TypeConverter should be const and secondly to fix floating-point 'max' and 'min' operations in MLIR.
x86上新的扩展: Phoebe Wang shared a design for AVX10 feature support in LLVM. AVX10 is a vector ISA evolution that includes all the capabilities and features of the Intel AVX-512 ISA in a converged version which can run on both E-cores and P-cores.

本周推荐:《郁达夫的杭州》
作者: 郁达夫
编选、摄影: 陆宗寅
推荐: 小编1号
首先郁达夫是一个作品非常丰富和人生经历非常跌宕起伏的历史人物,这本书肯定无法看到他的全貌,不能够仅仅以这一本书来评价郁达夫本人。
而这本书里的郁达夫实在是太有趣了。作者生于杭州市旁边的富阳,到杭州要坐船,从杭州到上海已经有了火车。有一段时间已经成家的郁达夫在上海混不下去,失业了,无奈之下让老婆孩子先回富阳老家,三个月之后依然没有混出动静的自己才决定回家。回家路上的内心描写将落魄长衫的心态描绘的真是让读者笑着笑着就可能哭了起来,1930年代的读书人跟2023年的中年人可能有着意料之外的相似。一路上就几元钱,一边内心哀叹没钱,一边漫无目的的游荡,导致钱越来越少。自责、彷徨、不甘,种种心态真是想在描写读者,而不是描写作者自己。
书超轻便,非常适合通勤和出差携带。
