陶立强同学低调的工作🎉: The initial implementation of a module level inliner was committed. 6cad45d.
希望疫情早点结束: The 2021 LLVM Developers' Meeting is taking place virtually this week, Nov 16th-19th.
开阔下视野: Simon Byrne blogged about dangers posed by 'fast-math' compiler flags.
有小伙伴关注么? Akash Kothari (on behalf of a consortium of authors) shared a proposal for TLX: Tensor LLVM eXtensions.
靠谱么? Mircea Trofin shared an RFC on applying machine learning to live range eviction for the 'greedy' register allocator, noting a 0.3%-1.5% improvement in queries per second on selected datacenter-type applications.
唉。 Zarko Todorovski is proposing to rename llvm-cov option -name-whitelist to -name-allow-list.
ORC JIT Weekly #44 is out, providing an update on support for MachO debugging.
LLVM GPU News #23 is out.
平头哥的CSKY架构: MC layer support for CSKY's 16-bit instructions was added. 4fb282f.

本周推荐:《杀死一只知更鸟》
推荐人:小编1号
非常知名的一本书,尤其是名字。不过我看完之后依然没有理解书名的含义。
故事本身发生在美国南部一个不繁华的小镇,黑人尚未有着今天这样的平等地位。全文看下来有着很明确的美国历史的年代感。
作者从一个不到10岁的小姑娘的视角,讲述了在小镇的日常生活,以及围绕着一起不算复杂的案件展开的惊心动魄。小编1号在阅读的时候感受最深刻的,竟然是十岁左右的小屁孩真是太能闯祸了(笑)。而小女孩的父亲,以及周围的几户邻居,在不同的时刻都体现出了人性的光辉。
需要有一些耐心,有一些连续的时间。只有在耐着性子阅读进去,能够想像出来小镇的地理格局和人物打招呼的情景之后,才能把自己带入到小镇中,体会到普通人在普通的生活中,同时展现出人性光辉的难能可贵,和自然而然。
