### LLVM/Clang/LLDB/LLD
本节内容来自 [LLVM Weekly 第378期](http://llvmweekly.org/issue/378),
[Alex Bradbury](https://www.linkedin.com/in/alex-bradbury/) 大哥持续稳定输出。
* On the LLVM blog, Arthur Eubanks provided a write-up of [the 'new'
pass manager](https://blog.llvm.org/posts/2021-03-26-the-new-pass-manager/),
detailing what it is, work that has been done to transition so far,
and next steps.
最近新旧 pass manager 导致提问题都经常出现鸡同鸭讲的情况。
* [Simon Cook](https://lists.llvm.org/pipermail/llvm-dev/2021-March/149367.html)
and [John
Byrd](https://lists.llvm.org/pipermail/llvm-dev/2021-March/149479.html)
further discussed the potential of using Tablegen to generate an
emulator core.
* Sjoerd Meijer started a discussion on [adding a function specialisation pass
to LLVM](https://lists.llvm.org/pipermail/llvm-dev/2021-March/149380.html),
noting that's it's frequently raised as a reason for performance differences
between GCC and LLVM and that the cost model is where previous proposals
have had issues.
* Philipp Reames [shared a patch to better document community norms
around
reverts](https://lists.llvm.org/pipermail/llvm-dev/2021-March/149409.html).
* Zequan Wu kicked off a thread on [annotating global functions and
variables to prevent identical code
folding](https://lists.llvm.org/pipermail/llvm-dev/2021-March/149352.html)
during linking.
* Lit's progress indicator is now more accurate, as it takes into
account timings from previous runs.
好耶! [962339a5](https://reviews.llvm.org/rG962339a5eca2).
### RISC-V in China
* RISC-V中国峰会正在筹备中,征稿和赞助已经开始。

### TVM / MLIR / AI Compilers
红红火火的开发中。不过好像整个AI的热度都已经降低了 —— 也有可能只是我没有再关注了 —— 这是个很主观的判断。
### 本周工具链岗位

### 本周推荐阅读
本周推荐:《文城》
作者: 余华
推荐人: 小编3号
《文城》讲述的是主人公林祥福为了给女儿找回母亲,一路南下来到溪镇安家立业,最终死于土匪之手的故事。故事不复杂,但作者能让故事中的人物都有血有肉。
读完《文城》,我的感受就一句话:“从苦难中看到人性的光辉”,这也是我对余华主要作品的感受,包括《兄弟》、《许三观卖血记》。《文城》给人的整体感觉,还是《兄弟》和《许三观卖血记》的延续,也仅仅是延续,并没有没有新的突破,也没有达到某些宣传所说的新的高峰。
一个作家想要突破自己的风格,超越自己的巅峰,是很难的。时隔八年,余华能有新作出来,作为读者觉得很欣慰,不奢求作品能达到新的高峰。文章本天成,妙手偶得之。
