LLVM/Clang/LLDB/LLD
本节内容来自 LLVM Weekly 第378期, 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, 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 and John Byrd 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, 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.
Zequan Wu kicked off a thread on annotating global functions and variables to prevent identical code folding during linking.
Lit's progress indicator is now more accurate, as it takes into account timings from previous runs. 好耶! 962339a5.

【RT-Thread开源作品秀】运动手表,该作品是基于ART-PI硬件平台,外接OLED,蜂鸣器,按键,X-NUCLEO-IKS01A3传感器套件完成实现的运动手表。运动手表应该能够兼顾温湿度,气压信息,指南针以及步数等,能够实时监控环境的状态。开源地址:https://gitee.com/hehung/travel-watch--rt--thread
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
往期社招及实习生招聘长期有效。
过去所有发过的招聘信息都还是有效的。都没有招满。如果感兴趣欢迎在微信公众号后台留言【招聘】咨询。 本周同时也新增了几个岗位。欢迎从历史信息中查看。

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。
