本节内容来自 LLVM Weekly 第382期， Alex Bradbury 大哥持续稳定输出。

• The Women in Compilers and Tools Virtual May's Meetup takes place May 27th and presents Jessica Paquette's talk on Bringing up GlobalISel for AArch64. For information and to register see the listing.

• 比我快。 Frederic Cambus wrote a pair of articles on rapidly building Clang/LLVM. One on building it in 5 minutes on a 48 vCPU VPS and another doing it in 2 minutes on a 160 core AArch64 machine.

• 恭喜。 Kai Wang shared that initial support for RISC-V V extension v0.10 has now been merged upstream. As the extension is not yet ratified, this functionality is behind an experimental flag. This work has involved collaboration between the Barcelona Supercomputing Center, Codeplay Software, and SiFive.

• ORC JIT Weekly #33 and #34 are out. These updates cover recent work on the Orc runtime and JITLink.

• 更加智能。 LLVM is now built with -Wmisleading-indentation and (in a separate commit) -Bsymbolic-functions. f44c6f2, 4f05f4c.

• Support for WebAssembly globals in LLVM IR was added to the WebAssembly backend. d7086af.

• Unwinding from inline assembly is now supported. 8ec9fd4.

• MLIR gained PybindAdaptors.h, a file containing adapters for clients of the core MLIR Python APIs to interoperate via MLIR CAPI types. f13893f.

本周推荐阅读

本周推荐：《10人以下小团队管理手册》

作者: [日] 堀之内克彦

译者: 程雨枫

推荐： 小编1号

这本书比较小众，估计在书店看过的人不多，不过小编1号看过之后，觉得挺不错的。相比于德鲁夫的经理人、彼得·德鲁克的管理系列，这本书更加适合刚刚从技术人员变成主管的你，拿起来摆正一些态度和纠正从技术人员角度对管理的错误的认知。最最重要的，是这本书直接的告诉你，哪里的水深，你把握不住，如果对方满足不了共同的愿景等主张，就趁早交给其他人/团队来把握。这点能够显著的节约时间，减少新主管可能的挫败感。

推荐空闲的时候阅读，这本书翻起来也快，两三杯茶/咖啡的时间就可以。
