LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 567 期，Alex Bradbury 大哥持续稳定输出。

• 填一下？ A survey is now up to better understand how MLIR develoeprs and users connect to the upstream infrastructure. Answers to this survey will help inform discussions on MLIR project governance and charter, so please do fill it in or pass on to others who use MLIR.

• 投稿了： The call for papers for the Compilers for Machine Learning (C4ML) workshop at CGO is now out.

• 首席鞠躬尽瘁： Nikita Popov proposed adding support for modelling errno memory effects, noting that right now LLVM has no way to model that a function can only write to errno in particular (as opposed to other memory locations).

• 文档mark之： In response to a question, Nikita Popov gave some illustrative examples for the difference between getelementptr nuw/nsw/nusw.

• 经常遇到的问题😂 Expectations about the handling of additional review comments after a 'LGTM' were documented. 41248b5.

• 有影响么？ Recursive types are now disallowed in LLVM IR. 4831e0a.

本周推荐：《控制论（cybernetics）》

作者：诺伯特·维纳

译者：郝季仁

推荐：小编1号

这本非常有意思的著作诞生于80年之前，看目录就很有意思，在多个领域融会贯通，打开了（不止一个）读者可能没有想过的视角，进而看到不一样的世界。

另一方面，本书非常成功，以至于书中很多知识在今天被当成了常识性的存在。

对于编译器或者IT领域的伙伴们而言，这本书的英文名字就挺出名的，补一补以后聚会吹牛肯定用得上。
