LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 650 期， Alex Bradbury 大哥持续稳定输出。

• 看看： Herb Sutter shared a trip report from the June ISO C++ standards meeting in Brno.

• 欢迎加入： The LLVM Foundation is inviting applications for new board members.

• 日益急迫的问题： Aiden Grossman, Yunbo Ni, and Yingwei Zheng started an RFC discussion on providing infrastructure for AI review of PRs.

• 挺好的： Farid Zakaria is setting up a working group on solving the challenges of linking massive binaries in LLD. "The group would provide a platform for discussing cross-cutting concerns around relocation overflows, and modifications to the x86-64 ABI via code-models such as range-extension thunks."

• 不错的总结： Four months comes around quickly - it's time for another update on Flang development. As usual, this is a great high level summary of where things are at and what has changed in the past four months.

• 有意思： Alex Zinenko is seeking agreement within the MLIR contributor community on what to do with third-party project 'promotion' posts.

• 含金量！ The SpacemiT X60 scheduling model is now used for -mtune=generic for RISC-V. 5e8d406.

• RISC-V P 扩展，不容易： riscv_packed_simd.h was added containing RISC-V P extension intrinsics. b000f90.

• 日积跬步： LLVM's libc gained an LIBC_MATH_ASSUME_ROUND_NEAREST_ONLY build option. 582643f.

• RISC-V 日积跬步： LLDB learned to handle RISC-V feature attributes from ELF. 127a4c1.

本周推荐：《钢的交响》

作者：李瑞骅

推荐：小编1号

本书是共和国钢结构事业的开创者李瑞骅先生的回忆录。作者的一生，真的可以说是在波澜壮阔的历史背景下，丰富多彩又坚韧努力的一生。作者从自己的祖上开始讲起，那个时候一堆条件还不错的夫妻往往能够生育五六个、甚至八九个孩子；三世同堂、四世同堂的时候，就有了一个非常庞大的家族故事。作者在前几章中，往往一两页篇幅就讲述了一个人的一生，每翻一页都让我心生感慨，人生的无常和不易。
