LLVM/Clang/LLDB/LLD
本节内容来自 LLVM Weekly 第 500 期, Alex Bradbury 大哥持续稳定输出。
就是后天了,冲呀! The call for speakers deadline for the LLVM Developers' Meeting has been extended to August 4th.
看呀! Even more video recordings from EuroLLVM were uploaded.
收藏之: Trail of Bits blogged about the future of Clang-based tooling, which discusses projects such as PASTA (a C++ and Python wrapper around much of Clang's API) and VAST, a new MLIR-based middle-end to Clang.
恭喜: Version 2.0.0 of the mold high-speed linker has been released, moving from AGPL to the MIT license.
有伙伴参与讨论了么? Alex Voicu shared an RFC on adding C++ parallel algorithm offload support to Clang and LLVM. It attracted a fair amount of discussion, covering issues such as the relationship with PSTL, libcxx, and Clang's extensions policy.
安全相关的工作? Anton Korobeynikov shared meeting minutes from the most recent LLVM pointer authentication sync-up and noted the plan is to now start meeting once a week.
MLIR 是真的火爆: Mehdi Amini kicked off a discussion about MLIR's relationship with LLVM releases, suggesting that effort to document changes from one release to another is increased and that the community considers backporting bug-fixes to the release branch when appropriate.
有兴趣的伙伴可以看看,layout reordering 的原理一般不难,适合初学者: A new code layout algorithm for function reordering was added. bc59faa.
Codegen support was added for the RISC-V BFloat16 zfbfmin, zvbfmin, and zvbfwma extensions. f375ee3, 2b6df4a.
OpenHW组织的扎实工作,来自ISCAS实习生的工作成果: MC layer support was added for the vendor-specific XCValu, XCVsimd, and XCVbi RISC-V extensions, used in the open source CV32E40P. 092e60a, 3c0604b, afb9c04.
好耶: Initial mapping symbol support for RISC-V was committed. a0d8a53.
龙团队加油: LoongArch gained support for
-march=nativeand-mtune. c56514f.LoongArch support landed in LLD. 6084ee7.

本周推荐:《宇宙》
作者: [美] 卡尔·萨根
译者: 陈冬妮
推荐:小编11号
我们来自哪里,将要去往何方?卡尔萨根的《宇宙》给出了最佳答案。作者是搞航天的, 但大概只有在科学、文化、政治、历史等所有领域都有过广泛阅读和思考的人, 才能够写出这本书吧,他把所有的知识都串联起来了。不仅仅是回答了人类, 更是回答了:知识来自哪里, 将要去往何方。
本书推荐给初中及以上的学生群体。 人类为了繁衍自身研究天空, 诞生了生物、物理、化学、天文等不同学科,这些学科并非割裂的, 它们共同诠释了物种、地球、恒星、星系、宇宙的演化。我们过往的学习中,绝大部分学科是至少从上百年的知识经验沉淀而来的,而其中的天文物理化学尤为特殊,它们是来自于存世几百亿年的自然法则 (想到这里,会觉得自己初中高真的学习了很了不起的东西啊)。科学不仅仅是课本和试卷上的考题,如果学生们在初中的时候就阅读了这本书,一定会怀揣着更多的好奇和更高的梦想去学习吧。
本书还推荐给或心灰意懒、或志得意满的人们。 地球几十亿年的演化才有了人类,有了珍贵的你。而与群星相比,人类又不过是朝生暮死的蜉蝣。你已经拥有的没有自以为的那么少, 而你此刻在意的也没有自以为的那么重要。 偶尔跳出细碎的生活和繁琐的工作, 跟随作者一起走进星空,既可以放松情绪,又能打开脑洞,或许还能写出另一部三体。
