LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第 651 期， Alex Bradbury 大哥持续稳定输出。

• 今年有人计划去美国的 LLVM 开发者大会么？ The call for proposals is now open for the 2026 US LLVM Developers' Meeting, closing on July 14th. The Dev Meeting itself will take place on October 26th-28th in Santa Clara. Additionally the set of workshops has been announced, registration is already open, and applications for student travel grants are open.

• 这个技术点很难： Nikita Popov proposed an allocator provenance model. "We model memory allocation as 'creating' provenance and memory deallocation as 'destroying' provenance. This is reasonably well-defined in cases where the implementation of the allocator lives in a different module. However, it becomes unclear what exactly these terms mean when the allocator is visible in the same module. This RFC is an attempt to specify the provenance semantics of allocators in LLVM, and provide the means to correctly handle them even if asymmetrically inlined."

• 国内也有一些伙伴在贡献： Bruno Cardoso Lopes provided another status update on ClangIR upstreaming. An -fclangir-built clang can now compile about 93% of the translation units in the clang build graph (although the correctness of the compiled TUs has not been tested!).

• 招募维护者： Nikita Popov is querying if anyone is using the IROutliner and would step up to maintain it, in order to prevent it being removed.

• 支持： Vittorio Burani started an RFC Discussion on upstreaming support for the RISC-V OpenHW Group Core-V XCV vendor extensions as implemented in the CV32E40P core.

本周推荐：《无缘社会》

作者：日本NHK特别节目录制组

译者：高培明

推荐：小编1号

一开始以为是讲日本年轻人之间的不交流不恋爱，结果翻开之后大受震撼：本书讨论的是现在被称为“孤独死”的现状。不仅讲述了有关死亡后无法找到家属的情况，还描述了一个又一个人老死之后，没有家属愿意认领骨灰的情况。作者团队像是侦探一样刨根问底，去找到各种逝者存在过的痕迹。

我个人一直认为日本社会的种种现象在很多方面可以作为一种我们未来的可能性展示，包括全世界都有陆续出现的老龄化/少子化、死后无人继承遗产等问题，都有着陆陆续续的出现。通过这本书的阅读，或许能够有一些很好的洞察。
