LLVM/Clang/LLDB/LLD
本节内容来自 LLVM Weekly 第 599 期, Alex Bradbury 大哥持续稳定输出。
马上就600期了!
C++越活越年轻: Herb Sutter posted a trip report from the June 2025 ISO C++ standards meeting. The big news was compile-time reflection being voted in to the C++26 draft.
志愿者绝赞召集中: Tom Stellard and Tobias Hieta are looking for volunteers to help with releases.
6月10日在东京的 AsiaLLVM 上提出的:Wendi Urribarri kicked off an RFC discussion on establishing a safety group in LLVM in order to discuss the challenges of using LLVM in safety-critical systems development (ISO 26262, DO-178C, EN 50128 etc).
AmirHossein PashaeeHir proposed upstreaming support for DWARF Call Frame Information (CFI) validation.
LLVM libc 越来越有希望了: William Huynh proposed a strategy for implementing stdio.h on baremetal for LLVM's libc.
思路看起来合理: Eugene Lomov proposed generating lld code with TableGen, such as the logic to apply a relocation to an encoded instruction.
有伙伴试过SFrame么: Sterling Augustine proposed adding support to the SFrame ("simple frame") format to LLVM. SFrame is a stack trace format aiming to enable fast, low overhead stack tracing.
MLIR Dialect 市场真是太火爆了: Sang Ik Lee proposes adding a XeVM dialect to MLIR, with the ensuing discussion clarifying various points.
基础设施的优化还在进行: Jessica Clarke suggested a policy of forbidding
@usernamein commits due to GitHub's irritating behaviour of sending out new email notifications every time the commit is cherry-picked or pushed to a fork.日积跬步: The RISC-V backend now supports non-power-of-2 types when expanding memcmp. ca29c63.
经典优化: Loop Invariant Code Motion (LICM) learned to hoist 'writeonly' calls. 1ab0e7d.
HLSL项目挺活跃的: HLSL descriptor table metadata parsing was implemented. b5d5708.
做编译器也需要学最新的AI了: Model Context Protocol (MCP) server support was added to LLDB. For now, it just supports one tool -
lldb_command. 9524bfb.

本周推荐:《一人公司》
作者:阿猫、鱼堂主
推荐:小编1号
有好几本书的名字都是「一人公司」但是作者和内容都是不同的。这本书是本土作者创作,自媒体和流量变现的方式。看完这本书就去开公司,是不太可行的;书中说的各种方式路径,放在今天看也不一定是能够有出头之日的。阅读这本书,或者说这类书,重要的是两个收获:
第一个收获,是能够在短短一个小时内看到(可能)跟自己目前的工作生活状态完全不同的工作生活方式、赚钱方式是什么样子的。不太会有人看一本书就立刻辞掉工作开始干自媒体,但是看了书之后回到自己日常的生活,看事情的角度、可以实践的方法组合范围、判断事情收益的模型,都有可能发生变化。
第二个收获,是看多了之后,就能感悟到,他人的努力,无论是多么可行,写出来之后,最艰难的部分都是无法文字表达出来的,也不会刻意的表达出来(否则就成伤痛虐恋系文学了)。纸上得来终觉浅,但是这个浅,好得不得了,省了很多麻烦。
