[PLMW@PLDI24] A Tour of Program Optimization

A Tour of Program Optimization (Video, PLMW @ PLDI 2024)
Max Willsey
(UC Berkeley)

Abstract: This talk will give a whirlwind tour through some topics in the wide world of program optimization. It offers a perspective that taxonomizes techniques into "transformation"…

今年 LLVM 社区的其中一个 GSoC 项目是重新设计 LLVM 主页，这是目前新 UI 的设计稿，这下好看起来了

C Macro Reflection in Zig – Zig Has Better C Interop Than C Itself

Zig’s reflection combined with Zig’s ability to import C header files means Zig can be used for C macro reflection.

⚛️ Apple 正式开启 Apple Intelligence 测试

Apple 在今日凌晨发布 iOS 18.1 第一个开发者测试版，开始启动对 Apple Intelligence 的测试。一直苦等 iOS 18 真正新特性的小伙伴坐不住了，希望第一时间尝试。

💡 新能力解锁
目前在 iOS 18.1 beta 1 中解锁的功能如下：

* 通话录音：会用 AI 的声音告诉你“我正在录音，请注意”。和 Zoom 会议中开启录制效果类似。

* 智能改写：可以将你输入的部分用 AI 重写，调整语气，调整篇幅长短等等。

🔒 冤种用户：锁硬件
目前为止 Apple Intelligence 为硬件锁，如果你的设备是在中国大陆、欧盟购买的，那么无论你的地理位置、IP 地址是什么，你都无法使用 Apple Intelligence 的任何功能。

香港和澳门不受影响；英国因为脱欧，因此也不受影响。Apple 可能后续会调整政策。

⬆️ 更新至测试版
如果你只希望更新 iOS 18 系列的 beta，不想更新至 macOS Sequoia，而且又怕 OTA 更新不稳，希望通过线刷的方式升级.

没关系，我帮你提取了最新 Xcode 的设备驱动，只需要在当前 macOS 安装这个驱动，你就可以通过 Finder 将 iPhone 升级至 iOS 18 系列测试版了。 详见评论区

Abstract interpretation in the Toy Optimizer

CF Bolz-Tereick wrote some excellent posts in which they introduce a small IR and optimizer and extend it with allocation removal. We also did a live stream together in which we did some more heap optimizations.

瑞士强制要求所有政府软件开源

瑞士 通过了名为《联邦电子政务法》（EMBAG）的立法，强制要求所有公共部门使用 开源 软件 (OSS)。 该法律规定，除非涉及第三方权利或安全问题，否则所有公共机构必须公开其开发或为其开发的软件的源代码。这一举措旨在提高政府运营的透明度、安全性，和效率。

Is performance reduced when executing loops whose uop count is not a multiple of processor width?

I'm wondering how loops of various sizes perform on recent x86 processors, as a function of number of uops.

Here's a quote from Peter Cordes who raised the issue of non-multiple-of-4 counts in ano...
