Реализация полиморфизма без virtual на C++: концепты, трейты и Ref

Как был переработан подход к полиморфизму в C++‑фреймворке Flox: замена virtual на статически сгенерированные vtable с концептами. В статье описана архитектура, проблемы, решение и метрики прироста производительности.

38c3: Hacking yourself a satellite - recovering BEESAT-1

In 2009, BEESAT-1 was launched into low earth orbit as the first 1U CubeSat of Technische Universität Berlin. In 2011, the satellite started returning invalid telemetry data. After a short amount of time spent diagnosing the issue, operators switc...

🌘 快速虛擬函數：為了趣味和利潤而黑客VTable
➤ 瞭解虛擬函數和VTable的運作原理，以提高效能。
✤ https://medium.com/@calebleak/fast-virtual-functions-hacking-the-vtable-for-fun-and-profit-25c36409c5e0
虛擬函數在架構設計中具有明顯的內在價值，能使架構更靈活，解決許多設計問題。兩派認為虛擬函數對於效能有不同看法：一派認為慢，一派認為現代編譯器和架構已使其效率提高。文章探討如何避免虛擬函數的效能損失、如何加速處理大量虛擬函數、如何檢測虛擬函數是否被覆寫，以及虛擬函數和VTable的基本原理。
+ 這篇文章解釋了虛擬函數如何影響效能，對於開發者來說很有價值。
+ 深入淺出地講解了複雜的概念，讓我對虛擬函數和VTable有了更清楚的理解。

Fast Virtual Functions: Hacking the VTable for Fun and Profit

Virtual functions have clear intrinsic value; using them can make architectures significantly more flexible and solve a plethora of design problems. When it comes to virtual functions (or methods…

#C #vtable == #CPP vtable

I've created a simple C-struct based v-table object and a C++
virtual class with the same methods. C and C++ apps could link both variants and apply native C or C++ method invocations to the same object pointers.

I run some tests on Windows X64 + ARM64 and on Linux x64 + ARM32 + RISC-V. No crashes, all succeeded.

Now I know: My virtual C++ classes have a C interface too. It's not a standard, but implemented by standard compilers. Nice! 🤓
