Function Multi-Versioning: The Swiss Army Knife of Code

Hey tech tribe! 🗡️

Let’s talk about something that’s got all the versatility of a Swiss Army knife – Function Multi-Versioning (FMV).I know I have talked about it before but trust me it is different this time. It’s not just a fancy term; it’s a game-changer for developers juggling different CPU architectures.

Imagine you’re at a cook-off, and you’ve got to make a dish that impresses every judge with their unique tastes. That’s what FMV does for your code. You write a function, and FMV makes sure it’s the best darn function for every kind of CPU it might run on. Whether it’s x86-64 or aarch64, FMV has got you covered. It’s like having a single knife that can slice, dice, chop, and julienne – all with perfect precision! 🔪

There are a few ways to use FMV. You can manually create different versions of your functions, or let the compiler do the heavy lifting with something called automatic cloning. It’s like having a sous-chef who not only preps all the ingredients but also makes sure every dish is seasoned to perfection.

Our ultimate goal? To implement Automatic Function Multi-Versioning (AFMV) in GCC for aarch64. It’s the next evolution of FMV, making sure that your software isn’t just good, but great, no matter where it runs.

So, here’s to FMV – the Swiss Army knife in your coding toolkit, ensuring your code is always sharp and ready to impress! 🥳
