This blog post describes the optimizations enabled by -ffast-math when compiling C or C++ code with GCC 11 for x86_64 Linux (other languages/operating systems/CPU architectures may enable slightly different optimizations).
As is true for everything, a lot of things need to happen for anything to happen, and so it’s true for this blogpost as well. Out of all of these everything that needed to happen, 3 are these:
If you ever get a chance to look through the classic Amiga OS source-code still floating around some murky corners of the internet, it is a thing of beauty and astonishing capabilities. It’s an inspirational piece of computing history with unmatched capabilities for the time. Remember, this was all on a computer…

You can read the gritty details of how this is achieved, but for people coming across it for the first time, I think there is value in showing a simplified version, as once you've understood the simplified…
