So, not order of magnitude then?

Yes, just look into how much effort you had to put vs my five minutes attempt.

The difference is between just using asm, or going out of the way to try to coerce a C toolchain to minimize the bloat.

Yea, large effort (objcopy, strip, sstrip), that I need to do only once, after that I already know how to do this an can just put it in a shell script. Now, I would like to know how quickly you'll be able to write a quicksort implementaion, that would outperform my C code, while being at least 25% smaller . Yeah, and how big your binary will become, once you link libc or opengl or whatever to make it able to do actual work.
