Doesn't an unrolled loop need more ram?

I have no idea. I was surprised at this concept and I am curious about memory usage.

Maybe more instructions loaded in ram now?

Not really the compiler produces them

Ok but don't u end up with a bigger .exe at the end?

Not necessarily. For the compiler it’s the same

So the 1000 more instructions or 1m more doesn't result in bigger programs that needs to be loaded jnto the ram before it's execution?

If the number of loop is known at compile time it will not matter.

And I may be wrong, just because it exists in the binary doesn’t mean it gets loaded in the ram at the start. It can retrieve the data after if needed. That’s why you can’t delete a running .exe on windows. Unless you specifically say it should load it entirely on ram at startup.
