Bounds-checking elimination

Bounds-checking elimination is a way for a computer to make sure it can trust the data it is given so it can work faster. Imagine you want to look for something in a big pile of toys. Normally you would have to check every single toy to make sure it's the one you are looking for. That would take a long time.

With bounds-checking elimination, the computer can look at the pile first. The computer can figure out where the toys stop and the other things start. By knowing the boundaries of the toys, the computer knows it only has to search the toys, not the other things in the pile. This means it can find what it needs much faster!

Bounds-checking elimination helps computers work faster by limiting the amount of checking it has to do.
