Officially, java doesn't have unsigned types for economy: believe it or not,
Java was once intended to be a small language. However, there are not many
unused bytecodes left, and a full set of signed instructions would

Ah! Now however, I **must** know why Java doesn't have unsigned types!

There are multiple of issues here, first we have an issue that the java
front-end is not telling the middle-end that args.length cannot be changed
after a new has happened (an aliasing issue). And then we had some b

Aliasing is getting in the way of range propagation here. We don't realize that
args.length does not change during the loop, which means that we don't eliminate
the redundant load and fail to see the equi
