When I wrote my own EVM emulator I remember seeing the same 4 garbage instructions generated at the end (or beginning? I forget) of contracts depending on the tool used to generate said contract. I never cared to figure out why, and I still don't know why.

It’s called the BZZR metadata and it’s supposedly potentially useful for something.

it's the swarm link to the contract metadata/api. why it's not in the actual binary i have no idea.

It always felt a little strange running compiled Solidity contracts on mine. Compilers end up generating weird instructions sometimes.
