Branches and Jumps

Up to now: sequential instructions (strictly in order)

What other kinds of instructions do we need (think of kinds of C statements)?

selection (if/else, switch)

looping (for, while)

function calls

There is no such thing as selection or loop statement in machine language

only the evil G-word (goto)

In assembly language, change the order of execution with a branch or jump

branch: conditional (not always)

jump: unconditional (always)

What does it mean to branch?
