WebIn assembly, all branching is done using two types of instruction: A compare instruction, like "cmp", compares two values. Internally, it does this by subtracting them. A conditional jump instruction, like "je" (jump-if-equal), does a goto somewhere if the two values satisfy the right condition. For example, if the values are ...
