Lecture 18
The most common way to transfer control in assembly language is to use a conditional jump. This is a two-step process: 1. First test the condition. 2. Then jump

Conditional Loop Instructions
LOOPNZ (LOOPNE) is a conditional loop instruction. • Syntax: LOOPNZ destination. LOOPNE destination. • Logic: • ECX ? ECX – 1;. • if ECX > 0 and ZF=0 jump

If the condition is false the program continues with the next instruction (PC?PC+1). • Below is a list of Conditional Branch instructions
Assembly Conditions
This is performed by a set of jump instructions j<condition> depending upon the condition. The conditional instructions transfer the control by breaking the
Project 4: Hack “Compilation” Examples
First rewrite the condition as (i - j <= 0) because all Hack conditional jump instructions com- pare their operand to 0. Put the 0 on the right-hand side
