When translating conditionals or loops, the generated low-level code contains jumps. For the CPU to be able to execute a jump, the target of a jump must be a valid memory address. However, code generators typically generate jumps to symbolic addresses (labels). For example: beq exit Answer the following questions about symbolic addresses. i. What are the advantages of using symbolic addresses? ii. Which programs are responsible for translating such symbolic addresses to actual memory addresses? iii. How do code generators create symbolic addresses?

Question
When translating conditionals or loops, the generated low-level code contains
jumps. For the CPU to be able to execute a jump, the target of a jump must be
a valid memory address. However, code generators typically generate jumps to
symbolic addresses (labels). For example:
beq
exit
Answer the following questions about symbolic addresses.
i. What are the advantages of using symbolic addresses?
ii. Which programs are responsible for translating such symbolic addresses to
actual memory addresses?
iii. How do code generators create symbolic addresses?
