Question

I hate doing this problem so I'm just gonna type it here:

Do this in Y86 code:

long i = 0
if(i>=last) goto done

Answer 1

```
irmovq $0,&rbx #long i = 0
```

Answer 2

last is in %r12

Answer 3

Plan:
Store (last) on stack
Do last - i ==> last
Restore (last) from stack => last

if last - i >=0 then last >=i
so i must check if
last - i <= 0 so last <= i

```
irmovq $0,%rbx
subq 8,%rsp #make room on stack
rmmovq %r12,(%rsp)
subq %rbx,%r12 #last = last - i
jump if less than or equal to done
mrmovq (%rsp),%r12
addq 8,%rsp #clear room on stack
```

Answer 4

lol this hurts my brain so much
