How would you write this in MARIE assembly language?
int count = 0;
int number = 30;
int otherNum = 10;
while ( count <= number)
count += 3;
output = count/otherNum;
Solution
Answer:
.zero 1
main:
push rbp
mov rbp, rsp
mov DWORD PTR [rbp-4], 0
mov DWORD PTR [rbp-8], 30
mov DWORD PTR [rbp-12], 10
.L3:
mov eax, DWORD PTR [rbp-4]
cmp eax, DWORD PTR [rbp-8]
jg .L2
add DWORD PTR [rbp-4], 3
jmp .L3
.L2:
mov eax, DWORD PTR [rbp-4]
cdq
idiv DWORD PTR [rbp-12]
mov DWORD PTR [rbp-16], eax
mov eax, 0
pop rbp
ret
__static_initialization_and_destruction_0(int, int):
push rbp
mov rbp, rsp
sub rsp, 16
mov DWORD PTR [rbp-4], edi
mov DWORD PTR [rbp-8], esi
cmp DWORD PTR [rbp-4], 1
jne .L7
cmp DWORD PTR [rbp-8], 65535
jne .L7
