![Please convert the following C code to assembly Y86
int j,k;
.....
for (int i=0; i <5; i++) {
j = i*2;
k = j+1;
}
Solution
Answer:
MIPS Assembly Langauge Code :
.zero 1
main:
push rbp
mov rbp, rsp
mov DWORD PTR [rbp-4], 0
.L3:
cmp DWORD PTR [rbp-4], 4
jg .L2
mov eax, DWORD PTR [rbp-4]
add eax, eax
mov DWORD PTR [rbp-8], eax
mov eax, DWORD PTR [rbp-8]
add eax, 1
mov DWORD PTR [rbp-12], eax
add DWORD PTR [rbp-4], 1
jmp .L3
.L2:
mov eax, 0
pop rbp
ret
__static_initialization_and_destruction_0(int, int):
push rbp
