Please convert the following C code to assembly Y86int i,j; ......pdf
0 likes3 views
The document contains a code conversion from C to Y86 assembly language, specifically for a conditional structure involving integer variables 'i' and 'j'. It includes assembly instructions for evaluating the condition, performing arithmetic operations, and managing function initialization and destruction. The assembly code demonstrates stack management and conditional jumps based on comparisons between 'i' and 'j'.

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