Question

Translate the following C program to Pep/9 assembly language.

Answer 1

In this exercise we have to use the knowledge of computational language in C code to write a code that Translate the following C program to Pep/9 assembly language.

Writting the code:

• In C code:

#include <stdio.h>

int myAge;

void putNext(int age) {

int nextYr;

nextYr = age + 1;

printf("Age: %d\n", age);

printf("Age next year: %d\n", nextYr);

}

int main () {

scanf("%d", &myAge);

putNext(myAge);

putNext(64);

return 0;

}

• In Pep 9 CODE-

myAge:

.zero 4

.LC0:

.string "Age: %d\n"

.LC1:

.string "Age next year: %d\n"

_Z7putNexti:

pushq %rbp

movq %rsp, %rbp

subq $32, %rsp

movl %edi, -20(%rbp)

movl -20(%rbp), %eax

addl $1, %eax

movl %eax, -4(%rbp)

movl -20(%rbp), %eax

movl %eax, %esi

movl $.LC0, %edi

movl $0, %eax

call printf

movl -4(%rbp), %eax

movl %eax, %esi

movl $.LC1, %edi

movl $0, %eax

call printf

nop

leave

ret

.LC2:

.string "%d"

main:

pushq %rbp

movq %rsp, %rbp

movl $myAge, %esi

movl $.LC2, %edi

movl $0, %eax

call scanf

movl myAge(%rip), %eax

movl %eax, %edi

call _Z7putNexti

movl $64, %edi

call _Z7putNexti

movl $0, %eax

popq %rbp

ret
