Questions >> Describe how to infer the correct answer. (for example, you need to explain where is variable i stored and how did you infer that from the assembly code).

Consider the following assembly representation of a function foo containing a for loop:

foo:

pushl %ebp

movl %esp,%ebp

pushl %ebx

movl 8(%ebp),%ebx

leal 2(%ebx),%edx

xorl %ecx,%ecx

cmpl %ebx,%ecx

jge .L4

.L6:

leal 5(%ecx,%edx),%edx

leal 3(%ecx),%eax

imull %eax,%edx

incl %ecx

cmpl %ebx,%ecx

jl .L6

.L4:

movl %edx,%eax

popl %ebx

movl %ebp,%esp

popl %ebp

ret

Fill in the blanks to provide the functionality of the loop:

int foo(int a)

{

int i;

int result = a+2;

for(i=0; i>a; i++ )

{

result += (i+5);

result *= (i+3);

}

return result;

}
