Question

Consider the following function where X, Y, Z, and W represent incomplete code. int math int a, int b, int c) int res1 X; int res2 Y; int res Z; int res 4 W; return res4 The function above is implemented in assembly code below where the function's parameters a, b and c are at the effective addresses 0x8 ($ebp), 0xc ($ebp) and 0x10 ($ebp), respectively. mov 0xc (%ebp),%eax not %eax mov %eax, -0x10 (%ebp) mov 0x10(%ebp) ,%eax mov 0x8 %ebp),%edx add %edx,%eax mov %eax, 0xc (%ebp) mov 0x10(%ebp),%eax imul $0x17,%eax, %eax mov %eax, 0x8 (%ebp) mov 0x10(%ebp),%eax sar $0x5,%eax mov %eax, 0x4 (%ebp) Choose the correct options for X, Y, Z and W to complete the function so that it corresponds with its assembly code.

Explanation / Answer

Your answers are correct as shown the assembly interactions are true

X is ~b

Y is a+res1

Z is c*23

W is c>>5
