The C code given below produces the following x86 assembly. Draw the stack frames for each of the following, showing the relevant stack contents and the addresses (write the addresses in relation to ebp, for example, ebp, ebp -4, etc.)

a) Stack frame of main at calll _f

b) Stack frame of function f at calll _g

c) Stack frame of function g after movl -4(%ebp), %eax

C Code:

int g(int x) { return x+3;}

int f(int x) { return g(x);}

int main() { return f(8);}

C Code and Assembly Equivalent:

int gCint x) return x+3;) int f(int x) return g(x);) int main) return f(8); pushl %ebp movl %esp, %ebp pushl %eax movl 8(%ebp), %eax movl %eax,-4(%ebp) movl -4(%ebp), %eax addl S3, %eax addl S4, %esp popl %ebp pushl %ebp movl %esp, %ebp subi S8.
