4. How are stack frames created in x86 assembly for recursive function calls? For this question, generate the assembly code for the following C code. (Note: gcc -S -m32 factorial.c will generate assembly and store it in factorial.s) int fact (int x) if (x>-1) return x*fact(x-1) else return 1; int main 0 int y fact (3); Study the assembled code and write a short paragraph on how stack frames are created for recursive calls
