For the C code below, if the variables a1 and a1p are changed to: int a1, int *a1p, and everything else remains the same. Then compile the C code to X86-32 assembly code (similar to the assembly code in Figure 3.29 which is X86-64 though).

Write the corresponding X86-32 assembly code and draw the stack frame for the revised function proc.
