Answer #1

Translation of given function in C to ARM code:
function(int):
push rbp
mov rbp, rsp
sub rsp, 16
mov DWORD PTR [rbp-4], edi
cmp DWORD PTR [rbp-4], 0
jg .L2
mov eax, 1
jmp .L3
.L2:
mov eax, DWORD PTR [rbp-4]
sub eax, 1
mov edi, eax
call function(int)
imul eax, DWORD PTR [rbp-4]
.L3:
leave
ret


Process by substituting 3 for N value:

call function(int)

imul eax, DWORD PTR [rbp-4]

.L3:

leave

ret

main:

push rbp

mov rbp, rsp

sub rsp, 16

mov DWORD PTR [rbp-4], 3

mov eax, DWORD PTR [rbp-4]

mov edi, eax

call function(int)

mov eax, 0

leave

ret

    Get the file “HW4Part4a.java” from the repository. Modify the program class to match the new file name. Complete it by writing a recursive static int function named “pow2” with one parameter, an integer n. The function is defined as follows: if n ≤ 0 then pow2(n) = 1. Otherwise, pow2(n) = 2 · pow2(n − 1). public class HW4Part4a { public static void main(String[] args) { for (int i = 0; i <= 20; i++) { System.out.println("pow2("+i+") = "+pow2(i)); }...
