3 Write an assembly code that stores two different 2byte num
3. Write an assembly code that stores two different 2-byte numbers of your choice in two different memory locations of your choice (each number will actually use two memory locations because each number is 2 bytes), and that adds them and stores them in a third memory location.
Solution
Answer:
MIPS Assembly Language Code :
.zero 1
 .LC0:
 .string \"Addition of entered byte numbers: \"
 main:
 push rbp
 mov rbp, rsp
 sub rsp, 16
 mov DWORD PTR [rbp-4], 10
 mov DWORD PTR [rbp-8], 20
 mov edx, DWORD PTR [rbp-4]
 mov eax, DWORD PTR [rbp-8]
 add eax, edx
 mov DWORD PTR [rbp-12], eax
 mov esi, OFFSET FLAT:.LC0
 mov edi, OFFSET FLAT:std::cout
 call std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)
 mov rdx, rax
 mov eax, DWORD PTR [rbp-12]
 mov esi, eax
 mov rdi, rdx
 call std::basic_ostream<char, std::char_traits<char> >::operator<<(int)
 mov esi, OFFSET FLAT:std::basic_ostream<char, std::char_traits<char> >& std::endl<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&)
 mov rdi, rax
 call std::basic_ostream<char, std::char_traits<char> >::operator<<(std::basic_ostream<char, std::char_traits<char> >& (*)(std::basic_ostream<char, std::char_traits<char> >&))
 mov eax, 0
 leave
 ret
 __static_initialization_and_destruction_0(int, int):
 push rbp
 mov rbp, rsp
 sub rsp, 16
 mov DWORD PTR [rbp-4], edi
 mov DWORD PTR [rbp-8], esi
 cmp DWORD PTR [rbp-4], 1
 jne .L5
 cmp DWORD PTR [rbp-8], 65535
 jne .L5
 mov edi, OFFSET FLAT:std::__ioinit
 call std::ios_base::Init::Init()
 mov edx, OFFSET FLAT:__dso_handle
 mov esi, OFFSET FLAT:std::__ioinit
 mov edi, OFFSET FLAT:std::ios_base::Init::~Init()
 call __cxa_atexit
 .L5:
 nop
 leave
 ret
 push rbp
 mov rbp, rsp
 mov esi, 65535
 mov edi, 1
 call __static_initialization_and_destruction_0(int, int)
 pop rbp
 ret
