MIPS Code:

main:
        push    rbp
        mov     rbp, rsp
        sub     rsp, 48
        mov     DWORD PTR [rbp-48], 12
        mov     DWORD PTR [rbp-44], 21
        mov     DWORD PTR [rbp-40], 3
        mov     DWORD PTR [rbp-36], 40
        mov     DWORD PTR [rbp-32], 15
        mov     DWORD PTR [rbp-28], 6
        mov     DWORD PTR [rbp-24], 17
        mov     DWORD PTR [rbp-20], 8
        mov     DWORD PTR [rbp-16], 29
        mov     DWORD PTR [rbp-12], 10
        mov     DWORD PTR [rbp-4], 0
        mov     DWORD PTR [rbp-8], 0
.L3:
        cmp     DWORD PTR [rbp-8], 9
        jg      .L2
        mov     eax, DWORD PTR [rbp-8]
        cdqe
        mov     eax, DWORD PTR [rbp-48+rax*4]
        add     DWORD PTR [rbp-4], eax
        add     DWORD PTR [rbp-8], 1
        jmp     .L3
.L2:
        mov     eax, DWORD PTR [rbp-4]
        mov     esi, eax
        mov     edi, OFFSET FLAT:_ZSt4cout
        call    std::basic_ostream<char, std::char_traits<char> >::operator<<(int)
        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     .L7
        cmp     DWORD PTR [rbp-8], 65535
        jne     .L7
        mov     edi, OFFSET FLAT:_ZStL8__ioinit
        call    std::ios_base::Init::Init() [complete object constructor]
        mov     edx, OFFSET FLAT:__dso_handle
        mov     esi, OFFSET FLAT:_ZStL8__ioinit
        mov     edi, OFFSET FLAT:_ZNSt8ios_base4InitD1Ev
        call    __cxa_atexit
.L7:
        nop
        leave
        ret
_GLOBAL__sub_I_main:
        push    rbp
        mov     rbp, rsp
        mov     esi, 65535
        mov     edi, 1
        call    __static_initialization_and_destruction_0(int, int)
        pop     rbp
        ret
