Created an attachment (id=3674)
 --> (http://llvm.org/bugs/attachment.cgi?id=3674)
testcase

As I see all calls to internal functions ( like ___divdi3,___fixunssfdi, etc )
broken when them used with 8-byte primitives in 32-bit executable.

For attached test case llc produce following asm:
_getSomeInt:                                                ; @getSomeInt
; BB#0:
        sub     ESP, 20
        mov     EAX, DWORD PTR [ESP + 28]
        mov     DWORD PTR [ESP + 4], EAX
        mov     EAX, DWORD PTR [ESP + 24]
        mov     DWORD PTR [ESP], EAX
        mov     DWORD PTR [ESP + 12], 0
        mov     DWORD PTR [ESP + 8], 10
        call    ___divdi3
        add     ESP, 20
        ret


        ALIGN   16
        .globl  _main
_main:                                                      ; @main
; BB#0:
        sub     ESP, 12
        mov     DWORD PTR [ESP + 4], 0
        mov     DWORD PTR [ESP], 119
        call    _getSomeInt
        mov     DWORD PTR [ESP], EAX
        call    _putchar
        xor     EAX, EAX
        add     ESP, 12
        ret

See following bugs ( I think them are realated ):

I'm using 64-bit Windows and 32-bit LLVM tools.
