the following test compiled with dmd 1.034 on linux should return via a hidden pointer parameter, but is actually returned in registers:

struct S
{
    int x;
    int z;
    static S foo()
    {
        S s = {1,2};
        return s;
    }
}

becomes

                push    EBP
                mov     EBP,ESP
                sub     ESP,8
                mov     dword ptr -8[EBP],1
                mov     dword ptr -4[EBP],2
                mov     EDX,-4[EBP]
                mov     EAX,-8[EBP]
                leave
                ret
