The Darwin ABI specifies that this struct should be 12 bytes in size and have
4-byte alignment. Current
mainline gives it 8-byte alignment and 16-byte size.
struct ULL {
int X; long long Y;
};
ULL *ULLSize(ULL *ARG, int *P) { *P = sizeof(ULL); return ARG+1; }
In general, the special cases in the alignment hooks are special cased to
handle DFmode elements, but
should include DImode values as well.
