------- Comment #3 from rguenth at gcc dot gnu dot org  2007-02-22 11:04 -------
Confirmed.  Whoever wrote that code should be ....

typedef long unsigned int size_t;
typedef signed int sal_Int32;
typedef unsigned int sal_uInt32;
typedef unsigned long int sal_uInt64;
extern "C" void *memcpy (void *__restrict __dest, __const void *__restrict
__src, size_t __n) throw () __attribute__ ((__nonnull__ (1, 2)));
void callVirtualMethod(void * pThis, sal_uInt64 *pStack, sal_uInt32 nStack)
{
    sal_uInt64 *stack = (sal_uInt64 *) __builtin_alloca( nStack * 8 );
    memcpy( stack, pStack, nStack * 8 );
    register sal_uInt64 a0 asm("rdi");
    register sal_uInt64 a1 asm("rsi");
    register sal_uInt64 a2 asm("rdx");
    register sal_uInt64 a3 asm("rcx");
    register sal_uInt64 a4 asm("r8");
    register sal_uInt64 a5 asm("r9");
    sal_uInt64 pMethod = *((sal_uInt64 *)pThis);
    typedef struct {} ReturnValue;
    typedef ReturnValue (* FunctionCall )( sal_uInt64, sal_uInt64, sal_uInt64,
sal_uInt64, sal_uInt64, sal_uInt64 );
    ReturnValue aRet = ( ( FunctionCall ) pMethod )( a0, a1, a2, a3, a4, a5 );
}
