A question about varargs

[Mohamed Shafi]

Hello all,

I am involved in the porting of gcc 4.1.2 for 16 bit target. For this
target size of long long is 32bits. For the following code

#define VALUE 0x1B4E81B4E81B4DLL
#define AFTER 0x55

//void test (int n, long long q, int y);
void test (int n, ...);

int
main ()
{
  test (1, VALUE, AFTER);
  exit(0);
}

i find that the machine mode of the arguments of test are HImode,
DImode and HImode. When replace function 'test' with normal one
instead of varargs i find that the machine modes are HImode, SImode
and HImode respectively.
My question is even if the function is a vararg function shouldn't the
mode of the argument be SImode instead of DImode since long long is
only 32bit for the target?

Regards,
Shafi
