Unfounded warnings in gcc-3.3

[Bernd Trog]

Hi,
I'm trying to inline a function with an asm() statment:

---------------------------------------------------------
#define PORTD 0x12

static inline void
write_byte( unsigned char adr, unsigned char data )
{
    asm("out %0, %1" : : "I" (adr), "r" (data)  );
}

void main(void)
{

  unsigned char i;

  for( i=0; i < 255;i++) {
    write_byte( PORTD, i );
  }
}
---------------------------------------------------------
>avr-gcc test.c  -Os -Wall -c -g

test.c:6: warning: asm operand 0 probably doesn't match constraints
test.c: In function `write_byte':
test.c:6: warning: asm operand 0 probably doesn't match constraints

Is there a way to get rid of the warnings other than deleting the
corresponding line in gcc/stmt.c?

Bernd
