Greetings,

I tried compiling NetBSD-current (12/5/95) with gcc-2.7.2 and
encountered a little trouble with machine/pio.h

The offending lines are:

__inbc(int port)
{
	u_char	data;
	__asm __volatile("inb %1,%0" : "=a" (data) : "i" (port));
	return data;
}

and 


static __inline void
__outbc(int port, u_char data)
{
	__asm __volatile("outb %0,%1" : : "a" (data), "i" (port));
}


The compiler didn't like the "i" constraint much.

Even after consulting the gcc info pages, I'm afraid I must admit I
don't really know all of what is going on.


Anyway, I hacked out the i (actually, I made __outbc the same as __outb)
and compiled and everything linked fine (haven't run the kernel yet).

Anybody know what is going on?  Is this a gcc flaw, or is there a fix
that should be applied to pio.h?

Thanks,

Craig
