Hello,

I trying to port some code to linux using gcc. I am looking for
documentation on using 386 inline assembly with gcc ( __asm__). I've tried 
looking at the man or gcc ftp sites. Is their anything out their than
explains:

	assembly language format. (GCC's  386 assembly syntax is different 
		from the intel documentation).

   register conventions. ( For example, the return value is
		stored in eax).

Please let me know if any books or on-line documents exist for gcc.


A Linux question: Right now I trying to port over functions to talk
to hardware via the io ports( inp8, outp8, inp16, outp16, inp32, outp32).
For example, my old function to read a 16 bit word is:

/*------------------------------------------------------------
**  in16() - read a 16-bit word from I/O port
**------------------------------------------------------------
*/
ushort inp16( port )
ushort port;
{
    asm {
        xor    eax, eax
        movzx  edx, port[EBP]
        in     ax, dx
    }
}


I am tring to write equivlant functions in linux using 
inline assembly. I know the kernel has the inpb() function. This
is 8 bit(?). I wish to have a 8, 16, and 32 bit version of this
function. As anyone written one they can share with me?


Thanks,

Tony
