REg: inline assembly - Giridhar Tammana - Jun 25 10:42:19 2006

Hi,
I'm using c64x simulator.
I want to use swap2 instruction.
For this there is no intrinsic.

How can I write inline asm if possible to use swap2 instruction?

{
....
unsigned int val;
asm("swap2 val, val");
.....
}

asm("swap2 val, val");
above statement is wrong.
I also tried _val for val.
And GCC like asm("swap2 %0,%0"
                 :"r" val);
also doesnt work?
Pls reply if some thing we can do.
Thanks,
Giri

asm ("space val1,val2");
