First, off the volatile qualifier means "source-level reads/write must
turn into real loads and stores" so take that out of your declaration and
see how the code looks then. I don't know if the standard addresses the
interaction of volatile and register, but I'd expect volatile to win since
register doesn't actually mean anything (in the standard, at least).

Anyone know how to stop the register from being stored and read from on the
stack? We've defined it as
volatile register int idx asm("s0");
Show us the change you made to the MD file, or, if you didn't make a
change, show us the asm statement you are using.

Are you doing this inside or outside of a function? That is, a global
variable or not? The two cases act quite differently, as discussed
briefly in the documentation.
