Thanks for this p
`-no-integrated-as` is set?
Either way, I think it would be clearer to export this after all the
relevant flags are set.

I can of think that add_ss(), sub_ddmmss(), and umul_ppmm()
should be rewritten from the form:
asm("..." : "=r" (USItype)(arg) : ...);
to the form:
USItype temp = (USItype) arg;
asm("..." : "=r" (temp) : ...);
arg = (typeof(arg)) temp;
Rather than the flag being added.

What's the %y modifier supposed to mean here? addr is in the list of
inputs, so what's wrong with using it as an rvalue?
