Hmm, the problem is that %1, %2, etc. is not very self-explainable.

May be %arg1, %arg2, etc.. But would that sound confusing since we
have % for registers?

As I sent right now, how about %argumentN ? it will not conflict with
register names...


There are archs that have %arg0 %arg1, ... as register names?

Well, arg(n) looks shorter but I won't personnally mind if
we eventually chose %argumentN. It's also clear, self-explainable
and it won't collide.

Hmm, one idea hits me, how about this? :)
- %register
- %%spvars (%%retval, %%arg0)

Thank you,
