Would you be OK with Pedro's suggested approach where we have
an additional macro that provides the number of ST registers?
That should get rid of the warning, and it seems like the code
might actually even be slightly better for it; it would make it
obvious that you iterate over a fixed number of registers, and
which ones you are interating over; [ST0 .. XMM0[ does not make
it as clear that the range only refers to ST registers, for instance.
