To get some protection, maybe one could define a function with the
desired api, say
mp_double_limb_t
mpn_gcd_11_for_gcd_22(mp_limb_t u, mp_limb_t b)
{
mp_double_limb_t g;
g.d0 = gcd_11 (u, v);
g.d1 = 0;
return g;
}
Then gcd_22 could tail call that function, and gcd_11 assembly
supporting that return type could override it to just be an alias.
As a bonus, one would get a more sane behavior if for some reason one
tries to use asm gcd_22 but C gcd_11 or vice versa.
