This looks a bit odd to me. Just thinking out loud: your new logic is
there to be able to use a value even though it's not visible. In the
case where it's transitional you use the .config value instead of the
condition that makes it visible.
Could you simply change sym_calc_visibility() instead to always return
'yes' when the symbol is transitional? Wouldn't that simplify everything
in sym_calc_value()?
It's a tristate, so "m" is also possible besides "y". (sym->visible is
also a tristate. 🙂
That would be fine, right?
We'd pass the if (sym->visible != no) check... we'd do the
newval.tri = EXPR_AND(sym->def[S_DEF_USER].tri, sym->visible);
EXPR_AND() is basically min() (with n=0, m=1, y=2), so effectively it
would end up doing
newval.tri = min(sym->def[S_DEF_USER].tri, 2);
which is the same as
newval.tri = sym->def[S_DEF_USER].tri;
That's what your code is currently doing too, but in a much more
roundabout way.
