s_rectify will contain needed static_cast<> s type T can have in the program:

class A { int; };
class B { int; };

class P { int; };

class X : A, P { int; };
class Y : A, P { int; };
class Z : A, B, P { int; };


ptr<P>  = new (rc()) X;
ptr<P>  = new (rc()) Y;
ptr<P>  = new (rc()) Z;

ptr<P> ::s_id = 0;
ptr<X> ::s_id = 1;
ptr<Y> ::s_id = 2;
ptr<Z> ::s_id = 3;

ptr<P> ::s_rectify = {u, 4, 4, 8};

ptr<P> ::s_rectify[0] = int(static_cast<P *>((P *) 1) - offset(1)); // Not
defined yet
ptr<P> ::s_rectify[1] = int(static_cast<P *>((X *) 1) - offset(1));
ptr<P> ::s_rectify[2] = int(static_cast<P *>((Y *) 1) - offset(1));
ptr<P> ::s_rectify[3] = int(static_cast<P *>((Z *) 1) - offset(1));
