        * tree-cfg.c (verify_gimple_assign_binary): Allow
        MINUS_EXPR with lhs and rhs1 pointer vector and
        rhs2 sizetype vector.
        * expr.c (expand_expr_real_2) <case PLUS_EXPR>: For pointer
        or vector pointer use TER to optimize pointer subtraction.

        * gcc.dg/vect/pr45633.c: New test.
