GNAT compiles the following illegal program.
generic
package P1 is
end P1;
with P1;
generic
with package the_P1 is new P1; -- [1]
package P2 is
end P2;
with P1;
package new_P1 is new P1;
with new_P1, P2;
package P3 is
package new_P2 is new P2(new_P1);
package my_P1 renames new_P2.the_P1; -- ERROR: the_P1 is not visible
end P3;
$ gnatchop -w p; gnatmake p3
splitting p into:
p1.ads
p2.ads
new_p1.ads
p3.ads
gcc -c p3.ads
gcc -c new_p1.ads
gcc -c p2.ads
gcc -c p1.ads
Compilation finished at Wed Apr 14 19:11:19
12.7(10):
"The visible part of a formal package includes the first list of
basic_declarative_items of the package_specification. In addition, if
the formal_package_actual_part is (<>), it also includes the
generic_formal_part of the template for the formal package."
Here, the formal_package_actual_part at line [1] is not (<>),
therefore the_P1 is not part of P2's visible part. Here is an example
where gnat correctly applies this rule:
generic
i: integer;
package P2 is
end P2;
with P2;
package P3 is
package new_P2 is new P2(3);
x: integer renames new_P2.i;
end P3;
$ gnatchop -w p; gnatmake p3
splitting p into:
p2.ads
p3.ads
gcc -c p3.ads
p3.ads:5:29: "i" is not a visible entity of "new_P2"
gnatmake: "p3.ads" compilation error
