Dear all,
I would like to post a fault report for the GNU C/C++ compiler 3.3-e500.
We use the compiler to generate code for a PowerPC processor.
Used invokation line for the GNU C++ compiler:
ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
-fmerge-templates -mmultiple -mno-string -mstrict-align -O3
-fno-exceptions -fno-rtti -fno-builtin-printf
-I<different include paths>
-D<differen #define's>
K.CPP -oK.O
// example program
template <typename> class C1;
template <typename> class C2;
template <typename T_>
class C2<T_*>
{
typedef T_* T_PAR_TYPE; <---- k.CPP, line 7
friend class C1<T_*>; <---- class C1<int (*)[20]> is a friend
};
template <typename T_>
class C1
{
//public: <---- k.CPP, line 14
typedef typename C2<T_>::T_PAR_TYPE T_PAR;
struct S1
{
T_PAR par; <---- k.CPP, line 18
};
static void fx (S1&);
public:
void f (T_PAR ptr);
};
template <typename T_>
void C1<T_>::f (T_PAR ptr_)
{
S1 s1; <---- k.CPP, line 31
fx (s1);
}
typedef int T_MEM[20];
void f (T_MEM* p1)
{
C1<T_MEM*> c1;
c1.f (p1); <---- k.CPP, line 45
}
The compiler gives the following error messages:
k.CPP: In instantiation of `C1<int (*)[20]>::S1':
k.CPP:31: instantiated from `void C1<<anonymous template type parameter> >::f
(typename C2<<anonymous template type parameter> >::T_PAR_TYPE) [with T_ = int
(*)[20]]'
k.CPP:45: instantiated from here
k.CPP:7: error: `typedef int (*C2<int (*)[20]>::T_PAR_TYPE)[20]' is private
k.CPP:18: error: within this context
The error messages remain the same if line 14 is un-commented. This seems OK
since the access specification of C1<>::T_PAR should not affect C1<>::S1. The
compiler translates only without complaints if C2<>::T_PAR_TYPE is made public.
With kind regards
W. Roehrl

Hmm. This code uses pointer to array, not pointer to
member as in PR c++/950. It's also a regression from GCC 3.2.x
but we didn't actually do access checking in templates in those
earlier versions.

Not a bug. You are using TPAR inside the class C1<T>::S,
however, only C1<T> is a friend of C2. This is the relevent section
of C++ standard (section 11.4 paragraph 2):
... the declarations of members of classes nested within
the friend class cannot access the names of private and
protected members from the class granting friendship. ...
and the example in the same section:
class A {
class B {};
friend class X;
};
class X : A::B { // ill-formed: A::B cannot be accessed
// in the base-clause for X
A::B mx; // OK: A::B used to declare member of X
class Y : A::B { // OK: A::B used to declare member of X
A::B my; // ill-formed: A::B cannot be accessed
// to declare members of nested class of X
};
};

Subject: Antwort: template friend declaration not recognized
Hi all,
I'm responding to the "Comments From lerdsuwa at gcc dot gnu dot org
2004-11-27 16:19":
I do not think that the cited standard rule (11.4/2) matches my example
because the nested class C1<T_>::S1 uses a name of its surrounding class -
namely C1<T_>::T_PAR. For the definition of this name class C1<T_> in turn
is referring to a name of class C2<T_*> - namely C2<T_*>::T_PAR_TYPE. And
class C2<T_*> grants class C1<T_> access to its private names.
Best regards,
W. Roehrl

The problem is GCC cannot distinguish between case #1 and #2
in the code below.
template <typename T_>
class C1
{
typedef typename C2<T_>::T_PAR_TYPE T_PAR;
struct S1
{
T_PAR par1; // #1
typename C2<T_>::T_PAR_TYPE par2; // #2
};
...
};

Patches partially fix this bug are submitted:
(for 4.0)
http://gcc.gnu.org/ml/gcc-patches/2004-12/msg00854.html
(for 3.4.4)

This should cover most likely failures, including the provided

Patches are withdrawn. They fail to deal with some more complex cases
and the approach used has to be overhauled.

------- Additional Comments From mmitchel at gcc dot gnu dot org 2005-04-17 04:10 -------
The TYPE_NO_ACCESS_CHECK_P sets off a red flag for me; that suggests that we're
at some point doing access checks directly on _TYPE nodes rather than _DECL
nodes. If so, that's wrong; only declarations have access associated with them.

The TYPE_NO_ACCESS_CHECK_P is there because we check
access on each tsubst TYPENAME_TYPE, regardless whether
the typename is actually appear in the code or it come from a typedef.
The patch was only intended for 4.0. For mainline, I am working on
the approach I mention as a stage 2 project. Still need some more time
to finish it.

Patch withdrawn due to overlooking default function argument and default
template argument. No nice solution is found yet.
