Dear all,
I would like to post a bug 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>
X.CPP -oX.O
// file X.CPP
struct B1
{
void f (char);
void f (double);
};
struct B2
{
void f (int);
void f (double); // <--- line 10
};
struct D : public B1, public B2
{
using B1::f;
using B2::f;
void g ()
{
f ('a'); // should call B1::f(char)
f (33); // should call B2::f(int)
}
};
The compiler gives the following error message:
X.CPP:10: error: `void B2::f(double)' and `void B1::f(double)' cannot be
overloaded
I think this is not standard conforming. See 7.3.3/12: "[ Note: two using
declarations may introduce functions with the same name and the same parameter
types. If, for a call to an unqualified function name, function overload
resolution selects the functions introduced by such using declarations, the
function call is illformed. ]"
Kind regards
W. Roehrl

In 4.0, I get a different error message:
t.cc:16: error: using declaration using B2::f conflicts with a previous using
declaration

Hmm, This might be because we still have some ARM (pre-standard) based using
semantics implemented and not the standard C++ ones.
