           Summary: please allow no_instrument_function attribute in class
                    member definition/declaration
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jojelino@gmail.com


it says
instrument.cc:10:6: error: canât set âno_instrument_functionâ attribute after
definition
isn't it false-positive? because in class/struct it is normal one to define
such member function in it.

#include <stdio.h>
struct t
{
public:
t();
__attribute__((no_instrument_function)) void a(){
}
void __attribute__((no_instrument_function))b(){
}
void c() __attribute__((no_instrument_function)){
}
void d() __attribute__((no_instrument_function));
};
void t::d()
{}
int main()
{
t a;
a.a();
}

$ g++ instrument.cc  -v
