Here's a trivial test case:
$ cat test.hpp
#ifdef USE_PRAGMA
#pragma interface
#endif
class foo
{
public:
virtual ~foo() {}
};
class bar : public foo
{
public :
~bar();
};
$ cat test.cpp
#include "test.hpp"
#ifdef USE_PRAGMA
#pragma implementation
#endif
bar::~bar()
{
}
$ g++-4.0 -c test.cpp && nm --no-demangle test.o | grep _ZN3fooD
00000000 W _ZN3fooD0Ev
00000000 W _ZN3fooD1Ev
00000000 W _ZN3fooD2Ev
$ g++-4.0 -DUSE_PRAGMA -c test.cpp && nm --no-demangle test.o | grep _ZN3fooD
00000000 W _ZN3fooD2Ev
$ g++-4.1 -c test.cpp && nm --no-demangle test.o | grep _ZN3fooD
00000000 W _ZN3fooD0Ev
00000000 W _ZN3fooD1Ev
00000000 W _ZN3fooD2Ev
$ g++-4.1 -DUSE_PRAGMA -c test.cpp && nm --no-demangle test.o | grep _ZN3fooD
U _ZN3fooD2Ev
