--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. Paul, please post your patch to gcc-patches. Personally, I think
providing it under Clang's -Wunused-private-field for compatibility would be
preferable to disabling the warning altogether.
The top of trunk emits the following warning:
$ cat t.C && gcc -S -Wshadow t.C
class Foo
{
int foo;
public:
Foo(int foo) : foo(foo) {}
};
t.C: In constructor ‘Foo::Foo(int)’:
t.C:6:20: warning: declaration of ‘foo’ shadows a member of ‘Foo’ [-Wshadow]
Foo(int foo) : foo(foo) {}
^
t.C:4:11: note: shadowed declaration is here
int foo;
^~~
With -Weverything Clang emits the warnings below.
t.C:6:15: warning: constructor parameter 'foo' shadows the field 'foo' of 'Foo'
[-Wshadow-field-in-constructor]
Foo(int foo) : foo(foo) {}
^
t.C:4:11: note: previous declaration is here
int foo;
^
t.C:4:11: warning: private field 'foo' is not used [-Wunused-private-field]
int foo;
^
2 warnings generated.
