--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
For this reduced version (without the non-static function which is correctly
only getting one warning):
struct myclass{
[[deprecated("deprecated the static")]]
static void static_deprecate() { }
};
int main()
{
myclass v;
myclass::static_deprecate();
v.static_deprecate();
}
GCC 7 gives three warnings:
90451.cc: In function 'int main()':
90451.cc:10:14: warning: 'static void myclass::static_deprecate()' is
deprecated: deprecated the static [-Wdeprecated-declarations]
myclass::static_deprecate();
^~~~~~~~~~~~~~~~
90451.cc:3:17: note: declared here
static void static_deprecate() { }
^~~~~~~~~~~~~~~~
90451.cc:10:31: warning: 'static void myclass::static_deprecate()' is
deprecated: deprecated the static [-Wdeprecated-declarations]
myclass::static_deprecate();
^
90451.cc:3:17: note: declared here
static void static_deprecate() { }
^~~~~~~~~~~~~~~~
90451.cc:11:24: warning: 'static void myclass::static_deprecate()' is
deprecated: deprecated the static [-Wdeprecated-declarations]
v.static_deprecate();
^
90451.cc:3:17: note: declared here
static void static_deprecate() { }
^~~~~~~~~~~~~~~~
Notice the two different locations for the qualified call:
myclass::static_deprecate();
^~~~~~~~~~~~~~~~
myclass::static_deprecate();
^
The v.static_deprecate() call correctly only gets one warning.
But then with GCC 8 after r259067 there are three warnings for the qualified
call, with these locations:
myclass::static_deprecate();
^~~~~~~~~~~~~~~~
myclass::static_deprecate();
^
myclass::static_deprecate();
^
and two for the member access expression, both with the same location:
v.static_deprecate();
^
v.static_deprecate();
^
The regression due to r259067 is tracked by PR 67960.
