--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, here is a testcase which does not require C++20 (though it does use
a GNU extension):
struct X {
constexpr int f() { return 0; }
};
constexpr int g() {
return (X*){nullptr}->f();
}
int t = g();
---- CUT ----
here is one which is invalid C++14 (and does not use the GNU extension):
struct X {
constexpr int f() { return 0; }
};
constexpr int g() {
X *x = nullptr;
return x->f();
}
int t = g();
-------- CUT ------
I only noticed that clang rejects it while ICC and MSVC accept it also.
