hubert.reinterpretcast added a comment.
Noting for myself:
Clang's status quo already has behaviours that are similar to P2242R3 in its
C++20 mode despite those behaviours being non-conforming and contributing to
binary compat breakage with GCC.
This patch is not responsible for those behaviours, and fixing that status quo
is not within the scope of this patch.
Shorter test:
struct NonLit {
NonLit();
};
template <typename T>
constexpr int foo() {
return 42;
T t;
}
int (*f())() {
const int x = foo<NonLit>();
auto ff = [] { return x; }; // C++20 should error here; x is odr-used and
not captured
return ff;
}
