Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bruck.michael at gmail dot com
Target Milestone: ---
#include <coroutine>
#include <cstdio>
struct pt
{
using handle_t = std::coroutine_handle<pt>;
auto get_return_object() noexcept { return handle_t::from_promise(*this); }
std::suspend_never initial_suspend() const noexcept { return {}; }
std::suspend_never final_suspend() const noexcept { return {}; }
void return_void() const noexcept {}
void unhandled_exception() const noexcept {}
};
template <> struct std::coroutine_traits<pt::handle_t>
{ using promise_type = pt; };
static pt::handle_t foo()
{
printf("coroutine name %s\n", __builtin_FUNCTION());
co_return;
}
int main()
{
foo();
}

prints:
coroutine name _ZL3foov.actor
